  • Patent number: 11834210
    Abstract: A binding machine includes a feeding device configured to feed a binding material, a movement passage through which an object to be bound to be moved to a binding executing position passes, a movable member configured to be moved from a premovement position where at least a part thereof is disposed in the movement passage, by being pushed by the to-be-bound object when the to-be-bound object moves toward the binding executing position, a winding member configured to wind the binding material fed to a given position by the feeding device around the to-be-bound object, by rotating while being transmitted power of the movable member moved from the premovement position, and a twisting device configured to twist the binding material wound around the to-be-bound object by the winding member.

  • Patent number: 6342547
    Abstract: There is provided an epoxy resin composition, which has superior resistant property to SF6 gas, mechanical strength and cracking resistance in a well balanced manner and which can provide an insulating molded article having a low dielectric constant. The epoxy resin composition for an SF6-gas insulating device of the present invention is obtained by adding a silicate compound powder to an epoxy resin.

  • Patent number: 5990440
    Abstract: A switch containing a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc.

  • Patent number: 5180532
    Abstract: Mica-containing ceramic composite having excellent characteristics such as capability of machining work, a small thermal expansion coefficient, high heat-shock resistant temperature difference as well as high heat deformation temperature, is prepared by: a) preparing powder mixture by blending 20 to 50% by weight of mica powder, 15 to 40% by weight of zinc oxide powder, 10 to 20% by weight of silica powder, 8 to 20% by weight of boric acid powder, and 4 to 20% by weight of cordierite powder; b) heating the powder mixture at a temperature of from 940.degree. C. to 1,050.degree. C. to prepare baked product; c) pulverizing the baked product into very fine powder to thereby obtain a shaping material; d) adding an organic binder to the shaping material to prepare a shaping composition; and e) shaping the shaping composition into a shaped body and heating a shaped body at a temperature ranging from 940.degree. C. to 1,050.degree. C.

  • Patent number: 4746346
    Abstract: A method for producing an air-tight, heat-resistant plate for a particular use in manufacturing bulbous fluorescent lamp, which comprises: preparing a shaping material by mixing an inorganic filler composed of alumina powder and silica powder in a specified compositional ratio, and glass powder having a thermal expansion coefficient of 8.5 to 11.5.times.10.sup.-6 /.degree.C., both inorganic filler and glass material being blended at a predetermined ratio then, forming the shaping material into a shaped product of any desired configuration by a known shaping method; thereafter heating this shaped body to a temperature, at which the glass powder used becomes molten and fused, thereby rendering it to be a burned body.
