Publication number: 20230398667Abstract: An electric tool includes a tightening unit, a sensor unit that measures at least a tightening torque provided by the tightening unit to obtain working data relating to a result of measurement, a communications unit that transmits the working data, and a storage unit that stores the working data. The electric tool has, as a communications mode for transmitting the working data stored in the storage unit from the communications unit, a first communications mode and a second communications mode. The communications unit is configured to, in the first communications mode, transmit, during an interval between the tightening tasks, first working data which is part of the working data stored in the storage unit, and in the second communications mode, after completion of all of the tightening tasks, transmit at least second working data which is the working data stored in the storage unit except the first working data.Type: ApplicationFiled: May 31, 2023Publication date: December 14, 2023Inventors: Keisuke MASE, Naoki TSURUTA

Patent number: 10879689Abstract: A control circuit turns ON or OFF a switch that is provided at a midpoint of a wire. Thus, power supply via the wire is controlled. A current output circuit outputs a current that corresponds to a current flowing through the wire to a resistance circuit. In the resistance circuit, a series circuit of a resistor (R2) and a capacitor (C1) is connected in parallel to a resistor (R1). The control circuit) turns OFF the switch if the end-to-end voltage value of a voltage across both ends of the resistance circuit is larger than or equal to a reference voltage value.Type: GrantFiled: November 30, 2016Date of Patent: December 29, 2020Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Shunichi Sawano, Yuuki Sugisawa, Kota Oda, Keisuke Mase

Patent number: 10547194Abstract: In a power supply control apparatus, if a switching signal input from a microcomputer to a control circuit instructs switching on of a semiconductor switch, when an input voltage that is input to the drain of the semiconductor switch is higher than or equal to a predetermined voltage, the control circuit drives a charging circuit. The charging circuit charges a capacitor (Cs) via a diode (D1). Accordingly, a voltage at the gate of the semiconductor switch taking a potential at the source of the semiconductor switch as a reference becomes higher than or equal to a predetermined voltage, and thus the semiconductor switch is switched on. While driving the charging circuit, the control circuit keeps driving the charging circuit even if the input voltage becomes lower than the predetermined voltage.Type: GrantFiled: November 28, 2016Date of Patent: January 28, 2020Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Yuuki Sugisawa, Shunichi Sawano, Kota Oda, Keisuke Mase

Publication number: 20180358806Abstract: In a power supply control apparatus, a control circuit adjusts a resistance between a drain and a source of a semiconductor transistor by adjusting the voltage at a gate of the semiconductor transistor. After the control circuit has lowered the resistance between the drain and the source, a control portion determines whether or not the voltage at the source detected by a voltage detecting portion is larger than or equal to a standard voltage. If the voltage at the source is larger than or equal to the standard voltage, the control circuit again lowers the resistance between the drain and the source. If the voltage at the source is smaller than the standard voltage, the control circuit adjusts the resistance between the drain and the source to a resistance at the time when determination was performed or larger.Type: ApplicationFiled: December 21, 2016Publication date: December 13, 2018Inventors: Keisuke Mase, Yuuki Sugisawa, Kota Oda, Shunichi Sawano
