Title: Thick film wiring board
Inventor: MORIMOTO RYOICHI
IPC: H05K1/11
Filed: 1988-08-25
Abstract: PURPOSE:To eliminate the electrode crack of a through hole, improve the connection reliability of through hole, and sufficiently exhibit the merit of small-sized wiring board by forming a through hole electrode by printing a thick film of conductive paste in a through hole having a specified diameter arranged on a substrate. CONSTITUTION:A ceramic substrate such as an alumina substrate is used for a substrate 1. At a desired position of the substrate 1, a through hole 2 whose diameter is 0.1-0.2mm is made by, e.g., laser boring process. Conductive paste 3 such as AgPd system and Cu system is spread on the through hole 2 by screen-printing, and a through hole electrode 4 is formed by baking after the paste is dried. The electrode 4 is provided with electrode lands 5 on the surface and the rear of the substrate 1. A penetrating hole 6 is bored at the center of the land. Since the diameter of the through hole is minute, the contraction subsequent to the baking of conductive paste is so little that electrode crack is not caused. Hence, disconnection does not occur on the surface and the rear of the substrate 1. Further the occupied area of the through hole 2 is decreased, so that surplus space generates on the wiring board, and the substrate can be made small.

Filed: 1984-10-08
Abstract: PURPOSE:To make it possible to read both of the entire magnitude of a frequency spectrum having a large peak value and the magnitude of a frequency spectrum having a small level by one picture, by changing over the gain of an IF amplifier in the upper and lower sides of the frequence spectrum. CONSTITUTION:When a detection output component reached a predetermined level, the gain of an IF amplifier is changed over. For example, when a frequency spectrum is displayed, the gain of the IF amplifier is changed over in the upper and lower sides of the frequency spectrum and, at the time of a side desired to be observed in an enlarged state, the gain of the IF amplifier is set to 'large'. In a side wanting to observe the whole of a frequency spectrum having a large peak value, the gain of the IF amplifier is throttled small. Therefore, a necessary part is enlarged on the display surface of CRT and the whole of the frequency spectrum can be also displayed.

IPC: G06F15/16
Filed: 1988-08-29
Abstract: PURPOSE:To execute a sequential user program in a parallel processing system without recording by making parallel programs of the sequential execution type program to automatically generate parallel object codes. CONSTITUTION:Syntax analysis processing 13 takes a source program 11 of FORTRAN as the input and discriminates the presence or the absence of the program by an already prepared pattern matching technique and analyzes the flow of data. The syntax analysis processing 13 first converts the FORTRAN source program to an intermediate language 6. Intermediate processing 14 takes this intermediate language 6 as the input and optimizes and parallelizes it to transform the intermediate language 6. Code generation processing 15 generates an object code 12 to be executed in parallel from the intermediate language 6 transformed by intermediate processing 14. Thus, the time for parallel execution of the object code 12 is shortened.
