Title: Waveform equalizer
Inventor: KURIBAYASHI HIROKI
IPC: G11B7/005
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To improve an S/N ratio without causing jitters in a read signal read from a record medium by outputting a filtering processed amplitude limit read signal limiting the amplitude level of the read signal with a prescribed amplitude limit value as an equalization corrective read signal. SOLUTION: An amplifier 4 amplifies the read signal obtained from a recording disk 3 to a required value to output the read signal R. An amplitude limit circuit 51 limits the amplitude of the signal level of this read signal R by the prescribed amplitude limit value to output it as an amplitude limit read signal RLIM. This amplitude limit value is set larger than the read signal level of the shortest recording wavelength of the shortest runlength recording data, and smaller than the read signal level of the next shorter run-length recording data. Thus, the dispersion of the read signal level before/after zero cross in the read signal is suppressed forcedly, and interference between codes doesn't occur even when sufficient high band emphasis is performed by a high band emphasis filter 52.

Abstract: PROBLEM TO BE SOLVED: To provide apparatus and method for analyzing impurities in Na which can not only analyze hydrogen contained in the Na but also accurately analyse the concentration of the other impurity. SOLUTION: The partition 2 of β-alumina applied by DC current is installed in a vessel 1 introduced with melted Na. When the Na is introduced into the vessel 1, only the Na is ionized, moved into the partition 2 of the alumina, and the other components remain in the vessel 1. Accordingly, the upper space 13 of the vessel 1 is connected to an impurity analyzer 14 to analyze the impurity. In this case, the substance contained in the solid Na can be also analyzed. Since the Na passed through the alumina has very high purity, the Na can be purified.

Title: Laser radar
Inventor: SHIGEMATSU BUNJI
IPC: G01S17/10
Filed: 1993-03-17
Abstract: PURPOSE:To enhance accuracy in measurement. CONSTITUTION:An optical pulse reflected on an object 16 in the water 18 is amplified by a photomultiplier 22 and converted into an electric signal. The signal is passed through a variable attenuator 33 and amplified through a wideband amplifier 23, then fed to a comparator 24. The comparator 24 detects the pulse and delivers the pulse as a stop signal to a time/voltage converter 25 which is actuated by an emitted optical pulse. Output from the wideband amplifier 23 is branched and passed through a diode 34 to a capacitor 35 and the voltage across the capacitor 35 is fed to a buffer 36. Consequently, average output of several tens to several thousands of emitted pulses can be obtained from the butter 36. The average output is amplified by an inverted amplifier 37 and fed to an adder 38 where an offset power is added to produce a voltage of OV or above. The voltage is applied, as a control voltage, to the electronic variable attenuator 33 through a buffer 42 thus controlling the output from an average peak level detecting section 30 to a constant level.
