Patent number: 8560748Abstract: An interrupt control circuit asserts a remap signal in response to an interrupt request from a low-speed slave to a processor, and reads information stored in an information register of the low-speed slave. The interrupt control circuit writes the read information into a buffer exclusively for interrupt processing. A switch circuit supplies a read access request which is a request from the processor to the information register to the low-speed slave during negation of the remap signal, and supplies the read access request to the buffer via the interrupt control circuit in order to read the information from the buffer during assertion of the remap signal. By accessing to the buffer exclusively for the interrupt processing instead of the information register in response to the read access request from the processor, the interrupt processing time may be shortened.Type: GrantFiled: March 23, 2011Date of Patent: October 15, 2013Assignee: Fujitsu Semiconductor LimitedInventors: Takayuki Kume, Yousuke Nanri

Patent number: 8007213Abstract: When a horizontal shaft and a piston are caused to travel to a first side with a gear coupling engaging, the revolution of the piston is designed to be restricted by meshing a spur gear with an internal gear fixed to a main body of a horizontal swivel part. On the other hand, when the horizontal shaft and the piston are caused to travel to a second side and the gear coupling thus disengages, the horizontal shaft and the piston are designed to be revolved in an integrated manner by meshing spur gears respectively with other spur gears. When the horizontal shaft and the piston travel from the first side to the second side, the spur gear is designed to be spaced away from the internal gear after the spur gear meshes with the spur gear.Type: GrantFiled: December 12, 2007Date of Patent: August 30, 2011Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Mutsumi Yoshikawa, Takayuki Kume, Keiji Tomimatsu, Hiroyuki Yamamura, Isamu Takehana

Patent number: 7882608Abstract: In a case where the load is not smaller than the predetermined value, the positioning is not completed even when it is determined that the movable body is moved to the position supposed to be the target position, then the movable body is moved to a retry starting position different from the position supposed to be the target position, subsequently a retry operation is performed for moving the movable body from the retry starting position to the position supposed to be the target position, and consequently the positioning is completed when the load becomes smaller than the predetermined value after the retry operation is performed for a predetermined number of times.Type: GrantFiled: December 12, 2007Date of Patent: February 8, 2011Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Takayuki Kume, Hiroyuki Yamamura, Katsuhiro Fujimoto
