Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent generation of pooling water due to an ice bank without particularly enlarging roof pitch and without particularlizing the structure of a roof, by providing a heating means for heating the upper surface of a roof to a positive snow melting temperature. SOLUTION: A plate-like heating body 2 as a heating means is fast stuck to the upper surface of an eaves end of a roof folded plate 1 along the shape of the folding slab. The plate-like heating body 2 is formed of a material mainly containing a flexible matrix resin and conductive carbon. The length of the planar heating body 2 in a direction of flow of the folded plate defined by a dimension form the eaves end to an outer wall, e.g. limited to the range from 200 to 300 mm. Thus, when snow has lain on the roof, heat from the planar heating body 2 is transmitted to the snow, to thereby heat the snow on the eaves end, icicles, and snow banks and melt the same. Accordingly, without particularly enlarging the pitch of the roof, or without making the roof in a particular structure, pooling water due to the ice bars can be easily and positively prevented from occurring.

Title: Nonaqueous system secondary battery
Inventor: AKAGI RYUICHI
IPC: H01M10/052
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To increase adhesion of a sintered body to a current collector and to enhance charging/discharging cycle characteristics by forming a first coating film containing pitch direct on the current collector, a second coating film containing more amount of pitch on the first coating film, and sintering these coating films under a non-oxidizing atmosphere to unite the coating films with the current collector. SOLUTION: In a negative electrode, a first coating film contains no or little pitch or carbon powder produced from the pitch, and adhesion of a sintered body to a current collector is increased. Since a second coating film has a larger content of pitch or the carbon powder produced from the pitch than the first coating film, it is easily graphitized by heat treatment, specific surface area of the carbonaceous material can be made small to retard irreversible reaction caused by side reaction such as decomposition of an electrolyte. The second coating film gives high conductivity to silicon which is an active material by heat treatment to develop high charge/discharge cycle characteristics.
