Title: Output noise prevention circuit
Inventor: YAMAMOTO MINORU
IPC: H03K17/16
Filed: 1988-07-21
Abstract: PURPOSE:To prevent ringing at an undershoot side from being generated by adding an input voltage directly on the gate of a p-channel transistor, and adding it on an n-channel transistor via a time constant circuit with a variable time constant in which the time constant is set at a low value first when an output voltage falls and is gradually increased afterwards. CONSTITUTION:When an input voltage Vin changes from an L to an H, accordingly, the output voltage Vout changes from the H to the L, the time constant of a circuit TC is set at the low value first, and as for transistors Q1 and Q2, the Q1 is turned off and the Q2 is turned on immediately by adding the input voltage Vin. As a result, the output voltage Vout falls rapidly, however, the time constant of the circuit TC goes higher, and the complete turning on of the transistor Q2 is delayed. According to the above state, the output voltage Vout falls moderately, therefore, no ringing is generated. In such a way, it is possible to suppress the ringing at the undershoot side without affecting on the function of an output buffer.

Filed: 1986-08-05
Abstract: PURPOSE:To always satisfactorily earth a photosensitive body at the time of normal copying by providing a switch mechanism, which is switched with elasticity, between the photosensitive body and the immobile part of a bearing provided around a drum shaft. CONSTITUTION:Since a switch 9 in a flange is separated from a bearing 4 at the time of setting a corotron current, the corotron current is conducted to the earth through a photosensitive body 1, an earth contact 5, and a resistance 6 and can be measured by a voltmeter V. Consequently, the corotron current is set to a desired value if a high voltage power source 11 is so controlled that the value on the voltmeter V is a prescribed value. Meanwhile, the switch 9 in the flange is elastically brought into contact with the bearing 4 at the time of non-setting of the corotron current, namely, normal copying. Thus, the photosensitive body 1 is always satisfactorily earthed through a drum flange (conductive part) 8, the switch 9 in the flange, the bearing 4, and a drum shaft 2.

Abstract: PURPOSE:To easily obtain sufficient exciting light power by providing a means which inputs and outputs signal light to and from an optical path different from the optical path of exciting light in a laser oscillator consisting of a light excited type optical amplifier, an optical amplifier for excitation, and an optical resonator. CONSTITUTION:The optical amplifying device consists of the optical amplifier 302, the amplifier 303 for excitation which has an amplifying function while having wavelength for exciting the optical amplifier 302, and the laser resonator 305 which includes those two amplifiers and can oscillate with the exciting light wavelength. Then signal light 61 is inputted to the optical amplifier 302 by using an optical path different from the optical path of the exciting light.
