  • Patent number: 11143327
    Abstract: A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.

  • Patent number: 11119315
    Abstract: A small-sized information display apparatus capable of displaying, as virtual images, different pieces of video image information at different positions in a wide area of a windshield. An embodiment has a virtual image optical system in which a flat display forming video image information is arranged, and that includes a projected member for causing virtual images to be displayed at a plurality of positions ahead of a vehicle by reflecting a video image on the flat display, thereby forming the virtual images at the plurality of positions so as to correspond to a viewpoint position of a driver. The virtual image optical system is arranged so that video image light fluxes for establishing the respective virtual images are separated from and independent of one another between the flat display and a concave mirror, and is configured by arranging different optical elements so as to correspond to the respective light fluxes.

  • Patent number: 10446365
    Abstract: A method capable of verifying whether operation parameters, such as a focus parameter and an astigmatism correction parameter, of a scanning electron microscope are correctly adjusted. This method includes: determining a ratio of a length of an edge in a first direction to a length of the edge in a second direction perpendicular to the first direction, the edge being an edge of a pattern selected from design data; generating images of the pattern while changing an operation parameter of a scanning electron microscope; calculating an edge sharpness in the first direction of each of the images and calculating an edge sharpness in the second direction of each of the images; determining a ratio of a peak value of the edge sharpness in the first direction to a peak value of the edge sharpness in the second direction; and emitting an alarm if the ratio of the peak values does not coincide with the ratio of the lengths of the edge.

  • Patent number: 9289882
    Abstract: A grinding tool with an eccentric rotation shaft of a grinding disc with attached grinding material installed via a bearing at a position that is shifted from the central drive shaft line of a rotating disc fixed on a drive shaft, comprises a clutch in which a grinding disc-side clutch component member installed on the grinding disc or on the eccentric rotation shaft that is fixed to the grinding disc and a rotating disc-side clutch component member installed on the rotating disc are linked via a sliding surface capable of sliding and of transmitting the drive force. The rotation rate of the grinding disc is limited to a stable range of rotation rates, preventing extreme elevation in the rotation rate and extreme reduction in the rotation rate; the workpiece is ground efficiently; and the tool does not generate marks or patterns on the ground surface.

  • Publication number: 20150302981
    Abstract: There is provided a transformer in which leakage inductance can be adjusted arbitrarily and which can be readily processed and achieves reduction in size. The transformer includes: a primary coil (10) and a secondary coil (12); and a core (14) that forms an annular closed magnetic circuit by being arranged across the primary coil and the secondary coil. A magnetic body (15) having a cross-sectional area smaller than a cross-sectional area of the core is arranged between the primary coil (10) and the secondary coil (12) so as to interpose a spacing between both of its end parts and the core and so as to make a short-cut of the annular closed magnetic circuit.

  • Patent number: 7664523
    Abstract: When a judging unit judges that there is no mobile-apparatus transmission data, a first generating unit decreases a reference value for generating a transmission-power control command, by a value equivalent to an amount of an outer-loop adjustment. A second generating unit compares generated reference value and a line quality that is measured by a measuring unit, when the former is larger than the latter, generates a transmission-power control command for reducing a transmission power of the mobile apparatus, and when the former is smaller than the latter, generates a transmission-power control command for increasing the transmission power of the mobile apparatus.

  • Patent number: 6955494
    Abstract: A reflector guiding an optical axis is housed in a mirror holder with a compression spring disposed therebetween so that the reflector is biased by the compression spring to move backward. A mirror retainer is rotatably supported by a rear cover for the mirror holder and the reflector is supported by a pair of supporting projections and an adjusting screw to bear against the rear surface of the reflector. The reflector tilts as the projection length of the adjusting screw is changed while the direction in which the effective surface of the reflector faces is changed as the mirror retainer is rotated and thereby the angular position of the adjusting screw is changed.

  • Patent number: 6950216
    Abstract: Provided are a light source apparatus capable of preventing a shift in an optical path of a light beam, and an optical scanner comprising the light source apparatus. An optical scanner comprises a light source apparatus in which four light sources corresponding to four colors Y, M, C and B are supported as a unit by one holder. The light sources are integrally disposed in a specific position (a position where the holder is disposed) on an optical base as a supporting base, so even if distortion of the optical base occurs resulting from a dynamic load, ambient temperature or the like, an influence of the distortion is exerted upon each of the light sources supported by the holder to substantially the same extent. Even if a shift in the whole arrangement of the light sources occurs, a large shift in a positional relationship between each light source does not occur.

  • Patent number: 6903858
    Abstract: An optical scanning device is disclosed that includes a rotary polygon mirror and an air current rectifying mechanism. The air current rectifying mechanism is positioned with a surface that is substantially parallel to an end surface of the rotary polygon mirror. At least one specified condition is satisfied to insure that negative pressure regions are prevented from forming on planar surfaces of the rotary scanning mirror when the scanning mirror is rotated by a scanning motor. In this manner, dust that normally tends to be deposited on the scanner mirror planar surfaces by eddy currents that form as a result of these negative pressure regions is prevented from adhering to the rotary scanning mirror surfaces. Thus, optical performance of the scanning mirror is maintained over time.
