IPC: G03G5/082
Filed: 1987-05-11
Abstract: PURPOSE:To obviate toner fogging between solid images by specifying the thickness of a surface protective layer consisting of Se and As to a specific range. CONSTITUTION:A photosensitive body to be used for development by a developing method by splashing with a DC electric field is constituted by laminating an electric charge transfer layer 11 mainly consisting of Se, an electric charge generating layer 12 mainly consisting of Se and Te and the surface protective layer 13 mainly consisting of Se and As successively on an Al substrate 10. The thickness of the layer 13 is specified in a 2-4mum range. The fogging between the solid images is generated if the thickness of the layer 13 is 1mum. A residual potential increases and such increase is undesirable if the thickness thereof is 5mum. The thickness of the layer 13 is, therefore, required to be 2-4mum and the sharp print having no fogging between the solid parts is obtd. if the thickness is within this range.

Title: Intermittent operation type automatic control unit

IPC: G05B11/36
Filed: 1979-09-08
Abstract: PURPOSE: To ensure a high-accuracy automatic control, by always setting the control action by the feedback to the servomotor into one direction.  
     CONSTITUTION: The switch 23 is turned on to drive the servomotor M by the detection value given from the sensor 2, and thus the time limit relays TD 1  and TD 2  operate to supply a certain voltage E b  to the servo-amplifier A i . By the function of the time limit relay, the motor M turns for a fixed time in the Q direction. As the motor M gives an extraordinarily large shift to the contacts 5 and 6 of the slide resistance, the deflection voltage ΔE c  on the slide resistance RC becomes abnormal to turn off the relay contact 22. Then the time limit relay has a release to apply the control voltage ΔE i  to amplifier A 1 , and the motor M is turned in the full speed into the N direction where the ΔE i  is turned zero.

Abstract: PURPOSE: To improve processing accuracy and the durability of an apparatus in textile sealing, etc., by pressing an ultrasonic energy transmission horn to a workpiece for a specified period and changing the power transmitted from the horn to the workpiece by a control signal during this time. CONSTITUTION: This resonance horn 19 to be pressed to the workpiece is connected to an electro-acoustic transducer 18 in the case, for example, the welding of the rigid thermoplastic workpiece is carried out. This electro-acoustic transducer 18 is connected by a conductor 17 to a wattmeter 20. The wattmeter 20 is connected to by a conductor 16 to a power source 8. As a result, the electric power is supplied from the power source 8 to the electro-acoustic transducer 18 and the ultrasonic energy is supplied from the horn 19 to the workpiece. The supply electric power of this time is detected by the wattmeter 20 and the signal corresponding to the power applied to the transducer 18 is outputted to a comparator and a latch circuit 21.  When this input signal exceeds the variable reference signal inputted from an adjustment controller 22, a signal is outputted to an electric power control circuit 500 to control the power source 8, by which the moving amplitude of the horn 19 is changed.
