Title: Closed motor driven compressor
Inventor: NISHIHARA HIDETOSHI
IPC: F04B35/04
Filed: 1988-06-15
Abstract: PURPOSE:To aim at reducing the number of parts by providing an inverter using a battery as a primary power source and delivering an a.c. current having a constant voltage/frequency ratio as a secondary power source, and by disposing a motor driven by the secondary power source and a compressing element in a closed container. CONSTITUTION:A battery 1 is used as a primary power source, and an inverter 20 delivers three-phase currents having the same voltage as the voltage of the primary power source and a frequency which allows a voltage/frequency ratio to be constant as a secondary power source by which a compressor body 21 is driven. Further, three-phase currents which are fed as the secondary power source from the inverter 20 are delivered to an induction motor 23 through an input terminal 28. Further, a rotor 25 is rotated while a slight slip is produced with respect to the frequency of the inverter 20 so as to drive a compressing element 26. Further, the induction motor 23 and the compressing element 26 are disposed in a closed container 22. With this arrangement, it is possible to eliminate the necessity of a position detector for a rotor 25 and a magnet rotor.

Title: Cooling tower using hydrophobic porous membrane and absorbing type temperature regenerator
Inventor: KUROKAWA HIDEAKI
IPC: F28C3/08
Filed: 1987-06-16
Abstract: PURPOSE:To prevent water drops from being dispersed out of a cooling tower by a method wherein heated cooling water is flowed in an area enclosed by hydrophobic porous membranes and air is forcedly flowed outside the membrane. CONSTITUTION:Cooling water heated by a device and a refrigerator and the like enters from a cooling water inlet 102 into a headet 104 of a membrane. Water entering the header 104 flows inside a hollow thread-like hydrophobic porous membrane 101 communicating with the header 104. Outside part of the hollow thread-like hydrophobic porous membrane 101 is fed with air by a fan 106 rotated by a motor 107. Thus, water within the hollow thread-like hydrophobic porous membrane 101 may generate water vapor through the membrane and its water temperature is decreased while it reaches to an upper header 105. The cooling water of decreased temperature is used again from a cooling water outlet port 103 for a cooling water for industrial product or a refrigerator and the like. In order to protect the membrane, a cover 108 is fixed. With this arrangement, since it is possible to take out only water vapor through the hydrophobic porous membrane, the water within the cooling tower is prevented from splashing out of the system as it is.

Title: Wafer cleaning device
Inventor: YAMAZAKI KAZUO
IPC: H01L21/46
Filed: 1990-06-07
Abstract: PURPOSE:To prevent the occurrence of electrostatic destruction without lowering the cleaning effect on the center of wafers by providing in series numerous cleaning water jetting ports, the jetting angles of which are continuously changed, to a cleaning water jetting nozzle. CONSTITUTION:A multipoint nozzle 3 with numerous serial cleaning water jetting ports is pivotally supported on a fulcrum XX above a wafer 1 which is turned on its center of gravity 0. The cleaning water jetting ports are continuously arranged from a point YY on the diameter of the water to one end ZZ of the diameter of the wafer perpendicular to the line 0-YY and the jetting angles of the jetting ports are continuously changed, with the angle being vertical at the point ZZ and being adjusted to an angle at which the cleaning water 2 can reach the point 0 at the point YY, and the cleaning water is jetted along the radius 0-ZZ of the wafer 1. The 4 in the figure is a cleaning water jet receiving surface on the surface of the wafer. Since the same quantity of cleaning water 2 is received by a wide cleaning water jet receiving surface at the central part of the wafer, the water pressure which the surface receives is reduced. The areas of the cleaning water jetted from the adjacent ports are overlapped upon another. At the time of carrying the wafer 1, the multipoint nozzle 3 is moved in the direction shown by the arrow F around the fulcrum, namely, the point XX.
