Title: Analyzing device for frequency component
Inventor: SAKURAI MASANORI
IPC: G01R23/16
Filed: 1981-12-04
Abstract: PURPOSE:To detect the phase of a prescribed frequency component from the ratio between converted components and to detect the amplitude of the prescribed frequency  component from the square root of the square sum of the converted components, by  converting the prescribed frequency component into two component crossing at right  angles based on the correlation between the prescribed frequency component of a signal  to be measured and the waveform of a reference signal, and on the correlation of the  prescribed frequency component and a waveform obtained by shifting the phase of the  reference signal at an angle of 90 degrees. CONSTITUTION:An input signal to be measured is supplied to correlators 3 and 4. The  signal to be measured and an oscillator 11 generating a reference signal are connected  to the input ends of a multiplier 5 of the correlator 3. The signal to be measured and  a phase shifter 12 shifting the phase of the reference signal at an angle of 90 degrees  are connected to the input ends of a multiplier 8 of the correlator 4. A phase detector  13 and a level detector 14 are connected to the output ends of the correlators 3 and 4,  i.e. the output ends of integrators 7 and 10, respectively. The output voltage of a tan<-1>  operator 16 of the phase detector 13 turns to be the phase of a prescribed frequency  component. The output voltage of a squaring unit 20 of the level detector 14 turns to  be the amplitude of the prescribed frequency component.

Title: Information transmission unit for electric inspecting/ measuring vehicle
Inventor: NAGASAWA HIROKI
IPC: B60L3/00
Filed: 1985-09-04
Abstract: PURPOSE:To eliminate the need for a high voltage chamber by converting an electrical information detected by a sensor into an optical signal on the outside of an inspecting/measuring vehicle and introducing it into a measuring chamber. CONSTITUTION:An information detected by a sensor 7 is guided to an electricity- light converter 9 by a lead wire 8 as an electrical signal, and converted into an optical signal by the electricity-light converter 9. The optical signal reaches a photoelectric converter 10 fitted to a measuring chamber 5 through an optical fiber 22, and converted into the electrical signal again by the photoelectric converter 10. The information changed into the electrical signal by the photoelectric converter 10 is transmitted over an instrument 14. Accordingly, since high voltage sections are all installed outside an electric inspecting measuring car, high voltage is not lead into the electric inspecting measuring car, thus eliminating the need for a special high voltage chamber.

Title: Fet and production method thereof
Inventor: UNOSAWA HIROKIYO
IPC: H01L29/812
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a FET(field-effect transistor) which has high performance of large transconductance. SOLUTION: The FET is laminated by a buffer layer 2 consisting of an undoped GaAs, an undoped AlGaAs, and an undoped GaAs, in this order, on a GaAs substrate 1; a channel layer 3 consisting of an undoped Inx Gal-x As; an electron supply layer 4 n-type InyGal-y P; and an n-type GaAs cap layer 6. At the time of production of the FET, V-III ratio is set at 400-600 by III- family raw material gas so that the growth rate of an InGaP crystal can be at under 0.6 μm/h. While at the same time, a growth temperature is set at the range of 640-660 deg.C to meet the conditions that an Eg of the InGaP comes extremely small. As a result the InGaP crystal can grow under the conditions that a natural superlattice is most easily formed, and scattering of the interface of the electron running through the InGaP electron supply layer side within a channel can be reduced due to affections of the InGaP layer which has formed the natural superlattice. Consequently, the high-performance FET having large transconductance can be realized.
