Abstract: PURPOSE:To improve fatigue resistance by using a specified sintered material as the lead bronze bearing alloy layer of a plain bearing of three-layer structure consisting of a steel back plate, the lead bronze bearing alloy layer, and a lead alloy overlay, and specifying the refining ratio and Vickers hardness of the Pb phase dispersed in the layer section tissue. CONSTITUTION:As the lead bronze bearing alloy layer of a plain bearing of three-layer structure consisting of a steel back plate, the lead bronze bearing alloy layer and a lead alloy overlay, the sintered material of a preliminarily allowed powder consisting of 5-9wt.% of Sn, 15-25wt.% of Pb, and the remainder Cu is used. The dimension of Pb particles dispersed in the Cu-Sn matrix of its layer section tissue is set to 0.1% or less in Pb phase refining ratio represented by an equation I when the whole area is 0.1mm<2>, and its Vickers hardness is set to 100 or more. Sn is alloyed with Cu to enhance the strength of the matrix, Pb has lubricating effect, and the alloy layer strength is more improved as the Pb phase refining ratio is more finely dispersed.

Title: Separation claw device of copying machine
Inventor: YOSHIYAMA TSUGIHITO
IPC: G03G15/14
Filed: 1988-02-25
Abstract: PURPOSE:To prevent adhesion of the unfixed toner on transfer paper to a separation claw for separating transfer paper from a photosensitive body by holding the separation claw at the same potential against a copying machine body or at the potential of the same polarity as that of developing toner. CONSTITUTION:At the timing when the leading end of transfer paper P is about to reach the vicinity of a separation charger 8, a separation claw 11 is pressurized contact with a photosensitive drum 1 and the leading edge of the transfer paper P is separated from the drum 1. When the leading edge of the paper P passes the claw 11 by about 5cm, the pressure-contacting state of the claw 11 to the drum 1 is cancelled. At the time of the cancellation, a negative voltage E, the polarity of which is the same as that of the toner used for development by means of a developing device 6, is applied across the claw member 22 of the separation claw 11. Therefore, the toner is electrostatically repulsed by the claw member 22, even if the transfer paper P is attracted by the member 22. Therefore, the unfixed toner on the transfer paper P does not adhere to the claw member 22 and disturbance of the picture on the transfer paper P can be prevented.

Title: Switching circuit
Inventor: HASHIMOTO SEIICHI
IPC: H03K17/60
Filed: 1982-03-18
Abstract: PURPOSE:To avoid a control signal from being outputted to an output terminal of a switching circuit, even if an input signal and the control signal are inputted from a common input, by outputting the input signal inputted to the 1st input terminal of the 3rd input terminal of a gate circuit, when a voltage comparison circuit outputs the 2nd reference voltage. CONSTITUTION:V1 is an input signal source, and R1 is an output impedance of an input signal source, and an input signal is inputted to an input terminal Vin of an integrated circuit. V2 is a control signal source and coupled to a base of a transistor (TR)T1 via a resistor R2. The input signal inputted to the input terminal Vin is outputted to an output terminal Vout in an average potential E1-2VBE with a TRT7 when a TRT3 is conductive, and a DC potential, that is E1-2VBE, is outputted with a TRT8 via a resistor R5 and a TRT9 when the TRT3 is interrupted. Thus, the average potential is unchanged even if the switching circuit is switched and if a control signal is lost, since it is when the input terminal  reaches the bias potential that the switching circuit is changed over, no control  signal appears at the output terminal.
