IPC: G02F1/136
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To suppress the production of a smear by constituting so that snake path electric field from a video signal line to a reference electrode is reduced. SOLUTION: A display electrode 18 and the reference electrode 14 are provided on each pixel area on a liquid crystal side surface of transparent substrates arranged each other through a liquid crystal layer, and the electric field parallel to the transparent substrate is generated in the liquid crystal layer by voltages applied to these electrodes, and thus, light transmitting through the liquid crystal layer is modulated. Then, a video signal from a video signal line 3 through a switching element turned on by supply of a scanning signal from a scanning signal line 2 is supplied to each display electrode 18.  In a liquid crystal display element, two lines of video signal lines 3 supplying the video signal to the display electrode 18 in each pixel area are arranged side by side in the direction of y between a pair of pixel areas adjacent to each other of respective pixel areas arranged side by side in the direction of x. Thus, the liquid crystal display element is constituted so that the video signal lines 3 aren't arranged between one pixel area between a pair of pixel areas and another pixel area adjacent to the pixel area.

Title: Amplification type solid-state image pickup element and its driving method
Inventor: UENO TAKAHISA
IPC: H04N5/335
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce the dark currents of picture elements by performing electric charge injection at the interface between the surface of a semiconductor and an insulating film within a required time in a horizontal cycle period at every plurality of horizontal cycle periods. SOLUTION: An occurrence of paired electron-Hall at the interface between the surface of a p-type sensor area 8 and a gate insulating film 9 of a pixel MOS transistor 11 is suppressed by injecting electronic charges (electrons) into the interface within a horizontal effective scanning period in an electric charge storing period, for example, the horizontal cycle period. Namely, the electrons are injected into a channel from a source area 2 or drain area 3, by making at least the source potential or drain potential lower than the channel potential. This electron injection is performed once per plurality of horizontal cycle periods. Therefore, the dark current caused by the interface can be suppressed and, at the same time, the occurrence of the dark current which is generated when a channel current flows can be suppressed by preventing the flow of the channel current.

Title: Gate valve for car antilock system
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/42
Filed: 1984-11-02
Abstract: PURPOSE:To keep off high pressure action on an accumulator as well as to aim at miniaturization as a whole, by intercepting a transfer route when input system hydraulic pressure goes up beyond output system hydraulic pressure, while using a gate valve which lets return hydraulic pressure out of the accumulator escape to the input system when it exceeds the specified value. CONSTITUTION:In time of antilock control, an output system main route 2 is intercepted from an output hydraulic chamber B by open close selection of a first valve 3, and brake hydraulic pressure inside the main route 2 is made to go down by close open selection of a second valve 6. In addition when this pressure oil is pumped up into a return oil chamber D from an Acc 9 by a pump 8, a balance piston 11 moves to the left, making a valve body part 12 come into contact with a valve seat 13, whereby interconnection between both input and output hydraulic chambers A and B is cut off. With this interception, the output hydraulic chamber B is separated from the master cylinder side in terms of pressure by a gate valve 4, and the pressure oil pumped up via a bypass passage 5 is not transmitted to the master cylinder side so that a kickback phenomenon in a brake pedal may not happen there. Therefore, an accumulator can be miniaturized, preventing a hydraulic lock from occurring, and no high pressure is received.

Filed: 1988-09-16
Abstract: PURPOSE:To manufacture a molding mold with an excellent mold releasing property and defoamability in less expensive by giving an emboss configuration to anti-soluble plastics having specific value or less in its soluble parameter and specific value or more in its elongation in the breaking point. CONSTITUTION:Olefin or fluoro resin such as polymethylpentene, polyethylene, polypropylene or the like can be used as anti-soluble plastics. Since the solubility parameter delta of high polymer to be a lens sheet material is in the region of 9.0-10.0, should the high polymer having solubility parameter delta of 8.0 or less be employed as high polymer to be a molding mold material, it may be preferable in its mold release. A flexible material is not susceptible to be damaged in its sheet upon releasing the molded sheet from the molding mold, therefore, the flexibility is provided. In consideration of the breakage of ionizing radiation curing resin or mold releasing failure, it is desirable that the elongation of a breaking point is 70% or more.

Title: Synchronising circuit
Inventor: ADACHI HIROSHI
IPC: G06F13/42
Filed: 1984-11-05
Abstract: PURPOSE:To synchronize asynchronous external signals and minimize the delaying time at the time of synchronization, by providing two parallel transparent-type latches and an OR circuit at the preceding stage of an FF for synchronization. CONSTITUTION:Signals from a bus B are received by a receiver R1 and inputted in latches L1 and L2 as asynchronous external signals S1 at a certain timing. Since the latches L1 and L2 are of transparent type, their output signals S21 and S22 change following the signal S1 after a holding time has passed. Similarly, the signal S23 of an OR circuit changes after delaying by the delay time of the OR circuit. At the rise of a synchronizing clock C, the latches L1 and L2 latch the signal S1 and do not make any response even when the signal S1 changes at the rise of the next pulse. As a result, a synchronizing FF F1 sets the stable signal S23 at the rise of the pulse of clock C, and thus, a signal S2 which is completely synchronous to the clock C can be generated.

Title: Alarm sound generating device
Inventor: OWA YOSHIHITO
IPC: G04C21/16
Filed: 1985-10-18
Abstract: PURPOSE:To exactly hear alarm sound by constituting the titled device so that an alarm signal of a frequency which has been separated farther from a frequency of a sound of the periphery can be selected. CONSTITUTION:An output is generated from a terminal (q) of a detecting circuit 5, and a frequency detecting circuit circuit 7 operates and detects a frequency of a sound of the periphery. In case a sound of a frequency which is higher than a frequency (fA+fB)/2 has been detected, an output of a selecting circuit 8 becomes '0' and a gate circuit 9 is selected. When the remaining time becomes '0', an output is generated from a terminal (p) of the circuit 5, an alarm signal of a frequency fB is supplied to a sounding device 13 through the circuit 9, and the alarm sound is generated. Also, when the sound of the periphery is lower than the frequency (fA+fB)/2, a gate circuit 10 is selected by the circuit 8. Accordingly, when the remaining time has become '0', an alarm sound is generated by an alarm signal of a frequency fA. In this way, the alarm signal of a frequency which has been separated farther from a frequency of the periphery is selected, therefore, the alarm sound can be heard more exactly.
