Title: Shieldless balanced couple-type cable for high speed digital signal transmission
Inventor: KUSAKA SHINJI
IPC: H01B11/00
Filed: 1994-08-09
Abstract: PURPOSE:To improve conversation leakage preventive properties and make a shieldless balanced couple-type cable usable for a multi-coupled cable for high speed digital transmission by coating coupled stranded wires with a tape- like material having dielectric tangent tandelta 1X10<-2> or higher and dielectric constant epsilon2.5 or higher. CONSTITUTION:Since a tap to coat coupled stranded wires 1 has 2.5 or higher dielectric constant e, an electric field generated in the coupled stranded wires 5 is converged in the tape 7. Also, since the tape has dielectric tangent tandelta 1X10<-2> or higher, the conductance of the tape 7 becomes high and leakage los occurs in the tape 7. As a result, the shielding effect of the coupled stranded wires 5 is heightened and the effect of coupled standed wires on other coupled stranded wires becomes slight and thus conversation leakage preventive properties are improved. The cable can be produced by using a plasticizer or flame retarding agent with high conductivity or a compound produced by mixing a magnetic powder with polyolefin or alloying them as a means to provide high dielectric tangent tandelta and high dielectric constant epsilon.

Abstract: PROBLEM TO BE SOLVED: To prevent degradation in film adhesion, film fatigue characteristics, and polarity holding characteristics caused by stress, for improved reliability, by using a compound comprising platinum element as an electrode. SOLUTION: The surface of a silicon substrate 101 is oxidized to form an insulating layer 102, over which titanium is used as an adhesion-strengthening film 103 against an electrode, then platinum as an electrode material, and the target of (Pb(ZrxTi1-x)O3) as an dielectrics material, to form one electrode 104 of a capacity element (a lower part electrode) and a dielectrics film 106. Here, by changing an RF power applied to a platinum target and PZT target, a composition transition region 105 wherein the ratio between platinum and the PZT constituting the dielectrics film 106 continuously changes is formed, and a specified pattern is formed as a remaining one electrode 107 of the capacity element (an upper part electrode).

Abstract: PURPOSE:To measure the concentration of sludge accurately by providing a means to calculate the mean brightness of a sludge region and a liquid region based on an image signal for treatment water and a digitized image from an activated sludge recognition means, and to calculate the concentration of sludge in treatment water through correction of the area or volume of a special microcalculation means on the basis of said mean brightness. CONSTITUTION:A treatment water image is sequentially photographed by means of a submerged camera 11, and this image signal is digitized by an activated sludge recognition means 30 to separate and extract an activated sludge region and a liquid region in treatment water. At the same time, the volume of sludge is obtained using the area of the sludge region. Next, the mean brightness of the sludge region and the liquid region is calculated by a brightness calculation means 60 based on an image signal from the submerged camera 11 and a digitized image from a recognition means 301. On the basis of this mean brightness, the sludge volume of the activated sludge recognition means 30 is corrected and an effluent sludge concentration in the treatment water is calculated by a sludge concentration calculation means 100. In this way, a surplus sludge amount discharged outside of a system is controlled based on a sludge concentration obtained regardless of the shape and grain size of activated sludge and the color of treatment water.

Title: Liquid crystal display element
Inventor: TABATA SHIN
IPC: G02F1/1343
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To adjust an angle of visibility in accordance with the purpose and the environment of use in the same liquid crystal display element by structuring it so that the angle of visibility is controlled by means of an electrode formed between the third electrode and at least either the first or the second electrode. SOLUTION: With a voltage applied between the first and the second comb- type electrode 1a, 1b and to the third comb type electrode 2, an electrical field is generated as shown by an equipotential line 5. The oriented direction of a liquid crystal molecule 3 becomes parallel to the electrical field, with the liquid crystal molecule 3 responding in a direction oblique against the surface of an electrode substrate. When the liquid crystal molecule 3 so responds, its optical contribution differs greatly against a change in the angle of visibility; therefore, the angle is narrowed down. In addition, when the voltage applied to the third comb type electrode 2 is made lower than the one applied to the first 1a, the inclination in the oriented direction becomes lower for the liquid crystal molecule at the time of responding, thereby enabling the wider angle of visibility.

Abstract: PURPOSE:To effectively prevent the generation of scratches on the glass surface to be brought into contact with a belt by bringing the mesh belt treated with a phosphoric acid soln. into contact with the surface of a coating roller impregnated with a watersoluble graphite lubricant to stick the graphite only on the belt surface. CONSTITUTION:The mesh belt 1 is passed through an aq. phosphoric acid soln. to form a rust-preventive coating of iron phosphate on the surface of the belt 1. The belt 1 is then brought into contact with the surface of the coating roller 3 to stick the water-soluble graphite lubricant only on the surface of the belt 1, the surplus soln. is removed by rotary brushes 4 and 4, and the belt is dried by the heat in a furnace.

By this method, the graphite layer acts as a thermal buffer layer even at the time of conveying high-temp. glass placed on the belt 1, and the generation of cracks due to local quenching of the glass is prevented. In addition, since the graphite layer has excellent lubricity, the generation of scratches on the glass can be effectively prevented even in the case when the glass is rubbed by the belt 1.

Title: Semiconductor device
Inventor: SUGIYAMA MITSUHIRO
IPC: H01L21/28
Filed: 1990-07-17
Abstract: PURPOSE:To prevent an emitter resistance form being increased when an element is made fine by a method wherein impurities from a third insulating layer which has been formed on the sidewall part of a contact hole and which contains impurities at a high concentration are introduced into the side face part of polycrystalline silicon to be used as an emitter and the resistance at the side-face part of polycrystalline silicon to be used as the emitter is lowered. CONSTITUTION:A silicon oxide film 8 and ASG 9 are dry-etched anisotropically and are left only on the sidewall part of a contact hole. In succession, polycrystalline silicon is deposited; arsenic is introduced by an ion implantation method; the silicon is changed to N<+> polycrystalline silicon 10. Then, the N<+> polycrystalline silicon 10 is etched selectively; an emitter region 11 is formed by a heat treatment. At this time, the arsenic is diffused to the side-face part of the N<+> polycrystalline silicon 10 from the ASG 9; an arsenic concentration is increased also at the side-face part of the N<+> polycrystalline silicon 10 in which the amount of the arsenic introduced by the ion implantation method has been small. Thereby, when an electrode metal is sputtered onto the emitter after that, it is possible to prevent an emitter resistance from being increased largely even when an emitter current route is passed through the side-face part of the N<+> polycrystalline silicon 10.
