Title: Tape feeder
Inventor: HASEGAWA HIROYUKI
IPC: B65H59/04
Filed: 1992-04-23
Abstract: PURPOSE:To provide a tape feeder capable of stabilizing tension applied to a tape by providing interlocking mechanism for reducing the pressing force of the brake shoe of a brake part according to the angle-of-rotation of the shaft of a winding diameter detecting arm changed with the decrease of the winding diameter of a tape pad. CONSTITUTION:When a winding diameter detecting arm 11 is rotated around its shaft 12 according to its tracing action, the gears 21A, 21B of interlocking mechanism 20 transmit this angle of rotation at the fixed ratio to a pressing lever 25. The pressing lever 25 compresses a coil spring 34 according to the angle of rotation so as to increase/decrease braking force for pressing a brake shoe 7 to a brake drum 6. In the case of the winding diameter of a tape pad 3 being large, the coil spring is compressed hard to increase braking force. When the winding diameter of the tape pad is decreased, the coil spring is elongated to lower braking force. This relationship is correctly proportional, and the tension of the tape becomes always constant regardless of the winding diameter.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor device which enables in-process screening of a gate oxide film, by performing heat treatment in a high-temperature nonoxidative atmosphere after formation of the gate oxide film. SOLUTION: Pyrogenic oxidation is performed for five minutes at 850 deg.C by using a resistance heating type heat treatment furnace, thereby forming a gate oxide film 2 of approximately 8nm on a silicon substrate 1. Then, an argon(Ar) atmosphere is substituted in the same furnace and the temperature is raised to 1000 deg.C, thus performing heat treatment for five minutes in the Ar atmosphere. As a result, a weak spot 2a existing in the gate oxide film 2 is vaporized to be converte into a pin hole PH. A gate electrode 3-1 formed on the pin hole PH forms a short circuit state with the silicon substrate 1. Thus, the weak spot in the gate oxide film is converted into the pin hole to cause an initial short circuit failure, and this failure is detected and removed in a pellet check after the process. Therefore, in-process screening of the gate oxide film is enabled.

Title: Accelerating and decelerating rotating actuator
Inventor: ISHIKAWA KAZUTOMI
IPC: F15B15/12
Filed: 1989-05-24
Abstract: PURPOSE:To smooth acceleration and deceleration at the start and termination of rotation in a short time and to increase the rotating speed by providing a difference in level between a fixed block and the rotating end surface of a rotor to divide a chamber and providing a taper escape way on a difference in level surface portion where the fixed block and the rotor are matched. CONSTITUTION:Oil entering through a port E is changed into force in a chamber F to push a rotor 6 in the opposite direction and divided into chambers G, H. The oil escapes from the chamber G to a port D, and only a taper escape way J portion is used as an escape way for the back pressure in the chamber H. If the J portion is formed as a plane taper, a U-shaped taper or the like, the section is narrowed to gradually decrease the speed and at last stop rotation at the end surface. On the contrary, in case of rotation by force from the port D and the chamber G, the sectional area is gradually widened to increase the speed, and the forces of the chamber G and H are added to rotate at high speed. Accordingly, if a symmetrical difference in level is provided between the ports D, E, pressure applied from either of ports D, E enables uniform accelerating and decelerating operation.
