Patent JP-S6421522-A (JP)
Title: Vector input device
Inventor: SAKO KAZUYA
IPC: G06F3/0488
Filed: 1987-07-16
Abstract: PURPOSE:To improve an input function by adding a function for detecting the size of a substance operating an input plate to a vector input device for inputting the magnitude and the sense of a force applied to the input plate as input elements. CONSTITUTION:Infrared light emitting elements T1-T7 and light receiving elements L1-L7 detect the width of a substance existing in a slightly upper space of the input plate 13. Thereby, modes such as character formation based upon a finger, the holding of an eraser and the tracing of an erasing range based upon 3-4 fingers and paper movement or the like based upon the operation of the whole hand can be identified. The vector pattern such as a character can be decided by detecting the magnitude and sense of a force applied to the input plate 13 by sensors S1-S4. Consequently, many functions such as character input and function specification can be inputted without using a keyboard.

Title: Preparation of cyclohexane
Inventor: YAHAGI RIYOUHEI
IPC: C07C67/00
Filed: 1982-10-09
Abstract: PURPOSE:To utilize expensive hydrogen completely with a small investment in equipment and prepare cyclohexane in high yield, by treating benzene in two reaction zones of a reaction zone with too little hydrogen and a reaction zone with excess hydrogen. CONSTITUTION:Benzene is hydrogenated to prepare cyclohexane. In the process, part (about 10-30%) of the benzene is passed through a vaporizer 6' and then to a reactor 9 which is a reaction zone with too little hydrogen, and most (about 70-90%) of the raw material benzene is passed through a vaporizer 6 and fed to a reactor 7 which is a reaction zone with excess hydrogen and hydrogenated. In the reaction zone 9 with too little hydrogen, the raw material benzene is reacted with a gas separated and discharged from the reaction zone 7 with excess hydrogen at 1-3mol ratio between the hydrogen in the gas and the raw material benzene to give a benzene-cyclohexane mixture. The raw material benzene is reacted with the above-mentioned mixture from the reactor 9 and excess hydrogen in the reaction zone 7 with the excess hydrogen to afford the aimed cyclohexane.

The relation of the magnitudes with regard to the correlation value C-1 at the second point and the correlation value C+1 at the third point is judged by a magnitude-relation judging part 4. The adequate interpolation expression is selected by an interpolation-expression selecting part 5 in correspondence with the result of judgment 4a. A position Ar of the corresponding point to the model in the input image is obtained by the selected expression by using A0, C0, C-1 and C+1 in an interpolation operating part 7.

Title: Interrupting/conducting mos circuit
Inventor: FUJISAWA NAOTO
IPC: H02M7/5387
Filed: 1991-07-19
Abstract: PURPOSE:To improve a commutation at the time of conducting/interrupting a load with a simple circuit configuration by controlling to turn ON other MOS transistor pair by a gate controller within a commutation time of a load current at the time of turning OFF one MOS transistor pair. CONSTITUTION:A gate control circuit 30 simultaneously turns ON, OFF a pair of MOS transistors 11-14 of opposite sides of a bridge circuit 20.

The commutation is accelerated by its low ON resistance to reduce a wasteful current consumption at the time of the commutation, and necessity of using commutation diodes, etc., can be eliminated. That is, in view of the channel conductivity of the transistors 11-14, the transistors 11-14 of the circuit 20 are used instead of the commutation diodes.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To conceal the internal space of a door receptacle and prevent dirt or dust from entering the door receptacle by fitting a fancy board to the opening of the door receptacle via a spring hinge, so that the fancy board is pushed into the door receptacle when a sliding door is housed, and caused to turn for closing the opening, when the sliding door is pulled. SOLUTION: A fancy board 7 of color and material matching the frame material and the finishing material of a door receptacle 6 for housing three sliding doors 3, 4 and 5 used for separating two adjacent rooms from each other, is fitted to the opening 9 of the door receptacle 6 via a spring hinge 8. The fancy board 7 is pushed by the sliding door 3 and housed in the door receptacle 6, when the sliding doors 3, 4 and 5 are housed therein. Also, when the sliding doors 3, 4 and 5 are pulled out, the fancy board 7 naturally turns, due to the action of the spring hinge 8, and closes the opening 9 of the door receptacle 6, thereby keeping the inner space thereof invisible from the outside. According to this construction, the opening 9 of the door receptacle 6 is closed, when the sliding doors 3, 4 and 5 are pulled, thereby preventing the ingress of dirt or dust into the door receptacle 6.

Title: Controller for liquid crystal display voltage
Inventor: YABE YASUSHI
IPC: G09G3/36
Filed: 1993-07-20
Abstract: PURPOSE:To control a lighting voltage and a switching-off voltage of a pixel independently of a power source voltage. CONSTITUTION:A resistor R13 placing in a center among the resistors R11-R15 dividing a liquid crystal display source voltage VEE is constituted of a variable resistor, and by operating the variable resistor R13, the voltages V3, V4 are varied. In such a manner, a bias (b) of a liquid crystal display is varied, and the lighting voltage and the switchingoff voltage of the pixel are controlled easily independently of the liquid crystal display source voltage VEE. Thus, the lowering of the lighting voltage and the switching-off voltage according to the lowering of a battery voltage are prevented, and the lighting voltage and the switching-off voltage are controlled at a low temperature time regardless of the power source voltage, and power loss due to high power source voltage estimating the time when the battery voltage is lowered and a temperature is lowered is reduced.

Title: Ac-dc converter
Inventor: MOGI SHIGERU
IPC: H03K17/08
Filed: 1987-07-20
Abstract: PURPOSE:To protect a thyristor by a method wherein a reactor is formed by a superconductive material, the superconductive material is brought to a superconductive state on a stationary state and loss is prevented completely, and the superconductive material is brought to a normal conductive state when a surge intrudes and operated as the reactor. CONSTITUTION:An AC-DC converter has thyristors 1, a module 2, a potential coupling line 5, a current input line 3 and an output line 4, and superconductors 8 are bonded in parallel with reactors 7 at both ends of the thyristors, thus shaping a protective device. Consequently, currents do not flow through the reactors 7 under the state in which the conductors 8 juxtaposed to the reactors 7 are in a superconductive state, thus extremely reducing impedance. When surge currents intrude at one time and exceed the critical currents of the conductors 8 and turn normally conductive, the resistance of the conductors 8 is increased suddenly and currents flow through the reactors 7, and the resistance functions as induced reactance. When surge currents are removed, the conductors 8 are made superconductive again.
