Title: Current lead
Inventor: KANEKO NORIO
IPC: H01L39/04
Filed: 1995-05-11
Abstract: PURPOSE: To detect the abnormality of a current lead itself occurring at current application at an early stage by attaching a light waveguide part to the conductor wire of a conductor, which constitutes a current lead, and allowing light to enter this light waveguide part, and detecting the change of intensity, wavelength, etc., of the light having come out. CONSTITUTION: An insulator 5 surrounds a conductor wire 3 and a light waveguide 4, and further these are attached to the supporter 2 lying at the roughly center of a hollow tube 1. And, at least one conductor consisting of such conductor wire 3 and the light waveguide 4 into the hollow tube 1 so as to constitute a current lead. Since the conductor wire 3 and the light waveguide 4 are positioned closely, if unequal partial heating occurs in the conductor wire 3, the light waveguide 4 is partially deformed, too, by the thermal expansion of the conductor wire 3. It becomes possible to detect the abnormality of the current lead itself at an early stage by optically detecting the deformation occurring in this light waveguide 4.

Filed: 1991-05-10
Abstract: PURPOSE:To realize accurate submicron processing by emitting parallel beams of ions and neutral particles to an object while changing the ion to neutral particle ratio. CONSTITUTION:A plasma chamber 20 and an etching chamber 22 are separated by a microchannel plate, and an ion control electrode 36 is provided on the side of the microchannel plate facing the etching chamber 22.

IPC: H04N1/04
Filed: 1988-06-01
Abstract: PURPOSE:To correct the dispersion in the sensitivity caused by the structural ununiformity of a sensor element by applying light irradiation to each sensor element sequentially. CONSTITUTION:A laser beam generator used for the 1st lighting 3 uses an output light of, e.g., nearly 10mW, and after the output from a sensor element of a photosensor 1 is detected by a detector 7, the relevant sensor element is irradiated by the correction of a difference with an object output level.

Title: Combustion detector
Inventor: OKAMOTO KENYA
IPC: F23N5/12
Filed: 1990-05-25
Abstract: PURPOSE:To detect the air ratio of an air-fuel mixture during combustion by a simple device and maintain a stable and favorable combustion condition, by using two monitor burners different in burner port diameter and utilizing the combustion characteristics of the two monitor burners. CONSTITUTION:Flow rate through a monitor burner 6 is constantly maintained at a fixed value by a flow control valve 5. The monitor burner 6 comprises two burners differing in burner port diameter. The larger diameter monitor burner 6 has a burner port diameter greater than the quenching distance, so that flash back occurs in the burner 6 at a fixed primary air ratio. Under variations in the primary air ratio, the smaller diameter monitor burner 6 suffers flash back if the burner port diameter thereof is greater than the quenching distance, and forms a lifted flame or a stable adhering flame if the burner port diameter is smaller than the quenching distance. Wire-nettings 9, 12 for stopping flash back are provided at lower parts of the burner ports of the monitor burners 6, to ensure stable combustion of a flash-back flame on the wire-nettings 9, 12. The position of a flame varies greatly according to whether the flame is a flash-back flame, a lifted flame or an adhering flame. The variation in the flame position can be detected by flame rods 10, 13. Therefore, the primary air ratio of an air-fuel mixture can be detected by the two burner ports 8 and 11.

Abstract: PURPOSE:To prevent the leak of the noise in a hose outside the hose and suppress the noise of the electrical cleaner hose by arranging a sound arresting material in spiral form on the inner surface of the hose and embedding the sound arresting material into the gap between the contiguous core parts on the inner surface of a flexible member. CONSTITUTION:A flexible member 12 is formed from a thin film form, e.g. soft vinylchloride film, and a sound arresting material 17 is arranged in spiral form on the inner surface 10b of a hose so that the gap (g) between the contiguous core parts 11 and 11 on the inner surface of the flexible member 12 is charged with the sound arresting material 17. The sound absorbing material such as urethane and felt or the sound shielding material such as lead sheet is used as the sound arresting material 17, and the inner surface 10b of the hose is formed into flat surface by making the thickness of the sound arresting material 17 equal to the thickness of the core part 11. Though, when an electrical cleaner is operated, the sucked air generates the air cut sound in the hose 10, the air cut sound is absorbed or shielded by the sound arresting material 17. Similarly, also the sucked sound, collision sound, etc., which are generated at a suction port, etc., and transmitted in the hose 10 are absorbed or shielded by the sound arresting material 17, and the leak outside the hose 10 is prevented.

Title: Amplifying output circuit
Inventor: SEKI KUNIO
IPC: H03F3/68
Filed: 1979-10-24
Abstract: PURPOSE:To improve the characteristics, by using the differential npn transistor circuit which applies the input signal to the emitter via the pnp transistor for the buffer amplifier and then setting the working voltage at about half of the power supply voltage to obtain the intermediate voltage produced by the first-stage amplifier and at the DC output level. CONSTITUTION:The input Vin and OV are applied to the differential circuit consisting of the npn transistors Q33 and Q34 from the emitter side and via the pnp transistors Q31 and Q32 each, and thus the signals having the positive and opposite phases to the signal Vin are produced (buffer amplifier 5). The intermediate-stage amplifier 1 is formed with pnp type Q41 and npn type Q41, and the output of the amplifier 1 is applied to the driving stage amplifiers (Q44 and Q45). Then the Q49 and Q50 of the PP circuit 3 are driven to obtain the output OUT1 having the opposite phase to the input. At the same time, the positive phase output OUT2 is obtained from the positive phase output V1 of the buffer amplifier 4 via the amplifiers 1'- 3', thus driving the load SP by the difference between the outputs 1 and 2. In such constitution, the distortion factor can be reduced, and the output intermediate voltage can be set with the output current level of the buffer amplifier. Thus the circuit can be simplified.

Title: Electronic part cooling device and manufacture thereof
Inventor: TASAKA MASAHIRA
IPC: H01L23/467
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent an electronic part cooling device from deteriorating in thermal conductivity, by a method wherein vanes which agitate cooling fluid in a temperature boundary layer near the heat dissipating surface of an electronic part are held in a movable manner above the heat dissipating surface and driven to swing. SOLUTION: An air layer rises in temperature by heat released from a chip 1 mounted on a board 16, and a temperature boundary layer 15 is gradually increased in thickness from the upper end to lower end of a heat dissipating surface 2. The temperature boundary layer 15 gets thicker with a decrease in the flow speed of a cooing air, and the heat dissipating surface 2 deteriorates in thermal conductivity with an increase in the thickness of the temperature boundary layer 15. The temperature boundary layer 15 is lessened in thickness so as to prevent the heat dissipating surface 2 from deteriorating in thermal conductivity, so that the temperature boundary layer 15 is agitated at a point nearest to the heat dissipating surface 2 so as to get the above object.  Many movable vanes 3 are installed on the heat dissipating surface 2 and swung, whereby the temperature boundary layer 15 is stopped from being developed and broken by the vanes 3, and the heat dissipating surface 2 can be restrained from deteriorating in thermal conductivity.
