Abstract: PURPOSE:To obtain a creepage distance easily by installing a core cover around a core, locating intermediate walls between a core and thick parts which have terminals. CONSTITUTION:A core 7 is incorporated into a coil bobbin 1 around which a coil 6 is wound and a pair of core covers 8 are inserted into each other through a groove 8h with the core 7 put between covering the core 7. At that time, an edge of an arm 8c is inserted into the groove 8h of an arm 8b and a protruding part 8i is set into a matching hole 8j. In this case, a creepage distance between the core 7 and a terminal 5 is obtained since an intermediate wall 8g of each core cover 8 is located between an under face of the core 7 and an upper face of a thick part 4. External walls 8e and side walls 8f cover the coil bobbin 1 and an edge 5a, which is a part of a wiring section of the terminal 5, is therefore covered with the external wall 8e and the side wall 8f, in other words, this edge can be protected. Because of this, a wire cutting at this point can be avoided.

Title: Pipe type tower
Inventor: TAKAHASHI TADAHIRO
IPC: E04H12/10
Filed: 1994-03-01
Abstract: PURPOSE:To reduce weight, and to prevent the internal corrosion of a pipe type tower component by filling a steel pipe and the inside of the steel pipe with foamed aluminum packings or further filling the inside of the steel pipe with the foamed aluminum packings in which high-strength fibers are mixed, in a pipe type tower member. CONSTITUTION:A steel pipe 2 and the inside of the steel pipe 2 are felled with foamed aluminum packings 3 or further filled with packings in which high- strength fibers are mixed with the foamed aluminum packings, thus constituting a pipe type tower member (a main column). The intrusion of moisture into the steel pipe 2 as the main member of a pipe type tower is prevented, thus obviating corrosion. The weight of the pipe type tower can be made much smaller than that of a conventional concrete-filled steel pipe. Flexural rigidity is increased, and a distortion to the member of amplitude by a Karman's vortex can be reduced. The high-strength fibers are further mixed with the foamed aluminum packings thus allowing the absorption of the distortion by thermal expansion.

Title: Heating device
Inventor: MUTO YOSHIO
IPC: F24D3/10
Filed: 1989-02-10
Abstract: PURPOSE:To prevent a heating medium from being boiled in a heat exchanger by a method wherein a burner is actuated after the opening, responding to an operation signal from a control device on the indoor side, of a heating medium feed valve is increased to an enough value. CONSTITUTION:When the one of control devices 30A and 30B on the indoor side outputs an operation signal and a relay switch is turned ON, heating medium feed valves 10 or 11 responding to an operation signal therefrom is opened. Further, a burner 2 and a circulating pump 9 are actuated in a delay by a time necessary to opening of the heating medium feed valves 10 and 11. Thus, a heated heating medium is fed only to a radiator by which necessary heating is effected, useless heat radiation can be prevented from occurring, and by circulating a heated heating medium simultaneously with the starting of combustion, a heating medium is prevented from being boiled in a heat exchanger 3. Since the heating medium feed valves 10 and 11 are opened before the starting of the circulating pump 9, water hammer noise can be prevented from generation through reduction of a difference in. a pressure between heating medium circulating passages C before and after the heating medium feed valve.
