Title: Liquid-crystal light valve
Inventor: NAGATA MITSUO
IPC: G02F1/1347
Filed: 1981-08-04
Abstract: PURPOSE:To increase a response speed by providing electrodes for applying a horizontal electric field to liquid crystal at both sides of electrodes which constitute a light valve part. CONSTITUTION:A nematic liquid-crystal layer 11 of twist structure is sandwiched between a couple of substrates 10, and electrodes 13 and 14 constituting a light valve are provided on surfaces of the substrates which face the liquid-crystal layer; and electrodes 15-18 are provided on both sides of the electrodes 13 and 14, and a polarizing plate 12 is arranged on the external surface of a substrate 1. While no electric field is applied between the electrodes 13 and 14, an electric field is applied between the elctrodes 15, 16 and 17, 18 to apply the liquid-crystal layer 11 with the electric field horizontal, and thus a force for turning off liquid- crystal molecules is generated to increase the electric field, increasing a response speed. Consequently, the response speed is high enough for a printer which uses a liquid-crystal light valve array.

Abstract: PURPOSE:To highly stabilize the center frequency of band-pass filter characteristics easily and to change also the band width easily by making the center frequency of the band-pass filter characteristics coincide with the frequency of a reference local oscillator and fixing the band width by the interruption frequency of a low-pass filter.

Title: Sputtering target material
Inventor: TSUCHIYA MITSURU
IPC: C23C14/34
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce particles and sheet resistance value at the time of sputtering and to increase the productivity and yield by controlling the average grain size of the recrystallized crystals in a recrystallized sheet obtd. by subjecting a W/Mo alloy rolled sheet or a W rolling stock to heat treatment to the value equal to or below a specified one. SOLUTION: A W ingot sintered in hydrogen is rolled at about 1300 to 1600 deg.C in such a manner that it is not recrystallized to form into a W sheet. In this way, the W sheet having about 99.9% relative density can be obtd. This sheet is moreover subjected to heat treatment for about 30 min in a furnace heated at about 1700 to 1800 deg.C and is recrystallized. The obtd. recrystallized grains have uniform grain size, and the average grain size thereof is <=100 μm. Furthermore, in the containing gas used, the content of oxygen is controlled to 10 ppm, nitrogen to <10 ppm, and the total is controlled to <=100 ppm. By a target for sputtering using this W sheet, the sheet resistance value of the formed W film remarkably reduces. The generating frequency of foreign matters (particles) generated at the time of film formation exceedingly reduces as well.
