PURPOSE:To realize a thin type battery without fluid electrolyte, by furnishing a groove route linking to the outside of a battery jar at a part of the jar which consists of thin plastic films housing a set of electrode plates, in order to exhaust gas and prevent an invasion of the outer air. CONSTITUTION:A negative electrode plate 1, a separator 2, and a positive electrode plate 3 are housed in a...

PURPOSE:To control a short circuit generated at the lower part of an electrode plate group, by forming grooves or slits on a glass mat in the vertical direction of electrodes as passages of gas, and contacting these grooves or slits responding to the vertical frames of a positive electrode plate. CONSTITUTION:A positive electrode plate 5 is formed by filling an active substance 4 composed of Pb O2...

A needle of the kind for use in surgery, especially micro-surgery, for stitching human tissue with a suture is characterised by a body portion (1) and a tip (2) which is secured to the body portion. The tip (2) is of a material which is harder than that of the body portion (1) and has a sharp cutting edge. The tip material may be a gem such as a diamond, sapphire or ruby, or an amorphous compound ...

1. High-frequency surgical apparatus with automatic control of the intensity of the electric arcs between the active electrode and the tissue to be out or to be coagulated, wherein, for establishing the size of the arc, an electrical signal dependent thereon is derived via a filter and is fed to a rectifier (7), the output signal (E) from which is fed to a control amplifier (5), in which this outp...

PURPOSE:To permit to replace a former quickly by a method wherein tow kinds or more of formers are attached previously to a former supporting means and the same means is rotated and, thereafter, is positioned when the formers are replaced by different formers. CONSTITUTION:When the kind (diameter) of a former 2 is to be replaced, a supporting frame 7 is elevated after releasing a knock pin for pos...

The invention relates to a safety ski binding have a locking member which is subjected to the action of a mushroom-shaped element mounted in a retaining part. Via a latch, the mushroom-shaped element holds a heel support in the skiing position and releases this, in the event of predetermined vertical and lateral release forces, against the force of a spring. As a result of the invention, the inten...

This toepiece has a baseplate, on which two connecting rods are mounted pivotably by their one ends on axes running at right angles to the baseplate and are connected at their other ends via a footplate, the axes of the connecting rods assigned to the baseplate lying further from the ski tip than the axes of the footplate, and the footplate being held in its central position by at least one spring...

Novel open-cell polymer foams are prepared from foamable polymer compositions comprising (a) an ethylenic ionomer which (1) is crosslinked by metal ions, (2) contains from 85 to 98.5 mol percent of ethylene polymerized therein and (3) has a crystallization initiating temperature, T, in DEG C satisfying the following Formula I: 102 - 3.02 (98.5 - A) > T > 102 - 9.29 (98.5 - A) I wherein A represe...

This device comprises a resilient stress-responsive member interconnecting two conduits which can be respectively coupled to upper and lower portions of the downhole assembly, and are surrounded by a protecting sleeve making up with one of said conduits, the lateral walls of an annular space. Annular elements secured to a first of said lateral walls, and slidable on the second of said lateral wall...

Mechanical working of aluminium or aluminium alloys is carried out in the presence of a water-based cooling lubricant, which has the form of a stable solution and contains as lubricating and corrosion inhibiting agents a combination of (a) a carboxyl compound having a hydrophobic group of 7-14 carbon atoms and (b) a tertiary alkyl alkanol amine having a molecular weight of less than 300. The amoun...

Dispersions of colloidal siliceous particles, preferably silica, may be prepared in organic liquids by means of a synergistic mixture of dispersing agents comprising a phosphorus oxy-acid derivatives and a long-chain amine. Dispersions containing a high weight fraction of siliceous solids are possible having a lower viscosity than is normally achieved.

PURPOSE:To improve the yield of a hybrid integrated circuit having high reliability and high heat resistance, and to reduce cost thereof by aging a chip part on a substrate under clean environment prior to hermetic seal and repairing or exchanging defectives on the basis of electric function inspection. CONSTITUTION:A chip part 4 such as an IC chip is mounted on a die bonding pad 2 on a multilayer...

PURPOSE:To enable repairing to be performed even on trouble by manufacturing a hermetic seal hybrid integrated circuit device and then providing a process in which a welding section with a cap made of a metal is polished and broken mechanically and defective chips are exchanged. CONSTITUTION:Metallic weld rings 3 are fitted to conductor patterns 2 on a multilayer interconnection substrate 1 by adh...
