Title: Method and apparatus for interpolation of scanning lines of television
Inventor: HON SUN HOON
IPC: H04N7/01
Filed: 1992-12-28
Abstract: PURPOSE: To solve problems such as deterioration in line structure, line fickler and reduction in vertical resolution due to deficient scanning line number by timewise compressing an obtained interpolation signal and an input video signal and selecting and scanning both compressed signals. CONSTITUTION: A television video signal Vi (Y/C, R, G, B) is given to a scanning line interpolation device 10, the interpolation device 10 generates an interpolation signal and a time compressor 20 compresses the signal by 1/2 timewise. On the other hand, a time compressor 30 compresses the video signal Vi by 1/2 timewise. An output signal of the compressor 30 is selected when a switch device 40 is thrown to an original signal position and an output signal of the compressor 20 is selected when the switch device 40 is thrown to an interpolation signal position, and the selected signal is scanned to double the number of television scanning lines. In this case, the interpolation device 10 receives the video signal Vi to obtain the rate of change in horizontal, vertical and diagonal line directions.  The interpolation signal is obtained from a signal of the component having a least rate of change by taking a weight into account, which is obtained by an IIR filter in response to the least rate of change.

Title: Vibration absorber
Inventor: BAILEY DONALD C
IPC: F16F7/108
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a vibration absorber capable of changing the resonance frequency thereof by following a change of the vibration frequency to be generated with a change of the engine speed of aircraft. SOLUTION: In a vibration lower device having a mount 4o to be fitted to a vibrator such as an airframe of air plane, a plate 28 is separated from the mount 40 by a block 54. A first elastic link 60 is compressed between the block body 54 and the mount 40. A second link 62 is compressed between the block body 54 and the plate 28. The link 62 works as a spring having rigidity for determining the resonance I frequency for vibrating the block body 54. Vibration of the vibrator is absorbed by the movement of the block body 54 for absorbing the vibration energy, and the absorption of the vibration energy becomes the minimum when the block body 54 resonates at the vibration frequency. A controller senses vibration of the vibrator, and operates a mechanism for changing a space between the mount 40 and the plate 28 so as to adjust the rigidity of the spring.  Rigidity of the spring is changed till the resonance frequency of the block body 54 is adjusted at the vibration frequency of the vibrator.

Title: Circuit structure
Inventor: MIYAMOTO KENICHI
IPC: H01F27/02
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacture cost of a device while protecting a coil. SOLUTION: Two protection cases 46 each containing a coil are placed on a printed circuit board 42 to surround an adjustment coil and a stator coil 48 using a thick wire. A gap is placed to part of a winding of the adjustment coil 44 to adjust the oscillation frequency or the tuning frequency of an RF tuning circuit 18. Since the protection case 46 and the stator coil 48 are placed at a relation of position to surround the adjustment coil 44, the adjustment coil 44 is sufficiently protected. The manufacture cost of a device such as a radio receiver is not increased because the arrangement of the protection case 46 and the stator coil 48 has only to be changed to ensure the relation of position surrounding the adjustment coil 44.

Title: Method for specifying unstable block field in collapsing rock ground
Inventor: OSATO YOSHIO
IPC: G01V1/00
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To accurately specify unstable block field by measuring the horizontal component of fine move constantly at a plurality of depths in a rock ground and specifying an unstable block field part according to a vibration form based on the measurement. SOLUTION: A drilling hole 1 is punched to the inclined surface of a rock ground that may collapse, and a compact slight movement meter is inserted inside and is fixed to a hole wall 1a at a specific depth. Then, the constant slight movement at that depth is measured and a horizontal constituent is amplified, and the dominant frequency of the horizontal vibration and its amplitude (peak value) at a measurement point are calculated and recorded by a frequency analyzer.  This sort of measurement and operation/recording are made by successively changing the installation depth of the compact slight movement meter, namely the depth of measurement points A-D, and stability and instability at the measurement points A-D are judged from the difference in relative vibration property in a depthwise direction (relative value of a prominent frequency and its peak value), thus specifying an unstable block field part.
