The actuation control valve V controls to charge and discharge a hydraulic actuator A such as a boom cylinder 22 and travel motors with hydraulic oil from a hydraulic pump P, which is connected through the pump-pressure oil passage 41 to the actuation control valve V The hydraulic actuator A is connected with the actuation control valve V by the connection oil passage 43, and the actuation control valve V is connected to a tank T by the tank oil passage 51, in which the return filter 60 is provided. The part of the tank oil passage 51 downstream with respect to the return filter 60 is connected to the hydraulic pump P by the drain oil passage 53, in which the drain filter 70 is provided.

Abstract: A master device and a slave device are each constituted of a transmitting section; a receiving section; and a control section including a three-dimensional position calculation section for calculating a three-dimensional position of the transmitting section of the counterpart master device or that of the counterpart slave device and an element drive section for driving an MEMS element. First, the master device outputs transmission light having comparatively narrow directivity, and the transmission light is two-dimensionally scanned. Next, the receiving section of the slave device receives that transmission light, calculates the transmission direction of the master device from the position of a spot of transmitted light on a light-detecting element array, and transmits the transmission light in that direction. At this point in time, scanning of the transmission light from the master device is stopped, and subsequently communication is initiated.

Abstract: A switch device in a steering wheel includes a front switch assembly and a back switch. The front switch assembly is provided on a front side of the steering wheel that faces the driver, and rotates integrally with the steering wheel. The back switch is provided on a back side of the steering wheel. The front switch assembly includes at least one front switch. The front switch assembly also includes a circuit board. A front switch light source is provided on the circuit board. The front switch light source illuminates a switch marking provided on the front switch. On the circuit board is also provided a back switch light source for illuminating a switch marking provided on the back switch. Accordingly, a manipulation switch on the steering wheel is reliably illuminated regardless of the rotation angle of the steering wheel.

Abstract: An optical disk apparatus includes a carriage, a plurality of objective lens support portions, and a plurality of magnetic field generating means. The carriage is placed to oppose an optical disk and held to be reciprocally movable between an outer peripheral portion of the optical disk and its central portion. Each of the objective lens support portions has an objective lens elastically supported by an elastic member. The magnetic field generating means move each of the objective lenses in a direction perpendicular to the surface of the optical disk and a radial direction of the optical disk. Some of the magnetic field generating means which are used, in pairs, for the objective lens support portions are shared by the plurality of objective lens support portions.

Abstract: An excitation wavelength sweeping type Raman spectroscopic apparatus including a wavelength variable laser source, a laser beam converging unit for irradiating a laser beam from the laser source onto a specimen, a bandpass filter for selecting a beam of a predetermined wavelength out of Raman scattered light beams emitted from the specimen, and a photodetecting unit for detecting the beam selected by the bandpass filter. In the apparatus, a Raman spectrum of the specimen is measured by sweeping the wavelength of the laser beam.
