Abstract: PURPOSE:To produce a photovoltaic device having uniform and stable characteristics by means of simple techniques, by utilizing a composite substrate having aluminium layers provided by plating an alloyed steel sheet with molten aluminium and having insulation layers provided by treating the surfaces of the aluminium layers by means of anodic oxidation. CONSTITUTION:The surface of a sheet of alloyed steel 1a having higher mechanical strength such as thermal resistance, elasticity or the like than aluminium are plated with molten aluminium, so that aluminium layers 1b and 1b' are provided thereon. The aluminium layers are then tempered and rolled so that undulation on the surface of the layers is decreased and that pin holes are filled up to smoothen the surfaces. The aluminium layers are finished in this manner so as to have a surface roughness Rmax of 0.2mum or less. Subsequently, the surfaces of the aluminium layers 1b and 1b' are treated by anodic oxidation for forming insulation layers 1c and 1c' of an oxide mainly composed of anodized aluminium Al2O3. Thus, a composite substrate 1 is obtained. Following processes are performed similarly with prior arts so as to obtain a photovoltaic device serving as a solar cell in which four amorphous silicon photovoltaic elements are connected in series.

Title: Nonaqueous electrolyte battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M6/16
Filed: 1985-10-16
Abstract: PURPOSE:To obtain a nonaqueous electrolyte battery excellent particularly in its low temperature characteristic and storage characteristic, by using an electrolytic liquid employing a mixed solvent including at least dioxolan and morpholine.

Therefore, a nonaqueous electrolyte battery which is excellent in its low temperature characteristic and storage characteristic is obtained. As morpholine, N- methylmorholine, N-etylmorpholine, etc. can be used. For example, an electrolytic liquidis obtained by resolving 1mol/1 of lithium perchlorate into a mixed solvent of dioxolan and morpholine with a volume ratio of 1:0.001, and a positive electrode is obtained by mixing MnO2 from which water is removed, carbon powder, and fluororesin powder with a weight ratio of 85:10:5. And forming the mixture by pressure, the electrode is treated at 250-350 deg.C. A negative electrode is made by a plate punched out from a rolled Li plate, and the flat nonaqueous electrolyte battery is made with nonwoven fabric of polypropylene as a separator. Degradation of this battery is extremely slow.

IPC: G06T9/00
Filed: 1989-09-05
Abstract: PURPOSE:To improve the coding efficiency by referencing a color component signal other than a color component being an object of coding in the case of classifying a prediction state. CONSTITUTION:When a G signal being a 2nd color component signal is coded and an R data of a same picture element already coded is referenced, the color of the coding object picture element is classified into the (W, R, Y, M) group (in the case of R=1) or into the (Bk, G, B, C) group (in the case of R=0), and the value of the G is easily predicted. Moreover, when a 3rd B signal is coded and binary data of R, G of the same picture element already coded are referenced, the color is classified into four groups, (W, Y) group (T=G=1), (R, M) group (R=1, G=0), (G, C) group (R=0, G=1), and (Bk, B) group (R=G=0), and the value E is further easily predicted. Since color information is used in addition to information from spatial correlation, the prediction coincidence ratio is improved and the coding efficiency is improved.

Abstract: PURPOSE:To eliminate waste of material while enabling the replacement for a short time in the alteration of material by branching a material supply vertical hole of a piston into a plurality of subholes near the center to heat in the vicinity of the branch point. CONSTITUTION:A vertical hole 14 of a piston 13 sliding within a cylinder 8 is branched into a plurality of subholes 15 and heated at the branch point 16 with an internal heater 17 buried in the piston 13. Therefore, a filamentous resin material 19 fed to the vertical hole 14 is heated and melted with a band heater 12 and an internal heater 17 at the branch point 16 and flows down shunted into the subholes 15. The melted resin passing through the subholes 15 flows down into a lower space 21 formed with the cylinder 8 and the piston 13 kept hot. Thus, as the resin is melted by internal heating of the cylinder, a higher heat efficiency is made possible to reduce the heat source of the equipment down to a small capacity while achieving a quick rising with a quick rise in the temperature.

Filed: 1988-09-14
Abstract: PURPOSE:To easily study and analyze the factors of the computer troubles by using a ROM containing an abnormality processing program in order to easily decide the occurrence of the computer troubles and also to eliminate the change of the program and the data at the occurrence of the troubles. CONSTITUTION:An abnormality processing program 8 is set into a ROM 3 and decides the abnormality via an abnormality check routine and protects other programs and data against the occurrence of the abnormality. At the same time, the contents of a main memory (RAM 4) and the register value of a CPU 2 are automatically saved into a floppy disk device 7 as necessary by the program 8 at the check of various types of abnormality of a computer and at an IPL operation. Therefore the data and programs that require the protection at the occurrence of troubles are automatically saved into the device 7 when various types of abnormality occur within the computer. Thus an operator does not need to decide the occurrence of troubles nor the protecting operations against these troubles. In addition, the destruction of the programs and data due to the malfunctions can be avoided and the study and the analysis are surely facilitated for the factors of troubles.
