Title: Electrophotographic sensitive body
Inventor: SHIMADA AKIRA
IPC: G03G5/08
Filed: 1986-05-15
Abstract: PURPOSE:To increase the photosensitive of a sensitive body to light having longer wavelength such as semiconductor laser light by interposing a thin amorphous Si layer having wider optical band gap and a higher specific resistance than the amorphous Si layer between the two amorphous Si layers of the sensitive body. CONSTITUTION:A substance having a relatively wide optical band gap and a high specific resistance is used to form a protective surface layer 3 on the surface of a sensitive body 1 or a blocking layer 8 on the interface between the sensitive body 1 and a substrate 2. The surface layer 3 prevents the implantation of electric charges given to the surface of the sensitive body 1 by corona discharge into the sensitive body 1 and prevents the lowering of the resolution of an electrophotographic image. The blocking layer 8 prevents the implantation of carriers into the sensitive body 1 from the substrate 2 and enhances the time constant of dark attenuation. The carrier transferring layer 7 is doped with boron so as to increase the specific resistance and to improve the travellability of positive holes. When a very thin film having a wider optical band gap and a higher specific resistance is interposed between the light absorbing layer 5 and the carrier transferring layer 7, the sensitivity in a longer wavelength region can be increased.

IPC: C23C14/14
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To facilitate production while increasing the yield by performing a bombard processing while covering a part where a thin metal based magnetic film is not formed in a thin metal based magnetic film forming process thereby preventing nonmagnetic supports from adhering each other at the time of winding in the process to cause breakage or stripping at the time of feed out.

It is performed on the surface of a nonmagnetic support for forming a thin metal based magnetic film using a plasma of O2 , Ar or N2 prior to formation of the thin film. The cover for forming a part not subjected to bombard processing is provided at the fringe part on the opposite sides of the nonmagnetic support where the thin film is not formed, between a part where a plasma is generated through discharge and the nonmagnetic support, such that the surface at the fringe part on the opposite sides of the nonmagnetic support is prevented from being processed with plasma and activated.

Title: Treatment of coke-oven liquor by nitrification liquid circulating method
Inventor: TOKI SHINGO
IPC: C02F3/34
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To stably reduce NOx-N produced during a purifying treatment of a coke-oven gas liquor (ammonia liquor) by a biological nitrification denitrification method. SOLUTION: In this treatment of the ammonia liquor using an activated sludge for removing nitrogen also, the ammonium liquor is introduced into the first denitrification tank A being an anaerobic atmosphere, then a nitrogen- containing matter is nitrified in a nitrification tank B, and denitrified in the second nitrification tank C being the succeeding stage of the nitrification tank B while a nitrification liq. is circulated from the nitrification tank B to the first denitrification tank A.  The NOx-N concn. in a treated water is stably reduced by attaining >=98% nitrification ratio of the ammonium liquor in the nitrification tank B (for example, cyan, hydrogen sulfide and oil having toxicity to a nitrifying bacteria are removed by bubbling or settling before introducing the ammonium liquor into the denitification tank A), and the nitrification in a deaeration tank D is eliminated, thereby preventing the floating due to denitrification in a precipitation tank E and the COD increase of the treated water.
