Title: Approximate superconductor
Inventor: OKADA KOJI
IPC: H01B12/00
Filed: 1990-02-01
Abstract: PURPOSE:To obtain the approximate superconductor having an extremely low resistivity at a fixed temp., especially at room temp., by incorporating Rb or Cs into the superconductor as its component. CONSTITUTION:This is an oxide ceramic-based approximate superconductor contg. rubidium and/or cesium as its component. The electric resistance is reduced as the contents of rubidium and cesium are increased, however the concn. thereof is not limited. The superconductor can be prepared in the form of wire, thin film, rod or in the angular form. The superconductivity of this type is obtained as the turbulence in the atom lattice around a certain lightweight element including the detachment of the outermost-shell electron due to the impact of an electron group along with the distortion of the lattice under the steric conditions and the effect of a free electron group on the adhesion and retentivity of a certain element under vibration. If a superconductor at a high temp., especially at room temp., is wanted, a more lightweight and important element having a transition property such as sodium, potassium, scandium, beryllium and magnesium has to be used.

Abstract: PURPOSE:To obtain data completed with clock synchronization from the start to the end of the data by completing the clock synchronization in the 1st step and interpolating the data again while keeping the synchronizing state even after the step is switched to the 2nd step. CONSTITUTION:A sample value is inputted sequentially in an interpolation filter 1 and a signal waveform before the sampling is recovered at its output terminal 300. The signal waveform is fed to a clock control circuit 2, where the clock synchronization is taken. After N sets of samples sufficient to complete the clock synchronization is inputted by the clock control circuit 2, the switch 4 is changed over to the position of a terminal 42 and the interpolation filter 1 inputs a value outputted in the opposite order to that stored from a storage circuit 3. In this case, when the sample value series in the interpolation filter 1 is opposite to the series just before the switch 4 is changed over, the phase is shifted by the control circuit 5 to attain the same value obtained just before.

Abstract: PURPOSE:To stably obtain a high-purity and high-quality crystal film by previously heating an InP substrate while supplying gaseous PH2 to remove impurities at the time of growing a crystal on the substrate in a vapor phase. CONSTITUTION:An InP single crystal epitaxial layer is grown on the InP substrate by the MVCVD method (an organometallic chemical vapor growth method) to make a semiconductor device such as a photodiode. In this case, gaseous PH2 is supplied into a reaction furnace at the rate of 5X10<-3>mol/min when the substrate is heated at 200-300 deg.C before the crystal growth is started. The substrate is then heated to >=700 deg.C, heat-treated, and then cooled to a desired temp. Trimethylindium, etc., are then introduced to grow a crystal. By this method, the impurities deposited on the substrate surface are removed by the active P generated by the thermal decomposition of PH2 with good reproducibility.
