Abstract:
The hermetically sealed electrical feed-through device has a circular metal disk (11) with a conductive angular or bent isolated pin (13) hermetically sealed in an oval or elliptical through-going opening (O) whose center coincides with the center of the circular metal disk. The angular or bent isolated pin (13) is sealed in the oval or elliptical opening (O) by means of a glass-to-metal seal (17). An angular or bent ground pin (15) is connected to the rear side of the circular metal disk (11) adjacent to the opening (O) and extends approximately parallel to the isolated pin (13). Because the through-going opening (O) has an elliptical or oval cross-section section, different bridge wires of different lengths are connectable on the front side of the metal disk (11) between the front surface of the circular metal disk (11) and the angular or bent isolated pin (13). The isolated and ground pins both have circular transverse cross-sections.
Abstract:
This invention aims to provide a through terminal capable of maintaining air-tightness stably and an X-ray tube having the through terminal. The through terminal comprises a tubular member, a plate member formed of an insulating ceramic material and bonded to an inner periphery of the tubular member in a hermetically sealed state, and pins extending through the plate member so that the portions thereof fitted through the plate member are located inside metallic tubes respectively and bonded to the plate member in a hermetically sealed state through the tubes. The tubular member is provided on an inner periphery thereof with a stepped portion for abutment thereagainst of a plate face of the plate member. The tubular member is formed of an alloy comprising at least iron, nickel, and cobalt.
Abstract:
A circular fluorescent lamp comprises a light-transmitting circular tube, filled with a discharge gas including mercury and a rare gas, having an outer diameter between about 14 mm and 18 mm. A phosphor layer is coated on the inner surface of the light-transmitting circular tube. A stem seals each end of the light-transmitting circular tube air-tightly, and holds a pair of conductive wires. One of the ends of each pair are connected to a filament, and the other of the ends extend outwardly from the circular tube. A lamp base is arranged between the ends of the light-transmitting circular tube so as to rotate slightly around the center axis of the circular tube and includes conductive pins, which are connected to the conductive wires. An insulator, arranged between at least one pair of the conductive wires, limits the movement of the conductive wires. The circular fluorescent lamp may be used for a lighting fixture.
Abstract:
The hermetically sealed electrical feed-through device has a circular metal disk (11, 21) with a conductive isolated pin (13, 23) hermetically sealed in a through-going circular opening (O, Onull) by a glass seal (17, 27) and a conductive ground pin (15, 25) connected with a rear side of the metal disk (11, 21) adjacent to the through-going circular opening and extending approximately parallel to the isolated pin. The isolated pin (13, 23) has an oval or elliptical section (13a, 23a) extending through the glass seal (17, 27), whereby different bridge wires of different lengths are connectable on the front side of the metal disk between the front surface of the metal disk and the isolated pin (13, 23). In one embodiment the pins are straight and the through-going circular opening is offset in the metal disk; in another embodiment the pins are bent and the through-going circular opening (O,Onull) is centrally positioned in the metal disk (11,21).
Abstract:
A hermetically sealed compressor assembly including a housing, an electric motor disposed in the housing, a compression mechanism disposed in the housing and operatively coupled to the motor, a cover attached to the housing and including an integral fitting having at least one clip therein. The clip is structured and arranged such that a conduit to be electrically connected to the compressor assembly enters the cover wherein the clip engages the conduit and prevents the egress of the conduit.
Abstract:
A wire separator capable of maintaining wires in a fixed bundle. The wire separator comprises an inner member having a plurality of apertures into which wires may be positioned via a plurality of gaps in the inner member. The wire separator also comprises an outer member capable of attaching to the inner member. Furthermore, the outer member has a slot. When the outer member is in a first position, the slot misaligns with the gaps, thereby maintaining the wires in the inner member and inhibiting wires from inadvertently falling out. In a second position, the slot aligns with at least one of the gaps to thereby facilitate quick removal or insertion of a wire into the wire separator while the other wires remain securely enclosed within the wire separator. Also, the same outer member can attach to different inner members with different numbers of apertures to advantageously reduce costs.
Abstract:
Joint formations that, in joining together joining members employed in a variety of electrical and electronic components, yield sufficiently high joint strength in the direction perpendicular to the plane in which two joining members join, and meanwhile in the direction parallel to the joint plane. Two joining members 11 and 12, each with a plurality of continuous faces as joint faces, are joined to each other by interposing a bonding agent 3 between the joint faces. The difference in coefficient of thermal expansion between the two joining members 11 and 12, and between the joining members 11 and 12 and the bonding agent 3, is 5.0null10null6/null C. or less. The joining members are a metal such as tungsten or CunullW, or a ceramic such as AlN or Si3N4; and glass or a solder material is utilized for the bonding agent.

A weatherproof junction box which may be mounted in non-traditional locations is provided by the present invention. The junction box includes a housing member or splice compartment with at least two threaded openings. The splice compartment is attached to a mounting bracket that is designed to receive lag bolts or straps, which may be used to mount the junction box to a tree, pole, wall or similar structures. The junction box also includes a twist-to-open lockable cover that provides easy access to the interior of the splice compartment, even when the junction box is mounted.
