Title: Soldering method for leadless chip carrier type ic
Inventor: KANAZAWA JUNICHI
IPC: H05K3/34
Filed: 1988-04-28
Abstract: PURPOSE:To improve reliability of a soldered joint part, by applying a solder paste on a surface area larger than that of a connecting pad, mounting a leadless chip carrier type IC on the solder paste, and soldering the IC by fusing the solder paste. CONSTITUTION:An opening part 23 of a printed circuit board 22 is made larger than a surface area of a connecting pad 7 on a glass-epoxy board 6 and a solder paste 21 is printed, and then a leadless chip carrier-type IC is mounted on the printed circuit board. Soldering is carried out to form soldered joint parts 24. By doing like this, the shapes of the soldered joint parts 24 after soldering are larger due to increase of the amount of the solder as compared to those by a conventional soldering process. The joint strength against external impacts is strengthened and its reliability can be improved by buffering the stress due to the external impacts.

Title: Processing method of registration of character
Inventor: IGARI SHIYOUJI
IPC: G06F17/21
Filed: 1983-06-10
Abstract: PURPOSE:To register a character pattern from a display device having a small number of display lines by converting the character pattern into a binary number and storing the converted binary number in a corresponding position of a dot matrix to register the character pattern. CONSTITUTION:A central processor 21 fetches and executes instructions in a memory 36 sequentially. An external character generator 23 generates a dot pattern previously registered on the basis of a specified code. A hexadecimal number input part 30 divides an (nXm) dot matrix into prescribed bit string units and inputs information constituting a dot pattern in accordance with the position of the divided bit string unit on the dot matrix as a hexadecimal character. The hexadecimal character inputted by hexadecimal number input part 30 is converted into the bit string information of a pattern image and registered in a prescribed position of the external character generator 23 by a pattern registration part 32.
