    • A disk brake assembly has a piston retraction structure which can keep the space between the pad and the disk constant while the brake is not being applied by varying the distance the piston is retracted with the fluid pressure applied to the disk brake. The piston retraction structure has a piston seal fitted in a seal groove formed in the inner surface of a cylinder of a caliper. When a piston is advanced under fluid pressure, the piston seal is pulled by the piston and deformed until it fills up the gap defined by a chamfer formed along the edge of the seal groove. When the fluid pressure is removed thereafter, the piston is retracted by the resilient restoring force of the deformed piston seal. The piston seal is made of a rubber having a hardness of 80 IRH or more. In another arrangement, the piston seal has its outer-diameter portion fitted in the seal groove with a zero gap or with an interference. By further adjusting the size of the chamfer, it is possible to vary the distance the piston is retracted with the fluid pressure in an ideal manner.
    • 盘式制动器组件具有活塞缩回结构,其可以通过改变活塞在施加到盘式制动器的流体压力下缩回的距离而使制动器不被施加时保持垫和盘之间的空间恒定。 活塞回缩结构具有装配在形成在卡钳的圆筒的内表面中的密封槽中的活塞密封件。 当活塞在流体压力下前进时,活塞密封件被活塞拉动并变形,直到其填充由沿着密封槽边缘形成的倒角限定的间隙。 当此后除去流体压力时,通过变形的活塞密封件的弹性恢复力使活塞缩回。 活塞密封件由硬度为80IRH以上的橡胶制成。 在另一种布置中,活塞密封件的外径部分装配在密封槽中,零间隙或干涉。 通过进一步调整倒角的尺寸,可以以理想的方式改变活塞与流体压力缩回的距离。

    • A projection type image display apparatus of the invention has a lamp mounting mechanism, which has an aluminum lamp holder (166) intervening between the lamp (16) and the resin lamp holder (167) and has a section exposed out of the resin lamp holder (167). The lamp (16) is securely fixed in position on the aluminum lamp holder (166) by mounting the lamp (16) on the aluminum lamp holder (166) from above and then folding the top section (166d) towards the top end of the lamp (16). This lamp mounting mechanism can suppress the temperature of the resin lamp holder without providing a cooling fan with a large amount of power and suppress fan noise, thereby simultaneously enabling uprating of the power of the lamp and downsizing of the image display apparatus.
    • 本发明的投影型图像显示装置具有灯安装机构,该灯安装机构具有介于灯(16)与树脂灯座(167)之间的铝灯座(166),并且具有从树脂灯座 (167)。 通过从上方将灯(16)安装在铝灯座(166)上,然后将顶部部分(166d)朝着顶部部分(166d)折叠,将灯(16)牢固地固定在铝灯座(166)上的适当位置 灯(16)。 该灯安装机构能够在不设置大量功率的冷却风扇的情况下抑制树脂灯座的温度,并且抑制风扇噪声,从而同时实现灯的功率上升和图像显示装置的小型化。
