Title: Receiver
Inventor: TAKAHASHI SATOSHI
IPC: H04B10/60
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent free-running oscillation at the input of a zero signal. SOLUTION: In the case that no optical signal is received from a photodiode, a low level signal Q from a preamplifier is fed to a base of a transistor(TR) 703, a high level signal #Q is fed to a base of a TR 704, and a comparator 508 provides an output of a low level output signal SD. Since the output signal SD from the comparator 508 transits to a low level signal, an output signal from an inverter 10 transits to a high level (voltage is Von ), and a voltage obtained by dividing voltage Von with resistors 102, 707, that is, a voltage of Von ×R2/(R2+R3) is fed to the base of the TR 704, where R2 is a resistance of the resistor 707 and R3 is a resistance of the resistor 102. As a result, a main amplifier 503 provides an output of a low level signal.

Title: Controller for induction motor
Inventor: ICHIOKA TADASHI
IPC: H02P23/16
Filed: 1982-03-25
Abstract: PURPOSE:To always effectively operate an induction motor by providing an amplifier which generates an output of the prescribed gain from when the output current of an inverter exceeds a limiting value and applying the output to the butting points of current control amplifiers in response to the operation mode. CONSTITUTION:When the output current of an inverter 2 is within the limiting value, the output of an amplifier 14 is zero. When the output current of the inverter exceeds the limiting value, for example, at the drive side from this state, the output of the amplifier 14 is applied to the butting points of current control amplifiers 6 through a changeover switch circuit 16 that a switch A is closed under the control of the output of a polarity discriminator 11, thereby correcting the command in the direction of reducing the frequency. When, reversely, at the regenerative side, the circuit 16 is set that a switch B is closed, the output of a polarity inverter 15 is applied to the butting point, thereby correcting the command in the direction of increasing the frequency.

Title: Nonvolatile semiconductor memory device and data reading method thereof
Inventor: YAMASHITA MINORU
IPC: G11C17/00
Filed: 1994-03-18
Abstract: PURPOSE:To normally read out data even when a memory cell is over-erased by detecting electric charge and using a sense amplifier. CONSTITUTION:The information in an over-erased memory cell 11 whose electric charge is discharged more than a prescribed amount by erasing operation, is detected by a detecting means 12. The detecting means 12 outputs a loading changeover signal and inputs it to a changeover means 13. On the other hand, prior to erasing operation, the changeover means 13 is reset by a resetting means 14. Thus, the ability of a sense amplifier 25 is changed over by means of the loading changeover signal. The amplifier 25 reads data out of the erased memory cell 11.

Title: Gun-type burner
Inventor: SHINODA SEIICHI
IPC: F23D11/24
Filed: 1987-03-03
Abstract: PURPOSE:To achieve stable and high burning performance by providing a gap between the rim of an inner cylinder penetration hole and an insulator, and providing a rising part at the penetration hole rim on the side opposite to the direction of air flow into the inner cylinder. CONSTITUTION:The combustion air fed through a duct 19 passes through smoothing holes 12 to enter into an inner cylinder 11, and is mixed with fuel jetted from a nozzle 13. The mixture is ignited by an ignition electrode rod 16 and burns as air is supplied from air nozzles 15 in a stabilizer 14. At the bottom of the inner cylinder 11 there are smoothing holes 12 to evenly distribute the combustion air in the inner cylinder 11 in the circumferential direction. A gap is left between an electrode insulator 17 and the penetration hole in the inner cylinder 11 because of a consideration to avoid an uneven air distribution due to the presence of the electrode insulator 17 which occupies a substantial areal part of the bottom of the inner cylinder 11. The gap is sized large enough to avoid being clogged with dust and others. However, in order to avoid an uneven air flow distribution in the circumferential direction due to too much inflow of air, a rising part 18 is disposed on the side opposite to the direction of the air inflow to increase the flow resistance to reduce the amount of air flow.

Title: Automatic sheet feeding device
Inventor: CHIKU AKIRA
IPC: G03G15/00
Filed: 1987-03-03
Abstract: PURPOSE:To prevent the unsatisfactory sheet feeding or the like, simplify the device, and maintain the stable performance for a long time by connecting a torque limiter to a fractional roller and feeding the sheet tip on a sheet bed between a sheet feeding roller and the fractional roller. CONSTITUTION:When only one original 16 is fed, it is reliably bitten between a sheet feeding roller 18 and a fractional roller 22 and fed. When multiple originals 16 are fed, the friction between the originals 16 is small, thus the rotating force transmitted to the fractional roller 22 is made smaller than the rotation blocking force by a torque limiter connected to it, and the fractional roller 22 is not rotated and stopped. Therefore, the originals 16 on the side in contact with the fractional roller 22 are not fed, and only the uppermost original 16 is fed. Accordingly, the unsatisfactory feeding caused by the abrasion of parts or the turnover or the like of sheets occurring in the reverse roller system is prevented, the device is simplified, and the stable performance can be maintained for a long time.

