Title: Transferring apparatus for clean room
Inventor: TAMURA AKIRA
IPC: F16H49/00
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce generation of particles by comprising a rotating shaft cover which is located between a male magnetic screw and a female magnetic screw and is formed of a non-magnetic material for hermetically closing the rotating shaft and a driver cover for hermetically closing the driver. SOLUTION: A transferring apparatus comprises a rotating shaft 12 provided with a male magnetic screw 13 at the external circumference, a stepping motor 27 for rotating the rotating shaft 12 and a slider 18 provided with a female magnetic screw provided against the male magnetic screw 13. Thereby, when the rotating shaft 12 is rotated, the female magnetic screw slides on the slider 18 by receiving a magnetic force of the male magnetic screw 13. Moreover, a seal pipe 17 formed of non-magnetic material hermetically closing the rotating shaft 12 and a driver cover 28 for hermetically closing the driver are comprised to keep the apparatus under more negative pressure condition than the clean room via an air joint 29 by means of a vacuum pump. Therefore, air does not flow into the clean room from the hermetically closed space and thereby any particle does not enter the clean room.

Title: Gas regeneration and circulation apparatus in gas laser apparatus
Inventor: NAKAYAMA KAZUO
IPC: H01S3/036
Filed: 1987-10-26
Abstract: PURPOSE:To prevent an oil mist from entering a circulation system by providing the following: a diaphragm-type vacuum pump which does not use oil in the circulation system; a water-removing part used to remove water; a catalyst part used to regenerate a gas. CONSTITUTION:When a laser gas regeneration apparatus 6 is operated in order to reduce a consumption amount of a laser gas, a valve 17 is shut; a supply operation from a laser gas bomb 15 is stopped; valves 4, 12 in a circulation system are opened. Because a pump 5 used to regenerate the laser gas is a diaphragm-type vacuum pump which does hot use oil, an oil mist does not enter the circulation system. Water is removed at a water-removing part 8 inside the circulation system, a reaction of CO+1/aO2 CO2 is promoted at a catalyst part 9. Because a catalytic reaction is promoted at this catalyst part 9, the gas is heated to 200-250 deg.C by using a heater 13; the gas is later cooled down to about room temperature by using a cooling coil 10 and is returned to a laser oscillator 1. By this setup, a laser can be oscillated stably.

Title: Deflection circuit
Inventor: KURODA ATSUSHI
IPC: H04N3/27
Filed: 1985-11-30
Abstract: PURPOSE:To keep constantly the duty of the output horizontal oscillating pulse of a horizontal oscillation circuit substantially constant and to prevent the deficiency in driving a horizontal output circuit and a turbulence of the deflection by changing the pulse duration of a horizontal oscillation pulse according to the frequency of a horizontal synchronizing signal. CONSTITUTION:If the frequency of the input horizontal synchronizing signal is moved to a low frequency side within a previously expected frequency range, the output of a frequency/voltage conversion circuit 3 is reduced, and the negative electrode output of a control circuit 13 increases an absolute value and is reduced. Therefore, the collector current of a transistor (TR)Q2 for varying a charging current in a monostable multibrator 12 is reduced and a charging time in a capacitor C is increased. As a result, tough the duty of the output of the horizontal oscillation circuit 2 is lower than 50%, the output of the vibrator 12, namely the duty of the horizontal oscillating pulse is maintained substantially at 50%. Accordingly, the on time of the horizontal output TR in the horizontal output circuit 5 is substantially equal to an off time, even when the input horizontal synchronizing signal is moved to the low frequency and the deficiency in driving or the stop of driving of the circuit 5 can be avoided.
