Title: Image density adjusting device in copying machine
Inventor: MAEDA KAZUHIKO
IPC: G03G21/00
Filed: 1987-10-19
Abstract: PURPOSE:To prevent the generation of background fogging in a part of high density even in case of an original sticking a sheet of high density to the mount of a white ground by determining the original density which becomes the basis for an image formation control so as to become higher than an average density of the original density brought to sampling with respect to the document which becomes an object. CONSTITUTION:In the process for scanning optically the original 1, the density in each part of the original which becomes an object is brought to sampling, a mean value calculating means 2 calculates the mean value DDO of the density DD brought to sampling, and also, an original density determining means 3 determines the sampling density DDs being in the vicinity of the mean value DDO at a higher density side than the mean value DDO. This density DDs is used as the background density and image forming conditions, for instance, the electrification quantity, the exposure quantity and the developing bias are controlled. In such a way, when the document in which a background part of high density exists like a dot on a white ground is an object, the image forming condition is controlled, based on the density near to this background part of high density, and background fogging in the part of high density can be prevented.

Inventor: ONO SHINJI
IPC: H03H7/20
Filed: 1985-11-20
Abstract: PURPOSE:To vary minutely the phase with simple circuit constitution by providing a CW oscillator branching a Constant Wave signal into two, a 90 deg. branching filter branching the one branched signal by 90 deg. and a CW variable phase shifter changing the phase of the other branched signal branched by the CW oscillator. CONSTITUTION:The CW (Constant Waves) oscillator 11 branches the CW signal into two. The 90 deg. branching filter 12 comprising a hybrid circuit branches one branched signal by the CW oscillator 11 by the phase of 90 deg.. Further, the CW variable phase shifter 13 varies the other branched signal by the CW oscillator 11. Mixers 14, 15 multiply a signal from the 90 deg. branching filter 12 with a signal through the CW variable phase shifter 13. Low-pass filters 16, 17 extract only a DC component among the signal from the mixers 14, 15 and control multipliers 19, 20 by using the component. The band signal phase shifter constituted as above varies the band signal to an optional phase continuously.

Title: Liquid crystal plate sun visor for vehicle
Inventor: NARITA KOJI
IPC: B60J3/04
Filed: 1988-10-18
Abstract: PURPOSE:To interrupt solar radiation automatically by driving a crystal plate with the power of a solar battery to change a liquid crystal plate sun visor opaquely when solar radiation onto the face of a driver is detected with the liquid crystal plate sun visor set. CONSTITUTION:When a liquid crystal plate sun visor 2 is set in a cabin inside a frontshield window glass 7 by a driver, a switch 4 for a photo sensor 5 is turned on. The photo sensor 5 is so set that it turns on a liquid crystal drive circuit 6 when solar radiation is given at an incident angle to the eyes of the driver. The liquid crystal drive circuit 6 turned on by the photo sensor 5 receives power from a solar battery 3 to drive the liquid crystal plate sun visor 2. The liquid crystal plate sun visor 2 interrupts solar radiation by changing from transparent to opaque one by this driving. Thus the solar radiation given to the eyes of the driver is automatically interrupted and, therefore, the conventional manual operation of the sun visor becomes unnecessary to increase safety in driving the vehicle.

Title: Method and apparatus for frequency hopping spread spectrum power line carrier communication
Inventor: ENDO KAORU
IPC: H04B1/692
Filed: 1985-11-20
Abstract: PURPOSE:To prevent the mutual disturbance between adjacent houses by setting frequencies f1, f2...fn used for the frequency hopping at the transmission side to different values from each house. CONSTITUTION:In the titled method and apparatus, the frequencies f1, f2...fn used for the frequency hopping are set to different values for each house at the transmission side. The frequencies f1-fn used for the frequency hopping are set by providing a programmable frequency divider 8 supplying a clock pulse to a phase comparator 12 provided to a frequency synthesizer 7 at the transmission side while frequency-dividing the pulse and selecting switches 91-9n connected to a control input terminal of the programmable frequency divider. Since the frequencies f1-fn used for the frequency hopping are set differently from each house, even when a frequency hopping spread spectrum modulation signal gives to an adjacent house via a power line 16, no frequency decoding is applied because the reception frequency by the frequency hopping differs from each reception side of the adjacent house, and no effect is given even without a block filter.

