摘要:
A CMOS device comprising an N type semiconductor substrate, a P type well region diffused in the substrate, an n-channel MOS transistor formed in the P type well region, and a p-channel MOS transistor formed in the N type semiconductor substrate, and a method for manufacturing the CMOS device. In case the CMOS device serves as a CMOS inverter, the source region of the p-channel MOS transistor, the semiconductor substrate and the well layer constitute a parasitic PNP type bipolar transistor, and the source region of the n-channel MOS transistor, the well layer and the semiconductor substrate constitute a parasitic NPN type bipolar transistor. The product of the current amplification factor .beta..sub.1 of the PNP type bipolar transistor and the current amplification factor .beta..sub.2 of the NPN type bipolar transistor is smaller than 1.

A rear body structure of an automobile having a door in its rear portion comprises a side panel forming a side surface of an automobile body and a rear panel connected to the side panel and forming a rear surface, the side panel being comprised of an outer side panel and an inner side panel. On an outer surface of a rear part of the inner side panel, there is provided a reinforcing member extending vertically of the body, to which an auxiliary reinforcing member, extending between the inner and outer side panels rearwardly of the body, is connected. The auxiliary reinforcing member is connected at its rear portion to an inner end of the rear panel by means of the corner member. As a result, improved rigidity is provided at the rear panel and connection between the same and the side panel without providing any other member which projects into the inside of the automobile.
摘要:
A CMOS FET device having a P well layer diffused in an N type semiconductor substrate, a P channel MOS transistor formed on the N type semiconductor substrate, and an N channel MOS transistor provided in the P well layer, wherein the source of the P channel MOS transistor is made to have the same potential as the N type semiconductor substrate and for the source of the N channel MOS transistor is made to have the same potential as the P well layer, thereby suppressing the operation of a parasitic bipolar transistor whose base is constituted by the N type semiconductor substrate and/or a parasitic bipolar transistor whose base is formed of the P well layer.
摘要:
A commercial article information presenting system includes a shopping basket device and a shopping server communicating with the shopping basket device. The shopping basket device acquires a tag ID from an electronic tag attached to a commercial article put in a shopping basket and transmits the tag ID to a shop server. The shop server stores the tag ID received from the shopping basket device, generates screen data for an itemization screen for indicating a commercial article identifier and a unit price corresponding to the stored tag ID, a total of unit prices. The shop server transmits the screen data for the itemization screen to the shopping basket device.
摘要:
A method and an apparatus for applying the belt-shaped bead filler on the bead core with apex. The method comprises the the step of: rotating a bead core with an apex together with a belt-shaped bead filler; mounting the bead filler on the internal circumferential surface in an approximately cylindrical shape so as to form an overlapping portion; joining at least a part of the overlapping portion; folding up the cylindrical bead filler on both sides of apex and bead core and press-fitting so as to unify them. The apparatus comprises bead supporting means for supporting rotatably abead core with an apex, bead filler guide means having a movable table to mount a starting edge of the bead filler against the internal circumferential surface of the bead core, bead filler cutting means for cutting the bead filler, bead rotating means for rotating the bead core with the bead filler, bead filler joining means for joining at least a part of overlapping portions, bead filler folding-up means for folding up the bead filler and bead filler press-fitting means for adhering the bead filler to the both side faces of the apex and bead core. Thereby, since the belt-type bead filler is folded up after being formed in the shape of cylindrical and the overlapping portion being jointed on both sides of the bead core, it hence becomes possible to enhance the quality of tire by preventing the formation of staggered joint and wrinkles.
