Abstract: A hoist and traction machine having a load sheave, a driving shaft and a driving member which is screw-threadedly engageable with the driving shaft. An operating handle 16 has an inner plate 16a and a brake cover 13a to cover a mechanical brake. The inner plate and the brake cover both have apertures of about the same size through which passes a portion of the driving member. A sleeve 102 which is separate from the brake cover and the operating lever is received in the apertures and held in place by a flange and a retaining ring so as to facilitate easy assembly.

Abstract: A hoist and traction machine having a free rotation control device/apparatus for selectively controlling the mechanical brake to be inoperative and for maintaining the inoperative mode of the mechanical brake, so as to control the free rotation of the load sheave. The free rotation control device is designed such that improved free rotation control operation can be provided, and the range of the pulling force for the chain can be enlarged in the controlled free rotation of the load sheave; thus, allowing the chain to be pulled quicker, while requiring little operating skill. Further, free rotation operation is not provided when the load sheave (and thus the driving shaft) is subjected to a large load acting in the direction of hoisting down the load, thus achieving highly improved safety.

Abstract: A mechanical brake for a hoist and traction machine, which is provided with brake releasing force control layers at braking surfaces of a driving member opposite to lining plates. Each of the brake releasing force control layers comprising a heat-treated plating layer made of nickel phosphate, nickel chromium or chromium, so that the surface condition of each braking surface of the driving member can be controlled and the surface hardness can be controlled, whereby an initial force for the brake releasing during the lowering of a load or the releasing traction of a load is adapted to be lower.

Abstract: A lever type traction machine including a pair of chain holders for holding a chain entering, between side plates, towards the load sheave. Each of the chain holders is provided with a chain-swelling (slacking) restraint portion for preventing the drain from slacking at the rear of the chain holders. The machine is especially advantageous in that the chain will not become entangled or slackened, even if the traction machine is operated up-side down or on its side.

Abstract: A hoist and traction machine having a mechanical brake, in which an operating handle is non-rotatably and axially movably interposed between a stopper provided at an axial end of a driving shaft and a driving member screwable with the driving shaft. Between the operating handle and the stopper is provided a regulation unit for regulating a relative rotation range of the driving member with respect to the driving shaft so as to enable release of the regulation by moving the handle away from the driving member, so that the driving member is moved away from a driven member by of moving the operating handle from the driving member to be normally rotated in a free-rotation operation mode whereby the braking action of the mechanical brake by a braking ratchet wheel and braking plates is released to control the free rotation of the driving shaft and the elastic biasing member biases it to maintain the state of free rotation control.

Abstract: A via connection and method for making the same for integrated circuits having multiple layers of electrically conductive interconnect lines separated by an insulative layer. The via connection is characterized by a very thin layer of high resistivity material lining the via hole in conductive contact with interconnect lines in two layers. The resistivity of the thin layer material is in a range from about 10 to about 50 times the interconnect line resistivities and generally has a thickness of less than 100 nanometers. The thin layer assures more uniform current flow in the via connection thereby preventing electromigration, with reduced peak local current density by causing current to swing more widely around the corner at the interface between the interconnect lines at the via.
