Title: Production of grid polarizer
Inventor: YASUMA YASUHIRO
IPC: G02B1/115
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To produce a grid polarizer having a good polarization characteristic with good reproducibility by making it possible to exactly and surely detecting the end point of etching with an inexpensively system at the time of producing the grid polarizer by dry etching. SOLUTION: The metallic grid is formed by depositing a metallic film on the antireflection film of a light transparent substrate provided with the antireflection film on its front surface, providing the surface of the metallic film with a striped mask arrayed with wire-shaped patterns in parallel at equal intervals and dry etching the metallic film. While a workpiece 32 is rotated by a substrate rotating and holding section 34, the dry etching is executed by an argon ion beam etching method using an ion gun 36. The metallic grid forming surface of the workpiece is irradiated with linearly polarized light by a laser device 40 during this time. The intensity of the light transmitted through the workpiece is monitored by a photodetector 42, by which the polarization characteristic is evaluated. The end point of the dry etching is then determined and the etching work is ended.

IPC: B21C1/04
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a metallic wire homogeneous and most suitable for precision working so as to suppress dispersion of free length when formed for a spring or so by limiting an amount of twist of metallic wire between the front and rear of a die at the time of wire drawing to a prescribed value or lower. SOLUTION: When a metallic wire is drawn by a die, an amount of twist of the metallic wire is <=20 deg./100 mm between the front and rear of the die. When continuous wire drawing is executed with a plurality of dies, the amount of twist of the metallic wire between the front and rear of the last stage die is <=20 deg./100 mm. When continuous wire drawing is executed with n pieces of dies, and the amount of twist per 100 mm between the front and rear of each of the dies are θ1, θ2...θn respectively, Σθn is <=130 deg.. As to the metallic wire, carbon steel wire is cited, and above all spring steel wire is the suitable.  In order to decrease the amount of twist-when the wire is made to pass through a die, the directional condition is adjusted to get rid of generation of twist: the uneven wear of dancer roller used when the metallic wire is transferred from a coil drum to anothetr coil drum is made to decrease: and eccentricity of the coil drum is removed: such and such are cited.

Title: Driving method for liquid crystal display device
Inventor: MAEKAWA TOSHIICHI
IPC: H04N5/66
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent the quality of a display picture from being degraded even in the case of the small size of an element by supplying such potentials as to make the change amount of a picture signal smaller which is to be supplied to first signal lines before supplying the picture signal to the first signal lines. SOLUTION: When the video signal of all whites (or all blacks) is supplied to an input terminal 1 and driving pulse signals ϕH1 ∼ϕHm are supplied to switching elements M1 -Mm , a horizontal blanking pulse HBLK is supplied to a reset terminal 5 and then the switching elements M1 ∼Mm are turned on. Consequently, potentials of respective lines L1 ∼Lm are recharged to a target voltage in the periods of respective horizontal blanking pulses HBLK and moreover the potentials are changed from the target voltage to the potential of the video signal. Thus, in the driving method of this liquid crystal display device, a signal to be changed in one pulse period of the pulse signals ϕH1 ∼ϕHm becomes a maximum of Vp and the change amount of the signal is made half that of a conventional device.

Title: Solid-state relay
Inventor: NOBE TAKESHI
IPC: H01L33/00
Filed: 1992-12-10
Abstract: PURPOSE:To provide a solid-state relay in which only an input current of a prescribed limit flows with respect to a wide range of input voltage by connecting a depletion MOSFET whose gate and source are short-circuited via a resistive component in series with a light emitting element. CONSTITUTION:When a voltage is supplied between input terminals 6a and 6b, an input current flows via a resistance component 5. Thus, the gate of a depletion DMOSFET 8 is biased to a negative voltage with respect to a source by a voltage across the resistance component 5. An input current to the DMOSFET 8 is limited by the bias voltage. Thus, only a current of a prescribed limit flows to the light emitting element 1 against a wide range of input voltage in the voltage versus current characteristic between the input terminals 6A and 6B of the solid-state relay.

As a result, movement transmitted to the work piston 4 by the cam 2 is transmitted to the valve 1 via the stroke piston 8 or is interrupted. Therefore, movement of the valve 1 can be opened from movement constrained by the cam 2.
