Patent number: 8214554Abstract: In one cycle for transferring data, a controller forming a data transfer circuit stores pointer information P_A for periodic transfer and pointer information P_B for non-periodic transfer read from a memory respectively in first and second storage areas. The controller sequentially transfers, to a communication bus, data D_A for periodic transfer and data D_B for non-periodic transfer read from the memory by referring to the P_A and P_B. If transfer by a data length indicated in the P_B has not been completed upon the transfer of the D_B, the controller updates the data length to a data length of the remaining data, and updates an address indicated in the P_B to an address on the memory of the remaining data. In the next cycle for transferring data, the controller reads the remaining data from the memory by referring to the P_B, and transfers the remaining data to the communication bus.Type: GrantFiled: February 24, 2011Date of Patent: July 3, 2012Assignee: Renesas Electronics CorporationInventors: Keisuke Nomura, Tomokazu Kondo, Yousuke Sasaki

Publication number: 20030111628Abstract: An opening end of a concave portion of a bearing holder is crimped to prevent an outer race of a ball bearing from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race. Thus, the number of parts and assembling procedures for an intake air controller are reduced, thereby reducing the manufacturing const thereof. Further, since the bearing stop cover is not needed, the axial length of the bearing holder of a throttle body is shortened, thereby axially compacting the throttle body.Type: ApplicationFiled: February 6, 2003Publication date: June 19, 2003Applicant: DENSO CORPORATIONInventors: Kunio Nanba, Tomokazu Kondo, Takuya Fukitsuke, Kunio Tanaka

Patent number: 6215207Abstract: A torque motor comprises a rotor having a pair of permanent magnet groups, and a pair of stator cores. Each magnet group includes a plurality of plate or rod-shaped permanent magnets arranged in a circumferential direction. The magnet groups are arranged asymmetrically with respect to a rotary axis of the rotor. That is, one magnet group is displaced one-half angle of the pitch angle of each permanent magnet from the symmetric position of the other magnet group with respect to the rotary axis of the rotor. Alternatively, the stator cores are arranged asymmetrically with respect to the rotary axis of the rotor so that a front end of one stator core is displaced from the symmetric position of a front end of the other stator core in the circumferential direction. A cylindrical magnetic cover is fitted on the rotor to cover the permanent magnets circumferentially.Type: GrantFiled: August 21, 1998Date of Patent: April 10, 2001Assignee: Denso CorporationInventors: Jiro Kondo, Tomokazu Kondo, Yuichiro Miura, Hideki Kawamura
