Inventor: SEGAWA HIDEO
IPC: G02F1/055
Filed: 1981-11-11
Abstract: PURPOSE:To form an optical switching array which can be driven with a low voltage and as a high contrast, by forming a common electrode or individual electrodes on a substrate as prescribed. CONSTITUTION:A pair of grooes 14 and 15 having a depth D are formed a proper length apart from each other in parallel on the surface of a substrate 10. A common electrode 12 and individual electrodes 13 are so formed that a pair of wall faces 16a and 16b facing each other of a wall part 16 between grooves 14 and 15 are partial forming faces of these electrodes. In an optical switching array formed in this manner, the effective depth of the electric field generated in the thickness direction of the substrate 10 depends upon the depth D of grooves, and the depth D is set to a proper value to set easily the effective depth of the electric field to a desired value. Thus, the optical switching array which can be driven with a low voltage and has a high contrast is formed.

Filed: 1983-09-28
Abstract: PURPOSE:To keep threshold voltage and to reduce the number of transistors (TRs) by connecting a signal boosting capacitor between the source of a signal transmitting TR and the drain of a signal transmitting TR in the succeeding shift register to store a signal temporally. CONSTITUTION:Four-phase clocks phi1-phi4 are square wave clock signals delayed by 1/4 period phase successively. When an input signal S10 is impressed at time t0-t1, a signal transmitting MIS TR Tr1 is turned on because the clock phi1 is in the H state, and a signal storage capacitor C1 and a signal boosting capacitor C5 are also charged up to VDD-VTH. At the time t1-t2, the clocks phi1, phi2 are turned to the H state and the input signal S10 is turned to the L state, so that a signal storage capacitor C2 and a signal boosting capacitor C6 are charged up to the VDD-VTH. In a series circuit operation, the input signal S10 is delayed by the phase delay time of the four-phase clocks phi1-phi4 and outputted as a signal S11.

Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To clearly view displayed content and to turn off a backlight in the case it is unnecessary to view the display so that power consumption is saved and the life of the backlight is prolonged by providing a manual switch for turning on/off the backlight illuminating a display part from the back surface. SOLUTION: When the manual switch 4 is depressed by an operator, a control part 13 turns on a switching part 11 to light the backlight 12, and simultaneously a timer 14 starts time measuring for a specified time. Thus, the liquid crystal display part is illuminated by the backlight 12 from the back surface and the operator clearly views the content such as set temperature or remaining hot water quantity in a bathtub displayed on the liquid crystal display part even when a remote controller is set in a dark place. Since the backlight 12 is surely turned off when the specified time elapses even in the case the operator forgets to press the switch 4 in order to turn off the backlight 12, the power for lighting is saved and the life of the backlight 12 is prolonged.

Title: Signal level switching circuit
Inventor: TAKAHASHI TOSHIICHI
IPC: H03H7/24
Filed: 1994-07-09
Abstract: PURPOSE:To surely switch a signal level by turning off a bipolar transistor by impressing a prescribed voltage through 4th and 3rd resistors to the collector of the bipolar transistor. CONSTITUTION:When an IF band is WIDE, a system controller turns a signal level switching control signal VCNT to about 0V and turns off a bipolar transistor TrQ. At this time, since a positive voltage +B is impressed through 4th and 3rd resistors R4 and R3 to the collector of the TrQ, collector/base connection can be turned to a reverse bias state, and the TrQ can be surely turned off. Even when a little cutoff current flows from the collector to the base, that current flows through a 5th resistor 5 to the ground so that the TrQ can be completely turned off. As a result, the signal level switching circuit can be provided to surely switch the signal level while reducing the burdens on the configuration and cost.

Title: Solid-state color image pickup device
Inventor: SEKINE KOICHI
IPC: H01L27/14
Filed: 1986-07-31
Abstract: PURPOSE:To prevent a scattering of resist coating from occurring and to prevent picture quality from being deteriorated caused by color shading, by forming a film of the same thickness so as to surround projecting patterns. CONSTITUTION:On the periphery of projecting patterns 31 on a peripheral region 2, a film 32 of the same thickness as this projecting patterns is formed so as to surround the projecting patterns. This formation is facilitated by using the same materials as follows: if the projecting patterns 31 are made of aluminium, the film 32 is also made of aluminium, and if the patterns 31 are made of polycrystalline silicon, the film 32 is also made of polycrystalline silicon. Since no step difference in the patterns is thus generated in the projecting patterns 31 caused by the film 32 formed on the periphery of them, a scattering of resist coating does not occur regardless of the position where the projecting patterns 31 exist.
