Patent number: 6881013Abstract: A sand pile driving method for making a sand pile which does not cause trouble in terms of strength even at a soft point in the actual ground, and enables secure limitation of the increase in total construction time and total amount of sand. A compaction procedure is a procedure for compacting a granule pile 15 by pressing and rotating the casing pipe 13 downward. This is performed based on thrust force P by which the casing pipe presses a granule pile and a driving torque T for rotating the casing pipe against a granule pile.Type: GrantFiled: July 21, 2003Date of Patent: April 19, 2005Assignee: Fudo Construction Co., Ltd.Inventors: Makoto Otsuka, Osamu Ishida, Hiroki Yoshitomi

Publication number: 20040145839Abstract: A disconnect protection structure for a rotary transformer type resolver includes insulating tube units (611, 612, 613) that house a crossover (60) connecting a rotary transformer output winding (65) and resolver excitation windings (64). A left end (611a) of the protection tube (611) and a right end 613b of the protection tube (613) are secured to the crossover (60). Ends of the insulating tube units (611, 612, 613) other than the secured ends are not secured, and a gap is provided between adjacent insulating tube units. As a result, the unsecured ends are capable of absorbing a force that would otherwise cause the crossover (60) to disconnect from the rotary transformer output winding (65) and/or the resolver excitation windings (64) when the protection tube units (611, 612, 613) and the crossover (60) thermally expand or contract.Type: ApplicationFiled: October 9, 2003Publication date: July 29, 2004Inventors: Taiichi Miya, Makoto Otsuka
