Title: Signal suppression circuit
Inventor: OTANI MICHIHIKO
IPC: H04N5/208
Filed: 1992-04-08
Abstract: PURPOSE:To prevent the unsharpened contour due to excess aperture suppression and the S/N deterioration in insufficient suppression by using two constant current sources for parameters deciding the suppression rate so as to reduce the relative dispersion in the suppression rate. CONSTITUTION:A suppression control signal is inputted to an input terminal In1 and a suppression control DC voltage of a prescribed level is given to an input terminal In2. Then a collector current ratio of transistors(TRs) Q3, Q5 and a collector current ratio of TRs Q2, Q4 are identical to each other when the characteristic of the TRs is the same. Thus, since a ratio of currents flowing to diodes D1, D2 is coincident with a ratio of collector currents of TRs Q7, Q8, the suppression rate of the input signal current when it is inputted from an input terminal In3 and suppressed is outputted from an output terminal OUT1 is only two parameters of constant current sources I3, I4. Furthermore, the parameter relating to a temperature change effected onto the suppression ratio is set to kT/q (k: Boltzsman's constant, T: absolute temperature and q: charge of an electron) only and then the temperature change is reduced.

Abstract: PURPOSE:To achieve the stabilization and rationalization of quality in process control by clearly forming a clear print even when printing is applied to a molded article composed of a compsn. prepared by compounding a specific amt. of a specific compd. with a polyolefinic resin by laser beam. CONSTITUTION:The surface (smooth surface part 1 and rough surface part 2) of a molded article composed of a polyolefinic resin compsn. prepared by compounding 0.05-1.0 pts.wt. of ultramarine with 100 pts.wt. of a polyolefinic resin is irradiated with laser beam to apply printing to a printing part 3. Ultramarine is sulfur-containing sodium-aluminosilicate. Therefore, the transmission of laser beam is eliminated by the mutual action of these substances and the clear printing part 3 is formed on the surface of the molded article A by laser beam. Especially, since extremely clear printing can be formed on the rough surface part 2, even when the printing surface of the molded article A is rough, it is unnecessary to perform treatment making the rough surface smooth.
