Filed: 1992-03-11
Abstract: PURPOSE:To simplify the adjustment of an optical head. CONSTITUTION:A laser beam outgoing from a laser diode 21 is converted to a parallel beams by a collimate lens 31. The parallel beams are reflected by a total reflection mirror 32 and reflected further by a beam splitter 33 and made incident on a magneto-optical disk 42 through an objective lens 41. The laser beam reflected by the magneto-optical disk 42 is incident on the beam splitter 33 through the objective lens 41 and the beam transmitting through the lens 41 transmits through a 1/2 wavelength plate 39 and a part of the beam is reflected by the beam splitter 34 and made incident on a photodetector 37. Further, the beam transmitting through the beam splitter 34 is reflected by the total reflection mirror 35 and made incident on the photodetector 38. From the difference of the outputs of the photodetectors 37 and 38, an RF signal corresponding to a signal recorded on the magneto-optical disk 42 is generated. The collimate lens 31, the beam splitters 33, 34, the 1/2 wavelength plate 39 and the photodetectors 36 to 38 are integrated in an alignment part 30.

Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To perfectly eliminate defects of an organic dielectric by dissolving an etched metal foil part not adhered to the organic dielectric film in the dissolving step. SOLUTION: In a first step an organic dielectric film 7 is adhered to an etched metal foil 6 so as to follow up its rough surface shape. A metal plate is faced at the front surface of the organic dielectric film 7 and it is electrolytically polished in a soln. to dissolve defects of this film 7 i.e., unadhered part 8 of the etched foil (10). Counter electrodes 9 are formed on the front surface of the dielectric film 7. The etched metal foil 6 uses Al, etc. The counter electrodes 9 are of a polypyrrole film formed by the chemical or electrolytic polymerization. Thus it is possible to perfectly eliminate the defects of the organic dielectric.

Title: Play system for japanese pinball hall
Inventor: OKAZAKI MAKOTO
IPC: B42D15/10
Filed: 1989-04-06
Abstract: PURPOSE:To prevent a reduction in takings of a Japanese pinball hall to the utmost by giving the priority to the lending motion of game goods based on the numerical information stored in a memory area over the lending motion of game goods based on the premium value information stored in an auxiliary memory area in a lending device. CONSTITUTION:A control unit 3 displays the total of numerical information N1 and N2 in the state where a magnetic card 5 having the numerical information N1 or premium numerical information N2 stored therein is inserted to the card inserting hole. When a ball lending switch 8 is operated to ON, pinballs within the range of the numerical information N1 is first preferentially lent through a ball lending machine body 2a, and the numerical information N1 is reduced by the lending number. The control unit 3 first lends pinballs within the range of the premium numerical information N2 through the ball lending machine body 21 only when the remainder of the numerical information N1 becomes zero, and reduces the premium numerical information N2 by the lending number. Thus, the encashment of a play card by a clearing device can be restrained to the utmost, whereby the improvement in takings of a Japanese pinball hall can be realized.

Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To realize a high resolution characteristic by a simple circuit. SOLUTION: A decoding section 1 decodes an image signal series VS and motion vector information MV from a signal BTS. A vector conversion section 2 and a pixel unit motion vector generating section 3 generate a motion vector PV in the unit of pixels based on the motion vector information MV. A coefficient setting section 4 sets values of mixture ratios K,1-K based on a scalar amount |PV| of a motion vector in the unit of pixels. A moving image interpolation signal generating section 5 generates a signal MS by in-field processing and a still image interpolation signal generating section 6 generates a signal SS by inter-field processing.  A coefficient weight section 7-1 multiplies the mixing rate K with the signal MS and a coefficient weight section 7-2 multiplies the mixing rate (1-K) with the signal SS and an adder section 8 sums both the multiplied signals and provides an output of an interpolation scanning line signal IP.
