  • Publication number: 20100025166
    Abstract: A brake caliper (10) includes a pair of caliper arms (12) that oppose frictional surfaces (6) formed on respective side faces of a vehicle wheel (5). The caliper arm (12) applies a brake to the vehicle wheel (5) by pressing a brake pad (7) against the frictional surface (6). A pressure chamber (63) delimited by a diaphragm (75) is formed in the caliper arm (12). A plurality of pistons (55) which drive the brake pad (7) in accordance with expansion of the diaphragm (75) corresponding to a supply of compressed air to the pressure chamber (63), and a guide member (65) that guides displacement of the plurality of pistons (55) in a right-angle direction relative to the frictional surface (6) are provided, and therefore the movable brake pad (7) applies an even braking force to the vehicle wheel (5).

  • Patent number: 5424173
    Abstract: A system and method are provided for compensating for proximity effects between selected adjacent portions of pattern elements on an integrated circuit wafer where it is determined by simulation that undesirable resist patterns will result. The subject lithography system includes projecting an electron beam onto the wafer through an aperture plate of pattern elements to obtain the desired beam pattern. An aperture mask includes a plurality of first portions corresponding to first wafer circuit element portions spaced for avoiding proximity effects on the wafer and a plurality of second portions corresponding to second element portions spaced for obtaining proximity effects between elements on the wafer. The plurality of second portions are sized to have an increased adjacent spacing relative to a resultant adjacent spacing of the corresponding second element portions whereby the resultant adjacent spacing of the second element portions on the wafer is selectively reduced by the proximity effects.

  • Patent number: 5334845
    Abstract: In an electron beam exposure method for production very high-integration semiconductor devices and its related apparatus in a conventional method, the exposure is divided into fine divisions and carried out by performing a number of shots. However, by utilizing an aperture stop produced by working a single crystalline silicon thin film finely, exposure of a predetermined range is done by one shot. According to the invention, the exposure can be accomplished by the number of shots which is smaller by about two orders than that of the conventional technique and the throughput can be improved remarkably. Since the shot number does not substantially differ depending on whether patterns are complicated or not, individual steps can be processed within substantially identical time.
