Title: Packet switching device
Inventor: TANIGUCHI JUN
IPC: H04L45/247
Filed: 1994-03-31
Abstract: PURPOSE:To easily manage the set information content for a transit route between outgoing and incoming switching devices without increasing it by defin ing a transit route between outgoing and incoming switching devices by continu ous connection of a transit route between adjacent switching devices and a transit route between outgoing and incoming switching devices. CONSTITUTION:When a packet is repeated from a packet switching device 1 to a packet switching device 4, a transit route between the outgoing and incoming switching devices (SDROT) 15 to the device 4 recognizes it as a transit route (ROT) 6 between the adjacent switching device of a transit line 6. The recognition number is stored in the ROT information area of an outgoing packet and is set to the transit line 6. A switching device 2 which accepts the packet recognizes the correspondence of the ROT 12 to the SDROT 20 for the device 4, rewrites the ROT information area and transmit it to a transit line 10. The transit switching device repeats the similar operation and repeats the packet to the address device 4. The connection of the transit line 6 to ROT 12 to device 2 to SDROT 20 is the SDROT structure information. Thus, the information to be managed can be reduced.

Title: Two-crystal spectroscope
Inventor: KOKAMA TETSUO
IPC: G21K1/06
Filed: 1990-03-13
Abstract: PURPOSE:To prevent outgoing light from shifting in position irrelevantly to the wavelength of monochromatic light which is guided out as the outgoing light by fixing the position of one crystal and moving the position of the other crystal according to variation in the the angle of incidence of incident light. CONSTITUTION:The 1st crystal 1 is fixed in position and rotatable around the axis 5 of rotation in a plane parallel to the crystal surface. The 2nd crystal 2 is movable on a guide rail 7 on the same axis with the outgoing light which is parallel to the incident light 3 and at a distance H from the axis 5 of rotation of the crystal 1. Further, the axis 8 of rotation of the crystal 2 is present at the intersection of the axis of movement of the crystal and the crystal surface in parallel to the plane. When the monochromatic light having wavelength lambdais extracted as the outgoing light 4 from the incident light 3, the crystal surface of the crystal 1 is set at a Bragg angle thetaB to the incident light and at this time, the crystal 2 is set having the crystal surface in parallel to the crystal 1. Consequently, the axis of rotation of the crystal 2 is so controlled as to move from the intersection P of the perpendicular to the outgoing light 4 from the axis of rotation of the crystal 1 and the outgoing light 4 by a dis tance X satisfying a specific expression.

Title: Steam generator
Inventor: KAWAKAMI HIROTO
IPC: F22B1/06
Filed: 1989-03-17
Abstract: PURPOSE:To restrict a sodium-water reaction to be as small as possible by a method wherein in case of an occurrence of trouble of sodium-water reaction, a sealing member arranged in a water supplying chamber is moved toward a feedwater inlet port of a heating tube so as to prohibit a flowing-in of feedwater and a steam relief valve arranged at a steam water chamber is opened to release steam within the thermal conducting pipe. CONSTITUTION:Sodium acting as a secondary cooling agent enters from an inlet nozzle 35 into a barrel 31, descends while exchanging heat with a heating tube 32 and then flows out of an outlet nozzle 36. In turn, water flows from a feedwater pipe 43 into a water supplying water chamber 33, is distributed to each of heating tubes 32, collected in a steam water chamber 34 and then is sent through a steam pipe 57 to a steam turbine. In case of a trouble of sodium-water reaction, a separating mechanism 40 is provided in order to separate the supplying water chamber 33 from the steam water chamber 34. A driving shaft 48 is pushed down by a piston arranged within a driving device 49 for the separating mechanism 40, a lower end of a seal member 46 is moved down to a bottom plate of a cylinder 38 so as to separate the heating tube 32 from the supplying water chamber 33. Simultaneously with the operation of the separating valve, the steam relief valve is operated to release steam and at the same time the feedwater is drained through a blow valve. Thus, water within the supplying water chamber is released from the blow valve and steam in each of the heating tube 32 is released from the steam releasing valve into a surrounding atmosphere and the sodium-water reaction is restricted to be as less as possible.
