Title: Pixel defect detector and pixel defect corrector
Inventor: FUKUSHIMA TAMOTSU
IPC: H04N5/367
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To detect the pixel defect of solid-state imaging device in the state of photographing an ordinary image, in a tri-plate type solid-state image-pickup device. SOLUTION: Color difference signals G-R and G-B are found from RGB signals by subtraction circuits 101 and 102. Change amounts Δ(G-R) and Δ(G-B) of color difference signals are formed by differential circuits 103 and 104. Then, their absolute values are calculated by absolute value circuits 105 and 106 and compared with a fixed threshold value TH by comparator circuits 107 and 108. When the change amount of color difference signal exceeds the fixed threshold value TH, the pixel defect is judged, and a control signal for correction is outputted from a subtraction circuit 109. Therefore, even for the case of an image having a much higher frequency components or colored image, the pixel defects can be detected without malfunction.

Title: Orthogonal frequency division multiple signal transmission system, transmitting device and receiving device
Inventor: KANEKO KEIICHI
IPC: H04J11/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a code error by correcting the error of an amplitude character difference and a phase characteristic difference between an I-signal and a Q-signal. SOLUTION: A transmission side transmits a known reference signal with a specified carrier among plural carriers constituting an OFDM signal, designates the carrier transmitting the known reference signal by a symbol number transmitted with the prescribed carrier, and sequentially changes and transmits them in a circle at every regular period. A reception side demodulates the reference signal in a decoding circuit 311 and a detection circuit 312 detects a transmission line characteristic. A first correction expression deviation holding circuit 313 calculates and stores a first correction expression from the detected transmission line characteristic. A first correction circuit 314 decodes the signals by using the correction expression. A second correction expression is newly calculated and corrected for the output signal of the correction circuit 314.  Thus, a high speed change characteristic can be corrected.

Title: Arm lifter for record player
Inventor: TSUKAMOTO KENKICHI
IPC: G11B3/08
Filed: 1981-03-26
Abstract: PURPOSE: To prevent a record disk and a stylus tip from damaging by achieving the successive fast, slow and fast transistion of the motion of an arm lifter without reference to whether the lifter is in upward or downward motion and putting the arm lifter in slow operation near the record disk surface.  
     CONSTITUTION: When a tone arm is lifted up from a record disk surface, a plug 60 is pressed up through the rotation of a cam shaft 70, and the 2nd cylinder 30 and the 3rd cylinder 40 are therefore pressed through a coil spring 51 to close the through-hole 21 of a cylinder 20. Once the through-hole 21 is closed, space A is closed to confine the inside air, so that the elevation speeds of the cylinders 30 and 40 increase. As the elevation advances, the part 35 of the cylinder 30 reaches the through-hole 21. Then, the air in the space A is discharged out through the part 35 and a through-hole 36 and no compressive force operates on the elevation of the cylinders 30 and 40, so that the elevation speed is increased only through the operation of springs 50 and 51. A stylus tip is lowered on the record disk surface reversely.
