Abstract: To reduce the bending stress acting on a bracket in a chain tensioner or chain guide when a chain is traveling, a bracket of a chain tensioner is provided with a laterally symmetrical transverse-sectional shape by bending one thin sheet of sheet metal having a thickness of preferably no more than 1 mm. The transverse-sectional shape is configured by a shoe mounting part and an upright wall part which projects to the back surface thereof, the structure of each of these comprising two layers of sheet metal, and the two sheets of sheet metal are fixedly attached by spot welding or the like, for example, at the upright wall part. The transverse-sectional shape includes substantially an “I” shape, “T” shape or triangular shape.

Abstract: A toroidal type continuously variable transmission whose gear ratio is varied by changing the position of a trunnion is provided with double-slider valves driven by stepping motors and linear solenoid valves. The gear ratio control is performed by controlling position of the double-slider valves when the vehicle travels at speeds higher than a specified speed or by controlling directly line and relief pressures applied to the trunnion through the solenoid valves.

Abstract: A film mask is abutted to the object at the one side thereof then a fluid is introduced at an other side of the film mask so as to press the film mask to be placed in contact with the object.

Abstract: A connector apparatus to be connected to an IC pack comprises housing means for receiving and holding the IC pack inserted thereto, connector means for connecting electrically to the inserted IC pack, ejecting means for ejecting the inserted IC pack from the connector means having at least two ejecting arms having a U-shaped cross section, two opposing sections of the ejecting arm sandwiching the housing means, and the other section perpendicular to the opposing sections being arranged to contact with the front end of the IC pack, and means for activating the ejecting means so as to eject the IC pack from the connector means by pulling out with the ejecting arms kept in contact with the front end of the IC pack.

Abstract: A connector apparatus for making a connection between a signal line and an external circuit is disclosed which comprises a connector body having first and second pairs of terminals, each pair of terminals comprising a pair of contact pins, a first connector element having two terminals each attachable to and detachable from one end of each of the pair of contact pins of the first pair of terminals, the two terminals being connected to the signal line, a second connector element having two terminals each attachable to and detachable from one end of each of the pair of contact pins of the second pair of terminals, and terminating resistor connected between the two terminals in the second connector element, in which the other end of each contact pin of the first and second pairs of terminals is used as an external circuit connector terminal.

Abstract: A connector apparatus comprises a header connector, into which an IC pack is loaded and from which it is unloaded, and an ejector unit detachably mounted on the header connector. The header connector includes a locking lever having a protrusion which is adapted to engage a locking notch in the surface of the IC pack, when the IC pack is loaded. The ejector unit includes a base attached to one surface of the heater connector, a push lever attached to one side portion of the base, so as to be movable in the loading or unloading direction of the IC pack, an unlocking lever formed integrally on the push lever and adapted to engage the locking lever, when the push lever moves in the pack-loading direction, and an eject member movably mounted on the base and having an eject portion adapted to move in the pack-unloading direction as the push lever moves in the pack-loading direction.

Abstract: A connector device is disclosed which can branch or terminate signal lines for making a mutual connection among a plurality of units. The connector device includes switches between signal line connection terminals so that the connector may serve as both a branch connector and a strap connector. A hook is provided on a body case of the connector device and usable in interlock with the switch. A groove engageable with the hook is formed on a connector element case for external circuit connection so that through the selective engagement of the hook with the groove the element case is prevented from being inadvertently detached from the body case. During the detachment of the element case, the contact pin is placed in a short-circuited state at all times. A terminating connector device is also disclosed which is comprised of a combination of a connector body with first and second connector elements. The connector body includes first and second pairs of terminal.

Abstract: A connector device comprises a plug pin and a receptacle for receiving the plug pin therein. The receptacle is bent into a substantially rectangular parallelepiped configuration such that a pair of parallel elastic contact sections are formed at one side of a pair of opposite sides of the rectangular parallelepiped. The plug pin is also of a substantially rectangular configuration in cross section to permit it to be elastically sandwiched between the aforementioned opposite sides of the receptacle. The plug pin is so formed as to have arcuate side edges at its side face which is contacted by the pair of elastic contact sections.

Abstract: A receptacle is disclosed which includes first and second rectangular frames each having a rectangular opening, so that a plug pin can be detachably inserted into the receptacle through the first rectangular frame. The first rectangular frame is connected to the second rectangular frame through a pair of leaf spring pieces. The pair of leaf spring pieces are inwardly curved toward each other so that the plug pin, when inserted into the receptacle, is electrically connected to the receptacle, and said plug pin is elastically retained between the inwardly curved portions of the leaf spring pieces.

Abstract: An electric connector comprises a female contact and a thermoplastic housing. The contact has upper and lower click pieces. The housing has a contact receiving hollow open on its rear side. A pair of slits, spaced apart from each other, are cut in the top of the housing. One end of each slit reaches an opening of the hollow. A projection for retaining the upper click piece is formed on the lower surface of that portion of the top which is defined by the two slits. A step for retaining the lower click piece is cut in the inner surface of the bottom of the housing and faces the projection.

Abstract: A railroad car wheel is designed to have an amount of displacement of 40 mm or larger, this amount being the amount of displacement of a rim portion relative to a boss portion of the wheel which is the distance between two lines perpendicular to the axis of the wheel, one from the midpoint of the thickness of a plate portion adjacent to ends of curves of the rim fillets and the other from the midpoint of thickness of the plate portion adjacent to ends of curves of the boss fillets.
