Title: Encoding radiowave repeater
Inventor: TODA KOJI
IPC: H03H7/42
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To repeat radiowave by selecting only a specified radiowave among the radiowave from outside and transmitting it as the radiowave again. SOLUTION: The radiowave received by an antenna A is received as an inputted electric signal by a blind shaped electrode T, converted into a surface acoustic wave and propagated near a surface of a plate surface with which each electrode of a piezoelectric substrate is provided. Only when an electrode pattern of an electrode U is coincident with a signal pattern of an electric signal E among the inputted electric signals, a pulse signal is outputted by the electrode U. A switch 4 is connected by the pulse signal. The surface acoustic wave which reaches a blind shaped electrode S is outputted by being converted into the electric signal by the blind shaped electrode S, and transmitted as a radio signal from an antenna B by way of the switch 4 in a connected state.

Abstract: PURPOSE: To enable optimum exposure to be obtained under any conditions by isolating the clamp of a meter pointer from a release plate, clamping the same in the initial state of performing extension of the lens actually after distance measurement and determining exposure information at the brightness immediate before release.  
     CONSTITUTION: Shutter charging is performed by turning a winding-up lever 1 and the range to be taken is determined with a finder eyepiece lens 36. At the same time a distance measuring index 38b is matched to the subject. When a main switch S 1  is turned ON by actuating a shutter button, an automatic distance detector 33 actuates and upon completing of distance measurement, a magnet 23 actuates to turn a shutter release arm 20 counterclockwise, by which a slide plate 17 is made pushable. The subsequent pushing-in causes a focus actuating ring 7 to be begun to be turned counterclockwise by a spring 8, by which a clamp plate 13 is turned. This causes a meter 27 to be actuated by the photo detector in correspondence to the luminance of the subject. The clamp pointer 28 having been swung thereby is held between the stationary clamp plate 29 and the rotating angle of the saw tooth 12 corresponding to the brightness of the subject is set by the saw tooth having followed up, whereby the aperture is determined.
