Abstract: Deep cells are formed on a silicon substrate by depositing in a recess in the substrate a body of a-silicon, e.g. by plasma enhanced chemical vapour deposition, at a temperature below 550 °C. The layer is recrystallised to a single crystal layer by heating the structure to a temperature between 550 and 900 °C. The technique overcomes the problems of wafer distortion experienced in conventional high temperature epitaxial growth.

Abstract: A composition of matter consisting of recombinant human immune interferon having a near-UV circular dichroic spectrum in aqueous solution at neutral pH with positive bands at about 259 nm, 266 nm, 280 nm, and 287 nm, and with shoulders at about 270 nm and 292 nm. Also disclosed is a method for purifying human immune interferon in which proper refolding of the interferon is accomplished by unfolding in a denaturant, such as urea, dilution in ammonium acetate to approximately 0.18 mg/ml of interferon (or less), and dialysis of the solution. The properly folded, purified product which results has a four- to eight-fold greater activity than the aggregate which otherwise results.

Abstract: An electronic programmable thermostat for the control of a furnace or air conditioner is useful as a re­placement for a conventional non-programmable thermo­stat and mounts on the non-programmable thermostat's wall plate (12) to achieve support, electrical con­nection with the load and power supply, and the use of certain manual controls supported on the wall plate (12). The programmable thermostat employs a circular printed circuit board (50) supporting its electronic components, which include a potentiometer (62) for operator adjustment of desired temperature. A flat circular knob (80) supported on the potentiometer shaft (78) and an annular bezel cover the thermostat and allow access to the manual controls supported on the wall plate. The potentiometer (62) and a temperature sensing thermistor (110) control the frequency of a pulse generator (112) which provides input to a counter (114). The resulting digital signal (114) is compared (in 116) with a digital signal (120) generated under control of a clock (128) and manually actuable programming switches (56), to generate an output control signal for the load (122). Predetermined temperature programs of desired temperatures over a repetitive time cycle are stored in a memory (120). A manually operable program selector (56) enables recall of a desired temperature for a particular time from the memory. This desired tempera­ture is compared to the ambient temperature in order to generate control signals for the temperature modifying device.

Abstract: There is disclosed a priority order determination method and an apparatus therefore for determining the priority order on the basis of plural kinds of priority order determination systems. This novel priority order determination method comprises: a first step of receiving a plurality of request signal groups to compare request signals belonging to the respective request signal groups with each other on the basis of a first kind of priority order determination system, respectively, thus to determine priority request signals of higher priority order; and a second step of comparing the priority request signals of the respective request signal groups with each other on the basis of a second kind of priority order determination system, thus to determine a highest priority request signal of the highest priority order. This concept is readily expandable to priority processing systems in which three kinds of priority order determination systems or more are combined with each other. For such priority order determination systems, there may be adopted the fixed priority determination system, the equal opportunity priority determination system, the round-robin priority determination system, and the like.

Abstract: This invention provides a snap-action heat responsive device employing a bimetallic strip which is typically used with a thermostat, a temperature-protecting apparatus or the like. Two elongated portions of the bimetallic strip oppose each other so that they may be deflected in the opposite directions to double the amount of displacement of the bimettalic strip and in addition so that they may be urged in the opposited directions. This enables swift reverse of the bimetallic strip and also production of a small-sized bimetallic device suitable for use as a miniature current limiter for handling an electric current of about one ampere. It is therefore possible to produce a snap-action heat responsive device having a high sensitivity with respect to variations in temperature.

The inventive filter unit includes an analog-to-digital con­verter (21) for converting a signal representing a phase difference between a reference horizontal synchronizing signal and an a horizontal synchronizing signal extracted from the reproduced video signal, a digital filter (22) unit to which the phase­-difference signal is applied, a digital-to-analog converter (23) for converting the digital output from the digital filter back into an analog signal, and an analog low-pass filter (24) which smooths the analog output from the digital-to-analog converter (23). In accordance with the inventive concept, in the output signal from the digital-to-analog converter, the frequency response characteristic in a relatively high frequency band is deter­mined by the digital filter, while the characteristic in a relatively low frequency band is determined by the analog low-pass filter.

Abstract: Method of detecting the INFO_1 signal pattern which avoids false activation of a data transmission line caused by noise on the line. An initial line sampling rate four times the nominal 192 kbs line rate is used to detect a HIGH mark to avoid the difficulties resulting from sampling right at the edge of a mark. Subsequent sampling is done at the nominal line rate to detect two opposite polarity marks out of every consecutive eight-bit time periods. If six consecutive eight-bit time periods are detected, each having its HIGH and LOW marks in the same relative positions, the line is activated. The method is readily implemented as a set of three "state machines" and consequently can be constructed from programmable logic arrays.

Abstract: This invention relates to a recording member for the electrographic recording of toner images thereon. 
     Kotz, U.S. Patent No. 3,816,840 discloses an electrographic recording process and apparatus in which a dielectric recording member is arranged between two electrodes. 
     Selection of a recording member for use with the foregoing apparatus may be constrained by at least three factors:
     (1) Electrical charge must be essentially completely removed from the recording member within one operating cycle of the process;   (2) Durability of the recording member must be sufficient in order to allow the process to be economically feasible;   (3) Contrast between toner powder and the recording member can be specified to be high, e.g. at least 0.6 optical density units.   
     This invention provides a recording member comprising a conductive substrate having a dielectric coating thereon. The dielectric coating contains a charge build-up inhibitor to allow the recording member to be used for a large number of cycles of image-formation and image-removal with virtually no build-up of charge or deterioration of image quality, and the surface of the coating is sufficiently durable to allow the recording member to be used repeatedly before the recording member needs to be replaced.
