Filed: 1995-01-26
Abstract: PURPOSE: To remove the water reducing the degree of vacuum in a mass spectrometer and prevent the occurrence of noises by introducing a passage switching mechanism between a trap column and the mass spectrometer. CONSTITUTION: The sample guided from an injector (f) is fed by a liquid feed pump A via a pipe and flows through a valve 1 → a valve 2 → a three-way joint (e) → a trap column (d) and is trapped. After trapping is completed, the valves are switched, the water from a liquid feed pump B flows through the three-way joint (e) → a valve 3 → the trap column (d), and the nonvolatile salt in the trap column (d) is washed away. After washing is completed, an organic solvent from a liquid feed pump C passes through the valve 1 → valve 3 → trap column (d) to sweep away the water in the trap column (d), then the sample is eluted. Water and the sample + organic solvent flow from the trap column (d) to the valve 3 →valve 2 in this order.  The position of the valve 2 is switched, water is poured into a drain, and the sample is guided into a mass spectrometer. These valves 1, 2, 3 are controlled manually, for example.

Abstract: PROBLEM TO BE SOLVED: To improve the output characteristics, such as the number and intensity of the peak wavelength of wavelength multiplexing signal light rays by using an exciting light generating section for generating exciting light and an optical fiber for suppressing stimulated Brillouin scattering for a wavelength multiplexing light source. SOLUTION: The wavelength multiplexing light source comprises the exciting light generating section 1 which consists of first and second signal light generators 3a, 3b for generating the signal light and a multiplexer 4 multiplexing there signal light rays with each other and outputs the multiplexed light as the exciting light and the optical fiber 2 for suppressing the stimulated Brillouin scattering(SBS). The signal light rays generated by the first and second signal light generators 3a, 3b of such wavelength multiplexing light source are multiplexed by the multiplexer 4. The light of the peak wavelength different from the peak wavelength of the exciting light is generated by the nonlinear optical effect of the optical fiber 2 for suppressing the SBS as the exciting light.  The light of the different peak wavelengths is further generated by the interaction of these light rays with each other. Then, the wavelength multiplexing signal light rays having the many peak wavelengths may be outputted from this light source.

Title: Picture reader
Inventor: WATAZUMI TERUHIRO
IPC: H04N1/028
Filed: 1985-01-25
Abstract: PURPOSE:To remove the influence due to the fluctuation of a sampling pulse period by making an A/D reference voltage generator change the quantizing unit of conversion in an A/D converter in accordance with the period of the sampling pulse. CONSTITUTION:In case of the long sampling pulse period, an A/D reference voltage outputted from the A/D reference voltage generator 13 becomes a large value V1, whereas in case of the short period, said voltage becomes a small value V2. In case of the long period, the exposing time of a CCD sensor 3 becomes longer and its analog output becomes larger, and therefore a digital value, which is A/D-converted by the voltage V1, is decreased and becomes the same value as a converted value in case of an average period. In case of the short period, the voltage equals to the converted value of the average period, whereby the titled device is free of the fluctuation of the sampling pulse period.

Filed: 1979-02-02
Abstract: PURPOSE:To secure the accurate measurement althrough the reception pulse may have the instantaneous fluctuation, by stopping properly the frequency correcting action to the oscillator. CONSTITUTION:Oscillator 15 is connected to time difference detector circuit 19 via integrating circuit 22, correction stopping circuit 30 plus detector 24 which detects that the time difference between the reception detection pulse and the delay pulse is larger than the fixed level. As a result, in case the detection reception pulse of the reception circuit is generated large before or after the output pulse of the delay circuit, the output voltage of circuit 9 increases to the positive or negative side. And then the output of comparator 25 or 26 features a high level; while the output of inverter 32 features a low level each. Thus the integrating output of circuit 22 holds the hitherto integrating value with switch 31 being connected to the earth side althrough the sampling signal may be applied to terminal 34. And accordingly, no correction is given to oscillator 15 althrough the detection timing has the sudden change, thus eliminating the erroneous measurement.

The image of the reprint is irradiated with light having the high degree of the diffusion and therefore, the flaws of the image described above are obscured on the print (on photographic paper 48).  On the other hand, the image of the simultaneous print is irradiated with the light of the low degree of the diffusion and, therefore, the rapid exposure is possible.
