Abstract: A nonstandard spherical resonator which produces laser radiation having spherical modes of oscillation is formed entirely within a sphere (12,24) of laser gain material. The resonator is pumped to produce the spherical modes. By pumping an isotropically coated sphere (12) at normal incidence the entire sphere forms the resonator, and the laser radiates uniformly in all directions as from a point source (20). By pumping obliquely to totally internally reflect the laser radiation at the surface of the sphere (24), or by applying an equatorial coating (36) on the sphere to internally reflect the laser radiation, a toroidal region (30), within the sphere forms the resonator. The pumping volume can be controlled so that the laser radiation is single longitudinal mode and single frequency by limiting the active mode volume. Prisms (32,37) can be used for input and output coupling to the toroidal resonator; an optical fiber (34) can also be used for output coupling. A compact laser design uses a Nd:YAG sphere pumped by a laser diode. The spherical resonators can be used for tracking, holography, levelling and ring laser gyroscope applications. The toroidal resonator forms an ideal ring laser for use as a gyroscope; a sphere (50) with three orthogonal toroidal resonators (44,46,48) provides three degree of freedom measurement capability.

Abstract: The present invention relates generally to a method for protecting an electric motor against overheating. The process consists in: - initially programming a value of nominal operating current (IN) for the motor; - storing the value of the nominal current (IN); - initially programming a shaft height value (H) representing the thermal time constant (O) for the motor; - storing the shaft height (H); - then, measuring the value of the effective current (I1EFF; I2EFF; I3EFF) to at least one phase of the motor; - calculating, as a function of the value of the nominal current (IN), of the shaft height (H) and of the measured value of the effective current (I1EFF; I2EFF; I3EFF), a value (Y) representing the heating of the motor; - comparing the calculated value (Y) of the heating of the motor with an initially programmed heating value (YTH); - producing a control signal for stopping the motor when the calculated value (Y) of the heating is greater than the programmed heating value (YTH). The invention finds application in particular for any type of industrial motor used in the transport, aeronautical or marine industry. <IMAGE>

Abstract: In particular, thermoplastic or thermoset elements of complex geometry often have inner lumina of small cross-section. The cleaning of such elements is usually performed by flushing with a liquid rinsing medium, the result often being unsatisfactory since residually attached particles are not taken along and are only dislodged later when the element is put to its intended use. According to the invention, by ultrasonic bombardment of the flowing rinsing medium and/or of the element, similarly oscillating cavitations are produced in the flushed inner lumina of the element. This makes more intensive cleaning possible. The associated device is provided with an ultrasonic generating device with sonotrode (10), which either has in its direction of oscillation, at least partially, a central bore (11) for the rinsing medium to flow through or its effective surface (113) lies in the near field range for the inner lumina of the element (1, 100) to be flushed. <IMAGE>

Abstract: The low specific contact resistance of a contact (16, 26) preferably consisting of doped polycrystalline silicon on a surface (15) preferably consisting of monocrystalline silicon (21, 22) is obtained by the fact that, after the contact material layer (16) has been applied, silicon ions (17) are implanted in the polysilicon (16)/silicon (21, 22) boundary area (15) and subsequently a tempering treatment is carried out by means of which the implanted dopant ions (19a, 19b) are activated at the same time. Due to the implantation of the silicon ions (17), the oxide layer at the boundary area (15) is broken up and low stable contact resistances are obtained. The method is used in the production of contacts, particularly so-called buried contacts in complimentary MOS transistor circuits. <IMAGE>

When the output intermediate potential is higher than the second reference potential, the comparator circuit outputs a second control signal at the level of the power source potential level to a second  MOS  transistor (M10) supplied with ground potential to lower the intermediate output potential.

Abstract: A method of linear interpolation comprises precalculation of interpolation contributions relating to all the possible locations for the points of an elementary mesh. The positions of these locations are determined as a function of a fineness of interpolation to be obtained. It is shown that this precalculation can be obtained without significantly enlarging the memory of an apparatus which uses it. Moreover, the speed of execution achievable allows expansion of definition, to flight, of poorly defined images to be visualised into well defined images.
