IPC: H01L21/3065
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor processor which can inhibit adhesion of a reactant to a cooling water piping, by which cleaning work is easy and whose manufacture yield improves. SOLUTION: The upper part (namely, an area facing the inner part of a processing room) of the cooling water piping 14 fixed on the back-side of an upper electrode is covered by a reactant adhesion preventing film 15. The reactant is prevented from being directly adhered to the cooling water piping 14 with the existence of the reactant adhesion preventing film 15. Furthermore, the temperature of the back-side of the cooling water piping 13 comparatively rises and the cooling effect deteriorates with the existence of the reactant adhesion preventing film 15. Thus, the adhesion of the reactant having a characteristic that it easily adheres to a place with a low temperature to the reactant adhesion preventing film 15 is suppressed.  The temperature of the front-side (namely, a face which is brought into contact with the upper electrode 11) of the cooling water piping 14 drops and cooling effect on the upper electrode 11 increases.

Title: Heating device
Inventor: SATO NOBUO
IPC: B29L22/00
Filed: 1985-01-16
Abstract: PURPOSE:To enable to satisfactorily heat a preform from both the inside and outside thereof by a method wherein a heat pipe is used as the heating source from the inside of the preform. CONSTITUTION:When heat is generated at the heater 6 of a heating oven 4 and at the same time the input zone 3 of a heat pipe 1 is heated by a heating source 7 under the state that a preform P is fitted in the heating oven, the preform P is heated from the outside by the heater 6 and from the inside by the working zone 2 of the heat pipe 1. Accordingly, the whole preform P is heated very quickly and at the same time the uniformly heated state of the preform P can be realized. In addition, because the quantity of heat given off at the working zone 2 truely follows the heating rate at the input zone 3 by the heating source 7, the heating of the inside of the preform P by the working zone 2 can be controlled by properly controlling the heat quantity, which the heating source 7 delivers, in the same manner as the heating of the preform by the heating oven 4.

Title: Protection circuit of multi-output power
Inventor: OKADA YUKIO
IPC: G05F1/577
Filed: 1985-01-16
Abstract: PURPOSE:To simplify the circuit and to attain remarkable cost-down by using a clover circuit so as to short-circuit an output terminal with a high voltage even when an overvoltage is generated at the output terminal with a low voltage, biasing forward a diode and short-circuiting the output terminal with a low voltage. CONSTITUTION:If an overvoltage is generated at an output terminal for +12V, a Zener diode 6 is conducted to trigger a thyristor 5, which is conducted. As a result, the terminal 2 is short-circuited, causing a load to be protected from the overload. If and overvoltage is generated at an output terminal 3 for +5V next, a Zener diode 7 is conducted to conduct the thyristor 5. As a result, the terminal 2 is short-circuited and grounded and a diode 9 is biased forward, then the terminal 3 is connected to the terminal 2 via the diode 9 and short- circuited, causing the load to be protected similarly. Since the diode 9 is biased reversely at normal state, the terminals 2 and 3 are isolated with each other.

Title: Emergency shutoff valve
Inventor: BABA AKIHISA
IPC: F16K31/14
Filed: 1987-01-16
Abstract: PURPOSE:To enhance the reliability as an emergency shutoff valve, by moving a connecting cylinder by means of compressed gas prior to the operation of a high pressure closing valve device, thereby disconnecting the connection between a gear and a valve stem, both of which can usually be rotated by a hand-operating handle. CONSTITUTION:Since a valve stem 2 and a worm wheel 7 is connected at an ordinary time via a connecting cylinder 10, the valve stem 2 can be rotated with light force through handle operation via both a worm 8 and a worm wheel 7. At the time of emergency, however, compressed gas makes a piston 16 go up, so that both gear trains 12 and 13 are separated from each other, thereby disconnecting the connection between the worm wheel 7 and the valve stem 2. At this time, since the piston 16 is up, a cylinder 14 and an discharge hole 22 are connected via a ring connecting-hole 18. Thus, the compressed gas enters into an automatic valve deice 3, thereby quickly closing the valve.
