Patent EP-0387793-A2 (EP)
Inventor: WALDMANN JUERGEN PROF DR SC TE
IPC: A61B5/026
Filed: 1990-03-13
Abstract: The invention relates to a process and a means for representing structures (ST) which are predominantly biological, or have been technically produced. The process enables the representation of inhomogeneous structures (ST) in situ in real-time operation. It can be used to produce IR and NIR tomograms, and to determine the volumetric flow in capillaries and filters, and can be employed in medicine, biology and technology in order to observe and assess structures (ST), surfaces, volumes and volumetric flows in which chemical and physical processes take place. According to the invention, the IR light sources and receivers that are arranged in a one plane are guided as large-area radiators and receivers (SE) with respect to the object in the x-y-z direction, the large-area radiator radiating with a specific radiation cross-section and a specific intensity, the emitting IR diodes being driven with a peak current of preferably up to 1A at a pulse frequency of preferably up to 100 kHz, and the backscattering being detected. Together with the arrangement of the sensor (SE) for the large-area radiator/receiver, profiles, determined in real time, of the IR attenuation gradients of the volumetric elements permit an exact spatial assignment of the volumetric elements in the micrometre to centimetre range and a contrast representation of specific structures (ST). <IMAGE>

Abstract: An anti-icing system for leading edges (12) of an aircraft. Hot compressed air is discharged from a cavity behind the leading edge (12) through a multitude of small holes in the leading edge skin (30) into the airflow impinging on the leading edge. In a first embodiment the anti-icing system utilizes part of the air distribution system in existence for a laminar flow control system. Instead of sucking air into the wing, as is done in the laminar flow control mode, the flow is reversed in the anti-icing mode, blowing hot compressed air out of the wing. In a second embodiment the anti-icing system is used solely in the anti-icing mode.

Abstract: In a pipelined computer system, memory access functions are simultaneously generated from a plurality of different locations. These multiple requests are passed through a multiplexer 50 according to a prioritization scheme based upon the operational proximity of the request to the instruction currently being executed. In this manner, the complex task of converting virtual-to-physical addresses is accomplished for all memory access requests by a single translation buffer 30. The physical addresses resulting from the translation buffer 30 are passed to a cache 28 of the main memory 14 through a second multiplexer 40 according to a second prioritization scheme based upon the operational proximity of the request to the instruction currently being executed. The first and second prioritization schemes differ in that the memory is capable of handling other requests while a higher priority "miss" is pending. Thus, the prioritization scheme temporarily suspends the higher priority request while the desired data is being retrieved from main memory 14, but continues to operate on a lower priority request so that the overall operation will be enhanced if the lower priority request hits in the cache 28.

Abstract: A method of fabricating a thermal ink jet printhead of the type produced by the mating of an anisotropically etched silicon substrate containing ink flow directing recesses with a substrate having heating elements and addressing electrodes is disclosed. An etch-resistant material (19) on one surface of a (100) silicon substrate is patterned to form at least two sets of vias therein having predetermined sizes, shapes, and spacing therebetween. The predetermined spacing permits selected complete undercutting by an anisotropic etchant within a predetermined etch period. The patterned silicon substrate is anisotropically etched for the predetermined period to form at least two sets of separate recesses (15), each recess being separated from each other by a wall (17), the surfaces of the walls (17) being {111} crystal planes of the silicon substrate, whereby certain predetermined separately etched recesses are selectively placed into communication with each other by the selective undercutting while the remainder of the undercut walls provide strengthening reinforcement to the printhead, so that larger printheads may be fabricated which are more robust without relinquishing resolution or reducing tolerances.

Abstract: In semiconductor memory device having a plurality of memory cell arrays in which a potential difference between a pair of bit lines to which memory cells are connected is amplified by a sense amplifier operating responsive to a sense latch signal on a common node, and the memory cells are connected via a power supply line to a power supply, the adverse effects due to the resistance of the power supply line is eliminated or reduced. This is achieved by coupling a power supply auxiliary line disposed within each memory cell array and a power supply main line disposed along the memory cell arrays by means of a resistive element having a resistance larger than the resistance of the power supply main line from the power supply to the memory cell array located farthest. Alternatively, the common node in each memory cell array is connected to said power supply main line via a resistive element and a sense amplifier drive transistor which is turned on and off by a control signal. Still alternatively, the transistors which are turned on by a control signal to connect the sense amplifiers to a power supply main line have a different mutual conductance depending on the resistance of the power supply line.

Abstract: Disclosed herein is a charged particle beam apparatus which comprise the components below operating as follows: 
A charged particle beam generating system causes a charged particle source (1) to generate a charged particle beam (2). A charged particle beam focusing system focuses the charged particle beam onto a sample (8). A charged particle beam deflecting system (9) causes the focused charged particle beam to scan the surface of the sample. An evacuating system evacuates a space through which the charged particle beam passes. A detector (15) detects information obtained by irradiating the charged particle beam onto the sample. An image display system (16) displays as an image the status of distribution of the information over the sample surface based on a detection signal forwarded from the detector. The charged particle beam focusing system is entirely constituted by an electrostatic lens containing a plurality of lens electrodes, one of the lens electrodes being a final electrode (7) located closest to the sample. All of the lens electrodes except for the final electrode are supplied with positive voltages as opposed to a negative voltage to the final electrode when the charged particle beam is negatively charged (e.g., electron beam). All of the lens electrodes except for the final electrode are supplied with negative voltages as opposed to a positive voltage to the final electrode when the charged electron beam is positively charged (e.g., positive ion beam). The charged particle beam deflecting system is so constructed as to deflect the charged particle beam within the inner space of the plurality of lens electrodes excluding the final electrode.

Abstract: At a transmitting end, transmission signals corresponding to more than one channel are allocated different microwave frequencies and carriers of the microwave frequencies are modulated with the transmission signals in modulators. A filter (32-1 to 32-k) is placed in the preceding or succeeding stage of a respective modulator (31-1 to 31-k) to band-limit a corresponding transmission signal before or after modulation. The band-limited and modulated transmission signals are combined to produce a microwave frequency-division multiplexed signal. The multiplexed signal modulates an optical frequency modulator (33) to produce an optical modulated signal. The optical modulated signal is transmitted to the receiving end. At the receiving end, the optical signal transmitted from the transmitting end is detected and converted to an electrical signal. The channel components are extracted from the electrical signal by bandpass filters (36-1 to 36-k) and then demodulated.

In addition, the temperature-dependence of the frequency of oscillation of the first crystal vibrator (9) is matched to that of the string vibrator (1). These measures provide in a simpler and less expensive manner than previously information on the absolute temperature which is available for compensation purposes, and also an improvement with regard to the temperature compensation of the string vibrator (1).
