Inventor: TAGA MICHIHIRO
IPC: G11B33/14
Filed: 1994-03-31
Abstract: PURPOSE:To form a dust preventing apparatus which is compact, has high dust preventing properties, and is easy to exchange a filter. CONSTITUTION:A filter part 16 is fitted fully to an inner diameter of a fixed part 15. When the apparatus operates, the filter part 16 is tightly pressed to the fixed part 15 by leg parts 17c and a wind pressure. A slight gap is secured between a movable part 17 and the filter part 16. Therefore, the entire open air introduced into the apparatus from outside passes through the filter part 16. In addition, the flow of the air is not interrupted by the movable part 17. Accordingly, a maximum dust-proof area is effectively attained at a fixed area. The filter part 16 can be easily exchanged by pressing an arm 17a of the movable part 17 by a finger and detaching the movable part 17.

Title: Noise suppressing apparatus for engine ignition device
Inventor: KASUYA HIDEO
IPC: F02P15/00
Filed: 1981-06-10
Abstract: PURPOSE: To provide an ignition device, capable of reducing generation of noise wave effectively, by connecting a terminal of an ignition switch to a non-grounded electrode of a capacitor directly by a single lead wire, and connecting said  non-grounded terminal of the capacitor to an external resistance by another  lead wire.  
     CONSTITUTION: A terminal X of an ignition switch 2 is connected to a non- grounded electrode Y of a capacitor 9 directly by a single lead wire W1, and another lead wire W2 extended from the electrode Y is connected to a terminal Z of an external resistance 4. With such an arrangement, high-frequency current produced by the opening and closing of a contact point 7 and that induced by the spark ignition produced at a distributor gap 5 and a gap 6 of an ignition plug is passed necessarily to the electrode Y via the lead wire W2. Here, since the impedance of the capacitor 9 is extremely small for the electrode Y, high- frequency current causing noises is passed almost to the capacitor 9 but not  passed through the lead wire W1, so that it is enabled to reduce generation of  noise wave.

Title: Rubber composition and elastic body roller using it
Inventor: FUKUMOTO TAKAHIRO
IPC: B65H3/06
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide excellent resistance against ozone and high adhesive friction force by bringing JISA hardness within a range of specific numerical value and bringing loss tangent at a specific temperature within a range of specific numerical value. SOLUTION: If JISA hardness is less than 20 degrees, an elastic body roller becomes too soft and has insufficient rigidity, causing irregular friction. If it exceeds 30 degrees, the elastic body roller is not easily deformed and does not give high adhesive friction force for paper. Moreover, if loss tangent at 50 deg.C is less than 0.02, the impact absorbency property is scarcely obtained, the follow-up property to paper is greatly reduced, and the paper feed performance is greatly reduced. If it exceeds 0.035, energy loss in a slip condition with paper increases, slide resistance increases, and a wear amount increases. In this way, it is preferable to blend oil and plasticizer to reduce hardness.  Moreover, it is preferable to reduce an amount of plasticizer which is added as much as possible and comparatively increase an amount of vulcanizer and vulcanization promotion agent which are blended in order to reduce slide resistance.

Title: Incinerator
Inventor: RYU TADASHI
IPC: F23G5/44
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To enable sufficient incineration of even large quantity of matters to be incinerated while simplifying the disposal of ash after the incineration by a method wherein an opening-closing lid is provided with, a stack and a scattering prevention net disposed at a discharge port of the stack and an air introduction port is formed in a surrounding wall of an internal incinerator while a grip is provided at an upper part thereof. SOLUTION: Garbage is dumped into an internal incinerator 2 and after the ignition thereof, an opening-closing lid 10 is closed. When the garbage in the incinerator 2 is burned, combustion air is introduced at an air introduction port 12 at a lower part thereof and enters into the incinerator through air introduction holes 20 provided over the entire surface in the incinerator 2 to prompt combustion. The combustion gas ascends along the side wall of the opening-closing lid 10 to be released outside via a stack 100. In this process, the ash of burned paper tends to be released by a lift of the combustion air but is prevented from going outside by a scattering prevention net 101 at an opening part of the stack 100. After the end of the incineration, a grip 22 is held to take the incinerator 2 out of the body of the incinerator 1.  Thus, all of the ash generated by combustion is taken outside the body 1 of the incinerator.