Title: Optical soliton transmission method
Inventor: KUBOTA HIROKAZU
IPC: H04B10/508
Filed: 1992-09-30
Abstract: PURPOSE:To stabilize an optical soliton pulse by transmitting a band component of a pulse width and applying intensity modulation to a propagation light synchronously with an original optical soliton pulse period so as to eliminate interaction with a naturally stimulated noise. CONSTITUTION:An optical soliton pulse emitted from an optical soliton pulse generator 11 is propagated through an optical fiber transmission line 13 and the reduction in the intensity by its optical loss is compensated by an optical amplifier 14. After the processing above is implemented repetitively, the optical soliton pulse is stably controlled with an optical filter 15 and an optical modulator 16. Furthermore, after the optical soliton pulse is propagated for a required distance repetitively for a prescribed number of times, the pulse is received by an optical transmitter 12. A change in the energy of the optical soliton pulse is suppressed and made stable by combining the optical filter 15 and the optical amplifier 1. Furthermore, the intensity modulation synchronously with the period of the optical soliton pulse is implemented to set the optical soliton pulse to the center of modulation frequency.

Title: Control device for exposing time of camera
Inventor: GOTO TETSURO
IPC: G03B9/62
Filed: 1984-12-12
Abstract: PURPOSE:To improve the exactness of exposing time by releasing the detention of the front curtain of a shutter by using the rotating force of a motor, calculating the time for releasing the detention of the front curtain of the shutter from the rotating speed of the motor and determining the timing for releasing the rear curtain. CONSTITUTION:This device is so constituted that the signal S2 for controlling the rear curtain, i.e., the signal for controlling the timing for starting the running of the rear curtain is calculated in the 2nd arithmetic circuit 17 by taking the outputs from a speed detecting circuit 19 for detecting the rotating speed of the reversible motor M for releasing the detention of the front curtain 15A prior to the release and an adjusting means 20 into account and is outputted via a rear curtain control circuit 18. The circuit 18 starts the conduction of the electricity to a magnet for detaining the rear curtain and starts at the same time a timer for the rear curtain upon receiving of the output signal from the 2nd arithmetic circuit 17. The conduction of electricity to the magnet for detaining the rear curtain is thereafter stopped and the rear curtain 15B is released when the timer for the rear curtain attains the value of the output signal from the circuit 17. The exactness of the exposing time is thus improved.

Title: Oscillation circuit
Inventor: UCHIDA KENJI
IPC: H03B5/02
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To secure desired power whose efficiency is high by connecting the open terminals of a plurality of oscillating parts to one another at one point to be common electric potential and synthesizing the same phase output. SOLUTION: This circuit is provided with a plurality of oscillating parts 1-1 to 1-n, a common resonator 2 giving the same phase to them and a common- mode synthetic circuit 3 which connects the output terminals of the parts 1-1 to 1-n with one another and synthesizes their oscillation outputs in the same phase. For instance, in the case of an oscillation circuit provided with the two oscillating parts 1-1 and 1-2, when the node of an open side of the transmission line of the part 1-1 and the node of an open side of the transmission line of the part 1-2 are connected to each other with a signal line giving a common phase, an oscillation circuit having two output terminals are formed.  In such a case, the phases of the two oscillation outputs are always the same because a common voltage exists at a connection point, and voltage amplitude is also the same because the parts 1-1 and 1-2 have the same configuration. The output voltage of the oscillation circuit is doubly increased by combining the output voltages of the two parts 1-1 and 1-2.

