Title: Delustered solder
Inventor: OKAZAKI TASUKU
IPC: B23K35/26
Filed: 1978-10-11
Abstract: PURPOSE:To obtain delustered solder for electronic appliances of specified composition, mainly composed of tin, lead, bismuth, sliver, and indium. CONSTITUTION:This is delustered solder composed of, by weight, 18-45%, of Sn, 5-9% of Bi, 0.05-0.09% of Ag. 0-0.003% of In, and the remainder of Pb and inevitable impurities. In such composition, the light is reflected at random by the delicate crystallization effect of the alloy when solidifying, so that the luster is eliminated, thereby reducing the eye-strain of the inspectors who visually inspect electronic parts such as printed circuits. Also, in this composition, various characteristics are satisfied, such as melting temperature solderability, solder spreading property, and soldering strength. In this alloy, abundant addition of Bi increases the delustering effect, lowers the melting point of solder, but widens the melting region to make brittle; on the other hand, insufficient addition thereof produces only small effect, raises the melting point, and spoils the solderability. A proper quantity  of Ag improves the solderability and lowers the electric resistance; In stabilizes the  solid phase line temperature at a lower side; and Ag-In makes dense the crystallization of solder surface when solidifying and increases the tensile strength.

Title: Vapor deposition method
Inventor: SAITOU GIICHI
IPC: C23C14/08
Filed: 1978-10-13
Abstract: PURPOSE:To sharply shorten the usual heating time of sublimation material, by mixing powdered sublimation substance with powdered alumina having higher sublimation temperature and heat conductivity than the above substance and evaporating by heating. CONSTITUTION:Powdered alumina is mixed with sublimation evaporating material, for example, powdered SnO2 6 and the mixture is charged in the boat 3 in the vacuum vessel 2 and then is heated and moreover, SnO2 6 is evaporated on the glass substrate 5. On this occasion, more rapid heating is able to carry out than the case of exsisting alumina only making alumina as heating medium at the time of heating, because alumina is possessed about 1.5 times of heat conductivity of SnO2 and about 2000 deg.C of high melting point and also is not reacted with SnO2. Also, by the above method, scattering by unexpeted sublimation is able to prevent at the time of rapid heating of only powdered SnO2. Further, powdered alumina left behind as it is because alumina is stable at the sublimation temperature of SnO2.

Abstract: PURPOSE:To make it possible to stably record sharp two-color images free of blurring, by providing a diazonium salt, a basic leuco dye, a coupler compound and a basic substance as a recording layer consisting of one or more layers on base. CONSTITUTION:A diazonium slat, a basic leuco dye, a coupler compound for developing the colors of the diazonium salt and the leuco dye when being heated and a basic substance such as a compound of formula I or II are provided as a recording layer consisting of one or more layers on a base. Thus, the coupler compound for the diazonium salt is used as a color developer for developing the color of the leuco dye, and the basic substance is incorporated, so that the reaction of the diazonium with the coupler compound proceeds easily. Both the diazonium salt and the leuco dye are developed into colors by the coupler compound, and a first recorded image can be easily obtained as a mixture thereof. After the first recorded image is formed, the recording layer is irradiated with active rays. A second thermally recorded image formed in an undeveloped area has a tone clearly distinguished from that of the first thermally recorded image because the diazonium salt has been already decomposed. Thus, a two-color thermal recording material is obtained. In the formulas, each of R1-R3 is an up to 18C alkyl, cycloalkyl or the like.