Abstract: PROBLEM TO BE SOLVED: To perform signed division without converting the negative value of a dividend and/or a divisor to a positive value by comparing the absolute values of a part of a partial remainder and the divisor, turning the quotient of the digit to '1' in the case that a part of the partial remainder is larger or in the case that both are equal and turning it to '0' in the case that it is smaller. SOLUTION: This circuit is provided with a first comparator 9 for comparing the signs of the dividend and the divisor, a comparator 10 for comparing whether or not the sign of the result of an arithmetic operation performed in an adder-subtractor 5 is the same as the sign of the partial remainder and a control circuit 11 for receiving the arithmetic result of the adder-subtractor 5, the discriminated results of discriminators 7 and 8 and the compared result of a second comparator 10, deciding the quotient and controlling the selection of a selector 6, etc. In the circuit, in the division process of a recovery type or a non-recovery type in a signed state, the absolute values of a part of the partial remainder and the divisor are compared.  Then, the quotient of the digit is turned to '1' in the case that a part of the partial remainder is larger or in the case that both are equal and the quotient is turned to '0' in the case that it is smaller. Thus, division time is shortened.

IPC: G03G15/00
Filed: 1990-04-04
Abstract: PURPOSE:To always perform stable electrostatic charging for whatever environment by utilizing a means for heating an electrostatic charging means. CONSTITUTION:The electrostatic charging means 2 is provided with the heating means 7 for heating the means 2. For example, it is assumed that an electrostatic charging roller 2 press-contacts with an image carrier 1 which is formed in a cylindrical shape and rotates and travels in a direction shown by an arrow, and the surface of the image carrier is uniformly electrostatically charged by impressed bias by a power source 5. Then, a temperature detector is provided in a proper part near the end of the hollow metallic pipe 6 of the roller 2. When a detected temperature is lower than a reference value, the power is supplied to the heater 7 inside the pipe 6 so as to raise the temperature of the roller 2, and when it is higher than the reference value, the power supply to the heater 7 is cut. Thus, the image carrier 1 is always stably electrostatically charged without receiving the effect of the environment.

Abstract: PURPOSE:To obtain a recording generating no tailing, by providing a heat generator selectively generating heat in accordance with an image signal, a spacer holding the heat generator and a recording medium to a non-contact state and a temp. gradient part for cooling a recording dot. CONSTITUTION:When a voltage pulse is applied to a heat generator 7, the heat generator selectively generates heat and the ink 3 therearound is melted to be lowered in its viscosity. Then, the ink 3 begins to flow out from an ink passing hole 8 to spread in a space 13. The molten ink 3 fully spreads then in the region where the heat generator 7 is present. At this time, the generation of the heat from the heat generator 7 stops and, at the same time, the radiation of heat begins and the viscosity of the ink 3 increases to stop the outflow of the ink 3. Next, the ink layer is separated into the layer covering the heat generator 7 and the layer transferred to recording paper 10 with the movement of the recording paper 10 to form a recording dot 12 on the recording paper 10 and the state of the heat generator 7 returns to the initial state. In the above-mentioned process, by providing a cooling part 14 on the downstream side of the heat generator 7 with respect to the recording paper 10, a heat radiation property becomes good and the viscosity increasing time of the ink 3 becomes fast.

Title: Charging electricity generator for vehicle
Inventor: IWAKI YOSHINORI
IPC: H02K9/06
Filed: 1979-07-11
Abstract: PURPOSE:To suppress the noise of a fan below a prescribed level,by using leakage flux extending through a rotor shaft, to magnetize a gear-shaped iron member  secured on the shaft and by applying electromagnetic clutch action to rotate the fan. CONSTITUTION:A gear-shaped iron member 1a is secured on a rotor shaft 7 and opposed to an electroconductive cylindrical member 4 secured on a fan 3, thereby providing an electromagnetic clutch. The iron member 1a is magnetized by leakage flux which is produced when a voltage is applied to an exciting coil 5. As a result, a single pole is produced and an induced current is caused in the electroconductive member 4 to rotate the fan 3, The rotational frequency of the fan rises until torque acting to the fan 3 due to air resistance becomes equal to that due to an electromagnetic force between the iron member 1a and the electroconductive member 4. The rotational frequency is constant after the former torque becomes equal to the latter. Therefore, the noise of the fan is prevented from exceeding a prescribed level.

