Patent number: 11154976Abstract: A tool includes a switch and a controller. The switch is configured to cause an electric component to operate. The switch includes a switch manipulation part and a load sensor. The switch manipulation part is configured to manipulate the switch. The load sensor is configured to detect a load corresponding to a pressing force according to a manipulation of the switch manipulation part. The controller is configured to correct an output corresponding to the load detected by the load sensor. The switch is configured to cause the electric component to operate based on the output corrected by the controller.Type: GrantFiled: December 2, 2019Date of Patent: October 26, 2021Assignee: MAX CO., LTD.Inventors: Tomohide Tsutsui, Yuusuke Ohsawa, Tomohiko Serita

Patent number: 9528506Abstract: An inverter substrate in which heat generating components which make up an inverter control unit are mounted on a rear surface side thereof is accommodated in a case which is made of a material having a good thermal conductivity in such a manner that the heat generating components are closely contact with a base of the case. The case is provided between a pair of air tanks which are disposed parallel to each other at an interval and on a lower side of at least either of an electric motor and compressors in such a manner as to be oriented downwards so that the base is located at an upper position. An air flow generated by cooling fans which are driven by the electric motor is introduced to flow along the base of the case to thereby cool the heat generating components via the case.Type: GrantFiled: December 22, 2005Date of Patent: December 27, 2016Assignee: MAX CO., LTD.Inventors: Tsutomu Yoshida, Tomohiko Serita

Patent number: 7850071Abstract: A work management data collection system 1 is provided with a data collection mechanism in a tool 2, and by counting a number of times a work operation has been executed or the like, obtains a work data identifying the work task that has been executed and detects a time data required for the work task. The system is provided with an RFID tag 3a on an ID card 3 held by a worker, and by writing data into the ID card 3 of the worker who carried out the work task, using an RFID reader/writer 4 provided on the tool 2, the system obtains data necessary for the work management from the ID card 3 of the worker.Type: GrantFiled: February 15, 2006Date of Patent: December 14, 2010Assignee: Max Co., Ltd.Inventors: Gorou Sakamoto, Tomohiko Serita

Publication number: 20080112823Abstract: An inverter substrate 28 in which heat generating components 26 which make up an inverter control unit 9 are mounted on a rear surface side thereof is accommodated in a case 30 which is made of a material having a good thermal conductivity in such a manner that the heat generating components 30 are closely contact with a base of the case 30. The case 30 is provided between a pair of air tanks 5, 6 which are disposed parallel to each other at an interval and on a lower side of at least either of an electric motor 2 and compressors 3, 4 in such a manner as to be oriented downwards so that the base is located at an upper position. An air flow generated by cooling fans 20, 21 which are driven by the electric motor 2 is introduced to flow along the base of the case 30 to thereby cool the heat generating components 26 via the case 30.Type: ApplicationFiled: December 22, 2005Publication date: May 15, 2008Inventors: Tsutomu Yoshida, Tomohiko Serita
