Patent number: 7777874Abstract: A noncontact form measuring apparatus emits a laser beam L. In the apparatus, a prism bends the laser beam into an X-axis direction, so that a Z-axis displacement of an objective optical system is converted by the prism into an X-axis displacement on a measurement coordinate system. A movement of an X-axis stage is converted into a Z-axis displacement on the measurement coordinate system. The apparatus moves an internal gear as a measurement object and the prism, reads X, Y, and Z coordinates at each focal point, and measures a three-dimensional form of inner teeth of the internal gear. The apparatus may translate the internal gear in a Y-axis direction, to measure a partial form of the inner teeth. The apparatus may turn the internal gear in an angular ?-direction, to measure a whole circumferential form of the inner teeth.Type: GrantFiled: April 23, 2008Date of Patent: August 17, 2010Assignee: Mitaka Kohki Co., Ltd.Inventors: Katsushige Nakamura, Katsuhiro Miura

Patent number: 6501470Abstract: A section deriving unit (10) derives a section to which a digital input value DIN belongs and outputs a section number IVN, and a computation parameter output unit (20) outputs a computation Parameter CPA corresponding to IVN. A computation unit (30) performs a given computation based on DIN and CPA and outputs the result of the computation as a digital output value DOUT. Any DIN-DOUT conversion characteristic that the user requires can be obtained by setting a delimiter information storage unit (12) and a computation parameter storage unit (22) as appropriate. The computation unit (30) could, for example, perform a calculation DOUT=amXm+am−1Xm−1+ . . . a1X+a0, based on computation parameters am to a0. This look-up table device can be used for gamma compensation or depth cueing conversions.Type: GrantFiled: January 19, 1999Date of Patent: December 31, 2002Assignee: Namco, Ltd.Inventor: Katsuhiro Miura

Patent number: 6489967Abstract: When displaying a scene on a display screen in which a translucent object and a background object of the translucent object overlap in a virtual space, data of a background object stored in a storage device is continuously read, a translucent calculation is performed between data of the background object and data of the translucent object overlapping the background object, and data of the result of the translucent calculation is continuously written into the storage device. Here, read of the background object data and the translucent calculation, or the translucent calculation and write of data of the translucent calculation result can be simultaneously performed. Further, the translucent calculation can be divided into a plurality of calculations, and the plurality of calculations can be performed simultaneously. With this method, translucent calculation can be performed in a short time.Type: GrantFiled: September 1, 1999Date of Patent: December 3, 2002Assignee: Namco LimitedInventor: Katsuhiro Miura

Patent number: 6429874Abstract: It is an object to provide an image generating apparatus and method which can perform a high-quality translucence process with reduction of the hardware scale and processing load. The translucence process is performed according to a first translucence information OPt used for performing the translucence control with respect to the respective portions of an object and a second translucence information OPm used for performing the translucence control with respect to the entire object. The translucence control according to OPm is invalidated with respect to a portion of the object that is judged to be opaque according to OPt, that is, to be OPt=1. For example, the translucence control may normally be carried out according to the relational expression of OPp=OPm×OPt. On the other hand, when a switching flag SFL is 0, OPp is fixed at 1 or the translucence process is omitted, with respect to the opaque portion.Type: GrantFiled: September 14, 1998Date of Patent: August 6, 2002Assignee: Namco Ltd.Inventor: Katsuhiro Miura

Patent number: 6354943Abstract: An objective is to provide a game system and information storage medium which can improve the operating rate of a game center and realize a more effective management therein. The game system includes a host machine and a plurality of game machines. The host machine is designed to detect the current time or date and to perform allocation of games to the game machines G1 to G9 based on the detected time or date. Transfer data for a player to play a game by means of each of the game machines is then transferred to each of the game machines according to the allocation. A manager of the game center sets schedule data representing how the allocation is carried out according to the time or date. The allocation of games to the game machines may depend on time periods, date or a traffic line of players. Adult games may be set to be played only in the nighttime. Game sound volume and screen brightness may be changed and set based on the time or date.Type: GrantFiled: July 31, 2000Date of Patent: March 12, 2002Assignee: Namco Ltd.Inventor: Katsuhiro Miura
