Title: Unmanned vehicle
Inventor: FUJINAGA NAOMICHI
IPC: G05D1/02
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide an unmanned vehicle capable of stopping without being deviated from a determined traveling locus at the time of emergency stop and surely stopping in a shorter braking distance. SOLUTION: In the case of immediately executing the emergency stop of an unmanned vehicle concerned based on a prescribed emergency stop command, the unmanned vehicle is urgently stopped while controlling the direction of the vehicle by a traveling control part 31 and a steering driving part 33. Thereby the unmanned vehicle can be stopped at the time of emergent stop without being deviated from a determined traveling locus. The unmanned vehicle is urgently stopped by decelerating a motor 35 for driving the unmanned vehicle at a prescribed deceleration ratio by the control part 31 and a motor driving part 32. When a speed pattern is set up so as to obtain a large deceleration ratio as possible within a range not exceeding the allowable torque of the motor 35, the unmanned vehicle can be stopped in an extremely short braking distance.

Title: Power supplying method for driver
Inventor: NISHIMURA NAOYUKI
IPC: H03K19/00
Filed: 1985-02-21
Abstract: PURPOSE:To reduce the current capacity of a power switch by supplying electric power to an actuating circuit from the power switch and then sending out a signal transmission indication signal to a driver through the actuating circuit, and supplying a signal which indicates an operation state to the C-MOS circuit of a monitor. CONSTITUTION:A NAND circuit 91 is off before the power switch 5 of the monitor 3 is turned on and NAND circuits 41-43 which constitute the driver 4 are disabled, so that signals indicating operation states at respective points B1, B2-B3 are prevented from being sent out. When the power switch 5 is turned on, the NAND circuit 91 becomes able to operate and its output is '0'. The output of an NOT circuit 93 is therefore '1' and the NAND circuits 41-43 are enabled. Consequently, the signals indicating the operation states at B1-B3 are sent out to the C-MOS circuit 6 of the monitor 3 through signal lines 23-25.

Title: Method for driving film semiconductor device, film semiconductor device, and its manufacture
Inventor: HOSODA GOJI
IPC: H01L29/786
Filed: 1995-02-22
Abstract: PURPOSE: To reduce the leak currents of a TFT which is high in field effect mobility by selecting the potential between a source and a drain and the potential between the drain and the source so that the drain current may be flat to the change of potential between the gate and the source without practically changing of the drain current. CONSTITUTION: The ID-VGS property of a polycrystalline TFT is one where the leak current becomes minimum when the potential (VGS) between a gate and a source is -3V or thereabouts, and it increases sharply as VGS becomes larger in negative direction. This is because the width of pn junction between a P-type region and an n-type region which are made in the semiconductor film 203 under a gate electrode 205 and in which Hall carriers exist decreases, and a high electric field is generated, and the leak currents flowing through a trap level increase. When driving a film semiconductor device equipped with such a polycrystalline level, the potential between a drain and a source and VGS are selected so that only the section where the drain current is flat to the change of VGS may be in the specified range. Thereupon, the leak current becomes small.

Title: Photoelectric converter
Inventor: KOMIYA KAZUMI
IPC: H01L27/146
Filed: 1978-03-27
Abstract: PURPOSE: To prevent resolution from lowring by making it possible to screen completely adjacent photo detectors from leaked light flux.  
     CONSTITUTION: Illumination light flux 11 illuminates transmitting original 1 by way of transparent substrate 5, the gap between luminous elements 6, transparent protective layer 8, and photoconductive layer 9. The light reflecting from illuminated transmitting original is diffused from transmitting original 1 in every direction, but almost all of it is acquired by near photodetectors 6 and then converted photoelectrically. Light flux larger in reflection angle among light flux radiated by diffusion propagates in photoconductive layer 9 toward adjacent photodetectors 6, but is total-reflected by groove 10 on its way. This results from the principle that when light propagetes from a medium (conductive layer) higher in refractive index to lower one (air), light flux forming an angle more than critical one is total-reflected. In this way, a photoconductive layer with a groove preventing the diffusion of light is provided in the middle between photodetectors and the transmitting original.

Title: Sound recorder
Inventor: OOTSUBO YOSHINORI
IPC: G11B15/00
Filed: 1983-03-01
Abstract: PURPOSE:To eliminate unstable sound recording in the beginning of a run by detecting that a translucent cleaning leader tape part has passed, stopping the tape run after forming a nonrecording part for several seconds from the passing point of time, and returning a sound recording stand-by state at the same time. CONSTITUTION:A sound recording state is obtained with a sound recording mode switch 7. Then, a tape runs by pressing a switch 8. At this time, when an optical detector 3 detects the state of a sound recordable tape part, the detection signal is inputted to a microcomputer 6. Muting is performed for several seconds from the time of input, thus the tape obtains the nonrecording state. Then, the tape moves and stops and the muting is reset to enter the sound recording stand-by state. Then, when the run mode switch 8 is pressed a gain, a command for the tape run is outputted to enter the sound recording state.

IPC: G03G15/00
Filed: 1991-02-28
Abstract: PURPOSE:To decide the abnormality of a sensor, etc., which are not originally subjected to a diagnosis, as well, in an image forming device which has high autonomy and on which the manpower saving of repairing work is realized. CONSTITUTION:The deterioration quantity from a storage part 15 is read based on a using time up to now and turned into a fuzzy quality value. Then, a parameter value changed by the deterioration quantity is displayed with the fuzzy quality value. On the other hand, state data detected by sensors 1a, 1b, and 1c is turned into the fuzzy quality value, and the presence of the fault is decided with the fuzzy quality value. Consequently, when the fault is absent, the diagnosis of a deteriorated state is carried out by using the parameter value changed by the deterioration value as an initial value. When the fault is absent, and the diagnostic result and the fuzzy quality value of the state data are not in coincidence, a fact that there might be any abnormality, for instance, the abnormality of the sensor, etc., is informed.

IPC: G06Q20/40
Filed: 1989-02-14
Abstract: PURPOSE:To increase the total number of password codes and to make it difficult for a 3rd party to search a password code by storing both a code and its input order together as a password code and collating it with data which is inputted currently. CONSTITUTION:Plural codes and codes consisting of order-predetermined numbers of frames where the corresponding codes are put are inputted in pairs at random and stored as the password code previously. Then it is decided whether or not the currently inputted code consisting of a code and a frame number matches stored password data. Thus, the conception of the frame number is added to the code to increase the kinds of codes. Consequently, this simple constitution makes it difficult for the 3rd party to search the password code.

Filed: 1992-02-21
Abstract: PURPOSE:To make the modulator small in size and to reduce power consumption by providing a polyphase-shift phase modulator and a polyphase-shift amplitude phase modulator in which phase-shift processing is directly applied to a carrier to be modulated and the circuit scale is reduced while keeping the modulation characteristic. CONSTITUTION:A variable phase-generating device 11 generates a carrier whose phase is shifted synchronously with a base band signal. The carrier is phase- modulated by a phase modulator 17 in response to a base band signal with a roll-off waveform whose roll-off is given via a processing unit 15. That is, since the shift processing of a reference phase of the carrier having been implemented synchronously with the base band signal is implemented by the variable phase generating device 11, the roll-off waveform information to be stored in a memory 13 of the roll-off processing unit 15 is enough to be an information based on a single reference phase. Thus, the storage capacity of the memory 13 is reduced, then the addressing required for accessing the memory is simplified, and the circuit scale and power consumption are reduced.
