Title: Triphenylamine derivative and photosensitive substance using the same derivative
Inventor: TANAKA MASAFUMI
IPC: C07C217/84
Filed: 1991-04-12
Abstract: PURPOSE:To obtain a new phenylamine derivative having high hole mobility and being excellent also in compatibility with a binding resin capable of forming a photosensitive layer and useful as an electron transfer material, especially as a hole transfer material. CONSTITUTION:A phenylamine derivative of formula I (R<1> to R<4>, R<11>, R<21>, R<31> and R<41> are H, alkyl, alkoxy, aryl or cycloalkyl; (m) is integer of 1-10). The compound of formula I is obtained by e.g. making an aldehyde compound of formula II to react with an amine compound of formula III in the presence of acetic acid, p-toluenesulfonic acid, etc. Since a photosensitive substance using the triphenylamine derivative is excellent in antistatic ability and sensitivity and simultaneously the triphenylamine derivative is rich in compatibility with a binding resin, the photosensitive substance can obtain uniform photosensitive layer.

Title: Lip seal device
Inventor: SHIBATA MAKOTO
IPC: F16J15/324
Filed: 1990-03-28
Abstract: PURPOSE:To improve durability by forming a protrusion part, protruded from a seal surface between the protrusion and a rotary shaft toward the seal fluid side, on the tip part on the inner peripheral part side of a lip made of rubber, locating a support ring to the inner side of the protrusion part, and forming communicating passages in the support ring. CONSTITUTION:Since a seal part 5a of a first lip 5 made of runner has a seal fluid side supported by a support ring 9, the seal part is prevented from firm adhesion on a rotary shaft 2 by means of a pressure on the seal fluid side. Simultaneously, since seal fluid is fed to the seal part 5a through communicating passages 10 formed in the support ring 9, deficiency in the seal fluid serving as lubricating oil at the seal part 5a is prevented from occurring. Coupled with with support by the support ring 9, wear of the seal part 5a of the first lip 5 is effectively prevented from occurring for a long period.

Title: Digital exchange system
Inventor: TOMARU KEISUKE
IPC: H04N1/00
Filed: 1978-07-04
Abstract: PURPOSE:To secure an application for the digital exchange system in a wide range of the communication modes by allotting the comparatively short and long correspondence into the ''instant'' and ''cumulative'' modes each and then giving the priority to the instant communication mode. CONSTITUTION:The correspondence to be sent to terminal storage node TN from terminal T contains identification information 1 such as the address or the like, correspondence main body 2 plus mode identifier 3 which displays instant communication mode MO1 or cumulative communication mode MO2. Processor P of TN examinesidentifier 3 for the correspondence received from T and memorizes the correspondence in buffer memory BM1 and BM2 according to the display of MO1 and MO2. Then processor P reads out the codntents of BM1 in preference to BM2, and the contents of BM1 is sent to repeating exchange node SN via circuit control unit LC. In case the contents of BM1 and BM2 are sent to SN, the control is given through TN so that the local traffic concentration may be avoided within the  excharge network.
