    • PROBLEM TO BE SOLVED: To quickly thaw or sublimate snow, and easily eliminate snow by surrounding solid-phase water with an airtight enclosure and decompressing within the enclosure. SOLUTION: An open part of a rubber bag 15 is attached to the lower end of an annular frame 12, and an open/close cover 11 is fitted to the upper part of the annular frame 12, thereby forming a sealed vessel. The side wall of the annular frame 12 is fitted with a conduit tube 17 having one end open to the inside of the frame 12 and the other end connected to a vacuum pump 16. Snow or ice is supplied to the rubber bag 15 and the open/close cover is closed, thereby being sealed between the cover and the annular fame 12. Then, the vacuum pump 16 is operated to evacuate and keep the sealed vessel in a vacuum condition. As a result, when the sealed vessel is internally decompressed, the atmosphere pushes and compresses the flexible rubber bag 15, and crushes the snow inside. In this case, a solid-phase easily changes to a gaseous-phase or liquid-phase, due to decompression, and vapors are discharged through the vacuum pump 16. Also, water stagnating in the rubber bag 12 is discharged by opening a valve 18 after stopping the operation of the vacuum pump 16 and making the internal pressure of the rubber bag 15 equal to the atmospheric pressure. According to this construction, solid-phase water can be efficiently eliminated.

    • PROBLEM TO BE SOLVED: To easily set a television channel to the channel of a game machine by controlling an outlet for the game machine and a video input terminal by a switch. SOLUTION: The video/audio output cord 7 of the game machine is connected to the video/audio input terminal 2 of this television 4 and then, a cord 6 for the power source of the game machine is connected to the outlet 1 for the game machine of the television 4. Then, when the switch 3 attached to the television 4 is pressed, the power of the television 4 is supplied, a current is made to flow to the outlet 1 for the game machine and the power of the game machine for a household is turned on. Then, video signals and audio signals inputted from the video/ audio input terminal 2 are outputted respectively from the screen and the speaker of the television 4. When the power source cord 6 and the video/audio cord 7 of the game machine 5 for the household are connected to the television 4, since the game machine 5 for the household can be used just by pressing the switch 3 of the television 4, the handling time of switching the channel is reduced. Also, the switch can turn off the power and interrupt the input of signals.

    • PURPOSE:To eliminate bad smell of a ginseng and obtain a readily drinkable ginseng vinegar, by adding a powdered ginseng and perfume to an alcoholic solution containing an added natural fruit juice containing citric acid and dissolving and incorporating drug effect components thereof in the solution. CONSTITUTION:A natural concentrated fruit juice, e.g. lemon, containing citric acid is added to an alcoholic drink, e.g. SHOCHU (low-class distilled spirit), to prepare a weakly acidic alcoholic solution with 25 deg. alcohol content at about 3 pH. About 500g powdery ginseng is then mixed in 10l alcoholic solution and about 200g fennel, about 100g clove and about 100g Japanese cinnamon as perfumes are mixed. The resultant alcoholic solution containing the above- mentioned materials is allowed to stand for about 1 month to age the ginseng and perfumes, etc., and drug effect components are dissolved and contained in the alcoholic solution. The ginseng vinegar thus obtained holds drug effect components, e.g. stomachic agent, etc.
