Title: Radiowave-absorptive concrete reinforcing material and radiowave-absorptive concrete board
Inventor: KUROSAKI YUKIO
IPC: E04H9/14
Filed: 1994-06-17
Abstract: PURPOSE:To readily obtain a thin and spacious concrete panel, by knitting fine threads of chemical fibers with a large tensile strength so as to make a braid and sticking ferrite powder on the peripheral face and solidifying a reinforcing material instead of reinforcing steel rods. CONSTITUTION:Fiber fluxes 2 composed of fine threads with a large strength like polyamide fiber are kitted so as to make a braid and continuously form reinforcing materials 1. After the reinforcing materials have been forced to pass through an epoxy resin tank, ferrite powder 4 is applied. In this case, a synthetic resin core material containing ferrite powder may be fitted to the reinforcing material 1. Next, the reinforcing materials 1 are arranged to form a lattice and concrete is placed with a prestressed state. A metallic plate 6 like aluminum foil is stuck on the rear face to form a large ferrite structure 7. In this way, a large scale radiowave absorptive material can be easily obtained.

Title: Combustion apparatus
Inventor: NAKAI TAKASHI
IPC: F23D11/04
Filed: 1984-06-29
Abstract: PURPOSE:To stabilize combustion of a burner at the time of slow combustion, by controlling combustion in a burner by using a fluid element. CONSTITUTION:When kerosene is fed through an oil feed tube 11 at the same time a turbo fan 2 is driven and a rotary disk 5 is rotated, atomized oil is evaporated by a heater 6, mixed with air being fed from an air chamber 3, and is fed into a fluid element valve A. The mixed gas, fed into a fluid element valve A, is fed into combustion cups 10 and 10', respectively, and at the same time they are burned because exhaust air from right and left tubes 7a and 7b are balanced with a valve 9 is opened. When the valve 9 is closed because the balance is broken, an air is fed into the combustion cup 10 only. The opening and closing of the valve is related to the exhaust rate of kerosene, and a sequence that the valve is closed when the exhaust rate of oil is small is programmed. By this method, stabilized combustion can be taken place even during weak combustion, and a problem such as deposition of tar on a burner can be dissolved.
