Title: Piston assembling device for disk brake
Inventor: AIKAWA KAZUHITO
IPC: F16D65/56
Filed: 1983-09-20
Abstract: PURPOSE:To automatically assemble a piston easily by allowing a rotary shaft and a piston to make free engagement with/disengagement from each other through a clutch mechanism and pressing a push rod inserted in the center of the rotary shaft by means of a pushing mechanism. CONSTITUTION:A caliper 1 is set to a piston assembling device and a piston 13 with its adjuster nut 15 incorporated therein is placed by the port of a cylinder bore 3 and moved downward by turning a rotary shaft 21 counterclockwise by a motor 33 until the head 27 of a push rod 28 comes in contact with the bottom of the piston. Then the piston 13 comes on the same axial level with a push rod 8, even though the piston 13 is titled, and is turned counterclockwise with a claw 26 engaged in a dent 20 so as to prevent screws 9, 16 from scraping while engaged. And then, the piston is moved downward, while turning clockwise, to get screwed and after creaking is eliminated by turning counterclockwise upwardly once again, assembling is done by resuming the counterclockwise turning downwardly. Thus, the piston can be automatically assembled easily in the cylinder bore of the caliper.

IPC: H01L21/203
Filed: 1993-07-14
Abstract: PURPOSE:To control the crystal growth rate or the crystal composition by interposing more than one shielding board, each having a plurality of openings, between a molecular beam source and a substrate and then varying the relative position of the shielding boards thereby regulating the intensity of molecular beam. CONSTITUTION:An electron beam attenuator is constructed by superposing two shielding boards 1, 2 of diameter D, each having a plurality of small holes 3, at an interval T. The shielding boards 1, 2 are superposed while aligning the position of the small hole 3. The intensity of molecular beam is maximized under that state. When the relative position of the shielding boards 1, 2 is shifted by a distance (d), substantial opening area of each small hole 3 decreases to D-d. Consequently, the transmittance of molecular beam decreases by a factor of (D-d)/D. When the displacement (d) is varied from O to D, the intensity of molecular beam can be controlled continuously from O to maximum level.
