Patent number: 7299929Abstract: A grain dropping passage constituted below a husking unit(D) serves as a winnowing room(A). A winnowed grain conveyor(1) is provided as the sole conveyor below the winnowing room(A). A winnowing wind blown by a winnowing fan(F) through a blowing room(B) passes through below the winnowed grain conveyor(1) and then rises in the winnowing room(A). The grains mixed with hulls and others are winnowed in the winnowing room(A) so as to be sorted into two kinds: winnowed grains to be received by the winnowed conveyor(1), and the other including hulls to be received by a hull conveyor(2) arranged oppositely to the winnowed grain conveyor(1) with respect to the winnowing fan(F). In this manner, powerful separation can be executed by means of winnowing wind having a large amount and large speed so as to improve a winnowing ability remarkably.Type: GrantFiled: May 28, 2001Date of Patent: November 27, 2007Assignees: Seirei Industry Co., Ltd., Yanmar Agricultural Equipment Co., Ltd.Inventors: Kouji Yokota, Tadashi Hamaguchi

Patent number: 7175509Abstract: Truing of a grinder is performed by irradiating a laser beam onto abrasive grains on the outermost periphery of the grinder from the tangential direction of the grinder. Truing of the grinder for adjusting the number of working abrasive grains and the shape of the abrasive grains involved in the actual machining is performed under a non-contact condition and at highly accurately, thereby enabling highly accurate and highly efficient machining.Type: GrantFiled: January 13, 2004Date of Patent: February 13, 2007Assignee: Itsubishi Denki Kabushiki KaishaInventors: Munehisa Gunjima, Tomoaki Nakasuji, Kouji Yokota

Patent number: 6888472Abstract: An improved programmable timer unit can be incorporated into a remote control management system to actuate loads according a user's defined schedule without relying upon any additional supplementary device for data communication. The timer unit includes an input section for selecting a switch address of any switch employed in the system and a schedule specifying the actuation time and the control code for actuation of the target load or loads. A processor makes up a load management program based upon the schedule and executes the program for control of loads. Thus, the timer unit can alone emulate any one of the switches for controlling loads without relying on additional external device for the data communication.Type: GrantFiled: April 23, 2002Date of Patent: May 3, 2005Assignee: Matsushita Electric Works, Ltd.Inventors: Yuichi Yoshimura, Toshiaki Tokizane, Kouji Yokota

Patent number: 6222293Abstract: A starter comprises a fixing member which has a cylindrical portion and rotation stoppers on the outer wall of the cylindrical portion and is fixed to a bracket so that its movement in a circumferential direction is limited by the rotation stoppers, a mating portion is formed by mating the inner surface of the cylindrical portion of the fixing member with the outer surface of the internal gear of the epicyclic gear reduction unit, and the mating portion is set such that the internal gear slides and rotates with respect to the fixing member when rotation torque applied to the starting output shaft exceeds a predetermined value by machining the end surface of the cylindrical portion of a provisional mating portion formed by provisionally mating the inner surface of the cylindrical portion of the fixing member with the outer surface of the internal gear. Therefore, the breakage of elements of the output transmission system of the starter can be prevented.Type: GrantFiled: March 24, 2000Date of Patent: April 24, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hirohide Ikeda, Kouji Yokota, Kensaku Kuroki
