Title: Liquid crystal display device
Inventor: SHIMADA SHINJI
IPC: G02F1/1343
Filed: 1990-11-21
Abstract: PURPOSE:To prevent generation of a disclination line on the center part of a picture element electrode by forming a projecting step difference territory having height over 1000 A and the like along the end edge of the picture element electrode positioned on the opposite side to the opening direction of a pretilt angle of liquid crystal molecules on the picture element electrode. CONSTITUTION:Along the end edge of a picture element electrode 4 positioned on the opposite side to the opening direction of a pretilt angle of liquid crystal molecules on the picture element electrode 4, a projecting step difference territory 5 having height over 1000A or a recessed step difference territory having depth over 1000A is formed on the picture element electrode 4. Consequently, though a territory of reverse rising orientation of liquid crystal molecules is generated due to the drive signal of a signal line or a scanning line positioned in proximity to the end edge side of the picture element electrode 4, spreading of the territory to the center part of picture element electrode is obstructed. Hereby, a disclination line to deteriorate display quality can be prevented to generate on the center part of the picture element electrode 4.

Silane coupling agent is dissolved into water solution or organic solvent and the concentration is 0.1g/l or more by dipping or spraying. A heat-curing resin which is used for general copper-clad laminated plate is applied to or impregnated into a paper substrate or glass fiber cloth material as an insulation organic material which is lamination-unified with copper foil. An electroless copper plating or an electroless nickel plating is used as an electroless plating. An anchoring effect improves adhesion force between an electroless copper plating and insulation organic substrate.

Filed: 1991-12-03
Abstract: PURPOSE:To prevent respectively over-shoot and under-shoot of an air fuel ratio while improving convergence property of an air fuel ratio to a window by setting the renewal width of a leaning value to a variable value according to post O2 sensor output. CONSTITUTION:An air fuel ratio feed back correction amount alpha is found out by a calculating means 40, from a value of a basic control constant corrected by a learning value PHOS read from a memory 37, and basic injection amount Tp is corrected by the air fuel ratio feed back corrected amount alpha. The renewal width DPHOS of the learning value is set by a setting means 45 in such a way that it is increased when it is away from the intermediate value of a post O2 sensor output serving as a center, and it is decreased when it is near the intermediate value. It is thus possible to renew the learning value while using the renewal width DPHOS.

Abstract: PROBLEM TO BE SOLVED: To expand a dynamic range by switching over a high-frequency light flux to be a measuring light when a mobile body approaches an interferometer, and a low-frequency light flux to be a measuring light when it recedes from the interferometer. SOLUTION: A twisted nematic liquid crystal 20 is oriented in such a manner that it is not optically rotated when the electric field is turned on and is optically rotated by 90 degrees when the electric field is turned off. The voltage applied to an electrode 21 is controlled by a CPU. When the electric field is turned on, circular polarized lights on the right and left sides are converted by a λ/4 plate into linear polarized lights crossing orthogonally with each other, and a high-frequency light flux f2 is converted into a p polarized light. The p polarized light is transmitted through a polarization beam splitter 4, and the light flux f2 is used as a measuring light b2 .  When the electric field is turned off, the polarization direction of both linear polarized lights on the rear side of the plate 3 is turned 90 degrees, and a low-frequency light flux f1 is converted into a p polarized light, then it is used as a measuring light b2 . When a mobile body approaches to an interferometer, the light flux f2 as the light b2 is further mudulated to a high-frequency side, and on the other hand, the mobile body is apart therefrom, the light flux f1 as the light b2 is further modulated to a low-frequency side, resulting in expansion of dynamic range.
