Abstract: PURPOSE:To remove the labor of removing resin burrs by forming the gate of a resin mold device astride one or more leads. CONSTITUTION:The gate 15 to be made in the lower mold 12 of a resin mold device is so made as to straddle one or more pieces of leads. Moreover the bottom of the upper mold 11 to block the topside of the gate 15 is kept flat. This way, the width of the gate 15 widens by so forming the gate 15 as to straddle one or more leads 2, and also the gate 15 becomes deeper by keeping the upper mold flat. Therefore, the resin which has solidified inside the gate 15 becomes thick burrs, and the junction strength with the resin which has solidified inside a runner 14 becomes strong. Accordingly, the thick burrs solidify inside the runner 14 and are removed together with the rein adhering to the bottom of the die bar 22, so they never remain as they are adhering to the leads 2. Hereby, the labor of removing the resin burrs can be saved, and the productivity of the semiconductor device improves.

IPC: H05K3/00
Filed: 1987-02-25
Abstract: PURPOSE:To reduce the quantity of data for through hole definition by providing an aperture table (APT) number where shapes of through holes are registered. CONSTITUTION:Display data of the shape and the size of one through hole on each printed board consists of an identification number (ID number) of the through hole, an aperture size code (ASC), and XY coordinates.

Title: Solar drying filter bed

IPC: B01D24/22
Filed: 1980-03-31
Abstract: PURPOSE: To reduce the wear and tear loss of filter sand by unenabling sludge and sand to be mixed together when air cleaning is made by making up the filtering layer portion of fine gravel-coarse sand mixed bed.  
     CONSTITUTION: The filtering layer of a filter tank is made up of a mixture of gravel 9 of a grain size of 20mm or less and sand 10 of a grain size of 0.4mm or more. Thus, when air cleaning is made, the fluidization of filter sand of small diameters is hindered by large-size sand and gravel and the mixed filtering layer, therefore, becomes the same state as in the fixed bed. Also, since small-size sand infiltrate into the large-size sand and gravels to make the intergranular voids smaller, the intrusion of sludge into the sand gravel grains can be prevented within about 5mm from the surface of the filtering layer.
