Title: Wire bonding method
Inventor: AOKI TSUTOMU
IPC: H01L21/60
Filed: 1988-08-12
Abstract: PURPOSE:To improve the quality of wire bonding by inducing discharge with a discharge voltage higher than a voltage for forming a ball immediately before wiring. CONSTITUTION:After a ball 2 is formed on a metal wire 1 and immediately before a bonding head starts bonding operation, discharge is induced to the ball 2 on the tip of the wire 1 with a voltage higher than a voltage for forming the ball and then wiring is carried out. Thus the wire bonding using a Cu wire can be stabilized and non-bonding of a Au wire can be resolved. With this constitution, the quality of the wire bonding can be improved.

Title: Traveling controller of unmanned vehicle
Inventor: MAEDA TOSHIYA
IPC: G05D1/02
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent deficiencies such as control delay and the like from occurring even when a travel route is made complicated and long by reducing the traffic of travel route information which is transmitted by an unmanned vehicle. SOLUTION: An operating means 1 performs processing that eliminates data showing via points other than junction points and stop points from travel route information (the enumeration of data showing the whole via points) produced by an operating means 53, etc., and processing (compression processing) which adds data showing a branching direction in the junction at need. In this compression processing, the traffic of the travel route information is drastically reduced while the content of a travel route is maintained. A communicating means 55 transmits the gained travel route information after compression to an on- vehicle control station 10 mounted on an unmanned vehicle. Thus, the traffic of the travel route information transmitted to the unmanned vehicle is reduced and control response is improved.  Also, a compression effect in this case becomes larger as a travel route is longer and the number of via points increases. Then, it is possible to prevent deficiencies such as control delay and the like from occurring even if the travel route becomes complicated and large.
