Title: Copy prevention device
Inventor: MIYOSHI AKIO
IPC: G06F21/12
Filed: 1989-08-18
Abstract: PURPOSE:To effectively prevent an illegal copying by providing plural illegal copy decision means in correspondence with event generation means generating events with a prescribed probability. CONSTITUTION:An illegal copy deciding part 1 has plural illegal copy decision means 1a-1n which independently decide whether the copy is illegal or not. An event generation part 2 similarly has plural event generation means 2a-2n and they independently generate the events with the prescribed probability. An abnormal action generation part 3 decides which is the illegal copy among illegal copy decision means 1a-1n and generates an abnormal action when the event generation means corresponding to the means which executes the decision generates the event with the prescribed probability. Thus, the illegal copy can effectively be prevented.

Title: Loud speaker device
Inventor: YOSHIKAWA AKIRA
IPC: H04R1/02
Filed: 1981-12-26
Abstract: PURPOSE:To improve frequency characteristics, by equipping a lateral frame which has outer circumferential surfaces in contact closely with respective internal surfaces of a baffle plate, both side plates, and a back plate, and a longitudinal frame which has outer circumferential surfaces in contact closely with internal surfaces of a bottom plate and both side plates nearly at the center height of a box body. CONSTITUTION:A loud speaker device consists of the speaker box 1, holes 2-5 for fitting speaker units, a port 6, a reinforcing lateral frame 7, and a back cavity 8 for a tweeter and a mid-range speaker. In this speaker device, while the plane surrounded with respective frame materials of the longitudinal frame  12 is held parallel to the baffle plate 11, outer circumferential surfaces of the  longitudinal frame 12 are brought into contact with respective inner circumferential surfaces of both side plates 10 and the reverse surface of the reinforcing  lateral frame 7. This reinforcing frame 12 increases the resonance frequency  and the deformation of the bottom plate 9 is suppressed more than that of the  baffle plate 11.

Title: Flexible coupling type supporting apparatus and biaxial freedom-degree gyroscope having same apparatus
Inventor: TSUKAGOSHI YASUO
IPC: G01C19/18
Filed: 1989-08-18
Abstract: PURPOSE:To improve the tuning property of a biaxial freedom-degree gyroscope by forming the noncircular holes of the flexible members of an outer tube and an inner tube so that the lengths of first and second flexible parts in the direction perpendicular to the longitudinal direction is shorter than the lengths in the direction which is in parallel with the longitudinal direction. CONSTITUTION:An inner-tube flexible member 1 is inserted into the inside of an outer- tube flexible member 11 in a concentric pattern. The member 1 and the member 11 have the common rotary axial line Z. A flexible part 14 of the member 11 and a flexible part 4 of the member 1 form right angles with the axial line Z. The angles of the members 1 and 11 can be displaced around the axial line passing the intersecting part between the part 14 and the part 4, i.e. the parts can be deflected. The rotors of the parts 14 and 4 can be inclined in the direction perpendicular to the rotary axis, i.e. the parts can be displaced in two axes. In the flexible coupling type supporting apparatus formed in this way, noncircular holes 12 and 13 forming the part 14 have the semi-circular shape. Therefore, the length in the direction of the axial line Z can be shortened by the diameter of one circular hole in comparison with an apparatus wherein the flexible part is formed of the circular hole. Thus the tuning property of a biaxial freedom-degree gyroscope can be improved.

Title: Combustion melting furnace with slag removal device
Inventor: HARADA HIROAKI
IPC: F23J1/02
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To easily remove solidified slag by providing a slag removal device comprising a slag removal head having a shape such that the head can be inserted into a slag discharge port and a drive means. SOLUTION: Exhaust gas near a slag discharge port 5 has a temperature equal to or higher than the melting point of slag. However, water in a water tank 7 has a low temperature of, for example, 60-70 deg.C, and hence the temperature of molten slags 16, 19 reaching the edge 17 of the port 5 falls by radiational cooling and fluidity of the surface of a slag flow decreases so that the slags are solidified. And the solidified slags 18, 18 grow, and hence the port 5 is easily closed. Hence, when solidified slags 18, 18 grow, a cylinder is driven to extend a cylinder axis 13 so that a slag removal head 15 is lowered to insert it into the port 5, whereby the slags 18, 18 solidified on the edge 17 of the port 5 are pushed down by the head 15 and broken or separated from the edge 17 so as to be dropped into the tank 7.

Title: Deterioration judging circuit for laser diode
Inventor: KANEKO SHINJI
IPC: G01M11/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To correctly judge the deterioration condition of a laser diode even when an erase mode is not provided. SOLUTION: This judging circuit judges deterioration of a laser diode when a recording medium for recording data without erase mode is used. A loop band area of an APC loop for controlling photo output of the laser diode is expanded and start up of the laser diode is set at a high speed and respective APC period for erase and write is largely reduced than conventional period. Deterioration condition of the laser diode is decided by using APC period remained by this reduction. As luminous output level exhibits a droop characteristic when the laser diode deteriorates, the luminous output level is detected at termination of APC to decided the deterioration. Whereby, deterioration condition of the laser diode can be decided even if the erase mode is not provided.

Abstract: PURPOSE:To obtain a liquid crystal element indicating a voltage peak value response almost without indicating a response based upon an average voltage by using a specific p-type nematic composition. CONSTITUTION:This liquid crystal element is constituted of the 1st and 2nd bases 1, 2 consisting of transparent glass, rectangular and transparent conductive electrodes 3, 4 consisting of ITO films, orientation films 5, 6, and a liquid crystal layer 7. In this case, the p-type nematic composition capable of obtaining an optical change corresponding to about 40% of an optical change attained when 400 or more AC pulse strings having about 0.1ms width and 20V voltage peak value are impressed at the time of continuously impressing single pulses of having about 0.1ms width and about 20V voltage peak value and respectively charged with positive polarity and negative polarity in a twisted nematic mode is used. Since the peak value of a selected voltage pulse can be distinguished from that of a non-selected voltage pulse even in a state reducing the margin of an average voltage, a sufficiently large optical change difference can be secured between the a selected picture element and a non-selected picture element.
