Abstract: A biometric information authentication device includes a control unit, wherein, when a first biometric authentication is successfully completed based on biometric information acquired from an operator and registered biometric information preliminarily registered by a registered person and an operation for registering new registered biological information is subsequently performed, the control unit permits registration upon a successful second biometric authentication based on biometric information acquired again and the registered biometric information preliminarily registered by the registered person.

Abstract: A biometric information authenticating device includes a biometric information sensor to detect contact of an operating finger with a reading surface and to read biometric information of the operating finger, an illumination unit including at least one light source, and a control unit to indicate completion of reading of the biometric information by an illumination pattern including a combination of turning on and off of the at least one light source.

Abstract: A vehicle control system includes: an entry/exit management device including a first processor including hardware, the first processor being configured to detect that a user of a vehicle enters or leaves a facility, and output a first signal indicating user's entering the facility and a second signal indicating user's leaving the facility, to a server; and the server comprising a second processor comprising hardware, the second processor being configured to output to the vehicle a third signal for deactivating a smart key function of the vehicle when acquiring the first signal and prohibit unlocking of a door of the vehicle performed by wireless communication, and output to the vehicle a fourth signal for setting the smart key function of the vehicle when acquiring the second signal and permit unlocking of the door of the vehicle performed by wireless communication.

Abstract: An air conditioning system includes: an outdoor unit; indoor units; one or more refrigerant flow path switching devices that switch flow paths of a refrigerant between the outdoor unit and the indoor units; and external pipes extending from the outdoor unit to the indoor units. The air conditioning system is configured such that a sum of a first value and a first correction value is equal to or less than a predetermined upper limit value determined based on an industrial standard, where the first value is based on a total length of the external pipes from the outdoor unit to the indoor units via the one or more refrigerant flow path switching device, and the first correction value is based on a sum of capabilities of the indoor units connected to the one or more refrigerant flow path switching devices.

Abstract: A refrigerant flow path switching device includes: a first header pipe that is connected to a high-and-low-pressure gas connection pipe of a heat source unit in an air conditioner; a second header pipe that is connected to a sucked-gas connection pipe of the heat source unit; a third header pipe that is connected to a liquid connection pipe of the heat source unit; switching units that each correspond respectively to utilization units in the air conditioner and include valves that control refrigerant flows; and a casing accommodating the first header pipe, the second header pipe, the third header pipe, and switching units. The refrigerant flow path switching device switches among refrigerant flow paths, each of which is between the heat source unit and one of the utilization units.

Abstract: A mounting bracket (30) for mounting a drain pump (40) to a heat insulator (25) is integrated with a lid element (32) for blocking an opening of a wire receiving groove (26). When the mounting bracket (30) is mounted to the heat insulator (25), a wire (41) extending from the drain pump (40) is held between the wire receiving groove (26) and the lid element (32).

Abstract: A rotation detecting apparatus including a magnet having alternatively-arranged N-poles and S-poles on a rotator, and a magnetoresistive element having plural (six) magnetoresistive units which are continuously arranged at a predetermined interval on a stator, and signal output units which are provided at prescribed three positions of connection points of the plural detection units, wherein the detection units serving to detect magnetic field which is varied in accordance with rotation of the rotor, and the signal output units serving to output signals whose phases are different from one another by 120.degree. on the basis of the detection of the magnetic field by the detection units.
