Abstract: No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).

Abstract: A measuring device (200) is a device disposed in a mobile body, and includes a measurement unit (202) that scans an object by emitting electromagnetic waves. The measurement unit (202) is controlled by a measurement unit control device (203) including a control unit (204). The control unit (204) sets a scanning range of the measurement unit (202) using information on a position that is a predetermined distance ahead. Specifically, the control unit (204) determines a position that is a predetermined distance ahead of the current position of the mobile body (240), on a predicted course of the mobile body (240). Further, the control unit (204) uses information on the position that is a predetermined distance ahead to set the scanning range of the measurement unit (202).

Abstract: A measuring device (200) includes a measuring unit (202) and a control unit (204). The measuring unit (202) performs a scan of an object by emitting an electromagnetic wave and receiving the electromagnetic wave reflected by the object. The scan is performed while changing an emission direction of the electromagnetic wave in two dimensions, in a height direction and in a lateral direction. The control unit (204) determines a scan range in a subsequent scan by the measuring unit (202) based on a received signal by the measuring unit (202) in the scan of the measuring unit (202).

Abstract: Provided is an actuator for use in a pickup device, which can improve the quality of the pickup device by reducing a lens distortion even when the frequency of an electromagnetic drive rises beyond a servo band and causes resonance of a lens holder. An adhesive layer (11) is formed between an outer peripheral portion (6A) of an objective lens (6) and a lens holder (4). This adhesive layer (11) has a sufficient thickness dimension enough to absorb deformation of the lens holder (4) even when the lens holder (4) is deformed due to resonance. Even when the frequency at which an electromagnetic drive (9) operates rises beyond the servo band and causes resonance of the lens holder (4), the adhesive layer (11) functions as a buffer so that deformation of the lens holder (4) is less transmitted to the objective lens (6).

Abstract: A magnet used for an actuator of an optical pickup has a magnetization pattern has two different pole areas adjacent with each other. At a corner part defined by the boundary line of the two pole areas, the pole area inside the corner part has a projection area, projecting in the direction of the pole area outside the corner part. Owing to the existence of the projection area, insufficiency of the magnetic flux density at the corner part particularly close to the vertex can be improved so that a desirable magnetic field can be provided to the printed coil substrate disposed in the vicinity of the magnet.

Abstract: The pickup device is used in a drive device of an optical disc and is opposed to the optical disc to irradiate a light beam from a light source onto an information recording surface of the optical disc. The pickup device has the actuator including the objective lens for condensing a light beam on the information recording surface of the optical disc, and irradiation of a light beam on the optical disc is controlled by moving the objective lens. Further, the pickup device has the optical system for directing a light beam, which is emitted from the light source, to a position below the objective lens. The optical system is placed at the same height level as the actuator. Therefore, as compared with the case where the optical system is provided below the actuator, the whole pickup can be smaller in thickness, and it is possible to provide a pickup device suitable for a thin drive device.

Abstract: The actuator is used in a pickup device for a drive device of an optical disc. The actuator is positioned opposing to the optical disc to irradiates a light beam from a light source to an information recording surface of the optical disc. The objective lens is fixed at on the lens holder forming the actuator at a position closer to one end thereof. One coil substrate is fixed on one side face of the lens holder in a range from the one end of the lens holder to a center portion of the lens holder, and the other coil substrate is fixed on the other side face of the lens holder in a range from the other end of the lens holder to the center portion of the lens holder. Therefore, near the end of the lens holder on the objective lens side, the coil substrate is not attached to one side of the lens holder, providing a space below the objective lens. By arranging an optical system to guide the light beam to the objective lens via the space, the optical system can be arranged at the same height level as the actuator.

Abstract: A coil substrate used for a lens driving apparatus is provided in a drive device for an optical disc. The coil substrate includes a tracking coil and a pair of focus coils disposed on a substantially rectangular substrate. The pair of the focus coils is disposed on the both sides of the tracking coil in the direction of the longer side of the substrate. The tracking coil and the focus coils may be substantially aligned in the direction of the longer side of the substrate, or may have the substantially equal lengths in the direction of the shorter side of the substrate. Thereby, the lengths of the coils in the direction of shorter side of the coil substrate can be made smaller. Thus, the coil substrate and the magnet can be reduced in size, and the miniaturization of the entire lens driving apparatus can be achieved.
