Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of generated sludge easily while saving a space by a method in which in an apparatus in which separated sludge is introduced into a sludge treatment tank and the volume of the sludge is reduced by microorganism-treatment, part or the whole of the treatment tank is brought intermittently into conditions in which microorganisms to be contained in the introduced sludge are solubilized. SOLUTION: In a drainage treatment facility equipped with an activated sludge tank 1, a precipitation tank 2, and a sludge treatment tank 4, part or the whole of the tank 4 like a pH treating agent charging device 14 intermittently, a means for solubilizing microorganisms to be added into introduced sludge is installed. A heating means, a ultrasonic wave generator, a UV radiation device, a germicide charging device, and others can be used as the solubilization means. In the solubilization, the tank is made aerobic, temperature is controlled at about 45 deg.C.

Title: Turbo molecular pump
Inventor: KUBO MASAHIDE
IPC: F04D19/04
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a turbo molecular pump which can be heated at its suction port part and thereby provide a degree of vacuum as high as about 10<-8> Pa. SOLUTION: A turbo molecular pump has a heating means 15 for selectively heating its suction port 3. The suction port 3 of the turbo molecular pump is heated by the heating means 15 for the degassing of the suction port 3, and a high degree of vacuum is obtained by preventing gas components from being discharged from the suction port 3 under a high vacuum. To obtain a high degree of vacuum, the suction port 3 of the turbo molecular pump is preheated by the heating means 15, and gas components are expelled from the suction port 3 for degassing. Thus even if the degree of vacuum is enhanced, no gas components are discharged from the suction port 3, and the high degree of vacuum can be achieved.

Title: Power unit and discharge-lamp operating device
Inventor: SUGIYAMA MASAHIRO
IPC: H02M7/537
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a discharge-lamp operating device that can surely reduce higher harmonics. SOLUTION: When the voltage of a transistor Q1 becomes lower due to load fluctuation, etc., the voltage of a capacitor C5 becomes lower, and a Zener diode ZD1 and a transistor Q2 are turned off. As a result, a voltage is applied across the gate of a field effect transistor Q3. The apparent impedance between the source and drain of the transistor Q3 gradually drops from the turned-off state of the transistor Q3, and an electric current is supplied to a resistor R6. Therefore, the input current will not become sharp, but instead becomes continuous, and a higher harmonic components are reduced. When the temperature of a fluorescence lamp FL rises, the resistance value of the resistor R6 rises and reduces the flow-in quantity of the input current.
