Title: Phase stabilizing clock pulse generator
Inventor: NISHIZONO KAZUNORI
IPC: H03K12/00
Filed: 1992-09-07
Abstract: PURPOSE:To stablize a phase by half rectifying an AC current and discriminating the amplitude with a threshold value. CONSTITUTION:The current from an AC power source 1 is half rectified by a half wave rectifier circuit 6, the amplitude of the output is discriminated with a threshold value Vth2 by a second amplitude discrimination circuit 7, and a pulse sequence defining time exceeding the Vth2 as the pulse width is generated. The pulse repeating rate of this pulse sequence is the half of a pulse repeating rate for the output pulse sequence of an amplitude discrimination circuit 2. As a result, the phase of the front edge of the output pulse sequence is delayed rather than the output pulse sequence of a flip-flop (F/F) 4, namely, rather than the front edge of a clock pulse. The output pulse sequence of the circuit 7 is ANDed with the inverted output, which phase is inverse to the output clock pulse of the F/F 4, by an AND gate 8, and the front edge of an output waveform is impressed to the inverted input of the F/F 4 and inverted. Thus, the phase can be stablized.

Title: Automatic frequency control system
Inventor: FUJII AKIHIRO
IPC: H04N7/00
Filed: 1985-10-25
Abstract: PURPOSE:To prevent the deflection of an intermediate frequency and a distortion of a demodulating signal by stabilizing the intermediate frequency in synchronizing with a carrier of a received signal without relating to the contents of a modulation of a video signal part. CONSTITUTION:An inputted signal is converted into an intermediate frequency signal and the demodulating signal is outputted from a buffer amplifier 10 through an FM demodulator 5. The signal branched through the FM de modulation is inputted to a sample holding circuit 11 through the buffer ampli fier. The demodulating signal of the carrier sampled only during a preamble period by a switch 12 maintains a voltage until the next preamble period by a hold capacitor 13 and is impressed to a variable capacity diode 16 through a buffer amplifier 14 and a direct current amplifier 15. Thus, when the intermedi ate frequency is varied to the higher one by a variation of a local oscillator or the received input frequency, a local oscillating frequency is lowered and when it is deflected to the lower one, the local oscillating frequency is raised to stabilize the intermediate frequency and stabilize a signal processing there after. Thereby, the frequency of the carrier is kept fixed an the generation of distortion of the signal is prevented.

Title: Sodar apparatus
Inventor: KUROSAWA KIYOSHI
IPC: G01S15/88
Filed: 1983-12-19
Abstract: PURPOSE:To perform accurate measurement by reducing extraneous noise, in Doppler SODAR for performin the remote measurement of a wind direction and wind velocity on the basis of the Doppler deviation quantity of an acoustic echo signal from the atmosphere, by sending out a plurality of frequency pulse waves. CONSTITUTION:A sine wave signal is transmitted from a transmitter and converted to an acoustic pulse signal to be sent into the atmosphere from a parabolic antenna. The pulse signal is scattered by the non-uniformity of the atmospheric temp. and collected by the parabolic antenna and subsequently converted to an electric signal to measure wind velocity. At this time, two different frequencies f1, f2 are sent out by the pulse signal (c) from a receiver to receive an echo signal (d). The Doppler deviation frequencies deltaf1, deltaf2 of the received echo signal are proportional to frequencies f1, f2 and, if accurately reflected from the same scattering body, deltaf1, deltaf2 have a constant ratio f1/f2. Therefore, because f1/f2 is known, a measuring result can be accurately confirmed and accurate wind velocity data is obtained.

IPC: G06F15/17
Filed: 1989-09-14
Abstract: PURPOSE:To prevent the occurrence of the wrong control by securing such a constitution where a system storage mover provided to each cluster informs other clusters of the occurrence of an error. CONSTITUTION:An error is informed to a main processor 4-01 in a cluster 1-0 as well as to a main processor 4-00 that had actually an access. At the same time, a system storage mover 8-1 knows the error also in a cluster 1-1 and informs the main processors 4-10 and 4-11 that have no access at present of the error. In other words, the system movers 8-0 and 8-1 know the occurrence of the error respectively when an access is given to a system storage 3-k and informs all main processors 4-0j and 4-1j belonging to its own cluster of the error via the signal informing means 9-0 and 9-1.

Title: Method and apparatus for ultrasonic visualization in liquid-solid system
Inventor: TANIMOTO KENICHI
IPC: G01H9/00
Filed: 1986-10-08
Abstract: PURPOSE:To visualize the ultrasonic pulses in liquid and solid simultaneously by projecting polarized light to a sound field of the ultrasonic wave radiated into a liquid-solid system and detecting the polarized light by the refractive index of the liquid and the double refractiveness of the solid. CONSTITUTION:Light from a light source 1 is imaged in the position of a pinhole 3 and is polarized by a polarizing plate 4 to the polarized light which is then projected to a concave mirror 5. The polarized light is made into parallel light and is transmitted through an observation part 6. An ultrasonic probe 8 and a glass test piece 7 are provided in the part 6. The polarized light in water is deflected with a change in the refractive index in the underwater part by the radiation of the ultrasonic pulses from the probe 8, is reflected by a concave mirror 5' and is passed through a knife edge 9 made of the polarizing plate. Said light is visualized on a screen 11. The incident polarized light on the inside of the test piece 7 is changed in the plane of polarization by the double refractiveness (optoelastic effect) of the test piece 7 by the ultrasonic pulses and is passed through the knife edge 9 so as to be visualized on the screen 11. Since the polarized light is projected, the ultrasonic pulses in the water and the solid are simultaneously visualized and the analysis of waveforms, etc., is permitted.
