Patent number: 7275567Abstract: A front end of a loop of a wire fed out to a nose (6) by a binding wire feeding mechanism (1) is pinched by a clamp plate (28) of a binding wire clamping apparatus (25) and the wire is pulled back by driving to rotate reversely a feeding motor (13) of the binding wire feeding mechanism (1). When the wire is brought into close contact with a reinforcing bar (S) and a load of the feeding motor is increased to thereby increase a drive current by a constant amount, a control apparatus stops the feeding motor. Thereafter, the binding wire clamping apparatus (25) is rotated to twist the binding wire to bind the reinforcing bar. Since the wire is pulled back and a length of the wire is automatically adjusted in accordance with a diameter of the reinforcing bar, a state of finishing to bind the reinforcing bar is made to be uniform and also an amount of consuming the wire is reduced.Type: GrantFiled: March 7, 2003Date of Patent: October 2, 2007Assignee: Max Co., Ltd.Inventors: Syuichi Ishii, Shinichi Ohkubo, Osamu Itagaki

Patent number: 7248019Abstract: A cordless power tool such as a power staple gun 1 includes a power supply circuit of an electric double layer capacitor 8 and a lithium-ion battery 11. In a standby state, the lithium-ion battery charges the electric double layer capacitor, and at a switch on time, the electric double layer capacitor supplies large current to the motor 5. By combining the lithium-ion battery with high energy density and the electric double layer capacitor capable of discharging large current, it is possible to greatly reduce the size and weight as compared with a case where a nickel-cadmium battery or a nickel-hydrogen battery is used. Besides, since the electric double layer capacitor has a very long lifetime, the running cost can also be reduced.Type: GrantFiled: November 17, 2003Date of Patent: July 24, 2007Assignee: Max Co., Ltd.Inventors: Shinichi Ookubo, Atsushi Matsuoka, Syuichi Ishii

Patent number: 6401766Abstract: A binding machine for reinforcing bars comprising a binding machine body, a bending guide arm, a feed adjustment mechanism, and a twisting mechanism. The bending guide arm is arranged at an end of the binding machine body. A binding wire is sent outside reinforcing bars from the bending guide arm and is formed into a loop, and then a portion of the loop is twisted by the twisting mechanism so as to bind the reinforcing bars. The feed adjustment mechanism adjusts a feed of the binding wire according to one of a diameter of the reinforcing bars and a diameter of the loop of the binding wire wound round the reinforcing bars.Type: GrantFiled: July 21, 2000Date of Patent: June 11, 2002Assignee: Max Co., Ltd.Inventors: Noboru Ishikawa, Osamu Itagaki, Syuichi Ishii
