摘要： A CO2 fixation system for fixing Co2 gas existing in the atmosphere or in an exhaust gas emitted from factories and other burning sites. The system includes a fermenting tank for anaerobically fermenting organic wastes, whereby methane gas is produced. The methane gas is decomposed and hydrogen gas is produced. The hydrogen gas is reacted with the CO2 gas to produce carbon powder and water, whereby the CO2 gas is fixed to become harmless to the global warming.

摘要： The mechanism is for use with a tape recorder of the cassette type in which the direction of rotation of tape reels within a cassette is automatically reversed at the end of taking up the tape. A drive gear is movably supported between a pair of driven gears engageable with the respective reels, so as to be able to engage with either one of the driven gears, and the drive gear is spring biased toward a line connecting the rotating axes of the driven gears. The rotation of the drive gear in one direction causes its engagement with the corresponding driven gear and, at the end of taking up the tape, a substantial displacement of the drive gear against, the spring bias occurs through an increase in load, thereby changing over the direction of rotation of a motor for driving the drive gear. A mechanism is provided for resetting or maintaining the drive mechanism in a given condition which enables the reels to start to rotate in a given direction whenever a tape cassette is removed from the recorder.

摘要： An anaerobic fermentation part generates gas containing methane and carbon dioxide by anaerobically fermenting biomass. The gas is passed to a methane.carbon dioxide separation part to be separated into methane and carbon dioxide, and part of the separated methane is fed to a methane reforming part to be decomposed into carbon and hydrogen under the presence of a catalyst. The carbon dioxide separated in the methane.carbon dioxide separation part and the hydrogen formed in the methane reforming part are fed to a carbon dioxide fixing part, which in turn reacts the carbon dioxide with the hydrogen under the presence of a catalyst for continuously forming carbon and hydrogen and fixing the carbon dioxide.

摘要： A device for the accurate placement of a record sheet having a plurality of positioning holes, and recording area on a recorder-player having a recording-playing head and placement pins engageable with the placement holes of the record sheet, comprises a bottom placement plate having an indented area substantially corresponding to the shape of the record sheet, an opening in the indented area corresponding to the shape of the recording surface of the record sheet, and a plurality of apertures corresponding to the placement holes of the record sheet and a covering retainer plate having a plurality of apertures corresponding to the holes of the record sheet and the apertures of the placement plate. The placement plate and retainer plate form a pocket into which a record sheet is insertable for coarse alignment with the placement pins of the recorder-player. The pocket assembly is displaceable toward the recorder-player to bring the record sheet into engagement with the placement pins which are beveled to further align the recording surface with the recording-playing head of the recorder-player.

摘要： The mechanism is primarily for use in the tape drive of a tape recorder for automatically reversing direction of rotation of a pair of rotating members and/or stopping such members through mechanical detection of a sudden variation of load which may occur at the end of taking-up of a tape. A drive roller is supported on a swingable arm for swinging motion to be brought into peripheral engagement with a selected one of the pair of rotating members. Mechanism is provided for causing the swinging motion of the drive roller upon the reversal of rotation of the latter to change its engagement with the rotating members from one to the other. An engaging member is supported concentrically with, and for relative rotation by a predetermined angle to, each rotating member and a coil spring is connected therebetween. The relative rotation of an amount beyond a predetermined value, which is caused by an increase of load, causes the reversal of direction of rotation of the drive roller through actuating mechanism for an electrical switch which controls a drive motor for the drive roller.
