Patent number: 11964838Abstract: A printing apparatus includes a printing unit configured to print an image on a sheet; a first exit path from which the sheet with the image printed thereon by the printing unit is discharged while being reversed; a second exit path from which the sheet with the image printed thereon by the printing unit is discharged without being reversed; and a switch member configured to be pivotably arranged so as to switch between the first exit path and the second exit path. The first exit path passes above a pivot center of the switch member, and the second exit path passes below the pivot center.Type: GrantFiled: November 17, 2021Date of Patent: April 23, 2024Assignee: Canon Kabushiki KaishaInventors: Shinya Asano, Takeshi Koda, Toshiro Sugiyama, Waichiro Saiki, Tomohiro Suzuki, Ryo Kobayashi, Tomoyuki Nagase

Publication number: 20200030901Abstract: This small-hole electric discharge machining machine for electric discharge machining of a workpiece by use of a rod-like or pipe-like electrode is equipped with: a first support part for supporting the base side of the electrode; a second support part for supporting the tip side of the electrode; and an intermediate guide device that is disposed between the first support part and the second support part, and guides the electrode. The intermediate guide device is equipped with: a guide part that has an open form and a closed form, and guides the electrode when in the closed form; a driving means for causing the guide part to transition between the open form and the closed form; and a biasing means for biasing the guide part in the closing direction when the guide part is in the closed form.Type: ApplicationFiled: June 12, 2015Publication date: January 30, 2020Applicants: MAKINO MILLING MACHINE CO., LTD., MAKINO MILLING MACHINE CO., LTD.Inventor: Tomohiro NAGASE

Patent number: 10493548Abstract: This fine hole electrical discharge machine applies voltage between a fine hole machining electrode and a workpiece to cause discharge, and machines a fine hole in the workpiece by using energy of the discharge. The fine hole electrical discharge machine comprises: a bendable guide tube having a hollow portion through which the electrode is inserted; and a tube holder that supports the leading end of the guide tube and allows the leading end of the guide tube to be inclined at a desired angle. Thus, even when the workpiece has a complicated shape, like a blisk, having a large number of turbine blades arranged in the circumferential direction, a fine hole can be machined by accurately positioning the electrode so as to orient the electrode toward a target machining point on a surface of the workpiece without involving interference with the workpiece.Type: GrantFiled: March 31, 2015Date of Patent: December 3, 2019Assignee: MAKINO MILLING MACHINE CO., LTD.Inventor: Tomohiro Nagase

Patent number: 9112470Abstract: To keep communication even if a distance between transmission devices is farther and a transmission distance therebetween is longer. A transmission device for alternately performing transmission and reception to/from a communication destination transmission device transmits transmit data to the communication destination transmission device. It receives return data transmitted by the communication destination transmission device after the transmit data reaches the communication destination transmission device.Type: GrantFiled: January 11, 2013Date of Patent: August 18, 2015Assignee: NEC PLATFORMS, LTD.Inventor: Tomohiro Nagase

Patent number: 5947766Abstract: A fitting structure for a connector housing can maintain a stable vibration absorbing function. A flange (14) of a connector housing (10) is provided on the periphery with an outer annular retaining wall (15). A rubber sheet (20) is contained in an interior of the connector housing (10). The connector housing (10) is attached to a body (E) of an engine by means of bolts (B) and nuts (N). When fattening bolts (B) and nuts (N), the rubber sheet (20) is compressed. In a conventional fitting structure, the compressed rubber sheet (20) expands laterally to bulge out of the flange (14). Since the outer annular retaining wall (15), however, serves to limit the lateral expansion of the rubber sheet (20) so that the rubber sheet (20) does not bulge out from the flange (14), it is possible to prevent the rubber sheet (20) from changing its physical and/or chemical nature and to effectively maintain its vibration absorbing function.Type: GrantFiled: November 20, 1997Date of Patent: September 7, 1999Assignees: Sumitomo Wiring Systems, Ltd., Hino Motors, Inc.Inventors: Takeshi Tsuji, Takao Otsuki, Tomohiro Nagase, Hisashi Muraji

Patent number: 5665444Abstract: A tube-shaped film, made of fluorine resin, has a fold-free, smooth, and uniform inner peripheral surface formed thereon by a surface treatment. An apparatus for treating the inner peripheral surface of the tube-shaped film includes a holding device for holding the tube-shaped film on the inner peripheral surface of a cylindrical body with a cylindrical configuration of the tube-shaped film maintained. A treatment device is inserted into the cylindrical body to treat the inner peripheral surface of the tube-shaped film held on the inner peripheral surface of the cylindrical body. The holding device and the treatment device make a uniform linear motion relative to each other and a uniform rotary motion relative to each other.Type: GrantFiled: August 13, 1996Date of Patent: September 9, 1997Assignee: Kurashiki Boseki Kabushiki KaishaInventors: Yosuke Eguchi, Atsuki Wada, Tomohiro Nagase, Yoshiro Hirajima