Filed: 1989-10-06
Abstract: PURPOSE:To prevent paper sheet from being charred and burnt by sucking the paper sheet on the top plane of a paper sheet carrying belt unit part and permitting the distance between a sensor and the center of a puller roller to be shorter than the length of cassette paper in the running direction. CONSTITUTION:The top plane of the paper sheet carrying belt unit 8 is provided with a small hole, air flow 14 is sucked and the air pressure of a running path is permitted to be lower than the outside air pressure. The paper sheet 2 is always carried to the puller roller 9 side while being sucked to the unit 8 side. The light sensor 10 is brought close to a flash fixing device 7 side of a light shielding cover 11, which is adjacent to the flash fixing device 7. The sensor 10 decides its position so as to permit the distance D, which is the distance between the center of the roller 9 and the sensor 10, to satisfy D<L in order to supervise even when the paper sheet whose shortest length is L is used. Thus, even when the paper sheet is carried by being overlapped, the stop of the paper sheet is detected and the carrying is immediately stopped. Since the paper sheet 2 which is held on to the roller 9 moves in the exit direction, the paper sheet cannot be charred by the fixing device 7.

Title: Flat type cell
Inventor: OKAHISA MITSUGI
IPC: H01M2/02
Filed: 1989-10-06
Abstract: PURPOSE:To prevent a flat type cell from being expanded in thickness after discharge by making up a positive electrode core member out of a metal wire gauze 0.05 to 0.07mm in diameter. CONSTITUTION:In a positive electrode for a flat type cell in which a positive electrode active material 3 is carried by a positive electrode core member 2, the positive electrode core member 2 is made up out of a metal wire gauze 0.05 to 0.07mm in diameter. In general, the metal wire gauze 0.1mm in diameter which is usually available, is rolled so as to be formed into the metal wire gauze 0.05 to 0.07mm in thickness so that it is thereby used as the core member. Even if the positive electrode is expanded owing to the discharge of the cell, the positive electrode active material 3 is accelerated to be deformed in the radial direction, whereas the expansion in the thickness direction is restrained. Thus, the cell is prevented from being incapable of coming out of its mounting position because of expansion of its flat shape after use.

Title: Solid-state image converter
Inventor: EBITANI MASUYUKI
IPC: G21K4/00
Filed: 1990-09-29
Abstract: PURPOSE:To obtain high sensitivity and high brilliancy by making electric field luminous layer with a thin film EL, putting a dotted low resistance layer between EL and a photo-electric layer (PC layer) and making the dots radiate corresponding to the excited part in the PC layer. CONSTITUTION:A transparent base plate, transparent electrode 2, thin film EL (consisting of insulation layer 11, thin film luminous layer 12, insulation layer 13), dotted resistance layer (dot layer) 14, PC layer 6, and back surface electrode 7 are overlayed in order. The dot layer 14 is formed with metals such as Al, Au, etc. by vapourization or spattering on the insulation layer 13 with the thickness desirably about 1 micron putting a dotted mask in between. Thus, the voltage of onset of thin film EL luminescence against the incident light magnitude increases for tens of volts at the dotted part compared with undotted part. This is because, even if the PC layer 6 is excited by the incident light, only the thin film EL layer corresponding to the low resistance parts radiates. Thus the thin film EL layer corresponding to the PC layer 6 pats excited by the incident light image only radiates dot-like, and so a dot-like image is obtained.

Title: Massager
Inventor: TAKAGI YASUYUKI
IPC: A61H7/00
Filed: 1990-09-28
Abstract: PURPOSE:To allow a comfortable and effective massage and achieve a reduction in size and cost by keeping an operating speed constant up to a load in general use, lowering the operating speed according to the increase in load at the time of exceeding this load, and stopping the operation at a preset maximum load. CONSTITUTION:A DC motor is used as a driving source, and the applied voltage is varied according to the motor rotating speed up to a load possible to be applied in general use to conduct a constant speed control. The applied voltage is limited to less than a determined voltage at a load exceeding this, and when it reaches a set maximum load, a current control for keeping the current flowing to the motor constant is conducted. Thus, an optimum speed or desired speed set according to treatment can be made constant, allowing a comfortable and effective massage. When a load over the general load is applied, the operating speed is lowered according to the increase, and at the point of time when it reaches the set maximum load, the operation is stopped so as to prevent the forced constant speed control. Thus, the motor can be minimized and lowered in cost.
