Patent JP-H03254508-A (JP)
Title: Microwave receiver
Inventor: SHIRAI TADAO
IPC: H03C3/00
Filed: 1990-03-05
Abstract: PURPOSE:To eliminate a local oscillator and to prevent a local oscillation signal component from leaking into an output signal by applying amplitude modulation (or phase modulation) to a microwave input signal with a switching source signal, amplifying the modulated signal as a microwave detected signal and applying phase detection (or detection). CONSTITUTION:A switching amplitude modulator 2 amplitude-modulates a microwave input signal IN coming from a microwave input terminal 3 with a switching source signal SSW whose frequency is fSW from a switching source oscillator 1. When an output signal component is detected by a microwave detector 3, a signal whose frequency is fSW the same as the frequency of the switching source signal SSW is generated. The signal is amplified by an intermediate frequency amplifier 4, and subject to phase detection at a phase detector 6 by using the original switching source signal SSW as a reference signal and the phase of the reference signal is matched with the phase of the signal from the intermediate frequency amplifier 4 by passing the reference signal through the phase shifter 5. Even when the microwave input signal IN in the presence only is modulated by the switching amplitude modulator 2, an output signal VD of the phase detector 6 appears, from which the DC component and an AC component in a band of the phase detector 6 are detected.

Title: Spectrum analyzer
Inventor: SHIRASAKI MASATAKA
IPC: G01H9/00
Filed: 1983-03-30
Abstract: PURPOSE:To improve sensitivity and accuracy in analysis by passing an ultrasonic wave through a transparent flat plate in parallel therewith and in one direction, passing the same through a polarizer and the transparent flat plate, passing the polarized light having a prescribed polarizing state through the transparent flat plate then passing the same through a wavelength plate and an analyzer and drawing out the diffracted light. CONSTITUTION:An ultrasonic wave 4 of a certain frequency in parallel with, for example, an arrow A direction is kept passed through a transparent flat plate 1. The strain of a specific period is then exerted on the plate 1. A polarizer 2 is a kind of filter permitting the passage of only the light having a specific oscillation plane and therefore if light 5 is passed through the polarizer 2, the linearly polarized light is obtd. When the linearly polarized light is passed through the plate 1, double refractions are generated on account of the strain by the wave 4 applied to the plate 1 and the flat plate acts as a kind of wavelength plate, then the light past the plate 1 changes to another polarizing state. More specifically, if the light past the polarizer 2 is passed through the plate 1, said light is divided to the linearly polarized light having the planes of polarization perpendicular to each other by the double refraction. Such linearly polarized light passes the plate 1. The light past the plate 1 passes further an analyzer 3, by which diffracted light 6 is drawn.
