Abstract:
PROBLEM TO BE SOLVED: To provide a junction structure of substrates and a joining method which can stably join the substrates and achieve high workability during joining. SOLUTION: A second substrate 2 soldered to a first substrate 1 is elastically bent at a bent portion 9. The first substrate 1 is in contact with a portion where a joint 6 on the second substrate 2 is formed, in a direction along which the bending angle of the bent portion 9 increases. In this state, a first joint 5 on the first substrate 1 and the second joint 6 on the second substrate 2 are joined by soldering. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a socket element allowing easy mounting of a module casing to a carrier element. SOLUTION: An angle of 0-90° is provided between a first face normal 4' of a first surface 4 of this socket element 1 for housing a module casing 3 therein, and a second face normal 5' of a second surface 5 of the socket element 1 formed to be mounted to the carrier element 2.

Abstract:
PROBLEM TO BE SOLVED: To solve the problem wherein solder is hidden behind an electrical element in a conventional flat electric element, it is difficult to detach a defective element and rework is difficult as a result, while the defective element is sometimes detached by manual work using a soldering iron, in order to detach a defective mounted element from a printed board and exchange it, after mounting the printed board. SOLUTION: A coin-shaped battery 20 with leads is provided with bend parts 22a and 23a by bending the respective two leads 22 and 23 in a direction of crossing main surfaces 21a and 21b, in a region farther inside than the edge of the main surfaces 21a and 21b of a coin-shaped battery 21.

Abstract:
PROBLEM TO BE SOLVED: To more facilitate connection work for connecting a light source to an electric board. SOLUTION: When the electric board 48 is slid in the direction of an arrow Y2, pins 61a, 61b, 61c hit the vertexes 109 of cross-sectional semicircles of connection pins 108A, 108B, 108C, the pins 61a, 61b, 61c are inserted into the connection pins 108A, 108B, 108C, and the tip parts of the connection pins 108A, 108B, 108C advance along the vertexes 109 and folded. Then, the solder H is made to flow-in from the other end parts of the connection pins 108A, 108B, 108C, and the connection pins 108A, 108B, 108C and the pins 61a, 61b, 61c are fixed to each other by the solder H.

Abstract:
PROBLEM TO BE SOLVED: To provide a packaging structure of electronic component in which electric characteristics and transmission characteristics are enhanced by reducing parasitic capacitance. SOLUTION: The electronic component packaging structure 1 is provided between two semiconductor elements 163 and 165 mounted on a circuit board 162, and has an AC coupling capacitor 167 for cutting off signals of predetermined frequency or below between these semiconductor elements 163 and 165. In the structure, the AC coupling capacitor 167 is separated partially or entirely from the circuit board 162 and mounted on the circuit board 162. COPYRIGHT: (C)2006,JPO&NCIPI
