Title: Vibration testing method
Inventor: YOKOTA AKIHIKO
IPC: G01M7/02
Filed: 1985-01-16
Abstract: PURPOSE:To make a memory capacity smaller, by transforming an error in a time region into an error in a frequency region by Fourier-transformation, correcting an excitation signal by means of the inverse transfer function of a system from the error, and finding the correcting amount in the time region by an inverse Fourier-transformation. CONSTITUTION:An aimed signal having the aimed waveform of a vehicle A at the location of a detector 5 is determined by measuring the output signal of the detector 5 by adding a vibration signal of a prescribed waveform to the exciter 1 of a system provided with the vehicle A, to which vibration is added from the exciter 1, and the detector 5 fitted to an optional position of the vehicle A and finding the transfer function of the system. An initial excitation signal is found on the basis of the aimed signal and transfer function and added to the exciter 1. In this case, the time region error to the aimed signal of an actually working signal detected 5 at the time is transformed into a frequency region error by Fourier- transformation and the excitation signal is corrected by means of the inverse transfer function of the system from the error amount, and then, a time region correcting amount is found by inverse Fourier-transformation. Since the time region error or its correcting amount is multiplied by a factor smaller than '1' and the multiplied value is used as the time region error or its correcting value when the excitation signal is corrected, the testing time is shortened and the required memory capacity becomes smaller.

Abstract: PURPOSE:To attain variable speed transfer without the need for a storage device with a large capacity and to attain substantial high picture quality by variable speed coding. CONSTITUTION:A picture transmitter 1T converts raw picture data received from an image pickup device 1D or the like into coded data at a variable speed coder 11T and writes the data to a storage device 3T such as an optical disk device via a buffer 221T. The coded data are read from the storage device 3T in the case of transmission and transferred to a transmission line N at a speed lower, higher or variable different from a real time transmission speed via the buffer 22T. A picture receiver 1R receives coded data from the transmission line N via a buffer 22R and writes the data to a storage device 3R. In the case of reproduction, a variable speed decoder 41R reads coded data from the storage device 3R via a buffer 21R, decodes original picture data and displays them on a display device OD or the like.

Title: Magnetoresistance element
Inventor: TAKEBAYASHI SHIGETO
IPC: H01L43/08
Filed: 1994-01-21
Abstract: PURPOSE:To obtain a magnetoresistance element composed of a multilayered film and having excellent magnetic anisotropy by forming an fine undulating structure having a specific height and width or granular fine structure having a specific grain size on the surface of a substrate. CONSTITUTION:When the surface of a substrate is finely roughened, a thin film grown on the substrate becomes to have a fine structure due to the fine roughness of the surface. When the height of the undulation is too low, the anisotropy induced in a magnetic layer becomes small and the sensitivity of a magnetoresistance element drops and, on the contrary, when the height is too high, the multilayered structure of the element becomes unstable and the element does not show any magnetoresistance. Therefore, the suitable range of the mean height of the undulation is set from 0.1nm to 500nm and that of the width is set from 0.1nm to 1,000nm. On the other hand, the grain size of the fine structure is set from 1nm to 1,000nm. As a result, a magnetoresistance element composed of a multilayered film and having excellent magnetic anisotropy can be obtained.
