Title: Gas valve opening/closing device
Inventor: HATA KENJI
IPC: F16K31/126
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain a proper opening with a simple structure by detaching a magnet from an attraction plate and opening a water supply automatic valve in the case that water flow pressure reaches a value for securing opening enough to ignition. SOLUTION: When water flow passage is increased from a stopped state, a spindle 3 is abutted against a water supply automatic gas valve 4 and reaches a position immediately before starting the opening. An attraction plate 6 is then engaged with an engagement part 8. When the water flow passage is further increased from this state and exceeds attraction force between a magnet 2 and the attraction plate 6, the magnet 2 is removed from the attraction plate 6. The attraction force, having disburbed proceeding of the spindle 3, is eliminated. The water supply automatic gas valve 4 is opened at once to the extent for securing a rate of gas necessary for ignition. Fuel gas from a gas inlet is ignited by electrodischarging of an ignitor, and burning is started by a burner 27.

Title: Wafer holding apparatus and method
Inventor: OKABE YASUNORI
IPC: B23Q3/15
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a wafer holding apparatus and its method for preventing stained particles with a positive charge from sticking and holding a wafer with strong attractive force. SOLUTION: A wafer holding apparatus includes an insulating member 1 in which an inner electrode 2 is buried, and a variable DC power supply 6 for applying a positive DC voltage to the inner electrode 2. When a wafer 11 is mounted on the insulating member 1, a positive voltage of, for example, about 300 V is applied to the inner electrode 2. In this way, a low positive voltage is applied to the inner electrode 2 in the insulating member 1 when the wafer 11 is mounted, and stained particles are kept away from the wafer. In addition, a self bias voltage caused by plasma can be added thereto when a high-frequency power is applied, thereby increasing the voltage applied to the wafer. Then, the wafer 11 is held surely with larger Coulomb force of attraction, and a yield in treatment of the wafer 11 can be improved.

Title: Prevention of scatter of water drip from exhaust tube in ac/dc type cooling tower and ac/dc type cooling tower provided with function preventing scatter of water drip
Inventor: KOMIYA JUJIRO
IPC: F28F25/04
Filed: 1988-08-30
Abstract: PURPOSE:To eliminate the scatter of water drips from an exhaust tube substantially by a method wherein water spray is supplied to the inner end of a heat exchanger from a plurality of cooling water guiding pieces extending from the bottom surface of an upper water tank, positioned above innermost water spraying bar, to the upper part of the inner end of the heat exchanger. CONSTITUTION:Part of cooling water in an upper water tank 1 is discharged from the group of water discharging holes onto the upper surface of a plurality of cooling water guiding pieces 14 while the discharged water is spread on the whole area of the guiding pieces while flowing along the upper surfaces of the guiding pieces 14 and is slid down from the peripheries of the same whereby the water is supplied and scattered onto the inner end of a heat exchanger B. As a result, the cooling water spreads to the whole of the heat exchanger B and the supplying amount of the cooling water to the inner end of the same becomes smaller than the supplying amount to the other parts of the heat exchanger B. A head from the peripheries of the guiding pieces to the heat exchanger is smaller than another head from the water spraying bar 12a to the heat exchanger whereby a possibility that the cooling water collides against the inner edge of the heat exchanger and becomes water drips may be reduced and the scatter of the water drips out of an exhaust tube shell 3 may be reduced. The cooling water guiding pieces are formed of one sheet of vinyl chloride film formed so as to have the shape of comb teeth.
