IPC: H04N5/217
Filed: 1990-07-25
Abstract: PURPOSE:To quicken the filtering by attaining 'elimination of ghost reproduction' by an 'equalizing/reproduction system' for a frequency region. CONSTITUTION:A waveform (x) deteriorated by ghost is inputted to an input terminal 10, a DFT 120 converts the signal into a frequency spectrum X and it is given to an equalizer 110, an output Y is converted into a time waveform (y) by an IDFT 130 and it is outputted to an output terminal 20. On the other hand, the signal Y is given to a reproducing device 210, its output Z is converted into a time waveform (z) by an IDFT 220 and a difference (e) with the input (x) is obtained by a subtractor 50 and a transfer function revision device 300 uses the FLMS algorithm to revise a ghost reproduction transfer function H of the reproducing device 210 adaptively, a pseudo inverse transfer function calculation device 400 obtains a pseudo inverse transfer function F(approx.=1/H) of the transfer function H to be an equalization transfer function of the equalizer 110. Thus signal (y) resulting from IDFT processing of the output Y is an equalized waveform from which ghost is eliminated.

Title: Dimension measuring device
Inventor: KOBAYASHI MASAAKI
IPC: G01B21/06
Filed: 1992-06-29
Abstract: PURPOSE:To compensate a measurement value and to measure true length and width of a freight by providing various kinds of measuring mechanisms and operation mechanisms of the freight length, freight width, and inclination angle. CONSTITUTION:When a freight A advances in an arrow direction which is at right angle to a drive roller 1, a flux of light between a light projection element 3a and a light reception element 3b is shielded tentatively as the freight A advances. Glare protection starts when one corner A1 of the front edge of the freight A crosses the flux of light 3c and it ends when a rear edge A2 crosses the flux of light 3c. These measurements are performed for an apparent length L' and no true length can be obtained unless an inclination angle theta is equal to 0. Also, since a light projector 4a projects a flux of light 4c toward a light receiver 1b on a vertical plane, the width of the freight A can be obtained according to the output from the light receiver 4b but the obtained value is an apparent width D'. True length L and width D can be obtained by obtaining theta and then compensating the apparent length L' and the width D' according to the inclination angle theta.

Title: Coding system
Inventor: MATSUYAMA HISASHI
IPC: H04N1/41
Filed: 1987-08-04
Abstract: PURPOSE:To compress the redundancy via a simple means and to code a still picture by allocating a specific code to a part having its density value equal to that right above when the information on about 16 gradations are coded. CONSTITUTION:A synchronizing code whose 8 bits are all equal to 0 is produced and a first data equivalent to a single vertical line is stored in a buffer memory 6 from a video memory 3. The 4 bits following the synchronizing code show the density value and at the same time the code trains added with 1 of 1 bit showing a section of the picture element are sent by an amount equal to one line. Then the following single line is read to the memory 6 and coded with compression. In this case, a compression code 01 is allocated to a picture element part having its density value equal to that of a picture element of a higher line. While the absolute value codes containing the 1+density value are allocated to other parts. Then the next line is coded with compression in the same way after a coding line is transmitted. The line length varies with coding and therefor a synchronizing code is added to the head of each line and the coding data is transmitted in case the data on a third and subsequent lines are transmitted.

Abstract: PURPOSE:To reduce the weight of a power transmission shaft and to improve vibration control ability of the shaft by providing a steel hollow shaft member as a power transmission shaft, charging viscoelastic high polymer material such as synthetic resin, fiber reinforcing synthetic resin in the hollow portion, and fixing same. CONSTITUTION:A transmission shaft 4 is disposed in the interior of an operating rod 1 connecting a prime mover 5 and a cutting edge 2.
