Title: Liquid crystal display device
Inventor: AZUMA HIDEAKI
IPC: G02B6/00
Filed: 1994-08-10
Abstract: PURPOSE:To prevent the unequal display occurring in nonuniform transfer of heat to a liquid crystal display panel by making the area of a heat transfer sheet larger from near the reflection plate of a light source toward the display surface direction of the liquid crystal display panel. CONSTITUTION:A planar light transmission plate 4 is arranged parallel with the axial direction of the slender light source 3 in such a manner its side face faces to the light source 3 in proximity. The light reflection plate 1 is arranged on the one surface of the light transmission plate 4 and a light diffusion plate 5 is arranged on the other surface. The reflection plate 2a of the light source is extended in the display surface direction of the liquid crystal display panel from near the light source and is integrated and arranged as the heat transfer sheet 7. The reflection plate is so constituted that its area is larger the furtherer from the light source 3. Then, the heat transfer sheet 7 acts as a heat radiating plate or heater plate on a light reflection plate side 1. Namely, its heater effect acts in the position furtherer from the light source 3 to make the temp. uniform within the effective region of the liquid crystal display panel and simultaneously, the heat transfer sheet acts to decrease the absolute value of the heat transmission quantity to the liquid crystal display panel by the heat radiation effect.

Title: High-molecular material for thermistor
Inventor: OMOTO MASANOBU
IPC: C08K5/17
Filed: 1990-07-16
Abstract: PURPOSE:To obtain a thermistor, which is small in moisture absorption property and is superior in heat resistance, electrical characteristics and the like, by a method wherein the high- molecular material for the thermistor is made into one consisting of a graft copolymer, which is obtainable by graft-polymerizing vinyl acetate on an ethylene-vinyl acetate copolymer, and a specified amount of a cation antistatic agent and the like. CONSTITUTION:The high-molecular material for a thermistor is made into one consisting of 100 parts weight of a graft copolymer, which is obtainable by graft-polymerizing 90 to 60wt.% of vinyl chloride on 10 to 40wt.% of an ethylene-vinyl acetate copolymer, in which the content of vinyl acetate is 40 to 80wt.%, and 1 to 5 parts weight of a cation antistatic agent. When the content of the vinyl acetate in the ethylene-vinyl acetate copolymer is decreased, the electric characteristics (the constant B of the thermistor) of the thermistor are reduced and in contrast with this, when the content of the vinyl acetate is increased, the mechanical physical properties of the thermistor at a high temperature are reduced. Accordingly, the content of the vinyl acetate is set at 40 to 80wt.%. When the content of the ethylene- vinyl acetate copolymer in the graft copolymer exceeds less than 10wt.%, and 40wt.%, the electrical characteristics are reduced. Moreover, when the addition amount of the antistatic agent is decreased, the electrical characteristics are reduced and when the addition amount is increased, the heat resistance of the thermistor is reduced. Accordingly, the addition amount of the antistatic agent is set at 1 to 5 parts weight.

IPC: B29C65/20
Filed: 1981-11-24
Abstract: The welding apparatus serves for the purpose of butt-welding of plastic pipes of diameters larger than 500 mm. All the work is performed by means of the welding apparatus from inside the pipe. Thereby the working time is reduced, the welding quality ensured, and the installation becomes faster. Lifting cranes and heating tents become unnecessary. A novelty is also the possibility of welding pipes together at an angle position. As the welding apparatus is collapsible, it may also be advantageously used for repair work on old pipes in the ground (relining), with a minimum exposure of the pipes.
