Title: Image pickup device
Inventor: SUGIMOTO TSUTOMU
IPC: H04N5/335
Filed: 1981-10-30
Abstract: PURPOSE:To obtain an image pickup device which allows automatic exposure regulation through only an electric circuit without any movable part, by varying and adjusting the frequency of a scanning clock pulse according to the brightness of an image pickup objective. CONSTITUTION:An illumination photometer 13 is fitted on a camera head 11 to measure the brightness of a subject. An image sensor 12, on the other hand, is driven by a pulse from the driving circuit 14a in a control circuit 14, and its output is applied to an arithmetic part 15 for picture data processing through an amplifying circuit 14b. At this time, the driving pulse generated by said driving circuit 14a depends upon a clock oscillator 17 equipped with a voltage frequency converter which varies in frequency with the brightness of the illumination photometer 13, so a pulse for driving each element of the image sensor has a frequency depending upon the brightness, and a scanning time (exposure time of element) also varies, thereby performing automatic exposure regulation.

Title: Temperature controller for fuel battery
Inventor: FUJII MASAO
IPC: H01M8/04
Filed: 1981-10-30
Abstract: PURPOSE:To obviate the necessity of the motive power of accessories by allowing the sealed medium in a heat exchanging pipe to circulate naturally, with regard to a temperature controller for fuel battery through which heating is performed for accelerating reaction on starting and the heat generated during steady operation is removed. CONSTITUTION:In order to cool a fuel battery in operation, the heat generated in each layer of a layer-built fuel battery is transmitted to temperature controlling plates 1 and 3 from both the upper and lower sides according to the temperature gradient and further transmitted to a heat exchanging pipe 5, in which the sealed medium is vaporized, and the heat of evaporation is removed, and thus cooling is performed. The generated vapour rises-up and reaches a high-position pipe 7, being cooled by a heat exchanger 12 which 13 operating for heat-radiation, condensed to liquid and desceuds to a low-position pipe 9 by the self-weight, and returns to the heat exchanging pipe 5. Although a fuel battery is heated to carry-out chemical reaction smoothly on starting, the medium in the low-position pipe 8 is heated to form vapour, which rises-up and is further heated in the high-position pipe 7, and flows into the heat exchanging pipe 5 to give heat to the temperature controlling plates 1 and 3.
