Title: Image forming device provided with self-repairing function
Inventor: SHIMOMURA YOSHIKI
IPC: G06F9/44
Filed: 1992-10-12
Abstract: PURPOSE:To make the scale of a fault diagnostic system small and to shorten the time required for repairing a fault in order to make a self-repairing system into a practical machine incorporateding type system. CONSTITUTION:A virtual case holding part 12 is installed in a machine incorporated software part, and a virtual case is previously generated to be stored by a virtual case compiler 16 on the outside of the device. The diagnosis of the fault is performed by comparing a value obtained by making each sensor value a fuzzy qualitative value basing on a fuzzy membership function with the virtual case. When the sensor value exists in a previously set neutral space where grade takes an intermediate value in the case of making each sensor value the fuzzy qualitative value basing on the fuzzy membership function, an actuator is operated so that the sensor value is out of the neutral space. Thus, each sensor value becomes the fuzzy qualitative value which is easily dealt with in the following diagnosis of the fault, and erroneous diagnosis is prevented and diagnostic processing is quickened.

IPC: H05B3/00
Filed: 1989-10-20
Abstract: PURPOSE:To eliminate variance in temperature set value among devices by storing the temperature set value of fixation temperature in a storage means, connecting a calibrating means only when the temperature set value is calibrated, and rewriting the temperature set value in the storage means according to a temperature calibration reference value outputted by the calibrating means. CONSTITUTION:The temperature set value of fixation temperature is stored in the storage means 9 and when this temperature set value is calibrated, the calibrating means 16 equipped with an external variable resistance 15 is connected to terminals 12- 14. A mode changeover switch 10 is switched to a calibration mode and the power source of a temperature control part is turned on. Then the temperature calibration reference value which is set by the variable resistance 15 of the calibrating means 16 is displayed on a display means 8 by a CPU 5, so the variable resistance 15 is varied over a look at the displayed temperature calibration reference value, which is adjusted to specific set temperature. Then the adjusted temperature calibration reference value is sent to the storage means 9 from the CPU 5 and the stored temperature set value is rewritten with the temperature calibration reference value. Consequently, the fixation temperature is prevented from varying.

Title: Multi-level sheet feeder
Inventor: MORIYA SHIGERU
IPC: B65H9/14
Filed: 1985-12-07
Abstract: PURPOSE:To shorten the time for partial copying when a multi-level sheet feeder is used, by furnishing a speed control means which puts the transport speed into No.1 speed, High, when a copy request signal for the first sheet is given to a microprocessor, and into No.2 speed when attainment of the specified position is sensed. CONSTITUTION:When the leading edge of a copying sheet is sensed by a sensor S4a, a detection signal is given to a CPU, which turns the sheet feed pulses into H, and this is informed to the body of copying machine. Therefrom pulses of a sensor S9 of motor M1 are calculated, and the time when the motor M1 has rotated for the angle corresponding to the leading edge reaching a transport roller 20a, is sensed to lead to turning-off of a feed solenoid SLa. The sheet passes a jam sensor S6 and is fed into the copying machine by transport rollers 23, 24 at the sheet feed port on the body side. Here the CPU performs speed control so that only the first No.1 copy will be at High speed transported from a sheet feed tray of a sheet feed device till transport rollers 23, 24 in the body of copying machine. This should shorten the copying time greatly in minor quantity case, for ex. only a single copy shall be made.

Title: Counting device
Inventor: YAMAMOTO HIROYUKI
IPC: H03K21/02
Filed: 1988-10-31
Abstract: PURPOSE:To realize the mutual sharing between an input signal line and reset signal line by outputting a reset signal of the small pulse length when a small numeric value counting counter counts the preset value set previously and the outputting a reset signal of the large pulse length when a large numeric value counting counter counts the total preset value. CONSTITUTION:When a counting action is started, the presence or absence of the input decided for a reset signal. When the input of the reset signal is confirmed, the counted value is increased by +1. Then a reset signal 1ms of the preset counted value is outputted when the counted value of a small numeric value counting counter reaches 5. Thus the counting and resetting actions are repeated again for the preset value. While an all-reset signal 20ms of the total preset value is outputted when the counted value of a large numeric value reaches 100. In such a manner, both reset signals can be confirmed by the difference of pulse length between them. Then the signal lines can be shared each other between the input signal and the reset signal and therefore a counting device can be miniaturized.

Title: Piezoelectric resistance sensor device

IPC: G01D5/16
Filed: 1994-10-04
Abstract: PURPOSE: To permit operating mechanical stress to change the current distribution of an electrode and easily measure electric signals in the form of difference current, by making electrodes, which are mutually connected by a suitably shaped doped resistance layer so as to extract both currents, to have equivalent potentials. CONSTITUTION: Three or four electrodes 1-3 and one resistance layer 5, which specially has a shape matching with the electrode shape, are included. A fixed current is supplied to the resistance layer 5 through the electrode 1 and is distributed uniformly to both the electrodes 2 and 3. Thus, it is closed and a low resistance piezoelectric resistance sensor which is not affected by disturbance is obtained. The sensor has a merit in measuring not a voltage but a current and a merit of high efficiency by symmetrical potential distribution. These characteristics are suitable for manufacturing pressure/acceleration sensors from semiconductor material.
