  • Publication number: 20230377222
    Abstract: A remote computer sequentially detects positions of an indicator on a sensor surface at a predetermined sampling rate using an input sensor, and sequentially transmits pieces of report data including the positions to a host computer. A host computer detects a gesture based on a series of the pieces of report data received from the remote computer, generates one or more deformed images by imparting a deformation corresponding to contents and an amount that are indicated by the gesture, to one or more images, transmits the one or more deformed images to the remote computer, and performs cancelation processing that cancels generation of the one or more deformed images when one of the pieces of report data received from the remote computer includes an end report indicating that the indicator has been moved away from the sensor surface.

  • Publication number: 20220349444
    Abstract: A sintered bearing 1 is formed by sintering a raw material powder containing aluminum fluoride. The sintered bearing 1 has a structure obtained by sintering an aluminum-copper alloy and contains 3 to 13 mass % aluminum and 0.05 to 0.6 mass % phosphorus, copper as a main component of the remainder, and inevitable impurities. The sintered bearing 1 is manufactured by performing sintering in a closed space 23, and by, under the assumption that all aluminum fluoride contained in the raw material powder is gasified in the closed space 23, controlling the concentration of the aluminum fluoride gas to be 5 ppm or more, thus performing the sintering.

  • Patent number: 11007572
    Abstract: A sliding member (1) includes an iron and steel-based sintered compact containing chromium, molybdenum, and carbon and having a content of chromium, of 5 mass % or less. The sliding member (1) includes: a compound layer (11) which has a sliding surface (1a) and is formed mainly of an iron and steel nitride; and a diffusion layer (12) which is adjacent to the compound layer (11) and has an iron and steel structure into which nitrogen and carbon diffuse. The concentrations of carbon and nitrogen in the diffusion layer (12) are gradually reduced with increasing depth from the sliding surface (1a).
