Title: Vibration-type rheometer apparatus
Inventor: SUZUKI OSAMU
IPC: G01N11/16
Filed: 1988-11-17
Granted: 1993-03-30
Abstract: ABSTRACT     A vibration-type rheometer comprises a vibration-type viscometer having a pair of vibrator subassemblies which resonate as in a tuning fork.  The pair of vibrator subassemblies constituting a tuning fork vibrator each has at its free end a sensor plate formed from a thin metal plate places into a sample to be measured, and the vibrator subassemblies are driven at the same frequency but in opposite phase relationship to each other by an electromagnetic driving unit together with the sensor plates.  A control unit supplies a time-varying driving current whose magnitude varies with time to the electromagnetic driving unit in order to change the vibration-applying force applied to the pair of vibrator subassemblies.  The amplitude of vibration of the vibrator subassemblies changes as a function of the viscous resistance encountered by the sensor plates from the sample and the amplitude is electrically detected, and the detected value is sent to a recording unit together with the value of the driving current to thereby indicate the behavior of the sample.

Granted: 1991-11-26
Abstract: Abstract A high voltage generator of a television receiver includes a high voltage transformer having primary and high voltage windings. The high voltage winding is coupled to an ultor terminal of a picture tube via a high voltage rectifier. Retrace pulses applied to the primary winding are stepped up by the high voltage winding for generating an ultor voltage. A source of supply voltage is coupled to a current resupply terminal of the high voltage winding and produces voltage pulses at the resupply terminal having amplitudes which vary in accordance with ultor voltage loading.  An envelope detector is coupled to the resupply terminal for envelope detecting amplitude variations of the voltage pulses to develop a size control signal which follows loading induced variations in ultor voltage.  The size control signal is coupled to a scanning current modulator, such as a diode modulator, for modulating the scanning current in a manner that regulates the raster size.

A beam of light from a LED passes obliquely through the plastic tube and onto a photo-transistor.  When liquid is encountered in the well, the liquid enters the tube: the change in refractive index now directs the beam away from the photo-transistor.  The optical and conductivity sensors are both actuated at the same depth.

Abstract: A purified thermostable enzyme is obtained that has unique characteristics.   Preferably the enzyme is isolated from the Thermus aquaticus species and has a molecular weight of about 86,000-90,000 daltons.  The thermostable enzyme may be native or recombinant and may be used in a temperature-cycling chain reaction wherein at least one nucleic  acid  sequence  is  amplified  in  quantity  from  an  existing sequence   with   the   aid   of   selected   primers   and   nucleotide triphosphates.   The amplification process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide  primers,  extending the  primers with  a thermostable enzyme to form complementary primer extension products which act as templates  for  synthesizing the  desired nucleic  acid sequence,  and detecting the sequence so amplified.  The steps of the reaction can be repeated as often as desired and involve temperature cycling to effect hybridization, promotion of activity of the enzyme, and denaturation of the hybrids formed.  The enzyme is preferably stored in a buffer of non-ionic detergents that lends stability to the enzyme.

Abstract: Combustible impurities in oxygen-containing offgases are burnt according to a method and by an apparatus of the type in which at least some of the heat of combustion is recovered by a regenerative heat exchange in two identical heat exchange zones (10,11) containing a solid heat exchange material and separated by a combustion chamber (15). The air or gas to be purified flows through both of the heat exchange zones and by means of valves (1,2,3,4) the direction of flow is changed periodically so that the two zones are alternately heated and cooled in periods of 0.1-60 minutes. The risk of discharge of unburnt combustible contaminants to the atmosphere is minimized by dividing the purified gas stream in the first 1-50% of each period into two part streams of which one is discharged directly from the combution chamber (15) to a recipient (22) whereas the other is passed through the heat exchange zone (10 or 11) being heated and from there recycled through a line (25 or 24) controlled by a valve (7 or 6) and combined with unpurified gas being passed to the heat exchange zone (11 or 10) being cooled.

Abstract: A television ghost signal cancellation system is provided which compensates for the phase of the ghost carrier signal. A video signal containing a ghost signal component is applied to a variable delay line, which delays the video signal by an amount of time equal to the difference in time between the appearance of the direct video signal and its corresponding ghost signal components. The delayed video signal is modulated by a carrier signal and demodulated by a phase-shifted version of the carrier signal. The carrier signal is phase-shifted for the demodulator by an amount which compensates for the phase difference between the picture carriers of the direct and ghost signals. The demodulated signal is inverted and its amplitude adjusted to produce a pseudo-ghost signal which is substantially equal in amplitude but opposite in polarity to the ghost signal components. The pseudo-ghost signal is summed with the original video signal to cancel the ghost signal components, thereby producing a deghosted video signal.
