Abstract: The present invention relates to an improved heat pump system of a heating system which also comprises a utilization circuit. The heat pump system comprises a generator (2), an absorber (1), a condenser (5) and an evaporator (7), and the utilization circuit for circulation of a heat carrier medium comprises heat exchanger means (1a, 5g, 15, 17) for removing thermal energy from the heat pump system. 
     To supplement the thermal output of the heat pump system, when the utilization circuit requires a greater thermal output than can efficiently be achieved by the heat pump system alone, a supplementary condenser (25) is proved in the generator, the condenser comprising a heat exchanger - (25a) in heat exchange with vapour in the generator which can be connected in the utilization circuit by operation of a valve (WV) when additional thermal energy is required. Opening of the valve (WV) occurs simultaneously with an increase in the energy provided to the generator.

Abstract: An infinite impulse response (IIR) filter is operative to filter an input signal (x(n)) that comprises a sequence of digital words spaced in time by an interval T. The filter includes delay means (32, 34, 36) that delays the input signal by successive increments of time equal to T so as to cause the production of a series of relatively delayed signals (A,B,C,D) in which each signal is delayed by T with respect to the previous signal in the series. IIR processing units (38,40) receive respective groups (A to C and C to D) of the series of signals, the groups being offset with respect to one another by one word. The units (38, 40) are operative during each of plural successive clock periods equal to 2T to process respective sets of words obtained from the respective groups (A to C and C to D) of the senes of signals so as to produce two output words (F, H). A multiplexer (54) combines each two output words (F, H) produced during each clock period equal to 2T to constitute a filtered output signal (y(n)) comprising a sequence of output words spaced in time by the interval T.

Abstract: Transistors (10) having lateral gaps between their source and drain and the gate are interconnected in a ROM to receive program code. 
     In one embodiment of the invention (Fig. 3), the gaps of selected transistors (42) are subjected to a phosphorous implant (44) to create lightly doped n⁻ regions (26,28) connecting the source (18) and drain (20) to the gate (14), and function normally. The other transistors (40) do not receive the phosphorous implant, and thus have a higher threshold voltage. 
     In another embodiment of the invention (Fig. 2) all of the transistors receive the phosphorous implant to create the n⁻ regions (26,28) connecting the source and drain to the gate, and the n- regions of selected transistors (32) are counter-doped with a boron implant (34) so as to raise their threshold voltages, while the other transistors (30) are not counter-doped and function normally. 
     In both embodiments, programming can occur late in the processing of the ROM.

Abstract: A composite ceramic material having improved properties is disclosed as well as several processes for preparing the same. The composite powder is substantially comprised of zirconia and spinel phases, produced by precipitation and calcination of the precipitate of the oxide forming precursor salts. A preferred process for introducing the zirconium is as a soluble and/or decomposable salt during precipitation of the spinel forming hydroxyl or halo hydroxyl spinel forming salts. The zirconium salt decomposes to zirconia during calcining and/or sintering of the powder resulting from the precipitation. A preferred composite is that obtained from magnesium and aluminum salts, resulting in a MgAl0 4  spinel and intimately admixed Zr0 2  which may contain a stabilizing agent.

Abstract: Semiconductor devices are described including a structure of alternating first and second layers of Group-IV materials which together form an ordered composite structure having a crystallographic unit cell which differs from the unit cells of both the first and second layer materials. Structures in which both first and second layers are not more than 8 atomic monolayers thick have properties (such as, e.g., electronic or optical properties) which are significantly different from those of previously known Group-IV semiconductor materials and structures. As a result, structures of the invention give rise to novel device applications. In the case of germanium and silicon layer materials, the number of monolayers in first and second layers strongly affects electroabsorption properties. A structure of alternating first layers of 4 atomic monolayers Ge and second layers of 4 atomic monolayers Si is of particular interest for photodetector use on account of strong optical absorption at wavelengths near 1.6 micrometer.
