Filed: 1993-03-19
Abstract: PURPOSE:To prevent the occurrence of a medium breaking down by detecting the load condition of a spindle motor, stopping the motor when the condition exceeds an optimum range and detecting a chucking miss of a recording medium. CONSTITUTION:After a spindle start signal SS is outputted, a wind signal WS is risen to a logic H level at a certain time. By this timing, the driving of a spindle motor is stabilized. Thus, when the value of a driving current detection signal VV exceeds the range of prescribed reference voltages VF1 to VF2, that are set by voltage dividing a power supply voltage Vcc through voltage dividing resistors R1, R2 and R3, a comparator 14 makes a chucking miss signal SE to a logic H level. A control means commands a driving logic circuit 8 to stop the motor, driving signals DV1, DV2 and DV3 are stopped and the motor stops. The control means confirms the motor stop, operates the eject mechanism of a magneto-optical disk and the magneto-optical disk, which is miss-chucked, is ejected.

Title: Ceramic multilayer circuit board
Inventor: YOKOGAWA SAKAE
IPC: H05K3/46
Filed: 1990-03-30
Abstract: PURPOSE:To reduce a resistance in a through hole as compared with the case having a transfer pattern by forming through holes having arbitrary angle on the surface if conductor patterns of positions deviated at upper and lower surfaces of a board are connected via the holes, and eliminating the transfer pattern. CONSTITUTION:Sheets formed with wiring patterns 5 are so laminated by using a laminating jig as not to be deviated, and integrally formed by a hot press method to form a laminate 7. Pin hitting preliminary holes 8 are opened at predetermined positions to be formed with the holes, and conductor pins 9 are hit. Eventually, the laminate 7 is baked to remove its binder each time of the hit pin 9 to obtain a based body 10. Thus, when the inclined hole to the surface is formed at a ceramic board by hitting the pin 9, not only an increase in resistance due to the transfer pattern but also an increase in resistance due to laminating deviation caused when the hole is opened at each one sheet to form the through hole can be prevented, the resistance value of the formed through hole is the resistance itself of the hitting pin, thereby reducing the resistance value.
