Title: Liquid crystal display device
Inventor: TSUDA KEISUKE
IPC: G02F1/1337
Filed: 1988-08-17
Abstract: PURPOSE:To obtain an excellent image display without making a TFT element defective by orienting liquid crystal horizontally on one substrate and vertically on the other substrate. CONSTITUTION:The substrate 1 with the TFT element after the vertical orientation and the other substrate 1 after the horizontal orientation are stuck together having their electrode sides opposite each other, and the liquid crystal is injected and oriented so that liquid crystal molecules 10 slant gradually form vertically to horizontally from one substrate 1 to the other substrate 1. Then when the axis of polarization of a linear polarizer is arranged outside the substrate which is oriented horizontally, transmissivity-voltage characteristics have a slow gradient and a multigradational display is easily made. Consequently, such a defect as the electrostatic breakdown of the TFT element due to rubbing is not caused and an excellent image having no display defect is obtained.

Title: Glass fiber composition having low dielectric constant
Inventor: YOKOI KOJI
IPC: C03C13/00
Filed: 1987-08-18
Abstract: PURPOSE:To provide the title compsn. having relatively low melting temp. and spinning temp. and high productivity having also satisfactory water resistance by specifying the compsn. of the glass fiber. CONSTITUTION:The glass fiber compsn. having low dielectric constant has a compsn. consisting of 50-70mol.% SiO2, 20-40mol.% B2O3, 3-10mol.% Al2O3, 0.5-8mol.% CaO, 0-10mol.% MgO, 0-6mol.% SrO, and 0-10mol.% ZnO. In this compsn., SiO2 is <50%, the chemical durability of the glass fiber is deteriorated. When it is >70%, melting and spinning of the glass fiber are difficult due to the increase of viscosity of the compsn. B2O3 has high depressing effect for dielectric constant, so it is effective as a flux component. When it is <20%, the dielectric constant is too high and the viscosity becomes high. When it is >40%, the chemical durability is severely deteriorated. When the content of Al2O3 is <3%, the chemical durability is deteriorated. When it is >10%, the dielectric constant is too high and deterioration tendency is also deteriorated. CaO is particularly effective for the improvement of water resistance. When it is <0.5%, the effect is eliminated; when it is >8%, the dielectric constant is too high.

Title: Viscous heater
Inventor: KADOKAWA MASARU
IPC: F24J3/00
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a viscous heater capable of controlling calorific value with ease while improving carrying properties on a vehicle. SOLUTION: A second movable member 115 forming the inner wall of a heat generation chamber 102 located at a position outside a heater shaft 104 in its radial direction is made to displace in the radial direction of the heater shaft 104, and air is also made to enter the heat generation chamber 102 together with viscous liquid.

Title: Amplitude correction circuit
Inventor: WATANABE TETSUJI
IPC: H04N5/68
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To enhance the continuity of displayed video image by correcting amplitude of a deflection current so as to suppress an amplitude change caused accompanying circuit temperature drift or the like. SOLUTION: Current transformers 11a, 11b as a detection means 11 detect an amplitude change of a deflection current given to a deflection yoke 2 a current-voltage conversion circuit 12 integrates the detected current to obtain a sawtooth deflection voltage waveform equivalent to that of a deflection current. A comparator circuit 13 compares the sawtooth deflection voltage waveform from the current-voltage conversion circuit 12 with a prescribed voltage waveform that is an optional reference value to generate a correction signal in response to the amplitude change in the deflection current and to give it to horizontal and vertical deflection circuits 6, 7. The horizontal and vertical deflection circuits 6, 7 correct the amplitude of the deflection current based on the correction signal supplied by using, e.g. an amplitude control element.  Thus, even when an amplitude change in the deflection current takes place due to temperature drift the amplitude change is suppressed to cause stabilization and the continuity of a displayed video image on a large sized screen consisting of pluralities of CRTs is ensured.
