Abstract: PROBLEM TO BE SOLVED: To obtain a novel optical operation which is excellent in operability and with which high-speed optical computing is possible with a simple structure by building and integrating polarizers, an optical rotatory dispersion element and a nonlinear optical element having a cubic or higher nonlinear optical effect to a flat plate form. SOLUTION: The polarizers 13, 16, the optical rotatory dispersion element 14 and the nonlinear optical element 15 having the cubic or higher nonlinear optical effect are integrated and formed to the flat plate form. The polarizers 13, 16 are commercially marketed polarizing plates formed by holding polarizing films provided with dichromaticity with glass plates, when an example thereof is shown. The optical rotatory dispersion element 14 is formed by doping dimethyl hexahelicene to polymethyl methacrylate(PMMA) and forming a cast film on the polarizing plate 13. The nonlinear optical element 15 is formed by doping cyanine dyestuff to the PMMA and forming a cast film on the polarizer 16. The rugged parts in the peripheral parts of the respective cast films are removed and the flat surfaces are stuck to each other by an optical adhesive.  At this time, the adhesive having the refractive index approximate to the refractive index of the PMMA is used in order to prevent the disturbance of polarized light on the adhered surfaces.

Title: Multicolor display control system by color lcd
Inventor: NAKAMURA YUJI
IPC: H04N9/12
Filed: 1990-08-18
Abstract: PURPOSE:To accomplish multicolor display by driving a color LCD by three bits of GRB based on the four bits of display data of GRBI and performing white mixture by supposing that GRB in the case of I=1 between frames is set at GRB=111 (m) times per (n) times(n>m). CONSTITUTION:An I bit decision part 2 decides as to the four bits of display data of GRBI which is inputted. When I bit=0, GRB is taken as LCD display data as it is, and when I bit=1, a frame thinning and white mixture generation part 3 is informed of the effect, then GRB is taken as LCD display data which is replaced by GRB=111 at the rate of (m) times per (n) times(n>m) between the frames. Otherwise, GRB is taken as the LCD display data as it is and a color LCD 5 is driven to perform display based on the LCD display data of GRB from the decision part 2 or the generation part 3. With such constitution, the multicolor display is accomplished without lowering brightness.

Title: Build-up welding method for copper or copper-based alloy
Inventor: HATTORI KAZUNORI
IPC: B23K35/30
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent an intergranular intrusion of a copper alloy into a base material by previously forming a layer in which a ferrite structure is preserved in a temperature range between a solidified temperature and room temperature on the surface layer of a base material composed of a steel material and coating the surface of the layer with copper or a copper alloy. SOLUTION: Preferably, a layer in which a ferrite structure is preserved in a temperature range between a solidified temperature and room temperature is formed on the surface layer of a base material composed of a steel material by a built-up welding, and the previously formed layer in which a ferrite structure is preserved is a ferritic stainless steel. In a case where the metallographic structure of a steel material in contact with a melt copper alloy heated to a high temperature by a welding arc is austenite structure, an intergranular intrusion takes place, and in a case where the metallographic structure is ferrite, the intergranular intrusion does not take place.  Thus the intergranular intrusion is effectively prevented when a molten metal layer is formed on a base material of a different kind of metal in such a case where copper and a copper-based alloy are welded on a various kinds of steel materials by a built-up welding. An acquired member is, therefore, a composite material member resistant to a high load.

Title: Arm-worn instrument
Inventor: KAMIMOTO TAKASHI
IPC: A61B5/0245
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To make capable of eliminating body movement noise, sensing without being strongly pressed, overcoming the influence of a temperature change and withstanding long sensing by providing a pulse wave sensor that detects displacement of a skin surface due to pulse waves and that measures continuously a time interval between pulsations. SOLUTION: When an arm-worn instrument is to be mounted on the wrist with a mounting band, it is closely contacted and fixed so that spheres at the lower ends of columnar projections 37 may always contact the skin. Of many columnar projections 37, one moves upward due to a pulse, a displacement sensor 35 is strained and can sense a pulse wave. In other words, raised by skin displacement due to pulsation, the upper ends of the columnar projections 37 press the displacement sensor 35, producing a strain. This strain is converted to an electrical signal with the displacement sensor 35 which can sense a pulse wave. Cataplectic heart disease such as cardiac infarction can be predicted by processing signals of this pulse wave sensor and recording a time interval of pulse waves for many hours, and analyzing the fluctuations with a signal processing section.

IPC: G02F1/136
Filed: 1990-08-22
Abstract: PURPOSE:To prevent a chromium wire from breaking by varying the width of an electric conductor at a connection part between a chromium terminal and the electric conductor in the liquid crystal display panel of a thin film electronic circuit which includes the aluminum electric conductor whose surface is coated with an anodic oxide film, the chromium terminal, and a transistor. CONSTITUTION:The aluminum electric conductor 12 is made narrow so that anode oxide liquid is stopped when entering the connection part between the Al electric conductor part 12 and Cr terminal part 11 from the step between a photoresist film 21 and the Al electric wire 12. The Al electric conductor width 23 is varied so that a crack generated in the photoresist film 21 along the step does not reach the Cr electric conductor part. Consequently, the entry of the anode oxidizing liquid in anodic oxidation and an accident of the fusion of the Cr electric conductor due to the entry resulting from the cracking and adhesive strength of the photoresist can be prevented, so the reliability of the electric conductor is improved to improve the yield.

Abstract: PURPOSE:To eliminate the transverse position shifting of an original which occurs during paper feed and to stabilize the position relation between effective photoelectric scanning width and original width by supplying an original continuously from an original supply roll to an image read part and making the effective photoelectric scanning width smaller than the original width. CONSTITUTION:The original 14 is always set on an original platen 16 and the image reading part 11 through a platen 13 and fed continuously from the original supply roll 15. When characters, graphic forms, etc., are written on the original 14 on the original platen 16 by handwriting, the platen roller 13 sends the original 14 in a direction D2 and the image is scanned by the photoelectric transducer array 12 in the image reading part 11 and outputted as a one-line image signal. The feeding of the original and the photoelectric conversion scan are repeated to read the whole image. At this time, the effective photoelectric scanning width S2 of the image reading part 11 is a little bit smaller than the original width M2. Further, the original 14 is so set that said effective photoelectric scanning width S2 is in the center of the original M2.
