Title: Laser light scanner
Inventor: NAKAMURA SATOKATSU
IPC: G02B26/10
Filed: 1990-01-30
Abstract: PURPOSE:To converge laser light into a fine spot by reflecting a parallel light beam which is made incident from the 1st focus of a semi-elliptic sphere by a mirror surface and converging it by an objective lens placed at the 2nd focus. CONSTITUTION:A parallel light source 103 is fixed in position, but freely changed in direction; and the projection point is invariably at the 1st focus and an place on the internal wall of the semi-elliptic sphere can be irradiated with the parallel beam 105. The parallel light beam 105 which is made incident from the 1st focus of the semi-elliptic sphere 101 and reflected by the internal mirror surface passes the 2nd focus without fail because of the characteristics of the focuses of an ellipse, so the objective 107 is arranged at the 2nd focus to converge the light into the fine spot 11 on the surface of a medium 109. When the angle of projection of the parallel light source is varied, the angle of incidence of the parallel light beam on the objective lens also varies, so the spot shift in position on the medium surface. Consequently, a fast random two-dimensional scan with the fine laser spot scan be made.

Title: Identifier ciphering method in radio communication
Inventor: OHASHI MASAYOSHI
IPC: H04L9/08
Filed: 1995-01-12
Abstract: PURPOSE: To effectively cipher identifier of a mobile equipment by using a public key cryptosystem so as to cipher the identifier with information specific to a network. CONSTITUTION: A mobile equipment (i) has a public key ciphering function (f) and an identifier IDi and a network generates the function (f), a time variable public key Kpn and a time variable secret key Ksn . The network generates the keys Kpn and Ksn at intervals of a prescribed time to broadcast the key Kpn without interruption. When the mobile equipment (i) makes transmission or position registration, the mobile equipment sends a signal fKpn (IDi) formed by ciphering its own identifier IDi with the key Kpn to the network and the key Kpn is used to decode and extract the identifier IDi. Since the mobile equipment (i) does not know the key Ksn , the mobile equipment cannot recognize the identifier IDi even when tap a radio channel.  Since the key Kpn is revised at intervals of a prescribed time, the result of ciphering the identifier IDi to be set in the same digit is prevented to secure time variable performance. Moreover, when the mobile equipment (i) requests time variable performance, the mobile equipment (i) generates a random number R and sends a coupling signal fKpn (IDiR) in place of the signal fKpn (IDi) to extract the identifier IDi.