Title: Optical synchronizing signal extraction system/device
Inventor: KITAYAMA KENICHI
IPC: H04J14/06
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent the sampling of a synchronizing signal extraction system and the discrimination speed of a pulse height value from restricting communication capacity by correlating optical encoding signals with different delays, which are generated in a reception-side, with reception signals by optical correlation detection, integrating the photoelectric signals of respective delays by partial code length and discriminating the pulse height value. SOLUTION: The light reception signal and the light encoding signals with different delays, which are generated on the reception side, are correlation- detected in a 3dB coupler 7 and a balance detector 8. A band pass filter 9 takes out the signals. A square detector 10 execute detection and a partial code length integrator 11 executes integration. Then, a discriminator 12 discriminates the pulse height value. Thus, optical correlation detection is executed. Thus, it is not necessary to execute correlation synchronism between the light reception signal and the optical encoding signals of different delays by using the band pass filter 9 and the square-low detector 10 and a system can easily by constituted. Namely, the division/multiplex transmission system can effectively be executed by extracting the optical synchronizing signal.

Title: Guiding device of unmanned vehicle
Inventor: IIDA YASUHISA
IPC: B62D1/28
Filed: 1982-03-26
Abstract: PURPOSE:To permit an unmanned vehicle to run in a desired course freely without any facility on a ground side by using a rate gyro and sampling and correcting a zero-point error voltage every time when the vehicle stops. CONSTITUTION:The zero-point error voltage VN of the rate gyro 8 generated when the vehicle stops is latched by a latch 24. When a motor 4 is driven and the vehicle starts running, a momentary angular velocity data V(theta,t) is latched by the latch 22. This data contains the zero-point error voltage VN measured right before the actuation, so a subtracter 23 subtracts the zero-point voltage. Consequently, real angular velocity data V(theta,t) is outputted from the subtracter 23 and an angle theta is detected by an integral adder 25. Every time when actuation and stopping are repeated, the zero-point error voltage is latched by the latch 24 and after the actuation, it is subtracted from input angular velocity data to perform integral addition (integration), detecting the attitude angle.

IPC: H01L29/786
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a high-performance highly integrated semiconductor device in which bulk type FETs (insulated gate transistor) and TFTs(thin film transistors) are three-dimensionally integrated. SOLUTION: In a semiconductor device, a first CMOS circuit composed of pinning FETs 11 and 12 and an insulating layer 3 covering the CMOS circuit are formed on a semiconductor substrate 1 and a second CMOS circuit composed of TFTs 21 and 22 is formed on the insulating layer 3. To the active areas 15 and 18 of the pinning FETs 11 and 12, an impurity having a conductivity opposite to that of the substrate 1 is added in the states of stripes extended to a drain area from a source area. The impurity areas deter the expansion of a depletion layer associated from a short-channel effect. In addition, the differences in characteristics, such as the mobility, etc., between the FETs and TFTs are reduced by improving the mobility by using crystallized semiconductor films in which crystal grain boundaries are continuously formed for the island-like areas of the TFTs 21 and 22.

Title: Rotary image pickup device
Inventor: UCHIDA TORU
IPC: H04N5/378
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To simultaneously detect the reading of image information and the position of image information by generating a prescribed pulse in response to a rotary angle of a motor while scanning a line image sensor and outputting an image signal and outputting a read position detection signal in the forward driving. SOLUTION: A line image sensor 2 starts main scanning synchronously with a drive signal ϕ and when a motor 16 is driven forward, a signal from a photo interrupter 12 is sequentially outputted. A read position detection signal E is outputted only when the motor 16 is driven forward by ANDing outputs of circuits 15, 18. A discrimination circuit 20 reads an image signal V in response to the drive signal ϕ received just after the read position detection signal E goes to an H level and outputs a valid signal Ve. Thus, uneven scanning speed of the image signal V is avoided by synchronizing the image signal V with the read position detection signal E.
