Abstract: The device is for suppressing snoring and apnoea during sleep. It is placed in the oro-pharynx and at the buccal cavity region during sleep. It comprises a flexible tube (1) arciform and transversally flattened, of adapted anatomical design, for being placed between the tongue (13) and the soft palate (15), down to at least the base of the tongue (14). A filter (2) is fixed to the external end of this tube. The filter can be removable. Thus, the air breathed in (10) moves freely from outside up to the larynx, without snoring or apnoea. A fixing system (24) is provided so that the tube is maintained well inside the mouth during sleep.

Abstract: A delay lock loop circuit is disclosed which includes a delay block which receives the clock signal and delays the clock signal by a selected amount to generate the delayed clock signal. A phase detector receives the clock signal and the delayed clock signal, compares the phases of the two signals and generates a phase comparison signal. A lock detector receives the clock signal and the delayed clock signal, compares the timing of the two signals and generates a potential lock indication signal. A controller receives the phase comparison signal and the potential lock indication signal and provides a delay control signal to the delay block to change the selected delay amount in response to the phase comparison signal. The controller interrupts the clock signal to the delay block for a selected interval in response to the potential lock indication signal, and generates a true lock indication signal in response to the potential lock indication signal after the interruption of the clock signal to the delay block.

Abstract: A charge transfer amplifier includes a first stage charge transfer amplifier coupled to a positive capacitive feedback mechanism. The positive capacitive feedback mechanism is attached to the output terminal of a first stage charge transfer amplifier. This reduces the capacitance viewed at the output terminal of the first stage charge transfer capacitor thus increasing the overall gain of the charge transfer amplifier. The positive capacitive feedback mechanism includes a second stage amplifier having an output terminal capacitively coupled back to the output terminal of the first stage charge transfer amplifier. The coupling of the positive capacitive feedback mechanism to the charge transfer amplifier allows for enhanced amplifier gain while still retaining the beneficial characteristics of charge transfer amplifiers generally.

Abstract: A current reference circuit provides a reference current that has a controlled temperature coefficient and is relatively stable with supply voltage fluctuations. The reference leg includes a series of MOS transistors including at least one PMOS transistor that is electrically closer in the series to a high voltage source, at least one NMOS transistor that is electrically closer in the series to the low voltage source.

Abstract: While a bag (1) made of a thin, soft, and less elastic material is packed with air and is positioned between contacts of soft materials, a thin tube (2) from the bag (1) is lead to the outside of the contacts, and the pressure difference with respect to atmosphere is measured, whereby the contact pressure of an elastic body can be measured. As water depth (A) (mmH.sub.2 O) is measured while the bag (1) is horizontally sank into the water, and as water temperature is changed while the water temperature is measured, the measured level can be calibrated together with thermal influence.

Abstract: A method and apparatus for forming draw tape bags wherein the bag material moves continuously during the manufacture, except for the last step. The apparatus may be used with an in-line system wherein a tube is extruded and a side gusset is formed to create a hem; or the apparatus may be used with an off-line system wherein folded bag material is used, and a continuous hemmer is provided to turn the loose edges. In the off-line system a constant tension dancer precedes the hemmer to maintain constant tension on the web regardless of the size of the supply roll. The web continues to move, and a cutter is actuated to move through a circle and engage the web to punch finger holes in the hem. A reel of a strip of material is continuously fed, the strip being slit longitudinally to provide the draw tapes which are inserted into the hems. A tape guide tensions the tape and assures that the tape is well within the hem, the hems are sealed, and the bags are side welded.
