Abstract: In anti-collision support method and apparatus for an automotive vehicle, a deceleration magnitude adjustment manipulation distance which is another vehicular running distance required to carry out a manipulation of an adjustment for a magnitude of the vehicular deceleration which would ordinarily be carried out at a time immediately before the vehicle is stopped is calculated from the vehicular velocity and the relative distance, a vehicular occupant is informed of an approach of the vehicle to the stop target object while the relative distance is shorter than a distance of the vehicle to a deceleration start position which is determined with the calculated deceleration magnitude adjustment manipulation distance taken into consideration and is shorter than a distance of the vehicle to the stop target object.

Abstract: First and second ball forming plates are prepared. The cavities of the first plate and the cavities of the second plate 20 are filled with solder paste, respectively. The first plate and the second plate are placed in a facing relationship to each other and heated to form metal balls each of which corresponds to the total metal components of the solder paste in one cavity of the first plate and one cavity in the second plate. The metal balls are formed in the cavities of the lower plate 10. The metal balls are transferred from the cavities of the first plate to a device on which bumps are to be formed.

Abstract: A semiconductor device including a semiconductor chip sealed with an encapsulating resin. Columnar electrodes are connected to electrode pads of the semiconductor chip, and extend through the encapsulating resin. The columnar electrodes are made from bonding wires and include enlarged outer ends. Solder balls are arranged on the surface of the encapsulating resin and connected to the outer ends of the columnar electrodes. In another example, pin wires are formed by half-cutting bonding wires, bonding one end of each of the bonding wires, and cutting the bonding wires at the half-cut portions.
