Title: Fire alarm
Inventor: OKAYAMA YOSHIAKI
IPC: G08B17/00
Filed: 1988-12-02
Abstract: PURPOSE:To attain highly accurate fire decision by weighting the combination of I/O values shown in a definition table so that errors can be reduced. CONSTITUTION:Data are manually inputted to a storage area RAM 12 of the definition table and a weighting value is stored in a storage area RAM 13 by a net structure forming program based upon the inputted data. Namely, the contents of the definition table are teached to a signal processing network by adjusting the weighting value so that errors are most reduced in the I/O values shown in the definition table. Once the signal processing network is formed, the signal processing network can output desirable output values to all input values, so that the device can correspond also to the combination of plural time-sequential detecting information patterns not defined in the definition table and the value of desired fire information (fire accuracy, dangerousness, accuracy of burning fire, etc.). Consequently, detailed fire decision based upon the time-sequential detecting information can be attained.

Title: Broadcasting system discriminating method
Inventor: UCHIYAMA SHINICHI
IPC: H04N9/00
Filed: 1994-11-14
Abstract: PURPOSE: To discriminate the broadcasting system of an input video signal corresponding to two crystal switching control signals even at the same vertical synchronizing signal frequency by deciding a phase locked state to the color burst signal of a crystal oscillator. CONSTITUTION: When a switch circuit 14 selects any crystal different from the broadcasting system of the input video signal, there is no color burst signal in the frequency variable range of a VXO 10 so that the phases of an output signal from the VXO 10 and the burst signal can not be locked but a killer discriminating circuit 22 can detect a black-and-white signal state. When the selected crystal is matched with the broadcasting system, the phases are locked, the circuit 22 is turned to a color signal detecting state, a reset circuit 23 stops the operation of a monostable multivibrator circuit 24, and no pulse is outputted to a system discriminating circuit 25. Therefore, the circuit 25 is fixed in the state of matching the input video signal broadcasting system and the broadcasting system of the crystal selected by the circuit 14.  When the circuit 22 detects black-and-white, the circuit 14 switch crystal 12 and 13 at every one second and at the time of crystal matched with the input signal, the circuit 23 stops the circuit 24 and fixes that broadcasting system.

Inventor: TSUNEHIRO NAOJI
IPC: H04B1/04
Filed: 1990-11-09
Abstract: PURPOSE:To attain more flexible, broad and accurate transmission power control by applying fuzzy set processing to a power control range of a power module so as to implement ambiguity separation and implementing fuzzy deduction based on a control rule corresponding to each fuzzy set subjected to ambiguity separation. CONSTITUTION:An output power of a power module 11 outputting a transmission power subject to power control is detected and a deviation between the output power and an object output power level is calculated. Then a power control range of the power module 11 is subject to fuzzy set processing to apply ambiguity separation to each based on the calculated deviation and a power control manipulated variable with respect to the output power. Fuzzy deduction is implemented based on a control rule corresponding to each fuzzy set subject to ambiguity separation to decide a power control variable of a transmission power of next stage. Thus, the more flexible, broad and accurate transmission power control is applied even to a change in the dynamic characteristic due to dispersion in ambient temperature and of quality of each component.
