Patent number: 11090776Abstract: An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.Type: GrantFiled: November 15, 2017Date of Patent: August 17, 2021Assignee: HORKOS CORPInventors: Hiroaki Kiso, Kunihiro Ikeda

Patent number: 8790053Abstract: A cutting liquid supply device in a machine tool is configured to remove gas mixed in a cutting liquid supply line to improve the response of discharging a mist of cutting liquid. Cutting liquid is supplied from a pump (42) through a rotary joint (28) to a mist generation device (24) within a rotating spindle (29). The pressure of the cutting liquid is measured by a pressure sensor (47). An air vent device (30) for opening and closing, with respect to atmospheric pressure, piping (3) that supplies the cutting liquid is provided above the rotary joint (28). A detection signal is inputted in the control board (70) from the pressure sensor (47), and when the control board (70) detects, after the pump (42) stops the supply of the cutting liquid to the piping (3), that the pressure of the cutting liquid does not decrease to a level lower than a predetermined threshold value, the control board (70) instructs the air vent device (30) to open the piping (4) to the atmosphere.Type: GrantFiled: April 9, 2010Date of Patent: July 29, 2014Assignee: Horkos CorpInventors: Tadashi Makiyama, Atsushi Maeda, Shinya Takeda, Takuya Kawamoto, Kunihiro Ikeda, Sadaharu Kittaka

Patent number: 7071472Abstract: In an irradiation control device which extends a longevity of an LED, a feedback control is performed to an irradiating portion by an output signal of a photo device provided in relation to the irradiating portion, thereby making brightness fixed. Alternatively, by performing image processing to an image taken by a camera, brightness on a screen is calculated, so that a feedback control is performed to the irradiating portion to make the brightness fixed. Alternatively, based on a recognition rate upon character recognition within the image taken by the camera, a feedback control is performed to the irradiating portion to make the brightness fixed.Type: GrantFiled: May 12, 2005Date of Patent: July 4, 2006Assignee: Fujitsu LimitedInventors: Masashi Murakumo, Hiroaki Natori, Osamu Ikeda, Yutaka Maruta, Kunihiro Ikeda, Shinji Hidaka, Nobumasa Sasaki, Tamotsu Amamoto, Hiroyuki Nakashima
