Patent number: 11778698Abstract: An infrared heating device that appropriately sets positions of infrared lamps and a radiation thermometer relative to an object to be heated and is easily positioned includes: an infrared irradiator that irradiates infrared rays to an object to be heated to heat the object to be heated; a holding member that holds the infrared irradiator; a radiation thermometer that measures a temperature of a surface of the object; and a pair of laser pointers that irradiate laser beams to the surface of the object from different positions. The pair of laser pointers are disposed to cause the respective laser beams to be coincident in position with each other at one point on the surface of the object when a distance between the surface of the object and the infrared irradiator is a predetermined distance.Type: GrantFiled: August 24, 2017Date of Patent: October 3, 2023Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Toshikatsu Nohara, Takashi Shibutani, Shigenari Horie, Makoto Tamura

Publication number: 20120303225Abstract: An industrial vehicle 1 includes a brake 5 that applies a driving force or a braking force to a vehicle body 22, a lift pressure sensor 632 that detects pitching vibration of a vehicle body, and a pitching control unit 62 that calculates a pitching control torque for suppressing pitching vibration and generates a pitching control signal for causing the brake 5 to output the pitching control torque. When the industrial vehicle 1 runs under a load, the pitching control unit 62 calculates the pitching control torque based on an output value from the lift pressure sensor 632 to output the pitching control signal. The brake 5 is then driven based on the pitching control signal.Type: ApplicationFiled: June 22, 2010Publication date: November 29, 2012Inventors: Kensuke Futahashi, Yusuke Kinouchi, Ryuichi Umehara, Takuya Nakada, Takashi Shibutani, Masaru Higuchi
