摘要： PURPOSE:To prevent a sealing member from corrosion by thermal exhaust gas compounds and to stabilize it against thermal shock generated due to rinsing and others by forming at least part of the sealing member of unorganic glass and/or wear and abrasion resistance ceramic the thermal expansion coefficient of which is lower than a specific value. CONSTITUTION:The structure and material of the member in the title are specified by way of using unorganic glass and/or wear and abrasion resistance ceramic the thermal expansion coefficient of which is less than 70X10 / deg.C at least on one part of sealing parts of a radial sealing part B, an axial sealing part A and a by-pass sealing part C. And all the surfaces except for a sliding surface, supposing ceramic is used for the sliding surface, are formed of wear and abrasion resistance ceramic materially surrounded with anticorrosion steel and anticorrosion steel.

摘要： PURPOSE:To improve the durability by connecting airthight a plate-form beta-alumina to a storage container of cathode and anode active substances through a sealing material so as to form separate cells at both sides of the plate-form beta-alumina, an putting in the cathode and the anode active substances in the cells. CONSTITUTION:On both sides of a plate-form beta-alumina solid electrolyte 10, an anode metallic container 12 and a cathode metallic container 13 are connected airtight to form separate cells on both sides of the plate-form beta-alumina, and an anode active substance 14 and a cathode active substance 15 are stored in the cells respectively. As a result, the resistant force is large even to a stress at the connection generated depending on the ambient temperature variation in the operation time and in the stopped time of the cell, and there is no fear of generating breakage or damage at the connection. Consequently, a cell of large strength and excellent durability can be obtained.

摘要： PURPOSE:To prevent the leakage of silicon grease at the time of lamination by sealing the upper and lower end portions of an inner holes located at the central portion of a glass and also providing corrosion resisting partition walls between the silicon rubber and the silicon grease. CONSTITUTION:An optical fiber 3 is inserted through an inner hole 2 located at the central portion of a glass 1 and the upper and lower end portions of the glass 1 are sealed with silicon rubbers 5-1, 5-2 to prevent the flow of silicon grease 4 in the inner hole 2. Partition walls 6-1, 6-2 provided between the silicon rubbers 5-1, 5-2 and the silicon grease 4 are made of organic matter than a silicon compound such as nitril rubber, butyl rubber, urethane rubber, epoxy resin acrylic resin or the like, which is less liable to react with the silicon grease 4 and has corrosion resistance. With this arrangement, the seal is prevent from being reacted with the silicon rubbers 5-1, 5-2 and the silicon grease 4, thus it is possible to eliminate the breakage of the seal, thus preventing the leakage of the end portions of the silicon grease 4.

摘要： PURPOSE:To enable the maintenance of lighting function and air tight insulation property so as to enable free control of circumferential atmosphere of a lightning protection element by sealing in an air tight manner only conductive covers of upper and lower parts of ZnO element by using an insulator main body and inorganic glass, through partial heating by induction heating. CONSTITUTION:Inorganic glass members 5-1, 5-2 are coatedly interposed between upper and lower conductive covers 4-1, 4-2 of a lightning element 2 and ceramic 1, and after both are compressed, the conductors are induction heated and the members 5-1, 5-2 are fused and fixed, thereby the upper and lower covers 4-1, 4-2 and the ceramic 1 are joined in an air tight manner. Namely, the members 4-1, 4-2 are composed of conductive material and the members 4-1, 4-2 are induction heated by the application of high frequency induction heating. Consequently, destroy position can be set at the covers for storing a ZnO element upon pressure release operation, and extension of cracking to the insulator main body can also be prevented. It is thus possible to improve pressure release characteristic upon generation of abnormal over current short-circuit and to reduce the size of a heating device, and further to enable free control of circumferential atmosphere of the element 2.

摘要： PURPOSE:To provide a method for forming a packing capable of exchanging a packing material rapidly, readily, surely and safely and supply a device used therefor. CONSTITUTION:A small material is used as a packing material and is filled into a packing box 13 by given fluid pressure or spring force and/or vibration. The filled small material is pressed by a pushing means to form a packing 11. This device for forming the packing material consists of a small material storage chamber for preserving small materials, a fluid storage part for preserving a pressurized fluid, a first duct which connects the small material storage part to the fluid storage part to supply the pressurized fluid from the fluid storage part to the small material storage part and a small material feed hose attached to the small material storage part to project the small material together with a fluid.

摘要： PURPOSE:To increase the number of durable times of a heater and reduce the replacement frequency and at the same time automatically and continuously measure a calorifit value by transferring the heat which is generated by the heater to a specimen for combustion via a fuse member for igniting the specimen. CONSTITUTION:The coil part of a heater 15 consisting of a platinum wire is connected to electrodes 13a and 13b. A thin cylindrical fuse member 17 consisting of a wild goose skin paper is erected on a specimen B for combustion within a combustion container C and is allowed to contact the coil part of the heater 15. Then, when a calorifit value is measured and tested, the coil 15 is energized and releases heat, thus enabling the fuse member 17 to be combusted and lost easily by heat release of the heater 15 and the specimen B for combustion to be ignited and combusted during this period. The heater 15 and the specimen B are separated by a specific distance on combustion without being affected by combustion heat of the specimen B at the proximity position, thus suppressing acceleration of oxidation and thermal deterioration of the heater 15.
