Title: Driving method of grinding machine by 3-phase induction motor
Inventor: TAMURA KATSUAKI
IPC: H02P21/05
Filed: 1983-03-16
Abstract: PURPOSE:To reduce the adverse influence due to electromagnetic vibration of a motor by driving a spindle shaft by coupling the motor in a delta connection at the grinding time of high load with much machining amount and in a star connection at the low load time with less machining amount. CONSTITUTION:A spindle shaft of a grinding machine is driven by a 3-phase induction motor which s switched in 3-phase windings between a delta connection and a star connection. When the machining amount increases at grinding time of high load, the terminals of windings X and V, Y and W, U and Z are coupled in a delta connection for large torque, and when the machining amount decreases at grinding time of low load, the terminals of X, Y, Z are coupled in a star connection for small torque, and the motor is operated. Accordingly, at low load time, the magnetic vibration of the motor can be set to 1/3<1/2> of that at the delta connection time to reduce the electromagnetic vibration, the influence to the ''fringe pattern'' of the grinding surface, thereby improving the accuracy of the finished surface.

Title: Conductive paste
Inventor: MURATA YASUHIRO
IPC: H01B1/20
Filed: 1989-02-23
Abstract: PURPOSE:To enable the paste in the title to secure its stable contact condition even if a high-density current is applied by coating the surface of conductive power with a conductive material melting at not less than a given temperature. CONSTITUTION:The surface of conductive powder 5 is coated with a conductive material 6 which melts at not less than a given temperature. When conductive paste is applied onto a substrate 1 and then a chip 2 is placed thereon to be bonded, the conductive powder 5 exists independently in each of resin 3 and a solvent 4 in a condition established before the conductive paste is dried, so that it is set in its insulated condition. When the conductive paste is heated and dried at a temperature ranging from about 100 degrees Centigrade to about 200 degrees Centigrade and the wire bonding is done at a temperature ranging from about 200 degrees Centigrade to about 300 degrees Centigrade, the solvent 4 is volatilized as a result of treatment by heating and drying, causing the resin 3 to cure and contract. Thus, the conductive coating material 6 melts with heat applied during the process of treatment and therefore a conductive condition can be secured over a large contact area for permitting avoidance of any adverse effect on the paste, due to heat generated by contact resistance.
