Abstract: PURPOSE:To exactly and easily perform the laying work of a hurdle dyke at construction site as well as permit the mass-production of constituent parts, e.g., strut, side plates, and bottom plate, each having specific structures, for the hurdle dyke. CONSTITUTION:A trench of a specific cross section is excavated in the ground 5, struts 2 are set at fixed intervals in the trench, and a bottom plate 4 is inserted sideways and laid in the part of a bottom receiving beam 2A. Also, in the part of a strut receiving beam 2B, side plates 3 are inserted and fixed from above. In this case, the bottom plate 4 and the side plates 3 are coupled with the flanges F of each shape steel member constituting the struct 2. In this way, the operations are orderly repeated to form the hurdle dyke. The thickness H of the bottom plate 4 and the side plates 3 is made smaller than the distance F' between the flanges. After the laying work, the bottom plate 4 is pushed upwards and the side plates 3 are pushed inwards and pressed on the internal flange F when embbdded. As a result, in the hurdle dyke thus laid, water coming from outside flows into between the side plates and goes out.

Title: Terminal base device for circuit breaker
Inventor: HOSOGAI SETSUO
IPC: H01H73/20
Filed: 1990-02-09
Abstract: PURPOSE:To dispense with wiring space by providing a neck part on the halfway of a male tab terminal, and providing a slant at the position opposite to the neck part, in rear of the terminal base. CONSTITUTION:Terminals 11 are press-fit to a terminal base 3, respectively, by inserting a pair of projections 11d of male tab terminals 11 into the terminal base 3 until they abut on the middle bottoms 3e of it. Next, holding the top 11a of the terminal 11 from the rear side, twisting is applied in the horizontal direction. At this time, the terminal 11 is twisted at the neck part 11e, and the angle of the shoulder 11f of the bottom of this neckpart interferes with the slant 3h in rear of the terminal 3 so that it runs on it. By this work, the upward C slip out of the terminal 11 can be prevented surely, and also the looseness of the terminal 11 can be prevented. This obviates the necessity of taking the wiring space of an external lead wire wide in the width direction of the terminal base, and the interval at the time of juxtaposition of circuit breakers can be confined to the minimum.
