Title: Peak identification method for chromatography
Inventor: NISHIMURA MASAYUKI
IPC: G01N30/86
Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to correct the change in holding time due to the deformation of a peak automatically even if the shape of the peak is deformed by overload and the like by expressing holding time as the function of a peak area based on the result of the analysis of standard samples having the different concentrations. CONSTITUTION:A holding time is expressed as holding time = a X (peak area)<1/2> + b as the function of a peak area based on the result of the analysis of at least two or more standard samples having the different concentrations. The coefficients of (a) and (b) in the expression are determined. The estimated holding time at the arbitrary peak area (i.e., the amount of a load) is computed, and the peak of a chromatograph is identified. The reason why it is assumed that the holding time can be expressed by the linear of the square root of the peak area is that the tailing peak and the leading peak indicate the shapes close to triangles as shown in the Figure. In this way, the holding time with respect to the amount of a certain load can be estimated based on the holding time obtained at the constant load amount. The error in identification due to the change in holding time when the load amount is changed can be prevented beforehand.

IPC: G11B11/10
Filed: 1991-08-09
Abstract: PURPOSE:To realize a densification recording by recording information on a recording layer, transferring information on a memory layer, transferring information of memory layer while heating up a reproduction layer, reading out the information on the reproduction layer, and completing the reproduction layer in an initial magnetization direction without applying an external magnetic field accompanied by cooling. CONSTITUTION:The magnetization of the reproduction layer is completed in one direction in advance, the magnetization of the recording layer is completed in one direction before recording, information is recorded in a recording layer, and the information is transferred to the memory layer. At the reproduction, the reproduction layer is heated up, the information on the memory layer is transferred to the reproduction layer, and the information on the reproduction layer is read out. Without applying the external magnetic field accompanied by the cooling after the reading, the direction of the reproduction layer is completed in an initial magnetization direction. After the reading, the magnetization of the reproduction layer becomes like an initial state, so that no signal is recorded in a track during reproduction and the adjacent track. Therefore, even when a signal whose recording pitch is narrower than the spot diameter, the reproduction can be performed by the single signal, enabling a densification recording.

Title: Radar receiver
Inventor: HAMATSU KIYOUSUKE
IPC: G01S7/285
Filed: 1986-08-27
Abstract: PURPOSE:To obtain a radar receiver capable of quantitatively determining even the level of a faint received signal by combining the output of a linear characteristic amplifier system for processing the faint received signal and that of a logarithmic characteristic amplifier system for processing a high level received signal. CONSTITUTION:An IF filter 3, a logarithmic characteristic amplifier 4, a video distributor 5 and an A/D converter 6 compose a logarithmic characteristic amplifier system. An IF attenuator 7, a phase detector 8, A/D converters 9 and 9a, multipliers 10 and 10a, a calculator 11 for conducting an absolute value calculation and a multiplier 12 compose a linear characteristic amplifier system. A signal at a high radar receiving signal level is processed by the logarithmic characteristic amplifier system to be outputted as a signal (d). A signal at a low radar receiving level is processed by the linear characteristic amplifier system to be outputted as a signal (e). The signals (d) and (e) are combined by a combining unit 13. Thus, since a linearity can be improved without reducing a dynamic range, the radar receiving signal levels can be quantitatively determined in a stable condition regardless of the radar receiving signal levels.
