Title: Manufacture of commutator for motor
Inventor: NAYA YUUICHIROU
IPC: H01R43/06
Filed: 1984-12-07
Abstract: PURPOSE:To obtain a commutator in which adjacent conductors are insulated by wavy grooves by flame spraying conductive metal over the entire periphery of a cylinder, forming a conductor to become a segment, and then cutting to remove a projecting strip. CONSTITUTION:A conductive layer 15 is formed by metallizing conductive metal by plasma metallizing over the entire periphery of a cylinder 10 formed with a wavy pro- jecting strip 18. Subsequently, the strip 18 is cut and removed to form nonconductive groove 18a. Thus, when the strip 18 is removed, a conductive portion 15a to become a segment insulated by the groove 18a is formed. Then, a conductive metal plating layer 19 is formed at the upside of the layer 15a by removing the groove 18a. Thus, a commutator in which adjacent conductive portions (corresponding to segments) are insulated therebetween by the wavy groove can be obtained merely by cuttint to remove the strip.

Title: Variable delay circuit
Inventor: NAKAMURA HIDEKI
IPC: H03K5/135
Filed: 1984-12-06
Abstract: PURPOSE:To attain a continuous change of the delay time of a signal having a wide band by controlling the time difference between the input and output analog signals with a control signal. CONSTITUTION:An A/D converter 1 converts an input analog signal into a digital signal, and a shift register 2 at the (n) stage delays the digital signal converted by the converter 1 by an (n) multiplies as much as a clock period. While a D/A converter 3 converts the delayed digital signal into an analog signal. A VCO4 delivers the clocks having frequencies changed by the control signal to the converter 1, the register 2 and the converter 3 respectively. Thus the delay time can be changed by the control signal and the delay time can be changed continuously for a signal having a wide band.

Title: Inspection method of wafer carrier
Inventor: YODA TADAYOSHI
IPC: H01L21/66
Filed: 1990-09-27
Abstract: PURPOSE:To prevent lowering of yield caused by deterioration of a water surface by carrying out ultrasonic cleaning, by measuring concentration of a specified substance which is dissolved out in cleaning solution and by judging whether or not a wafer carrier can be used. CONSTITUTION:Chemical containing fluorine such as hydrofluoric acid is often used for chemical cleaning of a silicon wafer, and a surface of the wafer is apt to be affected by fluorine; therefore, it is judged whether or not a wafer carrier can be used continuously by knowing how much fluorine is absorbed to the wafer carrier in use. Concentration of fluorine ion can be measured based on photoabsorption degree of sample liquid by adding Arfvedson's reagent to the sample liquid and by irradiating light of a wave length of about 620nm thereto. The method enables prevention of lowering of yield caused by deterioration of a wafer surface contained in the wafer carrier caused by chemical absorbed by the wafer carrier.

Title: High-pressure discharge lamp and lighting system
Inventor: HONDA HISASHI
IPC: H01J61/073
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce sputtering in glow/arc transfer, to shorten transfer time and to miniaturize a lighting device by lowering starting voltage. SOLUTION: A power supply conductor 2 sealed at both the ends of a translucent discharge container 1 is constituted of a sealing part 2a and a halide- resistant part 2b and an electrode 4 disposed at a tip of the power supply conductor 2 is mainly constituted of a plate. The electrode 4 can be compactly constituted for an increase in surface area by curving the plate part around a shaft of the power supply conductor 2 in a cylindrical shape, for instance. As a result, because surface area of the electrode 4 is increased and electrode surface current density is lowered, sputtering is reduced. By making it possible to reduce heat capacity of the electrode 4, glow arc transfer time is shortened. Further, electron radiation performance is improved and starting voltage is lowered by an edge effect by an edge at an end face of the plate of the electrode 4.

Title: Action switching device for ventilating fan
Inventor: KAWASAKI MASAHIKO
IPC: F24F7/007
Filed: 1987-10-14
Abstract: PURPOSE:To perform easy and accurate remote control of a ventilating fan, by a method wherein a plurality of kinds of half-wave phase control signals having different phase control angles are switched and sent from a switch at hand, and through discrimination of the signals by means of the ventilating fan body side, the action of the ventilating fan is switched. CONSTITUTION:In a switch 2 at hand, a signal of one polarity of an AC source waveform is received by a source circuit 2-1 through a rectifier 3-2 in a control circuit 3 to feed a power source as a DC source to a half-wave phase control circuit 2-2. A signal of the other polarity is sent to a pulse converting circuit 3-1 in the control circuit 3 on the ventilating fan 1 body side through change-over of a change-over switch 2-3 and regulation of a phase control angle theta1 of a half-wave phase control circuit 2-2. The control circuit 3 detects the control angle theta1, and the switching speed of the connection of a motor 4 for the ventilating fan is regulated. The switch 2 at hand is connected to the control circuit 3 through two electric wires, and since a switching element 2-2a tor controlling a phase in the half-wave phase control circuit 2-2 and a gate drive circuit 2-2b separate a polarity of a signal from a polarity of a power source, a signal by means of which the action of the ventilating fan 1 is switched can be accurately sent.

Abstract: PURPOSE:To prevent noises in an output signal, by a constitution wherein the channel potential of an MOS transistor provided in a signal charge output part is higher on the side of a drain and lower on the side of a source. CONSTITUTION:Diffused regions 3 and 4 are a source and a drain, respectively in an MOSFET. In this MOSFET, a width d2 of a signal output part 20b is narrower than a width d1 of a signal tJansfer part 20a, in which a transfer gate 5 is provided, in an embedded cahnnel 20. Parts 20c and 20d, where the diffused regions 3 and 4 are formed, respectively, have the width d2. The width of a position, where a part 20e, at which a reset gate 8 is provided' is coutnued to the part 20c, T is d33. The width d3 is narrow. In the region 20e, as the channel width becomes narrower, the channel potential becomes lower. The signal charge from the region 20e all moves to the region 20d aud does not leak to the region 20c. Therefore, noises are not generated in the output signal from a terminal 9.
