Title: Level shift circuit
Inventor: YAMASE SHINYA
IPC: H03F3/345
Filed: 1992-04-17
Abstract: PURPOSE:To make an output voltage correspond to an input voltage by common-connecting the transistor of an N channel to the transistor of a P channel to obtain an input and output terminal, and dividing a voltage between a power source and a ground to shift an input voltage level. CONSTITUTION:The gates and drains of an N channel transistor 13 and a P channel transistor 14 are common-connected in order to obtain an input terminal 11 and an output temrinal 12. And also, the voltage between a power source voltage Vdd and a ground voltage Vss is resistance-divided by resistors R11 and R12, and the result is connected to the output terminal 12. Thus, the level shift of the input voltage impressed on the input terminal 11 is operated. Therefore, the output voltage is changed in a right side rising state in response to the input voltage even in an area where the output voltage is constant. Thus, the oscillation frequency of a voltage control oscillator can be variably controlled in response to the input voltage over the whole area of the input voltage.

Title: Resin for forming electrophotographic photoreceptor
Inventor: CHOKAI AKIKO
IPC: C08G63/183
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To provide the resin for forming the electrophotographic photoreceptor having sufficient mechanical characteristics and high solubility in non- halogenated solvents by using a specified polyarylate resin as a binder resin. SOLUTION: The resin for the electrophotographic photoreceptor contains the polyarylate resin represented by the formula in which R<1> is a 1-4C alkyl group; each of R<2> -R<4> is, independently, an H atom or a 1-4C alkyl group; and m/(m+n) is 0.3-1.0. The reason why the m/(m+n) is set in this range is because the solubility in the non-halogenated solvent is extremely excessively when a proportion of terephthalic acid to that of isophthalic acid becomes very high. The photosensitive layer using this resin may be either a dispersion type or laminated type. As the photoconductive material in the case of the dispersion type, a material, such as selenium and its alloys, can be used, and these fine particles and a charge transfer material combined with the polyarylate resin are used.
