Title: Light modulator
Inventor: SHIODA AKIRA
IPC: G06G7/60
Filed: 1990-10-01
Abstract: PURPOSE:To change a light transmissivity by an electronic control by constituting a light modulation mask of a magnetic layer constituted of (n) layers equipped with plural unit cells which are magnetically insulated and isolated by transparent dielectric layers, and controlling the direction of the magnetization of the unit cell. CONSTITUTION:A light 14 from an LED passes a first polarizing plate 10. When the polarizing face is a straight line polarization in an upward and downward direction, the counterclockwise rotation of the angle of rotation of the polarizing face is defined as plus. When the light 14 passes each unit cell 15, 16, and 17 of magnetic layers A, B, and C, the light is rotated at +2 or -2 degree in the cell 15, at +4 or -4 degree in the cell 16, and at +8 or -8 degree in the cell 17, by the direction of the magnetization, so that the light passing the layers A-C can realize the angle of rotation in eight stages (2<3>) from -14 to +14 degree. Then, the angle of a second polarizing plate 12 is set at the angle at which the straight line polarization of the polarizing face at -14 degree is completely shielded, so that the quantity of the transmitting lights is increased according as the angle of rotation is increased at -10 degree, and -6 degree, and the transmissivity in the eight stages (2<3>) can be realized. Thus, the light transmissivity in the 2<n> stages can be controlled by operating the electronic control of the direction of the magnetization of the magnetic layer constituted of the (n) layers.

Abstract: PURPOSE:To keep the initial accuracy at the time of manufacture of the camera substantially by providing a means for counting the total operating number of times in the camera depending on the tendency that the accuracy is decreased due to repetitive uses and using the output to apply correction of drive control. CONSTITUTION:When the number of times of operation of a camera is increased and an output from a total frame number counter 49 is, e.g., 10000 times or over, a lens excess feed correction signal is sent to an arithmetic circuit 46a. By estimating the increase in the play of feeding due to wear of feed screws 23, 29, the arithmetic circuit 46a sends an output corrected to feed the lens slightly higher to lens control circuits 51, 52. Then feed screws 23, 29 are rotated excessively to drive the lenses 21, 27 to obtain a prescribed proper lens position. Thus, since the control of the aperture drive mechanism and the lens drive mechanism or the like is corrected in response to the number of times of use of the camera after manufacture, the deterioration in the accuracy of the mechanism is prevented substantially.

Abstract: PURPOSE:To make uniform and stable discharge possible by forming a conductive film in part of the dielectric material forming a discharge electrode, the conductive film defining a discharge region in the surface on the metallic electrode side of the dielectric material. CONSTITUTION:A conductive film 17 is provided on one surface of a dielectric material 13 for contact with a metallic electrode 14. The conductive film 17 is a metal coating such as silver, which is formed by evaporation, spraying or printing, and it does not cover the whole surface of the dielectric material 13, but it is formed in part of the surface so as not to extend over the end portion of the dielectric material 13. In addition, the surface of the metallic electrode 14 put in close contact with the conductive film 17 is formed rather smaller than the area of the conductive film 17. Since the dielectric material is thin, it accurately reflects the shape of the conductive film 17 and produces discharge between the dielectric material 13 of the opposite discharge electrode 4. Since the conductive film 17 and the metallic electrode 14 are constructed so that they are closely contacted with each other for instance, by a conductive adhesive, the power supply is performed by applying an alternating voltage to the metallic electrode 14 to cause an alternating voltage across the conductive film 17, so that discharge occurs between the dielectric materials 13.
