Title: Semiconductor integrated circuit
Inventor: KOBAYASHI OSAMU
IPC: G06F1/04
Filed: 1988-06-14
Abstract: PURPOSE:To prevent the abnormal operation of an internal circuit due to heating by forcibly transiting the voltage level of a clock pulse, which is supplied to the internal circuit, to one level to be determined in advance when the stop of the clock pulse is detected with a clock stop detecting circuit. CONSTITUTION:When a clock pulse S1 goes to be a high level for >= a constant time T1 by disconnection, etc., a clock operating signal S2 goes to be a low level and an AND gate 30A is closed. Accordingly, a clock pulse S3 is forcibly transited to the low level. Reversely, when the S1 is stopped in the condition of the low level, the S3 is also at low level. Accordingly, in the clock stop condition, the clock pulse S3 certainly goes to low level. Analog switches 13a, 17a and 17b go to an opening condition and an analog switch 13b goes to a closing condition. Thus, the consuming current of a chopper type comparator 11 becomes extremely small and the consuming current of a parallel comparison type A/D converting part 10A goes to be <= the average current of an operating time.

Title: Controlling system for start of write/read action
Inventor: YOSHIDA TADASHI
IPC: G11B20/10
Filed: 1989-06-09
Abstract: PURPOSE:To shorten an access time by detecting a sector prior to a sector being the object of a read/write action by one, previously discriminating one having the possibility of a comparison error by means of a timer value and giving the instruction of the start of the read/write action to a format control part. CONSTITUTION:When a sector detection means 12 detects that a head reaches a position prior to the sector being the object of the write/read action by one when it comes to a state where the write/read action can be started, the sector detection means 12 starts a timer. A control means 13 giving the instruction of the start of the write/read action moves to an interruption processing based on an interruption signal from the sector detection means 12 and gives the instruction of the start of the write/read action to a format control means 11 based on the output of a discrimination means 14. When the timer does not reach a prescribed value, the control means 13 gives the instruction of the start of the write/read action to the format control means 11 by taking it to be no possibility of the comparison error. Consequently, one rotation- waiting is avoided. Thus, the access time can be shortened.
