Abstract: A combustible gas sensor having a pair of
temperature sensor sections is here disclosed. One of the
pair of temperature sensor sections is covered with porous
oxidizing catalytic layers (23, 24) for oxidizing a
combustible gas, and the other is not covered with the
oxidizing catalyst layers. In the one temperature sensor
section, the combustible gas is burned, and in the other
temperature sensor section, the temperature of a gas to be
measured is compensated. The temperature sensor sections
each comprises temperature sensitive portions (13, 14)
made of a dense ceramic material, resistors (21, 22)
buried therein and having a positive resistance
temperature coefficient, current leads (31, 32, 41, 42)
and voltage leads (33, 34, 43, 44). A method for
measuring the concentration of the combustible gas by the
use of this combustible gas sensor is also disclosed. A
method for detecting the deterioration of a catalyst which
intends to eliminate the combustible gas, by the use of
this combustible gas sensor is further disclosed. When a
difference between temperatures of the pair of resistors
or a difference between powers fed to the pair of
resistors is in excess of a predetermined value, it is
judged that the catalyst has been deteriorated. The
combustible gas sensor of the invention is excellent in 
durability at a high temperature, and it can measure the
gas to be measured whose temperature largely changes.

Abstract: An improved method and circuit for a word line driver in
memory integrated circuits is disclosed. Instead of connecting the gate
terminal of an isolation transistor to a constant high power supply voltage,
the present invention momentarily boosts the voltage at the gate terminal to
allow for a full logic high voltage to be transferred to the gate terminal of a
word line driver transistor. Then the voltage at the gate terminal of the
isolation transistor is reduced to its original level before the signal at the
drain terminal of the word line driver transistor is boosted from ground to
voltages above the power supply level. Thus, a maximized boosted voltage
is trapped at the gate terminal of the word line driver transistor to improve
the drive capability of the word line driver transistor.

Abstract: An ophthalmic pachymeter which is highly effective in aiding 
in the determination of thickness and the optical density of the 
cornea of an eye on a real-time basis. The pachymeter therefore 
lends itself to effective employment in aiding in radial keratotomy 
and other surgical procedures with respect to the eye. The 
ophthalmic pachymeter of the invention has three major subsystems 
which include a television camera, a multiple slit projector and an 
associated processing and display system. In a broad form, the 
invention comprises illuminating a selected portion of the cornea, 
moving a slit across the cornea and generating Tyndall image ray 
paths for enabling analysis of the optical density of the cornea 
and the thickness of the cornea. This is accomplished through a 
series of digitally-encoded television images of the optical 
section of the cornea produced by a multiple slit projector and 
which images are then subjected to digital analysis. A locus of 
each of the significant elements of the reflected image of the 
anterior portion of the eye is defined. In this way, the optical 
character of the cornea/air interface is compared with the 
corrected reflectance of the stroma and the endothelium, in order 
to determine relative transparency. In accordance with the present 
invention, it is possible to determine physical contour parameters 
of a portion of the cornea of the eye by using a pair of slits so 
that distance measurement between portions of the eye can be 
obtained.

Abstract: An algorithm is disclosed that enables the display for a medical ventilator (10)
to automatically adjust its wave characteristics depending on the settings for
that ventilator (10) established by the clinician. As the respiratory rate, or rate at
which the ventilator (10) provides breaths to the patient (12), is changed by the user,
the rate of sweep (30) of the waveform generator displaying that data is also
changed to ensure that the data is displayed in the most relevant manner. As
another parameter, as the pressure limit (18) in the patient circuit (14) is set
by the clinician, the waveform vertical scale (34) is adjusted to make sure the particular
limit of pressure is displayed. As the pressure limit (18) or the respiratory rate (16) are
changed in the ventilator (10) by the clinician, the waveform of the data displayed
also is automatically modified to make that data best presentable to the
clinician.
