Title: Lead frame for semiconductor device manufacturing
Inventor: AIBA MASATO
IPC: H01L23/31
Filed: 1988-02-25
Abstract: PURPOSE:To prevent resin from flowing out over a tiebar, by arranging a trench in the tiebar, making resin permeating between the tiebar and a sealing metal mold accumulate in the trench. CONSTITUTION:The title device is constituted of the following; a tab 6, a plurality of inner leads 3, outer leads 9, and lead connecting bridge bodies 10. The inner leads 3 so extend that their tip parts approach each other. The outer leads 9 are linked to the inner leads, and their middle parts are connected with a tiebar 1 which has a trench 4 in the inside. The lead connecting bridge bodies 10 are connected with one-ends of the outer leads 9, and bridge both frames 8. When resin sealing is performed by using a lead frame of this structure, a region defined by mold lines 7 is covered with resin, and resin flowing out from gaps between the leads is once interrupted by resin dam parts 5 between the tiebar 1 and the outer leads 9. However, since fine gaps exist between the tiebar 1 and a sealing metal mold, the resin permeates as far as the tiebar over the resin dam. The resin which has permeated flows into the trench 4 and accumulates therein, so that the resin can be prevented from flowing outside the tiebar 1.

Title: Wall penetration shaped heat pump type air conditioner
Inventor: OOTSUKA YASUYUKI
IPC: F24F1/02
Filed: 1982-03-19
Abstract: PURPOSE:To prevent ingress of rain water by making it possible to open or close the damper of a ventilation port provided in the partition plate of indoor and outdoor units, making the damper free from the tensile strength of the wire in an open state, and allowing the damper to freely open or close depending upon the relation between indoor and outdoor wind pressures. CONSTITUTION:The wire 23 extends by the manipulation of a damper operating switch, and a wire stopper 31 separates from a bushing 30. Thus, the damper 19 assumes a free state, and a bent piece 24 is opened by a gravity moment. In this state, an opening stop metal fitting 32 undergoes control of a stopper 33, and moves between the opening 11 and the stopper 33 under the wind pressure due to an indoor blower and the wind pressure of air flowing to the outdoor blow-off port due to an outdoor blower, to thereby adjust the opening degree. When the wire 23 is tensed by the damper operating switch, and the wire stopper 31 is led in to fix the damper 19, the damper 19 is fixed to a close state. By this procedure, ingress of rain water can be prevented even when one forgets to close the damper.
