Title: Cylinder structure for pressure reducing valve
Inventor: YOKOYAMA TAKESHI
IPC: G05D16/16
Filed: 1989-12-15
Abstract: PURPOSE:To improve reliability as a pressure reducing valve by controlling a main valve body by means of the slide of a cylinder and a mainbody inner wall so as to open/close a main valve port even if chattering occurs and a piston and the cylinder are caught. CONSTITUTION:When chattering occurs and the piston 20 and the cylinder 22 are caught, the sliding resistance of both considerably becomes large, it becomes larger than the energizing force of a spring 54 and the cylinder 22 is vertically displaced in the state where the piston 20 and the cylinder 22 are caught. Consequently, the piston 20 energizes the main valve body 18 and the main valve port 14 can be opened and closed in a usual way, whereby it functions as the pressure reducing valve. Then, the cylinder 22 vertically slides in the state where the piston 20 and the cylinder 22 are caught. The upper end surface of the piston is impulsively abutted on the lower end surface of a spacer 27, a piston rod 20b on the projecting part of the main valve body, or the upper end of the cylinder 22 on the lower end of the spacer 27. Consequently, the piston and the cylinder which are inclined and are caught are released. Thus, reliability as the pressure reducing valve improves.

Abstract: PURPOSE:To improve the design by forging a disk stock, and manufacturing the disk stock using the same die more than the prescribed time in a disk for a road wheel to be obtained in the processes of forging and casting. CONSTITUTION:When the disc stock M of aluminum alloy, for example, is placed in a furnace and heated at about 450 deg.c, the first forging of the disk stock is executed by a forging die 3 provided with an upper die 1 and a lower die 2. The disc stock M is formed to the shape of the disk D of the final shape, but the inner material flows on the surface side to form the new surface, and the porosity in the stock which is generated in the casting appears on this surface. Thus, the second forging is executed by the same forging die 3 for the disk stock M. The finish forming of the whole disk stock is executed, and at the same time, the porosity is crushed by the pressure applied on the surface, and the disk D which is surface finished to the excellent condition without porosity is formed.

Abstract: PURPOSE:To achieve the conservation of space and the reduction of cost by performing both of the aeration and sedimentation in a conventional apparatus within one tank by arranging a hollow fiber module consisting of many porous hollow fibers and an sir diffusing pipe in a treatment tank. CONSTITUTION:Raw water such as the waste water of a building is introduced into a treatment tank 2 from a raw water tank 1 through a water supply pump 3 and aerated in the treatment tank 2 by the air sent from an air diffusing pipe 11 through a blower 13. The raw water passed through the slit-like fine pores 19 formed to porous hollow fibers 14 is sent to a predetermined tank as transmitted water through transmitted water pipes 6a, 6b. By this method, the bacteria or algae in the raw water are efficiently removed. Since the hollow fiber module consisting of many porous hollow fibers 14 has an extremely large specific filtering area, the conservation of space can be achieved and the hollow fiber module can be arranged in a reaction tank in an arbitrary shape because of its flexible properties and an exclusive housing becomes unnecessary.
