Patent number: 6578684Abstract: A driving force transmission device transmits driving force between an outer case made of magnetic substance and inner shaft. A main clutch mechanism, an electromagnetic type pilot clutch mechanism and cam mechanism are arranged between the outer case and inner shaft. The main clutch mechanism transmits driving force between the outer case and inner shaft. The pilot clutch mechanism controls operation of the main clutch mechanism and comprises an electromagnet, an armature and a friction clutch. The cam mechanism amplifies output of the pilot clutch mechanism and transmits amplified output to the main clutch mechanism. The driving force transmission device further comprises a first regulation member and/or a second regulating member. The first regulating member adjusts a clearance between the cam mechanism and the armature to be more than a predetermined distance. The second regulating member adjusts an axial position of the friction clutch.Type: GrantFiled: July 31, 2001Date of Patent: June 17, 2003Assignee: Toyoda Koki Kabushiki KaishaInventors: Masaji Yamamoto, Hiroshi Takuno, Hideyuki Saito, Takashi Hosokawa, Yoshiaki Senga

Patent number: 5423931Abstract: In a method of removing a component from a wiring board to which the component is attached by heat-softenable resin, the improvement is provided of, after softening of the resin by heat and removal of the component, removing residual resin remaining on the board at the location of the component by application of ultraviolet laser radiation having an intensity sufficient to decompose and disperse said residual resin. This can be done without damaging the wiring on the board so that the wiring is re-usable to attach a further electronic component at the same location. Excessive heating of the board can be avoided by measures such as applying a pre-load to the component during softening so that it moves when sufficiently softened, and monitoring the softening.Type: GrantFiled: August 19, 1993Date of Patent: June 13, 1995Assignee: Hitachi, Ltd.Inventors: Hirokazu Inoue, Masahiro Takasaka, Koichi Watanabe, Takashi Hosokawa, Mamoru Sawahata