Title: Overspeed preventive device of internal combustion engine
Inventor: SESHIMO YOSHIMI
IPC: F02D11/08
Filed: 1987-04-13
Abstract: PURPOSE:To prevent overspeeding of an engine by providing an oscillation sensor that opens into the air a pressure chamber of an oscillation pump energizing a throttle vale toward the valve closing direction by virtue of the oscillation at the time of overspeeding for the purpose to make the throttle valve actuate automatically toward the closing direction. CONSTITUTION:Under a normal engine operation, the oscillation of a weight 44 is restrained and the pump operation is interrupted because a passage 49 to an oscillation pump 41 is closed by a ball 107 of an oscillation sensor 101. When an overspeeding condition takes place at this stage, the ball 107 of an oscillation sensor 101 starts to act violently resisting the force of a spring 104 and, as a result, passage 49 opens. A diaphragm 58 as well as the weight 44 oscillate as the oscillation pump 41 thus receives the oscillation from the engine. The positive pressure or the negative pressure air is consequently fed to the pressure chamber 85 of an actuator 81 causing a valve stem 28 as well as a throttle valve lever 29 to rotate by a projected rod 92 and the opening of a throttle valve 27 to reduce. The amount of air-fuel mixture fed to the engine is reduced and the overspeed of an engine is automatically prevented in this manner.

Abstract: PURPOSE:To ensure a duty easily to an input signal at high speed by mounting an emitter follower circuit for a lateral P-N-P transistor to an input buffer section, connecting a base input for the emitter follower circuit to an input- signal pad and connecting an output from the input-signal pad to a CMOS gate. CONSTITUTION:An emitter follower circuit for a lateral P-N-P transistor 1 is set up to an input buffer section for a CMOS gate array semiconductor device, a base input for the emitter-follower circuit is connected to an input-signal pad 6, and an emitter output is connected to a CMOS gate. Consequently, voltage is shifted in the forward direction only by a forward voltage section between an emitter and a base for the P-N-P transistor 1 from a signal inputted from the outside in a signal inputted to the CMOS gate. Accordingly, even when an external input signal is an input signal at a TTL level, a signal received by the CMOS gate is made higher than the external input signal, and the channel conductance of an NMOS and a PMOS for the CMOS gate can be set equally, thus improving the balance of the rise and fall of an output waveform, then easily ensuring a duty at a time when a signal at high speed is inputted.

Abstract: PURPOSE:To permit to form the uniform thin multi-axially orientated sheet by compression forming by a method wherein the sheet or the film of thermoplastic resin, having specified draw ration per unit area as well as thickness and small in a difference between the maximum polarized fluorescent component strength IMAX and the minimum polarized fluorescent component strength IMIN, is employed as the material of the sheet or the film. CONSTITUTION:The orientated sheet of the orientated film of thermoplastic resin, having 2X or more of draw ration per unit area and the thickness of 1mm or less while the difference between the maximum polarized fluorescent component strength IMAX and the minimum polarized fluorescent component strength thereof is in the relation of IMAX-IMIN/IMAX<0.1, is employed for the compression forming. Here, the polarized fluorescent component strength means the same strength in all angular direction, which is measured by a polarized fluorescent light photometer when the axes of deflection of two sheets of polarizing plates, which are put before and after the sheet or the film, are arranged in parallel. The draw ratio per unit area of the sheet should be 2X or more and is preferable to be 3X or more and 20X or less. When it is 2X or more, the effect of orientation is realized generally and when it is 2X or more, the effect is realized well while the forming of uniform multi-axial orientation becomes difficult generally when it is more than 20X. The thickness of the sheet should be 1mm or less and is preferable to be 10Xm-0.5mm.

Abstract: PROBLEM TO BE SOLVED: To detect both ram pressure and atmospheric pressure with one sensor. SOLUTION: Pressure upstream (air intaking side) than an air cleaner in an engine intake passage is detected with a pressure sensor, moderating value Pav of the pressure sensor is calculated after moderating (steps 101, 102). Next, from throttle aperture, engine speed, gear position, and car speed, whether present running condition is in ram pressure correcting region or atmospheric pressure correcting region (that is, whether the pressure sensor moderating value Pav is regarded as ram pressure or atmospheric pressure) is judged, when it is in the atmospheric pressure correcting region, atmospheric pressure correct factor is calculated regarding the pressure sensor moderating value Pav as atmospheric pressure, and when it is in the ram pressure correcting region,  ram pressure correct factor is calculated regarding the pressure sensor moderating value Pav as ram pressure (steps 103-105). After calculating the standard injection time TP, various correct factors, and invalid injection time TV, final injection time TI is calculated (steps 106-109).
