Abstract: ABSTRACT OF THE DISCLOSURE       A portable light weight completely self-contained emergency single patient ventilator/resuscitating apparatus (10) usable at the scene of an emergency by persons with minimal training.  The appara-tus (10) includes a housing assembly (12) which supports a solid state oxygen generator which also acts as a power supply, the gen-erator being in the form of a chlorate candle (20).  The housing additionally supports a pump (90) in the form of a venturi ejector, a two-position valve (92), and suitable primary controls (93) which are utilized to control the inspiratory:expiratory (I:E) ratio, the inspiratory time, the expiratory time, the breaths per minute, the flow rate, the tidal volume, the minute volume, etc.  Various fluid passageways (54, 58, 116, 118) interconnect the candle with the valve, and additional fluid lines (120, 138, 140, 146, 148) inter-connect the valve with the pump and primary controls.  The primary controls include a fixed volume timing chamber (132) which is dis-posed about the venturi ejector.  The housing is provided with a void (98) adjacent the timing chamber, which void acts as an accumu-lator during the expiratory cycle.  While the two-position valve is normally automatically switched between inspiratory and expiratory positions by the primary control, it may be manually switched from its expiratory position to its inspiratory position against full pilot line pressure by a secondary control including a push button (152) or the like when the operator desire to give extra breaths or sigh breaths.  In addition, the push button can be so positioned that the valve may be maintained in its inspiratory position, which may be desirable when the patient is breathing on his own and only requires extra oxygen over that which he would normally receive from ambient air.

IPC: B29C45/16
Filed: 1990-06-28
Abstract: The present invention relates to a mold for producing a multilayer molded article which article is comprised of a resin body and a skin material on a surface of the resin body. The mold consists of male and female molds, wherein the shortest horizontal distance of a mating gap between the horizontally outermost wall surface of the male mold to which the skin material contacts and the horizontally innermost wall surface of the female mold to which the skin material contacts is 0.25 to 3 times the minimum thickness from which the once compressed skin material can restore to the original thickness. In addition the shortest length L in a mold closing direction of a mated part formed between the outermost wall of the male mold to which the resin melt contacts and the innermost wall of a flange of the female mold satisfies the equation: (t1 - t0 + 10) mm ~ L ~ (t1 - t0) mm.      In this equation t1 is a distance (mm) between the male and female molds when the resin melt first reaches the horizontally outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1 when the mold closing is completed.

Abstract: An impulse sequence of a pitch frequency is detected from a phase-equalized prediction residual of an input speech signal, and a quasi-periodic impulse sequence is obtained by processing the impulse sequence so that a fluctuation in its pitch frequency is within an allowed limit range.  The magnitudes of the quasi-periodic impulse sequence are so determined as to minimize an error between the waveform of a synthesized speech obtainable by exciting an all-pole filter with the quasi-periodic impulse sequence and the waveform of a phase-equalized speech obtainable by applying the input speech signal to a phase equalizing filter.  Preferably, the quasi-periodic impulse sequence is supplied to the all-pole filter after being applied to a zero filter in which it is given features of the prediction residual of the speech.  Coefficients of the zero filter are also determined so that the error of the waveforms of the synthesized speech and the phase-equalized speech is minimum.
