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.

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.

摘要:
A semiconductor device employs a lead frame including a die pad (24) and a plurality of leads (25) provided outside the die pad, and is manufactured by sealing the die pad and its periphery by a resin after the die pad is fitted with the semiconductor chip (11). The die pad (24) is formed separately from the main part of the lead frame provided with leads, and is rounded at an entire outermost edge thereof and includes a flat plate shape. This die pad can be either formed rounded with ceramic or resin, or formed in metal and given a rounded edge through honing.

A woofer system for an automotive audio system is provided with a protective cover extending over a section of a vehicle panel which both forms part of a vehicle body and serves as a speaker diaphragm producing acoustic vibrations at audio frequencies. The cover is in a spaced-apart relationship with said section so as not to interfere with oscillation of the section of the vehicle panel while it is oscillating at audio frequencies. The cover has a support extending toward the vehicle panel and surrounding the section. The support is formed with at least one opening for transmitting acoustic vibrations produced by oscillation of the section of the vehicle panel.

A semiconductor device is provided that includes a semiconductor chip and a resin section that molds the semiconductor chip and has a first through-hole. A through electrode that is electrically coupled to the semiconductor chip, extends through the resin section, and extends between a top edge and a bottom edge of an inner surface of the first through-hole. A cavity which extends between planes corresponding to an upper surface and a lower surface of the resin section is formed inside the first through-hole.

A gas treatment device (1), comprising a charging agglomeration part (10) which charges and agglomerates components targeted for collection in gas by utilizing corona discharge, and a filter part (20) which collects the agglomerated components. The charging agglomeration part (10) is disposed on the upstream side, and the filter part (20) is disposed on the downstream side. By this configuration, using the agglomerating functions and precipitating functions of corona discharge and the precipitating functions of filters, ultra-fine particulates can be agglomerated and enlarged. Moreover, the present invention is a gas treatment device that has high performance and low pressure-loss and that is capable of being configured in a compact form factor such that it can also be used as an exhaust gas purification device mounted onboard an automobile.
