Patent CA-2014778-A1 (CA)
Inventor: EKMAN THURE
IPC: F16L37/38
Filed: 1990-04-18
Abstract: Coupling arrangement comprising connectable male and female parts (1, 2).  The male part can be partially inserted into the female part.  The female part comprises a longitudinally displaceable inner sleeve (4) which, in the non-actuated position of the female part, is caused to assume a closed position.  When the male part is inserted into the female part, the inner sleeve is acted upon counter to the action of a spring function towards an open position, in which the media passage through the coupling is open.  At its section (18) which can be inserted into the female part, the male part is provided with an inner surface (18a) which, upon insertion of the male part into the female part, surrounds a corresponding outer surface (4d) on the inner sleeve.  Sealing members (18b, 18c and 21) prevent media leakage during the coupling movement of the male and female parts.  The inner sleeve is designed so as to execute, upon exposure to a media pressure, for example a media pressure in the male part, a longitudinal displacement movement towards its fully open position dependent on the media pressure and independently of the male part.  The sealing members effect their sealing function during the whole of the independent longitudinal displacement movement.

Title: Negative feedback circuit to control the duty cycle of a logic system clock
Inventor: MILLER JOSEPH P
IPC: H03K5/156
Filed: 1990-05-14
Abstract: NEGATIVE FEEDBACK CIRCUIT TO CONTROL THE DUTY CYCLE OF A LOGIC SYSTEM CLOCK             ABSTRACT       A circuit for controlling the duty cycle of a high frequency logic system clock using negative feedback.  A high-level buffer used to drive the system clock bus receives the output of a crystal oscillator.  The buffer output is sampled by an integrator circuit which produces a voltage level corresponding to the duty cycle of the clock, and this voltage level is compared to a reference voltage using an operational amplifier.  The op-amp output is applied to the buffer input as negative feedback to alter the bias level at the buffer input in a way as to vary the point in the rising and falling transitions of the crystal oscillator where the threshold of the buffer is crossed.  A circuit monitors the clock signal output of a high-level buffer, and determines whether the duty cycle of the crystal oscillator which drives the output buffer should be increased or decreased.  A corresponding DC bias to the input of the output buffer causes the crystal oscillator output to reach threshold levels of the output buffer at different times during each clock pulse, thus adjusting the duty cycle of the buffer output. An RC integrator is used to monitor the buffer output, and the output of this integrator is compared with a reference voltage in an operational amplifier.  The output of the operational amplifier biases the input to the output buffer to a level corresponding to a need to increase or decrease the duty cycle of the buffer output clock signal.

Abstract: .lambda.          ABSTRACT OF THE DISCLOSURE         A waveform displaying device, in which a measured analogue signal is converted into a digital signal by means of an analogue to digital converter and thereafter the digital signal is directly inputted in a display device such as a raster scanning display, a liquid crystal display device, effecting the display while controlling the brightness of pixels so as to reproduce to display waveform of the measured analogue signal.  In the present device the brightness of pixels is varied, depending on slew rate of the waveform, so that the brightness of interpolation lines is increased, when differences between inputted waveform data are small, and the brightness is decreased, when the differ-ences are small.  Further places, where the density of waveforms is high, are displayed brightly by accumulating the brightness thereof.  In this way, since peculiar points in the waveforms such as points, at which the phase, the frequency or the amplitude is varied, are displayed as points, at which the brightness is varied, it is possible to find easily these points and further observation is easy, also in the case where a number of waveforms are displayed, superposed on each other.
