Title: Composite magnetic head
Inventor: HAYAKAWA MASATOSHI
IPC: G11B5/127
Filed: 1988-05-25
Abstract: PURPOSE:To obtain the composite magnetic head which does not generate large magnetic reluctance by disposing magnetic underlying layers contg. a corrosion resistant metal between thin magnetic metallic films and magnetic oxide materials. CONSTITUTION:This composite magnetic head is constituted by butting a pair of magnetic core half bodies, at least one of which is constituted of the magnetic oxide material and the thin magnetic metallic films 5, 6, against each other and forming a magnetic gap 2 to the butt surfaces of the thin magnetic metallic films.

Title: Automatic switching apparatus of high pressure gas supply
Inventor: YANAZU KATSUJI
IPC: F17C13/00
Filed: 1984-06-21
Abstract: PURPOSE:To make it possible to use a spare side high pressure gas automatically when a normal side high pressure gas is consumed by forming a flow passage for flowing out from a receiving opening to a receiving side with the displacement of an interception body from the flow out opening of the spare side high pressure gas to that of the normal side high pressure gas. CONSTITUTION:When all high pressure gas in normal side reservoir is consumed, gas pressure is dropped to zero, and only an energizing force of spring or the like is remained as a force of displacement of the interception body 6 toward the flow out opening 5 of a spare side high pressure gas. The energizing force is smaller than the gas pressure of the spare side high pressure gas, and it is impossible to maintain the interception body 6 in contact to the flow out opening 5 under presure by the energizing force only. That is, the gas pressure of a spare side reservoir becomes larger than the energizing force of an energizing means, the interception body 6 is displaced from the blow out opening 5 toward the flow out opening 4 of the normal side high pressure gas beyond a receiving opening 10, the spare side high pressure gas is flown out from the flow out opening 5 into a tubular member 1, further, a flow passage from the receiving opening 10 to the normal side is formed. Therefore, the spare side high pressure gas is flown out automatically toward the receiving side through the flow passage when the normal side high pressure gas is consumed entirely.
