Title: Electrophotographic recorder
Inventor: KUNISHIGE HIDENORI
IPC: G03G15/047
Filed: 1984-12-13
Abstract: PURPOSE:To improve the consumption efficiency of a toner and to extend the life of a light source of an optical system by operating an electrostatic charge means in synchronization with the rotation of a photosensitive drum. CONSTITUTION:The photosensitive drum 1 under rotation at a constant speed is electrostatically charged to a positive polarity over the entire surface. An optical system 3 emits the light complying with the image in accordance with the input signal from the outside to expose the drum 1 after the drum 1 moves by L1 or above. The potential of the electric charge on the drum 1 decreases in the exposed part and an electrostatic latent image is formed. A developing device 4 starts functioning after the movement of the drum 1 by L2 or above and visualizes the latent image by the negative and positive reversal development of said image. More specifically, the drum 1 and the charger 2 operate synchronously and the developing device 4 starts operating after the movement of the drum 1 by the distance L2 or above. Both the drum 1 and the charger 2 stop operation. There is no sticking of the toner to the parts except the necessary developing parts. The consumption of the toner is thus decreased and the life is extended.

Title: Semiconductor sealing epoxy resin composition
Inventor: FUJIMOTO TAKAMITSU
IPC: C08G59/62
Filed: 1988-10-19
Abstract: PURPOSE:To obtain a sealing resin composition which is excellent in heat, moisture, and cold shock resistance when it is set and is prevented from deteriorating in fluidity and other properties even if it is increased in the loads of inorganic filler or modified with silicone compound to decrease in thermal stress by a method wherein the sealing resin composition is made to contain specified epoxy resin, specified phenolic novolak resin, and the like. CONSTITUTION:Semiconductor sealing epoxy resin composition of this design is composed of epoxy resin shown by a chemical formula as noted, phenolic novolak resin whose softening point is 90-130 deg.C, inorganic filler, and a curing agent, where the equivalent weight ratio of an epoxy group of the epoxy resin to a phenolic hydroxyl group of the phenolic novolak resin is set to 1:(0.8-1.2). When the equivalent weight of a phenolic hydroxyl group of the phenolic novolak resin to one equivalent weight of an epoxy group of the epoxy resin is less than 0.8, the above resin composition becomes low in glass transition temperature and decreases in moisture and heat resistance, and when the equivalent weight of a phenolic hydroxyl group of the phenolic novolak resin is larger than 1.2, the phenolic novolak resin is much left as unreacted and the resin composition decreases in moisture and heat resistance.
