Publication number: 20240084912Abstract: Provided are a thermostat device and a method for manufacturing the same, capable of minimizing an increase in size of the thermostat device, and where a seal member is easily assembled and cost can be minimized. This thermostat device includes a housing, attached to a mounting hole of a counterpart member, that has a flow path for a coolant formed therein, a seal member that creates a liquid-tight seal between the counterpart member and the housing, a thermo-element that expands and contracts in accordance with the coolant temperature, a valve body that opens and closes the flow path due to the expansion and contraction of the thermo-element, and a coil spring that biases the valve body in a closing direction, the housing having formed therein a deformed annular groove into which the seal member fits, and the seal member having a perfectly circular shape in a natural length state.Type: ApplicationFiled: November 11, 2021Publication date: March 14, 2024Inventors: Tetsuya NISHIMURA, Masayuki NUMATA

Publication number: 20240077539Abstract: In a technique for monitoring a state of a battery, battery monitoring information is acquired via wireless communication from monitoring devices that acquire the battery monitoring information from the battery. A predetermined process is executed based on the battery monitoring information. Instructions are transmitted to the monitoring devices via unicast communication and broadcast communication within a communication cycle. The instructions include an instruction transmitted via the unicast communication to each of the monitoring devices about acquisition of the battery monitoring information, and an instruction transmitted via the broadcast communication to the monitoring devices about a timing of acquisition of the battery monitoring information.Type: ApplicationFiled: August 24, 2023Publication date: March 7, 2024Inventors: Shogo SHIGEMORI, Tatsuhiro NUMATA, Tetsuya WATANABE

Publication number: 20240068588Abstract: The thermostat device includes a housing having a valve seat formed thereinside, a thermo-element having one end inserted inside the housing, a valve body seated on or separated from the valve seat by the extension/contraction of the thermo-element, a coil spring biasing the valve body toward the valve seat, and a frame supporting one end of the coil spring. The housing has a hollow body part opening at one end, paired legs erecting from the opening edge of the body part, on whose leading ends the frame is hooked, and ribs provided at the opening edge and contiguous to each root side of the legs. The outer surface of each leg is arc-shaped, and the outer surface of each rib is curved or inclined to extend from the outer surface of the corresponding leg toward the inner side of a circle connecting the outer surfaces of the pair of legs.Type: ApplicationFiled: November 11, 2021Publication date: February 29, 2024Inventors: Tetsuya NISHIMURA, Masayuki NUMATA
