Filed: 1995-04-21
Abstract: PURPOSE: To save energy consumption of an electromagnet through non-overload of guide roll and removal of lever device, by compensating for insufficient and excessive supporting force with a guide roll up to the load limit value, and then connecting as a load the electromagnet when such supporting force becomes larger than the load limit value. CONSTITUTION: A magnet plate body 1 having a permanent magnet 2 and an electromagnet 3 is provided at both sides of a vehicle. The shaft of the guide rolls 4 and 5 at the upper and lower sides or the guide rail 7 is fixed and coupled to the magnet plate body 1 and thereby an almost constant gap L is generated between the permanent magnet 2 and a long-length stator 6 in the rail side, and between the electromagnet 3 and the long-length stator 6. The guide rolls 4 and 5 rotate at the upper and lower sides of the guide rail 7. The permanent magnet 2 is attracted by the long-length stator 6 to support the vehicle 9 via the magnet plate body 1 and a spring device 8. Load on the vehicle is measured with the spring device 8 via a pressure sensor.  When the upper and lower guide rolls 4, 5 reach the load limit value, the electromagnet 3 is additionally connected with a control circuit and thereby the power consumption can be saved.

Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To simplify an operation of mounting a package substrate to a circuit board by mounting the first plane of a connector to a conductive trace by thermoplastic resin bonding and mounting the second plane of the connector to the conductive pad of the circuit board by thermoplastic resin bonding in the same manner. SOLUTION: The first plane of the sphere of a connector 302 is connected to a conductive trace 312 by thermoplastic resin bonding, and the second plane of the sphere of the connector 302 15 connected to the conductive pad 310 of a circuit board 306 by thermoplastic resin bonding in the same manner. At that time, a preferable contact area for the conductive pad 310 and the conductive trace is decided by insulating material layers 316 and 314, respectively. Since a thermoplastic material 308 as thermoplastic resin does not require flux for cleaning the surface prior to bonding and no residue is left on the circuit board 306, an operation of mounting a package substrate 304 on the circuit board 306 is simplified.
