IPC: B41M5/382
Filed: 1989-04-04
Abstract: PURPOSE:To enhance the grade of a recording image by enhancing heat resistance and preventing cutting or thermal deformation by using a thermal transfer material wherein a support is constituted of high density paper and a rear treatment layer is provided to the surface opposite to an ink layer of the support and moving the same in a state rubbed with a material to be recorded. CONSTITUTION:A thermal transfer material 1 and a material 2 to be recorded are continuously moved in the directions shown by arrows A, B by rotating a capstan roller 12, a pinch roller 13 and a platen roller 11 to perform recording on the material 2 to be recorded. At this time, a head 3 is not moved and the thermal transfer material 1 is moved so as to become slower than the material 2 to be recorded. In this double- density recording method, the support of the thermal transfer material receives the application of heat repeatedly within a short time and is required in high heat resistance and also required in high dimensional stability at the time of the application of heat and running stability on the size level of the heat generator of the thermal head. Therefore, an ink layer 100 is provided on the support 110 of the thermal transfer material 1 and a rear treatment layer 120 is further provided to the surface opposite to the ink layer 100 of the support 110. As the support 110, thin and high density paper is used to be capable of meeting the requirements of the support.

IPC: B23P21/00
Filed: 1993-04-13
Abstract: PURPOSE:To prevent an empty stage from being made by making a reversing device which reverses a vehicle body frame capable of moving synchronously with a conveyer for enabling flexible production on the same line. CONSTITUTION:When for instance, a vehicle body frame (f) where various automotive parts are mounted in reversed conditions are carried in a reversing device 20, the reversing device 20 is put in connection through a synchronizing attachment 26 for running synchronously with a conveyer to be run synchronously with the conveyer. By the operation of an operating part 42, a clamp part 41 rises along a frame body 40 of the vehicle body frame (f) received from the conveyer, and rotates by 180 degree. After setting the vehicle body frame (f) in a normal condition from a reversed condition, the vehicle body frame (f) is returned onto the same conveyer line L. It is thus possible to meet a change in the number of units to be produced flexibly, and prevent empty stages requiring no work from occurring in a line width.

IPC: B29C55/02
Filed: 1988-04-08
Abstract: PURPOSE:To make it possible to stably remove volatile scattering substances in a hot air, by so constituting that a part of circulating hot air is introduced from a circulating route through a heat exchanger and again circulated in said circulating route through said heat exchanger. CONSTITUTION:Volatile scattering substances such as oligomer etc. which are volatilized and scattered from a film 206 pass together with a hot air 203, through an entrance duct 106, and then through a radiation converting body 101, an electric heater 102 and a radiation converting body 101' via a heat exchanger 105. Thus, the volatile substances are completely burnt. The combustion gas as a result of this burning enters again the heat exchanger 105 to preheat the air 103 containing oligomers etc. before burning. Simultaneously, the combustion gas itself is cooled and discharged to the vicinity of a heater 208 within a hot air circulating device 200 through an exit duct 107. In this structure, the volatile scattering substances in the circulating hot air can be stably removed, and accordingly a high-quality film with less defects can be manufactured at low cost.

Filed: 1979-07-10
Abstract: PURPOSE:To permit the bent portion at the back of the contact point of the blade of the scissors to be readily formed in a simple operation by previously making the grinding surface itself formed on the peripheral surface of a grinding wheel bent inwardly. CONSTITUTION:The blade 1 is securely placed at a fixed position, and a grinding wheel 7 is arranged so that a grinding surface 7c inwardly bent contacts with the blade 1 from the upper portion to the lower portion of a handle 9 side periphery 3a  of a contact point 3 of the blade 1. Grinding is started from one end of the periphery 3a, with a rotating shaft 8 of the grinding wheel 7 inclined at a fixed angle to the longitudinal direction of the blade 1. With these conditions, the grinding wheel 7 is rotated to start grinding, and then it is gradually moved toward the other end of the periphery 3a in the direction of A. In doing this, the rotating shaft 8 is invariably located on a tangent of the circular contour of the periphery 3a. Thus, the bent portion at the back of the contact point 3 of the blade 1 is ground.
