Patent DE-68915035-T2 (DE)
Inventor: PLUMMER JAMES D
IPC: H01L29/10

Granted: 1994-08-25
Abstract: A bipolar transistor has a base region including a heterostructure and a doped layer (18) of semiconductor material with the heterostructure functioning as a two-dimensional hole gap. The doped layer (18) is sufficiently thin to prevent occurrrence of a charge-neutral region of holes. In operation the transistor can switch quickly since minority charge storage in the base region does not present a problem. The structure lends itself to down-scaling in size in a VLSI circuit.

Abstract: In the particular embodiments of the invention described in the specification, a projection transparency includes a transparent substrate and an ink pattern disposed on one surface of the transparent sheet in the form of three-dimensional ink spots having curved surfaces with a radius of curvature of at least 3 mils and an angle of contact with the substrate of no more than about 25 DEG . The transparency is prepared by applying ink drops to the substrate and maintaining the ink at a temperature above its melting point for a selected time such as 0.5 to 10 seconds. Thereafter, the ink is cooled rapidly to reduce crystallization and frosting and thereby reduce light transmission losses in the ink to less than 50%.

Abstract: A threshold detection logic circuit of simple and economical design is disclosed that indicates when the difference in the number of first operations to be counted and the number of second operations to be counted is either greater than or equal to a threshold value, or less than or equal to a threshold value. The threshold detection logic circuit employs the use of an overflow bit of a counter, which has a counting range of 2<N+1> for a threshold range of 2<N>, in order to generate a threshold interrupt signal. In addition, the disclosed threshold detection logic circuit permits the threshold value to be programmed to any desired value.

Abstract: The synthesizer is based on a phase lock loop structure comprising a reference signal generator (1), a first phase detector (2), a low pass filter (3), a VCO (4) and a frequency divider (5). In order to achieve a faster channel switching, maintaining the design of the filters as simple as possible, it is included a second phase detector (6) that receives the reference signal (9) and a second output signal (11) coming from the frequency divider (5) and shifted 90 DEG  with respect to its other output signal (10), and that generates a second phase error signal (13), in quadrature with the first phase error signal (12), that is filtered by a second low pass filter (7) generating a second filtered phase error signal (15).   The two filtered phase error signals (14,15) are taken to a quadratic correlator (8) whose output is supplied to the VCO (4) and its amplitude is proportional to the difference of the frequencies of the reference signal (9) and any of the output signals (10,11) from the frequency divider (5). <IMAGE>

Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue surrounds the tool and has a hollow elongate semi rigid central body about an axis with a funnel, at one end thereof and a nozzle, at the other to direct annular irrigant/coolant flow therethrough. The funnel and nozzle are resilient. Reinforcing ridges, inside the nozzle, act to maintain concentricity between the flue and nozzle tip and channel irrigant thereabout.

Abstract: Methods and apparatus for encoding and decoding information in broadcast or recorded segments signals are described. In certain embodiments, an audience monitoring system encodes identification information x(w) in the audio signal portion of a broadcast or recorded segment using spread spectrum encoding (100). A personal monitoring device (200) receives an acoustically reproduced version of the broadcast or recorded signal via a microphone (230), decodes the identification information from the audio signal portion despite significant ambient noise and stores (260) this information, automatically providing a diary for the audience member which is later uploaded to a centralized facility. A separate monitoring device (700) decodes additional information from the broadcast signal, which is matched with the audience diary information at the central facility. This monitor (700) may simultaneously send data to the centralized facility using a dial-up telephone line, and receive data from the centralized facility through a signal encoded using a spread spectrum technique and modulated with a broadcast signal from a third-party.

Upon practical use, the outer water-insoluble film 2 is peeled off to expose the internal film 3 and the internal film 3 as such, while containing the agricultural chemical agent 6, is introduced into water. Thus, the internal film is dissolved in water and in turn the content 6 thereof is released and accordingly dissolved in water.
