Title: Receiver for spread spectrum communication
Inventor: YAMAMOTO MITSUO
IPC: H04J13/00
Filed: 1989-07-03
Abstract: PURPOSE:To attain sure synchronization by synchronizing a frequency synthesizing means based on an output signal of a correlation means and selecting a frequency switching period of the frequency synthesizer means to be an integral number of multiple of a PN code length. CONSTITUTION:A PN code from a PN code generator 204 of a transmitter is inputted to a frequency synthesizer 205 and plural frequency signals different in response to the PN code are outputted switchingly and sequentially. A period of a PN code and a frequency switching period of the synthesizer 205 are selected to be a multiple of an integral number so that the switching timing of an output signal of the synthesizer 205 and the PN code are synchronized. A mixer 102 of a receiver multiplies a signal from the frequency synthesizer 103 and the reception signal to apply inverse spread spectrum processing and the result is inputted to a direct spread spectrum correlation device 105. The synthesizer 103 outputs the same hopping pattern signal as the synthesizer 205. The correlation device 105 takes an output signal of the mixer 102 and the PN code and a base band output signal VBO is outputted via a demodulator 106. Thus, the synchronization is made complete.

Filed: 1994-07-25
Abstract: PURPOSE:To reduce the cost of maintenance of sliding surfaces by filling gas of a pressure meeting the absolute pressure of the molten metal in contact with sliding parts into the outer side of a pot. CONSTITUTION:A steel sheet 1 is admitted into a molten zinc bath 4 from the aperture of sliding members 3 disposed on the bottom of a vessel 2 for molten metal where the zinc is adhered thereon. The steel sheet is then pulled up, by which the galvanized steel sheet 1 is produced. The sliding members 3 movable forward and backward are installed and the spacing between the seals of the aperture and the steel sheet 1 is adequately maintained. A pressure chamber 5 of the sliding parts is so installed as to include the sliding parts 3 on the outer side of the vessel 2 for molten metal. Gaseous N2 is used for the gas and the pressure is kept at 660mmAg by a gage pressure. The temp. is 470 deg.C equal to the temp. of the molten zinc. The leakage of the molten metal 4 is thus prevented from the sliding surfaces in such a manner, by which the sliding of the members of the aperture is facilitated. As a result, the position and size of the aperture of the hollow pot are easily and cost effectively changed.

Title: Device for leading in microwave power
Inventor: SAKAMOTO YUICHI
IPC: H01J23/36
Filed: 1985-08-06
Abstract: PURPOSE:To prevent an oscillating tube from damage due to reflected microwaves by arranging a vacuum resonance cavity provided with a short plunger between a vacuum tank for generating plasma and a microwave power leading-in part. CONSTITUTION:A microwave generated from a microwave generating part is inputted from the end part of a coaxial waveguide 18 and coupled with the cavity 10 with high efficiency by adjusting the position of a short plunger 16. The cavity 10 is kept vacuum against the coaxial waveguide 18 by a dielectric window 15 and also kept at resonance state by adjusting a short plunger 11 coupled with bellows 12 arranged on the end part. A microwave in the cavity 10 is radiated from an aperture 17 to the vacuum tank 6 and plasma is generated in the vacuum tank 6. Even if the impedance in the vacuum tank 6 is changed due to the variation of plasma state, the microwave reflecting power to the microwave generating part is not increased because the resonance cavity 10 exists. Consequently, the microwave oscillating tube can be prevented from damage due to the reflected waves.
