PURPOSE:To prevent the surface temperature of a roller from greatly exceeding operation temperature by feeding electricity to a heat generation part continuously until the detected temperature reaches set temperature and feeding the electricity intermittently at a specific period after the detected temperature exceeds the set temperature. CONSTITUTION:A halogen lamp 22 is intermittent to rise in temperature and when the output voltage TEMP of a temperature sensor 23 exceeds a 2nd reference voltage V0, a comparison signal UP0 outputted by a comparing circuit 24a varies from 0 to 1. Then a signal CHP2 becomes 0 and a lamp driving signal HTDV also becomes 0, thereby interrupting the electric feeding to the halogen lamp 22. At this point of time, the temperature T2 of the halogen lamp exceeds the prescribed operation temperature T0, but the electricity is fed intermittently for a period from t1 to t2, so its peak is close to the temperature T0. Similarly, the surface temperature of the roller becomes T1 at time t3 and exceeds the operation temperature T0, but does not greatly exceeds the T0. Consequently, a fixing roller or components at its periphery are prevented from deteriorating owing to heat.

There is disclosed a harness for four legged farm animals, especially sheep, which comprises a fastening strap 19 which can be taken around the body of the animal, near to the neck and front legs of the animal, and at least one projecting member 22, 23 on the strap which applies a resisting and/or discomforting force to the animal whenever it attempts to roll on its back. <IMAGE>

JP The device includes a drum (14) rotatably mounted in a frame for storing pieces of different sizes to be sorted out. Elements (20,21) on the drum, including openings of different dimensions pass pieces of different sizes respectively. Members (22) are disposed peripherally around the drum in radial alignment with those openings of one dimension for collecting pieces of a partic. size passing through the openings. A drive device (16) rotates the drum about its own axis to discharge the pieces out of the drum. The device has a separator for separating superimposed sorted-out pieces from each other. A magnetic or optical reader reads information recorded on sorted-out pieces, e.g. tickets, and rejects those pieces with defective information.
