Abstract: Provided is a color cathode-ray tube with a magnetic shield member which is capable of efficiently reducing only the amount of mislanding caused by the external magnetic field applied in one direction by effectively utilizing the shape effect of a magnetic substance and which can be readily designed. A U-shaped magnetic substance is formed by curving an elongated magnetic substance into a U-like shape. One end of the U-shaped magnetic substance is fixed to a long side wall side of a frame, while the other end thereof extends toward an electron gun. The U-shaped magnetic substance is magnetized therealong due to the shape effect thereof, concentrating an induction field on the area surrounded by the U-shaped magnetic substance. Thus, a great shield effect can be obtained. Further, the U-shaped magnetic substance is readily magnetized in a special direction due to its shape anisotropy.

Abstract: An apparatus and method for thermostatically controlling the operation of a multiple speed fan and light assembly by inputting a desired temperature range and airflow direction for each fan speed and by inputting a single number for controlling the on time and duration of the light assembly.

Abstract: Multiple concentric, triangular cross-sectioned fluorescent lamp tubes, located substantially in the same plane with respect to each other, are utilized in appropriate assemblies for: 1) a direct screw-in replacement for reflective incandescent lamps and; 2) recessed ceiling fixtures that are typically hardwired. The inherent triangular geometries of the concentric, substantially same plane lamps create mutually benefiting reflecting surfaces to maximize the net light output. The triangular geometry enables light from two sides of the fluorescent tubing to be efficiently cast if desired (or muted by absorbent housing wall if desired). The remaining side, or base, of each triangular tube produces light that is redirected by opposing, intersecting, coaxial, conical reflectors arranged to direct the light through the unobstructed center of the concentric tubing arrangement. A transparent collimating structure adjacent to the triangular tub bases is used to enhance control of the light emanating from the base.

Abstract: To prevent corrosion of molybdenum connecting pins or wires extending from elt-sealed ends of high-power lamps, the region immediately adjacent the exit points from the melt-sealed end are cooled by a cooling gas, for example air or an inert gas such as nitrogen. The cooling gas is applied by cooling ducts which are made of metal and, simultaneously, provide for electrical connection of electrical energy to the connecting leads. Cooling gas can be introduced either through terminal pins or rods into the tubular elements, or the tubular elements can be connected, as usual, to the part-solid terminal pins or rods and additional gas connections are passed through the base through the tubular elements to supply cooling gas.

Abstract: There are provided a cathode-ray tube display unit which can be manufactured with reduced weight and cost and which can have a screen plane flattened without the use of any metal band, and a method of making the same. The screen panel is previously deformed by the use of a jig and then sealingly connected to a funnel. After the jig has been removed, the interior of the display tube body is extracted to form a vacuum. The display tube body is distorted by the extraction, but such a distortion can be corrected by deformations previously applied to the display tube body. Thus, the screen plane can be flattened without the use of any metal band.

Abstract: A flange, which is integrally formed with the inner surface of the cylindrical member, is located at an intermediate point between the end surface position of the cylindrical member to which the electrode plate of one of the discharge electrodes is sealed and the tip position of the discharge electrode portion of that electrode. Both end surfaces of the cylindrical member are hermetically attached with the discharge electrodes. This arrangement prevents inner flashovers without affecting the discharge characteristics of the discharge tube and also ensures manufacture of discharge tubes with no possibility of gas leakage with very high yields even if the machining precision is not so high.
