Title: Optical fiber splicer
Inventor: HATSUTORI KATSUJI
IPC: G02B6/32
Filed: 1978-09-01
Abstract: PURPOSE:To obtain an optical fiber splicer not permitting the reflected light to re- enter the own side, by using a self-focusing type lens with inclined spliced surface. CONSTITUTION:Opposing optical fibers 1, 2 are connected with self-focusing type lenses 3, 4 of which periodic length becomes 1/4 along the lens central axis by means of a sleeve 7. Lens end faces 8, 9 are so formed that the end face normal may be inclined with respect to the optical axis by angle alpha. This angle varies with the core diameter of the fiber and lens length, but is determined so that the reflected light may not return to the fiber. For example, when the lens length is 2mm and core diameter is 100mu, the end face normal of the lens should be inclined with respect to the lens axis by an angle of about 3 deg..

Title: Buffer device for unloading impact of press machine
Inventor: SODA CHIYOUICHIROU
IPC: B21J13/00
Filed: 1980-08-06
Abstract: PURPOSE: To provide a buffer device for unloading impact which reduces noises risen at press working by controlling a load, taking with break, through a composition utilizing a phenomenon, wherein, an oil of high viscosity in a sliding surface affects a resisting force proportional to the sliding speed on the sliding of both members.  
     CONSTITUTION: In a press machine provided with said buffer device, a height of a stopper 4 is adjusted in accordance with a thickness and a material of a plate to be worked for cutting, or punching or the like. A press working is conducted by setting an outer cylinder 6 so as to collide with the stopper 4 as just before the plate breaks. Thereby, when the outer cylinder 6 collides with the stopper, though it is sliding on a post 5 against a resisting force generated by an oil of high viscosity and an acting force of a spring 9, the resisting force generated by the oil of high viscosity increases rapidly in proportion to the sliding speed. Thus, when generation of an unloading impact follows the break of the plate material, a large resisting force is generated on the sliding of a large speed between the outer cylinder 6 and the post 5, that is, a buffering action is generated on the unloading impact, and noises risen from the press machine is suppressed effectively.
