Title: Reflector antenna
Inventor: KIMURA YASUHIRO
IPC: H01Q17/00
Filed: 1979-09-04
Abstract: PURPOSE:To reduce the retroradiation caused at the periphery of the shadow boundary and the diffracted wave, by providing the electric wave diffusing plate at the tip of the masking shield and at the same time attaching the electric wave absorber onto the inner wall of the masking shield. CONSTITUTION:The electric wave absorber 5 is attached onto the inner wall of the masking shield 4 in an appropriate width to absorb the spill-over power of the primary radiator 3 which contributes to the radiation property around the shadow boundary. Thus the radiation property is suppressed at the shadow boundary and its periphery. And both the lengths (h) and (l) of the shield 4 and the electric wave diffusing plate 6 which are obtained from the equations 1 and 2 are effective to the entire circumference of the shield 4 and the outer circumference frame 7 in case when the radiation property of the primary radiator 3 is in the rotational symmetry. As a result, the electric field can be reduced at the tip of the shield 4 and the frame 7, and accordingly the retroradiation property can be suppressed. In the equations, D shows the aperture diameter of the reflector 2, lambda is the wavelength, i=3, 5..., N=h-H, W=(H+h)<2>-H.h, and H is the height of the frame 7 respectively.

Title: Radio receiver with tuning display
Inventor: MATSUMORI YOSHINORI
IPC: H03J3/14
Filed: 1978-09-12
Abstract: PURPOSE:To reduce the power consumption for the receiver using the cell as the power source by actuating the light emitting diode in the detuning state not in the tuning state. CONSTITUTION:The reception wave is detectes at diode 4 via antenna 1, high frequency circuit 2 and intermediate frequency circuit 3 each, and the detection output  is supplied to low frequency circuit 6 via variable resistance 5. The output of  circuit 6 is sent to earphone jack 7. Resistance 31 feeds the output of diode 4  back to circuit 3 to function to form part of the AGC circuit which controls the gain of circuit 3. When the reception signal is intensified through tuning, the output of diode 4 features the negative potential. Thus the AGC operates to lower the gain of circuit 3. In this instant, Tr 8 is turned off with no emission of light emitting diode 9 because the base of Tr 8 features the negative load. At the detuning time, the AGC does not operate contrarily with the base of Tr 8 featuting the positive potential, and as a result Tr 8 is turned of with emission secured for diode 9. At the same time, contact 71 of jack 7 lights up diode 9 to alarm for detachment of the plug.

Filed: 1990-04-27
Abstract: PURPOSE:To perform a high-speed arithmetic processing in a serial system by providing a condition part adaptation value memory where only adaptabilities of different conditions are stored to avoid repeated adaptability operation of the same condition in condition parts. CONSTITUTION:A control circuit 1 performs the processing as follows; a rule memory 2 is read out to discriminate whether the read code is a conditional processing code or not. In the case of the conditional processing code, the code in the same condition discrimination code column of the rule memory 2 is referred to discriminate the first processing or not of the same condition. When the discrimination code is '0' to discriminate the first processing, the adaptation of the condition part is calculated and the result is written in the prescribed area of a condition part adaptation value memory 3; but when it is discriminated that the same condition identification code is '1' and is not a first processing, the already calculated corresponding adaptation value is read out from the memory 3 to perform the conditional processing. Since repeated adaptation value calculation of the same condition is avoided to perform the arithmetic processing, which exists in condition parts of respective rules in common, only once.
