CONSTITUTION:After the first magnetic layer 4 contg. metallic (including alloy) magnetic powder having 30-40m<2>/g specific surface area by BET method and which have 2-6mu thickness t1, is formed on a nonmagnetic substrate 1 such as polyethylene terephthalate, the second magnetic layer 5 contg. metallic (alloy) magnetic powder having 35-150m<2>/g specific surface area is formed so as to have 0.2-2mu thickness t2. Further, each of anti-magnetic forces Hc1, Hc2 of the layers 4, 5 is arranged to be Hc1<Hc2. Above one layer e.g. one layer of a magnetic metallic thin film 7, for which its anti-magnetic force Hc3 is chosen to be equal to or more than the anti-magnetic force Hc2 of the layer 5, is formed so as to have 500-1,500Angstrom  thickness t3 on the layer 5.

Title: Inverter device
Inventor: YAMAZAKI SHIGEAKI
IPC: H02M7/5387
Filed: 1990-06-15
Abstract: PURPOSE:To ensure that the inverter circuit does not stop oscillation even if there is large instantaneous change of power source voltage by starting the inverter circuit when the charge of the capacitor for voltage division correspond ing to a switching element has enough charge to start the oscillation of the inverter circuit. CONSTITUTION:When the change of power source Vs voltage starts and the voltage across a capacitor C2 becomes enough voltage to start the oscillation of an inverter circuit 1, a capacitor C3 is charged through resistance R4. And at the point of time when the voltage across the capacitor C3 reaches the break- over voltage of a trigger element Q3, a base current is supplied to a transistor Q2, and an inverter circuit 1 is restarted. Accordingly, in the condition that the charge condition of the capacitor C2 is enough, the inverter circuit 1 can be started. Hereby, it can be constituted so that inverter circuit 1 does not stop the oscillation even if instantaneous large change of power source voltage occurs.

Title: Evaporative cooler
Inventor: NEMOTO TAKEO
IPC: F28D5/02
Filed: 1981-10-07
Abstract: PURPOSE:To prevent the scattering of water to the surroundings when air current is produced, by arranging heat exchanger tubes to extend substantially in a vertical direction, forming on the surface of the heat exchanger tubes many projections which extend along the axes of the tubes and are separated from each other by grooves formed therebetween, and thereby forming uniform water film over the surface of the heat exchanger tubes. CONSTITUTION:Transformer oil in a transformer 5 serving as a heat source is carried to the inside of heat exchanger tubes 1 of a cooler by means of a pump 6. On the other hand, water to be sprayed is drawn up from a water tank 10 by a pump 11 and carried to a water tray 8. Water to be sprayed, thus collected in the water tray 8, is sprayed to the heat exchanger tubes 1 through spaces formed by holes formed in the bottom plate of the water tray 8, and fins 13 and grooves 14 of the tubes 1. Since, with such an arrangement, the fins 13 function as air-flow intercepting walls when air current is produced, water passing  through the grooves 14 of the tubes 1 is protected against air flow, so that water flow is made smooth and scattering of water to the surroundings can be prevented.
