Title: Runaway detecting device for phase locked loop
Inventor: YAMAGUCHI YOSHIAKI
IPC: G11B20/14
Filed: 1989-04-20
Abstract: PURPOSE:To stop a runaway and to try rereading operation corresponding to the cause of a failure in reproduction by recognizing a saturation state where in a VCO control voltage is saturated at a voltage determined by its loop system and detecting the runaway state of the phase locked loop (PLL). CONSTITUTION:A comparing circuit 1 compares data pulses DP read out of a recording medium with the oscillation clock VC outputted by a voltage- controlled oscillator 3 as to their frequencies or phases and the comparison error signal CE outputted by the comparing circuit 1 is converted by a low-pass filter 2 into a constant voltage-controlled oscillator control voltage (VCO control voltage). The VCO control voltage VV is sent to the runaway detecting circuit consisting of a voltage comparing circuit 4 and a timer check circuit 5 to count a timer clock when the VCO control voltage VV exceeds a reference voltage and outputs a runaway detection signal RD when the counted value exceeds a specific value. Consequently, the runaway of the PLL is stopped and the rereading operation for recording information corresponding to the cause of the failure in reproduction can be tried.

Title: Specimen rear gass pressure controller
Inventor: TSUBONE TSUNEHIKO
IPC: H01L21/3065
Filed: 1988-04-27
Abstract: PURPOSE:To improve reproducibility of plasuma treatment by predicting and determine, by rise time between pressure switches, a gas flow rate when gas pressure at the specimen rear becomes the specified pressure. CONSTITUTION:At the same time when treatment gas is introduced into a treatment room 3, a valve 17 and an exhaust valve 27 are opened and as gas, He gas is stabilized at, e.g., initial flow rate Q0=6SCCM by a mass flow controller 16, and then the exhaust valve 27 is closed so as to raise the back pressure of a wafer 8. That pressure rise state is measured with a Pirani gage 19 in a pipe 18 and the time lapse between the low pressure side contact and the high pressure side contact of a meter relay taken in a microcomputer 22 is measured, and arriving pressure is predicted as Pe=Q0/Se=3.8Torr. In case that gas set pressure at the back is determined as P set=3.3Torr, since there is difference in the arriving pressure, Q0 is compensated and if the compensation value is defined as Q1, by the approximation method of Newton by differenciation, it comes to be Q1=Q0+Pset/Pe=5.2SCCM, and the action is executed again with Q1 as a new Q0 so as to determine gas flow rate.

Title: Control system for terminal device
Inventor: OKUNO YASUO
IPC: H04Q9/00
Filed: 1987-04-25
Abstract: PURPOSE:To simplify circuit constitution and to shorten an operation time by allowing a terminal device to switch its current operation state when the continuance of a signal from a main device exceeds predetermined continuance. CONSTITUTION:The main device 2 outputs the control signal which continues over a predetermined time to the terminal device 1. A timer means provided to each terminal device 1 measures the continuance of the signal. When the measurement result exceeds the predetermined continuance, the terminal device 1 switches its current operation state. Namely, the main device 2 needs not to sends an instruction based upon a specific grammatical rule when switching the operation state of the terminal deice 1, which needs not to decode the contents of the control signal from the main device 2 for switching the operation state of the terminal device 1 either. Consequently, the circuit constitution is made extremely simple and the operation time is greatly shortened.
