The punch appts. has a planar element of highly conductive material mounted on normal to the direction of movement. A planar coil is fixedly mounted on the frame coaxially with punch element and adjacent to the planar element. A carriage positions a thin sheet of material to be punched in the path of the punch element and moves the sheet in direction transverse to the axis of the punch element. Th...

PURPOSE:To make higher a limit to turning radius by controlling an increase or a decrease in a differential limiting force from the outside on the basis of detected signals of a turning direction and the rotary speed of right and left driving wheels, and prohibiting the function of a driving wheel propulsion control device. CONSTITUTION:A control device 13 judges a turning direction on a steering ...

Rotating cutting tool, in particular a drilling, milling and/or reaming tool, with a tool body having a pronounced longitudinal extension in the direction of the rotational or main axis and made of carbide or mechanically resistant material, which tool body has on its outside at least one groove running preferably at an angle to the axis differing from 0 DEG , in particular roughly helically, and ...

The fleece web (60) to be patterned is guided past a first treatment station (36-38, 64) between a perforated supporting member (40) and a perforated drum casing (30, 33). At the same time, by being subjected to fluid, the fleece web (60) is provided with a first pattern, in that the fibres are ordered by the specific position of the perforation of the member (40) and of the casing (30, 33) in ord...

PURPOSE:To eliminate the boundary of a connecting part and improve connecting strength by a method wherein the connecting part between an end plate and a heat exchanging pipe, which are made of synthetic resin which consists of the same constituent, is dipped into the solution of principal constituent of the same synthetic resin, thereafter, is taken out of the solution and is dried. CONSTITUTION:...

A deactivator for deactivating targets used in electromagnetic article surveillance systems comprises a solid element with a convexly curved outer surface, e.g., a cylinder and a plurality of permanent magnets which form a patter of variously directed magnetic fields is a plane adjacent the surface. The curved surface of the deactivator is rolled over a target to be deactivated. The magnets are al...

PURPOSE:To dry a microcapsule within a short time by simple operation without destructing the same, by successively immersing the microcapsule prepared by a coacervation method in ethanol aqueous solutions from low concn. to high concn. CONSTITUTION:A microcapsule is immersed in about 5% ethanol aqueous solution at first and, on and after, successively immersed ethanol aqueous solutions of which t...

An elongate member, for example, in the form of a flag pole, comprises two components 2, 3 interconnected, with part of one component being inserted into an open mouth defined by the other component. One component carries two bushes 4, 5, each bush defining a plurality of peripheral grooves of different depths. An O-ring is associated with each bush, each O- ring being positioned in a selected gro...
