Patent EP-4276227-A3 (EP)
Inventor: YAMAGATA NORIO
IPC: C30B19/04
Filed: 2022-09-07
Abstract: A SiC single crystal is produced by impregnating a molten alloy of silicon and a metallic element M that increases carbon solubility into a SiC sintered body to form a SiC crucible, placing silicon and M in the crucible and heating the crucible to melt the silicon and M and form a Si-C solution, dissolving silicon and carbon in the solution from surfaces of the crucible in contact with the solution, contacting a SiC seed crystal with the top of the solution to grow a first SiC single crystal on the SiC seed crystal by a solution process, and bulk growing a second SiC single crystal on a face of the solution-grown first SiC single crystal by a sublimation or gas process. This method enables a low-dislocation, high-quality SiC single crystal to be produced by a vapor phase process.

     Zur optimalen Nutzung der am Absorber und Kondensa­
tor bzw. Resorber verfügbaren Wärme wird erfindungsge­
mäß das Heizmedium wechselweise im Wärmeaustausch mit 
Teilen des Absorbers und Kondensators bzw. Resorbers 
geführt. Das zu erwärmende Heizmedium tritt in jedem Fall 
zunächst in Wärmeaustausch mit einer Kondensator- bzw. 
Resorberzone und durchströmt danach mindestens je eine 
Absorber- und Kondensator- bzw. Resorberzone. Abhängig 
vom Stoffpaar sowie den Betriebsbedingungen ist die letzte 
Tauscherzone entweder eine Kondensator- oder eine Absor­

der vom Heizmedium durchströmten Bereiche der Wärme­
tauscher, die vorzugsweise aus konzentrischen Rohrschlan­
gen bestehen, beträgt deshalb mindestens drei, vorzugs­
weise fünf oder sieben, wenn eine Kondensatorzone, minde­
stens vier, wenn eine Absorberzone und mindestens fünf,

Abstract: An air flow rate measuring device for use with an 
internal combustion engine in which a signal accurately 
representing the air flow rate of intake air in an intake 
air passage (1) of the engine is always available. A first

Title: Control device for selectively converting a continuous rotary motion into a singular oscillating motion of a control lever with respect to the angle of rotation
IPC: B41F13/00
Filed: 1983-10-26
Abstract: The invention relates to a mechanism for selectively converting a continuous rotary movement in apparatus such as a high-speed-printing machine to a phase-related single pivoting movement of a control lever, with that single control movement following by an immediate reset to the initial position regardless of the time of activation of the mechanism. An entrainment lever supported on a supporting pin is coupled by means such as an excentric drive to the continuous rotary movement of the machine to generate a continuous pitching movement. A control lever is mounted for rotation on the same support pin and mounts a bistable mechanism (tensioning lever, pawl 3, tensioning spring 21) which in its first stable condition allows the entrainment lever to oscillate freely and which can assume its second stable condition when entrainment lever is in a dead center position, causing an engagement surface to be offered to the entrainment lever with the range of its pivoting movement. Control lever is spring-biased towards entrainment lever by return spring, and the control movement of control lever causes said bistable mechanism to be reset to its first stable condition by means of a reset lever.

Title: Method and apparatus for controlling diesel engine exhaust gas recirculation partly as a function of exhaust particulate level
IPC: F02D21/08
Filed: 1983-10-03
Abstract: A method and apparatus for controlling the recirculation of exhaust gas in a diesel engine includes an EGR valve responsive to an EGR control signal for relatively opening and closing a recirculation duct to the passage of exhaust gas therethrough. A sensor provides a signal indicative of the level of particulates in the exhaust gas stream. Control circuitry responsive to various signals indicative of engine operating conditions, including the signal indicative of exhaust gas particulate level, provides an EGR control signal for regulating the EGR valve at least partly as a function of the sensed level of particulates in the exhaust gas stream. The engine operating condition signals typically are indicative of the speed of the engine or fuel injection pump, the engine load, and engine operating temperature. The particulate level signal is preferably provided by electrostatically sensing the passage of packets of charged particles by an electrically-passive, annular electrode positioned in or adjacent to the exhaust gas stream. The control circuitry includes storage of open loop EGR valve control signals as a function of speed and load, as well as particulate objective signals also as a function of speed and load. The sensed exhaust gas particulate level is compared with the appropriate particulate objective signal for the development of an error signal, which error signal is then used in an adaptive manner to adjust the open loop EGR control signal in a direction to diminish the particulate error signal. Such adaptive control of the EGR control signal as a function of the exhaust gas particulate level is further advantageous because a predeterminable relationship exists between exhaust particulate levels and NOx levels as a function of percent EGR. EGR control may be inhibited by depressed engine temperature.

Patent EP-0124016-A3 (EP)
IPC: G01R33/563
Filed: 1984-04-17
Abstract: A method and apparatus for producing two-dimensional, 
plan view images of in vivo blood flow networks using unique 
nuclear magnetic resonance (NMR) pulse sequences are dis­
closed. The method teaches the use of a pair of 90° selective 
pulses separated by a delay time optimized to provide images 
with enhanced blood flow contrast by discriminating against 
stationary media surrounding the blood flow path. For the in­
stant method, two-dimensional images are compiled by the il­
lustrative apparatus using a collection of NMR slice data, 
wherein each slice reflects a one-dimensional projection of 
NMR received signal data in a thin planar slab selected to be 
generally orthogonal to the primary blood flow network. Fur­
ther alternative embodiments discuss the use of free induction 
decay (FID) signals, as well as single pulse and multiple pulse 
spin echo sequences.
