Title: Cipher device and inter-terminal communication method using the cipher device
Inventor: TAKARAGI KAZUO
IPC: H04L9/08
Filed: 1994-11-04
Abstract: PURPOSE: To reduce the load on a key management center, to facilitate ciphering of a secret key by means of an IC card, and to reduce the processing quantity and time even in a broadcast cipher communication mode. CONSTITUTION: A key manager 113 writes a secret key 126 into an external memory 111 and carries it to an IC card 106. When the secret key 126 is inputted to the card 106 from the memory 111, the key 126 is ciphered by a stored master key 121 and a card specific number 129. This ciphering result is outputted. A ciphered key 125 is written into an external memory 110 and managed by a user 130. When the user 130 performs the cipher communication with another user 131, the key 125 stored in the memory 110 is inputted to the card 106 and then coded and stored by the key 121 and the number 129. Then a session key is generated for the cipher communication and ciphered by the key 126. The session key is sent to the opposite party of communication, and the card 106 receives the ciphered session key and acquires a session key against the one that is decoded by the key 126.

Title: Gas laser oscillator
Inventor: YAMANE SHIGEKI
IPC: H01S3/0975
Filed: 1989-11-14
Abstract: PURPOSE:To minimize reflected electric power, most efficiently take out laser beams, and hence reduce running cost within a service electric power range by providing a parallel plate electrode as an electrode on the outside wall of a discharge tube and increasing the width of the electrode larger than the outside diameter of the discharge tube as specified. CONSTITUTION:A pair of parallel plate electrodes 15 and 16 made of metal are installed to the outside wall of a discharge tube 1. The width of the electrodes 15 and 16 are 1.5 to 4 times as large as the outside diameter of the discharge tube 1. Since the area of the electrodes 15 and 16 is larger than that of the discharge section, load impedance is not subjected to much change in a matching circuit even when electric input changes, because the impedance in parallel with the electrodes is great when the impedance in a discharge space is subjected to change.
