Abstract: A wearable camera includes: a manipulator that receives operation by a user; a camera that picks up an image; a communicator that receives biological information on the user from a biosensor worn or owned by the user; and a controller that makes a transition from a vital reaction mode to a privacy mode in a case where the manipulator receives operation to specify the privacy mode, the vital reaction mode being a mode in which recording of the image picked-up by the camera is started when the biological information becomes abnormal, and the privacy mode being a mode in which image recording by the camera is not started even when the biological information becomes abnormal.

Abstract: In a brake signal converter device for a railway car a first signal conversion circuit is operative in response to a brake signal issued from the control stand of a first car in a form suitable for use by the first car and converts this brake signal to a form suitable for use by a second car and transmits it to the second car, while a first detector senses the brake commands issued at the first car and isolates the first car from these brake commands transmitted to the second car by means of a first switching section. In addition, brake signals issued from the second car are converted by a second signal conversion circuit to a form suitable for use by the first car and are transmitted to the first car, while a second detector senses the brake commands issued from the second car and isolates the second car from these brake commands transmitted to the first car by a second switching section.

As a modification of the above process, the slurry of the above second absorption step is further fed to the above first cooling step where unreacted limestone and SO.sub.x are reacted to form CaSO.sub.3.

Abstract: Sulfur oxides contained in the flue gas from coal-fired boiler are adsorbed by an adsorbent prepared by dry-distilling a portion of fuel coal satisfying at least one of requirements of an ash content lower than 15% by weight and a fixed carbon content of at least 50% by weight, thereby producing semi-coke, and activating the semi-coke by steam, and then the sulfur oxides-adsorbed adsorbent is heated to desorb the adsorbed sulfur oxides at a high concentration. The desorbed sulfur oxides are passed through a bed of semi-coke before the activation to recover the sulfur oxides as elemental sulfur.
