A pod propulsion device includes: a pod configured to be disposed in water; a rotation shaft supported by the pod to be rotatable about a predetermined axis and having an end portion projecting out from the pod; a screw fixed to the end portion of the rotation shaft; an electric motor installed in the pod to rotationally drive the rotation shaft; multiple guide blades integrally formed on the pod to be arranged at intervals in a circumferential direction of the pod, each guide blade extending out radially from an outer surface of the pod; and a cooling circuit for cooling the electric motor, wherein the cooling circuit includes a cooling liquid passage formed to pass through an interior of at least one of the guide blades.

Pod propulsion device

A server apparatus includes a processor configured to manage identification information of a registered vehicle registered in advance, acquire identification information on a vehicle of a user who wants to replace the batteries from a vehicle key device, acquire fee-related information from the vehicle key device, the fee-rerated information being at least one of a travel distance and a battery usage amount of the vehicle of the user, calculate a usage fee of the batteries based on the fee-related information, determine permission and prohibition to replace a battery, control a lock device which enables taking-out of the batteries accommodated in the battery stand, determine the permission and prohibition to replace the batteries based on the identification information acquired from the vehicle key device and the identification information, and unlock the lock device when it is determined to permit replacing the batteries.

Server apparatus

A driving unit includes a motor, a control unit and a partition member. The control unit includes an inverter configured to transfer electric power to and/or from the motor, and a casing configured to accommodate the inverter. The partition member is disposed between the motor and the inverter. The partition member includes a first heat conductive member, and a second heat conductive member disposed at a first side of the first heat conductive member in a thickness direction and having a thermal conductivity lower than that of the first heat conductive member and a third heat conductive member disposed at a second side of the first heat conductive member in the thickness direction of the first heat conductive member and having a thermal conductivity lower than that of the first heat conductive member. The heat conductive member is coupled to the casing.

Driving unit

An actuator capable of preventing a malfunction of the actuator due to iron powder contained in working fluid and the abrasion of a cylinder and a piston is provided. The actuator includes a cylinder () extending in a vertical direction and having an opening (), a piston () moving inside the cylinder (), and a stroke sensor () that detects a position of the piston (). The stroke sensor () includes a member to be detected () which is a magnet, and a sensor () which detects the member to be detected (). The member to be detected () is located below a lower edge portion () of the opening ().

Actuator and fluid pressure control circuit having the same

A method of setting an actuator capable of accurately detecting a position of a piston using a plurality of sensor units is provided. The method includes a detection value acquisition step of moving a piston in a direction of an axis inside a cylinder and acquiring a detection value from each of a first sensor unit and a second sensor unit for each position of the piston, and a controlling sensor unit-setting step of setting a controlling sensor unit that is used for control of a two-way piston from among the first sensor unit and the second sensor unit on the basis of the detection values obtained for the first sensor unit and the second sensor unit.

Method of setting actuator and fluid pressure control circuit

A breather device that is attached to a case of a transmission and performs ventilation in the case, includes: a main body member including a storage portion with a closed bottom and an open upper end; and a cover member configured to close the upper end of the main body member and including a vent hole for ventilation to outside. The storage portion comprises a first chamber having, in a bottom portion, a communicating port communicating with an interior of the case, and a second chamber configured to receive a liquid entering from the vent hole.
