Abstract: PURPOSE:To photograph plural lightning discharges on one film by moving a lens in a breadthwise direction by length necessary for photography every time a lightning discharge is photographed. CONSTITUTION:When lightning strikes, its image is formed in a part A of the film 3 through the lens 7 and a slit 5 and the film 3 is loaded around a drum 1 and rotated in a constant direction, so that the state of the lightning begins to be photographed with time. A lightning detector 13 sends out its output in response to the flash of lightning to actuate a drive control circuit 14, which starts a motor for screw shaft rotary driving at the end of one-time photography after a time required to turn the drum 1 once. Then, the lens 7 engaged threadably with a screw shaft 8 is lowered to the position of a next photographic part B on the film 3 and then the motor 9 is stopped to wait for next lightning. This operation is repeated every time lightning strikes. When the final photography is completed, a detector 15 for the number of times of photography operates to turn off the power source 16 of the device, thereby closing a shutter 6. Thus, plural lightning discharges are photographed on one film and unmanned photography is carried out.

Filed: 1983-05-09
Abstract: PURPOSE:To prepare a photographing film with good quality by usually executing exposure control by a shutter time controlling system, and switching to an illuminating light quantity controlling system when a correct exposure time value of an object to be photographed is smaller than a prescribed value. CONSTITUTION:An electric conduction time to a shutter solenoid 21 is varied within a range in which the brightness of an object to be photographed, photodetected by a photodetecting part 6 is not brighter than the brightness set as a reference level to a comparator 12, and the photographing is executed by an exposure control ystem of a shutter time controlling system. On the other hand, when the brightness of the object to be photographed is brighter than brightness set to the comparator 12, namely, when a correct exposure time value of the object to be photographed is smaller than a prescribed value, a shutter driving pulse of a prescribed time is generated. Also, in this state, an illumination dimming circuit 19 executes dimming so that the brightness goes to darker than before. That is to say, the photographing is executed by the exposure control system of an illuminating light quantity controlling system. Accordingly, in such a way, the exposure quantity always made constant, and a photographing film with good quality can be prepared.

Title: Lighting equipment
Inventor: MINAGAWA RYOJI
IPC: H05B41/42
Filed: 1988-04-01
Abstract: PURPOSE:To obtain a high work-plane illuminance with an identical demand by providing a light increasing means for enlarging the light increasing rate of a round fluorescent lamp most contributing to an illuminance just under a light equipment more than that of other round fluorescent lamp. CONSTITUTION:When the movable contact 8d of a switch 8 is connected to contacts 8b1 and 8b2, operation of a relay 13 closes other contacts 14 and 15. A lamp 4 is lit with almost whole flux at a lower light increasing rate than that in the case that both lamps 4 and 5 are lit at the same rate. Light of the lamp 5 is increased, and an inductance 18 is adjusted in such a way as to provide the same work-plane illuminance of a lighting equipment as that in the case that both lamps 4 and 5 are lit at the same light increasing rate. Therefore, the light increasing rate of the lamp 5 much contributing to an illuminance just under the equipment is remarkably high while that of the lamp 4 nearly contributing thereto is low so that it will do that the total demand of the lamps 4 and 5 is smaller compared with that in the case that both lamps 4 and 5 are set at the same light increasing rate. This allows the same work- plane illuminance to be obtained with a smaller demand than that in the case that two lamps 4 and 5 are set at the same light increasing rate.
