Title: Single oscillator fsk pulse radar transmitter-receiver
Inventor: POORU EICHI DANENBAAGU
IPC: G01S13/10
Filed: 1991-07-17
Abstract: PURPOSE: To process correctly a laser signal with a single oscillator by using a radio-frequency oscillator manufactured from a gallium element in combination with a varactor diode. CONSTITUTION: The output of a radio-frequency oscillator 11 operated in association with a varactor diode operated by a modulation pulse 13 comes to the transmitter-receiver circulator 19 via an electric power amplifier 17, and reaches a dual-purpose antenna 21. Echo received by the antenna 21 returns to the circulator 19. The circulator 19 operates to send these signals to a low noise radio-frequency amplifier 23, and then to a balance mixer 24. Signals transmitted by the oscillator 11 is also rent to the mixer 24. A demodulation intermediate frequency is sent from the mixer 24 to an intermediate frequency amplifier 28 and amplified to produce a video output that is led to a signal process system. By manufacturing the oscillator 11 from gallium arusenic, the frequency is made significantly so stable and deviated extremely quickly that a short laser pulse can be transmitted.

IPC: H04R3/00
Filed: 1982-11-15
Abstract: PURPOSE:To improve the characteristic of low frequency sound reproduction without using special construction and lowering the efficiency by providing a feedback microphone provided on a cabinet, detecting the reproduced sound of a speaker and controlling the speaker. CONSTITUTION:The sound radiated from the speaker 4 is detected by the microphone 7 provided in front of the cabinet where the speaker 4 is accommodated and the detected signal is fed back to an inverting input of a power amplifier 3 via a feedback circuit 5'. Since the microphone 7 detects a signal proportional to the acceleration of the speaker 4, accelerating feedback is applied. Even if the microphone 7 is parted from the front of the speaker 4 as shown in Figure, the reproduced sound pressure of the speaker 4 is detected correctly, the directivity of the speaker 4 at a low sound frequency is nondirectional, difference is only 1-3dB between the axis of the speaker and the surrounding of the speaker, and since the wavelength is long, the wave front is uniform in a wide range and the phase shift is less and negligible.

Abstract: PURPOSE:To measure radiation concentration by a simple system over a wide range by controlling a decrease in concentration by dilution and a flow rate through the opening and closing operation of plural control valves when the radiation in the fluid in piping reaches a high or low concentration value. CONSTITUTION:While solenoid valves 15 and 17 are closed and opened, exhaust gas is accumulated in a gas sampler 7 from sampling piping 25 and a measurement system 3 counts pulse signals outputted by a GM detector 5a according to the concentration in radiation in the exhaust gas in the sampler 7 and outputs the result to a computer 1.

Title: Tension control method at tapeless splicing
Inventor: OMAE TAKASHI
IPC: B41F33/06
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To make tension control so that no excessive tension variation is generated in a web by changing over the old shaft rotation control from a tension control into constant torque control after the web contacts with a new bobbin, and continuing the tension control as rotation control for the new shaft. SOLUTION: A web 1 is moved by a motion guide roll 45 in the condition that both an old shaft 5a and a new shaft 5b are in tension control, and contacting is generated in such a way as embracing a new bobbin 4b. At this time, the tension of the web 1 at a tension sensing means 71 is kept in a controlled state, and no excessive tension variation will be generated. A drive motor 70a for driving the old shaft 5a is changed over to the constant torque operation at a specified timing after the web 1 comes in contact with the new bobbin 4b. Accordingly the tension of the web 1 running between the new bobbin 4b and old bobbin 4a becomes an approx. constant value complying with the constant torque applied on the old shaft 5a, and no excessive tension variation will be generated and there is no risk of tightening or slackening substantially.
