Title: Transfer and fixation device of electrophotographic device
Inventor: NAKAYAMA SHIGERU
IPC: G03G15/16
Filed: 1982-09-22
Abstract: PURPOSE:To prevent transfer shifting or drum damage even in case of the displacement of a transfer roll, by positioning the center point of a photosensitive drum not on the center line between a transfer and a transfer and fixation roll. CONSTITUTION:Even when a sheet 28 inserted into between the transfer roll 24 and transfer and fixation roll 26 is thick, the roll 24 is displaced as shown by a dotted line, but the prolongation of the straight line connecting the center points of both rolls 24 and 26 together does not run the center point of the photosensitive drum so that the extent of the displacement of the roll 24 to the photosensitive drum 20 is less than that of upward displacement. Consequently, when the thick sheet is inserted, or even when the roll 24 is displaced owing to oscillation due to the driving of a main frame, the gap between the drum 20 and roll 24 does not vary greatly; transfer shifting which used to occur is prevented and even in conveyance and installation, damage to the drum 1 due to the contacting of the roll originating from a shock is eliminated.

Abstract: PURPOSE:To judge the active state of an oxygen concentration sensor accurately, by detecting the fact that the voltages between the electrodes of a battery element and an oxygen pump element are the voltages within the specified ranges after supply of a pump current to the oxygen pump element is started. CONSTITUTION:A detecting part 1 of an oxygen concentration sensor, which is arranged in the exhaust system of an internal combustion engine 2, is composed of an oxygen-ion conductive solid-state electrolyte material 12 and pairs of electrodes 16a, 16b, 17a and 17b, which hold the material. The solid-state electrolyte material 12 and the pair of the electrodes 16a and 16b act as an oxygen pump element 18. The solid-state electrolyte material 12 and the pair of the electrodes 17a and 17b act as a battery element 19. A heater element 20, which heats the elements 18 and 19, is provided on the outer wall surface of an atmosphere reference chamber 15. Supply of a pump current to the element is started based on the control of a control part 4. When the voltage between the electrodes of the element is the voltage within a first specified range and the voltage between the electrodes between the electrodes of the element 18 is the voltage within a second specified range, it is assumed that the temperature of each element has reached a temperature, where the desired proportional output characteristic is obtained. Thus the active state of the oxygen concentration sensor is judged.

Title: Logic circuit
Inventor: SHIBATA TOORU
IPC: H03K19/003
Filed: 1983-09-07
Abstract: PURPOSE:To erase unnecessary pulses by connecting drains and sources of the first and second transistors TRs to each other and applying a complementary signal of an input signal and a delay signal to the gate of each TR. CONSTITUTION:Drains of TRs 41 and 42 are connected to lead out an input terminal, and sources of TRs 41 and 42 are connected to lead out an output terminal. The input signal is applied to the gate of the TR41 through an inverter 43, and the input signal is applied to the gate of the TR42 through inverters 44 and 45. The delay time due to inverters 44 and 45 is longer than that due to the inverter 43, and this difference is made equal to the width of input pulses. If a pulse which is switched from the low level to the high level is applied to the input terminal, the high level of the input signal is not transmitted because TRs 41 and 42 are cut off together during the period of the high level of the input signal, and the output signal is always in the low level.
