Abstract: The present invention refers to a biomass of T. chuii and a pharmaceutical composition comprising a biomass of T. chuii for use in the treatment of infertility in a male subject. It also refers to a method for increasing the quality of the semen of a male subject having normozoospermia, not having hypospermia and not having a disorder characterized by a high percentage of sperm DNA fragmentation (SDF), that comprises the administration of a biomass of T. chuii.

Abstract: Enclosure for holding an electrical device with dual access panels for safely limiting access to the device while allowing maintenance thereof. The housing defines an access opening with a limited accessing construction thereover. Interior and exterior panels are included each movable to be closed and opened. The interior panel is preferably transparent to facilitate viewing therethrough. The exterior panel is preferably metal and is hinged to the housing for movement between closed and opened positions. Individual accessing apertures can be defined in the interior and exterior panels to allow localized access by servicing personnel. Specific positioning of the access opening in the interior and/or exterior panels provides access to limited areas of the electrical device within the housing and prevents access to other areas for safety. The interior panel can have indicia imprinted thereon to facilitate servicing.

Abstract: A method and apparatus for generating a dynamic focus signal for focusing an electron beam on a CRT, the signal being proportional to a function of the vertical deflection Y and horizontal deflection X of the beam according to X.sup.2 +Y.sup.2 +X.sup.2 f(Y) or X.sup.2 +Y.sup.2 +Y.sup.2 f(X), where f(Y) or f(X) is a positive symmetric function. The resultant dynamic focus signal has increased magnitude as the beam moves away from the center of the screen, thus providing proper focusing at the corners of the screen as well as at the center and sides of the screen.

Abstract: The current in the deflection coil of a video display system is converted into a DC voltage and applied to a peak detector. Peak values of the DC voltages as stored by the peak detector are amplified and then compared with a reference voltage at the input of a comparator amplifier. The comparator amplifier provides an output as a base drive to a regulating transistor that has an emitter-collector junction in series with the deflection coil and an unregulated source of DC power.

Abstract: Picture quality in a cathode ray tube image display system is improved by a switching amplifier providing output pulses with fast rise and fall times. First and second switching signals are applied as base drive voltages to first and second transistorized differential amplifiers having one transistor of each amplifier with a common collector electrode connection. The interconnection of the collector electrodes forms a summing junction coupled to an output transistor connected in a common base configuration. In series with the output transistor and a power supply is a load resistor that, in conjunction with the output transistor, establishes an output voltage dependent on the sum of the currents generated by the first and second differential amplifiers. Also connected to the output transistor is a clamping network comprising a diode biased at a first voltage level that is lower than the voltage level of the power supply connected to the load resistor.
