Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To avoid abrupt change of ink pressure due to momentum of the ink in a flexible ink tube by assembling a diaphragm having flexibility in an ink chamber of a print cartridge in the case of scanning the carriage across a medium. SOLUTION: To alleviate influence of abrupt change of ink pressure due to acceleration or deceleration of a scanning carriage, there are flexible parts (e.g. rubber) identified as a diaphragm 76 at walls of ink chambers 72, 73. The diaphragm 76 is slightly bent to outside upon abrupt rising of ink pressure to absorb rising of introducing ink pressure. Contrarily, the diaphragm 76 is bent to inside into the chambers 72, 73 to absorb abrupt rise of negative force in the ink. Characteristics of the diaphragm 76 are empirically decided based on characteristics of its ink jet printer by considering scanning acceleration, and sizes of the chambers 72, 73.

Abstract: PURPOSE:To completely remove gallium of the rear surface of a substrate without damaging the front surface of the substrate by dipping the substrate together with a supporting base in hydrochloric acid heated to a specific temperature, removing the substrate from the base, and purifying the rear surface of the substrate. CONSTITUTION:A supporting base 1 of molybdenum adhered with a cadmium telluride substrate 3 by gallium 2 is dipped in hydrochloric acid 7 heated to a temperature near 50 deg.C, at which mercury is not evaporated from cadmium mercurytelluride grown on the substrate 3, higher than the melting point of the gallium 2. Then, the gallium 2 is converted from solid to liquid due to the temperature higher than its melting point, and simultaneously dissolved in the acid 7 by chemical reaction. Accordingly, the substrate 3 is peeled from the base 1 in several seconds. The gallium adhered to the rear surface of the substrate 3 is clearly dissolved by the chemical reaction with the acid, thereby providing cleaning effect of the rear surface of the substrate 3. Thus, the rear surface of the substrate 3 is completely purified, and not brought into contact with the front surface of the substrate 3. Therefore, the surface is not damaged, and it can safety be removed from the base 1.

Abstract: PURPOSE:To obtain a photovoltaic apparatus having a very efficient heterojunction by forming a comb-shaped current collecting electrode and making the interval of the fingers of the current collecting electrode smaller than, at least, the diffusion length of minority carrier in crystalline silicon. CONSTITUTION:A comb-shaped electrode 19 having a bus bar 19a and fingers 20 extending from the bus bar is, for instance, arranged on a p-type amorphous silicon 18, and an interval D of the fingers 20 of the current collecting electrode 19 is narrowed. Current collection is made possible without using a transparent electrode, if the interval D of the current collecting electrode 19 is made smaller than the diffusion length of minority carrier in n-type single-crystal silicon 14. That is, resistivity of the amorphous silicon 18 is high, so that a current flowing through the amorphous silicon 18 is very small. Therefore, the amorphous silicon 18 acts as an electric junction essentially as a diode directly below the current collecting electrode 19 and also acts as a passivation layer which lowers the surface recrystallization of a crystalline silicon 14 in the portion where there is no current collecting electrode.
