Abstract: PURPOSE:To obtain a high speed and high reliability by using an electrooptic deflecting element and a photodetector which obtains a digital signal according to a photodetection position. CONSTITUTION:Luminous flux from a light source 1 such as a laser diode is shaped by a cylindrical lens 2 into a beltlike beam, which is deflected by an electrooptic deflecting element 3, driven by an analog signal to be converted into a digital signal, at a deflection angle which corresponds to the analog signal, so that the deflected beam is caused to illuminate a photodetector 9 through a prism 4 for deflection angle amplification. The photodetector 9 consists of lateral columns of photoelectric converting elements 16-19 which correspond to a binary code of a desired number of bits, and its photodetection surface is covered with an Al film 21 constituting a binary code pattern 20 by an opening part and a light shielding part, so the digital signal is obtained by the incidence of the beltlike beam[e.g. dotted line (a)].

Filed: 1985-03-25
Abstract: PURPOSE:To shorten a preheating time to a large extent and to reduce the thermal shock to a transducer, by transmitting the heat of a high temp. liquid to the transducer through a heating medium and a highly heat-conductive liquid. CONSTITUTION:Prior to the separation operation of a control rod, a holding tube 13 is pierced through a shield plug 14 to be fallen into a nuclear reactor storing vessel and temporarily stopped in such a state that a heat-conductive body 35 is immersed in a cooling material but the bottom surface 13a of the lower end part of the holding tube 13 is not immersed. Because the cooling material 3 is held to high temp., the hermetically sealed container 37 of the heating medium 35 is quickly heated and the heat of said medium 35 is gradually conducted to a heat conductive rod 36 through a metal small sphere 38 being a heat resistant element and reaches a transducer 8 relatively rapidly through the bottom part 13a and heating liquid medium 34 to preheat the same to the vicinity of the temp. of the cooling material 3. Therefore, thermal shock is not generated in the transducer 8 at all and a preheating time is shortened to a large extent. When the transducer 8 almost reaches the temp. of the cooling material 3, the holding tube 13 is further fallen to monitor the confirmation of the separation of the control rod.
