  • Publication number: 20220003295
    Abstract: When a contact area with a chain guide is reduced to a small area by forming a back surface of a link plate into a convex portion having a round shape or the like, a friction coefficient in a fluid lubrication region is reduced (region E). A coating film containing 10% or more of chromium is formed on the link plate. A friction modifier made of a molybdenum compound such as MoDTC and added to a lubricating oil promotes generation of MoS2 by the chromium coating film, and prevents an increase in the friction coefficient in a boundary lubrication region.

  • Patent number: 11044515
    Abstract: A transmission/reception system includes a transmitter and a receiver. The transmitter includes a first circuit that: acquires plural pieces of broadcast image data; categorizes the broadcast image data at least into first and second groups; generates program guide screen data that switches between first and second program guide screen data; generates temporal information about the predetermined time interval and broadcast program identification information; and transmits the screen data and the information. The receiver includes a second circuit that: receives the data and the information; outputs the program guide screen data; detects, when any one of the display frames is selected by a user operation, broadcast program identification information contained in the first or second program guide screen data; and performs control in such a way that the broadcast image data corresponding to the detected broadcast program identification information are output from the image data output device.
