IPC: G11B20/14
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To supply stable audio sampling clocks in both locked and unlocked modes by an identical circuit structure. SOLUTION: An AFSIZE data and a reference frame signal are supplied to an arithmetic operation circuit 23. The circuit 23 is operated by an operation clock much faster than an audio sampling clock. In the circuit 23, an average value among AFSAIZE data equivalent to five frames is obtained. A frame signal generated by counting up to the average value based on the operation clock is phase-compared with the reference frame signal by a phase comparator 24, an obtained phase difference is looped through an LPF(low-pass filter) 25 and a VCO(voltage control oscillator) 26 or the like to the phase comparator 24 and thus a PLL(phase locked group) is constituted. The output of the VCO 26 is supplied to a 1/n frequency divider 28, and led to a terminal 29 after being set as an audio sampling clock. Since the average value of the AFSIZE data is used, a sampling clock is stabilized.

Abstract: PURPOSE:To accurately determine the end of an etching process by a method wherein a heating means is provided on the wall of a reaction container. CONSTITUTION:A heating wire 7 is provided on the outer wall of a chamber 1 opposite to a termination detecting sensor 5 so that the emission spectrum of plasma generated in the chamber 1 may reach the termination detecting sensor 5 without being shielded by the heating wire 7.

Title: Controller
Inventor: GOTO MAKOTO
IPC: H02P29/00
Filed: 1987-10-08
Abstract: PURPOSE:To achieve a good control performance in short time even when a setting is modified, by providing a means for properly stopping update operation of an update/storage means. CONSTITUTION:A speed detector 3 outputs a synchronous signal (q) and a speed signal (b) based on a signal fed from a rotation sensor 2. Upon provision of the synchronous signal (q), an operating unit 5 takes in the speed signal (b) and operates a speed error between a reference signal and the speed signal. Then the speed error and a value stored in an update/storage means is synthesized to produce a control signal (y). Upon finish of speed error operation by predetermined times, values stored in the update/storage means are updates and stored. When setting values are modified in step, update/storage operation is not carried out. Upon elapse of a predetermined time, update/storage operation is started. Consequently, spike speed variation immediately after modification of setting values is converged quickly.
