Abstract: PURPOSE:To form a substance composed principally of carbon containing nitrogen and boron and boron nitride, by carrying out plasma gas-phase reaction by using a carbide gas, hydrogen, a nitrogen-compound gas, and a boride gas. CONSTITUTION:A substrate 10 is disposed on a holder 10', which is provided to a plasma-producing space 1, and then the space 1 is evacuated to <=about 1X10<-6>torr by means of a turbo-molecular pump 17, etc. Hydrogen 6 is introduced into the plasma-producing region 1 in the above state, and microwaves are applied from the outside and a magnetic field is impressed from external magnets 5, 5', by which high-density plasma is produced and the surface of the substrate 10 is cleaned. Subsequently, a carbide gas (C2H2, etc.) is introduced by means of hydrogen 6 into the plasma-producing space 1 and also a nitride gas 7, such as NH3, and a boride gas 8, such as BF3, are introduced to regulate space pressure to 1X760torr. Further, the substrate 10 is heated to about 800-1,000 deg.C by means of a heater 20 and plasma energy. By this method, a film composed principally of carbon containing nitrogen and boron and boron nitride can be formed on the substrate 10.

Title: Digital quardature detection device
Inventor: SEKIGUCHI TAKASHI
IPC: H04B14/04
Filed: 1993-07-15
Abstract: PURPOSE:To obtain a digital quadrature detection device having a highly accurate orthogonality and capable of obtaining I and Q components having a large signal to quantization noise power rate without using an A/D converter for many quantized bits. CONSTITUTION:An IF signals is over-sampled by sampling frequency more than four times of IF frequency fIF and four times of IF signal band width and quantized by the number of quantization bits smaller than the word length of required I and Q components through an A/D conversion means 4. Only a frequency component of f>0 is extracted by a narrow band complex coefficient band pass digital filter 5 to reduce the sampling frequency up to the signal band width or the like. Consequently quantized noise is reduced and the amplitude resolution of a digital signal can be maintained by extending the word lengths of the real part and imarginary part of an output signal outputted from the filter 5. A complex sine wave signal is multiplied in accordance with the center frequency of the output signal. The real part of the signal is the required in-phase component and its imargenary part is the orthogonal component.

IPC: F28D20/02
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To cancel the generation of a thermal stress due to a closed liquid phase when a latent heat storage material is melted. SOLUTION: In a latent heat storage device, a latent heat storage material 11 whose solid phase is higher in specific gravity than a liquid phase is stored in a storage tank 10 by maintaining an upper space 12. By using the phase change of the latent heat storage material 11, a heat radiation or a heat storage is carried out. In this case, heat transfer members 2 are provided by inserting at least their lower parts into the latent heat storage material 11 from an upper side. When the latent heat storage material 11 is in a solid phase, heat is applied to the heat transfer members 2 by an electric heater so that a heat generation density is higher in the upper side than that in the lower side in at least positions where the heat transfer members are inserted into the latent heat storage material 11.  Thus, the latent heat storage material 11a of the solid phase is melted along the heat transfer members 2 from its upper surface.

Title: Protecting circuit of communication equipment
Inventor: ENDO HIROYUKI
IPC: H04B3/00
Filed: 1984-08-24
Abstract: PURPOSE:To protect completely the communication equipment from the fault contact of a commercial line and a lightening surge by providing a relay between the communication equipment and a cable for communication, and detecting variation in the impedance of a heat sensitive element coupled with a protecting element thermally and closely and opening the relay. CONSTITUTION:A protection part 3 consists of the protecting element 8 which conducts when an overvoltage higher than a constant voltage is applied and the heat sensitive element 7 which is coupled with the protecting element thermally and closely. Assuming that the lightening surge or contact fault of a commercial liner occurs to the communication cable 4, the protection part 8 turns on when an external overvoltage applied to the communication cable exceeds the constant voltage of the protection part 8 and the overvoltage is grounded. At this time, the protection part 8 generates heat, so that heat sensitive element 7 decreases in impedance owing to the heat, so that the voltage of the point of connection with a resistance 14 rises. Consequently, the voltage at the connection point becomes higher than the divided voltage at a resistance 13, so a detector 10 outputs a detection signal to turn on a transistor 6, thereby driving the relay 5.

Filed: 1988-07-18
Abstract: PURPOSE:To receive a pure reception signal with a leakage transmission eliminated therefrom by adopting the constitution such that a feedback loop circuit for suppressing a transmission wave is connected to a reception antenna element. CONSTITUTION:A leakage transmission signal and a reception signal received by the reception antenna element 2 are given to a distributor 30 via a difference circuit 29, and a correlation device 26 takes correlation between a signal outputted from the distributor 30 and a transmission signal outputted from a distributor 24. An amplitude adjusting device 27 adjusts the signal from the distributor 24 by using an output of an integration device 25 so as to match the amplitude of the both and a variable phase device 28 adjusts an output of the amplitude adjustment device 27 by using the output of the integration device 25 so as to match the phases of the both. Thus, a signal having the same phase and amplitude as those of the leakage transmission signal is outputted to a difference circuit 29, where the leakage transmission signal is eliminated.
