Abstract: A cigarette holder having an attractive appearance and a compact structure suitable for use by ladies without any feel of reluctance, and capable of effectively removing nicotine and tar while permitting a visual check of the state of removal of nicotine and tar from the outside. A nicotine extractor made of a colored material, for removing the nicotine and tar by impact caused by collision of smoke, is fitted in a cigarette holder body made of a transparent material. When the colored nicotine extractor has become invisible from the outside of the cigarette holder body due to accumulation of nicotine and tars, the cigarette is no longer usable and can be discarded.

Abstract: An annular tank for storing nuclear reaction material in an annular space formed among seamless upper and lower annular dies disposed elevationally in a predetermined space and inner and outer sheaths extended on the inner and outer peripheral surfaces of the upper and lower dies. The tank avoids thermal strain and deformation by forming the upper and lower dies in a seamless manner to thus enhance the heat dissipating effect together with high working accuracy and strength. The method of fabricating the annular tank is simple by omitting the use of jigs for welding the segments with less loss and high production yield.

Abstract: A sealed beam lamp assembly, suitable for use as a motor vehicle headlight, has an incandescent lamp mounted within an inert-gas-filled, molded-glass housing integrally comprising a reflector and a control-lens cover. For supporting the lamp in position within the housing, a metal-made support rod extends forwardly from one of ferrules on the reflector and has its front end preformed into the shape of a U to provide a rearwardly directed fold. Welded to this fold of the support rod is a metal band rigidly encircling the base of the lamp. The lamp position relative to the reflector is therefore adjustable as required by manually turning the fold of the support rod about its main straight portion. The support rod serves also to provide electrical connection between the ferrule and one of the lamp leads.

Abstract: For replenishing a plating bath with copper or other metal to be electrodeposited with the use of an insoluble anode, scrap metal such as copper wires is received in a makeup tank, into which are passed the gases generated within the plating tank with the progress of electroplating operation. The plating solution in the plating tank is also directed into the makeup tank and sprayed on the scrap copper wires, thereby dissolving same. The dissolved copper is then filtered, heated, and introduced into the plating tank.

Abstract: Apparatus for the production of metal foil or printed circuit patterns on a continuously advancing strip of electrically conductive material includes a cathode under which the conductive strip is fed in sliding contact therewith. An insoluble anode is disposed under the cathode, with an interelectrode gap between the anode and the cathodic conductive strip traveling under the cathode. Lying next to one end of the anode is a solution inlet block defining a solution inlet from which the electroplating solution containing the metal to be deposited is fed turbulently into the interelectrode gap to cause the electrodeposition of the metal on the downward-facing surface of the conductive strip. A shield block of electrically insulating material is mounted over the solution inlet block for shielding the conductive strip traveling thereover from premature metal deposition due to leaking current and hence for avoiding the development of pinholes in the metal foil or circuit patterns.

Abstract: This invention relates to a method of bridge erection i.e., an arrangement for erecting a bridge girder. More particularly, it is concerned with an erection method, in which a bridge girder is smoothly extruded, together with a movable member, on a temporary support member which is disposed on an upper shoe until the girder reaches a position near the installation position, whereupon a coupling member for connecting the upper shoe with a sole plate which is pre-fixed to the girder, is attached to the sole plate, then in this condition the girder is again moved forward up to the installation position while pushing the end portion of the temporary support member on the upper shoe by the coupling member so as to displace the temporary support member and the movable member by the coupling member, whereby the bridge girder and the support structure are fixed in engagement with each other without the need to lift the bridge girder.

The hinge mounting plate thus constructed further comprises a longitudinal and lateral control plate superimposed on the surface of the control plate and perforated with a long hole for guiding the control plate, and a lateral control screw pivotally securing both the rear side ends of the longitudinal and lateral control plate and the hinge supporting arm at the front side end of the control plate.

Abstract: A linear ball bearing unit made of a linear ball bearing and an elongated track shaft as well as a method for manufacturing the bearing unit. The linear ball bearing consists of balls, a half-split bearing case, which in turn is formed by splitting an elongated square bar presenting a plurality of guide grooves for the balls along diametrically opposing two grooves, and a half-split ball retainer also presenting a plurality of guide grooves of the balls. The elongated track shaft is assembled with said linear ball bearing. The line passing through a first point of contact between a loaded ball and its corresponding R-groove in the track shaft and a second point of contact between the same loaded ball and its corresponding R-groove in the bearing case meets a horizontal line at an acute angle.

Abstract: An unlimited sliding ball spline assembly, i.e., a ball spline assembly, has through holes for non-loaded balls formed in an outer sleeve on the extensions of lines connecting loaded balls, spline shaft bearing surfaces for loaded balls and the non-loaded balls. Its contact angle is rendered as close as possible to the direction of torque to make the torque transfer greater. Each of the through holes for the non-loaded balls are axially spaced from its adjacent through holes a distance which is required for allowing the balls to change their travelling direction. The outer sleeve has grooves in its inside wall surface. On the side walls of the grooves is formed an axially-extending curved bearing surface for loaded balls. A ball holder with slits is located within the outer sleeve which prevents loaded balls travelling on the bearing surfaces of the outer sleeve from falling down. Tongues are disposed at each end of each of the slits.
