Patent CA-1318418-C (CA)
Title: Heterostructure bipolar transistor
Inventor: CHEN YOUNG-KAI
IPC: H01L21/331
Filed: 1989-08-08
Granted: 1993-05-25
Abstract: HETEROSTRUCTURE BIPOLAR TRANSISTOR Abstract Improved heterojunction bipolar transistors (HBT) are disclosed. Inventive devices can attain high cut-off frequency (fT), exemplarily 80 GHz or higher, and high DC current gain (.beta.), exemplarily 25 or higher. The devices exhibit lateral scaling, permitting reduction in emitter stripe width without unacceptable decrease in .beta.. Exemplarily the stripe width is 1 µm or less. The inventive HBTs are hot electron devices, with the hot electrons in the base region being spatially confined such that relatively few electrons reach the surface of the extrinsic base region. The relatively low bulk and surface recombination rate in the base of inventive HBTs is an important aspect of the invention and makes possible devices having relatively high .beta. and low power consumption. Appropriate choice of base material, namely, a semiconductor material having relatively low intrinsic surface recombination velocity, can result in further reduction of surface recombination, as can, for instance, the use of an appropriate non-alloyed metal base contact. Appropriate choice of collector material can result in improved ballistic transport through the collector depletion region, and novel selection criteria are disclosed. InP, InAs, and In0.53Ga0.47As are exemplary materials that meet these criteria. Use of a highly doped collector contact region, with dopant level within a relatively narrow concentration range, can also lead to improved device behavior, as can the use of a compound emitter that comprises one or more appropriately placed thin undoped heteroepitaxial layers.

Abstract: An apparatus communicating with data systems, and a method of communicating with data systems. In an apparatus (10, 49) communicating with a high secrecy and high security on-line verification data system (40) and an off-line verification data system (18) of a lower secrecy and security level, a person in possession of a card (21, 22, 12, 24) inputs the card into the apparatus (10, 49). The data are read from the card and input to a security module (50) of the apparatus. On the basis of the data read from the card, the apparatus (10, 49) identifies the card as a card belonging to the on-line data system or the off-line data system. Within the security module (50) of the apparatus (10, 49), a keyboard (46) is arranged, which is adapted to be activated by the person in possession of the card for inputting a personal authentication code (actually a PIN-code) into the security module. Provided the card has been identified as a card belonging to the on-line data system (40), the data read from the card (21) and the code input by means of the keyboard (46) are encrypted by employed an encryption algorithm which is stored in a first storage means of the security module (50) and are output to the on-line data system (40), within which the authenticity of the person in possession of the card is verified. Provided the card has been identified as a card belonging to the data system of lower secrecy and security level (18), the data read from the card (22, 23, 24) are compared to the code input by means of the keyboard (46) by employing a verification algorithm, which is stored in a second storage means of the security module (50), in a comparator of the security module (50). As a result of the comparison within the comparator an authenticity code or, alternatively, a non-authenticity code is output to the off-line data system, exclusively. A coherent set of data and code is under no circumstances output from the apparatus to the data system of lower secrecy and security level. Consequently, the problem of eliminating transparency from the lower level secrecy and security data system to the high secrecy and high security data system is solved.

Abstract: A method and an electronic slide gauge serve to measure a length. The slide gauge comprises a rod with a longitudinal marking and a cursor, which is arranged on the rod in a longitudinally displaceable fashion and has two sensors that are mutually offset in the longitudinal direction in such a way that the zero crossings of the signals generated by the sensors do not coincide. In order also to be able to measure lengths in the presence of a considerable DC drift, the zero crossings (ND) of the signals are determined by firstly determining the maximum values (MX) and minimum values (MN) of the signal values (U) and then determining the zero crossings (ND) as an arithmetic mean value. By averaging a relatively large number of zero crossings, the respective zero level (UN) is then determined. <IMAGE>

Abstract: Heat is stored in a closed basin having a net inflow of relatively fresher water connected by a strait to a larger body of relatively saltier water by selectively controlling the exchange of water between the body and the basin as a function of the season of the year. In summer, the exchange of water is promoted thereby permitting relatively warmer and saltier water outside the basin to flow through the strait into the depths of the basin. In winter, the exchange of water between the basin and the body of water is suppressed thereby trapping warm, relatively saltier water in the lower regions of the basin, the warm water being available during the winter and being protected against heat loss by a surface layer of relatively fresher water. The heat thus stored can be utilized in various energy conversion processes such as heat pumps to raise the temperature to useful levels.

Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.
