Title: Plasma processor
Inventor: AKIBA MASAKUNI
IPC: H05H1/46
Filed: 1977-10-24
Abstract: PURPOSE: To realize the increase of the process number as well as the uniform processing by carrying out the gas plasma process with shift of the electrode.  
     CONSTITUTION: Electrode 6 and 7 used for the gas plasma production are shifted via rotations of screw 9 and through control driving 11 of motor 10. The electrode has increased process quantity near position A, and the plasma intensity is lessened gradially at position B. Thus, the plasma is extenguished in the course, and the gas density is lowered with the reduced process quantity. In this connection, the electrode shift speed is increased near A and then decreased as going further away from A, so a large amount of the test sample can be processed uniformly with one plasma process operation

Title: Prevention system against malfunction of detecting circuit for processor malfunction
Inventor: MORIYAMA YUTAKA
IPC: G06F11/00
Filed: 1983-07-13
Abstract: PURPOSE:To prevent malfunction even in case of wrong access to an undefined address and to continue normal data processing by stopping the output operation of an abnormality detecting circuit when the monitor function of a processor is operated externally. CONSTITUTION:While a data processor is in operation, ''0'' is set in a register 5 and an AND circuit 4 is on; when a processor 2 accesses an undefined address, abnormality is detected 3 and the AND circuit 4 outputs abnormality to stop the processor 2. Now, when a monitor command is inputted on a keyboard 1 so as to monitor the operation state of the processor through external operation, the processor 2 sends 1 to the register 5 to turn off the AND circuit 4. Even if access to the undefined address is attained by mistake in said state and abnormality is detected 3, the abnormality signal is cut off by the AND circuit 4. When a monitor program ends, the register 5 is reset. Consequently, malfunction in monitoring operation is prevented.

Filed: 1979-10-03
Abstract: PURPOSE: To facilitate battery drive by reducing electric power consumption by providing a means of cutting off electric power supply to each part except an arithmetic processing part when a metered-value-zero state continues for a prescribed time.  
     CONSTITUTION: When object to be method 1 on saucer 2 is removed, there are no weight data of counter 5 and arithmetic processing part 6. As timer part 12 stays in a timer-set state continuously for a prescribed time, timer part 12 is placed in a time-up state with the zero detection output of metered-value-zero decision part 11 that has decided the weight data. Then, arithmetic processing part 6 having received the time-up output releases switch driving circuit 9 from an activated state to open switches 13 and 15, so that electric power supply to photoelectric conversion part 4, counter 5 and display part 7 will be stopped. If metering operation is started before the time is up, timer part 12 is immediately reset to put the electric power source to work. Thus, a waste of electric power is prevented and battery drive can be facilitated.
