Abstract: An image-forming machine equipped with a transfer device of the type not using a transfer corona discharger is disclosed. A charge supply member is disposed opposite to an image forming member on whose surface a toner image is to be formed, and at a greater distance than the thickness of a transfer material from the image forming member. A voltage of a predetermined polarity is applied to the charge supply member. In a transfer zone, the surface of the transfer material is brought into contact with the surface of the image forming member, while the back of the transfer material is not contacted with the surface of the charge supply member.

Abstract: A galvannealed steel sheet having a superior spot weldability characteristic in which the steel sheet has a base steel sheet cold-rolled from a material containing 0.005 wt % or less of C, 0.005 to 0.05 wt % of Ti, 0.01 to 0.1 wt % of Al, 0.005 to 0.015 wt % of Nb and 0.0002 to 0.002 wt % of B. In the process for making, the hot-dip plating layer applied after the alloying heat treatment has an Fe content of from 9 wt % to 12 wt %.

Abstract: In a split bobbin designed to be rotatably mountable on a core and attached to a bobbin holding base after specific winding of coils, the split bobbin has collars at least at its both ends and cutout sections at least at two places in the outer periphery of these collars. In these cutout sections are provided lead terminal holding holes of specific depth in which rod-like lead terminals can be inserted.

Abstract: In lap joint welding of galvanized sheets, the occurence of blowhole and pit is prevented by applying a blowhole.multidot.pit preventing agent comprising a phosphorus compound as an effective ingredient prior to the arc-welding.

Abstract: A picture tube sealing apparatus for thermally welding a stem structure and a neck portion of a glass bulb thereof to each other and thereby seal the same. A table, on which a plurality of burners formed correspondingly to the diameters of the neck portions of various types of glass bulbs are arranged unitarily so that the burners have a predetermined angle with respect to each other, is turned to move a burners corresponding to the diameter of an object glass bulb to a predetermined position to thereby carry out a burner-switching operation, whereby the heating power of the burner can be regulated without manual operation even when the neck portions of glass bulbs fed sequentially have a plurality of different diameters.

Abstract: There is disclosed a method of installing a mount assembly in a cathode ray tube wherein convergence characteristics are enhanced by properly setting levels of tube of a color cathode ray tube and of an electron gun. When a neck portion of the tube and a stem structure mounted with the electron gun are sealed to each other by heating, a distance between a standard level of the tube and that of the electron gun is measured. Comparison/arithmetic processing is effected both on the thus measured value and on a previously stored standard distance to seek a difference between the two values. The tube body or the electron gun is controlled by a moving operation so that the difference falls within an allowable value. After this, the sealing process is carried out.

Abstract: When producing a picture tube, the reference axis of a phosphor screen in the horizontal direction and an in-line horizontal axis of the aperture center of an in-line type electron gun can be aligned highly accurately during a sealing work and picture tubes providing high quality can be obtained with high productivity by use of an apparatus for producing a picture tube which comprises(i) first detection means for detecting a predetermined axis, such as a horizontal axis, of the phosphor screen inside a glass bulb fitted to a bulb holder,(ii) second detection means for detecting a second predetermined axis, such as an in-line horizontal axis of the aperture center, of an in-line type electron gun fitted to a stem mounted on a mount pin, corresponding to the predetermined axis of said phosphor screen;(iii) a calculation circuit for calculating the detection signal by the first detection means and the detection signal by the second detection means and outputting a "same" or "not same" signal;(iv) a sealing machi

Abstract: There is disclosed a sealing apparatus for picture tubes which includes a heater unit. This heater unit is located outside an index table, having bulb holders for retaining the glass bulb, during rotation of the table and is moved onto the table during a halt of the rotation. A bulb neck portion is encompassed with the heater unit to be heated by this unit. In this sealing apparatus for picture tubes, it is feasible to rapidly heat process the bulb neck portion without undergoing influences of external disturbances, whereby sealing of high quality can be obtained.

Abstract: An austenitic stainless steel welded metal layer having the given composition containing delta-ferrite phase is previously overlay welded as an intermediate layer prior to overlay welding of a surface layer of stainless steel, nickel alloy or the like on a base metal of carbon steel or low alloy steel. In the said composition, by making the ratio of Creq/Nieq to be more than 1.85, the disbonding is prevented and by making Creq to be less than 26% and the content of delta-ferrite phase to be less than 20%, the deterioration of flexural elongation is prevented. The present invention is applicable to the lining on an inner surface of a chemical reactor vessel, such as a desulfurizing reactor for petroleum-refining to be used under a high-temperature, high-pressure hydrogen environment.

Abstract: A coil unit formed of a coil-wound inner core partially circumferentially encased by an outer core. The coil unit is mounted on a plate with the outer core externally exposed and covering the lead-in wires to the coil which are adhered to contacts on the plate.

Abstract: A coil element formed from a drum-shaped ferrite core on which a coil is wound, magnetic members each made of a magnetic and electrically conductive metal and formed so as to fit to the outer surface of the drum-shaped ferrite core and spaced from each other so as to be electrically insulated from each other, and connection terminals forming a part of the magnetic members connected to the ends of the coil.

Abstract: Impaired hearing is treated by administering to a human suffering from impaired hearing Coenzyme Q of the general formula: ##STR1## wherein n is 7 to 10.
