Title: Ac power supplying system
Inventor: TANAKA MAKOTO
IPC: H02J3/38
Filed: 1991-04-05
Abstract: PURPOSE:To prevent the occurrence of the reverse flowing phenomenon of AC power from a non-utility generator, such as fuel cell, etc., to a commercial power source when the power of a load is reduced at the time of supplying the AC power to the load by always interconnecting the commercial power source and non-utility generator with each other. CONSTITUTION:The output of a fuel cell 2 and power of a load 6 are always monitored by means of two power detectors 21 and 61. When the power of the load 6 becomes lower than the set electric energy of the batter 2, a control circuit 30 controls the output of the battery 2 by controlling a power transformer 3 connected to the battery 2. Therefore, the occurrence of a reverse flowing phenomenon can be prevented, since the cell 2 always supplies its output at a value smaller than the power of the load 6.

IPC: H01B13/02
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To avoid wire break in winding by providing multiple intersections of strands for each pitch, and twisting the strands while moving them in the longitudinal direction of a litz wire. SOLUTION: Strands 3a-3g are prepared at the same length in parallel, and twisting is applied to them. Multiple intersections of the strands 3a-3g are provided for each pitch, and the strands 3a-3g are twisted while being moved in the longitudinal direction of a litz wire to form the litz wire. Since multiple intersections exists, every two, not all, of the strands 3a-3g cross together simultaneously, and their intersections are moved in the longitudinal direction. The strand 3a first crosses the strand 3e, next the strand 3a crosses the strand 3f, then the strand 3a crosses the strands 3g, 3b, 3c, 3d in this order. The twisting angle between the strands is made constant. When the litz wire is untwisted, the lengths of the constituting strands are made nearly constant.

Filed: 1994-03-03
Abstract: PURPOSE:To lift/lower a hull by installing a float on a carriage for supporting the hull, and rotating the float around a carriage installing part as the center so as to float/sink the carriage. CONSTITUTION:A floating building berth consists of a carriage 1, which supports a hull 4 and is made of steel, wood, and the like, and a float 2 made of FRP, and the float 2 is rotated by 90 deg. around a carriage installing part 3 as the center so as to be set horizontal, and consequently, the carriage 1 is floated/ sunk, so that the hull 4 is supported on the water surface. Therefore, in application of a load to the float 2 for floating/sinking it, in the case of the fixed load, sinking quantity is increased as a cross sectional area of the float 2 to the water surface becomes smaller. In this way, the hull 4 can be lifted/lowered by means of simple action such as the rotation of the float 2.
