Title: Etching method for forming superconductive circuit
Inventor: NAKAGAWA HIROSHI
IPC: H01L39/24
Filed: 1985-06-03
Abstract: PURPOSE:To improve the workability by using magnesium oxide as an etching stop layer arranged between the layer to be subjected to the dry etching using carbon fluoride gas and the underlying layer not to be affected by the etching. CONSTITUTION:A magnesium oxide layer 11 is formed on a substrate 10 and a superconductive layer 12, for example, of Nb is formed. Subsequently, it is etched by carbon fluoride gas OF4. At this time, if device internal pressure of the high-frequency plasma discharge device is made 200mTorr on high pressure side, an etching rate of Nb becomes not less than 300Angstrom /min approximately, but the etching rate of MgO becomes at most about 1-2Angstrom /min. Accordingly, dry etching stops at the MgO layer 11 surely and a ground plane 13 of a desired pattern can be obtained. After forming an SiO2 film 14, the MgO layer 15 as an etching stop layer is formed and an opening 16 is then formed continuously with said insulating film 14 penetrated through. The etching process of the MgO layer 15 at this time can be made easily by making the internal pressure of chamber about 20mTorr on low pressure side.

Title: Segment detecting method for drawing input device
Inventor: TAKANO HIROSHIGE
IPC: G06T7/00
Filed: 1995-05-19
Abstract: PURPOSE: To precisely recognize parallel lines even if they are close to each other. CONSTITUTION: In a step S1, an area to be recognized from image information and the direction of a segment are set. In a step S2, the frequency distribution (histogram) of an image in the set direction in the set area is generated. In a step S3, the positions of peaks of the histogram are detected and the mean width of the peaks is found. In a step S4, a histogram is generated in an area which has the same height as the original height and is as wide as one peak at a right angle to the direction wherein the segment is detected. Then, a straight line is detected from two orthogonal histograms in a step S5 and data on it are stored in a memory. In a step S6, it is judged whether or not the straight line is detected as to all the peaks, and in case of 'YES', the process advances to a step S7 to output the start and end point coordinates of the straight line.

IPC: B23Q1/54
Filed: 1977-10-08
Abstract: PURPOSE:To automatically feed a discshaped workpiece into a head-stock chuck. CONSTITUTION:A swiveling arm 23 is set to swirl between a disengage point PO and a feeding point P3. The swiveling shaft line of the swiveling arm 23 is slightly inclined within the vertical plane, and a workpiece W that is held through absorption on the holder plate 53 is carried toward the headstock chuck 15 as the swiveling arm 23 swivels.

Title: Refrigeration cycle system
Inventor: OHATA YOZO
IPC: F25B1/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce leak current of a compressor in a refrigeration cycle system comprising a plurality of enclosed compressors connected in parallel and using an HFC refrigerant of higher pressure than R22, e.g. R410A, and a synthetic oil. SOLUTION: When an inverter power supply is employed as the drive power supply for a compressor, the power supply frequency contains a large quantity of high frequency components (carrier frequency) on the order of several kHz which is significantly higher than 50-60 Hz of commercial power supply thereby increases leak current easily. When at least one 1b of two compressors 1a, 1b connected in parallel is arranged to be operation controlled with commercial power supply, total leak current of the compressors 1a, 1b can be reduced as compared with a case where both compressors 1a, 1b are operation controlled with an inverter power supply.

Abstract: PROBLEM TO BE SOLVED: To avoid the danger to the human body of signal light leaking out when a light beam path is broken and to eliminate the influence on other light beam paths by cutting off only the signal light of the broken light beam path. SOLUTION: Signal light which is inputted to the optical amplifying and distributing device 1 is optical amplified by an optical amplification part 2, distributed by an optical distributor 3, and outputted from an optical output port 5 through a safety mechanism 4.

If an optical connector is disconnected or the light beam path is cut to break the light beam path, the reflected return light of the light beam path abruptly increases.  The reflected return light is demultiplexed by the optical coupler of the safety mechanism 4 and converted into an electric signal and the control part places the light shield part in operation to break the optical path.

Title: Magnetic processing device for fuel
Inventor: MAEDA TOMONOBU
IPC: F02B3/06
Filed: 1989-05-15
Abstract: PURPOSE:To improve fuel consumption by leading fuel oil to the space between an outer case and a permanent magnet, and a spacer through the groove in a cylindrical spacer and the hole in a spacer to increase the level of fuel oil gradually, and applying magnetic processing for a prescribed time. CONSTITUTION:The fuel oil (gasoline, light oil, heavy oil, etc.) flowing from a fuel tank through an elbow 13 and a pipe 12 passes through the groove 8a in a cylindrical spacer 8 and a hole 10a in a spacer 10 and goes into a space 11 to increase its level gradually to be subjected to magnetic process by a magnet 9. Since it takes a considerable time to make fuel oil flow out of the elbow 14, fuel oil is subjected to a sufficient magnetic processing. Since fuel flows in and out from the above, it is always in a full condition, and there is no possibility of air invasion and rusting due to water. It is thus possible to improve fuel consumption rate and decrease black exhaust smoke from a diesel engine.
