Filed: 1982-01-05
Abstract: PURPOSE:To protect circuit components of a repeater, by providing a switching means which is opened at the application of opposite polarity, between a power feeding line and a repeater amplifier. CONSTITUTION:A normally-closed relay contact 8 is inserted between a repeater amplifier 1 and a Zener diode 7 for surge protection, and a parallel connection circuit consisting of a relay coil 9 and a diode 10 forward-biased to a conventional feeding polarity is inserted in a feeding path 6'. At the normal feeding, a feeding current flows through an inner conductors 2a, a power separation filter 4, the contact 8, the amplifier 1, the diode 10, the line 6', a power separation filter 4', and an inner conductor 2a'. On the other hand, at feeding of opposite polarity for a failure, since the feeding current flows through the coil 9, and the diode 7, the contact 8 is opened, and a voltage produced across the Zener diode is not applied to the amplifier 1. The similar effect is obtained by inserting a diode 11 between the amplifier 1 and the diode 7.

The magnification of the lenses and the taper of the cells are chosen so that, to the observer, the sides of the cells appear parallel, that is, the adjacent sides appear to merge into one thin wall, and the groups of value computations and price numerals at the small ends of the cells appear as continuous lines of readings. Interposed between these groups of readings are further groups of readings for extending the range of prices and values. The latter readings are brought into view by sliding the lenses and cells laterally, the original readings then being masked by the sides of the cells. The weight readings are read through the lens 22b. An incandescent lamp within the casing illuminates the price and value charts.
