IPC: B60J1/17
Filed: 1991-05-14
Abstract: PURPOSE:To prevent a push-pull cable disposed inside a guide pipe to be movable axially for moving window glass up and down from increasing an operation force for a steering wheel by a push-pull cable by a slide resistance generated at a bent part of the guide pipe. CONSTITUTION:A housing 12 is disposed at a bent part of a guide pipe 14 for containing a worm wheel 36 freely rotatably. A push-pull cable 18 disposed axially movably in the guide pipe is wound around the worm wheel 36 to be engaged. A spiral spring 42 is then disposed in the worm wheel to give a rotary force in the direction of an arrow A. By rotating a steering wheel clockwise, to move the push-pull cable 18 in the direction of an arrow B, the worm wheel 36 engaged with the push-pull cable is rotated, and a slide resistance at the bent part of the guide pipe 14 is reduced. Because the worm wheel 36 is given the rotary force in the direction of the arrow A by the spiral spring 42, an operation force for the steering wheel for moving the window glass up can be reduced.

Title: Multilayered thin metallic film
Inventor: TAKAGI HIROSHI
IPC: C23C14/02
Filed: 1982-06-25
Abstract: PURPOSE:To provide multilayered thin metallic films which improve the strength of a thin film or plate of a metal or semiconductor, by laminating thin metallic films in multiple layers on the surface of said thin film or plate. CONSTITUTION:Thin films 1, 2, 3 of dissimilar metals are laminated successively through thin film interfaces 4, 5 on the above-described surface by any of vacuum deposition, CVD and ion sputtering methods, whereby multlayered thin metallic films are formed. The 6 indicated as T-shaped marks of approximately equal intervals at the interfaces 4, 5 is the misfit dislocation formed so as to reduce the dissidence of the lattice constants of a set of thin films 1, 2 and 2, 3 sandwiching the interfaces 4, 5. Such multilayered thin metallic films are formed with the dislocation of a high density in the films of the films 1, 2, 3 and are therefore higher in strength as compared to bulk material or the like. The combination of the metallic materials wherein the difference in lattice constant is within 15%, the binding force of the interface is strong and the thicknesses of the respective layers are formed within several hundred atom layers is most preferable as the combination of the metallic materials constituting the multilayered thin metallic films, and about 1/100 of the ideal strength can be produced. There is, for example, a combination of a thin Cu film and a thin Ni film as such combination.

Title: Electric discharge machine
Inventor: FUTAMURA SHOJI
IPC: B23H7/00
Filed: 1986-05-14
Abstract: PURPOSE:To keep off any nondesirous deformation in a main structural body and make the extent of machining accuracy improvable as well as to prevent a discharge waveform from dulling and make machining performance improvable, by forming the main structural body with ceramics of a nonmagnetic material. CONSTITUTION:A bed 1, a column 2, an upper arm 3 and a lower arm 4, constituting a main structural body, are all formed with ceramics. Thus, the main structural body is formed by the ceramics, whereby any deformation in it is preventable from occurring. That is to say, because of a nonmagnetic material, a vortex loss due to a discharge current can be brought to nothing. And, since a coefficient of thermal expansion is very small, various thermal effects such as a variation in room temperature, a temperature rise in a dielectric fluid generated heat in electric parts, etc., are preventable. In addition, there is no occurrence of secular distortion as in a casting or a weldment. Moreover, since the main structural body is constituted of the ceramics, any dullness in a discharge waveform is preventable, thus machining performance is improvable.
