Abstract: In an EEPROM memory cell of the kind which relies on tunneling action through a thin oxide layer to store charge on a floating gate, the floating gate and the channel regions of the memory cell are provided with additional doping of the same kind as in the substrate in order to raise the virgin state threshold voltage of the memory cell to a high positive value, such as 4 volts. Additionally, the overlap area between the control gate and the floating gate is reduced to the extent that the capacitance between the floating gate and the control gate is substantially equal to the capacitance between the floating gate and the substrate during programming, but the effective capacitance between the floating gate and the substrate is greatly reduced during erase mode. As a result, little or no tunneling occurs during programming and the threshold voltage level is the same as the virgin threshold value of the memory cell. However, during erase very efficient tunneling occurs from the floating gate to the substrate and the threshold voltage level decreases to a negative value. The difference between positive and negative values of the threshold voltage is comparable to that of conventional memory cells.

Abstract: @ An electron beam pattern transfer system is disclosed which includes a photoelectric transducing mask (20) disposed within a vacuum container and adapted to transfer a photoelectron beam pattern corresponding to a pattern of the mask onto a sample (24) according to an amount of an incident hight, a DC voltage generator (44) connected to vary a voltage applied between the mask and the sample, and a focusing coil (46) of a superconductive magnet for creating a magnetic field of a predetermined intensity between the mask and the sample. When a mask-to-sample distance (d) and/or magnetic field intensity varies undesirably, the variation is electrically detected by detectors (62, 82). In order to compensate for the defocusing of the photoelectron beam pattern on the sample (84) due to the above-mentioned variation, a microprocessor (90) automatically calculates an amount of correction with respect to the intensity of the electric field between the mask and the sample, on a real-time basis and supplies its control signal (92) to the DC voltage generator (44).

Abstract: The efficacy of plant and animal active substances, especially hormones, regulatory factors, transmitters, enzymes, and of vitamins and trace elements is improved by binding them to polypeptides, peptides and/or nucleotides as carriers and additives which are obtained from microbial, plant and/or animal macromolecules by chemical hydrolysis or enzymatic degradation. Alkalisation of the loaded carriers and additives, also using trace elements and possibly surface-active substances, counteracts the environmental damage of the flora. It is also possible to use energy-transferring systems. "Tree death" resulting from difficulty in adapting to environmental changes is a preferred area of use, but also likewise the improvement of the utilisation and efficiency of feedstuffs and resistance to infections and stress in the rearing of productive livestock and the prophylaxis and therapy of damage from ionising radiation and cytotoxic substances. The efficacy of drugs in human and veterinary medicine is improved and protracted. The products are added to the nutrient media in bacteriology to stimulate the growth of microorganisms, and in tissue culture to improve the growth of cell cultures and to retain the specificity and the cell-division capacity.

Abstract: A vibration type force detector in which the vibration string (1) is made of a platinum-based nickel-containing alloy. The magnitude of a force to be detected is obtained, as similarly as by a conventional vibration type force detector, through the measurement of a natural vibration frequency of a string vibrating with the force loaded thereto. However, the force detector using a Pt-Ni alloy vibration string (1) based on the invention makes it possible, for the first time, to apply a vibrational type force detector to a precision measurement of force or weight. Measurement with an accuracy of 10-<sup>5</sup> is made possible by the present invention.

Abstract: Pre-foamed particles are produced by dispersing resin particles, which contain nucleocells, in a dispersing medium in a closed vessel, heating the contents to a temperature of the softening point of the particles or higher and holding the contents at the temperature for a predetermined period of time while pressurizing the contents with an inorganic gas, and then opening the vessel at one end thereof so as to release the particles and medium into an atmosphere of a pressure lower than the internal pressure of the vessel, thereby causing the resin particles to foam. The above production process provides good pre-foamed particles with ease and without failure. It is also possible to avoid deleterious effects due to the swelling action of foaming agents.
