A galvano-magneto effect device comprised of a semiconductor element and lead frames, the element being provided with electrodes which are coated with a thermally fusible conductive material and are formed at the terminal sections of the element and the conductive lead frames being made by reducing the thickness of the end portions which are to be coupled to the electrodes and coating them with a thermally fusible conductive material.

A nucleotide selected from the group consisting of 3'-deoxyguanosine-5'-monophosphate, 3'-deoxyadenosine-5'-monophosphate and pharmaceutically-acceptable salts thereof enhances, when administered to a tumor-bearing animal under an anti-tumor treatment, the anti-tumor effect due to the anti-tumor treatment. The anti-tumor treatment comprises irradiation of a tumor site of the animal or administration of an anti-tumor agent to the animal.

A nucleoside selected from the group consisting of 3'-deoxyguanosine and 3'-deoxyuridine enhances, when administered to a tumor-bearing animal under an anti-tumor treatment, the anti-tumor effect due to the anti-tumor treatment. The anti-tumor treatment comprises irradiation of a tumor site of the animal or administration of an anti-tumor agent to the animal.

A closed loop control apparatus utilizes a cooling effect sensor to measure the cooling capacity of a fluid in a supply conduit connected to one or more thermal loads. The sensor includes an electrical heater that is regulated to heat a sampled portion of the cooling fluid at a known rate, and a temperature sensor positioned downstream of the heater to measure the temperature of the heated fluid and thereby determine the cooling effect or capacity of the fluid. A control signal developed by the ...

Multiple effect evaporator apparatus includes a plurality of evaporator chambers, a plurality of thin-film flow-down type vertical heat exchange tubes the ends of which are connected to partition plates which divide the apparatus into the various evaporator chambers, a vessel disposed above the heat exchange tubes for receiving a solution, pressure difference maintaining means and solution distributing means interposed between the vessel and heat exchange tubes whereby evaporation and uniform di...

A tremolo effect producing system comprises, in combination, a closed housing, an electro-acoustic transducer such as a loudspeaker supported in said housing for revolutions in a plane and capable of converting an electrical audio signal to an audible sound, a plurality of acousto-electric transducers such as microphones provided at different positions in said housing to face said electro-acoustic transducer successively as the latter is rotated and capable of converting audible sound to an elec...

A Gunn effect triode is utilized to provide a power divider. The power divider may, for example, be provided with a main branch from which depend two or more legs and from each of which a replica of the input signal is obtained. Since a Gunn effect triode is an amplifier, the output signal is amplified whereas the conventional divider experiences a substantial loss. The power divider is characterized by its extremely small area which may be on the order of 25 microns squared and by its increased...

A chromakey effect apparatus including a color-killing subcarrier-generating circuit which generates a color-killing subcarrier which completely kills color even when the hue or saturation of the chromakey area is changed and which also kills the color while simultaneously converting the color. Furthermore, the apparatus is capable of both chromakeying only the chromakey area even when there are many portions having the same color as the chromakey area, and also chromakeying a desired portion ev...

A lift-producing arrangement suitable for driving a boat by the Magnus effect comprises an elongate tubular envelope mounted for rotation about its longitudinal axis. A drive is provided to rotate the envelope. The envelope is of flexible material, e.g., canvas, to achieve improved performance. Preferably, the envelope is held erect by inflation. The arrangement may be used in addition to a conventional screw-propulsion system for increased fuel economy.

A wheeled vehicle has an undertray shaped to form a venturi duct with a road or like surface over which the vehicle moves, the undertray being carried in substantially fixed relationship with the wheels, so that the vehicle chassis or body can move relative to the wheels without substantial alteration of the shape of the venturi duct. The undertray can comprise the lower wall of a shell enclosing the vehicle body or chassis.
