Title: Thermal transfer apparatus
Inventor: NAGASHIMA MASAYOSHI
IPC: B41J2/48
Filed: 1984-08-23
Abstract: PURPOSE:To print corresponding to a character pattern by projecting the controlled light on the surface of the melted ink of a thermal transfer medium directly with the high energy light from a light source is switching controlled by a character pattern signal. CONSTITUTION:An electric current is flowed corresponding to the reflected amount of light by a phototransistor being projected a reflected light from a manuscript 1, and a voltage is impressed to a branch line 5B at a photoswitching means 5. A flash is generated from a light source 4 synchronizing with this, and projected into a light conducting line 5A. Then, this flash is refracted at the branch line 5B corresponding to an impressed voltage to the branch line 5B, and the light output corresponding to a letter pattern of the manuscript 1 is projected toward a transfer medium 6. The light output of the photoswitching means 5 is projected to a heat melting ink surface 6B directly transmitted through the base film 6A, since the base film disposed at the front step side of an incidence course of this light is optically transparent, and a molten ink is transfered to the medium to be transfered by the separation of the tranfer medium 6 and the medium 7 to be transferred.

Title: Sealing method of pressurized tank using roll
Inventor: UEHA AKIRA
IPC: B29C65/48
Filed: 1982-10-06
Abstract: PURPOSE:To prevent the leakage of compressed air from a pressurized tank to and from which an item to be processed is sent and taken out by a pair of roll additionally installed to the tank by pressing a packing composed by pasting high molecular material and rubber together with a metal plate inserted as a core material against the circumference of rolls and sealing material provided at the side wall of the tank. CONSTITUTION:A patch plate 4 which is prepared by such a method that a core material (b) is inserted into a seal plate (a) and a rubber plate (c) is integrally pasted to the back of the seal plate is inserted into a groove 2 of a pressurized tank 1 and it is caused to tightly contact with a roll 3. At this time, it is arranged so that the rubber plate (c) is formed into V shape and a round rubber bar is placed in the V groove, or it is formed into triangle to have elasticity. In this case, the core material (b) prevents the expansion and contraction of the patch plate 4 in its longitudinal direction and also prevents a gap from being generated at the edge of the patch plate and makes the sealing of back surface of roll 3, 3' complete. Thus, the contact pressure between the roll and the patch plate can be easily adjusted to conform to the shape of the roll by utilizing the elasticity of rubber, and also such composition displays the same effect for preventing the wear of both parts.
