Title: Detecting system of service interruption for sequencer
Inventor: MITSUO KAZUHIKO
IPC: G05B23/02
Filed: 1983-03-15
Abstract: PURPOSE:To detect easiy the factor for a service interruption when a sequence operation is wrong by storing the information showing the generation of the service interruption in case a service interruption longer than a prescribed period of time of detected. CONSTITUTION:A processing circuit 1 which receives a signal from an input device 5 and delivers the signal to an output device 6 detects the service interruption of a power supply 2. Then the circuit 1 stores the data on the service interruption to a memory 3 backed up by a battery 4 before the voltage drop of the supply 2 exceeds the working limit of the processor 1. A flag showing the service interruption is set up and stored in the memory 3. When the service interruption lasts longer than a prescribed period of time, e.g., 10ms, the operation of the processor 1 is discontinued until the service interruption is over with the service interruption flag set up. When the service interruption is over within a prescribed period, a normal sequence is reset after the service interruption flag on the memory 3 is reset. A display device 7 displays the state of the service interruption flag on the memory 3 and therefore displays the generation of a service interruption longer than a prescribed period of time.

Title: Surface treatment device using magnetic force
Inventor: IIZUKA TOSHIKI
IPC: B24B5/40
Filed: 1994-02-17
Abstract: PURPOSE:To enhance polishing efficiency by providing a surface treatment member with increased pressure through the application of attractive and repulsive forces to the surface treatment member enclosed in a cylindrical body. CONSTITUTION:A magnetic polishing tool 6 having north and south poles on opposite parts of its surface is enclosed in a nonmagnetic pipe and a ring-shaped, annular magnet 2 is disposed around the nonmagnetic pipe. The annular magnet 2 is magnetized so that its overall inner surface 2a serves as the north pole while its overall outer surface serves as the south pole, with part of the inner surface 2a projected inwards to serve as a projected magnetic pole 3. Since magnetic flux concentrates on the projected magnetic pole 3, the south pole of the magnetic polishing tool 6 is attracted thereto and an end face 6a comes into contact with the inner surface 5a of the nonmagnetic pipe. Also, the north pole of the magnetic polishing tool 6 is exerted with a repulsive force by the north pole formed on the inner surface 2a surrounding the north pole, so the pressure that the magnetic polishing tool 6 applies to the inner surface 5a increases and the position of the magnetic polishing tool 6 is kept stable.

Abstract: PURPOSE:To obtain high picture quality effect by controlling the saturation of a photoelectric converting element so as not to cause the saturation of a horizontal scanning charge carrier element in a CPD image pickup device thereby suppressing completely blooming caused by a difference of saturated electric charge amount between the photoelectric converting element and the horizontal scanning charge carrier element. CONSTITUTION:A level shift circuit 13 boosts a low level of a vertical gate pulse VG outputted from a drive circuit 9 by DELTAV into VG'. The VG' pulse becomes a vertical gate pulse VGn' of the n-th line via an MOS switch for vertical selection selected by a vertical scanning circuit. A saturated electric charge Q1 of a photodiode by an example of this execution and a saturated electric charge Q1+ Q3 (Q3=Q2) of the photodiode in a conventional example depend on the DELTAV. Only the Q1 of this example of execution is transferred at t0-t11, and the Q1+ Q2 are transferred in the conventional example to a Cc. The DELTAV is selected optionally and no blooming is caused n this execution example where the saturated charge of the photodiode is selected in advance to the value Q1 less than the saturated charge of one stage of the horizontal scanning charge transfer element.
