摘要： An apparatus for detecting concentrations of a plurality of gas components has a single polarographic sensor capable of detecting an oxygen concentration and a composite concentration of oxygen gas, carbon dioxide gas and steam. A first voltage is applied to the polarographic sensor which then measures only the oxygen concentration, or a second voltage is applied to the sensor which then measures only the composite concentration of oxygen gas, carbon dioxide gas and steam. The first and second voltages are applied to the sensor in a time division manner. Upon application of first and second voltages in such a time division manner, corresponding currents flowing through the sensor are detected to obtain signals corresponding to the oxygen concentration and the composite concentration of oxygen gas, carbon dioxide gas and steam. The signal corresponding to the oxygen concentration is subtracted by an operational amplifier from the signal corresponding to the composite concentration of oxygen gas, carbon dioxide gas and steam, thereby obtaining a signal representing a composite concentration of carbon dioxide gas and steam.

The first and second element regions are adjacent in a direction orthogonal to a direction in which current flows, and are formed in a loop shape over the entire element region when the semiconductor layer is viewed from above. The first main electrode is electrically connected to the third main electrode, and the second main electrode is electrically connected to the fourth main electrode. When the semiconductor layer is viewed from above, a ratio of a length of the first main electrode to a length of the second main electrode is larger than a ratio of a length of the third main electrode to a length of the fourth main electrode.

摘要： A photocopying system without using an intermediate film is disclosed. In this system, the photo-pressure sensitive sheet and an original are tightly overlapped on a photocopying stage. Scratching scars generated by friction therebetween can be avoided by drive means for changing a distance therebetween. Images on the reverse side of the original can be protected from being duplicated by changing a direction of a light beam. Figure/character images, as well as image trimming, can be arbitrarily photocopied by exposing to a light through display on liquid crystal panel.

摘要： An image recording apparatus including a pattern forming device for forming a light-shielding pattern on one of opposite surfaces of a photosensitive recording medium. The light-shielding pattern is formed of a light-shielding material which is capable of shielding a radiation. The apparatus further includes an exposing device for irradiating the above-indicated one surface of the recording medium, and thereby forming an optical latent image which corresponds to the light-shielding pattern. The light-shielding pattern is removed by a cleaner from the recording medium after the optical latent image is formed. The optical latent image formed on the medium is developed into a visible image.

A pressure-sensitive recording sheet can be fed to pass between the pressure developing rollers, and has a pressure-sensitive image bearing layer on one surface thereof. A developer sheet can selectively be fed to pass between the pressure developing rollers in superposed relation to the pressure-sensitive image bearing layer. The pressure developing rollers are spaced from each other by a gap which is greater than the thickness of the pressure-sensitive sheet and smaller than the combined thickness of the pressure-sensitive sheet and the developer sheet. The pressure developing device also includes a friction roller held against a surface of the pressure-sensitive recording sheet opposite to the image bearing layer and rotatable for frictionally feeding the pressure-sensitive recording sheet.
