Filed: 1980-08-01
Abstract: PURPOSE: To achieve high-speed optical recording by using a special electron tube which uses a space optical modulating element capable of recording a picture normally and reversely with an electron beam, and reading the picture written in it  by a exclusively used light source.  
     CONSTITUTION: An electronic printer consists of the 1st optical system composed of an electric-beam scanning type electrooptical system 7, a light source 9 irradiating its face part 8 with light externally, a condenser lens 10, etc., and the 2nd optical system composed of an analyzing plate 12 and an image-forming lens 13 which send optical picture information read out from the face part 8 by the said light irradiation to a photoreceptor drum 14 for exposure. In this constitution, the amount of exposure to a photoreceptor is increased sufficiently only by increasing the intensity of the light source, and high-speed optical recording is therefore performed without using a high-sensitivity photoreceptor specially.

Moreover, the number of the control rod 3 and the coefficient of reactivity corresponding to the position of inserting the rod into the core are inputted into a controller 14 from a memory 13. On the basis of the inputs a drive speed of the control rod 3 is computed in the controller 14 to output a control rod drive command to a control rod driver 4. On the other hand, when the insertion position of the control rod 3 reaches the target position inputted from the setter 12, the outputting of the control rod drive command signal is stopped to the driver 4. Thus, the output of the core is controlled so as to keep changes in the output constant.

Filed: 1988-05-02
Abstract: PURPOSE:To make temperature distribution uniform and to increase mechanical strength by dividing corrugated plates into two or more between a gas inlet and a gas outlet, and positioning each corrugated plate by shifting one or half crest each other. CONSTITUTION:Fuel gas supplied from a passage hole 6 flows from a cut-out part 14 of a masking plate 13 into each of grooves 10C, 10D of the upper surface and the lower surface of a divided corrugated plate 10A. The gas supplied to the groove 10C on the upper surface reacts during flowing along the groove 10C and enters the groove 10D on the lower surface in the connecting part of a divided corrugated plate 10B on the outlet side. The gas supplied to the groove 10D on the lower surface of the divided corrugated plate 10A on the gas inlet side enters the groove 10C on the upper surface of the divided corrugated part 10B on the downstream side. Since the gas passed along the groove on the lower side of the corrugated plate 10A does not react, unreacted gas is supplied from the lower surface of the corrugated plate 10A to the upper surface of the corrugated plate 10B for using the unreacted gas.

Abstract: PROBLEM TO BE SOLVED: To obtain the position registration system for mobile communication by which the effect on the call connection service is minimized while extreme concentration of position registration operations is avoided even when all or many numbers of position registration information is lost. SOLUTION: An exchange station 11X receiving an incoming call retrieves a database 12 and when it is discriminated that position registration information of a mobile terminal equipment 13 to make call connection, the station 11X sends a location retrieval request signal 21 to exchange stations 111 -11N to allow them to retrieve the location of the terminal equipment 13. When the location is found out, the position registration information is recorded in the database 12. Since a caller subscriber 17 receives a guidance of redialing from a guidance device 18, the call connection is made based on the position registration information found out at the redialing point of time. Since the position registration information is updated at every reception of an incoming call in this way, extreme concentration of registration operations is avoided.
