Title: Electrophotographic method
Inventor: YOKOGAWA MIKIKO
IPC: G03G5/147
Filed: 1989-09-26
Abstract: PURPOSE:To improve cleanability and to suppress the generation of blade squeaking by specifying the outside diameter and thickness of a photosensitive drum, the binder resin on a surface layer, the material and contact length of a cleaning blade, and the external additives of a magnetic one-component developer and the amt. of the additives to be added. CONSTITUTION:The photosensitive drum 10 consisting of a conductive base 11 which has <=60mm outside diameter and <=2mm thickness and the surface layer 15 of the photosensitive layer which contains bisphenol Z type polycarbonate is used as an electrophotographic sensitive body. The developer externally added with 0.02 to 1% hydrophobic colloidal silica is used as the magnetic one-component developer. A blade consisting of a polyurethane resin is used as the cleaning blade 6. Cleaning is executed while the cleaning blade 6 is kept brought into contact with the surface of the photosensitive body so as to attain contact length l =0.1 to 2.5mm. The cleanability is improved in such a manner and the surface friction resistance between the photosensitive body and the cleaning blade is lowered. The blade squeaking, etc., are thus prevented.

Title: Semiconductor integrated circuit
Inventor: SATO FUMIO
IPC: H03L7/08
Filed: 1989-09-26
Abstract: PURPOSE:To improve efficiency of frequency division ratio setting processing without increasing the number of external terminals by outputting a frequency division ratio setting data based on a selection data in an internal data signal fetched by a data output selection circuit as one selection output signal in 1st and 2nd selection output signals. CONSTITUTION:A control circuit 6a sends a control signal CS commanding the transfer of a frequency division ratio setting data D0 to a programmable divider based on a selection data D3 to a selection circuit 6b. As a result, the selection circuit 6b transfers the D0 to the said divider 1 only to change only the frequency division ratio of the divider 1. Moreover, the frequency division ratio setting of a programmable reference divider 5 is implemented similar as the frequency division ratio setting of the said divider 1. Thus, a selection data D3 requiring an input to the shift register 3' is enough to be one bit at all times, then in the case of frequency division ratio setting, the time inputting the bit data of a long bit to the shift register 3' is omitted for the generation of the undesired frequency division ratio setting data.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To maintain operability of a valve for a long period, make the temperature regulation function of a combination faucet keep long, increase reliability of the combination faucet, and reduce a cost. SOLUTION: A valve 8 is produced by molding from sintering powder of a stainless steel. After sintering, the valve 8 is coated with grease. Grease gathers an infinite number of gap holes of the valve 8, and a slide part between the valve 8 and the inner peripheral surface of an upper body 3 and a slide part between the valve 8 and the O-ring are lubricated by grease of the valve 8 for a long period. Outflow of grease is suppressed and operability of the valve 8 is maintained. Since the material of the valve 8 is made of a stainless steel, corrosion is prevented from occurring. Since the valve 8 is produced through molding work, productivity is increased and a cost is reduced.
