Patent number: 11067382Abstract: A three-dimensional coordinate measurement apparatus capable of reducing shaking of a Y carriage and improving measurement accuracy. The Y carriage is supported by two strut members which are across a surface plate and movable in a Y-axis direction. The two strut members include a first strut member having a driving mechanism and a second strut member which moves following the first strut member. A guide portion parallel to the Y-axis direction is formed in the surface plate on a first strut member side. Side surface support members support the first strut member on the surface plate by holding both opposed side surfaces of the guide portion. The driving mechanism includes a roller having an axis perpendicular to a surface plate surface, and the roller is brought into contact with one side surface of the guide portion and rolled to move the Y carriage relatively to the surface plate.Type: GrantFiled: December 20, 2019Date of Patent: July 20, 2021Assignee: Tokyo Seimitsu Co., Ltd.Inventors: Yukio Kanno, Keiichiro Gomi, Takashi Fujita

Patent number: 6104204Abstract: An IC tester is provided which is capable of preventing the temperature of an IC heated to a predetermined temperature from falling during the test. A box-like housing 70 constructed of a thermally insulating material is mounted on a performance board PB. An IC socket SK and a socket guide 35 are accommodated in a space bounded by the box-like housing 70 and the performance board PB. A through-aperture 71 is formed in the top wall of the housing 70 for passing an IC under test carried by a movable rod 60R of a Z-axis driver into and out of the interior of the housing 70. An opening/closing plate 72 is disposed over the housing 70 for movement in a horizontal direction. This plate 72 is adapted to close the through-aperture 71 of the housing 70 when the movable rod 60R is outside of the housing to thereby maintain the interior of the box-like 70 in an almost thermally insulated condition.Type: GrantFiled: May 12, 1998Date of Patent: August 15, 2000Assignee: Advantest CorporationInventors: Hisao Hayama, Toshio Goto, Yukio Kanno

Patent number: 5969537Abstract: In an IC tester of the type in which ICs to be tested are heated by a planar heater plate 50 prior to being tested, a plate-like shutter 70 having windows 71 formed therethrough to expose IC receiving recesses 51 formed in the heater plate 50 is disposed movably over the top face of the heater plate. The arrangement is such that the shutter 70 is shifted by a linear drive source 74 between a position in which the shutter closes the top of the IC receiving recesses 51 and a position in which the shutter exposes the recesses. A controller is provided for actuating the drive source to move the shutter so as to open the IC receiving recesses, whenever a Z-axis drive unit 60 enters into either the operation of dropping off an IC grasped thereby into one of the IC receiving recesses or the operation of picking up an IC from one of the IC receiving recesses.Type: GrantFiled: February 10, 1998Date of Patent: October 19, 1999Assignee: Advantest CorporationInventors: Yukio Kanno, Toshio Goto

Patent number: 5961168Abstract: A pick and place apparatus for picking, transferring and placing an object which is capable of performing picking and placing operations with high stability and high speed without causing a jamming. The pick and place apparatus has a negative pressure source therein and includes a first pressure detector for detecting suction condition in a process for picking up an object by applying a negative pressure from the negative pressure source, a second pressure detector for detecting suction-release condition in a process for placing the object on a predetermined position by releasing the negative pressure, and a controller for controlling an overall operation of the pick and place apparatus to proceed to the next procedure upon receiving a suction detection signal from the first pressure detector or a suction-release detection signal from the second pressure detector.Type: GrantFiled: October 6, 1997Date of Patent: October 5, 1999Assignee: Advantest Corp.Inventor: Yukio Kanno

Patent number: 5812409Abstract: A semiconductor device transporting and handling apparatus is provided which provides for positively grasping and transporting an IC out of a tray loaded with ICs, even if the tray is tilted due to deformations an/or distortions, by the use of a carrier head which is vertically movable through constant strokes. The tilt of the tray is measured by attitude gauging means comprising four sets of optical sensors, the altitude differences of the top surfaces of ICs accommodated in the tray with respect to a reference level are calculated by altitude difference calculating means, and the calculated altitude differences are stored in altitude difference storage means. Once an IC being picked up has been identified, the altitude difference of the identified IC with respect to the reference level is read out, and the position of the tray is moved vertically to conform with the reference level by altitude difference correcting means to insure that the carrier head can pick up the IC.Type: GrantFiled: August 21, 1997Date of Patent: September 22, 1998Assignee: Advantest CorporationInventors: Yukio Kanno, Toshiyuki Kiyokawa

Patent number: 5386633Abstract: A hamburger patty knife is provided which comprises a handle and a transition piece at one end of the handle forming an angle with the longitudinal axis of the handle. A flat plate extends away from the transition piece in a forward longitudinal direction. A blade attachment is provided having a beveled front edge. A structure is for securing the blade attachment to a distal edge of the plate in a removable manner. The beveled front edge of the blade attachment can be used to pick up and turn over a hamburger patty without disrupting the shape of the hamburger patty. Alternatively the blade can be installed in an upside down position which is extremely useful for cleaning dirty grills and pans.Type: GrantFiled: December 27, 1993Date of Patent: February 7, 1995Inventor: Yukio Kanno

Patent number: 5335495Abstract: Described herein is a brake valve which is arranged to prevent low pressure relief actions by relief valves (59A) and (59B) at the time of starting an actuator, for improving the response characteristics and the safety of operation. This brake valve has relief valves (59A) and (59B) and check valves (70A) and (70B) located in coaxial positions, the check valves (70A) and (70B) being arranged to seat on fore end portions of valve seat members (62A) and (62B) when opened, thereby to substantially block the communication of the valve seat members (62A) and (62B) with inlet link passages (56A) and (56B). Therefore, when the check valve (70A) or (70B) is opened at the time of starting the actuator, the valve seat member (62A) or (62B) is supplied with only a throttled flow of hydraulic pressure through the notched portions (73A) or (73B).Type: GrantFiled: May 13, 1993Date of Patent: August 9, 1994Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Hitoshi Sato, Yukio Kanno
