Title: Solar cell module and its manufacture
Inventor: YAMADA SATOSHI
IPC: C09J5/00
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain a solar cell module which is excellent in the protective capability of a photovoltaic element and which is not deformed with a temperature change by a method wherein the film thickness of a coating layer is deformed by a definite amount with a definite load at room temperature. SOLUTION: A backside coating layer 101 can change its thickness by 5 to 75% when receiving a load of 2kg per cm<2> at room temperature. When the film thickness changes by less than 5%, the deformation of the coating layer is too small, the layer does not follow an uneven part or the like, a force is concentrated in one point on a recessed part when a module is trampled mistakenly, and there is a danger that the coating layer is broken or that a photooltatic element is broken down. When the film thickens changes more then 75%, the layer follows the uneven part and it becomes thin in the recessed part. Thereby, when the thickness of the original coating layer is not increased, its protective capability is lowered.  Consequently, when the backside coating layer changes by 5 to 75%, it is possible to obtain a solar cell module which is excellent in the protective capability of the photovoltatic element and which is not deformed with a temperature change.

Title: Halftone processing method
Inventor: YOSHIOKA KIYOHARU
IPC: H04N1/405
Filed: 1988-08-31
Abstract: PURPOSE:To obtain a favorable halftone image according to a density level of an input image by providing a plurality of matrixes outputting a plurality of dot patterns for a predetermined density level, and alternately using the dot patterns outputted therefrom. CONSTITUTION:In data of 32 gradation levels from a CCD 1, a level 1 is corresponding to a white side and a level 32 to a black side. For example, with a gradation level 6 a pattern 3 is outputted for all matrix code data, but with an input gradation level 7 the level is divided into 3 and 4 so that a pattern 3 is outputted for matrix code data '00' (SR = 0, SG = 0) or '11' (SR = 1, SG = 1) and a pattern 4 is outputted for matrix code data '01' or '10'. Namely, when input image data of a density level 7 are continuously issued, the density level is divided into 3 and 4 to obtain the halftone gradation thereof. In other words, a gradation with a level of (3+4)/2 = 3.5 is expressed using a 16-gradation pattern, whereby 32 gradation levels are substantially expressed.
