Filed: 1983-03-23
Abstract: PURPOSE:To simplify a mechanical constitution and to facilitate remote operation by providing a time limiting circuit which supplies an input for opening a diaphragm to an electromagnetic driving mechanism for a desired time. CONSTITUTION:A potentiometer 9 is set to a desired value and the time limit of the time limiting circuit 5 is set to a desired exposure time; when a switch 8 is pressed, the output of an element 9 is applied to the positive input of a subtracting circuit 6, amplified by an amplifier 7, and inputted to the electromagnetic driving mechanism 2, and at the same time, an output corresponding to the angle of rotation of a magnet is sent out of a magnetic sensitive element 3 by the rotation of the magnet and applied to the negative input of an element 6. When the output of an element 4 is made nearly equal to the output of the potentiometer 9, the mechanism 2 enters a balanced state, so a diaphragm 1 is driven by the mechanism 2 to open up to the degree of opening corresponding to the output of the potentiometer 9. This state is continued for the shutter time set in the time limiting circuit 5, and the positive input to the subtracting circuit 6 is cut off the set time later to hold the input to the amplifier 7 negative; and the mechanism 2 receovers by its output to close the diaphragm 1.

Title: Screen size discrimination device
Inventor: EGUCHI YOICHI
IPC: H04N5/46
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To correctly discriminate the screen size of a video signal by checking continuity of aspect data for a specific field period. SOLUTION: A luminance level comparator circuit 11a compares a luminance signal level of an input video signal with a specific video image discrimination level to provide the output of a high or a low level discrimination signal to a video discrimination circuit 11c. The video discrimination circuit 11c identifies a line where a luminance signal is in existence from a line where no luminance signal is in existence based on a discrimination signal received from the luminance level comparator circuit 11a and a line position identification signal received from a timing generating circuit 11b. Based on the identification result, an image start line position and an image end line position are detected and a wide discrimination control circuit 12 reads aspect data detected for each field for a specific period.  The screen size of the video signal is correctly discriminated by checking the continuity of the read aspect data.

Input data to terminal device 10 is normally at the high level and, for example, if data d2 changes, OR circuit 13 generates a high- level output to turn on transistor Tr2, outputting an interruption signal. This signal flows from power source E by way of diode D1, transmission line L1 and photocoupler PC2 at the center side to turn on the phototransistor of photocoupler PC2 at the center side, thereby informing center 20 of the occurrence of the interruption of terminal device 10. Then, the center selects terminal device 10 and discriminates the change of input data d2.

Inventor: ABE YUTAKA
IPC: A63F7/02
Filed: 1988-02-29
Abstract: PURPOSE:To prevent the occurrence of erroneous detection and omission of detection due to external light, by a method wherein a body is formed by a material which visible beams and infrared rays do not transmit, and a filter which light emitted from an emission element can permeate is disposed in front of an emission element and a receiving element. CONSTITUTION:A body 10 is formed in a manner to cover a lower case 11 with an upper case 12. The body 10 is formed by a material which visible beams and infrared rays can transmit, and a filter 25 which light emitted from an emission element 22 can transmit is disposed in front of the emission element 22 and a receiving element 23. Since visible beams and infrared rays do not transmit the body 10, external light hardly comes in the receiving element 23, and only light from the emission element 22 capable of transmitting the filter 25 comes in the receiving element 23. Namely, since external light does not come in the receiving element 23, erroneous detection and omission of detection due to external light is prevented from occurring.
