Title: Control circuit for disk motor
Inventor: ISHIGAKI YUZO
IPC: G11B19/28
Filed: 1986-02-07
Abstract: PURPOSE:To prevent a disk motor from being over-drive toward an abnormal high speed without any special sensor by inserting a limiter means selectively turned on/off in response to a signal detection state from a disk to an output path of an accelerating direction control pulse for a disk servo. CONSTITUTION:A DM+ supply line 24 outputted from a servo control circuit 18 is connected to ground via a Zener diode ZD and a transistor (TR) operated as a limiter.

Title: D channel spare switching system in isdn basic user network interface
Inventor: NISHIOKA JUNJI
IPC: H04Q5/00
Filed: 1990-02-05
Abstract: PURPOSE:To switch communication to a spare channel circuit connection part without interrupting the processing of a D channel by delivering always the transmission reception data of the D channel to a B1 or a B2 channel circuit connection part which is not transferring data as well, and switching the communication to the B1 or the B2 channel circuit connection part when a hardware error is detected in said D channel. CONSTITUTION:When the B1 channel circuit connection part 30 receives a 'B1-RSV' signal (1), it folds quadruply D channel data sent through an OR gate 503, and changes it into 64Kbps data, and sends it to a switching circuit B 51. When the hardware error arises in the D channel circuit connection part 2 while a B1 channel is in 'idle' state, and a '+D HERR' signal (2) is detected, a communication control part 4 blocks the signal '-B1-ACT' showing that the B1 channel is 'idle'. Accordingly, in the above-mentioned AND gate 501, the OR gate 502 is energized while the signal '+B1-RSV' (1) is not interrupted, and simultaneously, when the AND gate 510 in the switching circuit B 51 is opened by said '+D-HERR' signal (2), the switching of the D channel to the B1 channel is completed.

IPC: G06F1/04
Filed: 1984-02-14
Abstract: PURPOSE:To reduce power consumption at holding state by delaying an operating speed slower than normal state when minimum necessary operation is to be executed at the holding state. CONSTITUTION:A microcomputer outputs a signal having prescribed frequency from its oscillation circuit 1 and divides its frequency by a frequency dividing circuit 3. Both outputs CLK1, CLK2 from the circuits 1, 2 are impressed to a switching circuit 3, which is controlled by a control signal CHG from an operation control circuit 5 to output any one output selectively to a clock generator 4. The generator 4 forms a clock signal CP on the basis of the selected signal CLK and outputs the clock signal CP to respective internal circuits. When holding state is detected 6 at a time of power failure, a switching circuit 3 selects the frequency-divided output CLK2, so that the operating speed of the microcomputer is delayed by the frequency divided by the frequency dividing circuit 2.
