Publication number: 20070169006Abstract: In a system comprising a program of word units, processing of the word unit program for generating output data is completed within a minimum number of execution times by avoiding useless iteration. According to the present invention, a route operation element is regarded as one word, and requirements are defined as a word unit program which defines a relation among words. The route operation element is removed by setting definition equation execution conditions of the route operation element as definition equation execution conditions of words belonging to a basic structure specified by the route operation element when the conditions are established, and structures of the entire system are integrated into one. For an integrated word unit program group (not including the route operation element) of the entire system thus obtained, topological sort is carried out to rearrange word unit program groups in an optimal order. Thus, for example, useless iteration can be prevented.Type: ApplicationFiled: January 29, 2007Publication date: July 19, 2007Inventor: Osamu Arai

Patent number: 7032692Abstract: Locking elements 3d and 3j are provided at an inner member 3 connected to a kelly bar 1, and a locking element bearing plate 6f is provided at an outer member 6. The outer member 6 includes a cylindrical bucket 7 and a grab bucket 8 housed inside the cylindrical bucket 7. When an excavating tool 2 is in its most contracted state, the inner member 3 is rotated forward to lock the locking elements 3d and 3j at the locking element bearing plate 6f, thereby disallowing relative vertical movement of the inner member 3 and the outer member 6. As the excavating tool is rotated by applying a force to the kelly bar 1 along the lifting direction in this state, an excavating operation can be executed while applying a load smaller than the load of the excavating tool 2.Type: GrantFiled: April 25, 2002Date of Patent: April 25, 2006Assignee: Hitachi Construction Co., Ltd.Inventors: Satoshi Nozaki, Takashi Abe, Osamu Arai, Kazuhiro Arai
