  • Patent number: 10740225
    Abstract: A radio communication processor receives first received data including first write data, a first address within a first area of a nonvolatile memory, and error detection information or second received data including second write data whose data amount is larger than a data amount of the first write data and a second address within a second area of the nonvolatile memory. If the radio communication processor receives the first received data, then a controller stores the first write data in a volatile buffer. If there is no error in the first write data, then the controller reads out the first write data from the volatile buffer and stores the first write data in the first area. If the radio communication processor receives the second received data, then the controller stores the second write data in the second area without storing the second write data in the volatile buffer.

  • Patent number: 10656664
    Abstract: The disclosure provides a voltage generator including a first voltage regulator which provides an output voltage to an output terminal according to a reference voltage; a second voltage regulator which determines whether to operate in an enable mode or a disable mode according to an enable signal and provides the output voltage to the output terminal according to the reference voltage when operating in the enable mode; an initial voltage generator which sets a feedback voltage of the second voltage regulator to be an initial voltage value close to the reference voltage when the enable signal switches the second voltage regulator from the disable mode to the enable mode, such that the feedback voltage of the second voltage regulator is able to be locked to the reference voltage fast, and a settling time and an overshoot/undershoot of the output voltage are reduced.

  • Patent number: 10360415
    Abstract: A radio communication processor receives data to which identification information is assigned and transmits a response signal indicative of whether or not application processing based on the data is normally performed. An application controller controls the application processing on the basis of the data and detects whether or not the application processing is normally performed. A controller detects on the basis of the identification information that the same data are received in succession due to retransmission, nullifies, when the application controller detects that the application processing based on the data received earlier is normally performed, control of the application processing based on the data received later to be performed by the application controller and instructs the radio communication processor to transmit the response signal which indicates that the application processing is normally performed.

  • Patent number: 10294994
    Abstract: The present invention is intended to provide a machine component composed of metal and rubber that results in no increase of material costs for an adhesive or increase of manufacturing costs for metal molding, causes no contamination of the metal mold or generates no foreign matter on the metal mold due to adhesion of the adhesive at the time of molding, causes no failure by separation of the adhesive from a fitting portion at the time of fitting the metal component, and is clean and favorable in appearance. A machine component 1 composed of metal and rubber is formed by applying a thermoset resin adhesive A to a surface of a metal component 2 of a predetermined shape, and vulcanizing and adhering a rubber 3 of a predetermined shape to part of the surface of the metal component 2 by metal molding.

  • Publication number: 20190101212
    Abstract: A plated coating of metal having a higher ionization tendency than iron is provided on at least either one of: (i) a metal fitting portion between a sleeve of a stainless steel-made slinger of a rotary seal and an inner ring that is a steel-made radially inner member; and (ii) an outside air side surface of the slinger, which includes an outside air side end portion of the metal fitting portion. Even when the solution containing the electrolyte is present on an outside air side of the fitting portion, the plated coating of metal having a higher ionization tendency than iron corrodes first instead of the inner ring that is a steel-made member. Without lowering durability and reliability, a progress of corrosion of a steel-made member is delayed even when a solution containing an electrolyte is present around a contact portion between a stainless steel-made member and a steel-made member.
