Title: Parameter input device
Inventor: MIYAJIMA AKIHIRO
IPC: G06F3/0354
Filed: 1992-09-02
Abstract: PURPOSE:To detect angle information only by a moving operation without changing a mode by providing two balls which can be basically rotated in all the directions. CONSTITUTION:One ball (a ball 4, for example,) is added to one conventional ball 3 and totally, two balls 3 and 4 are provided. Concerning the newly added ball 4, the information of the rotating direction and rotating amount can be detected similarly to the conventional ball 3. Therefore, when a mouse 1 is not rotated but moved while holding the angle as it is, the information of the rotating direction and rotating amount provided from the respective balls 3 and 4 is completely equal, and a function similar to the conventional mouse is provided. By turning the mouse 1 at all the angles, the angle information can be detected from relative relation between the rotating directions and rotating amounts of the respective balls 3 and 4. Therefore, the angle information can be detected only by the moving operation of the parameter input device without changing the mode.

Title: Wide television signal transmitter
Inventor: YASUMOTO YOSHIO
IPC: H04N5/44
Filed: 1991-09-13
Abstract: PURPOSE:To minimize the signal versus noise ratio and the difference of the processing to see the apparent noise to occur when the processing of the time base compression expansion is performed to a part of the signal to be transmitted. CONSTITUTION:An emphasis 105 is performed to a signal to perform the time base compression at a transmitting side and a deemphasis is performed to a signal to perform the time base expansion at a receiving side.

Title: Program supervisory timer circuit
Inventor: KURIAKI SHINICHI
IPC: G06F11/00
Filed: 1983-12-13
Abstract: PURPOSE:To decrease the scale of circuit by providing a clock gate circuit between a clock generating section and a counter section constituting a supervisory timer. CONSTITUTION:A basic clock waveform a' generated from a clock generating section 11 becomes an input of a counter section 12 via a clock gate section 19 when an output waveform h' of a counter section 12 is at L and frequency- divided. When a frequency-divided waveform b' goes to H, an interruption section 17 outputs a waveform f' to a program operating section 18 and an information transfer section 16 outputs a waveform e' to the operating section 18. The operating section 18 outputs a waveform g' to a supervisory timer clear information transfer section 15 in order to release the cause to interruption by using waveforms f', e' so as to reset the counter section 12. Then the waveform h' keeps L state. If the operating section 18 does not make operation to bring the waveform g' to H state, the counter section 12 is counted up further so as to bring the waveform h' to H state. A gate section 19 inhibits the output of clock at this point of time. Through the constitution, the latch section and alarm output section of the program supervisory timer circuit are not required.

Title: Dado joint router
Inventor: ODA ZENICHI
IPC: B27C5/10
Filed: 1988-09-19
Abstract: PURPOSE:To make the main body of a dado joint router to be reduced in its structure and weight by converting the motor rotation of a single unit to the directional movement opposite to each other at the axial directions of a straight bit and dovetail groove bit. CONSTITUTION:A router 60 holds a Z axial motor 80, and the same diameter cams 75, 76 are rotatably combined thereto parallel to shaft casings 67, 68. The cams 75, 76 are rotated respectively by the motor 80 via a gear train. When the motor 80 is rotated, the cams 75, 76 rotate, the pins 73, 74 engaged with cam grooves 77, 78 are moved respectively to the opposite direction at the same speed and by the same distance. Namely, the rotation of the motor 80 is converted to the coming up and down movement of the direction opposite to each other in a straight bit 82 and dovetail groove bit 84. As the pin 73 is moved upward, the shaft casing 67 also rises, and a spindle shaft 65 moves upward too. At this time, the pin 74 comes down, and thus, a spindle shaft 66 comes down. The vertically directional movement distance of each bit is reduced as a whole, thereby minimizing the apparatus and improving the operability.

Filed: 1993-08-27
Abstract: PURPOSE: To prevent the hollow part of a spacer fabric from being impregnated with paint by applying the specific paint in the state that both layers of the spacer fabric are closely connected with an intermediate web and then removing the restriction of the web. CONSTITUTION: The intermediate web 7 is formed using meltable fibers 6 of hot-melt type based on copolyamide to connect the first and second layers 4, 5 of a velour fabric woven by an industrial yarn such as glass fiber by nailing or tufting. Then the velour fabric provided with the intermediate web is impregnated with a resin and the two layers 4, 5 are mutually stuck to obtain the spacer fabric of a three-layer sandwich structure so that both layers 4, 5 are separated from the web even after making into a prepreg from and the sticking state can be released by heating. When applying a liquid such as paint to the sheet metal connected to the spacer fabric, the application is carried out in a state where the layers 4, 5 are closely connected. Afterwards, the restriction by the web is removed to restore to the original spacer fabric having the hollow part between both layers 4, 5.

Title: Gas detector and gas detecting apparatus
Inventor: UEMATSU SHOICHI
IPC: G01N21/61
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To facilitate the simplification of the constitution of a gas detecting apparatus and the reductions of its size and dissipation power and to detect a plurality of gases by using one pyroelectric infrared sensor. SOLUTION: An Si micro light source 3 emits a detecting infrared light LIR into a gas detecting cell 2. Filter means 4 transmits the light LIR of previously set plurality of absorption wavelength bands. A pyroelectric infrared sensor 5 receives the light LIR transmitted through the means 4 and outputs a detection signal S. Accordingly, it can output the signal S corresponding to the presence or absence of the gas to be detected. Since the source 3 emits the pulse-like detecting infrared light, a chopper and the like are eliminated, reduced in size, and in dissipation power. Pulse power supply means 11 supplies a pulse power to the source 3. Discriminating means 12 discriminates the presence or absence of the gas to be detected based on the output signal S, and hence the presence or absence of the gas to be detected can be effectively and accurately discriminated.

Title: Magnetic head
Inventor: EGAWA MOTOJI
IPC: G11B5/265
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a compatible magnetic head having improved saturation characteristics by suppressing reduction in recorded magnetization. SOLUTION: This magnetic head 31 has a front core 2 and a back core 5 which are formed such that a product of the saturated magnetic flux density (Bf) of the front core 2 and the minimum cross-sectional area Af thereof is larger than a product of the saturated magnetic flux density (Bb) of the back core 5 and the minimum cross-sectional area Ab thereof and a product of the initial permeability (μf) of the front core 2 and the cross-sectional area Af thereof is larger than a product of the initial permeability (μb) of the back core 5 and the cross-sectional area Ab thereof. Accordingly, since the back core 5 is saturated earlier than the front core 2, reduction in recorded magnetization is prevented from occurring, thereby resulting in improved saturation characteristics.  Furthermore, since the saturated magnetic flux densities Bf and Bb respectively have the same values as the conventional ones, it is possible to perform overwriting and achieve compatibility.
