Title: Production of optical recording medium
Inventor: KURAMOTO MAKOTO
IPC: G11B11/105
Filed: 1988-01-08
Abstract: PURPOSE:To improve recording characteristics by subjecting at least the surface layer part of a synthetic resin substrate to a heat treatment at the temp. above the temp. at which thermal deformation arises. CONSTITUTION:At least the surface layer part of the synthetic resin substrate 10 formed with guide grooves 11 is subjected to the heat treatment at the temp. above the temp. at which the thermal deformation arises. The temp. of the heating treatment is the glass transition point TG-15 deg.C or above in practicabil ity and is preferably >=(TG-5) deg.C when mass productivity is taken into considera tion. This heat treatment is preferably executed by imposing the substrate on a flat base 20 having a smooth surface. The depth of the guide grooves 11 of the substrate 10 is, therefore, reduced as desired to the depth smaller than the depth after molding. The fine ruggedness on the surface of the sub strate 10 is simultaneously removed.

Abstract: PURPOSE:To detect a target signal from a noise signal showing arbitrary noise distribution, by constituting the title apparatus of a logarithmic amplifying/antilogarithmic amplifying means, a subtraction circuit, a non-linear amplifying circuit or the like. CONSTITUTION:A logarithmic amplifying/antilogarithmic amplifying means 10 subtracts the average value <Y> of a logarithmic amplified signal Y, which is obtained by logarithmically amplifying a receiving signal X having amplitude (x), from the logarithmic amplified signal Y and further respectively outputs a logarithmic amplified/ antilogarithmic amplified signal Z obtained by antilogarithmic amplification to a square average value calculation means 20 and a means 30 calculating the square value of an average value. Next, a subtraction circuit 40 calculates a dispersion value sigma<2> on the basis of a square average value <Z<2>> and the square value <Z2> of the average value to add the same to a non-linear amplifying circuit 50 which in turn raises the dispersion value sigma<2> to k-th power (k is the arbitrary real number) to output a non-linear signal U. By this method, a target signal wherein the magnitude of the dispersion value corresponding to the target signal or non-linearly amplified dispersion value is larger than that of the dispersion value of a noise signal can be detected.

Title: Line sensor
Inventor: MAEKAWA TOSHIICHI
IPC: H04N5/335
Filed: 1988-01-08
Abstract: PURPOSE:To directly convert an optical signal to the form of a voltage and to read it by reading the potential of a connecting point between a photo-diode and a precharge MOS transistor, which executes the reverse bias of this diode, through a source floor MOS transistor to an output terminal. CONSTITUTION:Since the potential lowering, which corresponds to the photo- detecting quantity of the connecting point between photo diodes D1-Dn and precharge MOS transistors Mp1-Mpn is read in the form of the voltage as it is, it is not necessary to conventionally execute integration and the necessity of amplification can be reduced. Namely, the burden of a signal processing circuit, which processes the output of a line sensor, is decreased. Since the reading is executed by source floor circuits Ms1-Msn of high input impedance, an optical charge is prevented from being exhausted due to the reading and an error is prevented from being generated by the exhaustion.
