Abstract: In an arrangement according to the invention, two measurement electrodes (S1, S2) are arranged in a container (1) at different horizontal and vertical distances from an electrically conductive inner wall, connected to earth, of the container (1), one of which is in the region of the ice coating which forms. The measurement electrodes (S1, S2) pick off resistance values (RE, RW) of the ice and/or of the water which is located between the electrodes (S1, S2) and the container inner wall. 
<??>In order to cool the water, irrespective of its chemical-physical composition, suitable potentials are formed on the resistors (RE, RW), which potentials are supplied to a differential amplifier (DVK). A cooling set (M, VD) which acts on the contents of the container is switched on or off as a function of a comparison of the magnitudes of both resistance values (RE, RW).

Abstract: System for irradiating the surface of a substrate with atomic or molecular ions by rapid scanning of a beam in two dimensions over the surface of the substrate. A scanning system is shown for deflecting the beam in two dimensions relative to a reference axis and a magnetic ion beam transport system following the scanning system is arranged to receive the beam from the scanning system over the range of two dimensional deflections of the scanning system and constructed to impose magnetic field conditions along the beam path of characteristics selected to reorient the two-dimensionally deflected beam to a direction having a predetermined desired relationship with the axis in the two dimensions at the desired instantaneous two dimensional displacement of the beam from the axis, to produce the desired scan of the beam over the substrate. One scanning system includes sequential first and second time-variable-field magnetic scanners, the first scanner having a magnetic gap of volume smaller than that of the second scanner and constructed to scan the beam more rapidly than the second scanner. In another system, the scanners are superposed. The magnetic ion beam transport system presently preferred is a system producing a sequence of three or more quadrupole fields, implemented by a sequence of quadrupoles. Alternate structures are disclosed. The system is capable of depositing atomic or molecular ions with a desired angular and positional uniformity over a wide range of perveance including perveance above 0.02/M[amu] 1/2  (mA/keV 3/2 ) with a constant, adjustable spot size and small beam spread.

Abstract: A digitized image previewer framestore apparatus enables a photofinisher to rapidly view what is seen by a high resolution CCD image sensor (but at a lower resolution) on a preview display (40). A selected portion or selected portions of the imagery data derived by way of the array of pixel elements of the high resolution sensor are controllably coupled to a pair of 'ping-pong' write/read memories (121,123). The image resolution or storage capacity of each of memory is less than that of the high resolution CCD sensor and is considerably less than that of the 3072 X 2048 resolution of a high resolution color output image to be stored on compact disc. Depending upon the selected portion of the image incident on the CCD sensor is to be viewed, respective pixel and line rate clocks for the CCD sensor are subsampled and coupled to address generating counters used to access the ping-pong memories. As a result, only those CCD pixels for which (subsampled) clock signals have been generated will be displayed. By 'ping-ponging' write-in and read-out of the memory pair, a first low resolution image may be written into one of the memories, while a second low resolution image is being rapidly read out and displayed. Then, at then end of the write-in frame interval, the contents of the newly loaded memory are rapidly read out to the preview display, while the next selected low resolution portion of the sensor image is being written into the memory the contents of which were previously read out and displayed.

Abstract: An improvement is proposed in an electrostatic chuck, which is used in holding and transporting, for example, a semiconductor silicon wafer under processing in the manufacture of electronic devices, having an internal electrode layer sandwiched between two dielectric layers of a ceramic material. The disadvantage caused by the inherent porosity of the ceramic material can be dissolved by the invention according to which the pores are filled with a thermally decomposable liquid compound of silicon, aluminum and the like and then the ceramic material is heated in an oxidizing atmosphere so as to decompose and oxidise the impregnant compound into the oxide formed  in situ  and filling the pores so that the electrostatic attractive force can be increased as a consequence of the increase in the effective dielectric constant along with high resistance against any corrosive gaseous atmosphere as compared with conventional pore-filling materials such as epoxy resins.

Abstract: Switched current circuits include current memory cells which store analogue currents by means of the charge on the gate source capacitance of an MOS transistor. A source of inaccuracy in these circuits is switch charge injection into the gate source capacitance. It has been found that the error current produced by a single such current memory cell has a peak value at one value of stored current, the peak being relatively broad and symmetrical over a significant range of currents (Figure 3b). 
     When two current memory cells (S1,T1,C1; S2,T2,C2) are connected in cascade this error may be cancelled. In order to produce equal errors an optimum bias current needs to be generated which will depend on parameters which are variable in integrated circuit manufacturing processes but which will be relatively constant within an individual integrated circuit. The two cascaded current memory cells (S1,T1,C1; S2,T2,C2) include controllable bias current sources (T16,T17) and a control circuit (10) is provided to control the current sources (T16,T17) so that the current memory cells (S1,T1,C1; S2,T2,C2) operate at the optimum bias current. The control circuit (10) comprises two further current memory cells (S11,T11,C11; S12,T13,C12) connected in cascade. Two different value current sources (T10,T12) are provided and the error current due to switch charge injection is used to charge a capacitor (Cx). The voltage across this capacitor (Cx) provides the control for current sources (T16,T17) and also current sources (T14,T15). The control feedback loop comprising current sources (T14,T15) and capacitor (Cx) causes the bias current to approximate to the optimum value.

Abstract: To improve pictures to be displayed on a display screen of a display device, it is known to use scan velocity modulation. In scan velocity modulation the (horizontal) deflection rate of the electron beam(s) is modulated with the luminance component of the video signal. As a result of scan velocity modulation the information of the video signal will no longer be displayed at the correct position on the display screen. By using the modulation signal applied to the scan velocity modulator also for modulating the (read) clock rate of the video signal from the memory, it can be ensured that the video signal and the (modulated) deflection signal are always in synchronism with each other.
