Patent JP-S62294328-A (JP)
Title: Current switch
Inventor: HAYANO SHINICHIRO
IPC: H03K17/693
Filed: 1986-06-13
Abstract: PURPOSE:To set an output voltage freely and to stabilize the titled switch to a current by dividing by a resistance a constant voltage generated across a diode so as to decide the output voltage. CONSTITUTION:A current I0 flowing to a constant current source 4 flows entirely through a FET 1 and the current is branched into a diode 5 and resistors 6, 7. A voltage VH appearing at an output terminal 12 is expressed as VH =-VDR6/(R6+R7), where VD is a voltage across the diode 5 and R6, R7 are resistances of the resistors 6, 7 respectively. Since the output voltage VH depends on the voltage VD across the diode 5, the voltage is made sufficiently stable against the change in the current I0. Further, the output voltage VH is decided freely by the ratio of the resistance of the resistors 6, 7.

Title: Collector for electron tube
Inventor: MURAYAMA YOUICHI
IPC: H01J23/027
Filed: 1983-07-29
Abstract: PURPOSE:To enable a collector to be used as a vacuum envelope for a long time by forming a hole penetrating an area located near each joint and installing thin vacuum-sealing plates outside the joints. CONSTITUTION:A collector is made by joining four parts consisting of base bodies 11 at joints 7. A sealing plate 9 having a small thickness and made of an easily deformable substance such as copper, a copper-nickel alloy, copal or SUS is fused to each base body 11 having at least one gas hole 10 by brazing. As a result, since vacuum sealing is achieved by the sealing plates 9, the collector can perform its full function as a vacuum envelope even when minute cracks or the like cause leaks to develop in the joints. In addition, the collector has a sufficient strutural strength and can stand prolonged repeated operation.

Title: Monitor for magnetic recording data on film in developing and film scanning device
Inventor: FARLING DUANE JAMES
IPC: G03B17/24
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To inform the necessity of cleaning a head before a data reading ability disappears by comparing the peak amplitude of a data/pulse signal with a specified threshold value, determining the deposition of a foreign object in a reading gap and giving a perceptive alarm. SOLUTION: When a magnetic reading head is in a clean condition where no foreign objects are deposited in a reading gap, the peak amplitude 62 of a detected data/pulse signal is within a range exceeding a threshold value VH. In this case, an LED is lit green to show correct detection of a signal from the magnetic layer of a film. If a foreign object is deposited, a peak signal level is lowered, an amplitude 60 is reduced to be higher than a threshold value VL but lower than the threshold value VH. In this condition, the green color disappears from the LED. Such perceptive display notifies an operator of a reduction in a signal level to clean a magnetic reading head. Thus, a necessary cleaning operation is performed for the head before a data reading ability is lost.

Title: Gas laser output apparatus
Inventor: TAKAGI SHIGEYUKI
IPC: H01S3/097
Filed: 1990-05-29
Abstract: PURPOSE:To make it possible to stably output a light beam without destroying semiconductor switching elements even if semiconductor switching elements conducts when the insulated state of discharge switching elements are not returned by connecting a protective conduction element having a maximum peak current smaller than the maximum peak current of the semiconductor switching element to a loop circuit formed of a primary coil of a pulse transformer, a power-supply capacitor and semiconductor switching elements. CONSTITUTION:Electric energy output from a reflecting circuit 2 is charged in a power-supply capacitor 3. If a thyristor 5 conducts in this state, a pulse current I flows mainly from a capacitor 3 to a loop circuit formed of a protective diode 22, a primary coil 4a and the thyristor 5. This pulse current I flows in to a secondary coil 4b thereof by the induction caused by a pulse transformer 4. Main discharged occurs between the main electrodes 9, 10 of a gas laser tube 8, causing a gas laser medium to be excited. Thus, light reflection occurs in a resonator, with the result that a light beam is output.

Title: Deuterium discharge tube
Inventor: OKAGAKI HIROSHI
IPC: H01J61/54
Filed: 1983-08-01
Abstract: PURPOSE:To obtain a deuterium discharge tube which requires only a low firing potential to start discharging by forming a conductive film having a surface resistance within specified range between the anode and the shielding case. CONSTITUTION:An anode 2 is fused (by electric welding) to the exposed portion of a lead-in wire 22 covered by glass 21; the lead-in wire 22 penetrates the bottom plate 3' of a shielding case 3 with an insulator 23 interposed. A part of the surface of the insulator 23 located above the bottom plate 3' is coated with a conductive film 24 consisting of one of tin oxide, Cr-SiO and Cr-N, so that the anode 2 is electrically connected to the bottom plate 3' through the conductive film 24. The thickness of the conductive film 24 is adjusted so that its surface resistance is in the range of 5kOMEGA-5MOMEGA. Owing to the above constitution, precedent discharge develops between the anode 2 and a pin hole 5. During this precedent discharge, a cathode 1 is heated to produce suspended thermions. Following that, discharge develops between the anode 2 and the cathode 1. Accordingly, discharge can stably be initiated with a low firing potential.

Title: Machining liquid nozzle for wire electric discharge machining device
Inventor: OBARA HARUKI
IPC: B23H7/02
Filed: 1987-06-05
Abstract: PURPOSE:To keep a machining groove in a normal state, by a method wherein a rotor, being rotatable around a wire guide serving as an axis, is mounted in a position in the vicinity of an exhaust nozzle in a nozzle, and a plurality of axial through-flow passages are bored in the rotor so that an inflow port and an outflow port are deviated from each other. CONSTITUTION:A rotor 9 is mounted in a position in the vicinity of an exhaust nozzle in a machining liquid nozzle. A rotor 9 is rotatable in a state that a central port 10 is inserted externally of a wire guide, and the odd number of through-flow passages 11, axially extended through, are bored between the upper and the under surface of the rotor. An inflow port 13 and an outflow port 12 are formed in a manner to be deviated in a direction of rotation, thus, through injection of machining liquid in the machining liquid nozzle, the rotor 9 is rotated at a high speed. Thus, when the one of the outflows 12 is positioned facing a machining groove, a pressure on a wire is changed, and a fine change in a pressure causes production of fine vibration, and prevents abnormal approach of the wire to the machining surface. This constitution enables execution of high speed machining, and keeps a machining surface in a normal state.

Abstract: PROBLEM TO BE SOLVED: To suppress sufficiently an environmental magnetic noise, even if disagreement of coil directions exists between compensating magnetic field generating coils, by muffling the environmental magnetic noise in a process for decomposing the noise into three components in the magnetic field generating directions of each three-dimensional coil. SOLUTION: A measured output of an environmental magnetic noise by a reference three-dimensional SQID (magnetic sensor for environmental magnetic noise measurement) 4 is transmitted to a decomposition-operation device 8 from SQID driving circuits 6a-6c through A/D converters 7a-7c. The decomposition-operation device 8 decomposes the inputted measured output respectively into the magnetic field generating directions of each coil 5x-5z of a three-dimensional coil 5, and calculates output values for feedback to each coil 5x-5z respectively based on obtained each decomposed output. The calculated output is transmitted to the three-dimensional coil 5 through D/A converters 9x-9z.  Each respective coil 5x-5z forms synthetically a magnetic field having the same size and the direction opposite to the environmental magnetic noise in a magnetic shield room inside which compensating magnetic field generating coils are installed, to muffle the environmental magnetic noise.
