Abstract: PURPOSE:To eliminate the need to prepare pallet data, frame by frame, when the full-color moving picture image is reduced in color number and displayed. CONSTITUTION:The full-color image which is transferred continuously from a host device and compressed, frame by frame, on a DCT basis is expanded into the original full-color image by expansion logic 1 and temporarily stored in one of frame memories 4-1-4-3 in a buffer memory 4. Further, the DC component of a DCT block is inputted from the expansion logic 1 to a scene change detector 2 and a change point of a scene is detected from successive frames according to the change of the DC component; and pallet data for color number reducing display are generated from the full-color image of the frame at the time of the detection and set in an LUT 6, so that the full-color image in the scene change generation frame and respective following frames of the same scene stored in the buffer memory 4 is converted into a color image reduced in color number during the generation.

Title: Rotation detector
Inventor: KATAGIRI TOSHIYUKI
IPC: G01P13/04
Filed: 1986-03-31
Abstract: PURPOSE:To always detect a reversion in rotation quickly without variations, by performing a discrimination based on a time sequence relationship of edge pulses of a rotary pulse different in the phase with a pair of rotation sensors. CONSTITUTION:When a capstan motor of a rotor rotates forward, a phase difference of 90 deg. exists between output pulses of rotation sensors 3 and 4 and a pulse equivalent to the phase difference of 90 deg. is applied to a clock terminal CLK of a D type FF 17 through an AND gate 14 to which an edge pulse is applied from exclusive OR circuits 12 and 13. Then, an output of OR gates 15 and 16 to which are separately applied a Q output of the FF and an output of the circuit 12 and a Q output thereof and an output of the circuit 13 go to H while an output of an AND gate 18 goes to H and hence, there is no L output indicating a reversion in rotation. On the other hand, with the occurrence of a reversion, an output pulse of the sensor 3 breads off and output pulses of the sensor 4 are detected twice continuously. Likewise, the output of the gate 18 moves to L immediately after a reversion in rotation. Thus, the reversion in rotation can be always detected quickly without variations.

Abstract: PURPOSE:To arrange a disk plate as many as possible in a device by setting a distance between the disk plates less than double the thickness of a magnetic head supporting device by shifting adjacent suspensions in a transversal direction, and arranging the side planes of a beam part oppositely to each other. CONSTITUTION:Magnetic heads 4 and 4' are shifted by double to five times the plate thickness of the suspensions 9 and 9' in the transversal direction of the suspensions 9 and 9', and the suspensions 9 and 9' are arranged in back to back.
