  • Publication number: 20190309805
    Abstract: A control apparatus for a vehicle drive-force transmitting apparatus including a dog clutch that is operated by an actuator to selectively connect and disconnect a drive-force transmitting path. In process of switching of the dog clutch from released state to engaged state, the control apparatus determines whether a rotational speed difference of the dog clutch is equal to or larger than a given difference value when a sleeve of the dog clutch is positioned on an engaging side of a synchronizing position for placing the dog clutch into the engaged state, and stops the switching of the dog clutch to the engaged state and causes the actuator to place the dog clutch back into the released state, when determining that the rotational speed difference is equal to or larger than the given difference value with the sleeve being positioned on the engaging side of the synchronizing position.

  • Patent number: 10401285
    Abstract: The present invention relates to an apparatus for measuring surface properties of a polishing pad which measures surface properties such as surface topography or surface condition of a polishing pad used for polishing a substrate such as a semiconductor wafer. The apparatus for measuring surface properties of a polishing pad includes a laser beam source configured to emit a laser beam, and a photodetector configured to detect scattered light that is reflected and scattered by the polishing pad, an optical Fourier transform being performed on the detected scattered light to produce an intensity distribution corresponding to a spatial wavelength spectrum based on surface topography of the polishing pad.

  • Publication number: 20190245417
    Abstract: A control device moves a split claw (11) holding a projecting portion (4d) of an eighth-layer coil segment (4) in a counterclockwise direction D1. At this time, the control device moves first to third extended blades (13a) to (13c) in an outward direction D3 so that the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the outward direction D3. Then, the control device moves the first to third extended blades (13a) to (13c) in an inward direction D4. Through the above steps, the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the counterclockwise direction D1 while being bent in the outward direction D3. As a result, a return force tending to return in the inward direction D4 is generated by an elastic deformation force.

  • Patent number: 10360544
    Abstract: A system effectively performs content information acquisition processing and content purchase processing in which it is necessary to access different servers. If a user views information provided by an information providing server, for example, television program table information, and acquires content related to information selected from among pieces of information included in the television program table information, the user can transmit a content acquisition request including content specification information to a content providing server simply by dragging and dropping the selected information displayed on a display screen onto a toolbar included in a display unit or onto another server information display area. As a result, the user can effectively perform the selection and acquisition of content without switching between connections to various servers.
