摘要： PURPOSE:To provide a resin-sealing method, which can surely reduce the occurrence of defective products by exactly controlling the position or the deformation of a lead frame at sealing with resin, and a mold, and a molding device. CONSTITUTION:The deformation of a tab 10a, an inner lead 10b, etc., by the viscous resistance of tablet 7 flowing into a cavity 4 by arranging coils 9a and 9b in the vicinities of the outsides of cavities 4 made in the mating faces of a top force 23 and a bottom force 22, and applying magnetic force to the tab 10a and the inner lead 10b of a lead frame 10, which supports the semiconductor pellet 11 positioned inside the cavity 4 so as to support them. Moreover, the position of the semiconductor pellet 11 inside the cavity is controlled intentionally by applying such magnetic force as to intentionally deform the tab 10a or the inner lead 10b.

摘要： PURPOSE:To improve strength and reliability of a bonded part to a mounting board. CONSTITUTION:A through hole 27 and a cross-shaped groove 28 crossed at the hole 27 as a center are formed on a back surface side of a bonded part of an outer lead 12b protruding from a package 31 of a semiconductor device 30 to a mounting board. For example, a moistened area of the lead 12b with solder in the case of mounting by solder bonding is increased to improve bonding strength and reliability.

摘要： PURPOSE:To reduce the deformation of a lead and to decrease a malfunction, such as a wire short-circuit by forming a section formed thinner than other lead over its longitudinal direction at the outer frame of a lead frame. CONSTITUTION:A lead frame in which part of the outer frame 2 of a lead frame 1 is thinned is prepared. (This thinned recess 9 is treated by etching or the like). Then, a pellet 10 is bonded (placed) by Ag paste on a tab 3. Then, a wire 11 is bonded by thermal press-bonding or the like. Even if a force F as shown in the drawing is applied in this state, since the recess 9 is formed thinner than the other section, the recess 9 is deformed due to its weak strength. If the force F is absorbed by the deformation of the recess 9, the deformation of inner leads 6 can be reduced. Thus, the deformation of the wire 11 upon deformation of the inner leads can be decreased.

摘要： PURPOSE:To detect an obstacle all day and all night by eliminating back ground light in a measuring vehicle for restriction boundary of building. CONSTITUTION:The light source of a light projector 7 is composed of a metal halide lamp so as to project around plane-like projection light LT. One set of receiving system 8 is composed of a wave band selection mirror 81, a transmission filter 82, a shade filter 83, and image receiving cameras 84, 85, and two sets of receiving units 8A, 8B are arranged in slant directions so that visual fields overlap mutually. The image light of an obstacle Q, and a body on the ground R and a light emission body S in a back ground are divided into two by the wave band selection mirror 81, and one is image-received through the transmission filter 82, and the other is image-received through the shade filter 83. In an obstacle detecting portion, the component of the light emission body S is eliminated so as to detect the obstacle by storing image data in a frame memory, abstracting an image component on the projection light LT or the light emission body S in the back ground through difference computing and binary conversion on two sets of the image data, and inverting one side right and left so as to AND-integrate. Workability and the operating efficiency of a measuring vehicle is improved thereby.

摘要： PURPOSE:To specify the roadway kilometers of an obstacle by providing an optical unit, an obstacle detection section, a vibration detection section, and a range pulse generator, correcting the range interval data calculated by an interval calculation section calculating the range interval against the construction gauge and the vibration quantity data, and compiling the measured data. CONSTITUTION:Image data of both CCD cameras 64, 65 of an image receiving system 6A are stored in frame memories (MEM) 92a, 92b. Nonluminescent ground objects on the background are removed from both data by a differential circuit 93a. An image receiving system 6B is likewise differentially calculated, the data are inverted on the right and left by right/left inverting circuits 94, the data are converted into binary data by binary circuits 95a, 95b, the background is removed, and an obstacle Q is extracted. The address data of the MEM for the obstacle Q are corrected, and the range against the construction gauge is calculated. The vibration quantity data are read out from a vibration quantity detection section 7, the correction data are read out from a ROM 103, and the vibration quantity data are corrected by a vibration correction section 102. Roadway kilometers are calculated by a roadway kilometer calculation section 105 and added to the measured data by a data compilation section 104, and the added value is outputted to an output section 12.
