A resilient mechanism for maintaining the jaw unit of a safety ski binding in the normal boot-retaining position includes two vertical flat faces extending transversely on a stationary jaw-unit support. Two flat cams applied against the flat faces by a single spring consist respectively of a bearing surface of the jaw-unit body and of a small bearing plate carried by a rod on which the jaw-unit bo...

PURPOSE:To always obtain a plasma arc with long length in a stable state by using plasma gas adding hydrogen of a specific ratio to argon and specifying frequency of a plasma current in the nonmobile type plasma working. CONSTITUTION:At the time of performing the nonmobile type plasma working by a plasma device, mixed gas of the hydrogen with the argon is used for the plasma gas and the ratio of t...

PURPOSE:To obtain a superconductive electric wire having a structure in which little strain is produced by mechanical stress by putting plated composite electric wires in a pipe, drawing down the pipe to the desired diameter and subjecting it to diffusion heat treatment. CONSTITUTION:An in situ rod 20 contg. many Nb fibers 21 dispersed and arranged closely in a matrix 22 is prepd. The rod 20 is dr...

PURPOSE:To carry out diameter reduction working and also making concentric with keeping excellent workability even if enlarged in capacity, by manufacturing an in situ rod and then by adding the third element to the above. CONSTITUTION:The in situ rod 1 having a structure in which many pieces of Nb fibers 2 stand close to each other and are dispersedly arranged in a copper-tin alloy matrix 3 is pr...

PURPOSE:To obviate troubles during diameter reduction working, by combining a core body as the third element with an in situ rod and by subjecting the resulting composite body to diameter reduction working prior to diffusion heat treatment in a state where the metallic elements in the in situ rod and the third element are not allowed to react with each other. CONSTITUTION:The in situ rod 1 having ...

A syringe is provided with a helical spring, which furnishes an upper limit to a pressure employed via a plunger to move a fluid or paste through an opening in a syringe. The plunger is maintained in a low compressing state versus the fluid with the helical spring. A toothed rack is attached to the plunger. The toothed rack is engaged by a ratchet forming part of a lever. The lever is hinged on an...

PURPOSE:To inspect a signal of a completed product by applying the signal from an exterior by providing an external terminal wire bonded to an inspecting electrode at a lead frame, and bending the terminal along the side face of the end of a package to remove the terminal to be inspected out of the package without increasing the external configuration. CONSTITUTION:In a dual-in-line type semicondu...

A towel or mat, such as a bar towel, is made from a stitch bonded non-woven fabric which comprises 50% polyester fibres and 50% viscose fibres. The towel or mat is preferably printed with a pattern or design. The fibres may be further bonded at intervals by particles of synthetic resin which may be incorporated in the printing ink used and/or may be sprayed onto the respective surface of the fabri...

In a process for producing tubular shaped fibrous articles of small diameter by heating and cooling a fibrous bundle containing at least 20 weight % of hot-melt-adhesive composite fibers, the improvements comprise using a shaping apparatus including an injecting chamber (1), an injecting hole (2) formed in the wall of the chamber, a fibrous bundle outlet (5) provided with a nozzle of a desired sha...

A device for filtering the lubricant oil used in vacuum pumps, to be directly installed on the pump, for continuous or discontinuous operation, and characterized in that the filter is of the tangential-flow type.

In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement by contacting such face, at a coating station with at least one stream of droplets comprising one or more substances from which said coating is formed there is a problem in forming uniform high quality coatings which are free from structural defects. To help reduce this probl...
