  • Publication number: 20200290699
    Abstract: To provide a parking brake apparatus for a saddled vehicle actuated in response to a reverse rotation on a throttle grip which is set in a simplified structure. A parking brake apparatus for a saddled vehicle includes a parking brake caliper configured to restrict a rotation of a rear wheel while the motorcycle is parked; a steering handle configured to steer a front wheel; and a throttle grip mounted on the steering handle and configured to control output of a power unit. The control unit actuates the parking brake caliper by a motor when at least the throttle grip is reversely rotated and the vehicle speed is zero. The throttle grip being reversely rotated is detected according to information from a throttle position sensor which is interlocked with the throttle grip.

  • Patent number: 10589531
    Abstract: A liquid ejection head can suppress the influence of static electricity and the increase of a mounting force as well as downsize and save space of the liquid ejection head. The liquid ejection head is attachable and detachable with respect to a body connector provided on a liquid ejection apparatus body. Further, the liquid ejection head includes a head connector including a terminal which can be electrically connected to the body connector and a grounding member which is held at a coverage position where the terminal is covered in a non-contacting state with the body connector. The grounding member is formed with a deformable electroconductive member, and, as the head connector is made to move to a mounting position with respect to the body connector, is pressed by the body connector and is displaced to a position apart from the coverage position. Thus, the body connector can be connected with the terminal.

  • Patent number: 10324875
    Abstract: Provided are a data processor, and a control system, in which an interrupt controller and an event link controller are adopted. The event link controller responds to a generated event signal to output a start control signal for controlling start of an operation of a circuit module. The circuit module is able to generate an event signal. The event link controller generates the start control signal according to the correspondences between event signals and start control signals which are defined by event control information. The links between the event signals and start control signals can be prescribed by the event control information. Therefore, operations of circuit modules prescribed by such links can be controlled sequentially. The control neither involves save and return processes by CPU as in the interrupt processing, nor needs priority level control as executed on competing interrupt requests.

  • Patent number: 10006784
    Abstract: A correction circuit stores data for obtaining coefficients of a relational expression indicating a relationship between a disturbance magnetic flux and a rotational angle error. Then, the coefficients are obtained from the data for obtaining the coefficients, and a detection result of a magnetic sensor is corrected based on the coefficients obtained, a relational expression, and a detection result of a disturbance magnetic flux detection circuit. Since it is possible to obtain the rotational angle error with respect to the disturbance magnetic flux from the coefficient obtained and the relational expression, it is not necessary to store the data indicating the relationship between the disturbance magnetic flux and the rotational angle error for all of the disturbance magnetic flux value in disturbance magnetic flux regions that may be applied.

  • Publication number: 20160373253
    Abstract: A first determining unit determines a period of time during which there is possibility of wiretapping of data present in a data communication channel connected to another communication device. A second determining unit determines, with a length of the period of time as unit of time, size of a cryptographic key used for encrypting data to be transmitted to the other communication device via the data communication channel during each unit of time. A first obtaining unit obtains a first cryptographic key having the size, from a first storing unit storing therein cryptographic keys shared with the other communication device. A recognizing unit recognizes possibility of wiretapping with respect to the data communication channel. Until the possibility of the wiretapping is recognized, a encrypting unit repeatedly encrypts data to be transmitted to the other communication device during each unit of time using the first cryptographic key.
