  • Patent number: 6285164
    Abstract: An apparatus for detecting an integrated value of current flow. The apparatus includes an integrator having an integration capacitor, to which a current sensor voltage is inputted, for outputting an output voltage corresponding to an integrated value of the current sensor voltage, and a resetting circuit for clearing integration electric charges accumulated in the integration capacitor to reset the integrator when the output voltage has reached an upper threshold value or a lower threshold value. The apparatus also includes a counter for counting the number of resets of the integrator in an upper direction or in a lower direction, and a connection-polarity inverting circuit for inverting a polarity of inputting of the current sensor voltage to the integrator, a polarity of connecting of the integration capacitor to the integrator and a counting direction of the counter, alternatively, at a regular time interval and synchronously.

  • Patent number: 5982719
    Abstract: The speed of a disc handling operation by a disc apparatus having disc changer capability is significantly increased and, at the same time, the disc handling operation is performed with stability. In the disc apparatus according to this invention, a plurality of reproducing units loaded with discs are moved independently and disc reproduction is started by returning the reproducing units to their dedicated positions. Simultaneous returning of the plurality of reproducing units is prevented and each reproducing unit moves for refuge while reproducing the disc. This novel setup significantly shortens the time for moving the reproducing units for disc reproduction. When continuously reproducing a plurality of discs accommodated in proximity, the plurality of reproducing units are moved in a stacked state rather than independently. This also contributes to a significant reduction of the time in the disc handling operation.

  • Patent number: 5875156
    Abstract: A CD-ROM is provided with an area for forming a character/graphic pattern. The character/graphic pattern is formed in such a way that data, which generate on the CD-ROM two sorts of pit patterns having average reflectances different from each other to a perceptible extent, are respectively recorded inside and outside the character/graphic pattern. Unless an illegal copy disc is produced by duplicating the legal original disc of the CD-ROM at a very high precision, the character/graphic pattern of the copy disc is invisibly deformed by the discrepancy between the arrangements of the pit patterns of the copy disc and the original disc.

  • Patent number: 5751671
    Abstract: A character and/or graphics pattern area for recording specific data is provided on a CD-ROM. When an original disk is prepared, a specific pit pattern corresponding to the specific data is recorded at a first predetermined tracking linear velocity controlled by a specific tracking linear velocity control system for each track so that a character and/or graphics pattern cannot be identified. When a copy disk is produced from the original disk, if data is recorded at a second tracking linear velocity controlled by a specific tracking linear velocity control system, the character and/or graphics pattern of visible size appears on the copy disk because of an optical reflection factor difference between areas caused by placement of the specific pit pattern corresponding to the specific data.

  • Patent number: 5726702
    Abstract: A television signal receiving apparatus which can read program information relevant to a television program from an optical disk medium, interlocked with the television program and can reproduce and display the read program information. Program information (broadcasting information including program names, broadcasting channel names and broadcasting dates and times and appendant information relevant to the contents of the programs) relevant to the television programs to be displayed by the television receiver/display is recorded in the optical disk medium. When a user instructs a display of the program information by the selection and decision input unit, the television control unit transmits the display request and time information from the clock apparatus to the control unit of the optical disk unit. The control unit makes the appendant information to be reproduced from the optical disk medium, by using the broadcasting channel name and the time information as retrieval information.
