PURPOSE:To produce excellent operating performance and operation feeling during both acceleration and deceleration, by a method wherein a step changing rate B during acceleration is set to a different value from that of a step changing rate set during deceleration. CONSTITUTION:In order to insure a high output shaft torque during acceleration, a step changing rate B is set to a high value B1, and ...

Process for the production of miniature piezoelectric devices using machining by laser and devices obtained by this process. The piezoelectric material formed by lithium niobate or lithium tantalate is cut by means of the laser. Application to the production or resonators and filters, which can be used in electronics.

This invention is a method of making negative battery plates in a continuous process, in which a skeletal grid is cast continuously to have the structure of a number of plate grids side by side and longitudinally integrally connected together in the casting. After casting the skeletal grid is pasted, tissues are applied on either side, and then the grid is cut by slitting and transversely to separ...

The compressed-air tubing (5) leading to the splicing chamber (1) of the yarn splicing device is provided with a combined dosing and atomizing valve (7) through which the splicing air passes and which can be actuated by the splicing air injected; thus liquid is applied to the splice. The dosing and atomizing valve (7) has a dosing chamber (22) which is connected alternately to a container of liqui...

An apparatus for partial dehydration of a sludge in the centrifugal field of a centrifuge wherein the residual moisture of the sludge is substantially reduced with a comparatively low compression of the sludge, and the non-effective cone length of the centrifuge is reduced without shortening the sludge dwell time. The invention includes an arrangement of agitator elements within the centrifugal dr...

A closure device for fluid-tight closure of an opening of a fluid container. The device comprises a casing part (1) and a cap part (2). These parts are injection molded from different plastic materials, preferably from PVC and polypropylene, respectively, one partially against the other. A tubular portion (12) of the cap part (2) intrudes sealingly into a substantially cylindrical hollow space bet...

An integral body tissue replacement product constituted by an at least partially degradable, flexible material comprising a polymer matrix having a porous structure, characterized in that the rate of degradation of the polymer of the matrix varies with the distance from the exposed surface or surfaces of the product; and a method of producing such product.

In detection of a defect in a part of an object having a surface which is substantially a surface of revolution, the surface of the inspected part is illuminated by light rays which are emitted through an annular portion coaxially disposed with the surface of the inspected part, and light rays reflected at the surface of the inspected part are received to form an image of the inspected part. The i...
