Abstract: A solenoid valve includes a valve portion and a solenoid portion. The valve portion has a sleeve and a valve body inserted into the sleeve. The solenoid portion includes a stator core having a magnetic attraction core, a sliding core, a magnetic flux passage suppressing portion that suppresses the passage of magnetic flux between the sliding core and the magnetic attraction core, a magnetic yoke, a coil portion, a plunger, and a magnetic tubular base portion. The base portion is fastened to a first outer peripheral surface of an end on the solenoid portion side in the axial direction of the sleeve, is arranged outside a radial direction of a second outer peripheral surface of the end on the valve portion side in the axial direction of the magnetic attraction core, and comes into contact with the yoke inside the yoke.

Abstract: To accurately achieve synchronization between a master and a slave that perform wireless communication. A synchronization device that synchronizes time-series data between a master and a slave by wireless communication, the master including a packet transmission unit that transmits a plurality of packets at a predetermined interval, and the slave including a synchronization unit that synchronizes time-series data transmitted by the master and time-series data received by the slave on the basis of the interval between the plurality of packets.

Abstract: An abnormal torque evaluation apparatus is applied to an electrically driven vehicle configured to drive left and right driving wheels independently with respective electric motors and also configured to independently drive the left and right driving wheels by means of the electric motors driven responsively to respective torque commands. Also provided are a yaw jerk detection means for detecting a yaw jerk and an abnormal torque evaluator for evaluating, based on the yaw jerk, the presence or absence of the occurrence of abnormal motor torque at the electric motors.

Abstract: A combustion of the present invention has a burner, a combustion fan supplying air to the burner, revolution rate detection means for detecting a revolution rate of the fan, and an air-flow rate sensor for detecting an air-flow rate of the air. The combustion device further has a temperature sensor for detecting a temperature at the combustion device and diagnosis means for performing a self-diagnosis to determine a ventilation condition based on a relationship between the revolution rate and the air-flow rate. The diagnostic means correct the detected revolution rate or the air-flow rate based on the temperature of the combustion device in the process of performing the self-diagnosis. The diagnosis means perform the self-diagnosis after a predetermined time has passed until there is no temperature variance in the combustion device since a combustion halts.
