IPC: G01G21/24
Filed: 1992-06-12
Abstract: PURPOSE: To enhance stoutness with a smaller size and a load capacity by forming a rest member, levers, coupling members and the like into a solid block as single piece by separating the parts using a narrow line cut alone. CONSTITUTION: A solid block 1 as single piece is made up of a rest member 28, levers 18 and 25, coupling members 17 and 21 and link members 2 and 3 and the portions threrebetween are formed narrower by a line cut as shown by space parts 4 and 5 or the like. Now when a force is applied on a parallerogrammatic mobile leg 11, it works on the first coupling member 17 as linking force so that the member 17 acts on a first lever 18. The lever 18 reduces the force in relation to the length of an arm and then, passing through the second coupling member 21, the force is transmitted to a second lever 25 to be further reduced. On the other hand, a compensation coil in an electromagnetic force compensation system is supported on free arms of the levers 18 and 25 and controlled so as to be always returned to the zero position thereof.  Thus, a compensation current generates a signal indicating a force to be measured to reduce the force with a smaller and stout structure thereby achieving an increase in a measuring load capacity.

Abstract: PURPOSE:To decrease the effect of burst error by converting a bit train of a delta modulation signal into a string of data word comprising prescribed number of continuous bits and transmitting it. CONSTITUTION:The delta modulation signal from a modulator 1 is converted into a parallel data of 1 word 8-bit at a serial (S) parallel (P) converting circuit 6 and then fed to a delay circuit 7.
