IPC: B29K101/10
Filed: 1985-02-13
Abstract: PURPOSE:To enable to adjust the press pressure with very good precision by a method wherein the titled device is made into such a structure that the driving force of the motor is converted into a thrust force through the ball screw, the nut and so forth, the thrust force is given to the moving platen through the double torque mechanism, and the top force and the bottom force are clamped. CONSTITUTION:The turning force of a motor 16 is transmitted to a ball screw 20 through a power transmission system 17 and a bevel gear pair 18 and 19. When the ball screw 20 is made to revolve, a nut 21 to screw in the ball screw 20, that is, a nut housing 31 is made to ascend. The turning force of the motor 16 is converted into a thrust force in such a way and the thrust force is transmitted to a moving platen 13 through a double torque mechanism 30. The moving platen 13 is made to ascend by such the thrust force and the angle theta of the torque mechanism 30 goes becoming smaller gradually. Finally, a very large force is generated to the upper direction in the diagram near a value that the angle theta becomes 0 from the nature of the torque mechanism 30, and a bottom force 15 and a top force 14 are clamped with a prescribed pressure by this force.

IPC: H01L21/22
Filed: 1992-02-14
Abstract: PURPOSE:To inhibit the formation of a compound of platinum and silicon and minimize the variability of forward voltage drop by speeding up the cooling operation after platinum diffusion when heating a semiconductor substrate to a high temperature and diffusing platinum in the substrate. CONSTITUTION:An n-type Si wafer is adopted as a semiconductor substrate. After the formation of a p-n junction, the surface of the substrate is coated with a platinum source. A boat 4 where an Si wafer 3 is loaded is inserted into the center of a furnace by means of a boat loader 5 from one end of a furnace tube 2 of an electric furnace 1 while nitrogen gas 8 is passed into the furnace tube 2 from a gas intake pipe 6 on the other end of the furnace tube 2 where heat treatment is carried out. After the end of Pt diffusion, the boat 4 is pulled out up to a portion of the furnace tube 2 outside the furnace in a short time, say, 1 to 10 seconds, by means of the boat loader 5. Vent holes 7 are bored in this portion of the furnace tube 2. When the N2 gas 8 is sprayed on this portion from the outside, the temperature of the wafer 3 drops immediately. The Si wafers thus obtained are laminated while the forward voltage drop of manufactured diodes is 29V on the average and their variability amplitude is 4V.

Title: Apparatus for testing and evaluating ic
Inventor: HASEGAWA TOMOHARU
IPC: G01R31/02
Filed: 1985-02-15
Abstract: PURPOSE:To simplify the mounting of IC and to enable long-term succeeding use, by utilizing the change in the lengths of a shape memory alloy spring in an usual temp. state and a test temp. state. CONSTITUTION:Because a shape memory alloy spring 8 is held to a shrunk state at predetermined temp. or less, an IC pin 4 can be arranged in a recessed part 6a in a state contacted with a metal plate 7. Next, in a test temp. state the spring 8 extends to an A-direction and a press plate 9 presses the pin 4 from the inside to contact the same with the metal plate 7 under pressure. By this method, certain electrical connection is held between the pin 4 and the metal plate 7 in the test state. When temp. is lowered to predetermined one after the test was finished, the spring 8 is shrunk to release the pressing state of the pin 4 and, therefore, IC can be simply taken out. Therefore, only by placing or taking out an IC main body 3, pressure contact and the release thereof are automatically performed by the action of the spring 8 and, therefore, connection is certainly secured by simple operation without abrading and deteriorating the connector part.
