Abstract: A travel control method comprises: learning points which a vehicle has traveled over based on images of the surroundings of the vehicle captured with a camera mounted on the vehicle; learning the travel trajectory of the vehicle based on vehicle signals obtained from the vehicle; determining whether the vehicle has passed the points based on the images captured with the camera; and performing travel control of the vehicle by using the travel trajectory learned based on the vehicle signals as a target trajectory between the points.

Abstract: The outer peripheral surface of a connector, to which a connector seal structure is applied, is provided with an engaging section that engages with a seal member. A rib of the engaging section locks the seal member in the inserting direction of the connector. The seal member is provided with a cutout section formed by cutting out a part of the rib, or a protruding section that engages with the rib.

Abstract: Disclosed herein is an air conditioner including: a rectifier including a plurality of capacitors connected in series to each other, a switching device configured to control a flow of current supplied to the respective capacitors to charge or discharge the plurality of capacitors, a voltage detector configured to detect an output voltage of the plurality of capacitors, and a current detector configured to detect the current; and an inverter configured to generate alternating current by receiving an output voltage of the rectifier.

Abstract: A connector assembly comprises a first connector and a second connector matable with the first connector in a mating direction. The first connector includes a housing and a slider held by the housing and slidable with respect to the housing in a direction intersecting the mating direction. The slider has a slider backlash restraining device disposed on an inner wall. The slider slides in a first direction to cause the second connector to move in the mating direction and slides in a second direction opposite to the first direction to cause the second connector to move in a direction opposite to the mating direction. The second connector has a connector backlash restraining device disposed on an outer wall of the second connector. The slider backlash restraining device abuts the connector backlash restraining device when the first connector is mated with the second connector.

Abstract: A check valve (1) includes a casing (2) having a valve seat (10) formed in a flow path and a valving element assembly (21) disposed in the casing. A top (23) of a valving element (22) is received in a large-diameter portion (38) of a through-hole (37) in a support member (35) of the valving element assembly. A narrow flow path portion (68) is formed between an arcuate portion (46) of an outer periphery (45) of the support member and a second enlarged-diameter portion (11) of the casing. The narrow flow path portion (a first portion of an intermediate flow path) is communicated with a back-pressure chamber (50) defined in the support member at the rear of the top of the valving element through a communicating passage (67) including a gap (66) between the outer periphery of the valving element and the inner periphery of the large-diameter portion and grooves (27) on the rear surface of the top of the valving element.

Abstract: A first check valve has a narrow flow path portion (68) formed between an arcuate portion (46) of the outer periphery (45) of a support member and a second enlarged-diameter portion (11) of a casing. The narrow flow path portion (first portion of an intermediate flow path) is in fluidic communication with a back-pressure chamber (50) defined in the support member at the rear of the top of a valving element through a communicating passage (67) including a gap (66) between the outer periphery of the valving element and the inner periphery of a large-diameter portion (38) and grooves (27) on the rear surface of the top of the valving element. Thus, a low static pressure of fluid flowing through the narrow flow path portion is introduced into the back-pressure chamber to move the valving element by a large differential pressure during the supply of fluid, thereby allowing the valve opening to become larger than in the conventional apparatus and enabling a reduction of pressure losses.
