IPC: H05B6/32
Filed: 1981-04-13
Abstract: PURPOSE: To improve the symmertry of the temp. distribution of a device for growing a single crystal with high frequency heating by holding more than half of the winding of a coil on the same horizontal plane with ends of the coil.  
     CONSTITUTION: In a coil composed of a lead wire 1, ends 2 and a winding part 3, one or both of the ends 2 hold more than half of the winding part 3 on the almost same horizontal plane, so the influence of the upper and lower ends of the coil due to the termination of the coil on the symmetry of a magnetic field is minimized, and lines 6 of magnetic force produced by an electric current 5 have enhanced symmetry. In the figure, 4 is a section of the coil. Accordingly, the symmetry of the internal temp. distribution of a furnace heated with the high frequency magnetic field is enhanced. It is effective that the inclined part 7 is made oblique or perpendicular even at the intermediate part and the part 7 is held on the same horizontal plane every winding.

Title: Testing method for bidirectional series transciever and circuit for conducting this method
Inventor: RORAN MARUBO
IPC: H04L1/24
Filed: 1992-03-13
Abstract: PURPOSE: To test a tranceiver which operates at extremely high frequency without generating disturbance by comparing a transmit control signal with a receive signal supplied by an amplifying means of the tranceiver. CONSTITUTION: A tester 15 sets a signal INF of a transistor(TR) 12 to be tested to zero. The tester 15 commands the tranceiver 12 to send one group of data applied to parallel inputs of a serializing-nonserializing circuit 14 next. The circuit 14 converts those data into serial data and sends them to the tranceiver 12. The amplifier of the tranceiver 12 receives the transmit control signal (e) and actuates a current generator G1. A line is not connected, so a current source S1 feeds a current to only matching impedance R of an active channel. A voltage developed at a reception terminal V of the amplifier 1 regenerates the transmit control signal 8e), which is received by the tester 15. The tester 15 compares the sent parallel data with the received parallel data.

Title: Eddy current damper
Inventor: HIRAKAWA YASUYUKI
IPC: H02K49/06
Filed: 1994-02-16
Abstract: PURPOSE:To make it possible to radiate heat from a magnet promptly for a short time during control, by forming a cylindrical rotating body with an opening with an air-flow receiving plate on one side and a bottom part with a plurality of air holes and an air blower on the other side. CONSTITUTION:A blower 20 that rotates with a rotating body 1 has a fin with an opening in a forward rotating direction and a closed end on the other side. When the rotating body 1 rotates, cooling air flows into an air hole 1b to cool an electromagnet 4. The air hits on an air-flow receiving plate, flows into a cooling fin 1d in a rotating body 1 and is discharged outside into the open air. A semicircular bent part 30a is formed at an air-flow receiver 30 so that the cooling air from the blower 20 is thrust into the cooling fin 1d and discharged outside through centrifugal force of the cooling fin 1d. As a result, the heated air radiated from the electromagnet 4 is discharged outside in a short time.

Title: Etching
Inventor: SHIRAISHI HITOSHI
IPC: H01L21/302
Filed: 1993-03-17
Abstract: PURPOSE:To etch selectively an N-type amorphous silicon film to an undoped amorphous silicon film by a method wherein an etching is performed at a plasma discharge region of a high pressure using specified reactive gas not containing oxygen gas. CONSTITUTION:An etching is performed at a plasma discharge region of a high pressure of 15 pa or higher using chlorine gas, which does not contain carbon atoms or fluorine atoms, as reactive gas 17. Thereby, as a chemical surface reaction effect due to a radical becomes dominant, a difference between a conduction electron concentration in an N-type amorphous silicon film 14 and a conduction electron concentration in an undoped amorphous silicon film 13 appears as a difference between an etching rate in the film 14 and an etching rate in the film 13 by the property of a chemical surface reaction. Accordingly, the film 13 is hardly etched and the film 14 is selectively etched.

Abstract: PROBLEM TO BE SOLVED: To lower the flow rate lower limit measurable by a fluidic element. SOLUTION: A nozzle 5 communicating with a fluid vibration space is formed in a square cylindrical shape surrounded by a pair of opposed planes 2, 3 parallel along the flow of a fluid and a pair of side walls 15, 16, the lateral width W1 of one parallel opposed plane 2 located at a pressure inlet of a pressure sensor 12 for detecting fluidic vibrations is set greater than the lateral width of the other parallel opposed plate 3, and the side walls 15, 16 are tapered. Thus the flow rate of the fluid flowing in the nozzle 5 and draining into the fluidic vibration space 6 increases in the vicinity of the pressure inlet to result in a great pressure change due to the fluidic vibration near the pressure inlet, thereby lowering the flow rate lower limit measurable by a fluidic element 1.
