Title: Safety valve for vacuum device
Inventor: OZORA HIROKI
IPC: F16K17/14
Filed: 1993-12-28
Abstract: PURPOSE:To provide a safety valve for a vacuum device without generating the blowoff and permeation of gas even in a superhigh vacuum state. CONSTITUTION:One end part of a bellows 21 is fixed to the side wall M of a vacuum container. A flange member 11 is airtightly fixed to the other end part of the bellows 21, and the outer peripheral edge part of a metal disc 12 is clamp-fixed by the flange member 11 and a fitting flange member 1. Opposed to the center part 12a of the metal disc 12, a hollow needle 14 is fixed to a stationary part. When a space V is put in the pressurized state, the bellows 21 is elongated, and the metal disc 12 is moved up and broken through by the needle tip 14a of the hollow needle 14. The leakage of gas is thereby generated. Because of not using an O-ring formed of a rubber member as in a conventional way, there is no generation of gas nor the generation of permeation even if facing an extra-high vacuum.

Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To attain the fast switching of paths and to attain the fast restoration of a whole network by detecting previously the possibility of faults other than a faulty path based on the single-fault/multi-fault detection information of a network and performing the detection of faults and the switching decision/ execution based on the detection result of possibility of faults. SOLUTION: When physically the same nodes and the paths passing through a transmission line are defined as path groups PathG (pass group), the faults are detected for every path or path group. This fault detection information is inputted in real time to a path switching control part 108. On the other hand, the information received from a PathG management table 104, a PathG relation table 105 and a PathG characteristic table 106 are previously inputted to the part 108. If a fault detection part 101 detects a fault of Path (1), the path having the fault is confirmed via the table 104 and this faulty path is fast switched.

Title: Air release valve
Inventor: ASADA TETSUO
IPC: F16K24/00
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an air release valve having large vacuum break ability and capable of quickly performing vacuum break. SOLUTION: A valve chest 3 with an inflow port 4 and an outflow port 5 opened in a lower part and an upper part, respectively, is formed by a casing constituted of a main body 1 and a cover 2. A valve seat 6 is formed between the valve chest 3 and the inflow port 5. The main body 1 integrally has a plurality of ribs 9 projecting to the inside at an inner wall of the valve chest 3. At the inside of the ribs 9, a float receiver 10 having a bottomed and almost cylindrically shaped through hole 11 of small opening area at a bottom part and a communication hole 13 of large opening area is fixed. Within the float receiver 10, a spherical float 12 is arranged in a free state. A check valve body 14 for opening/closing the communication hole 13, allowing flow from the inside to the outside of the float receiver 10 and stopping flow of an opposite direction is fixed at the outside of the float receiver 10. Because external air flowing into the float receiver 10 can be passed to the outside of the float receiver 10 by the communication hole 13 of large opening area, air seldom springs back by hitting on the bottom part of the float receiver 10 and pressure in the lower part of the float 12 within the float receiver 10 becomes difficult to rise. Therefore, the float 12 becomes difficult to float, vacuum break ability becomes large and vacuum break can be quickly performed.

Title: Shadow-mask material
Inventor: YUKI NORIO
IPC: H01J29/07
Filed: 1991-12-26
Abstract: PURPOSE:To develop an Fe-Ni shadow-mask material for the highdefinition color television picture tube having more uniform etching drillability than before. CONSTITUTION:The crystal grain size of the Fe-Ni shadow-mask material is controlled to >=9.0 fineness number, and the aggregation degree of the (100) face on the rolling surface is adjusted to <35%. The rolling and annealing history, annealing temp. before final rolling and final draft and the annealing temp. and time when final annealing is applied are controlled. Since the crystal grain size is controlled to >=9.0 fineness number, the etched hole and wall surface are smoothed. As the aggregation degree of the (100) face on the rolling surface is controlled to <35%, the crystals are oriented at random, and the etching uniformity is improved. The shadow-mask material is applicable to the high-definition color television picture tube.
