    摘要: This invention relates to light measuring devices, and, more particularly, to light measure devices for a circuit receiving reflected light from an object being photographed with flash illumination. The invention is to obtain an alternating current component (the flash illumination) alone or a mixture of the alternating current component and a fraction of a direct current component (ambient light) as the output of the light measuring circuit only by arranging a feedback circuit having a prescribed gain for low frequencies in the feedback network of the light measuring circuit, the fraction being adjustable by varying the prescribed gain.

    摘要: A linear scale features a removable scale channel and adjustable head assembly for easy, accurate, permanent positioning on a machine tool bed or other mobile device. The scale channel, and a matching positioning tool, has balls at opposite ends engaging a socketed mounting bracket. When in use, the flexible socket coupling is clamped into immobility by removable covers over open faces of the mounting brackets. During installation, the mounting brackets engage the positioning tool rather than the scale channel and with the flexible-socket couplings free to gimbal. The mounting brackets are fixed to the machine tool at a fixed axial spacing determined by the length of the positioning tool but at whatever angular attitude best suits the supporting surface of the machine tool. The positioning tool is then removed and replaced by the scale channel. The head assembly is fixed to a stationary stand opposite the scale channel. An adjustable mechanism allows the sliding head of the head assembly to move perpendicular to the axial direction relative to a base fixed to the stand.

    摘要: A flash device for a photographic camera is arranged either to inhibit a flashing action or to shift the control mode of the camera from flash photography to daylight photography in cases where an object to be photographed is located outside of the adequately operatable range of distance. A pre-flashing action is performed to detect a distance to the object when a main capacitor is charged to a given level before the capacitor is amply charged for flash photography. Then flash photographing is performed at an aperture value determined on the basis of the detected distance when the distance is within the adequately operatable distance range. In the case where the detected distance is outside of the adequately operatable distance range, the main capacitor is further charged for an increased flashing power. After that, a distance to the object is again detected by a second pre-flashing action before the flash photographing is carried out at an aperture value determined on the basis of the distance detected by the second pre-flashing action. The flash photographing arrangement thus permits seizing a shutter chance in flash photographing an object located at relatively short distance without waiting until the main capacitor is amply charged.

    摘要: A display device in the finder of a camera has a plurality of digits of light-emitting elements for displaying exposure information on the side of a frame of field of view of the finder. The light-emitting element of the nearest one of the digits to the frame of field of view is made brightest, and, as the distance from the frame increases, the brightness of the light-emitting element of each digit is made lower. Therefore, the apparent brightnesses of all the light-emitting elements become almost equal to one another, permitting the observer to read the displayed information with ease and clearness.
