Title: Metallic gasket
Inventor: SUZUKI HIDEAKI
IPC: F16J15/08
Filed: 1979-02-27
Abstract: PURPOSE: To prevent a gasket from being adversely affected by heat when the gasket is heat-treated to produce a super-high vacuum, by forming the gasket from an alloy consisting of copper, aluminum and nickel, and utilizing the thermo-elastic martensite transformation of the alloy.  
     CONSTITUTION: A gasket is formed from an alloy consisting of 12W14wt% of aluminum, 1W5wt% of nickel and the balance of copper. In this gasket, the characteristic property of the alloy of remaining in the state of elastic deformation even at high temperatures, is utilized as a function requisite for gaskets. The thermo-elastic martensite phase of said alloy, when it is at a temperature of about 200°C or higher and is free from a fastening pressure, reversely transforms into the original structure, recovering the shape before transformation. At a temperature of 200W350°C and under a fastening pressure, the transformation into martensite phase proceeds, giving a deformation, with increasing the fastening pressure beyond the elasticity limit. And when the fastening pressure is released, the deformation proceeds in a reverse direction, because of the reverse transformation of the phase. As a result, the gasket, though it is metallic, exhibits such a great elastic deformation as in rubber.

IPC: H04N1/401
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the limitation of minimum value of white reference data and to simplify the configuration of shading correcting operation circuit. SOLUTION: The data on a white reference surface are read by a scanner 1, converted to a digital image signal V11 by an A/D converter 2 and preserved in a following pixel register 3. Next, the next pixel register while reference data are outputted from the scanner 1, converted to a digital image signal V12 by the A/D converter 2 and preserved in the next pixel register 3. At such a time, the signal V11 preserved in the next picture element register 3 is transferred to a current pixel register 4. When the next white reference data are inputted, a signal V13 is inputted to the next pixel register 3, the signal V12 is inputted to the current pixel register 4, and the signal V11 is inputted to a preceding picture element register 5. From the point of time when three signals are arranged, abnormal picture element detecting processing 6 of current pixel data is performed.  The average value of pixels V11 and V13 before and after a concerned pixel is calculated, that average value is compared with the current pixel V12 and when the difference is larger than a certain set value, the current pixel V12 is regarded as an abnormal pixel but when the difference is smaller, the current pixel is regarded as a normal pixel.

Filed: 1980-02-25
Abstract: PURPOSE:To generate a speed signal without using tachogenerator, by using the output of a smoothing filter as the speed signal, and counting the number of the pulses generated by a voltage frequency converter. CONSTITUTION:When the secondary winding 101c of a resolver 101 is rotated in the forward direction by a fine mechanical angle theta deg., an error signal ERS is outputted. The ERS has a sign corresponding to the rotating direction of the secondary coil 101c, is converted into the speed signal VS which is proportional to sin(theta-alpha), where alpha=electric angle, and counts up or down a reversible counter 102a via the voltage frequency counter 110. A cosalpha generating circuit 102b and sinalpha generating circuit 102c generate the primary voltage corresponding to the contents of a counter 102a, and excite the primary windings 101a and 101b. While the secondary coil 101c is rotating at a constant speed, an error angle (theta-alpha) takes a value corresponding to the rotating speed. That is, the rotating speed is equal to the speed signal VS. In this constitution, the speed signal can be generated without using the tachogenerator and the like.
