摘要:
A compressive hemostatic belt which is easily operable and thrown away after use, incorporates a strip (1) in the form of a nonstretch or low-stretch textile fabric, and a bag (5) expansible by being filled with fluid that is attached to the strip at a predetermined position by an attaching device. A pump (8) and a pressure gauge (9) are connected to the bag (5) attached at the predetermined position on the strip (1), so that the bag is expanded by operating the pump so as to fill the bag (5) with a suitable fluid while watching the pressure gauge (9). The bag thus presses down on an area (A) where bleeding is to be stopped.

The invention presents a compressive hemostatic belt which is easy to handle and is disposable. A balloon 5 inflatable by filling with fluid is mounted on a specific position of a strip 1 made of non-elastic or low-elastic fiber cloth or the like through mounting means, and a pump 8 and a pressure gauge 9 are connected to the balloon 5 through a check valve 6. The balloon 5 is filled with a fluid by manipulating the pump 8 while observing the pressure gauge 9 to inflate the balloon 5, so that only the area where bleeding is to be stopped is put under pressure. Since the balloon 5 is inflated only on the specified area, a piece of hard material 4 may be placed between the balloon 5 and the strip 1. A non-elastic reinforcing member 11 inserted on the opposite side of the balloon 5 can be varied, or the confronting portion of the strip 1 against the balloon 5 can be formed of a non-elastic reinforcing member stronger than the materials of other portions of the strip.

A filtering circuit with a jammer generator cancels a jammer in wireless signals with little degradation of the signal-to-noise ratio (SNR). The filtering circuit may include a jammer generator which acquires information of period and phase of a sinusoidal jammer signal in a composite input sinusoidal signal, which includes the jammer signal and a desired signal, and outputs a pseudo sine-wave with a period and phase corresponding with the period and phase of the jammer signal acquired, and an adder which outputs a difference between the input and output signals of the jammer generator as the desired signal.

A variable gain voltage/current converter circuit of the present invention has an input section active element having an input terminal, an output terminal, and a ground terminal for performing a voltage/current conversion, a potential control circuit for controlling a conversion gain of the input section active element based on a potential at the output terminal of the input section active element, an output section voltage/current converter circuit for generating a current corresponding to a voltage signal generated from the potential control circuit, and a current compensation circuit connected to the output terminal of the input section active element for generating a DC current in accordance with the amount of DC current which flows from the output terminal of the input section active element to the input section active element. The current compensation circuit compensates for a change in a DC current of the input section active element, which occurs when the conversion gain is adjusted. This minimizes fluctuations in operating points of other circuit elements.

In a diagnosis apparatus for an electronic control system adapted to vehicles and including a speed sensor for producing speed pulses responsive to the actual vehicle speed, a switch produces a diagnosis signal when actuated upon request for self-diagnosis in operation of the control system. A computer is responsive to the diagnosis signal to discriminate change of the level of each speed pulse during movement of the vehicle and to produce a first signal in dependence upon discrimination of change of the level of each speed pulse and a second signal in dependence upon discrimination of unchangeable state of the level of each speed pulse, and an indicator indicates an error in operation of the speed sensor in response to the second signal and normal operation of the speed sensor in response to the first signal.

An automatic control system for such a prime mover as a vehicle engine is adapted to automatically stop the prime mover when such a driven device as a vehicle is arrested, to automatically drive the prime mover in response to operation of a starting mechanism for effecting start of the driven device, and to maintain the prime mover in its operative condition when the driven device is moving. The control system is arranged to be inoperative in an expected occurrence of an error in operation of a setting switch for the system and to indicate the operative condition of the system under normal control of the setting switch.

A power amplifier amplifies a radio signal. Negative feedback is applied to a linear amplifier and the linear amplifier receives an envelope signal. A pulse current modulator is connected to a power supply terminal of a power amplifier and an output terminal of the linear amplifier via an inductor, and outputs a pulse current according to a control signal generated from the envelope signal. A diode has an anode connected to an output terminal of a direct current source and a cathode connected to an output terminal of the pulse current modulator. A switching element is disposed between the output terminal of the direct current source and a ground potential, and is controlled by the control signal.
