Abstract: PURPOSE:To decrease the number of times of transfer of a semiconductor device to enable a continuous operation and to practice high-speed bump forming by equipping a stage for heating and adsorbing a semiconductor substrate, a moving a means for moving the stage back and forth and right and left and further rotation-moving the stage, and a bump-forming means for forming a bump in the semiconductor substrate. CONSTITUTION:First, a semiconductor substrate 1b is mounted on a substrate stage 6c. The substrate stage 6c has a structure capable of adsorbing the substrate 1b through an adsorption hole, when vacuum is absorbed from a vacuum- absorbing joint. Also, a heater is inserted into the substrate stage 6c so that the stage can be set to an arbitrary temperature. Then, a hole is formed in the tip of a small-gage metal wire 7 and thereafter the tip is bonded to an electrode 2 to form a bump 3. Subsequently, an NC table 10 on the bonding head 9 side is driven for the purpose of forming the bump. When the bonding head is formed into a small-sized and lightweight one, a high-speed operation is made possible. After the bump 3 has been formed on all electrodes 2, 2... of one semiconductor device, an NC table 12 on the substrate stage 6c side is driven to send the next semiconductor device downward of a capillary 4.

Title: Adjustable arm device
Inventor: HATA MASAHIKO
IPC: F16C11/10
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide an adjustable arm device, which can usually stop an arm and a heavy material at the predetermined position without applying the power from other power source. SOLUTION: Since the torque to be applied to a rotating plate 19 as a high- speed part is remarkably small even in the case where a heavy material is fitted to the tip of an arm 8 or a large force is applied to the tip of the arm 8, rotation of this high-speed part 19 can be constrained by the remarkably small force, or the constrain can be released by the small driving force, and position and height of the heavy material can be easily changed. Furthermore, in usually (when the arm is fixed, since the force of the constraining device such as the energizing force of a spring pushes a constraining piece to the rotating plate 19, when the arms 4, 5 are positioned for fixation, any other power for maintaining this condition is unnecessary.

Filed: 1981-02-26
Abstract: PURPOSE:To realize the accurate measurement of the internal sulphurization state from outside without lifting the contents of a transformer, by flowing the measuring current via a tap switch and comparing the winding resistance at this moment with the winding resistance in the normal state. CONSTITUTION:A tap switch is set in series to the internal winding of a transformer and connected to an external terminal.

Then the winding resistance value of this moment is compared with the winding resistance value in the normal mode before production of a sulfide to presume the sulphurization state of the transformer. In other words, it is decided that the sulphurization progresses considerably in case the winding resistance value is larger than obtained in the normal mode. In such way, the internal sulphurization state of a transformer is accurately measured from outside without lifting the contents of the transformer.
