Patent number: 7869622Abstract: Within a prioritized mode selection dialog, either a measurement accuracy prioritized mode or a measurement speed prioritized mode is selected. If the measurement accuracy prioritized mode is selected, then processing for entering a tolerable amount of movement is executed. Then, a relative movement speed of a CCD camera to a measurement stage is calculated from the entered amount of movement. Finally, image information is captured at a lower speed than the calculated relative movement speed to execute image measurement. If the measurement speed prioritized mode is selected, then processing for entering a relative movement speed is executed, and image information is captured at the entered relative movement speed to execute image measurement.Type: GrantFiled: May 31, 2006Date of Patent: January 11, 2011Assignee: Mitutoyo CorporationInventors: Sadayuki Matsumiya, Koichi Komatsu

Patent number: 7268894Abstract: An image measuring method comprises making no stop of an imaging means relative to a measurement stage at measurement positions (MP1-MP3), and capturing instantaneous images to acquire information required for measurement. A first direction to a measurement position (MP1) to be measured next and a second direction from the measurement position (MP1) to a next measurement position (MP2) form an angle therebetween. If this angle exceeds a certain angle, an overshoot path is formed at a location beyond the measurement position (MP1) in the first direction. The larger the angle formed between the first direction and the second direction, the lower the measurement speed at the measurement position (MP1) is made.Type: GrantFiled: May 22, 2006Date of Patent: September 11, 2007Assignee: Mitutoyo CorporationInventors: Sadayuki Matsumiya, Hirato Sonobe, Koichi Komatsu

Patent number: 6816609Abstract: In this machine and method for measuring a plurality of workpieces, images of a plurality of workpieces placed on a stage are captured using a CCD camera. The images are processed by a computer system whereby the workpieces are measured. A computer system divides a measurement area on the stage into matrix such that each cell in the matrix is correlated to each workpiece. Then, the system sets a measurement program for each cell. Using the cells, the computer system determines a measurement order and whether or not to execute measurement. Measurement data for each cell is output to a CRT.Type: GrantFiled: June 9, 2000Date of Patent: November 9, 2004Assignee: Mitutoyo CorporationInventors: Masato Shimizu, Koichi Komatsu

Patent number: 6490541Abstract: An apparatus for visual measurement is provided, which can measure a plurality of portions on a work at a high speed. An image pick-up system (3), including an optical system (5, 6) and a CCD camera (4), picks up an image of a work (2) to obtain image data. The image pick-up system (3) is driven in the Z axial direction by a driving motor (7). A displacement of the image pick-up system (3) in the Z axial direction is measured by a scale counter (8). A computer (10) reads image data from the CCD camera (4) and a Z value from the scale counter (8) into respective memories (11, 9) with a constant time interval. A contrast arithmetic unit (12) computes a contrast value at each of a plurality of different regions of image data obtained at each z axial position by the image pick-up system (3). It determines a measure for the each region based on the position of the image pick-up system (3) in the z axial direction when the contrast value comes to the maximum in the each region.Type: GrantFiled: June 19, 2000Date of Patent: December 3, 2002Assignee: Mitutoyo CorporationInventors: Kozo Ariga, Koichi Komatsu

Patent number: 5975232Abstract: A power assisted steering apparatus for a vehicle has a driving source and an actuator for the vehicle's steering mechanism, to power assist the steering operation. The driving source, such as an engine, continuously drives a pump. A working passage is arranged so that working oil discharged from the pump is introduced into the actuator. A check valve is disposed in the working passage, between the actuator and the pump so that the working oil flows only one way to the actuator. An accumulator is connected to the working passage, between the check valve and the actuator to maintain a predetermined pressure in the working passage. A regulator is connected to the working passage, between the pump and the check valve to regulate flow to the actuator. When the pressure within the working passage reaches the predetermined pressure, the working fluid is dumped to a reservoir, bypassing the check valve, the accumulator, and the actuator.Type: GrantFiled: January 7, 1997Date of Patent: November 2, 1999Assignee: Unisia Jecs CorporationInventors: Koichi Komatsu, Tatsuyoshi Maruyama, Tadaharu Yokota, Toshinori Aihara, Norihiro Saita

Patent number: 5174338Abstract: A pressure control valve unit includes a valve housing formed with a valve bore. The valve housing is also formed with an inlet port, a drain port and a control port. A valve spool is disposed in the valve bore for selectively establishing fluid communication between the control port and the inlet port, and between the control port and the drain port. The drain port is connected to a first drain path which selectively establishes and blocks fluid communication between the drain port and a working fluid source and to a second drain path which normally connect the drain port to the working fluid source. A flow restricting orifice is provided in the second drain path for constantly permitting limited flow rate of the working fluid from the drain port and the working fluid source. The flow restricting orifice generates damping force for damping surge pressure.Type: GrantFiled: April 8, 1991Date of Patent: December 29, 1992Assignee: Atsugi Motor Parts Company, LimitedInventors: Tadaharu Yokota, Koichi Komatsu

Patent number: 5127312Abstract: A power-assist device for an automotive steering system employs an easy-to-assemble hydraulic pressure control valve to compensate for differential forces on opposite sides of an actuating piston in an unbalanced hydraulic cylinder. The piston divides the cylinder into first and second working chambers which are each connected to a hydraulic pump and a return reservoir via first and second spool valves, respectively. The spool valves are actuated axially by a torsion bar connected to the stub shaft of the steering column, so that they reciprocate axially within bores through the valve body as the steering wheel is turned back and forth. Lands on the spool valves oppose slightly larger lands the bores to define orifices which control the rates of hydraulic supply and drain to and from the working chambers of the cylinder.Type: GrantFiled: July 24, 1985Date of Patent: July 7, 1992Assignee: Atsugi Motor Parts Co., Ltd.Inventors: Seiji Uemura, Koichi Komatsu

Patent number: 4953416Abstract: A power-assist device for an automotive steering system employs spool valves with different external diameters to control the fluid pressure in smaller and larger area chambers of a pressure control valve which controls pressure in an unbalanced cylinder device. The different size of spool valves are disposed within different sizes of bores formed through a housing of the pressure control valve for defining wider fluid path area for introducing larger amount of working fluid into the smaller area chamber in comparison with that for the larger area chamber and narrower fluid path for draining the working fluid in the smaller area chamber for lower drainage rate in comparison with that for the larger area chamber.Type: GrantFiled: August 21, 1985Date of Patent: September 4, 1990Assignee: Atsugi Motor Parts Company LimitedInventor: Koichi Komatsu
