Inventor: NAKATANI HAJIME MITSUBISHI DEN
IPC: H01S3/225
Filed: 1988-09-22
Abstract: In a laser device a laser beam is produced by a variable-wavelength laser generator which has a Fabry-Perot etalon to select a laser oscillation wavelength, and the laser beam is monitored by a wavelength monitor means whose output sig­nal is used to adjust a gap pressure of the Fabry-Perot etalon. In order to adjust the gap pressure, the Fabry-Perot etalon is contained in a gas-filled container, and the gas pressure is adjusted by the output signals to tune and stabilize the wave­length.   
     ABSTRACT 
     A laser apparatus comprising a Fabry-Perot etalon for selecting a laser oscillation wavelength and a wavelength monitor means for monitoring a laser beam taken out from a laser oscillator whose wavelength is variable, whereby the pressure at the gap in the Fabry-Perot etalon is adjusted on the basis of a signal output from the wavelength monitor means. In order to adjust the pressure at the gap the Fabry-Perot etalon is hermetically sealed in a vessel containing a gas and the gas pressure is controlled on the basis of the output signal.

Patent EP-0394534-A1 (EP)
Inventor: FRANKEN WILHELM DIPL-ING
IPC: B64F1/10
Filed: 1989-04-28
Abstract: The subject matter of the invention is an aircraft tractor without a towing bar. 
<??>The prior art is a tractor according to DE 3,616,807 A1, whose lifting blade, which is provided to accommodate the aircraft nose undercarriage, is rigidly connected to the front part of the running gear. Consequently, telescopic rods, provided with rear nosewheel tension arms, and front nosewheel holders are arranged fixed on the front part. 
<??>The disadvantage of these attachments are the relative movements with respect to the lifting blades, the tension arms and the holders which occur when the tractor of an aircraft drives along a curve with the nose undercarriage obliquely forwards. 
<??>It is therefore the object of the invention completely or largely to avoid these relative movements. 
<??>This object is achieved when the lifting blades (24) can be rotated about a horizontal longitudinal axis (30) of the running gear (10) when the latter is extended, and the transversely located tension arms (38) and/or the holders (42) can move with respect to said longitudinal axis (30). 
<??>The advantage of this solution is the general production of the tyres of an oblique nose undercarriage of an aircraft being towed in a curve, because tractor parts (24, 38, 42) applied to the nose undercarriage follow the movements thereof and can adapt themselves to its momentary position.

Abstract: The frequency modulator utilizing a frequency synthesizer comprises a voltage controlled oscillator (VCO-2), a programable frequency divider (4), a reference oscillator (8), a phase comparator and a phase locked loop. The VCO (2) comprises a first variable capacitor (24) receiving the control voltage from the phase comparator (6) and a second variable capacitor (26) receiving an input modulation signal. A bias circuit controls a bias to be supplied to the second variable capacitor (26) in accordance with the control voltage delivered from the phase comparator (6). An undesirable change of the modulation sensitivity due to difference of the oscillation frequency is compensated by controlling the reverse bias to be applied to the second variable capacitor (26) receiving the input modulation signal depending on the frequency control voltage for the VCO (2).

Inventor: CETINKAYA ISMAIL BIRKAN
IPC: B01F23/00
Filed: 1989-05-22
Abstract: A liquid feed injector for use in contacting a stream of fluidized particles with a finely dispersed liquid uses a gaseous stream and sequential mixing stages of increased severity to fully atomize the liquid portion of the combined liquid and gaseous stream. Sequential mixing consists of a first mild mixing that takes place in a mild mixing zone and blends the liquid and gaseous material into a substantial uniform mixture. The uniform mixture of liquid and gaseous material passes through another stage of vigorous mixing where the liquid is sheared and gas is dispersed throughout the liquid to produce a homogeneous mixture of fine gas bubbles dispersed in the liquid. The homogeneous liquid and gas mixtures are then discharged through one or more discharge nozzles to effect atomization and distribution of the liquid in a suspension of fluidized solids. The sequential stages of increased severity mixing allow atomization of the liquid into fine droplets with a reduced pressure drop across the discharge nozzles. In a highly preferred form, the liquid injector includes provisions for injecting two fluid streams into a suspension of fluidized solids at two discrete locations.

Abstract: Pulses of an ultrasonic wave beam are emitted (1) into a body at a predetermined repetition period. Echo pulses of the ultrasonic wave beam are received (1) via a plurality of different channels. Each of the received pulses is converted (2) into corresponding electric signals of the respective channels. A pair of adders (59, 60) invert signs of alternate ones of pairs of the electric signals of adjacent channels, summing the inverted sign electric signals with remaining non-inverted sign electric signals, converting the electric signals into a pair of complex signals having phases which are spatially different from each other by 90 degrees. An autocorrelation function (65) of the complex signals is calculated. A component of a speed of moving matter within the body in a predetermined direction is calculated on the basis of the autocorrelation function. The moving matter causes the echo pulses. The predetermined direction is perpendicular to a direction of travel of the ultrasonic wave beam pulses.
