Abstract: A photoelectric sensor having a photoconductive layer on an electrode and used to form information on an information recording medium. The photoelectric sensor is semiconductive and has such a function that when a voltage is applied between the electrode of the photoelectric sensor and an electrode of the information recording medium while information exposure is being carried out, or when information exposure is carried out with a voltage being applied between the two electrodes, information can be recorded on the information recording medium with an electric current amplified to a level higher than the intensity of a photoelectric current induced by the information exposure, and that even after termination of the information exposure, when the voltage is continuously applied, the photoelectric sensor shows electrical conductivity and continuously effects information recording to the information recording medium. The photoelectric sensor has a photo-induced current amplifying layer provided between the electrode and the photoconductive layer, thereby enabling an image free from unevenness and noise to be formed with high sensitivity.

Abstract: In the manufacture of active-matrix liquid-crystal displays or other large area electronic devices, self-aligned photolithographic process steps (Figures 2 and 5) are used to define first and second gates (1 and 2) of a TFT from first and second conductive layers (21 and 22). In the first self-aligned step a positive photoresist (26) is selectively exposed by illumination (31) through the substrate (1 0) while using opaque areas (3 and 4) of the TFT source and drain as a photomask; after developing this selectively-exposed positive photoresist (26) and depositing the first conductive layer (21), a lift-off process is used to leave a first area (21a and 21b) of the first conductive layer where the first and second gates (1 and 2) are to be provided. Then a part (21b) of this first area is removed to leave a smaller, second area (21a) of the first conductive layer (21) for forming the first gate (21). Thereafter the second self-aligned photolithographic process step is carried out by selectively exposing a second photoresist film (27) by illumination (32) through the substrate (1 0) while using opaque areas of the source and drain and first gate as a photomask. By developing this selectively-exposed second photoresist (27), a second photoresist area (27a) is formed for defining an area of the second conductive layer (22) which provides the second gate (2). The second photoresist (27) may be of either the positive or negative type. One of the gates (1 and 2) may be used as a field-plate or as a tetrode gate. The use of this sequence of process steps, including the two self-aligned steps, reduces the parasitic capacitances and capacitive couplings in the TFT structure, so permitting fast and stable circuit operation of the TFT in the device.

Abstract: An electronic graphic system for modifying image pixels includes a framestore 21 and a pipeline brush processor 22. Image pixels are read out of the framestore 21 in batches and applied to an input of the brush processor 22. Other data representing colour shape and pressure of a line drawn by a user on a touch tablet 17 by way of a stylus 18 is also input to the processor 22. As the pixels pass through the processor 22 they are modified by the other data. Batches of modified pixels are written back to the framestore 21. The reading and writing of pixels from the framestore 21 is interleaved with the reading of pixels for display as an image on a monitor 16. 
     The system also includes an arrangement for interpolating stylus pressure to remove visible discontinuities or other changes in the drawn image resulting from significant changes in stylus pressure. 
     An improved zoom facility enables a substantially continuously variable zoom factor to be defined thereby to avoid large changes in scale during a zooming operation. 
     An arrangement for adjusting numerical values associated with some functions or features of the system allows the user to control the values solely by movement of the stylus over the touch tablet.

Abstract: An on-screen display system for displaying instructions for guiding a user to utilize various features of a consumer electronics product such as a television receiver or VCR, includes a memory (21) for storing both uncompressed text data and compressed text data, and an associated microprocessor (19) for retrieving the text data, decompressing it if necessary, and presenting it to a display buffer (23). Text data compression is in part accomplished by a dictionary containing text data representing commonly used text "strings" comprising one or more words which is stored in the memory (21). Code words related to the location of respective dictionary entries in memory are substituted for respective uncompressed text data. Text data compression is also accomplished by substituting a format change code word indicating that adjacent text data representing a first string of text with a first format, such as all lower case or mixed case, is to be converted to text data representing a second string of text with a second format, such as all upper case or title case. In this way, text data representing text differing only in format only needs to be stored once. The format change code word is employed both in the uncompressed text data portion of the memory and in the dictionary portion of the memory and the text data, whether uncompressed or compressed, is retrieved and formatted for display in the same manner.

Abstract: A difference signal generated in a prediction encoding process is block-segmented by a block segmenting circuit 2. Thus, the level distribution of the block-segmented difference signal is concentrated to a narrower portion than the level distribution of one entire screen. Reference values DR and MIN of each block of the difference signal are detected. A quantizing step width Δ and shift data ΔS are determined corresponding to such reference values and the number of quantizing bits N. A quantizing circuit 6 quantizes the difference signal with Δ. The difference signal is shifted and quantized so that the level 0 of the difference signal is obtained as 0 on the decoding side. A flag FLG and Δ that represent the quantized value of the level 0 are transmitted as side information along with the quantized value Q.

Abstract: The invention relates to a method and apparatus for linearizing a flow velocity sensor based on pressure difference measurement. According to the method, such a difference of two pressure signals (4, 5) is measured from the flow under measurement that is proportional to the square of the flow velocity, the difference of said two pressure signals (4, 5) is measured using a micromechanically manufactured symmetrical capacitive differential pressure sensor (20) based on the force balance principle, in which sensor the pressure-induced deviation from force balance is compensated for by inducing on the pressure-sensing diaphragm (23) of said differential pressure sensor (20) a force-balance-restoring electrostatic pressure so that the pressure-sensing diaphragm (23) is subjected to the force-balance-restoring electrostatic force, whereby the amplitude of the force-balance-restoring electrical feedback control signal, which also acts as the system output signal, is directly proportional to the square root of said difference of said two pressure signals, and thus, a linear function of the flow velocity. According to the invention, said feedback control voltage depending on the direction of the pressure difference is applied only to either of the stationary electrodes (21 or 22) disposed on the same side relative to the sensing diaphragm so that the electrostatic force of attraction thus induced acts counter to the force generated by the pressure difference under measurement, whereby the polarity of the system output voltage signal is dependent on the direction of the flow.

Abstract: A lead on chip (LOC) semiconductor leadframe package provides notched lead-fingers (60) to eliminate mechanical shear-stress at the peripheral edge of a semiconductor chip (52). Opposite rows of substantially flat cantilevered lead-fingers (60) are attached by double-sided adhesive tape (55) in thermal contact with the active face of a chip (52). The lead-fingers (60) are routed in personalized paths over the face of the chip (52) to cover a large surface area to aid heat dissipation. All wirebond connections (63) between the lead-fingers (60) and the chip (52) are made at a centerline connection strip running down the center of the chip (52). Each of the cantilevered lead-fingers (60) has a notched portion positioned directly over the vulnerable peripheral chip edge to reduce thermal, mechanical shear-stress. Additionally, since corrosion typically follows a lead path, the notch provides an increasing path length to prevent corrosive ingress over the chip face.
