Title: Common key setting device for code unit
Inventor: UIRIAMU FURIIDORITSUCHI AASAMU
IPC: H04L9/14
Filed: 1978-12-05
Abstract: This invention concerns a multiple domain data communication method and network. 
<??>An embodiment of the invention provides communication security for data transmissions between different domains of a multiple domain communication network where each domain includes a host system i, j, k and its associated resources of programs and communication terminals T. The host systems and communication terminals include data security devices 11, X each having a master key 13 which permits a variety of cryptographic operations to be performed. When a host system in one domain wishes to communicate with a host system in another domain, a common session key is established at both host systems to permit cryptographic operations to be performed. This is accomplished by using a mutually agreed upon cross-domain key known by both host systems and does not require each host system to reveal its master key to the other host system. The cross domain key is enciphered under a key encrypting key designated as the sending cross domain key at the sending host system and under a different key encrypting key designated as the receiving cross domain key at the receiving host system. The sending host system creates an enciphered session key and together with the sending cross-domain key performs a transformation function to reencipher the session key under the sending cross domain key for transmission to the receiving host system. At the receiving host system, the receiving host system using the receiving cross-domain key and the received session key, performs a transformation function to reencipher the receives session key from encipherment under the sending cross domain key to encipherment under the receiving host system master key. With the common session key now available in usable form at both host systems, a communication session may be established and cryptographic operations can proceed between the domains of the two host systems.

Title: Laser oscillator
Inventor: OGIYUU HISAO
IPC: H01S3/02
Filed: 1978-12-04
Abstract: PURPOSE:To prevent laser light from leaking when a laser waveguide falls off a waveguide fitting window of a laser oscillator, by providing the window with a shielding member for opening or closing the fitting window by detaching or attaching the laser waveguide. CONSTITUTION:The front wall of the body 1 of a laser oscillator has a fitting window 4, to which the connector 3 of a laser waveguide 2 is removably coupled. A shielding member 9 is provided inside the window 4 to open or closs it. When the connector 3 of the waveguide 2 is fitted in the window 4, the shielding member 9 is pushed up by the connector so that the waveguide 2 communicates with an oscillation tube 5. When the waveguide 2 falls of the window 4, the shielding member 9 goes down into contact with the inside surface 10 of the body 1 of the laser oscillator to close the window 4. Therefore, laser light does not directly leaks to the outside even if the laser oscillator is driven as the waveguide 2 remains off the window 4 or even if the waveguide falls off the window during the operation of the oscillator.

IPC: B60H3/02
Filed: 1985-07-10
Abstract: PURPOSE:To aim at uniforming the supply amount of water to a heat accumulating material so that it is possible to promote heating operation and to enhance the capacity of heating, by disposing a water humidifier for dispersing water into air passing through an air passage in order to feed water, in the air passage upstream of a heat accumulator. CONSTITUTION:Since engine cooling water is not sufficiently warmed up during starting of an engine 11, it may be not so much expected to use engine cooling water to heat air for heating the passenger's compartment. Accordingly, at that time, a control valve 22 is opened to feed water from a water supply tank 21 to a water humidifier 17 through a pipe line 20. The humidifier 17 evaporates or atomizes water, and disperses the same into air in an air passage 16. Further, the thus dispersed water is fed uniformly into a heat accumulator 15 to be made into contact with a heat accumulating material 14 after passing through a filter-like material 19. With this arrangement water in air uniformly absorbed into the heat accumulator 14 to radiate heat, and with the heat air is heated for heating the passenger's compartment.
