Patent JP-S56140370-A (JP)
Title: Formation of electrostatic latent image
Inventor: NAKAMURA ISOJI
IPC: G03G15/02
Filed: 1980-04-02
Abstract: PURPOSE:To eliminate time delay, production of noise and need for any destaticizing light source and make the apparatus simple by changing over the discharge conditions of a corona discharger for charging between the time when the image region of a photoreceptor passes and the time when the nonimage area passes. CONSTITUTION:The three-layer constitution photoreceptor provided on the surface of a photosensitive drum 1 is uniformly charged to 1,500V by a primary charger 2, thence an electrostatic latent image is formed on the surface insulation layer of the photoreceptor by irradiating the original image simultaneously with charging by a DC corona discharger 3 impressed with -7.5kV. Next, according to the brightness and darkness of the original image, a difference in surface potential is produced by a full surface exposure lamp 4, so that the electrostatic latent image of high contrast is formed. Thence, it is corona-transferred onto transfer paper by a corona discharger 7. The discharge conditions of the corona discharger 3 for charging are changed over between the time when the image region of the photoreceptor passes and the time when the nonimage region passes, whereby the need for any destaticizing light source is eliminated and the apparatus is made simple.

Title: Liquid crystal display element
Inventor: TANUMA SEIJI
IPC: G02F1/133
Filed: 1987-02-25
Abstract: PURPOSE:To obtain gentle transmissivity-voltage characteristics by rubbing an oriented film on at least one of a couple of substrates which are opposite to each other in >=2 different directions. CONSTITUTION:The oriented film 3 on at least one of the couple of glass substrates 1 which face each other across ferroelectric liquid crystal 5 is rubbed in >=2 different directions. Namely, liquid crystal molecules 2 have layer structure and two stable states, and the transition between the states (a) and (b) is caused according to the polarity of an applied voltage. When this layer structure is rubbed in two directions shown by arrows A and B, the local disorder of rubbing is caused, and a stabler fine area in the state (a) and a stable fine area in the state (b) are obtained. Those many fine areas differ in threshold voltage at which the transition from the state (a) to the state (b) is generated, so each area changes in state at a different voltage and the transmissivity- voltage characteristics of the whole become gentle.

Title: Dynamic scheduling system for data drive type processor
Inventor: NAITOU HIROMIKI
IPC: G06F15/82
Filed: 1990-02-22
Abstract: PURPOSE:To optimumly distribute load and to improve the efficiency of a system by providing an asynchronous matching means to match arbitrary tokens, which are not determined in advance, corresponding to an arithmetic processing condition. CONSTITUTION:For a data drive type processor, a token merging part 1, program memory part 2, waiting part 3, arithmetic processing part 4, token branching part 5 and cue buffer 6 are coupled by a turning pipe line 7 and the waiting part 3 is equipped with an asynchronous matching instruction processing part 8 composed of an ignition mechanism 11 and an end mechanism 12. On the other hand, the program memory part 2 stores program modules 9 and 10. The ignition mechanism 11 ignites a data token Td, activation token Ts or supply token Tp in the order of arrival and the end mechanism 12 distinguishes the supply token Tp only for a disabled number shown by the data of an end token Te and sends out an end token Te'. Thus, there is no waiting time in arithmetic and the load can be optimumly distributed.

Title: Apparatus for measuring position of partial discharge generated in cable
Inventor: NANBA KATSUAKI
IPC: G01R31/12
Filed: 1983-03-15
Abstract: PURPOSE:To measure the position of a partial discharge generated in a cable at a high accuracy by memorizing a pulse due to a partial discharge generated therein to perform a computation based on the memory contents. CONSTITUTION:A series circuit of a capacitor 4 and a detection impedance 5 is connected between a core wire 1a and a shielding body 1b of a cable 1. When a high voltage is applied between the core wire 1a and the shielding body 1b, a plurality of pulses due to a partial discharge detected with the detection impedance 5 is memorized sequentially into a digital memory 8 through an amplifier 6. Then, an arithmetic unit 9 detects difference in the arrival time between first and second pulses from the memory 8 to compute the position of the partial discharge generated based on the difference and the propagation velocity of pulses through the cable 1. Thus, the position of a partial discharge generated can be measured at a high accuracy.

Title: Contactless ignition device
Inventor: FUJINO HIROYO
IPC: F02P5/155
Filed: 1984-03-09
Abstract: PURPOSE:To enable the ignition timing of an engine to be automatically controlled always in a delay timing side when the engine is started so as to improve its starting characteristic, by providing a delay timing control circuit at starting in which the operating level of an ignition signal detecting circuit is automatically controlled to the delay timing side in a very low speed range of the engine when it is started. CONSTITUTION:A differentiating circuit, operating at a point of time when a power transistor 31 is turned on and charging a capacitor 17 by a time constant determined by resistors 9, 11 and a transistor 28, saturates the capacitor 17 or continues its charge till the power transistor 31 is turned off, and a transistor 25 comes to be in an operating level as shown by Vref2 in the drawing because a base current is drawn from the transistor 25 by turning on the transistor 28. Then the power transistor 31, being turned off at a point of time for pick-up generated voltage Vp to exceed the level Vref2, generated high voltage to strike a spark in a spark plug, and the ignition timing is delayed by a time (t). Next, the transistor 28 is turned off because the capacitor 17 is discharged if the power transistor 31 is turned off, and the operating level Vref2 of the transistor 25 is reset to an operating level Vref1.

Title: Bevel end welding method
Inventor: KATADA KANJI
IPC: B23K9/12
Filed: 1989-02-23
Abstract: PURPOSE:To prevent weld defects and damage of equipment by detecting contact of a nozzle with a side wall of a bevel end formed on base metal by a touch sensor besides a waveform of a welding current or the welding voltage and feeding back it to an oscillating width of a torch. CONSTITUTION:Since the waveform of the welding current malfunctions by noise and the bevel width is presumed more than the actual bevel width, the oscillating width of the torch 3 becomes excessive. When the nozzle 4 is brought into contact with the side wall 1a or 1b of the bevel, the contact is detected by the touch sensor 10 and a signal is outputted to a controller 8. When the controller 8 inputs the signal that the nozzle 4 comes into contact with the side wall 1a or 1b from the touch sensor 10, it controls so as to narrow the oscillating width. By this method, the weld defects and damage of equipment when the oscillating width of the torch becomes excessive are prevented and welding work is prevented from stopping and welding efficiency is improved.

Title: Deceleration method for hydraulic actuator
Inventor: KOJIMA MAKOTO
IPC: F15B11/08
Filed: 1989-02-23
Abstract: PURPOSE:To enable smooth deceleration by braking a moving body while operating a piston cylinder member by means of pressure of water hammer phenomenon generated upon changeover of a hydraulic circuit at the time of deceleration, and reducing shock. CONSTITUTION:Return oil from a hydraulic motor 5 is separately sent to pipe passages 12, 13 which are branched from a pipe passage 11, through a solenoid valve 7. The oil is then introduced to high and low speed throttle valves 14, 15. Only at the time of high speed operation, the oil is returned from a pipe passage 16 through a two position solenoid changeover valve 17 and a pipe passage 18 to a storage tank 10. A hydraulic cylinder 20 energized in a drawing direction is fixed to a bite holder, a brake pad 2 is installed on a piston rod end, and braking is performed on an inner peripheral surface of a turret upon reception of water hammer pressure generated on the pipe passage 16. It is therefore possible to optimally distribute braking force and back pressure effect, smooth the deceleration in order to reduce shock, soften the pressure of a driving system and reduce cost.
