Title: Resin molding method and molded material
Inventor: KUBO HIROSHI
IPC: H01L21/56
Filed: 1986-07-09
Abstract: PURPOSE:To enable a high-reliability semiconductor device to be obtained with good yield, by disposing air vents on a plurality of sides of cavities so that voids can be prevented from being formed inside a molded resin, together with avoiding short filling of resin. CONSTITUTION:A melting resin 10 is injected as shown by arrows of full lines in process of resin molding. Air existing in cavities of a molding metallic mold is exhausted from air vents of the molding iron mold as shown in two-dot chain lines and besides from air vents 9 formed on respective dams 5 of a lead frame 1. Because the air is thus exhausted from three sides of these air vents of the cavities shaped in rectangles, the air is effectively drawn out with out remaining in the cavities. Resultantly voids are hardly generated inside a package 8, and the recessed parts or the like are prevented from being generat ed on the surface of the package 8 due to the remaining foams. Thus, short filling of resin also hardly occurs.

Title: Method and device for ultrasonic flaw detection for square material
Inventor: INAZAKI KOUJI
IPC: G01N29/38
Filed: 1981-10-07
Abstract: PURPOSE:To permit flaw detection with high accuracy by changing an ultrasonic flaw detecting area at each fluctuation in the sectional size or shape of square steel by following up to  said fluctuations even when said size and shape fluctuate. CONSTITUTION:The transmission pulse output Ta from a signal transmission part 10 is converted to ultrasonic waves by a probe (a). Said ultrasonic waves are transmitted toward square steel 1. The ultrasonic waves reflected from the steel 1 are received by the probe (a), where the waves are converted again to an electric signal. The signal is amplified up to a prescribed value by a signal receiving amplifier 13, whereby R signals, that is, signals of a transmission echoes (T), surface echoes (S), bottom echoes (B1, B2...) are obtained. Wall thickness signals E1, E2 are obtained by a generating part 14 for wall thickness signals by the use of said receiving signals R and the S echo gate Gs1, B echo gate Gs2 of said generating part 11. The signals E1 and E2 obtained here indicate the sectional size of the square steel, and said size is measured by counting said signals with a counter 16 via a flip-flop circuit 15, etc. A control part 17 for flaw detection gates determines the beginning and end points of the flaw detection gate by subtracting the predetermined depth Wa of the dead zone in the surface layer part and the thickness Wb of the dead zone in the bottom layer part from the size value of the wall thickness of said square steel. Thus the flaw detection gate is controlled always to the specified depths of the dead zones in the surface and bottom layer parts in accordance with the wall thickness size of the square steel.
