Title: Opening and closing device
Inventor: KATSUURA NOBUO
IPC: E05C21/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent complication of a device by providing an opening and closing mechanism elastically deformed with designated force to be disengaged and be put in the open state, and an inhibit mechanism for inhibiting the elastic deformation when vibration not less than a designated value is applied. SOLUTION: When a door 3 is pulled in the direction of an arrow x, designated force is applied to an engagement part 17 of an opening and closing mechanism 11 and an engagement part 18 of an opening and closing mechanism 12, both are elastically deformed to expand a gap 19, and the engagement part 18 is slipped off from the gap 19 to open the door 3. When an earthquake occurs so that vibration not less than a designated value is applied, a sphere 44 is moved in the direction of an arrow X, and a release piece 42 is turned on a rotating shaft 47 counter-clockwise to release the engagement of a claw part 45 with an engagement groove 46.  Subsequently, a lock piece 23 is moved in the direction of the arrow X by the energizing force of a coil spring 43, thereby inhibiting the elastic deformation of the engagement part 17 and locking the engagement state of the engagement parts 17, 18 to prevent the door 3 from being opened. Thus, when vibration not less than a designated value is applied, the opening and closing mechanism is directly locked so as to prevent complication of a device.

Title: Drive controller for pulse motor
Inventor: INOUE TAKASHI
IPC: H02P8/12
Filed: 1981-09-19
Abstract: PURPOSE:To eliminate the irregular torque of a pulse motor by limiting a current which flows through a coil for the prescribed period of time at the switching time of exciting phase, thereby equalizing the current which flows through the coils. CONSTITUTION:A current limiter 5 is added to a distributor 3 which inputs an incremental pulse PF and a direction switching signal RF and outputs selection pulses P1-P4 and control pulse PT. This limiter 5 outputs a prescribed period stop pulse PS to a constant-current circuit 2 when inputting a control pulse PT, thereby interrupting the output of the pulse voltage from the circuit 2 for the prescribed period, and interrupting the current flowing through the coil of the pulse motor 1. In this manner, even if the current which flows through the coils of a pulse motor is controlled constantly by the constant-current circuit, the current flowing through the competitive coil in the excitation of the pulse motor becomes uniform, thereby eliminating the irregular torque and erroneous stepping angle.

Title: Apparatus for treatment with chemical agent
Inventor: MACHIDA AKIRA
IPC: C02F1/00
Filed: 1981-09-24
Abstract: PURPOSE:To enable to maintain an amount of a chemical agent in a treating cell constant, by constituting piping between a cell for treating wafers with the chemical agent and a tank for supplying the chemical agent in a semiconductor- manufacturing process with two systems of a large flow rate one and a small flow rate one, and carrying out large amount supply at the initial stage and small amount supply in response to consumption. CONSTITUTION:An amount of trichloroethylene 1a necessary for a treating cell 5 is ordinarily reserved in a tank 1 for supplying the chemical agent. When the treating cell 5 is empty, an air valve 3 at the side of a large flow rate system is opened to supply all of trichloroethylene 1a in the tank 1 through pipings 2a and 4 to the treating cell 5 and then closed. Thereafter, trichloroethylene is received in the tank 1 from a main tank 8 through a supply pipe 9. When a semiconductor wafer is processed in the following step, the surface of the liquid in the cell 5 is lowered by the consumption of trichloroethylene such as its natural evaporation and adhesion to the surface of the wafer. Hence, an air valve 6 in a small flow rate system is periodically opened, e.g. for a fixed time by every treating time for the set of the semiconductor wafers 1, to make up for the amount of trichloroethylene 5a in the cell 5 through piping 2b.

Title: Liquid injection type screw fluid machine
Inventor: FUJIWARA MITSURU
IPC: F04C25/02
Filed: 1990-06-11
Abstract: PURPOSE:To decrease resistance of oil against rotation of each rotor by enlarging the bore radius of a bore inner wall surface near bore intersection lines on compression side more than that of the other portion of the bore inner wall surface, which faces a channel located in a stroke which does not communicate with either low or high pressure opening. CONSTITUTION:The space between the edge of each rotor 2, 11 and each bore inner wall 7, 9 is enlarged by enlargement of a bore radius near both of bore intersection lines 10 on compression side and a clot of oil gathered to each rotor 2, 11 is removed to the back of the edge 3, 12 of each rotor by the difference in pressure between an actuating space and an actuating space behind the edge 3, 12 of each rotor. Resistance against the motion of each rotor is thus decreased and so is the rotary power of each rotor. Since a portion where the bore radius is enlarged is restricted to near both of the bore intersection lines 10 on the compression side, oil films would not be removed from the space between a bore inner wall surface and each edge. The danger of gas leakage is thus eliminated regardless of enlargement of the space between the edge of each rotor and the bore inner wall.
