Title: Liquid crystal shutter device
Inventor: YUASA KAZUHIRO
IPC: G02F1/133
Filed: 1986-12-25
Abstract: PURPOSE:To reduce the cost of production and to provide memory performance by attaining the molecular orientation of a ferroelectric liq. crystal with insulating films and by applying a pulse signal whose fall end has a gradient so as to turn on or off liq. crystal shutters. CONSTITUTION:Micro-shutters are zigzag arranged in two rows at prescribed intervals. Insulating layers 26, 27 act as orienting films for initially orienting the liq. crystal molecules of a ferroelectric liq. crystal 28 like a TN (twisted nematic) liq. crystal. The layers 26, 27 may be made of polyimide. The initial orientation can be attained by rubbing the surfaces of the orienting films. When an electric field which is reversed at the fall end of a driving pulse signal is applied to the liq. crystal layer, the molecular orientation of the liq. crystal 28 is reversed, so the optically turned-on liq. crystal shutters are optically turned off. Thus, memory performance can be provided to a liq. crystal sheet 14 suitable for mass production with the ferroelectric liq. crystal 28 initially oriented by the orienting films like a TN liq. crystal.

Title: Capacitor discharge ignition system for cylinder injection two-cycle engine
Inventor: YAMADA AKIRA
IPC: F02P3/00
Filed: 1990-11-13
Abstract: PURPOSE:To ensure ignition and reduce the power consumption of a battery by varying the discharge energy of capacitors corresponding to detected driving areas. CONSTITUTION:The discharge energy of capacitors 28a-28d is varied corresponding to a driving area which is detected by a driving area detecting means 20. As a result, when the discharge energy of the capacitors 28a-28d in a layered- combustion driving area is increased more than in a uniform-combustion driving area, spark ignition as strong as increased spark energy is secured even if during low-rotating-speed driving flammable mixture is somewhat apart from a spark plug 10 or the atomization of fuel is insufficient. Also, in a uniformly mixed combustion area discharge energy can be reduced. It is thus possible to improve ignitability in all driving areas and reduce the power consumption of a battery.

Abstract: PURPOSE:To reduce a bump electrode size and an array pitch without any restriction due to test by providing a temporarily-connected pad instead of a bump electrode for test in a size and array pitch suited for test by utilizing the inside of an integrated circuit device and the area on the scribe region between the two. CONSTITUTION:After adhering a conductive ground film 11 of bump electrode to the entire surface of a wafer, a bump electrode 13 is allowed to grow selectively at a specified position by plating with this ground film 11 as an electrode and then the ground film 11 is photo-etched to form the tentative connection pad connected to the bump electrode 13. After testing an integrated circuit device through this tentative connection pad 15, the tentative connection pad 15 is eliminated for creating the tentative connection pad 15 in size and array pitch suited for test utilizing an open space on the wafer and for performing test through this tentative connection pad regardless of the bump electrode 13. Thus, the size and array pitch of the bump electrode can be reduced to several fractions of that heretofore.

IPC: B32B15/08
Filed: 1990-11-16
Abstract: PURPOSE:To obtain a metallic structure, on a surface of which a porous layer having performance such as air permeability, liquid-absorbing properties, liquid-containing properties, etc., is fast stuck and also has the rust-proofness of a metal, by forming a synthetic resin-sintered layer on the surface of a metallic body through a polyolefin layer.

Polyolefin must have a melt index (MI) of six or more in order to improve the adhesive properties of a metal and a synthetic resin-sintered layer, 10-200 preferably, and a substance containing a polar group such as a carboxylic acid group is recommended. A pinhole is easy to be generated and performance preventing corrosion is lowered in the thickness of 0.1mm or less of a polyolefin layer. Polystyrene and other kinds are cited as a synthetic resin, but high density, low density and straight-chain low-density polystyrene and polypropylene having MI of 1-0.001 are recommended particularly as polyolefin. The power of said polyolefin having MI of six or more is used on the surface of a metallic body and a film is formed, and the upper section of the film is coated with the powder of said synthetic resin under the state in which the film is melted, thus forming a sintered layer.
