Filed: 1989-10-31
Abstract: PURPOSE:To reduce vibration and a noise at the time of driving a trimmer device by providing a number of revolution switching means for switching the number of revolution of a motor by interlocking with a trimmer switch for operating the trimmer device. CONSTITUTION:When a power source switch 3 is turned on, a motor 1 rotates, and only a main edge vibrates. In this case, a changeover switch 21 of a number of revolution switching means 20 is pressed by a projecting piece 18a of a trimmer switch 18 and closed. Subsequently, when the trimmer switch 18 is turned on, as soon as a trimmer device protrudes, the changeover switch 21 which is pressed by the projecting piece 18a of the trimmer switch 18 and closed is opened. As a result, an impedance connected in parallel to the changeover switch 21 is connected between the motor 1 and a battery 2, a motor voltage drops due to a voltage drop caused by the impedance 22, and the number of revolution of the motor 1 is lowered. The trimmer device 7 is driven by this motor 1 whose number of revolution is lowered, and vibrates by a low vibration frequency.

Title: Aerial wire discharge machining method and device
Inventor: KUNIEDA MASANORI
IPC: B23H7/36
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide an aerial wire discharge machining method capable of finishing work in a short time and with high precision, without giving ill effect to environment. SOLUTION: Wire discharge machining featuring a finishing process of second cut in an atmosphere offers the advantages of giving no trouble in worn electrodes, extremely less machining affected layer as well as better machining reaction than in the case of liquid to provide straightness for a machined face and still narrower gap than in the case of liquid to provide machining into more fine and complicated shape even in using the same diameter wire. Good conditions in the second cut, where the front face of a workpiece is open, is effectively used for improving surface roughness with shallower discharge tracks due to a lower current density following the expansion of an arc column and accelerating highly precise machining while conveniently removing machining debris and applying cooling.  Still, there is no possibility of electrolytic etching on the workpiece in machining because of no use of machining liquid, resulting in ecological machining service.

Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To enable an atomization head main body and a hub member to be easily assembled and disassembled and further to surely hold the hub member in a hub engaging stepped part even at the time of high speed rotation. SOLUTION: The atomization head main body 2 is formed of a metallic material and the hub member 5 is formed of a resin material having moderate elasticity and flexibility. Further a front corner part 3C of the a hub engaging stepped part 3 is formed as an annular hub fall-off stopping part 4 and the hub member 5 is formed so as to have outside diameter size larger than that of the hub fall-off stopping part 4. Thereby the hub member 5 can be fitted in the hub engaging stepped part 3 while subjecting the hub member 5 to elastic deformation by pushing the hub member 5 into the hub engaging stepped part 3. In this state, since the hub fall-off stopping part 4 is formed at a front side of the hub member 5, the hub member 5 is held in a fall-off stopping state by the hub fall-off stopping part 4. Further when rotating at high speed, the hub member 5 is strongly pushed against the hub engaging stepped part 3 by centrifugal force and thereby holding force can be further strengthened.
