Title: Re-imprinting method for semiconductor device
Inventor: SATO OSAMU
IPC: H01L23/544
Filed: 1986-04-01
Abstract: PURPOSE:To erase an imprinted part by laser readily and to make it possible to perform clearer imprinting again, by including a process for applying a thermosetting resin on the imprinted surface of a semiconductor device, a process for thermally hardening the thermosetting resin, and a process for laser imprinting on the surface of the thermally hardened resin. CONSTITUTION:In order to erase an imprinted part, a black thermosetting resin 3 is applied on the entire surface of the imprinted surface. Thus an affected layer 2a is coated and the imprinted part is concealed. Heat treatment is performed, and the thermosetting resin 3 is hardened. Laser light from a YAG laser imprinting unit is projected on an imprinted surface 4 of the surface of the thermally hardened resin. An affected layer 4a is formed at a part of imprinted characters. Thus re-imprinting is performed. The laser imprinting is performed as follows: the laser light is made to pass a character mask, which is provided in a light path; the laser light is formed in the shape of the beam in the character form; and said laser light is projected on the imprinting surface of the black thermosetting resin. Therefore, excellent contrast is yielded between the affected part 4a, on which the laser light is projected, and a part of the imprinted part4, on which the laser light is not projected.

IPC: B65B35/44
Filed: 1988-03-29
Abstract: PURPOSE: To arrange articles in a prescribed pattern for packaging by repeatedly applying a varying pressure to the surface of the article array and filling void space with articles. CONSTITUTION: An article arrangement apparatus 22 contracts moving articles to be packaged 18 in an article arrangement area 20 to the shape of a group 26 by intercepting articles 18 with a barrier 24. Articles 18 are collected in the arrangement area 20, and a void space 68 is formed. To prevent the generation of void space, side walls 58, 60 are placed movable along the length of the arrangement area. The side walls 58, 60 are driven reciprocally by their respective actuators and expand the article arrangement area 20 in the direction diagonal to the moving direction of the entire transfer plane 16. On the other hand, when the side walls 58, 60 return to the initial position, these walls contract the article arrangement area to the initial size. This reciprocating motion is repeated while the articles 18 are in the article arrangement area 20.

Title: Resonance type light deflector
Inventor: TAKADA TSUNEHISA
IPC: G02B26/10
Filed: 1994-04-14
Abstract: PURPOSE:To provide a resonance type light deflector capable of precisely processing image information in a resonant scanner. CONSTITUTION:In the resonance type light deflector 10, solenoids are loaded on both ends of a vibration shaft 26 supported by leaf springs 34a, 34b, 36a, 36b, and a mirror 28 is loaded on the center part. By supplying an AC current to the solenoids, the mirror 28 is rocked together with the vibration shaft 26, and a scanning beam reflected by the mirror 28 scans on a recording carrier. At this time, though force F3, F3' act alternately to magnets 24, 24a in the directions of A, B, since the phases of the magnets 24, 24a are aligned, and the AC current is synchronized with the phase, the magnets 24, 24a displace in the same direction synchronizing with each other, and the inclination of the vibration shaft 26 (mirror 28) is prevented. Thus, no wobble occurs in the scanning beam, and the image information is processed precisely.

Title: Mechanical seal for water pump
Inventor: FUKUCHI MARIO
IPC: F04D29/16
Filed: 1981-05-20
Abstract: PURPOSE:To improve sealing function of a mechanical seal for a water pump, by forming cooling-water passages in a pump shaft in the manner that they extend from the inner end of the pump shaft and is communicated to a gap between an impeller and a driven ring fitted on the pump shaft, and thereby cooling the sealing portion of a sheet ring and the driven ring. CONSTITUTION:Inside a pump shaft 4, there are formed cooling-water passages consisting of an axial passage 32 extending from the inner end of the pump shaft 4 to a position just below the inner end of a driven ring 6 that is fitted on the pump shaft 4 by a back plate of an impeller 2 and radial passages 34 extending from said position just below the inner end of the driven ring 6 to the outer surface of the pump shaft 4 where a gap 30 is formed between the driven ring 6 and impeller 2. These cooling-water passages are communicated to the gap 30. With such an arrangement, water drawn from the suction side of the pump and carried through the cooling-water passages 32, 34 cools the surroundings of the driven ring 6 while passing through the gap 30 and also cools the sealing portion of a sheet ring 16 and the driven ring 6 effectively, so that sealing function can be fulfilled satisfactorily.

Title: Compressor for video signal
Inventor: NISHINO SHOICHI
IPC: H04N19/59
Filed: 1990-03-26
Abstract: PURPOSE:To attain efficient compression even to a video signal arranged in non-matrix picture elements by combining an output of a code length assignment circuit and an output of a nonlinear quantization coding circuit and outputting the result to an output terminal. CONSTITUTION:A code length estimate circuit 7 calculates a code length of a differential video image Z subject to nonlinear quantization. Since the code length is sufficiently short, a code length assignment circuit 8 allocates sufficiently much data quantity to a code word resulting from a partial video image X subject to orthogonal conversion coding. Moreover, the data quantity is allocated adaptively to the partial video image X by the code length of the differential video image Z in this constitution. Since the partial video image X inputted to an orthogonal conversion coding circuit 5 and the differential video image Z have a same number of picture elements as those of an original video signal, the compression is implemented without increasing object picture element number.

Title: Power circuit
Inventor: KANEKO SUSUMU
IPC: H02M7/06
Filed: 1994-03-23
Abstract: PURPOSE:To eliminate the use of a power transformer and obtain a low-loss low-voltage power supply, by placing a capacitor in at least one of input lines. CONSTITUTION:A pair of power lines L1, L2 feed power from a commercial power supply 2 to a full-wave rectifying circuit 8. A capacitor C1 is placed in one L1 of the power lines. This makes it possible to keep the supply voltage, fed to the full-wave rectifying circuit 8, lower than the commercial power 2. Unlike conventional cases, low d.c. output voltage can be simply produced without a power transformer. Therefore, the use of a power transformer as a means for reducing a.c. voltage can be eliminated, which enables the simplification of the overall constitution and the reduction of power consumption and required space.

Abstract: PURPOSE:To use only one power supply for gate circuit for a plurality of GTO thyristors, by using a pulse transoformer as a means for detecting a voltage between the gate and cathode of the GTO thyristors. CONSTITUTION:When an off-gate signal (a) is inputted, a transistor TR7 turns on, a voltage is generated in the secondary winding of a pulse transformer 6, and a thyristor 6 turns on. Thus, an off-gate current flows between the cathode and gate of a GTO thyristor 1, the thyristor 1 turns off and a voltage VGK in which the gate is negative and the cathod is positive appears between the gate and the cathode. In this case, the voltage VGK is introduced to voltage detecting circuits 10-14, 21 and 22 through a pulse transformer 18 and a Zener diode 12, and the voltage detecting circuits output a positive voltage when the voltage VGK is a detection level or more. An FF15 is set with this signal and the output is zero, and the TR7 turns off. Thus, the thyristor 1 and the gate circuit can completely be insulated.
