Abstract: A wireless system device is a device to be mounted on a vehicle. The wireless system device includes a wireless communication unit, a condition detector, a position obtainer, and an operation controller. The wireless communication unit transmits a radio signal. The condition detector detects a first timing and a second timing. The first timing is a timing when the vehicle shifts from an operation state to a stop state. The second timing is a timing when the vehicle shifts from the stop state to the operation state for a first time after the first timing. The position obtainer obtains a first position and a second position. The first position and the second position are positions where the vehicle is at the first timing and the second timing, respectively. The operation controller controls operation of the wireless communication unit based on a distance between the first position and the second position.

Abstract: A vehicular temperature regulation device includes a refrigeration cycle, a high-temperature cycle, and a low-temperature cycle. The refrigeration cycle includes a heating heat exchanger configured to heat the heat medium in the high-temperature cycle by exchanging heat between the refrigerant and the heat medium, and a cooling heat exchanger configured to cool the heat medium in the low-temperature cycle by exchanging heat between the refrigerant and the heat medium. The vehicular temperature regulation device includes a connection portion that connects the high-temperature cycle and the low-temperature cycle, a regulation portion configured to regulate a flow of the heat medium, and a controller. After the controller stops the compressor, or after the controller receives a stop command of stopping the compressor, the controller controls the regulation portion, a first pump, and a second pump to exchange the heat medium between the high-temperature cycle and the low-temperature cycle.

Abstract: A transmitting device is mountable in a vehicle. A first detector detects entry of another vehicle into vicinity of a vehicle mounted with the transmitting device. A second detector detects stabilization in a relationship between the other vehicle and the vehicle after the first detector detects the entry. A recording unit records a vehicle behavior of the vehicle from timing when the first detector detects the entry of the other vehicle to timing when the second detector detects the stabilization in the relationship between the other vehicle and the vehicle. A transmitter transmits the vehicle behavior recorded in the recording unit after the second detector detects the stabilization.

Abstract: A non-transitory computer-readable storage medium storing a database control program that causes a computer to execute a process, the process including when an update processing for a value of a data item included in a record stored in a database occurs, generating a first record and a second record, the first record including the data item having a value updated by the update processing, the second record including the data item having a value not updated by the update processing, and when a new update processing occurs for the record for which the update processing occurred, performing the new update processing for both of the first record and the second record.

Abstract: A polymerized rosin compound includes a rosin dimer component (A) including a bifunctional rosin dimer component (a1) represented by formula (1): ROOC—X—COOR. In this formula, X represents a rosin dimer residue derived from abietic acid, neoabietic acid, or palustric acid, which are resin acids having conjugated double bonds; and R represents hydrogen, an alkyl group of I to 5 carbon atoms, or a benzyl group. The rosin dimer component (A) contains a bifunctional rosin dimer component (a1) in the amount of 80% by weight or more and a rosin trimer or higher oligomer component (B) in the range from 1.5 to 3.

Abstract: A flowpath structure includes: a supply channel in which a fluid to be supplied to an apparatus flows; a discharge channel in which the fluid discharged from the apparatus flows; and a pilot type opening-and-closing valve disposed in either one channel of the supply channel and the discharge channel. The opening-and-closing valve has a main valve arranged in the either one channel, a pilot channel connecting the supply channel and the discharge channel with each other, a back pressure chamber defined in the pilot channel, and a pilot valve that opens and closes a portion of the pilot channel closer to the discharge channel than the back pressure chamber. The main valve opens and closes the either one channel based on a change in an internal pressure of the back pressure chamber caused by an opening-and-closing operation of the pilot valve.
