Inventor: MATSUO KOZO
IPC: H01L21/60
Filed: 1988-03-23
Abstract: PURPOSE:To prevent an electrode from corroding, by sequentially forming a passivation film having an opening narrower than the extending diameter of the tip of a wire at the time of bonding and a flexible resin film in this order on the electrode, and connecting the tip of the wire to the electrode through the opening. CONSTITUTION:An aluminium electrode 3 is formed on an insulating film 2, and a passivation film 4 made of PSG, SiNx or the like and a flexible resin film 7 made of polyimide or the like are further formed on the upper part of the electrode. Openings 5 narrower than the extending diameter of the tip of a wire at the time of bonding are respectively formed at the films 4 and 7. When the bonding is completed, the extending diameter Wb of the tip of the wire is larger than the inner diameter Wh of the opening. Thus, the periphery of the opening 5 is covered with the ball at the tip of the wire 6. Accordingly, an exposed part is not presented on the electrode 3 in this state, thereby improving corrosion resistance of the electrode in an atmospheric environment.

Inventor: ABE OMIYA
IPC: F25D21/08
Filed: 1990-03-20
Abstract: PURPOSE:To contrive the improvement of reliability and the reduction of cost by a method wherein only one set among control units for defrosting is operated as a master machine having the functions of master machine and slave machines and the other units are operated as slave machines having only the function of slave machine while the address of the master machine is set at the highest order so as to be smaller than the addresses of the slave machines without any omission. CONSTITUTION:A defrosting controller 11 reads an own address set in an address setter 12 after initial setting and decides by a master and slave switching switch 13 whether the controller 11 itself is a master machine or not. When the controller 11 is the master machine, the controller outputs a defrosting command toward the slave machines having addresses lower than the own address. A defrosting controller 11, which is not set as a master function, receives the defrosting command through a communication line 20 and a communication circuit 14 and when the address is own address, the controller drives corresponding defrosting instruments 30a, 30b, 30c in accordance with a defrosting sequence. The defrosting controller 11 of a defrosting control unit, which is set as a master machine in such a manner, repeats the process of master machine function and the process of slave machine function while the defrosting controller 11 of a defrosting control unit, set as the slave machine, repeats only the function of the slave machine.

Abstract: PURPOSE:To suppress the fogging of a formed image and to improve the picture quality by decreasing the intensity of a magnetic field between a transparent electrode and a developing sleeve toward the downstream side in the rotating direction of the developing sleeve. CONSTITUTION:A magnet 43 which faces a transparent electrode drum 20 across the peripheral surface of the developing sleeve 42 is cut in a tapered shape so that the downstream side of the magnetic pole part on the side facing the drum 20 leaves the drum 20 toward the downstream side at the downstream side in the rotating direction of the developing sleeve 42. Therefore, the intensity of the magnetic field operating on the opposition area between the drum 20 and developing sleeve 42 by the magnet 43 decreases in order toward the downstream side. Consequently, the napping of a magnetic brush formed on the peripheral surface of the developing sleeve 42 is securely rubbed against the transparent electrode 20 in the opposition area and becomes conductive, so that photosensitive toner is securely scraped and separated from the drum 20. Therefore, the fogging of the formed image is suppressed and the picture quality is improved.
