CONSTITUTION: A rotor 13 is arranged for a pin 12 through the upper opening part of the furnace 11. The rotor 13 is irradiated and heated by an infrared lamp 21. The pin 12 rotates the piled rotor 13 in the periphery of the infrared lamp 21 by a dynamo-electric motor 15 to infrared-irradiate and heat uniformly. A sensor 22 detects the infrared radiation of the wave length of 7 to 14μm radiated from the rotor 13. Based on the detection signal, the irradiating intensity of the infrared lamp 21 is controlled to keep the temp. of the rotor 13 constantly in a prescribed temp. As the wave length radiated from the infrared lamp 21 and that of the infrared rays radiated from the rotor is different from each other, the infrared rays from the heating rotor is measured to reach the prescribed temp. precisely in a short time.

Title: Communication system and station
Inventor: DANIERU YOHANESU HERARUDOUSU Y
IPC: H04L12/40
Filed: 1987-06-17
Abstract: A telecommunication system comprising a 2-wire bus conductor to which terminals have been connected via a transformer, in which communication takes place via voltage pulses Vp on the bus. Each voltage pulse Vp causes a magnetizing current im to be developed in the spurious self-inductance of each connected transformer. This current causes a faulty voltage to arise after termination of the pulse, entailing faulty information transfer. The invention offers a system in which a compensating current ic is generated in the connected transformers to combat this faulty voltage, so that at the instants of pulse termination the total magnetization of all transformers remains unchanged.

Abstract: PURPOSE:To permit to reduce the noise of a pump without accompanying the deterioration of efficiency and reduce further the size and weight of the pump by a simple constitution wherein a part or the whole of the size of clearance between the guide vane of the pump and an impeller is changed. CONSTITUTION:A pump is constituted so that the size G2 of clearance between the tongue 72 at the tip end of a guide vane 62 and the outer peripheral end of an impeller 3 is wider than the size G1 of the clearance between the tongue 71 at the tip end of the guide vane 61 and the outer peripheral end of the impeller 3. According to this constitution, turbulent flow is generated near the tongues 71, 72 at the tip ends of the guide vanes 61, 62 and noise is generated, however, side clearance size G2 is made considerably wide, therefore, generation of noise at these parts is restricted considerably. The leak current due to the clearance G2 is restricted by the small clearance G1 and, therefore, the loss of leakage is not increased substantially as a whole. According to this constitution, the deterioration of efficiency due to the increase of loss will never be caused, generation of noise due to high-speed operation may be restricted effectively and the improvement of efficiency as well as the reduction of the size and weight of the pump may be contrived.
