Title: Compound dry vacuum pump
Inventor: OZAWA OSAMU
IPC: F04C25/02
Filed: 1994-11-24
Abstract: PURPOSE: To keep the required power characteristic approximately constant, regardless of an intake port pressure fluctuation, and avoid the occurrence of a trouble such as an over-compression state by forming a vacuum pump out of a pair of screw rotors and a pair of Roots rotors coaxially mounted on the tips thereof. CONSTITUTION: Sealed chambers 12 and 11 house a pair of screw rotors 5 and 6 as well as a pair of Roots rotors 2 and 3 coaxially mounted on the tips thereof. The rotors 5 and 6, and 2 and 3 are caused to rotate at a constant velocity in an opposite direction relative to each other on the operation of a motor 4, thereby drawing a fluid through an intake port 32 formed on an end wall 31 and discharging the fluid through an exhaust port formed on the external surface of another end wall 30. In this case, the required power fluctuation of the rotors 2 and 3, and the required power fluctuation of the rotors 5 and 6 have a characteristic opposite to each other relative to the fluctuation of intake port pressure. The required power characteristic of a pump as a whole is, therefore, maintained approximately constant over the entire pressure zone.

Title: Manufacture of semiconductor device and plasma cvd equipment
Inventor: SERITA ISAO
IPC: H01L21/318
Filed: 1989-11-09
Abstract: PURPOSE:To simply prevent the warping of a semiconductor substrate, the disconnection and contact of wiring, and obtain a uniform substrate free from strain, by supplying discharge frequency electric power of different frequencies, forming thin films with different stress directions on a semiconductor substrate, and controlling the total stress by alternately stacking the thin films. CONSTITUTION:By using plasma CVD method and changing discharge frequencies of high frequency power supplies 7, 8, thin films with different stress directions are formed on a semiconductor substrate 10. A thin film 12 generating compression stress and a thin film 11 generating tensile stress are alternately stacked, thereby controlling stress. When compression stress is generated, the substrate is bent so as to protrude outside. When tensile stress is generated, the substrate is bent so as to protrude inside. Hence, by combining both of the films, the stresses are cancelled, and the semiconductor substrate can be so controlled that external force is not applied. Thereby the generation of warp of the substrate, the disconnection of wiring on the substrate, and the mutual contact of wires can be prevented.

Abstract: PURPOSE:To prevent Joule heat from diffusing to a heat accumulation layer and to effectively use an applied voltage by so extending a thermal conductive layer having desirable thermal conductivity between the accumulation layer and heat generating resistors as to dispose the conductive layer under a gap to adjacent heat generating resistor. CONSTITUTION:A heat accumulation layer 2 is superposed on an insulating board 1 to cover the board 1, a thermal conductive layer 6 is so superposed as to dispose the forming positions of heat generating resistors 3 on the layer 2 under a gap to the adjacent resistor 3, and the layer 6 is covered with a protective layer 5.

Abstract: PURPOSE:To suppress the fuel cell stack voltage at low load by opening or closing cutoff valves provided in the upper and down flow side of the said fuel cell stack with the load output signal so as to increase or decrease the number of fuel cell stack connected in parallel. CONSTITUTION:When the output P of a fuel cell is lowered the current I is also decreased and as the result the voltage V is heightened. In a fuel cell when the voltage is heightened the deterioration of the electrode is induced, therefore it is necessary to control the voltage within a range hard to induce the deterioration. For the sake of this, the signal line 11 of the load detection circuit assembled in a power control device 10 is connected to the cutoff valve 5a-5d, 6a-6d, so the cutoff valves can be operated to ON or OFF corresponding to the load so as to cut off the gas flow to some of the fuel cell stacks 7a-7d and separate them fluid mechanically when the load is low. And some of the switches 12a-12d provided between the fuel cell stacks 7a-7d and the power output cable 9 can be opened by the signal on the signal line 11 so as the fuel cell stacks to be separated fluid mechanically are insulated also electrically from the main electric circuit.
