Abstract: An article that comprises novel means for modulating the transparency of a semiconductor body (20) in accordance with a modulating signal is disclosed. The body comprises one or more quantum wells (QWs, 23), and the modulation mechanism comprises changing the free carrier distribution function in the QWs. An important feature of the inventive article is the use of (relatively long wavelength) inter-subband radiation (ISBR, 28) to change the transparency of the body for (relatively short wavelength) inter-band radiation (IBR, 27). In preferred embodiments the modulating signal is an electric field applied across the QWs, such that ISBR absorption can be tuned by means of the Stark effect. One embodiment of the invention makes it possible to rapidly modulate IBR, and another embodiment can form narrow (typically less than 10 ps) IBR pulses.

Abstract: This data query apparatus consists of an application software and a circuitry for the processing of the data selection condition of the user query embodied in a host data base management system or information retrieval system. The application software translates the selection condition into the standard form which the circuitry can process. From the host system, and for each data record to be analyzed, the circuit apparatus receives the logical values taken on by the atomic conditions of the query and returns the logical value that the global selection condition takes on. This system allows the user to query the data on the basis of any truth-valued logic set up an arbitrary number of logical values, within the limits fixed by the system developer.

Abstract: In a method of producing a semiconductor device, when a device, for example, transistor, is formed in a prescribed region of compound semiconductor layers including a low resistance layer which cannot be insulated by ion implantation, upper layers of the compound semiconductor layers including at least the low resistance layer are formed into a mesa shape by etching, and then ion implantation is performed to the compound semiconductor layers in a region other than the region beneath the mesa structure. Thus, the device formed on the substrate is completely isolated from other regions on the substrate by the mesa-etching and the ion implantation. In the structure thus obtained, a level difference on the substrate due to the device is within a range that does not adversely affect the subsequent process steps, for example, a step of producing electrodes. In addition, materials and compositions of the compound semiconductor layers isolated by the mesa-etching are selected according to desired device characteristics without palying considerations on the insulation by ion implantation. Therefore, a degree of freedom in selecting materials and compositions of the compound semiconductor layers formed on the semiconductor substrate increases, resulting in a high-performance device.

Abstract: The video signal containing portions locally unsuitable for coding is divided into a plurality of components (Y,C R ,C B ) and is coded by a method such as a Wavelet transform and then is transmitted. In this case, a first quantizing means (32) controls a quantization characteristic per block consisting of small area segments of coefficients composed of respective components to make uniform a distortion within the picture and a visual obstacle caused by the distortion. A second quantizing means (34) controls the quantization characteristic to make uniform a deterioration quantity of the entire picture within a range of a predetermined coded data quantity. It is therefore possible to effect the transmission with a stable picture quality against a variety of fluctuations in the video signal inputted.

Abstract: The invention relates to a codable cylinder lock (1) having at least one blocking body (6) secured against rotation and having at least one cylinder body (12, 14) which is rotatable about an axis of rotation (10) relative to the blocking body (6) by means of a key (8, 8') matched to the particular coding of the cylinder lock (1), and having tumblers (16) which are displaceable in recesses (20) of the cylinder body (12, 14) and of the blocking body (6) and at least some of which pass, with the lock blocked, through at least one parting plane (76, 78) arranged between the blocking body (6) and the cylinder body (12, 14), the design of at least some of the tumblers (16) being reversibly variable. In order to provide a large number of coding possibilities and, at the same time, to prevent a new key being necessary each time after a recoding of the cylinder lock (1) or the number of coding possibilities from being restricted by the design of the key, it is proposed, according to the invention, to make the key (8, 8') likewise codable, specifically in such a way that it can be matched reversibly both to a changed number and to a changed arrangement of the tumblers passing through the parting planes. <IMAGE>

Abstract: . An electrostatic measurement apparatus having a single balanced beam vibratory element supported and balanced at its center, so that it may be driven in a manner to cause a regular vibration of the beam. The apparatus also has an electrode suitable for sensing a capacitive coupling relationship with an electrostatic field to produce a signal indicative of the magnitude of the electrostatic field. The coupling of the electrode with the electrostatic field is modulated (coupled/decoupled) either by attaching the electrode to the end of the beam and vibrating the electrode past an aperture, or by affixing a vane to the end of the beam, whereupon the vibration of the beam causes the vane to oc- dude the electrode from capacitively coupling with the electrostatic field.

Abstract: Superconductors using oxide superconducting materials having pinning centers inside crystal grains are enhanced in transmissible critical current density and allowed to have a high critical current density even in the magnetic field. A superconductor is produced comprising superconducting materials having a high irreversible magnetic field where the c axes of their crystals are oriented in one direction. This can be practically realized by heat-treating a superconducting material having a composition expressed by the Composition 5 together with Bi2Sr2CaCu2O8 having a tendency of growing in the form of plate crystal. Various apparatuses capable of working under cooling with liquid nitrogen let alone with liquid helium and having a high superconducting critical current density even in a high magnetic field can be produced.

Abstract: A communications system simultaneously transmits both a primary data signal and a secondary voice signal in such a way that the dynamic range of the secondary voice signal is increased even though deliberate errors are introduced into the transmitted data portion of the signal. In particular, the communications system includes an error correcting technique like channel encoding and the constellation signal space is divided into a number of regions, where at least one of the regions overlaps with another region. The primary signal is channel encoded to select a particular one of the number of regions, the region being represented by a reference signal point value. The voice signal is encoded to provide a signal point vector, which is added to the reference signal point in such a way that the resultant signal point is located in the overlapping region thereby deliberately introducing an error into the resulting transmitted signal point stream. Notwithstanding the deliberately introduced error, the channel encoding of the primary signal allows a receiver to recover the originally selected reference signal point value, which when subtracted from the received signal point value approximates the voice signal.
