Abstract: PROBLEM TO BE SOLVED: To improve more the quality of an OFDM modulation signal. SOLUTION: A signal point transmitter 14 allocates a signal point Zk ,l in a QPSK modulation circuit 18 to parallel data S100 inputted from an S/P conversion circuit 100 by changing an amplitude so as to compensate an aperture effect of a communication transmission line and each section after an IFFT circuit 104 onto a modulation signal S20. D/A converter circuits 1061 , 1062 and LPF circuits 1081 , 1082 convert complex number data zk ,m into analog form and eliminate an undesired harmonic component to generate transmission signals S1061 , S1062 . The QPSK modulation circuit 18 adopts the QPSK modulation system to generate a modulation signal S18 at an intermediate frequency band. A transmission circuit 20 converts the modulation signal S18 into a modulation signal S20 at a carrier frequency band of a communication transmission line to send it.

Abstract: PROBLEM TO BE SOLVED: To make an analyzer efficient by a constitution wherein a gas which is heated and desorbed by a plurality of lines installed in parallel is sent to a selectively introducible mechanism and only a desired gas is selected and passed there in a time- dependent manner so as to be introduced to the analyzer. SOLUTION: When a component in which a gas sample is concentrated and desorbed is analyzed, a silicon wafer analyzer(SWA) 1 is made to communicate with a cryofocus mechanism (TCT) 4 by a signal which is issued when a selector valve unit (hereafter mentioned as a valve) 2 is operated. By the progress of the cryofocus of the TCT 4, a gas chromatograph 5 starts the analytical operation of a temperature or the like. When a component in which a gas sample is heated and desorbed is introduced to the gas chromatograph 5, the valve 2 is operated, and the flaw rate of the gas sample from the SWA 1 is adjusted so as to flow in a small amount. At the same time, by a signal from a heating and desorbing autosampler (TMD) 3, the TMD 3 is made to communicate with the TCT 4.  By a signal at a time when the sample from the TCT 4 whose analysis is started is heated and desorbed, the TCT 4 is made to communicate with the gas chromatograph 5, and the gas chromatograph 5 executes an analytical operation.

The surface of the exposed portion is converted to amorphous to 1,000Angstrom  of depth. Thereafter, it is additionally etched for approx. 30sec with solution of HBr:HNO3:H2O=1:1:5 (volumetric ratio at 25 deg.C). Thus, the thin shape does not considerably depend upon the azimuth of the substrate and the groove forming direction, and the depth of the amorphous layer is correctly controlled by ion implanting.

Abstract: PURPOSE:To make it possible to omit the mechanical angle-position adjusting work by providing a turning mechanism which turns a wavelength selecting diffraction grating and a spectroscopic diffraction grating at the same time, and providing a driving motor which changes a turning angle and a resonance distance at the same time. CONSTITUTION:When a voltage is applied on a piezoelectric element 47, a resonance distance L between a laser semiconductor 32 and a diffraction grating 34 is changed. Laser light 31 passes through a body to be measured 26 and enters into a spectrum analyzing part 28 in a cabinet 21 as light to be measured 38. In the analyzing part 28, the light to be measured 38 is converted into the parallel light through a collimator 40 and thereafter cast into a spectroscopic diffraction grating 35 at an incident angle of theta2. The diffracted light is condensed on a photodetector 45 through a condenser device 42, and the optical intensity signal corresponding to the intensity of the incident light is outputted. When a driving motor 37 is driven, the diffraction gratings 34 and 35 are also turned. The wavelength lambda2 is changed in response to the change in output wavelength of the laser light 31. In this constitution, the wavelength- selecting and spectroscopic-diffraction gratings 34 and 35 are changed in synchronization. Therefor, the adjusting work can be omitted.

Filed: 1988-09-30
Abstract: PURPOSE:To make it unnecessary to increase the processing capacity of a file by dispersing and providing a position registering file at respective radio base stations. CONSTITUTION:A moving station 190 is registered in a position registering file provided at a radio base station corresponding to the radio zone to which it belongs.
