Abstract: PROBLEM TO BE SOLVED: To provide the master station multiplexing system for a network system that immediately copes with emergency and is suitable for building up the network system with a high operating rate by immediately switching its control without stopping the system. SOLUTION: In the master station multiplexing system, plural master stations 1a, 1b and at least one of slave stations 2a, 2b are interconnected mutually and one of plural master stations 1a, 1b is set to an operating state and when the master station in the operating state is stopped, any of the other master stations is set to an operating state and each station sends/receives data based on communication definition information to which an address including a node address denoting a physical position on a station network is registered. In this case, the same communication definition information as that stored in the master station in the operating state is stored in the other master station to set a node address of plural master stations identically to each other.

Title: Dielectric plane antenna
Inventor: FUKUZAWA SHIGEYUKI
IPC: H01Q13/08
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent the gas generated at the time of soldering from being confined in an electrode part and to stably and firmly attack a dielectric plane antenna by installing a groove crossing a ground electrode or a slit crossing the ground electrode on a surface where the ground electrode of the dielectric substrate of the dielectric plane antenna is formed. SOLUTION: The radiation electrode 11 of a size decided by a resonance frequency is formed on the surface of a dielectric substrate 10. A ground electrode 12 is formed on a whole confronting face. Grooves 17 crossing the ground electrode 12 are formed at the back of the dielectric substrate 10. The grooves 17 are formed so that they pass through the center of the dielectric substrate 10 and they extend to the end face of the substrate. It is desirable that the two grooves cross at right angles at the center. The grooves can be pulled out to four corners. When an electrode 15 connected to the radiation electrode is overlapped with the positions of the grooves, it is better to form the groove around the electrode 15. When the groove is also formed around the electrode 15, the shorting preventing effect of the electrode 15 and ground electrode 12 is realized.

Title: Rds radio receiver
Inventor: SASAKI MITSURU
IPC: H04B1/16
Filed: 1987-08-31
Abstract: PURPOSE:To attain stable detection to be immune to a noise or an electric field fluctuation by reproducing a sub-carrier used for the synchronizing detection of RDS(Radio Data System) data from the tertiary higher harmonic of the pilot signal of a stereo. CONSTITUTION:The pilot signal (19kHz) of the stereo included in a composite signal is converted to a short-shaped wave and a tertiary higher harmonic generator 10 is provided to remove the higher harmonic and to amplify it. Then, the RDS data are synchronizing-detected by the output (the signal of 57kHz of a constant amplitude). Further, in order to increase stability, the data are inputted to a phase locked loop PLL to connect a phase comparator 12, an oscillator 13 and a divider 14 in a loop shape and the output is inputted to a synchronizing detector 4. When the output level of the tertiary higher harmonic generator 10 is highly set, the sub-carrier is reproduced to correspond only to the tertiary higher harmonic. Thus, the synchronizing detection to be immune to the noise or the electric field fluctuation can be executed.

Abstract: PURPOSE:To keep tube wall temperature constant by controlling a heater current in response to an output of a comparator to which a reference value is inputted depending on the heater detection temperature and ambient temperature to control the heater under the optimum condition at any ambient temperature. CONSTITUTION:When power is applied, a microprocessor 10 turns on transistors (TRs) Tr1, Tr2 to monitor the output of a comparator 8 thereby obtaining a time (t) changed from logical 1 to 0. When the time (t) is a prescribed time t1 or below, it is recognized that the ambient temperature is high to turn on the Tr1, Tr2 and to bring the original reader to the readable state. When the temperature (t) is larger than the temperature t1 and less than a prescribed temperature t2, it is recognized that the ambient temperature is room temperature, only the Tr1 is turned on and the output of the comparator 8 is changed from logical 1 to 0 again to bring the state into the read enable state. When the temperature (t) is larger than the temperature t2, it is recognized that the ambient temperature is low, both the Tr1, Tr2 are turned off, the output of the comparator 8 is changed from logical 1 to 0 again to bring the state into the read enable state.
