Title: Soldering method of semiconductor package
Inventor: NAGAYAMA CHIKAKO
IPC: H05K3/34
Filed: 1990-11-09
Abstract: PURPOSE:To surely form fillets on the lead end surfaces, by a method wherein cream solder of a previously determined length is printed at the positions on electrodes, where leads are connected, which leads are more outer than the lead tips when a semiconductor package is mounted, viewed from the package center. CONSTITUTION:Cream solder 6 is printed at locations more outer than the positions of lead end surfaces 5 of a semiconductor package 3 mounted on electrodes 2 of a substrate 1. The package 3 is directly put not on the cream solder 6 but on the electrodes 2. When the substrate 1 on which the package is mounted is heat-treated, the fused solder 7 fits easily to the electrodes 2 and stretches. When the solder reaches leads 4, it comes together between the electrodes 2 and the leads 4, and fillets 8, 9 are formed. Hence the fused solder 7 exists initially outside the lead end surfaces 5, passes through the lead end surfaces 5, and flows along the leads 4, so that the solder is draped also with the lead end surfaces 5 where the solder-plated layer does not exist, and the fillet 8 is surely formed.

Title: Yawing momentum control devce for vehicle
Inventor: NAITOU MOTOHIRA
IPC: B62D6/00
Filed: 1994-12-08
Abstract: PURPOSE: To ensure shift responsiveness during swiching of steering by providing a steering speed detecting means and a correcting means to correct a feedback gain to be smaller as a signal detected by the steering speed detecting means is greater. CONSTITUTION: A steering speed detecting means and a correcting means to correct a feedback gain to be smaller as a signal detected by the steering speed detecting means is greater are provided. To match a real yawing momentum to a target yawing momentum, a feedback controlled variable is set smaller as a detected steering speed value is larger. The feedback gain is set smaller prior to the rising of the target yawing momentum, so that a controlled variable to match the real yawing momentum arising really in delay to the target yawing momentum is delayed, compared with that when the feedback gain is not corrected, and the controlled variable at the begining of steering is a smaller value. As a result, when a steering speed is slower, e.g. during shift to turn, turning-around and steering performances are kept.
