Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a light reception device which does not erroneously receive the light signal of an adjacent wavelength which is wavelength-multiplexed even if the light signal of the wavelength to be received is cut. SOLUTION: Light whose center wavelength is equal to the wavelength of one arbitrary light signal and which is extracted by an optical filter is received by an opto/electric conversion circuit 12 among wavelength-multiplexed light of the plural approximate light signals whose wavelengths are overlapped with the tone signals different in the frequencies. A tone signal extraction circuit 15 extracts the frequency component of the tone signal overlapped with the light signal of the wavelength equal to the center wavelength of the optical filter. When the extracted signal level is less than a reference value, a comparison circuit 19 outputs a reset signal to an identification circuit 16.  When the light signal of the desired wavelength is cut, the output of the tone signal extraction circuit 15 drops and the identification circuit 16 is reset, the light signal of the adjacent wavelength is prevented from being erroneously identified and reproduced even if the clock signal is extracted from the light signal of the adjacent wavelength.

IPC: B65D85/86
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To apply predetermined cushioning function to a packing bag itself without separately preparing a cushion material. SOLUTION: A bag comprises a double structure including an inner bag 4 for sealing an object 2 to be packed and an outer bag 5 for sealing the inner bag 4 via a certain space, wherein the inner bag 4 and the outer bag 5 are integrated at one or more portions. Thus constituted, since a certain space can be held in the outer bag 5, this space provides a cushioning effect, so that a double-structured sealing-type packing bag including cushioning function in the bag itself can be obtained. Gas at a higher pressure than an atmospheric pressure is sealed into the space between the inner bag 4 and the outer bag 5 of the double structure, thereby providing the double-structured sealing-type packing bag with the outer bag 5 constantly swollen like a balloon.  In addition, if the inner bag 4 and the outer bag 5 are integrated at a bottom, the inner bag 4 is held in the vicinity of a center of the outer bag 5, so that a uniform space is held in the entire packing bag thereby preventing the cushioning function from being lost.
