IPC: H04B3/04
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To share a tilt circuit without generating any gain loss in different bands by selecting the transmission band to compensate transmission through a band selecting means and compensating the transmission with attenuation characteristics shown by the value of preset reference attenuation quantity in the selected transmission band through a transmission compensating means. SOLUTION: When a band changeover switch SEL is set to the side of 450MHz, at a serial resonance circuit part, serial resonance is performed by coils L1 and L3 and a capacitor C1 and at a parallel resonance circuit part, parallel resonance is performed by coils L2 and L4 and a capacitor C2 . When the band changeover switch SEL is set to the side of 550MHz, on the other hand, since a DC is supplied, the DC flows in the order of the coil L3 , diode D1 , resistor R2 , diode D2 and coil L2 , the diodes D1 and D2 parallelly connected to the coils L1 and L4 are conducted and the coils L1 and L4 are short-circuited. At the serial resonance circuit part, the serial resonance is performed by the coil L3 and the capacitor C1 . Thus, the tilt circuit can be shared for both frequency bands corresponding to the switch SEL.

Title: Fsk demodulator for direct conversion receiver
Inventor: MIMURA MASAHIRO
IPC: H04L27/14
Filed: 1993-09-13
Abstract: PURPOSE:To receive FSK signals at the low fluctuation index by increasing the detection number in the phase relation of I and Q baseband signals. CONSTITUTION:An I baseband signal is binarized in amplitude control amplifiers 3,5, and 6 and takes them as the trigger input of phase discrimination circuits 9-11. On the other hand, the Q baseband signal is binarized by an amplitude control amplifier 4 and takes it as the phase input of the circuits 9-11. When a code change occurs in the trigger input, the rise and fall of change is discriminated. When the rise is detected, the fine coefficient of the signal shows positive. The differential of the I signal becomes the same phase with the Q signal. The positive and negative of the differential coefficient of the I signal are compared to discriminate the mark and space of the transmission signal based on whether or not the same code can be obtained. Thus, the reception of the FSK signal at the low modulation index which is hard to obtain in demodulation based on only the information binarized near the center of the baseband signal in the conventional digital system can be performed by increasing the number of phase detection of the Q baseband signal.

Title: Directing method of light wave range finder
Inventor: TAKAHASHI TOKIO
IPC: G01S17/08
Filed: 1982-12-27
Abstract: PURPOSE:To achieve a accurate and quick facing with a target by displaying variations of the quantity of light with two different color light emitting elements. CONSTITUTION:Two light emitting diodes D1 and D2 different in color are inserted in series into a motor M in an inverted parallel relationship with each other. When the motor M rotates in the direction of damping the quantity of light, the blue light emitting diode D1 is turned on while when in the direction of enhancing it, the red light (diode D2) is emitted. When the body is turned vertically or horizontally so as to face a reflector, instantaneous flashing of the blue light emitting diode D1 indicates that the facing is not accomplished yet. So, the body is turned in the same direction until the red light emitting diode D2 flashes instantaneously and then, put back against the direction of emitting red light. Thus, the correct facing direction can be determined.
