Title: Valve device and valve assembly combining valve device units
Inventor: OKAZAKI TATSUO
IPC: F16K41/12
Filed: 1989-02-13
Abstract: PURPOSE:To give no influence to the operation of a valve by providing a hollow valve case in which valve seats are formed, a valve shaft to whose one end a valve body is fixed, a flexible diaphragm to seal one side of the fluid passage in the above case, a reinforcement member, and a driving device. CONSTITUTION:In the fluid passage 5 inside a valve case 2, a valve shaft 7b to which a valve body 7a to open and close valve seats 6a and 6b is fixed is inserted, and the valve shaft 7b is fixed liquid-tight to a diaphragm 8 consisting of a flexible material such as a rubber to seal one side of the fluid passage 5, and held to reciprocate in the axial direction of the passage 5 freely. By the rotation of the cam member 10 of a driving device 9, the shaft 7b is reciprocated. In this case, The diaphragm 8 goes on and goes back to the passage 5 side while being bent making the peripheral fixing part as the fulcrum, and since it receives a strong water pressure when the valve body 7a opens the flow way at the diaphragm 8 side, a reinforcement member 12 is provided at the outer side of the diaphragm 8. By such a constitution, there is no sliding part with the valve body 7a, and the shaft 7b does not go in or out of the passage 5.

Abstract: PURPOSE:To prevent the occurrence of short circuit of heater element wires beforehand when diffusing treatment and the like are performed for the wafer of a semiconductor device by arranging and providing a short circuit preventing member formed of an insulating material in parallel with an axial center between a process tube or a soaking pipe using non-insulating material and a heater. CONSTITUTION:A short-circuit preventing member 7 is provided between a heater 3 and a process tube 1 comprising a non-insulating material. A heat resisting insulating material is used for the short-circuit preventing member 7. The member 7 is arranged so as to surround the entire body of the process tube 1 in the heater 3. A plurality of wafers 10 as the materials to be treated are conveyed into the process tube 1. A port 1a of the process tube 1 is closed with a cap 8. The temperature of heater element wires 4 is increased so that the treating temperature becomes the specified temperature. Since the short- circuit preventing member 7 surrounds the entire source of the process tube 1, the short-circuit preventing member 7 serves the role of a soaking pipe. Thus, a treating chamber 2 of the process tube 1 is uniformly heated as a whole.

Filed: 1993-02-23
Abstract: PURPOSE:To change over a flow passage easily by arranging a cylindrical valve body in a non-slide hole movably between a first seal position for sealing the through-hole of a nozzle and a second seal position for sealing a valve body slide hole. CONSTITUTION:A valve body 10 is moved between a first seal position for sealing a nozzle 8 and a second seal position for sealing a valve body slide hole 4 by the slide of a supporter 11. When the valve body 10 stays on the first seal position, water flowed in from a flow entrance 6 is folwed out from a flow exit 7 through a non-slide hole 5 and the valve body slide hole 4 and when it stays on the second seal position, water is flowed out of the nozzle 8 through a through-hole 8a. The valve body 10 is moved by forming the non- slide hole 5 in the change over time of the flow passage without the sliding contact of O rings Oa, Ob with the nonslide hole 5. Therefore, a flow passage can be changed over easily without being affected by scales when the valve body 10 is moved.

Title: Lead wire excellent in solderability
Inventor: SATO MASAHIRO
IPC: H01R43/02
Filed: 1992-01-23
Abstract: PURPOSE:To prevent the generation of foreign matter by forming on a metal wire a semi-gloss solder-plated layer in which a lead particle is broken in parts to increase a solder wetting rate and prevent the generation of cracks. CONSTITUTION:The lead particle of a semi-gloss solder-plated layer 2 is smaller than those of a glossless solder-plated layer and a conventional semi-gloss solder- plated layer and also is dispersed over a wide range. A diffusion rate at the time of soldering is increased to increase a soldering effect because of the fineness of the particle, and a solder wetting rate (zero crossing time) is increased after a pressure cracker test and a heating test at a constant temperature and a constant humidity. Also, the Vickers hardness of the semi-gloss solder-plated layer 2 is harder as compared with the gloss-less solder-plated layer because of the fineness of the particle, so that the foreign matter of a solder is hardly generated in the process of manufacturing electronic components.

IPC: H03H17/06
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of an FIR type digital filter to be used for a QPSK modulator composed of hardware. SOLUTION: Two outputs symmetric to the center of a shift register 101 are inputted to product sum circuits 201 and 202 and multiplied with respective tap coefficients and the results are added. Further, the final output is provided by adding the results (including the multiplied value of tap coefficient of the center tap D0 in the case of even-number taps) through an adder 301. Since the multiplication at each tap of a roll-off filter for QPSK modulator and the added result on the first stage are replaced with the change in the code of the tap coefficient or with '0', the product sum circuits can be composed of two selection circuits and an EX-OR gate for generating their select signals.
