Patent number: 6595149Abstract: A seedling-growing sheet (1) is in the form of a laminate body (2) consisting of a band-like support member (3) and a porous sheet body (4) laminated on the support member (3). A large number of receptacles (6) for housing rice seeds (15) are formed in the sheet body (4) of the laminate body (2). These receptacles (6) are arranged apart from each other in the longitudinal direction of the support member (3). Formed in the laminate body (2) are cutting perforations (8) consisting of a large number of cut lines (9) along which planting pieces (10) each having at least one receptacle (6) are cut away from the laminate body (2). These cutting perforations (8) are arranged apart from each other in the longitudinal direction of the laminate body (2).Type: GrantFiled: August 20, 2002Date of Patent: July 22, 2003Assignee: Honda Giken Kogyo Kabushki KaishaInventors: Tsuneo Onodera, Yoshiaki Watanabe, Katsuhisa Ichikawa, Yasumi Fukuzumi, Shigetaka Isoyama

Patent number: 6564889Abstract: A crawler vehicle comprises a body frame and an auger mounted to the body frame at a front portion thereof, the body frame being mounted to a rear portion of a crawler frame via a pivot shaft to allow the crawler frame carrying a crawler belt to swing vertically. The pivot shaft is located forwardly of a lower idle wheel rotatably mounted to the crawler frame. Positioning of the pivot shaft forwardly of the lower idle wheel allows the auger to move downward even when a front portion of the crawler belt is lifted. This causes the auger to move downward regardless of new snow or hard snow, enabling the auger to carry out snow-removing operation in a highly efficient manner.Type: GrantFiled: July 20, 2001Date of Patent: May 20, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Nobuo Yamazaki, Katsuhisa Ichikawa

Patent number: 6543548Abstract: A working vehicle 1 includes front wheels Wf steered by a steering wheel 8, and rear wheels Wr driven through a transmission system T incorporating static hydraulic pressure type continuously variable transmissions. A speed change operating device M for controlling speed change of the transmission system T accelerates or decelerates right and left rear wheels Wr at same rotating speed by operation of a change lever 10, and also generates a difference in rotating speed between the right and left rear wheels Wr by operation of the steering wheel 8. The steering characteristic on the basis of operation of the steering wheel 8 varies depending on the vehicle speed set by the change lever 10, so that an appropriate steering characteristic may be obtained if the vehicle speed is changed.Type: GrantFiled: May 17, 1995Date of Patent: April 8, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsuhisa Ichikawa, Masakatsu Kono, Kazunari Iriki, Tsuyoshi Kawabata, Kenji Kuroiwa, Tsutomu Inui

Patent number: 5901791Abstract: A working vehicle includes an engine in the rear of a passenger seat, and a working machine vertically movably disposed in the rear of the engine, wherein an upper end of the working machine which is lifted to the highest position is set lower than an upper end of the engine. As a result, a ventilation in the vicinity of the engine is improved and a cooling effect of the engine is enhanced. Also, a maintenance of the engine can be conducted without being interfered by the working machine. Further, with this arrangement, a center of gravity of the working machine is low, thereby enhancing a stability of the working vehicle, and a driver or a passenger of the vehicle can visually check backward much easier.Type: GrantFiled: November 4, 1997Date of Patent: May 11, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsuhisa Ichikawa, Masakatsu Kono, Kazunari Iriki, Tsuyoshi Kawabata, Kenji Kuroiwa, Tsutomu Inui

Patent number: 5850886Abstract: Left and right driven wheels are connected to a pair of continuously variable transmissions and independently driven. The driven wheels are increased or decreased in speed at the same rotational numbers by operation of a change lever so as to move a vehicle forward or backward. When a steering angle of a steering wheel exceeds a predetermined value, an inner wheel speed during turning of the vehicle is decreased and an outer wheel speed during turning of the vehicle is increased so as to turn the vehicle. If the steering wheel becomes greater than the predetermined value during forward running of the vehicle at a low speed, the inner driving wheels stop and the vehicle does a stationary turn. However, during forward running at a high speed or backward running of the vehicle, even if the steering wheel becomes greater than the predetermined value, the vehicle does not do a stationary turn.Type: GrantFiled: July 18, 1996Date of Patent: December 22, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masakatsu Kouno, Katsuhisa Ichikawa, Masahide Shinokawa, Nobuo Yamazaki
