Title: Dc power unit
Inventor: MURAKAMI YOICHI
IPC: H02M3/28
Filed: 1986-07-18
Abstract: PURPOSE:To prevent impression of surge voltage on a rectifying diode and to reduce the power loss in the diode, by providing a magnetic amplification circuit between the secondary winding of a transformer and the rectifying diode to block the surge voltage. CONSTITUTION:A magnetic amplification circuit 15 is provided between the secondary winding of a transformer 5 and a rectifying diode 8. In case the surge voltage is generated from the primary power source 1, an input voltage detection circuit 13 detects the increase of the surge voltage and actuates a power amplification circuit 14 to impress the voltage applied in the direction of non-saturated state inverted from the saturated state of flux up to now of the magnetic amplification circuit 15. Thus the impedance of the magnetic amplification circuit 15 is enlarged so quickly that the power transmission through a diode 8 is not performed any more.

Title: Method for detecting terminal joint part
Inventor: HATTORI YOSHIYUKI
IPC: G01B11/04
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a terminal joint part detecting method of accurate and good operativity, wherein no final visual observation for confirming a terminal joint part is required. SOLUTION: While a process wherein a crimp-style terminal 13 is press- attached to an electric line 70, is repeated, the crimp-style terminal 13 forming mark parts before/after a terminal joint part moves to a holding member 50. The mark part is, through a green filter 22, imaged with a monochrome camera 20 to be detected as a dark part, and then image-processed with an image processing device 30, for issuing an alert from an alert device 40. Since, based on the alert, the specified numbers of crimp-style terminals 13 are processed before a terminal joint part is supplied to a press-attaching device 60, the crimp- style terminals 13 on both sides of the terminal joint part 11 is dummy-pressed with the press-attaching device 60. Thereby, press-attaching of a defective crimp- style terminal 13 to the electric line 70 is surely and easily avoided.

Title: Prism array measuring apparatus
Inventor: OGUMA NOBUO
IPC: G01M11/00
Filed: 1983-09-16
Abstract: PURPOSE:To measure a prism accurately with clarification of direction of reflection by which an image is developed, by installing a filter changing tones in a parallel direction of rectangular prism between collimeter optical system and prism array position. CONSTITUTION:A ray of light flashed from a lamp 1 enters into rectangular prisms 6a-6d of a prism array 6 after passing through cross wires 2, beam splitters 6a-6d, collimeter lens 4, and filter 15 and reaches a screen 5 passing through a path along the opposite direction. The thickness of the filter 15 changes steplessly in the longitudinal direction of the prism array 6, consequently, by the difference of densities of a screen image 5, it can be judged which reflection plane has caused development of the image. Therefore, plane angle A, perpendicularities of B, C and deviations of planes from their specified positions can accurately be measured.

Title: Electronic information equipment
Inventor: MORI SHIGEKI
IPC: G06F3/023
Filed: 1991-07-10
Abstract: PURPOSE:To input the information of different formats with a simple operation. CONSTITUTION:Character and code data for one picture are read out in a step S1 and whether the inputted data are reserved word data or not is successively scanned in a step S2. When the data are reserved words, the proper format and item of the data are identified in a step S3 and a buffer having the proper format is prepared based upon the identified results in step S4. Then a step S5 identifies the division of character string data started from the reserved word and a step S6 registers the character string data in the item of the buffer with the proper format. When there is no reserved word, a step 7 judges whether a buffer is formed or not, and when the buffer is formed, a step S8 checks data in the buffer. When the data are OK, a step S9 copies the data of the buffer to the mode area of the format.

Abstract: PURPOSE:To facilitate the retention of air tightness, simplify the work of inspection and permit preheating efficiently by a method wherein a molten metal discharging chamber is kept in inert gas atmosphere upon tapping and a vacuum gate valve is opened to move a trough from a preheating chamber to a trough chamber while the trough chamber is pivoted as a furnace body is tilted to tap the molten metal into the trough and discharge it. CONSTITUTION:Upon tapping, inert gas is conducted into a molten metal discharging chamber 10 to retain the atmosphere in the molten metal discharging chamber 10 in inert condition. Next, the inside of a vacuum chamber is retained in the slightly pressurized condition of inert gas and a vacuum gate valve 12 is opened to move a trough 7 by a slide bar 17 from a preheating chamber 11 to the position of dotted line. Then, the preheating chamber 11, the trough chamber 9, the vacuum gate valve 12 and a trough chamber part 16 are pivoted together with the tilting of the furnace body while keeping airtight condition. On the other hand, molten metal, tapped from a tapping hole by the tilting of the furnace body, is guided by the trough 7 and is discharged out of the molten metal discharging port 15 of the molten metal discharging chamber 10 and, thereafter, is treated in a molten metal treating chamber, connected to the molten metal discharging port 15.

Title: 1-junction superconducting quantum interferometer and its driving and detecting method
Inventor: IWATA YUJI
IPC: G01R33/035
Filed: 1989-07-03
Abstract: PURPOSE:To improve high-frequency follow-up performance and reduce noises by supplying in-phase bias currents to an rf-SQUID and a tunnel type Josephson junction(JJ) and applying a magnetic field to a SQUID loop by using a feedback coil so that magnetic flux variation by the variation of an external magnetic field is canceled. CONSTITUTION:A high frequency power source 19 supplies the in-phase bias currents Ib and Id to the rf-SQUID 7 and JJ 20 and when the SQUID 7 has transition, fast pulses are generated by a squid ring. The pulses are converted by a resistance 21 into a current, which is supplied to the JJ 20 and exceeds the critical current of the JJ 20, so that a voltage is generated between both its ends. The generation probability of the voltage is set to 0.5 and the external magnetic field is inputted from a detection coil 10 in this state and applied to the squid 7, so that the generation probability of the voltage deviates from 0.5. This deviation is detected by comparison with a reference value and nega tive feedback is provided through the feedback coil 32 to detect current varia tion required to return the probability to the original state of 0.5, thereby detecting the variation of the external magnetic field.

Abstract: PURPOSE:To improve sorting performance by dispersing a raw material fed from a hopper with a compressed air sprayed from an air nozzle and to sort heavyweight articles from lightweight articles only with air and by generating a spiral upward flow and elevating spirally the lightweight articles. CONSTITUTION:When a raw material is fed to the one end part of a raw material carrying pipe 4 from a raw material feeding hopper 5, deposits on the raw material is blown off with a compressed air blown out from an air nozzle 6 and the raw material is dispersed thereby and is fed into a cylindrical part 1a of an inner cylinder 1 from a raw material feeder 3 with a suction air. As the upper part of the inner cylinder 1 becomes the upper end opening part of the cylindrical part 1a and is opened and the lower part becomes a cone- shaped bottom part 1b and is narrowed in its diameter, a spiral upward flow of the air is generated. As the result, lightweight articles are elevated by being accompanied with the air and are flown out toward the outer cylinder 2 and on the other hand, heavyweight articles are dropped down on the bottom part 1b by their weight and are discharged out of the machine from a discharging pipe 1c.
