Title: Frequency analyzing method
Inventor: SUGAWARA MASAHIKO
IPC: G01R23/16
Filed: 1987-02-16
Abstract: PURPOSE:To alter a pass band or frequency without complicating a filter circuit or increasing a required space, by analyzing frequency with respect to the time series of a digital signal before analyzing frequency with respect to the time series of power value data. CONSTITUTION:Modulated noise is converted to a digital signal by an A/D converter circuit 10 to be inputted to a memory 9 and the time series of the digital signal showing a sample value at a predetermined cycle is stored in the memory 9. Subsequently, when frequency is analyzed with respect to the time series of the digital signal read from the memory 9 by a frequency analyzer 11, the effect equal to that using BPF is obtained and, as the result of the frequency analysis of a non-modulated noise component, one modulated on the basis of the modulated component is obtained. Next, a power value is calculated with respect to each result of the frequency analyzer 11 by a power calculation circuit 12 to obtain the time series of power value data. By the calculation of this power value, the frequency analytical result of the non- modulated noise component becomes one modulated by the square of the modulated component. Further, when frequency is analyzed with respect to the time series of the power value data by a frequency analyzer 13, the data proportional to the frequency analytical result of the power of a modulation signal is obtained.

Title: Oil-pressure buffer device for vehicle
Inventor: MORITA ISAMU
IPC: F16F9/54
Filed: 1979-03-19
Abstract: PURPOSE:To achieve smooth operation of a buffer device by introducing oil pressure to an auxiliary piston at the time of compression of a buffer and thereby reducing the side pressure at the time of operation of the buffer as much as possible. CONSTITUTION:At the time of compression of buffer 10, through hole 23 of valve 25 is closed, and oil pressure in chamber 20 below piston 13 is drawn into chamber 40 via space 43, linking hole 42 and path 41, and operates on auxiliary piston 33. By the reaction of this oil pressure, supporting unit 19, namely, buffer 10 is pushed back to the right in the drawing. That is, at the time of compression, the piston of the side of lower arm 37, in response to the compressed oil pressure, resists the bending force of the lower part of buffer 10 to the right in the drawing and suppresses and reduces it. By this, the side pressure to buffer 10 is suppressed and reduced as much as possible, and the smooth operation of piston 13 is secured by buffer 10, and thereby the function of the buffer is exhibited.

Through these procedures, respective interconnections 3', 5' can avoid any locally thinning parts simultaneously improving the step coverage in case of forming the insulating films 2, 4 or passivation films. Furthermore, the sectional spaces of the wirings 3', 5' are expanded by the space contained in the taper grooves 10, 11 so that the sectional space may suffice, even if the width of the wirings 3', 5' are narrowed, to enhance the electromigration resistance.
