Title: Pattern shape of printed circuit board
Inventor: ONO SHIGEKI
IPC: H05K1/11
Filed: 1990-04-18
Abstract: PURPOSE:To improve solder absorbing effect, to roughen a check pin mounting accuracy of a board checker and to easily manufacture the checker by increas ing the area of part of a plurality of land patterns disposed in close contact larger than the other land pattern. CONSTITUTION:Land patterns 5, 6 are increased in area larger than the other land patterns 2, 3, 4, 7, 8, 9. The patterns 5, 6 are increased larger than the others. Thus, if a solder iron is moved from above to below by a manual opera tion, or if a solder layer is caulked from above to below, excessive solder can be absorbed by the patterns 5, 6, thereby alleviating a solder bridge generation between lands. Its absorbing effect is larger than so-called sacrificing pattern, and a check pin mounting accuracy can be roughened.

Title: Leak testing method
Inventor: SASAKI HISAO
IPC: G01M3/20
Filed: 1986-05-02
Abstract: PURPOSE:To prevent defectives from being shipped without overlooking a leak by pressing fluorocarbon in a package and detecting gaseous fluorocarbon which leaks from the leak opening of the package by a mass spectrometer. CONSTITUTION:The fluorocarbon is pressed in the carbon 5, which is then placed on a heater 4. The pressed-in fluorocarbon becomes gas 6 in a high- temperature state and exits from the leak opening of the package. This gas is detected by the mass spectrometer. Therefore, defectives are prevented from being shipped without overlooking a leak.

In succession, a silicide film is deposited thereon, which is patterned to form a digid line 115. An N<+> impurity layer 109 formed at a contact section between the storage electrode 110 and an N<+> diffusion layer 105a (drain region of a MOS transistor) becomes shallower than the N<+> diffusion layer 105a. Therefore, a PN junction becomes small in area and a leakage charge becomes small.

Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide the driving device for a color liquid crystal display device without increasing the circuit scale by operating the device so that the spacial sampling position of a primary color signal is made to be different from the pixel position of the panel. SOLUTION: Relating to the driving device for a color liquid crystal display device outputting a video signal to a liquid crystal panel 6, the driving device operates the display device so that the spacial sampling position of a primary color signal is different from the pixel position of the panel. Namely, it is preferable that the spacial sampling position of a primary color signal is different from the pixel position of the liquid crystal panel 6 at least in one row from among writing rows for the same horizontal scanning period and both are in coincident with each other at least in one row. Consequently, since the data of two pixels in an odd row and an even row are sampled simultaneously, at least either of the spacial sampling positions is made different from the pixel position of the liquid crystal panel 6.  By this constitution, the circuit scale of the sampling part is not increased.
