Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To eliminate such problems that the ventilating property of a residence becomes extremely unfavorable recently, and as a result of that imported materials, or a new construction materials, interior materials made of synthetic resins, and a large amount of paints are used, harmful volatile substances generated from these construction materials are filled in rooms, and also, a combustion gas or steam for heating or a kitchen are hard to discharge to the outside, and the propagation of harmful minute animals, or the phenomenon of sick house syndromes become notable, and ensuring a healthy living environment within the limits of present construction methods has become an urgent task. SOLUTION: In order to reduce the concentration of the harmful volatile substances which are considered to be the causes for the phenomenon of sick house syndromes, the circulation of air in the building must be improved, the purified outside air must be properly fed in, excessive moisture and volatile organic substances due to the highly air-tight and highly heat-insulating structure must be adsorbed and removed. The new construction materials, and cloths or coating materials comprising synthetic resins, which are considered to be the generating sources for the harmful volatile substances, are removed, and active charcoal is set at respective places in the building. Also, the circulation of air is improved, and at the same time, the active charcoal is housed in a container 1 which can increase the adsorbing effect.  Such remedies are suitable for the reduction of the concentration of the harmful volatile substances.

IPC: G11B20/10
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic image variable speed reproducing device capable of variable speed reproduction without image quality deterioration such as resolution lowering, aliasing and scanning line vertical blurring by obtaining interlaced scanning images of a proper parity as output images during variable speed reproduction. SOLUTION: In the case that dynamic images are reproduced from recorded dynamic image signals and the dynamic images (interlaced scanning images) are output at reproduction speed set at a speed different from the inherent reproduction speed of the dynamic images (namely, during variable speed reproduction), reproduced images are those obtained by progressive scanning. Since the scanning images include the field of both the parities of the interlaced scanning images, the scanning images are successively converted so as to be matched with the format of output interlaced scanning images, so that the interlaced scanning images of the proper parity can be obtained at any reproduction speed.
