Title: Fast-forwarding playback device
Inventor: ISHIDA TAKASHI
IPC: G11B27/10
Filed: 1992-08-17
Abstract: PURPOSE:To perform fast-forwarding playback operation by fixed-speed rotation as it is by finding the number of jumped tracks and an increment in playback address after the jump by a controller, and repeating specific operation in order according to the calculated values. CONSTITUTION:Image data are recorded on tracks 1 of a disk 2 in address order while a specific number of sectors is put in one unit, screen by screen. The light from a laser diode 20 is passed through a half-mirror 21 and a lens 3 to form an extremely small spot on the track surfaces and its reflected light is made incident on a 4-split detector 22. Its total amount is sent to the controller 15 through an RF amplifier 5, a demodulating circuit 6, and an address extracting circuit 7. The controller performs specific arithmetic and outputs the result to a data extracting circuit 8 to reproduce data of one screen, then sends its output to a lens driving circuit 11 and a slider motor driving circuit 12 to make a jump, and then repeating the one-screen reproduction thereafter. The magnification of the fast-forwarding playback operation is varied and set corresponding to the number of jumped tracks, so the fast-forwarding playback operation can be performed by the constant rotation at all times without varying the rotating speed of the disk.

Filed: 1989-08-24
Abstract: PURPOSE:To form the title electrode in a simpler way as compared with the conventional way so that the man-hour and material for forming the electrode can be reduced by baking a pastelike activating agent containing a metal after applying the activating agent to the surfaces of parts of a positive temperature coefficient porcelain semiconductor requiring soldering and forming the electrode on the surface where the activating agent is applied and baked by dipping the semiconductor in a plating bath thereafter. CONSTITUTION:After a pastelike activating agent containing a metal is applied to the surfaces of a positive temperature coefficient porcelain semiconductor 1 and the agent is baked, electrodes 2 are formed on the surfaces where the activating agent is baked by dipping the semiconductor 1 in an electroless plating bath. Then the electrodes 2 are baked after the semiconductor 1 is taken out from the plating bath and dried. For example, a pastelike activating agent containing Pd chloride is applied to both surfaces of a positive temperature coefficient porcelain semiconductor 1 made principally of BaTiO3 by screen printing after the surfaces are polished and the agent is baked at 300-750 deg.C. Then Ni-plating is performed on the semiconductor 1 in an Ni-P electroless plating bath and, after the semiconductor 1 is taken out from the bath and dried, the Ni-plated surfaces are baked so as to form the Ni electrodes 2. After the electrodes 2 are formed, cover electrodes 3 are formed on the electrodes 2 by applying Ag paste to the surface of the electrodes 2 and baking the Ag paste at 450-800 deg.C.

At the first, position, image data stored in an image memory 18 are taken into an operating device 19, various treatments are conducted and data of a scattering light on the wafer are extracted. A position of a center of area of every luminous dot of the scattering light is obtained, thereby to calculate and store a reaching position of the wafer 8 after rotated. A luminous dot obtained at the next position is compared with this position. If there is a new luminous dot, a position for the wafer to be shifted is calculated and stored. True above procedure is repeated, for example, up to the 23rd position. When the luminous dots on the wafer 8 are present only at one or two positions, the wafer is judged to have flaws.  If the luminous dots are present, over three or more positions, the wafer is judged to have an adhering substance.

Filed: 1983-11-24
Abstract: PURPOSE:To enable satisfactory discrimination of locations, in which troubles occur, every logical unit by a slight increase in the number of adders by providing a delay latch which stores data transmission to a bus every logical unit. CONSTITUTION:Logical units 1-4 are connected by utilizing a common bus 7, and a common clock cycle begins in a T0 and terminates in T4. When the unit 1 takes into data from the bus 7, the data are checked by a parity checker 10, and from any one of units 2, 3 and 4 the data are transmitted. In accordance with this transmission, any one of delay latch groups 21-22, 31-32 and 41-42 is operated. When errors are detected by the checker 10, the detected errors are reported as a machine check to the unit 5 at timing of the clock cycle T4. The control unit 5 receives a demand at a cycle T2, and stops the clock from a cycle T3 just after the cycle T2. Thus by addition of a delay latch, the location in which troubles occur can be satisfactorily discriminated.
