The present invention relates to a micro-hotplate device comprising a frame, a membrane, an active area comprising at least one active layer, and a heating structure designed to heat said active layer, said heating structure having concentric tracks and comprising inner tracks (20) and inner spaces (22) and outer tracks (24) and outer spaces (26) as being the one or two tracks and spaces located the furthest away from the center of the heating structure, characterized in that said outer tracks (24) are designed to be located closer to their neighboring tracks and / or are designed to have a width which is lower thanthose of the inner tracks (20), the width and the spacing of said inner tracks (20) being substantially constant.

The present invention relates to a distribution box (1) for a single-seed seed drill with a disc (4) provided with radial grooves (5) which are evenly spaced and open at the periphery of said disc (4), said disc (4) being mounted to rotate on a horizontal axis (4a) and separating a seed reservoir (6) from a suction device (7) so that the seeds are picked up from the reservoir (6) by said disc (4) using the stream of air at a depression and are held over at least part of their angular travel until they are expelled from a discharge opening (8). The box is notable in that each groove (5) has a suction hole (10) of a size smaller than that of the seeds that are to be distributed, said suction hole (10) opens onto a canal (11) of a width smaller than the diameter of the suction hole (10), said canal (11) is open as far as the periphery of the disc (4). The present invention also relates to a single-seed seed drill with at least one distribution box according to the invention.

The present invention relates to one adsorbing and rotating reversing device for the production of disposable toilet paper, and provides one transferring and reversing device with stable adsorbing transfer, constant transfer angle and convenient regulation of adsorption number. The transferring and reversing device features the chuck rotating mechanism comprising ring cam seat fixed on the main bearing seat and with spiral cam slot on the ring wall; the hollow chuck shaft with cam arm and cam connected in the lower end; and the hollow shaft below the chuck fixed inside the radial hole of the rotating disc. The device of the present invention can ensure the constant reversing interval, constant adsorbing disc angle, stable adsorption and precise transfer.

The invention discloses a device and a process for hot working of small-batch multi-specification camshafts, and belongs to the field of camshaft heat treatment. The device comprises a steel frame anda workbench, wherein two lifting devices are symmetrically arranged on the steel frames located on the two sides of the workbench, a rotary platform device is arranged on the workbench, the camshaftis movably connected in the rotary platform device, a cam is arranged on the camshaft, the lifting devices are correspondingly connected with telescopic rods, the tail end of one telescopic rod is connected with a peach tip induction coil, the tail end of the other telescopic rod is connected with a base circle induction coil, an isolation plate is arranged between the peach tip induction coil andthe base circle induction coil, and the workbench is provided with a PLC which is electrically connected with the lifting devices and the rotary platform device correspondingly. According to the device for hot working of the small-batch multi-specification camshafts and the process adopting the device, the quenching temperature and the depth of the hardened layer after quenching of the peach tippart of the cam are correspondingly same as the quenching temperature and the depth of the hardened layer after quenching of the base circle part of the cam, and the cams with different specificationscan be continuously heated.

A humidifying and air-cleaning disc and a disc assembly are provided to contain a large amount of water for a long time, thereby improving the humidification performance of the disc, by forming ribs on a surface of a disc body in a radial shape and protruding stoppers from the ribs in a tangential direction. A humidifying and air-cleaning disc(200) comprises a plate type disc body(210), ribs(220) formed on a surface of the disc body in a radial shape, and stoppers(223) respectively protruded from the ribs in a tangential direction. Each of the ribs includes a curve portion(221) curved oppositely to a rotation direction, and a bent portion(222) bent oppositely to a rotation direction between the curve portion and the stopper.
