摘要： A laser beam detecting device is disclosed for detecting a laser beam which is emitted from a laser beam generator and which forms a reference plane. A power supply for a laser beam sensor used in the laser beam detecting device is turned OFF automatically when a construction machine with the laser beam detecting device attached thereto is not in operation, while upon operation of the construction machine, the resulting vibration is detected by means of a vibration sensor and the power supply for the beam sensor is turned ON. By so doing, there is attained a superior power saving characteristic and it is possible to effect operation over a long time even with use of cells or a battery.

摘要： This invention relates to a gas refining system wherein a high-temperature and high-pressure reducing gas is introduced into a fixed-bed desulfurizer packed with an adsorbent by which sulfur compounds contained in the high-temperature and high-pressure reducing gas are adsorbed and removed in the form of a sulfide, and the adsorbent having the sulfide adsorbed thereon is regenerated by roasting it with a regenerating gas containing oxygen, characterized in that the gas refining system is equipped with oxygen concentration control means for controlling the oxygen concentration in the regenerating gas introduced into the desulfurizer so as to keep the internal temperature of the desulfurizer during the regeneration reaction within the allowable temperature range of the adsorbent. This invention includes an embodiment in which the exhaust gas obtained after the regeneration reaction gas is brought into contact with a calcium compound-containing slurry to recover gypsum is recycled to the desulfurizer for use as the regenerating gas for the adsorbent. Thus, the adverse effect of the heat of regeneration reaction on the adsorbent used in the fixed-bed desulfurizer can be avoided positively and easily.

摘要： An encoder for measuring devices having a code plate including binary grating patterns arranged in a given regular fashion and forming a first scale, a linear sensor including photodiode elements arranged with fixed intervals and forming a second scale disposed in parallel with the code plate, and processor means for absolute-interpolating one pitch of the first or second scale on the basis of reading data or information obtained from the linear sensor corresponding to a relative position of the patterns to the elements.When the number of the scale divisions of the first scale within a fixed range is N, the number of the scale divisions of the second scale is N+1. Accordingly, when the first scale is a main scale, the second scale is a vernier scale. The processor means detects a phase inverting point corresponding to the interpolation point on the basis of the reading data. The processor means performs the absolute interpolation by detecting the phase inverting point.

摘要： A gas refining method for adsorbing a reducing gas obtained by pressure gasification of coal or oil comprises introducing a reducing gas stream into an adsorbing and removing zone where it contacts an adsorbent. Sulfur-containing compounds are adsorbed onto the adsorbent and a first oxygen-containing gas stream is introduced into the adsorbing and removing zone in order to form a regeneration gas containing sulfur dioxide. The regeneration gas is contacted with a second oxygen-containing stream and a calcium-containing liquid slurry to effect absorption of sulfur dioxide by the slurry and precipitation of a gypsum compound. The temperature of the slurry is varied to cause selective precipitation of 60 -gypsum hemihydrate or gypsum dihydrate.
