Filed: 1982-06-07
Abstract: PURPOSE:To enable to set the effective holding water volume larger by a method wherein the opening of a feed water valve by means of a water level detector is made possible after the elapse of time necessary for draining the water in a heat collecting circuit from the stop of a heat collecting pump. CONSTITUTION:A control device C is energized through the normally closed contact point of a control relay X1 and provided with a timer T, which closes its own timer contact point after the elapse of the energizing time longer than the time necessary for draining the water in the heat collecting circuit, and an auxiliary relay X5 energized by said timer T. The feed water valve 7 is contrived to be open by energizing both said auxiliary relay X5 and a control relay X3. Furthermore, because the feeding of water is contrived to be not performed during the operation of the heat collecting pump 4 but performed in the case that the water level is below the starting level for feeding water L1 even when the water in the heat collecting circuit is drained after the end of the heat collecting operation, the holding water volume lying between the full water level H2 and the stopping level for feeding water H1 is not necessary to be larger than the volume drained from the heat collecting circuit and can be limited to the minimum required volume or in other words the effective holding water volume (the volume lying below H1) can be made larger and economical hot water holding is realized.

Then a CPU 2 selects successively inverters 5a and 6a to reduce the output impedances of both inverters and connects each end of resistances 5b and 6b to the earth. The input signal voltage decided by the voltage dividing ratio between both resistances is discriminated through the board 1 at this time point. Thus the names of both substrates 5 and 6 are recognized successively.

Then the material to be printed and an offset roll 23 come into external contact with each other to lift a movable table 35 so that the material to be printed may rotate. Further an anticorrosive ink 26 adhering to a pickup roll 24 is applied to a printing plate 22, and the ink adhering to the plate surface 27 is scraped off by a doctor blade 29. In the meantime, ink 26 in a recessed surface 28 is transferred to the external circumferential surface of the offset roll 23, then the external surface of the material to be printed 30 is to be printed. Since the external surface of the material to be printed is supported in non-contact manner by the static pressure gas bearing, anticorrosive ink after printing does not come off. The material to be printed 30 is supported by positioning the axial direction of the material through pushing from the other end of the material 30 using a pusher. Therefore, there will be no printing shift in axial direction.

Abstract: PURPOSE:To efficiently use the emitted light quantity of a stroboscope by setting shutter speed at a high speed side critical value based on the term of validity of light emission of the stroboscope when the stroboscope is applied to still picture photography. CONSTITUTION:A photocell equivalent to the photoelectric conversion part of a CCD discharges an electric charge before an electric charge discharge timing period based on the period. An actual exposure period is set after discharge, however, the stroboscope emits light by a stroboscope triggering timing, and the exposure period is completed by a timing when a transfer gate to transfer the electric charge from the photocell to a vertical shift register via the term of validity of the light emission of the stroboscope is opened. In such a way, a period when exposure by an element shutter is completed after a trigger is applied to the stroboscope and the transfer gate is opened can be secured so that the term of validity of the stroboscope can be included in the period as minimum requirement. In this way, processing can be performed so as to efficiently use the emitted light quantity of the stroboscope.

Filed: 1988-04-21
Abstract: PURPOSE:To conduct adequate flashing in a field emission gun by providing a memory means for storing pullout voltage becoming constant emission current and repeatedly flashing until the voltage reaches the specified value according to specification. CONSTITUTION:Pushing a starting button 10 causes a control circuit 8 to make a switch 5 for flashing on/off. The switch 5 causes a filament 3 to be heated to flash. Then, the circuit 8 controls a pullout voltage source 7 to increase gradually the voltage and stores in a memory 9 the voltage value which corresponds to the specified current value by measuring it with an emission ammeter 4. By repeating this, the increased voltage value in which an emitter surface is enough smooth is made known. Therefore, by conducting flashing in enough number of times or time with measuring the increase of the pullout voltage, an electron gun is always put in use in best condition to provide an image of better quality and less noise and the service life of the electron gun is extended.
