Title: Circuit arrangement for a selective signal receiver
IPC: H04Q1/457
Filed: 1973-01-04
Abstract: 1393071 Frequency analysis INTERNATIONAL STANDARD ELECTRIC CORP 4 Jan 1973 [11 Jan 1972] 559/73 Heading G4H Apparatus for the analysis of a compound A.C. signal at an input E1 consisting of several different frequencies comprises a modulator, preferably a ring modulator M, being supplied at a second input E2 with a cyclically swept frequency search signal, a plurality of storage devices S1-S8, preferably flip-flops or capacitors connected to the output of the modulator M via respective fixed contacts of a switch W so that the storage means may be cyclically connected one at a time to the output of the modulator and during the same time interval in each cycle of the sweep of the search signal. The storage devices F1-F8 each comprise an R-C integrator circuit followed by a trigger shaper circuit as input to the capacitor or flipflop. The switch W is controlled by a counter Z and the swept frequency signal is derived from generator G controlled by a saw-tooth waveform generator GS. In one embodiment, a shift register is controlled by a clock oscillator to move a "1" output through each of its 9 stages, the first eight of which are connected to operate switch W through its range of positions, and the ninth to reset an integrator which has been integrating a constant voltage source to provide the increasing ramp signal. The shift register is replaced in a second embodiment by a binary counter and binary to decimal converter. When the search frequency corresponds to one contained at the input E1, the modulator provides a D.C. output which is integrated and held as a "1" signal in the corresponding storage device. In all other events an A.C. signal of the difference frequency is provided. If only one frequency present is required, the search signal may be a single frequency and be cyclically phase swept.

Title: Oscillometric blood pressure monitor employing non uniform pressure decrementing steps
Inventor: RAMSEY III MAYNARD
IPC: A61B5/02
Filed: 1993-05-06
Abstract: The deflation of the inflatable and deflatable cuff worn by a subject during automatic sphygmomanometric measurement is accomplished in unequal size decrements and principally in larger steps than 7 Torr. Each step after detection of the initial oscillations is determined in the first instance by reference to a look-up table or en equation as a function of prevailing cuff pressure. This Base Step dimension is augmented by a factor proportional to the last oscillation amplitude, the factor being increased after detection of the maximum oscillation amplitude. A valve mechanism with at least two different effective orifice sizes is used for deflation, the smaller size effective orifice being used first, to maintain control over the decrement step rate while holding the time for decrement within a predetermined limit of 8 mSec. per Torr, i. e., maintaining the rate above 125 Torr per second. The valve mechanism can consist of two valves with unequal orifice size, or it can consist of two equal orifice size valves to be used singly for providing the effective smaller orifice, or in parallel to provide the effective larger orifice. Alternatively a single variable orifice valve can be used.

Title: Double cylindrical rotary engine
Inventor: OOHASHI KAORU
IPC: F01C1/10
Filed: 1980-01-05
Abstract: PURPOSE:To simplify the structure of a rotary engine of the type in which a double cylindrical rotor is rotated in a frame, by forming an exhaust passage and an intake passage in the rotor and exhaust ports and intake ports in the side face of the frame. CONSTITUTION:The inner surface of the frame of this engine is determined to conform to the outer contour of three circles having the same diameter which are drawn such that any one of the three cricles passes the centers of the remaining two circles. In this engine, the change in the volume of the space defined between the frame and the rotor that is caused when a double cylindrical rotor 13 is rotated in the frame is utilized. The rotor 13 is formed wtih an exhaust passage 20 and an intake passage 21. Further, intake ports 22 and exhaust ports 23 are formed in the side face of the frame. With such an arrangement, it is enabled to omit complicated valves since each cycle of engine operation proceeds when the intake port is registered with the intake passage and the exhaust port is registered with the exhaust passage.

Title: Leak detector
Inventor: YAMADA IZUMI
IPC: G01M3/24
Filed: 1988-01-06
Abstract: PURPOSE:To decide leak occurrence even when a microphone is damaged by a leak jet by providing BPFs, detectors, a leak decision device, etc. CONSTITUTION:When there is a leak at a leak point 101, its leak noise is detected by the microphone 1, whose output signal is passed through a preamplifier 3 and BPFs 41 and 51 and converted by detectors 42 and 52 into DC signals, which are inputted to the leak decision device 6. Further, the BPF 41 passes only the frequency band of the leak noise and the BPF 51, on the other hand, passes only the frequency band of an inspection signal. Then when the leak noise signal exceeds a set value, or when the inspection signal exceeds the upper limit or lower limit of two set values, the leak decision device 6 decides the leak. An inspection signal generator 2 applies the inspection signal to the microphone 1. Thus, the leak occurrence is decided.

Title: Positioning control device
Inventor: ARIGA TAKETO
IPC: G05D3/14
Filed: 1985-01-07
Abstract: PURPOSE:To prevent control accuracy from drop due to an output error of a detector by forming a quantity of state estimating circuit for estimating the quantity of state for suppressing the vibration of a load and a feedback circuit for feeding back the quantity of state estimated by the estimating circuit. CONSTITUTION:A potentiometer 4 output a signal (y) indicating the rotational position of a rotary body 3 and inputs the signal (y) to the estimating circuit 5 and a subtractor 6. The subtractor 6 outputs a signal indicating the deviation between the signal (y) and an objective position command signal and the signal is multiplied by a gain constant K4 through a coefficient multiplier 7. A signal U outputted from a subtractor 10 is inputted to a servo amplifier 11 and the estimating circuit 5. The estimating circuit 5 estimates the rotational angle and angular speed of a motor 1 on the basis of the signals U, (y) and the angular speed of the rotary body 3 and outputs signals x1-x3. The signals x1-x3 are multiplied by proper gain constants K1-K3 through respective coefficient multipliers 12-14 and the multiplied signals are inputted to the subtractors 10-8. Consequently, a positional deviation outputted from the coefficient multiplier 7 is compensated on the basis of respective quantities of state and positioning is controlled without the vibration of the rotary body 3.

Title: Snowfall monitoring device
Inventor: AONO HIROMI
IPC: E04H9/16
Filed: 1988-01-07
Abstract: PURPOSE:To monitor snowfall precisely by a system wherein a snow receiving saucer rotates automatically to drop snow when the snow lying on the saucer increases to a prescribed amount, and the frequency of the rotations is detected to control the start and stop of a snow-melting operation. CONSTITUTION:When snow is accumulated in a prescribed mount on a snow receiving saucer 1, moment of turn on the saucer 1 side surmounts moment due to a weight 4, and a lever 2 turns until it strikes against a stopper 6a positioned above. On the occasion, the snow on the snow receiving saucer 1 drops easily since the upper surface of the saucer 1 is protuberant and since an impact is given thereto when the lever strikes against the upper stopper 6a. At a time point when an angle theta s is formed after the start of the turn, a sensor 7 detects the operation, a turn interval monitoring unit 8 delivers an instruction signal for starting a snow-melting operation, and a snow-melting heat amount control unit 9 drives a snow-melting unit 10. When the snow on the saucer 1 is cleared, the weight 4 acts as a restoring device and thereby the saucer returns to the former position.
