Title: Production of spin valve type thin-film element and production of thin-film magnetic head using the spin valve type thin-film element
Inventor: SAITO MASAJI
IPC: G11B5/39
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a spin valve type thin-film element which is capable of stably maintaining the magnetization of fixed magnetic layers divided to two layers in a counter parallel state by adequacy controlling the magnetic moment of two layers of these fixed magnetic layers and the direction and magnitude of the magnetic field to be impressed during heat treatment and is capable of obtaining ΔMR as high as heretofore and a process for producing a thin-film magnetic head using the spin valve type thin-film element. SOLUTION: The magnetic moment of the first fixed magnetic layer 12 is made smaller than the magnetic moment of the second fixed magnetic layer 14. In such a case, the magnetic field of 100 to 1000 Oe is impressed in a direction reverse from a direction where the magnetization of the first fixed magnetic layer is desired to be obtained or of >=5 kOe in a direction where the magnetization is desired to be obtained. As a result, the magnetization of the first fixed magnetic layer 12 and the second fixed magnetic layer 14 may be maintained in the counter parallel state.

Title: Explosion-proof type sealed battery
Inventor: TAMAI MIKITAKA
IPC: H01M50/574
Filed: 1992-12-25
Abstract: PURPOSE:To shut off current at high accuracy without affecting deposition strength. CONSTITUTION:A breaking connector 15 is connected between a valve body 2 and a power generating element 7 in a sealed battery. A breaking part 15A which is broken when a force of a predetermined level works, is provided on a part of the breaking connector 15. When the valve body 2 is deformed due to increase in the inner pressure of the battery, the breaking part 15A is broken, and the electric connection between the valve body 2 and the power generating element 7 is shut off. When the valve body is deformed, the breaking part of the breaking connector is broken instead of a conventional fused part. Since the breaking part is supposed to be broken after a force of a predetermined level works, breaking takes place certainly when the inner pressure of the battery is raised beyond the predetermined level.

In addition, in order that a receiving time in a converting element in a center of the array converter may correspond to an estimated moving distance, the speed of the ultrasonic signal in the medium is estimated. Next, through the use of a fixed receiving time and the moving speed of the ultrasonic wave, the moving distance of the ultrasonic signal to the converging point is obtained and the convergence delaying time accompanying the moving distance is calculated to calculate a convergence delaying curve.  Then, while varying the ultrasonic moving speed, a process of calculating the convergence delaying curve is repeatedly executed to obtain the luminance and contrast of ultrasonic video.
