Abstract: A MMIC variable attenuator uses depletion mode Schottky gate FETS as variable conductance devices in a "π" configuration to vary attenuation as a function of a DC control voltage. Attenuation is flat within ± 1dB, VSWR is ≦ 2:1 throughout the operating frequency and control voltage range, and about 12 dB variable attenuation is provided. The "π" is formed by FETs (100, 200) in shunt to ground between attenuator input and output, and by a FET (300) in series between input and output. Resistors and an inductor means (600) connected in parallel with the series FET (300) extend attenuator bandwidth to 20 GHZ and improve attenuation linearity versus control voltage. A resistor in series with each shunt FET (respectively also 615 and 630) improves linearity. The typically 0 to +3 VDC control voltage is applied to the FET gates and drain/source leads permitting attenuation control with a single control voltage (Vc). RF power capability is increased without degrading RF performance by using multi-gate FETs wherein the ratio of gate width to number of gates is maintained substantially constant compared to a single-gate FET. Series-connected FETs further increase attenuator RF power capability. Operating from 2-20 GHz, embodiments using a single control voltage handle about 30 mW RF input power and use single-­gate and dual-gate FETs, and handle about 250 mW RF input power and use triple-gate FETs. A third embodiment, operating from DC-20 GHz and handling about 500 mW RF input power, employs dual-gate FETs throughout and requires two complementary control voltages (Vc and Vc').

Abstract: A protection circuit is inserted between a signal input pad (IN) and an internal circuit. The protection circuit includes a parasitic bipolar transistor (116) which is obtained by forming high-impurity concentration semiconductor regions (112, 103, 114) in the major-­surface region of a substrate (101). In practice, it is hard to provide a parasitic bipolar transistor of a suf­ficiently large size, since the reduction of the size of a chip is a recent trend. With this in mind, a third semiconductor region (117) serving as an electron-­trapping region is formed in a region outside of the location where the parasitic bipolar transistor is formed. If an excessive voltage produced by ESD or the like is applied to the pad (IN), and the excessive volt­age uncontrollable by the parasitic bipolar transistor, the third semiconductor region (117) absorbs the exces­sive voltage. In particular, where the current capacity of the parasitic bipolar transistor (117) is small, the third semiconductor region (117) reliably prevents electrostatic destruction of a circuit element (111). Accordingly, the protection circuit enables the para­sitic bipolar transistor (116) to be reduced in size, thus contributing to miniaturization of a chip. More­over, the protection circuit is reliable in operation.

Abstract: Pusher blades are used in analyzers to transport test elements from one location to another with the analyzer. As analyzers become more involved in their processing, pusher blades must traverse greater distances. However, this tends to have the result that the dimensions of the analyzer need to be increased to accommodate increases in pusher blade length. Described herein is a pusher blade (10) and its housing (40, 42, 44) in which the blade (10) has a stiff front end (12) for engaging slide-type test elements (E, E′), and a flexible body portion (16) and back end (14). The housing (40, 42, 44) forces the blade (10) to curve through an angle, preferably about 90°, to minimize the extension in one direction which the blade (10) would have if it were entirely rigid. The housing (40, 42, 44) is shaped to produce the curve which has a radius of curvature (R) and also to house drive means (30, 32) for the pusher blade (10).

Abstract: The invention relates to the production of plaster elements having decorative visible faces of high surface quality, widely used in the construction industry. The plaster elements can be made in various configurations, in a single colour or marbled. This is achieved according to the invention by a method in which a multi-layer moulding material consisting of a water/plaster mixture and dried plaster powder is covered in a mould with a hygroscopic and/or open-cell material of low compressibility and then water-compacted by pressure elements with simultaneous removal of air and subsequently compressed with the exclusion of air. A positive pressure is built up in the moulding material and the material covering it and this is maintained at least in part until dimensional stability of the plaster element has been attained. The plaster element is then released with the aid of the pressure elements. The device according to the invention is distinguished by the fact that an upper part is designed as a holder with pressure elements articulated on it on the top and bottom. The lower part for holding the moulding material comprises a dimensionally stable frame with an integrated separating frame and is supported in airtight fashion on the mould bottom. The upper part and lower part can be locked together airtightly via a seal. <IMAGE>

Abstract: The invention relates to a threshold comparator intended especially for counting the number of times an alternating periodic signal exceeds a particular level. …<??>In order to avoid false counts due to fluctuations in the potential of the supply and of earth, a double threshold comparator is provided according to the invention, constituted by a first inverter (T1, T'1) and a second inverter (T2, T'2) receiving the signal to be detected via a capacitor (C). The joint inputs of these inverters are biased by a bias voltage source Vbias supplied by a third inverter (T3, T'3) whose output is looped back on the input. The geometries of the transistors of these three inverters are chosen in the following way: the ratio between the geometries of the two transistors of the first inverter is slightly different from the corresponding ratio for the second inverter, and the ratio for the third inverter lies between these two first ones. This makes it possible to have two closely-spaced trip thresholds which immunise the comparator against noise. …<IMAGE>…

Abstract: The power converter of the invention relates to a small-sized highly efficient power converter for generating an a.c. voltage output of multiple levels with less harmonic content. In the power converter, a d.c. voltage source (1) is separated into plural sections by series connected voltage dividing capacitors (3a, 3b, 3c) and multiple levels of a.c. output voltage are obtained from the divided d.c. voltage by on-off control of switching devices (2a, 2b, 2c). The power converter may have plural sets of the voltage dividing capacitors disposed separately adjacent to each switching devices, and series connection point (Oca, Ocb, Occ) of each set of the voltage dividing capacitors may be connected to division points (Osa, Osb, Osc) of the corresponding switching devices of each phase. The voltage dividing capacitors may be connected with each other at their series connection points. Thereby, the arrangement may make wiring length short and equal between the switching devices and the voltage dividing capacitors for each phase so as to reduce a loss in the snubber circuit, resultingly an a.c. voltage output (Ta, Tb, Tc) with less harmonic content is obtainable.
