Title: Baking device for semiconductor substrate
Inventor: TASHIRO NAOTO
IPC: H01L21/027
Filed: 1987-02-18
Abstract: PURPOSE:To improve productivity and reliability by housing a semiconductor substrate coated with a photo-resist solvent into a vacuum chamber and heating and baking the substrate. CONSTITUTION:A vacuum chamber 1 heats a semiconductor substrate 2 housed in a heater 3. The vacuum chamber 1 stores the semiconductor substrate 2, an exhaust valve 6 is opened and the vacuum chamber 1 is evacuated by a vacuum pump 4, and exhausted continuously even during the heating of the semiconductor substrate 2. Since the baking treatment of the semiconductor substrate is executed in a vacuum, contamination generated due to the treatment of a gas atmosphere can be prevented, and degassing from the semiconductor substrate can be inhibited minimally when there is treatment in a high vacuum such as ion implantation as the next treatment process. Accordingly, the productivity of the treatment process is improved, and the counting error of the quantity of implantation can also be prevented.

Next, the flanges 4, 5 are welded by disc-shaped electrodes 7, 8. At this time cooling water 10 is supplied from a nozzle 9, and at the same time, pressure air is supplied into the space S through a hose 18. Then, the pressure air leaks through the clearance between the flanges 4 and 5 of the circumferential edge part where the seam-welding is not completed. Even if the cooling water 10 from the nozzle 9 reaches the clearance between the flanges 4 and 5, the cooling water 10 is scattered and will not enter the inside of the space S.

Title: Regenerating method of mixed bed desalting device
Inventor: TSURUMI TAKESHI
IPC: C02F1/42
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To effectively desorb and remove metal oxides depositing on an ion exchange resin by using a water which has been treated so as to reduce dissolved oxygen by a mixture gas of carbonic acid gas and nitrogen gas as the water to be supplied to the resin bed when the ion exchange resin is subjected to backwash, separation or transfer.

Title: Deformed v-shape overcurrent protecting circuit
Inventor: MATSUMOTO AIJI
IPC: H02M3/28
Filed: 1981-03-16
Abstract: PURPOSE:To obtain a protection circuit with less internal loss at an output short circuit, by giving a constant current characteristic while an output voltage of a DC stabiliezed power supply is comparatively high and a V-shape drooping characteristic, when the output voltage is lowered. CONSTITUTION:An overcurrent protection circuit of a DC stabilized power supply 1 consists of a current detection section 2 detecting  a signal proportional to an output current, a refernce votage generating section 4 of a series circuit of a R1 and, a Zener diode ZD3 having a low constant voltage characteristic than the specified output voltage E0 of the device 1, an amplifier 5 comparing and amplifying the output of the detection section 2 and the generating section 4, and a constant voltage controlling section receiving the output of the amplifier 5. When an overcurrent flows at the output of the device 1, although the output starts lowering, since a reference voltage is made with the ZD3, the constant current characteristics are shown until the output voltage is at a Zener voltage VZD or below. Further, when the load is increased, and the output voltage is lower than the voltage VZD, the voltage droops in a V-shape. Thus, the internal loss at the output shirt circuit can be decreased.
