Patent number: 8490000Abstract: A computer functioning as three-dimensional (3D) computer aided design (3D-CAD) system executes the process for selecting a 3D model of a component from a library. The process includes a step for designating a category of a component; a step for displaying a menu for designating values of category-dependent items representing a specification of the component; a step for narrowing down, on the basis of the designated value, records of a database, in which each record for each component includes the items representing the specification; a step for extracting a possible value of an item with its value being undetermined and accordingly updating a choice(s) selectable via the menu; and a step for determining, to be a 3D model to be loaded from the library, the 3D model of the component uniquely determined after repeating the above-mentioned steps for narrowing-down, extracting and updating for one time or more.Type: GrantFiled: February 27, 2008Date of Patent: July 16, 2013Assignee: Fujitsu LimitedInventors: Yoshihito Okuwaki, Yoshikazu Katou

Patent number: 8249833Abstract: An interference-check-result sorting unit sorts the result of the interference check on an entire 3D model in a 3D-model storage/display unit that is implemented by an overall interference check unit of a model-design verification system into the interference information related to male-screw models and the interference information related to other models. A tapped-hole-diameter changing unit considers that models that interfere with the male-screw models are tapped-hole models, and changes the tapped-hole diameter of the tapped-hole models. A male-screw model/tapped-hole model interference check unit implements checks on the interferences between the respective male-screw models and the corresponding tapped-hole models whose tapped-hole diameter has been changed. And a verification result output unit outputs the result of the verification on the fits between the male-screw models and the tapped-hole models, based on the interference-check results.Type: GrantFiled: May 26, 2006Date of Patent: August 21, 2012Assignee: Fujitsu LimitedInventors: Yoshihito Okuwaki, Yoshikazu Katou

Publication number: 20080076274Abstract: From a component model library 16 having stored therein a three-dimensional component model created for each type of component, a component model to be implemented is created. The component model is incorporated in a three-dimensional printed-board model created based on printed-board information, thereby creating an implemented-printed-board model. A low-component-shape deleting unit 30 deletes a low-component shape having a height up to a specified height from the component models stored in the component model library 16 to reflect the deletion results onto the implemented-printed-board model. A low-component-replacement model creating unit 32 creates and incorporates, based on a component implementation area of a printed board and the specified height, a single low-component-replacement model that replaces a deleted portion of the low-component shape, thereby creating a printed-board simplified model.Type: ApplicationFiled: December 6, 2007Publication date: March 27, 2008Applicant: FUJITSU LIMITEDInventors: Yoshihito Okuwaki, Yoshikazu Katou

Publication number: 20080055778Abstract: A head IC into which a preamplifier and various sensor amplifiers are integrated allows communications such as register setting to the sensor amplifiers even during reading of the preamplifier. Disk device (100) has head IC (1) into which a read/write preamplifier and various sensor amplifiers are integrated, FPC (21), and disk device control circuit section (31). An operation state of head IC (1) and detection values of the sensor amplifiers are set by setting and reading a register value in amplifier/communication control circuit (9). Read signal differential output lines (25) and (26) or write signal differential input lines (27) and (28) are used as communication lines by switching by change-over switches (7) and (32). Communications are performed in a time-shared asynchronous method with communication control circuit (34) and amplifier/communication control circuit (9), and level of the communication signal is set equal to that of a lead signal or write signal.Type: ApplicationFiled: September 16, 2005Publication date: March 6, 2008Inventor: Yoshikazu Katou
