Title: High polymer optical waveguide and its preparation
Inventor: EGUCHI KUNIYUKI
IPC: G02B6/138
Filed: 1985-03-08
Abstract: PURPOSE:To obtain the titled high polymer optical waveguide having a less photowaveguide loss by irradiating light or electron beam to a substrate in a state of a pattern to form a fine pattern, and by enlarging a difference of a refractive index between a blank part and a reverse mask part according to the refractive index distribution forming method. CONSTITUTION:The transparent prepolymer substrate is prepared by reacting 3wt% BPO and 0.5pt.wt. benzoin ethyl ether to CR 39 in a box type vessel composed of 'Teflon(R)' in an atmosphere of nitrogen. And then, the blank part is prepared on the substrate, and the remainder part is entirely vapor- deposited with a metallic chromium to tightly adhere the reverse mask on the transparent substrate. After exposing the obtd. substrate with a UV ray using a high pressure mercury lamp, the substrate is dipped with methacrylic acid 2,2,2-trifluoroethyl contg. 0.5wt% BPO and heated. After taking out the transparent substrate and curing, the transparent substrate is further coated with a material having the low refractive index using an acrylic emulsion solution, thereby enabling to prepare the titled waveguide having the less photowaveguide loss ad the fine pattern.

Title: Liquid crystal display device, information transmission device having this liquid crystal display device and production of this information transmission device
Inventor: YUZURIHARA HIROSHI
IPC: G02F1/1337
Filed: 1994-02-17
Abstract: PURPOSE:To prevent disturbance in orientation of liquid crystals and deterioration of image quality according to a rubbing defect. CONSTITUTION:TFTs 3 are partially formed on a substrate 2 and an insulating film 9, etc., of the parts where the TFTs 3 are formed (non-opening regions A) are formed to a projecting shape. A PSG film 26 where the parts corresponding to the opening regions B project is formed on the insulating film 9 by an etching back method. Then, an oriented film 12 formed on the PSG film 26 is formed to the projecting shape in the part corresponding to the opening regions B in the same manner as for the PSG film 26. The rubbing is thus well executed. A difference in level between the parts corresponding to the non-opening regions A of the PSG film 26 and the parts corresponding to the opening regions B is made small, by which the liquid crystals 19 arranged in the parts corresponding to the opening regions B are not so much subjected to the influence of the difference in level and, therefore, the liquid crystal thickness is made nearly uniform in the opening regions B.

Title: Vinyl chloride plastisol composition
Inventor: OHASHI YUTAKA
IPC: C08L27/06
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a vinyl chloride plastisol composition which can form a coating film capable of revealing good chipping resistance and sufficient soundproof performance even with a single-layer structure. SOLUTION: A vinyl chloride plastisol composition comprising mainly a vinyl chloride polymer resin, plasticizers and a filler and containing a foaming agent, which contains diheptyl phthalate(DHP) and isononyl phthalate(DINP) as the plasticizers. The coating film obtained from this composition is increased in bulk by the foaming agent and increased in flexibility by DHP and DINP. Therefore, the soundproof performance can be sufficiently improved. Since the coating film is very thick because of the increase in bulk by the addition of a foaming agent, it can well prevent the coated surface from being damaged by, e.g. a small stone piercing the coating film so that it can reveal good chipping resistance.

Title: Method and device for contrasting optical fiber core wire
Inventor: TATSUTA MITSUHIRO
IPC: G02B6/00
Filed: 1987-03-02
Abstract: PURPOSE:To simultaneously confirm the result of contrast of a core wire at a fiber end side and a bending job site, by giving the bending to an optical fiber core wire, propagating a contrast signal light beam and an optical pulse, and photodetecting a radiation light beam from the optical fiber core wire of its bending part. CONSTITUTION:A pulse test light beam, and a contrast signal light beam are generated from an optical pulse tester 8 of a transmitter 7 for core wire contrast, and a contrast signal light source 9, respectively, multiplexed by a multiplexer/demultiplexer 10, and propagated to a contrast optical fiber core wire 2. To its contrast optical fiber core wire 2, bending is given to a fiber bending giving part 4. Subsequently, a radiation light beam from a bending giving part 4 is detected by a radiation light photodetecting part 5, and by a contrast signal receiving discriminator 6, the success of an optical fiber core wire contrast is confirmed. Also, even in the terminal part of the optical fiber core wire 2, the success of a contrast core wire is confirmed from the measurement of the intensity of a Rayleigh scattered light beam. Accordingly, since the contrast signal light source and the optical pulse tester are coupled to the contrast core wire through the multiplexer/demultiplexer, the success of the core wire contrast can be confirmed at a job site for giving the bending and a contrast fiber end, and the efficiency of a core wire contrast work can be improved.

Title: Esd input protective device

IPC: H01L29/78
Filed: 1995-02-10
Abstract: PURPOSE: To protect the input part of a monolithic integrated circuit against ESD(electrostatic discharge) events by a simple structure, by a method wherein a thin film field transistor is broken down before a thick film field transistor, and shunts a fast edge of an ESD transient. CONSTITUTION: When negative ESD events are generated at an input pad, a base-collector junction part formed by a P well 100 and a lateral collector 113 is backward biased. The voltage rapidly increases up to the breakdown voltage of a thin film field transistor collector 113. A hole current A3 generated in this manner flow through a P well base 100 just under an emitter diffusion part 112, reaches a metal layer 118 through a base collector 111, and makes the emitter 112 be forward biased. Thereby the effect is obtained that the rapid rise (fall) of an ESD transient current for which the response of a thick film field device is too late is eliminated.
