Title: Projector device
Inventor: TAKEUCHI KATSUYUKI
IPC: G02B3/00
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a projector device using a DMD (mirror reflection type optical modulator) capable of converging light on the pupil position of a projecting lens without making a relay lens complicated. SOLUTION: When light radiated from a light source and passing through a rod integrator is guided to a color prism 7 from a relay lens system and separated into the light of three primary colors by a color prism, then is made incident on a DMD 9, a condenser lens 8 is arranged immediately in front of the DMD 9. Thus the light from the projecting lens on a pupil position is converged and the luminance of an image projected on the screen can be improved without complicating the lens system.

IPC: G01R31/302
Filed: 1986-01-09
Abstract: PURPOSE:To make an electron beam direction preventable from going out of order, by installing such a magnetic shielding device as covering both X and Y directional moving stages and motors moving these stages. CONSTITUTION:A magnetic shield plate 31 consisting of permalloy or the like is set up in a lower part of a wafer setting base 19 so as to cover an X direction moving stage 18 and a Y direction moving stage 15 generating magnetism and motors 13 and 16 for driving these stages 18 and 15 tight to this setting base 19. Magnetism to be generated out of these motors 13 and 16 or stages 15 and 18 is intercepted by the magnetic shield plate 31. With this constitution, such an accident that an irradiating direction of electron beams is bent by the magnetism is preventable, thus irregular pitches on an aluminum wiring film formed on a wafer 22 are accurately inspectable.

Title: Tn type liquid crystal display device
Inventor: ISHIHARA SHOICHI
IPC: G02F1/1337
Filed: 1989-01-10
Abstract: PURPOSE:To lower a driving voltage and obtain a large contrast by specifying the angle of intersection of a rubbing process which is carried out for the two substrates of a liquid crystal display element. CONSTITUTION:The angle of intersection of the rubbing process which is performed for the two substrates of the liquid crystal display element is set to >=90 deg. and <=100 deg.. When the angle of rubbing intersection is set to >=90 deg., a threshold voltage shifts to a lower voltage side with its torsional force and the voltage-transmissivity curve of the liquid crystal display element becomes steep. Consequently, a sufficient black display can be made with the same driving voltage as compared with a case wherein the angle of rubbing intersection is <90 in the positive display mode. Consequently, the driving voltage can be lowered and the large contrast is obtained.

Title: Optical information recording member
Inventor: SANAI SUSUMU
IPC: G11B7/243
Filed: 1986-01-13
Abstract: PURPOSE:To obtain an optical information recording member superior in heat resistance, humidity resistance, recording properties, and erasing properties, by providing a thin film structure which is mainly made of Te, Ge, Se, and Pd with a specific ratio of number of atoms of Te, Ge, and Se and a specific value of density of Pd. CONSTITUTION:A recording layer is a composition of a Te-Ge-Se-Pd series, and in a material of the recording layer, the ratio of number of atoms of Te, Ge, and Se is within the area connecting the points A1, B1, C1, D1, and E1 as shown in the figure and the density of Pd is 5-30atom%. An excess Te is fixed as a Pd-Te by adding Pd to a Te-Ge-Se series of high crystallization transition point temperature. Namely, Ge and Pd form compounds of GeTe, PdTe2 and the effect of the compounds results in the enhanced speed of crystallization. Pd forms compounds of Pd2Te and PdTe with Te, and in the Pd-Te series of 50% or more Te density, the compounds of Pd2Te and PdTe have the melting points respectively 740 deg.C and 720 deg.C. It can be considered that the effect of Se lowers the melting point of the film. Therefore, the excess Te can be fixed without changing the melting point of the film of base material of Te due to addition of Pd.
