Title: Electrophotographic copying machine with surface potential sensor
Inventor: YAJIMA MASAMI
IPC: G03G15/00
Filed: 1985-12-17
Abstract: PURPOSE:To prevent the generation of a sensing failure, by constituting the titled copying machine so that a surface potential sensor can be started again, when the surface potential sensor is in an abnormal operating state. CONSTITUTION:When the oscillation frequency of an oscillator 1a is within a correct range, an oscillation output passes through a BPF 2 and is detected 3, smoothed by an integrator 4, and thereafter, compared with a prescribed value in a comparator 5, and the output of the comparator 5 is supplied to a CPU 7. When the oscillator 1a does not execute an oscillation by a normal frequency, namely, when it is out of the correct range, the oscillation output does not pass through the BPF 2, therefore, the output of the comparator 5 is not generated. Accordingly, whether the output of the comparator 5 is high or low, and exists or not is discriminated by the CPU 7, and whether the oscillation frequency of the oscillating part 1a is normal or not is detected. In this state, in accordance with the output of the comparator 5, the output of the CPU 7 is supplied to the oscillating part 1a, the oscillation of the oscillating part 1a is stopped temporarily, and thereafter, it is restarted. By this restart, the condition of the time for starting the oscillation is changed, therefore, there is the possibility that the oscillation frequency becomes normal. Also, even if the restart is executed by the prescribed number of times, when a normal frequency is not obtained, the restart is stopped, and the sending of the potential is not executed.

Filed: 1992-09-30
Abstract: PURPOSE:To reduce the error detection operating time and to accelerate the signal processing speed by inhibiting and eliminating a detection operation at a redundant signal section when error location detection operation is finished and implementing the detection operation only by an information signal part. CONSTITUTION:When a chain search circuit (error location detection means) 31 completes the detection of a signal of an information signal section (DATA), the section 31 makes detection as to a signal of a redundant signal section (ECC) succeedingly.

Filed: 1992-10-23
Abstract: PURPOSE:To apply a remote monitoring device to plural controllers without changing the basic program by providing a storage means storing both of the address table of the designation of transfer destinations and recent state tables. CONSTITUTION:At first, for some state within state data transmitted from a controller 6, the location of the address where some state is stored is searched by the state location address within the transfer destination designation data table in a data ROM part 4.

Next, after one piece of state data is transferred, the decision of the next state is performed. Thus, a remote monitoring controller 1, that is, a microprocessor 2 decides the state change after the latest states of all the controllers 6 are transferred to the latest data table.

Abstract: PURPOSE: To provide a comparatively inexpensive and lightweight convergent module for a divergent light source by providing the module with a 1st aperture for restricting a circular part for receiving a laser diode assembly and a 2nd aperture end for restricting a 2nd circular part having diameter smaller than that of the 1st circular part.

The flange 41 has a diameter larger than that of the 2nd circular part 31 and the holder 40 is prevented from being rotated around the center axis of the holder 30 due to the existence of a notch 49 in the flange 41 of the holder 40 which is cooperated with a groove 32 formed in the 1st circular part 35. Consequently an highly accurate focusing or convergent module having inexpensive structure can be obtained.

Title: Perfusion apparatus
Inventor: UMEYAMA KOICHI
IPC: A01N1/02
Filed: 1989-11-04
Abstract: PURPOSE:To obtain a perfusion apparatus having excellent operability by measuring a flow pressure corresponding to the flow resistance between the organ-connecting position and the position of a pressure sensor, subtracting the flow pressure from the flow pressure detected by the pressure sensor and determining the flow pressure of perfusate to be supplied to the organ. CONSTITUTION:For example in a motor-controlling circuit to be built in an electrical equipment part of an organ-preservation apparatus, the initial setting of data relating to the flow pressure characteristics of a perfusion circuit and to be stored in a memory part 3 is carried out by continuously increasing the rotational speed of a motor from zero by a motor-speed controlling part 4 of a manual mode in a state free from the organ connected to a perfusation circuit. During the above process, the rotational speed R of the motor is inputted to a CPU 1 by a detection part 7 and, at the same time, the flow pressure of the perfusate is inputted to the CPU 1 by the pressure sensor of a pressure detection part 2. A pressure PC(R) corresponding to the flow resistance between the organ-connecting position and the position of a pressure sensor is stored in a memory part 3 by this process. The pressure PZ(R) to be applied really to the load (organ) can be calculated as the flow pressure PS(R)-PC(R) in loaded state.
