Abstract: A vibration monitoring device includes: a rotation sensor for outputting a rotation signal synchronized with rotation of a rotational shaft; an output device for outputting a filter command value corresponding to a rotation speed of the rotational shaft calculated from the rotation signal; and at least one filter for extracting, in response to input of the rotation signal and the filter command value, a signal in a passband set according to the filter command value from the rotation signal as a vibration signal from which vibration information of the rotational shaft can be obtained.

Abstract: An absorption heat pump device includes a heat exchange unit through which a heat exchange fluid flows, a rotor that includes a hollow rotary shaft member including a first internal flow path and discharges a solution in the first internal flow path by a centrifugal force, and an application member that moves with rotation of the rotor to apply the solution, which flows through the first internal flow path and is discharged, along a heat transfer surface of the heat exchange unit.

Abstract: An in-vehicle absorption heat pump device comprises a regenerator; an in-vehicle heat source heating absorbent in the regenerator; a gas-liquid separator; a condenser condensing gas phase separated from the absorbent; an evaporator evaporating a condensate to form vapor; an absorber for bringing the relatively concentrated absorbent in liquid phase in contact with the gas phase to cause the absorbent to absorb the gas phase and be relatively diluted; an absorbent circulation source circulating the absorbent; a bypass passage connecting a liquid-phase storing portion of the gas-liquid separator and the regenerator while bypassing the absorber; and a bypass transfer source in the bypass passage returning the absorbent in the gas-liquid separator to the regenerator. To dilute absorbent in the absorber, a diluent passage allows the condenser and the absorber to communicate and the condensate in the condenser to be supplied to the absorber through the diluent passage by a dilution element.

Abstract: An electric power tool has an electric motor disposed in a main body and a power supply circuit electrically connected to the electric motor by wires to supply electric power to the electric motor. A switch is disposed in the power supply circuit so as to electrically open and close the power supply circuit. A movable member is supported by the main body, a detector is disposed in the main body to detect a movement of the movable member and the switch is configured to electrically open the power supply circuit when the detector detects the movement of the movable member. The wires connected to the electric motor are not connected to the detector so that the length of the wires is shortened.
