  • Patent number: 10920918
    Abstract: A spiral pipe (9) is formed by joining edges of adjacent turns of a strip member (90) while helically winding the strip member using a pipe-making apparatus. A propulsive reaction force for moving in a winding direction of the strip member is imparted to a following strip portion (92) or a preceding spiral pipe portion (91) of the strip member by a propulsive reaction force imparting portion of the pipe-making apparatus. The following strip portion follows a preceding spiral pipe portion that has already been made into a pipe. A resisting force in a direction opposite to the propulsive reaction force is imparted to the strip member along the winding direction by a friction between a resisting force imparting portion and the strip member generated while the strip member is moved forward. In this arrangement, a diameter limiting frame can be omitted, and thereby, the pipe-making apparatus can be downsized.

  • Patent number: 10903320
    Abstract: A transistor device includes a field plate that extends from a source runner layer and/or a source contact layer. The field plate can be coplanar with and/or below a gate runner layer. The gate runner layer is routed away from a region directly above the gate metal layer by a gate bridge, such that the field plate can extend directly above the gate metal layer without being interfered by the gate runner layer. Coplanar with the source runner layer or the source contact layer, the field plate is positioned close to the channel region, which helps reduce its parasitic capacitance. By vertically overlapping the metal gate layer and the field plate, the disclosed HEMT device may achieve significant size efficiency without additional routings.

  • Publication number: 20200364661
    Abstract: A server uses a travel history of an electric-powered vehicle to estimate the deterioration state of a battery, and stores the estimated deterioration state in association with information for identifying the electric-powered vehicle. When a transmission request for deterioration information is executed at a user terminal, the server transmits the deterioration information to the user terminal. When a shop terminal receives information on a replacement condition for the battery from the user terminal, the shop terminal transmits, to the user terminal, inventory information corresponding to a replacement battery that satisfies the replacement condition.

  • Patent number: 10641790
    Abstract: Provided is a scanning probe microscope being able to shorten an observation time of a minute observation object. Main measurement is performed to acquire a surface image of a sample based on a detection signal in a measurement range of a plurality of lines by repeating, for each line, processing of scanning a cantilever at predetermined second intervals in a Y-direction after acquiring the detection signal at predetermined first intervals while scanning the cantilever on a line having a predetermined length along an X-direction. Preliminary measurement is performed to acquire a surface image of the sample by acquiring the detection signal at intervals wider than the first intervals or scanning the cantilever in the Y-direction at intervals wider than the second intervals before the main measurement, the surface image of the sample being coarser than the surface image in the main measurement.

  • Patent number: 10598691
    Abstract: A scanning probe microscope includes a light source, a detector, a housing, an opening and closing door, an opening and closing sensor, a control unit, and the like. The opening and closing door is provided in the housing. The control unit 16 also functions as the light intensity change processing unit 164. In the scanning probe microscope, when the opening and closing sensor detects opening and closing of the opening and closing door, the light intensity change processing unit automatically changes the intensity of light irradiated from the light source based on a detection result of the opening and closing sensor. Therefore, it is possible to omit light intensity adjustment work performed manually by the user. As a result, the workability of the user when using the scanning probe microscope 1 can be improved.
