Title: Laser working method
Inventor: MIURA HIROSHI
IPC: B23K26/382
Filed: 1981-06-11
Abstract: PURPOSE:To reduce an entire working time in the stage of working points at plural places by moving materials to be worked sequentially with a laser at the lowred speed to the extent of obviating deterioration in working characteristics without stopping the materials to be worked during working. CONSTITUTION:When plural working points are going to pass through a laser condensing spot. a locus 3 wherein the moving time including acceleration control is shortest is beforehand determined. The working points thereon are defined sequentially as 1, 2... and the points just before the respective working points where a moving table is decelerated are defined as 1l, 2l.... The respective coordinates are determined as shown in the figure. The moving speed of the materials to be worked on the working table is made a function of positions. In the position (il), said speed is decelerated, and in the position (i), the speed is lowest, and at this point, the laser is irradiated. This min speed (v) can be set by the equation I if the irradiation time is defined as (t), the diameter of punching with a laser or the diameter of weld nugget as (d), and the permissible deformation of the working diameter is <=10%. The distance Li between the points (il) and (i) follows approximately the equation II, but it is justified if it is the distance required for deceleration to the (v) from the moving speed.

Title: Liquid pressure booster
Inventor: SATO TORU
IPC: B60T13/12
Filed: 1990-04-05
Abstract: PURPOSE:To obviate the provision of air flow holes opened constantly as in the prior art so as to impede the immersion of water or the like into a guard member by providing a guard member with a check valve to perform the inflow/ outflow of air. CONSTITUTION:When an input shaft 5 and an operating rod 9 move forward during braking operation, the volume of a guard member 10 is contracted to increase its inner pressure. A lip 10d at the front is thereby deformed elastically and separated from the outer peripheral surface of the groove 2a of a housing 2. As a result, an air flow passage is formed between the lip 10d and the outer peripheral surface of the groove 2a, so that air in the guard member 10 flows outside. When the brake is released, the input shaft 5 and operating rod 7 move backward. In association with this, a lip 10e at the rear is elastically deformed and separated from the outer peripheral surface of a groove 9a', and an air flow passage is formed between them, so that atmospheric air flows into the guard member 10.
