Title: Electrophotographic sensitive body
Inventor: MIYAMOTO EIICHI
IPC: G03G5/06
Filed: 1991-11-28
Abstract: PURPOSE:To provide the photosensitive body having high sensitivity and excellent durability by providing a photosensitive layer contg. a specific azo compd. on a conductive base material. CONSTITUTION:The photosensitive layer contg. the azo compd. expressed by formula is provided on the conductive base material. In the formula, (m) and (n) respectively independently denote 1 or 2; R<1> denotes a hydrogen atom, halogen atom, alkyl group, sulfoxide group, etc.; A denotes a coupler residue without having a donor property. Since the bisazo pigment expressed by the formula is formed by fixing the core part and the coupler residue part exhibiting the donor property and introducing the coupler residue having an acceptor type substituent into another coupler residue, a deviation in the electron density distribution of the molecule is generated, by which the improved sensitivity is obtd. Namely, the polarization of the molecule in the excited state is increased by the deviation in the electron density distribution of the molecules, by which the improved charge generating efficiency by the intensity of the internal polarization of the pigment and the improved efficiency of implanting carriers into the charge transfer material are obtd.

Title: Information processing system, device and its controlling method
Inventor: HAMAGUCHI KAZUMASA
IPC: G06F12/08
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To reduce processing quantity for maintaining cached data in a cache memory, in a system to which plural nodes are connected by a bus to which the cache memory is not directly connected. SOLUTION: An information system consists of plural processors and plural nodes which are connected via a bus and include the cache memory that is attached to each processor. In such cases, tag information is attached to each data block which is stored in the cache memory. Bits 3 and 4 of the tag information hold state information that includes information (internode-shared) which shows that the data block is cached in other nodes. When a right access to the data block in the cache memory occurs, and when state information that is added to the data block is internode-shared, other nodes are requested to make the data block invalid.

IPC: C23F1/08
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent polluted atmosphere from flowing in through an overflow piping. SOLUTION: The lower end of an overflow piping 50 connected with a treated waste liquid tank 30 is brought into contact with a treated waste liquid stored in a treated waste liquid storage chamber 61 in a trap tank 60. The treated waste liquid in the treated waste liquid tank 30 is introduced from a first waste liquid piping 581 into the treated waste liquid storage chamber 61. When the treated waste liquid is flowed into the treated waste liquid storage chamber 61, the treated waste liquid is overflowed in the waste liquid chamber 62 and drained into a second waste liquid 582. Polluted atmosphere from the second liquid piping 582 is shut off by the treated waste liquid stored in the treated waste liquid storage chamber 61 and not flowed into an overflow piping 50.  The treated waste liquid in the treated waste liquid storage chamber 61, therefore, is replaced every time of replacement of treated waste liquid in the treated waste liquid tank 30, and the crystallization of treated waste liquid is not generated in the treated waste liquid storage chamber 61.
