Abstract: A reflective mask blank includes a substrate; a multilayer reflective film that reflects EUV light; a protection film that protects the multilayer reflective film; and a phase shift film that shifts a phase of the EUV light, the substrate, the multilayer reflective film, the protection film, and the phase shift film being arranged in this order. The phase shift film contains at least one first element X1 selected from the first group consisting of ruthenium (Ru), iridium (Ir), platinum (Pt), palladium (Pd), and gold (Au), and at least one second element X2 selected from the second group consisting of oxygen (O), boron (B), carbon (C), and nitrogen (N). In the phase shift film, a chemical shift of a peak of 3d5/2 or a peak of 4f7/2 of the first element X1 observed by X-ray electron spectroscopy is less than 0.3 eV.

Abstract: In an on-vehicle display device, projection light output from a projecting unit is reflected on an intermediate mirror and is further reflected on a directional mirror. The reflected light is directed to a windshield glass as directed reflected light. In an adjustment operation, the directional mirror is rotated around tilting fulcrum parts by a driving unit to adjust the height of a virtual image formed in front of the windshield glass. In a retracting operation, the lower end of the directional mirror is largely moved forward by the driving unit, rotating the directional mirror with an abutting point between the directional mirror and the upper support acting as a fulcrum. This prevents external light (sunlight) from adversely affecting the projecting unit.

Abstract: A plunger is formed of a soft magnetic material to have one end connected a regulation pin. A permanent magnet is affixed to a stationary portion to attract the plunger in a retreated direction. A coil generates a magnetic flux in an opposite direction of the permanent magnet to reduce a magneto attraction force, which attracts the plunger. A spring biases the regulation pin in an advanced direction. The spring applies a biasing force to the regulation pin to move the regulation pin in the advanced direction when electricity is supplied to the coil to reduce the magneto attraction force of the permanent magnet. A molded portion defines a magnet accommodation hole and a cover member covers the permanent magnet housed in the magnet accommodation hole. A magnetism detection unit is disposed on an opposite side of an inner surface of the cover from the permanent magnet.

Abstract: In a disk drive device, a guide section is formed to protrude from the front surface of a guide top and face a front panel of a frame member with a detection pin therebetween. The guide section forms an inclined side that faces a free end of the detection pin with a gap therebetween. If a disk is shifted from the middle of a disk insertion slot in the right-left direction and is inserted into the disk insertion slot, the detection pin is flexibly deformed by a disk insertion force and is brought into pressure contact with the inclined side. A component force is exerted on the detection pin in a direction in which the detection pin is moved away from the middle of the disk insertion slot in the width direction. The component force smoothly rotates a detection lever from an initial position to an operating position.

Each adapter has a reception unit which receives the transmitted sync transmission frame, and a playback control unit which extracts data corresponding to the channel to be played back by the adapter from the sync transmission frame, and controls the playback timing of the data based on control information corresponding to the data.

Abstract: A springless check valve enables flow of hydraulic fluid from a supply port toward a corresponding one of an advancing port and a retarding port in a connection passage upon lifting of a valve member from a valve seat and limits flow of the hydraulic fluid from the corresponding one of the advancing port and the retarding port toward the supply port upon seating of the valve member against the valve seat. In a synchronously rotatable member, a drain passage is circumferentially displaced from the drain port, and an advancing passage is placed at a corresponding circumferential position, which coincides with a circumferential position of the advancing port. Furthermore, a retarding passage is placed at a corresponding circumferential position, which coincides with a circumferential position of the retarding port.

Abstract: When a normal disk having the diameter of 12 cm is inserted into the disk device, first and second optical detecting elements detect the insertion, and transitions to a first detection state, which initiates transfer operation of first and second transfer rollers. If the disk is further moved to an inner portion of the device, thus pressing first and second detecting pins, first and second detecting switches are turned OFF, and the detecting elements enter a second detection state. Before the transition from the first detection state to the second detection state occurs, a rotating speed of the first and second transfer rollers is set low. After transition to the second detection state, the rotating speed is increased. As a result, a card or other such foreign objects can be removed and a monitoring period can be increased until detection of a normal disk is detected.
