Title: Image forming device
Inventor: KURATO SHIGEO
IPC: G03G21/00
Filed: 1988-05-23
Abstract: PURPOSE:To always stabilize the electrified potential of a photosensitive body at a desired one by controlling an electrifier based on the measured value of a potential sensor whose output is calibrated so that the surface potential of the photosensitive body can be electrified to a fixed potential. CONSTITUTION:Whenever the main switch of the image forming device, for instance, is turned on, a 1st switching means 37 is switched. In response to that switching, the photosensitive body 21 is biased to a predetermined high voltage, and the measured value of the potential sensor at that time is read out. An electrifier control means 35 controls an output from the electrifier 23 to electrify the surface of the photosensitive body, and at the same time the output of the electrifier 24 is adjusted so that the output from the potential sensor 24 can be equal to the read-out measured value. In such a way, the title device is provided with the potential sensor 24 detecting the surface potential of the photosensitive body, and a circuit automatically calibrating the output of the potential sensor at a fixed timing, whereby the output from the potential sensor measuring the surface potential of the photosensitive body can be one which is always calibrated. Thus, the photosensitive body can be electrified at a desired potential.

Title: Failure countermeasure system for button telephone set
Inventor: SUGIURA RIYUUZOU
IPC: H04M1/71
Filed: 1981-08-12
Abstract: PURPOSE:To normally keep operation between a master device and other slave devices, by detecting a failure of transmission/reception function of a slave device of by the master device itself, and disconnecting a transmitter/receiver from a control line. CONSTITUTION:A control signal TxD from a master device is transmitted to a slave device designated with polling via a transmission section as a pulse signal. During the transmission, a reception section is stopped for the reception  with an inhibition signal RTS but can receive a signal from the slave device  with a photocoupler PC1 through the inversion of the signal RTS. The transmission/ reception circuit of the slave device makes signal transmission/reception to/ from the master device with photocouplers PC13 and PC14. A slave processor  monitors an output signal IRQ of a photocoupler PC12 for transmission monitor  and if a failure is detected in the said signal, it is discriminated as the failure  of transmission/reception function. A signal EM is inverted and a transistor Q11  is turned off via the photocoupler PC11 to disconnect the transmission reception circuit from the control line.

Title: Scanner
Inventor: KUNISHIMA TOSHIAKI
IPC: H04N1/12
Filed: 1983-07-12
Abstract: PURPOSE:To perform the scan with high stopping accuracy by using a means which decides the number of driving steps of a step motor in response to the number of hitherto driving steps of the motor serving as a motive power supply of a scanner. CONSTITUTION:When an original is set, both switches 37 and 38 are operated. The size of the original is informed to a controller 11. A transmission line is set up to the remote side. When a start switch on a control panel 10 is operated, the signals are transferred with a receiver of the remote side to decide a transmission mode. A flag which decides the amount of steps is set at a low level at first and then switched in a fine reduction mode in response to the output of a counter which divides the paper feed signal of a step motor 7 into two parts. In this case, the number of driving steps of the motor 7 is decided in response to the number of hitherto driving steps of the motor 7. Thus the motor 7 is revolved by an amount equivalent to two or three steps of a 1.2 phase energizing sysem every time the paper feed is carried out by an amount equivalent to two lines.

Title: Error display method for programmable controller
Inventor: TSUKADA SADAYUKI
IPC: G05B19/048
Filed: 1988-05-24
Abstract: PURPOSE:To avoid such an inconvenient case where all error contents are overlooked by performing the switching actions for each set-up state of a timer part which is set up for each prescribed time set with detection of the first error and displaying errors in turn and repetitively in the order of higher priority ranks. CONSTITUTION:The contents of occurred errors are stored successively into an error store table 3b in the order of higher priority ranks for display of errors that is previously decided for each of error contents regardless of the order of occurrence of errors. While a timer part is set with detection of the first error and said contents of error stored in the table 3b are displayed at a display part 4. Hereafter these error contents displayed at the part 4 are switched for each set-up of the timer part and in the order of higher priority ranks for display of errors. When the display is through with the error contents of the lowest priority rank, the error contents of the highest priority rank are displayed again. Thus it is possible to omit the troublesome operation of a reset switch 5 and also to prevent the overlooking of the occurred errors.
