IPC: B61F5/00
Filed: 1978-03-08
Abstract: PURPOSE: To provide the subject device wherein the set height of a pneumatic spring is varied at any time in correspondence to the variation in the load of a vehicle, thereby to increase or decrease the load borne by a coil spring and, at the same time, the variation state of the supporting height of the pneumatic spring is varied curvilinearly.  
     CONSTITUTION: The spring unit is constituted by a conical coil spring or an oil damper chamber 51 is formed into a conical shape where the section of the chamber is constructed toward the compressed air chamber 52 side, and, at the same time, the inner peripheral part of a rolling seal 58 arranged within the oil damper chamber 51 is fastened to a piston 54' and its outer peripheral part is fastened to the inner periphery of the cylinder main body, thereby to lower or raise the pivoting fulcrum in proportion non-linearly to the pressure within the pneumatic spring 3. According to the above described construction, displacements in proportional to the load pressure can be afforded to both the pneumatic spring and the coil spring, and the entire spring can be utilized effectively and the variation state of the height of spring can be made non-linearly. Therefore, unreasonable burdens are not borne to the spring unit itself and hence the life of the spring unit can be prolonged.

Title: Embossed spacer film for film carrier use
Inventor: OKABE NORIO
IPC: H01L21/60
Filed: 1989-02-06
Abstract: PURPOSE:To prevent deformation of sprocket holes and deterioration of flatness of a film carrier by a method wherein the top of a protrusion is formed in a flat and nearly rectangular shape and its length is made longer than the sprocket hole in the film carrier. CONSTITUTION:Protrusions 10 having flat and nearly rectangular top parts 10a are formed, by using a hot press, alternately on both faces of a polyethylene terephthalate film along both end parts of the film; an embossed spacer film 1 for film carrier use is formed. During this process, a length L at each top part 10a is made larger than a length (l) of the sprocket hole 3a in a film carrier 3. When a shape of each embossed protrusion at the top part is formed in a flat and nearly rectangular shape, a stress is not concentrated and deterioration of flatness is prevented; in addition, when the size of the top parts is made larger than that of the sprocket holes, it is possible to eliminate deformation of the sprocket holes, caused when the protrusions fall into the sprocket holes.
