Title: Power line carrier communication equipment
Inventor: SHINOZAKI SATOSHI
IPC: H04B1/707
Filed: 1994-04-18
Abstract: PURPOSE:To improve the S/N in a transmission mode by performing the transmission by the upper limit transmission power and then detecting a high frequency band part or comparatively high S/N after applying the weight to the part and amplifying it. CONSTITUTION:The transmission data 4 undergo the differential coding by a differential conversion part 10, and the signals of an oscillator 11 undergo the PSK modulation by a data modulation part 12. The codes scattered from a PN code production part 13 undergo the flattening processing of spectra by a spectrum shaping filter 14. The signals received from the part 12 undergo the scattering of spectra by a spectrum scattering modulation part 15, and these signal components of frequency higher than 450kHz are eliminated by an LPF 16. Then these signals are applied to a power line 3 via a signal supply part 17. An input signal is extracted by a signal extracting part 20 and only the effective frequency component of the signal is taken out by an LPF 21. The input signal of a delay circuit 22 is delayed by an extent equal to the data-1-symbol time and outputted to a multiplier 23 to undergo the multiplication. The undesired high frequency component of the multiplied signal is eliminated by a delay detection LPF 24. Then the signal is binarized by a comparator 25 and outputted as the reception data.

Title: Frequency/voltage converter
Inventor: KUBO MITSUO
IPC: H02M5/45
Filed: 1985-04-13
Abstract: PURPOSE:To control the frequency and the voltage of a wide range with a simple circuit configuration by individually constructing a main circuit and a commutation circuit with forcibly commutating GTOs. CONSTITUTION:N-phase AC power source of frequency f0 is switched (f) times at every time in the phases of the power source. The frequency F of the basic wave of the output becomes F=f/N-f0. If F is positive in the phase order in case of f/N>f0, it is reverse phase in case of f/N>f0, and DC in case of f/N=f0. When the outputs of aM sets are produced, the AC of M phase of the frequency F can be generated. In addition to the switching of the phase, a voltage is switched from an AC voltage of one amplitude to an AC voltage of other amplitude during the phase switching or between the phase switching and the phase switching to control the voltage applying time, thereby altering the output voltage of a frequency converter together with the frequency.

Abstract: PROBLEM TO BE SOLVED: To lower the resistance of a thin-film by performing a thermal process in an oxidizing gar or in a gas atmosphere which contains oxidizing gas with a thin-film which comprises a metal silicide layer containing a group V element in periodic table. SOLUTION: When a thermal process is performed at 1000 deg.C, a specific resistance value decreases both in an oxygen gas atmosphere and a nitrogen gas atmosphere, wherein the specific resistance value of the former is 32.6 μΩ.cm while that of the latter 45 μΩ.cm, with the specific resistance value of the former being 30% smaller tan the latter. When the thermal process at 1100 deg.C, the specific resistance value of the former is 25 μΩ.cm while that of the latter 35 μΩ.cm, with the specific resistance value of the former being smaller by 30% than the latter. Meanwhile, related to the count of phosphorus, atom, both the former and latter do not decrease much from 900 deg.C even when a thermal process temperature rises from 900-1100 deg.C. The decrease effect of the specific resistance value is confirmed in the thermal process at 950-1100 deg.C.  The effect at 1000-1100 deg.C is especially distinctive.

IPC: H04B10/07
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To adjust the amount light emission according to a distance between information equipment. SOLUTION: An output current 11 flows to a photodetector 3 according to the amount of received light of the photodetector 3, and the output current 11 is converted to a voltage V1 by a current/voltage conversion circuit 4.
