    摘要: A projection display device is provided with a cooling section which supplies air drawn from an outside of the projection display device to a member to be cooled which is disposed in a main body cabinet to cool the member to be cooled; a filter section which removes unwanted matters from air drawn to the cooling section; and a filter housing portion which detachably houses the filter section therein. In this arrangement, the main body cabinet is formed with an opening which passes the filter section therethrough in detaching the filter section from the filter housing portion. Further, the filter housing portion is formed with a first space on an air flow-in side of the filter section. Furthermore, the opening has at least such a size that the first space communicates with the outside through the opening.

    摘要: An image display apparatus has a first exhaust fan (13) for mainly exhausting air from a light source unit (9) and discharging the air to the outside of the image display apparatus and a second exhaust fan (14) for mainly exhausting air from a power supply unit (11) and discharging the air to the outside of said image display apparatus. The inspiration face of the second exhaust fan is arranged to partly overlap the expiration face of the first exhaust fan. Accordingly, the internal temperature of the image display apparatus, and hence the temperature of the exhaust air, can be efficiently reduced, and at the same time fan noise of the fans can be reduced. As a result, uprating of power of the light source unit and downsizing of an image display apparatus can be simultaneously achieved.

    摘要: A grinding wheel formed on an outer peripheral surface with a grinding surface is attached to a grinding wheel spindle supported by axial active magnetic bearings and radial active magnetic bearings in a noncontact manner axially and radially and rotated by an electric motor. A casing is axially positioned and then is radially moved and a ground part of a workpiece is ground. Before the casing moves radially and the grinding wheel comes in contact with the workpiece, the stiffness value of the radial magnetic bearings is set to an initialization value lower than a value at the usual grinding time and after the grinding surface of the grinding wheel comes in contact with the workpiece, the stiffness value of the radial magnetic bearings is set to a value higher than the initialization value for grinding the workpiece.

    摘要: A projection type image display apparatus of the invention is equipped with a lamp cooling mechanism, which has a duct (121) for guiding the air sent from an air intake fan (12) in the forward direction from a position lateral to a lamp (16). The duct (121) has a curved wall (122) for directing the air in the duct (121) to the air intake port (164) formed near the open end of the lamp (16). The lamp cooling mechanism has a further guide plate (123) for spreading the air stream directed by the curved section (122) over the region from the tip (161b) to the luminous section (161a) of the lamp (16). As a consequence, relevant sections of the lamp (16) can be efficiently cooled, thereby simultaneously enabling uprating of power of the light source unit and downsizing and lightening of the image display apparatus without supplying the fan (12) with a large amount of power.

    摘要: An improved disk brake which provides both low dragging torque and good pedal feeling even on ABS-equipped vehicles with which the working fluid pressure is around or over 140 kgf/cm.sup.2. The disk brake has a piston seal fitted in a groove formed in the cylinder. The piston seal is deformed when the brake piston is advanced by fluid pressure to press the pad and retracts the piston by its spring-back force when the fluid pressure is released. The width W of chamfer provided at edge of the seal groove is set to 1.0 mm or over and the hardness of the piston seal is set to 75.degree. IRHD or over.
