Abstract: PROBLEM TO BE SOLVED: To simplify the circuit configuration of fog lamps by employing a single switch serving as a front fog lamp switch and a rear fog lamp switch as well. SOLUTION: A control circuit 70 is adapted to light a rear fog lamp on when a switch 60 is flicked so that its movable contact 60A comes into contact with its fixed contact 60B and a switch 62 is flicked so that its movable contact 62A comes into contact with both its fixed contacts 62B and 62C, and to light the fog lamp off when the switch 60 is turned off with the switch 62 held still on in which the movable contact 62A is held in contact with both the fixed contacts 62B and 62C. With the fog lamp being off in that way, the circuit 70 keeps the fog lamp off even when the switch 60 is flicked on again so that the movable contact 60A comes into contact with the fixed contact 60B.

Title: Watertight gun for underwater stud welding
Inventor: HAMAZAKI MASANOBU
IPC: B23K9/00
Filed: 1981-07-30
Abstract: PURPOSE:To obtain a watertight gun for underwater stud welding free from leakage of compressed gas by housing the body of a welding gun in a watertight housing and elastically sealing the bearing of an operation shaft. CONSTITUTION:The body of a gun for stud welding that uses a ferrule is enclosed airtightly by a watertight housing 2 provided with a cylindrical part 6 enclosing a stud 15. An operation shaft 3 to which a ferrule holding part 6 and a stud chuck 23 are attached is installed in the cylindrical part 6, and allowed to go in and out by arc length. An elastically sealed part 4 is provided in the bearing 30 of the gun body side of the operation shaft 3. Compressed air is sent from an air supply pipe 29 to inside of the housing 2 and the cylindrical part of the housing. The elastic seal 4 has non-return sealing action, and when internal pressure of the housing 2 is made higher than surrounding water pressure, compressed gas leaks out from the sealed part 4 in a quantity suitable for lubrication. By this way, inside and outside of the housing 2 are kept at very small differential pressure. Interference to the operation shaft is eliminated and welding quality is improved.

IPC: G02F1/03
Filed: 1990-05-10
Abstract: PURPOSE:To improve the light energy efficiency by interposing a 3rd reflecting mirror between a 1st reflecting mirror and electrooptic crystal and connecting a driving power source whose optical driving period is set to the reciprocation period of light between the reflecting mirrors or the reciprocal-of-an-integer multiple of the period, to the electrooptic crystal. CONSTITUTION:An ultra short light generator main body 10 consists of three partial transmission type high reflecting mirrors M1 - M3, an optical phase modulator 11 which is interposed between the reflecting mirrors M2 and M3, and the driving power source 12 which drives the optical phase modulator at a period equal (nearly equal) to the period of the reciprocation of light between the reflecting mirrors M2 and M3 or the reciprocal-of-an-integer multiple of the period. For the purpose, the resonator length of an input resonator FC is so set that almost all of input light is transmitted, but the side band is nearly reflected; and the transmission sharpness finesse value is made large and then the side band generated in a modulating resonator MC can be led only a little out of the modulating resonator MC. Consequently, the light energy efficiency can be improved.

Title: Cryptographic key common provision control system
Inventor: TORII NAOYA
IPC: H04L9/14
Filed: 1989-05-15
Abstract: PURPOSE:To make the perception of a cryptographic key almost impossible even when the 3rd party intercepts the information by using a secret parameter in the center so as to form secret information corresponding to entity and allowing the entity to use the secret information, its own password and an identification number of a communication party so as to form a cryptographic key KEY. CONSTITUTION:Based on the least common multiple L of (p-1), (q-1), where p, q are primes, a value M smaller than the product (n) between the primes p, q, a value (c) smaller than the least common multiple L, the identification number of the entity and a password are used to form secret information corresponding to the entity. Based on the secret information, each entity uses the password of its own entity and the identification number of the opposite entity to generate a cryptographic key, which is used as a common cryptographic key. Then the secrecy storage information storing the primes p, q and the least common multiple L in secrecy is formed. Thus, the decoding of the secrecy information is disabled even with the conspiracy of the entities.

Title: Communication system and communication unit
Inventor: HATAKEYAMA TAKESHI
IPC: H04W92/10
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To avoid collision of addresses in a communication system for recognition where a communication terminal returns a replay packet with respect to a recognition packet from a recognition terminal, the recognition terminal transmits an ACK packet with respect to the reply packet and a terminal receiving the ACK packet does not transmit any reply packet. SOLUTION: A communication terminal receiving a recognition packet from a recognition terminal transmits a reply packet through a random slot. In the case the recognition terminal can normally receive the reply packet, the recognition terminal transmits an ACK packet including information of an address and a slot number of the communication terminal. The communication terminal that transmits the reply packet with the same address but with a different slot number with respect to the preceding recognition packet decides the address again. Thus, even when the addresses of communication terminals having been decided at random collide with each other, the recognition terminal can recognize all communication available communication terminals.
