Title: Vacuum pump
Inventor: USAMI TOSHIKAZU
IPC: H02K5/10
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a vacuum pump by providing an inundation-prevention sheet at the end of a through hole formed through a casing to prevent the penetration of leakage oil from oil seals thereinto and discharge the oil to the outside as well as to prevent the inundation from the outside thereinto. SOLUTION: In the space between oil seals 9a and 9b and an oil seal 9c, a through hole 5b is formed through a casing 5 for discharging leakage lubricating oil from the oil seals 9a and 9b to the outside. A sheet 10 with its smallest- diameter portion being larger than the bore of the through hole is provided at the end of the through hole 5b with an interval therebetween. Leakage lubricating oil from the oil seals 9a and 9b is sealed off by the oil seal 9 and is then discharged through the through hole 5b to the outside. The discharge of the leakage lubricating oil prevents the tearing of a belt for transmitting engine torque caused by the deposition thereon of leakage lubricating oil lead toward a pulley 8.

Title: Roaming system
Inventor: TOMOIKE HIROMOTO
IPC: H04L9/30
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a roaming system which can perform roaming processing, without notifying proper information about a subscriber number and a terminal of an authentication key, etc., to a roaming bound network. SOLUTION: A roaming terminal 10 encrypts a subscriber number MSN with a public key Kpa of a home network and sends it to a home network 30 through a roaming bound network 20. The network 30 decodes cipher with a secret key Ksa, acquires the MSN and an authentication key Sa, which is temporarily generated with a public key Kp1 of a terminal which corresponds to the MSN. When the key Sa is notified to the network 20 and an encrypted authentication key is notified to the terminal 10, the network 30 authenticates a terminal by using a random number which is generated and using these authentication keys. When authentication is completed, the network 20 acquires a roaming number and notifies it to the terminal 10 and the network 30. The terminal 10, the networks 20 and 30 separately store the roaming number and the authentication key.

Title: Photoconductive polymer, its production and electrophotographic sensitive body formed by using the same polymer
Inventor: NISHIGUCHI TOSHIHIKO
IPC: C08F12/26
Filed: 1988-06-29
Abstract: PURPOSE:To improve film formability, light transmittability and stability by providing a specific rhodanine deriv. having a low molecular hole transfer material as a substituent to the side chain of a chain high polymer. CONSTITUTION:This polymer has the rhodanine deriv. which has the low molecular hole transfer material as the substituent and is expressed by formula I. The absorption of visible light is by formation of an intra-molecular charge transfer type complex. Namely, the polymer has the low molecular hole transfer material via a conjugation system in the 5th position of the rhodanine ring and, therefore, the light energy is absorbed and a color is formed at the time when the pi electrons non-localized in the low molecular hole transfer material section of the ground state transfer to the unoccupied orbital of the rhodanine ring part. A photocarrier is generated by this light stimulation. The film formability, light transmittability and stability are improved in this way.
