Title: Natural illumination type bright frame finder
Inventor: MORI NOBUYOSHI
IPC: G02B13/16
Filed: 1991-05-15
Abstract: PURPOSE:To provide the finder which has small diopter difference between the periphery part and center part of its visual field and enables an optical image frame to excellently be seen by using an aspherical surface which increases in radius of curvature from the optical axis of a positive lens to the periphery as one surface of the positive lens. CONSTITUTION:A prism 5 is interposed between an objective 4 and an ocular 7 and provided with a half-mirror 6 to enable the optical image frame 1 and visual field to be seen together on the same plane. An optical image frame system which displays the light image frame 1 consists of the light image frame 1, a reflecting mirror 2 which bends a light beam by 90 deg., a target lens 3 which refracts the light beam, the prism 5, the half-mirror 6, and the ocular 7. Then the aspherical surface which increases in radius of curvature from the center part of the lens to the peripheral part is used as one surface of the ocular 7 or one surface of the target lens 3 and then the refractive index of the lens to a light beam passing through the peripheral part of the lens is decreased to prevent an image of the optical image frame 1 from being too far, thereby obtaining the finder which enables the optical image frame 1 to excellently be seen.

Abstract: PURPOSE: To make it possible to elevate the efficiency by a simple constitution, by comparing the voltage by a collector current of the transistor with the DC output voltage, and forcibly executing turn-off, in the switching electric power source of the ringing choke system.  
     CONSTITUTION: When the transistor 3 is turned on by a base current supplied to the base of the transistor 3 through the resistance 14, the collector current increases gradually, and the voltage E 1  is generated in the resistance 11. On the other hand,  the divided voltage E 3  which has been divided by the resistance 17, 18 as to the  voltage stored in the smoothing condenser 16 in proportion to the voltage E 2  of the  output winding IC is compared with the voltage E 1  between terminals of the resistance 11 by the transistor 19 to which the positive feedback has been performed by  the capacitor C 22 . When its difference has exceeded the prescribed value, the transistor 19 is turned on, and subsequently the transistor 21 is also turned on. Accordingly, the collector voltage of the transistor 21 drops, and the transistor 19 drops, as  well. Since the positive feedback is applied between the transistors 19, 21 by the  capacitor 22, extremely high gain is obtained, and the switching operation can be  executed at a high speed.
