Abstract: An object of the present invention is to provide a display nail tip suitable for being arranged, as samples of nail tips for nail art to be provided to customers, in a hard case, frames, boards, pedestals or the like and being presented to the customers or displayed in shops. Another object of the present invention is to provide a nail tip for the display nail tip described above and a nail tip positioning assistance tool. A display nail tip of the present invention includes a nail body (1) and a nail tip positioning assistance tool (14a, 14b) for assisting arrangement of the nail body on a nail tip display tool. The nail tip positioning assistance tool is integral-molded with any one of a thickness portion (3) of the nail body, a thick peripheral edge (1h) of the nail body, a concavely curved surface (1b) of the nail body, a base portion (4) arranged on the concavely curved surface (1b) of the nail body and a convexly curved surface (1a) of the nail body.

Abstract: A control apparatus for a multi-phase rotating electric machine includes at least one electric power converter, a command value calculator and an input voltage determiner. The at least one electric power converter converts DC power into multi-phase AC power and supplies the multi-phase AC power to the rotating electric machine. The command value calculator calculates command values for operating the at least one electric power converter. The input voltage determiner determines whether an input voltage of the at least one electric power converter is within a normal operation range. When the input voltage is determined by the input voltage determiner to be outside the normal operation range, the control apparatus switches control to ignore voltage change or current change caused by the reverse input of an external force to the rotating electric machine from a load side or suppress control fluctuation caused by the reverse input of the external force.

Abstract: An abnormality diagnosis apparatus performs: a first step of diagnosing a shortage of precharge voltage or a short-circuit failure between electrodes of a capacitor based on a detection value of a precharge voltage detection circuit in a state where a first relay and a second relay are turned off, and a precharge circuit is operated; a second step of diagnosing, after a normal determination in the first step, a disconnection failure of a precharge path based on the detection value of the precharge voltage detection circuit or a detection value of an inter-relay voltage detection circuit in a state where the first relay and the second relay are turned off, and the precharge circuit is not operated; and a relay failure diagnosis step of diagnosing, after a normal determination in the second step, a short-circuit failure and an open failure of the first relay or the second relay.

Abstract: An electronic control unit includes two inverters, a magnetic sensor, a failure detection unit, an inverter driving unit, a signal examination unit, and a failed element identification unit. The magnetic sensor detects a magnetic flux generated around a winding. The failure detection unit detects an ON-state failure of the inverter. When the ON-state failure is detected, the inverter driving unit stops driving the inverter to which the ON-state failure has been detected, and continues driving the other inverter. The signal examination unit examines a presence or absence of a special signal. When there is a signal appearing according to a special magnetic flux, the failed element identification unit identifies a failed switching element based on a motor electric angle generated by the signal.

Abstract: An information sharing system suitable for sharing golf-related information among a plurality of golf players enables mutual communication between a server device and respective player terminals of a plurality of golf-players. When the server device receives a request to create a golf scorecard from the player terminal, the server device generates a scorecard ID and transmits the same to the player terminal; when the server device receives a request to share the golf scorecard with the other golf players, the server device generates a share password and transmits the same to the one player terminal; when the server device receives a request to authenticate the share password, the server device re-generates the scorecard ID on the basis of the share password, and transmits it to the player terminal, and, the player terminal re-creates a golf scorecard that can be shared.
