Title: Semiconductor device
Inventor: TSUBOI TOSHIHIDE
IPC: H01L21/8238
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To suppress and reduce the increase of chip size without marring the resistance to electrostatic breakdown and latch up, by arranging a MOSFET where a source and a drain are not connected to power or ground, between n-channel and p-channel MOSFETs. SOLUTION: For p-type MOSFETs 510-512, and 514, the drains are connected to external i/o terminals, and the gates and the sources are connected to ground. For n-type MOSFETs 515-517, and 519, the drains are connected to external i/o terminals, and the gates and the sources are connected to the power source. The p-type MOSFETs 511 and 512 where the sources are not connected to ground and the n-type MOSFETs 515 and 516 where the source are not connected to ground are arranged between the p-type MOSFET 514 and the n-type MOSFET 519.

IPC: G02F1/1333
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an electro-optical device such as a liquid crystal device which is high in contrast and bright in display by reducing the alignment irregularities of electrochemical substance due to a step difference of a substrate surface and the alignment irregularities of the electro-optical substance due to a transverse electric field. SOLUTION: In the electro-optical device, a resist mask is formed on a TFT array substrate 10, and thereafter, an etching is performed in an etching gas environment containing oxygen, thereby, the resist mask is subjected to the etching and, at the same time, the surface of TFT array substrate 10 is subjected to the etching. As a result, a recessed part 201 which has a side surface part 202 which is a tapered surface is formed on the TFT array substrate 10 and, therefore, the region where data lines 6a are formed is flattened. Also, since in the TFT array substrate 10, a projecting part 301 which has a side surface part 302 which is a tapered surface is formed, in this region, a liquid crystal layer is made thin and the longitudinal electric field is strengthened, and the effect of the transverse electric field is suppressed.

Title: Power saving lcd drive system
Inventor: IGARI SHOJI
IPC: G02F1/133
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce drive power of an LCD display device by constituting so as to stop a through current flowing between MOS transistors when a common voltage or a segment voltage is switched. SOLUTION: One side of an LCD cell C11 is connected to a segment line through electrode resistance R0, and the other side is connected to a common line through the electrode resistance R0. When the voltage applied to the LCD cell 11 is switched, a MOS transistor SDM 14 is switched from on to off, and the MOS transistor SDM 12 is switched from off to on. When this switching is performed, though the period when the MOS transistors SDM 12, SDM 14 are turned on simultaneously exists, since a switch S32 is turned on, and the switch S34 is turned off, the through current doesn't flow between the MOS transistors SDM 12 and SDM 14, and only i1 flows. Further, the penetration current doesn't flow between the MOS transistors CDM 11 and CDM 13, and only i2 flows similarly.

Title: Apparatus for adjusting working fluid pressure
Inventor: HERUBERUTO BURENDEINGAA
IPC: E02F9/20
Filed: 1992-12-07
Abstract: PURPOSE: To simplify pressure adjustment in a hydraulic device and to minimize loss in pressure adjustment. CONSTITUTION: The apparatus has a comparator 25 which compares the predominant present actuator pressure with a target or desired control pressure for the control valve 2 which regulates the actuator pressure, and generates a signal for re-adjustment of the control valve using the pressure differential. As the control pressure for the control valve provides a measure for pressure adjustment, and the adjustment signal from the comparator overlaps the control pressure directly acting on the control valve, pressure adjustment without loss can be achieved without necessitating discharge of a large amount of working fluid into a tank. Thus, a pressure valve for adjustment of working pressure can be completely eliminated.

Abstract: PURPOSE:To twist wires in one process and to shorten working time by arranging a mandrel having spiral-shaped groove, which an element wire is guided as winding state, and rolls for adjusting shape of the element wire shaped with this mandrel between the mandrel and a twist hole. CONSTITUTION:By passing the element wire 2 through the mandrel 24, the spiral-shape is remained in the element wire 2.
