IPC: G06T5/00
Filed: 1989-07-07
Abstract: PURPOSE:To suppress the deterioration of signal except the noise by obtaining a corrected noise estimate image by applying the inverse Fourier transform to a spectrum image processed by a threshold value processing means and subtracting the corrected noise estimate image from a deteriorated image in order to obtain a corrected image. CONSTITUTION:An image correcting device is provided with a noise estimate image calculation means 2, a Fourier transform means 3, a threshold value processing means 4, an inverse Fourier transform means 5, a corrected image calculation means 6. A noise estimate signal (n') is produced from a deteriorated image (g) and undergoes the Fourier transform for each area as well as a thresh old value process. At the same time, the inverse Fourier transform is applied to the signal (n') for production of a corrected noise estimate image (n''). Then the image (n'') is subtracted from the image (g) for production of a corrected image f'' = g - n''. Thus it is possible to suppress the deterioration of signals except the noise and to obtain a corrected image approximate to an ideal image.

Title: Seed used for slope seeding and seeding
Inventor: YOSHIDA HIROSHI
IPC: E02D17/20
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain the subject seed capable of being prevented from rebounding from a vegetation substrate by attaching a thready material on the surface. SOLUTION: This seed 10 used for a slope seeding method by spraying a vegetation substrate containing the seed and a growing base material has thready material 20 attached to the surface of the seed 10 for example by an adhesive, etc., to prevent the seed 10 rebounded by the spray from dropping. The thready material 20 attached to the surface of the seed 10 at one end is extend long from the surface of the seed 10. When the seed 10 is rebounded and dispersed by the impact of the spraying of the vegetation substrate and begins dropping on the slope, the seed 10 drops while dragging the thready material 20. As the result, the dropping speed of the seed 10 is retarded by the friction resistance between the thready material and the slope, or the drop is stopped, and thereby the capture of the seed 10 rebounded by the spraying is facilitated.

Title: Differential amplifier
Inventor: HAYAKAWA MITSURU
IPC: H03F3/45
Filed: 1985-08-13
Abstract: PURPOSE:To form a differential amplifier with high power utilizing factor, less phase shift and excellent high frequency characteristic by limiting the upper limit of a DC potential of an output signal by a current source and limiting the lower limit by a base-emitter voltage of a transistor (TR) and applying feedback to a current mirror circuit. CONSTITUTION:The upper limit of the DC potential of the output signal is limited by a current source IS 3 and the lower limit is limited by the base- emitter voltage of a TR Q4. In general, since the current source IS3 consists of the current mirror using NPN TRs, the upper limit of the DC potential of the output signal is (power voltage Vcc)-(base-emitter voltage of TR) and the lower limit of the DC potential of the output signal is a voltage twice the voltage at a point A, that is, twice the base-emitter voltage of the TR. Since the DC potential Vl of the output signal has a relation as 2VBE<Vl<{(power voltage Vcc)-(base-emitter voltage of TR)}, then the utilizing efficiency of the power Vcc is improved. Since feedback is applied to the current mirror circuit, the phase shift is improved remarkably.
