Abstract:
In a click-type applicator, when the propelling element is moved forwards by a clicking operation, the advancing motion is transformed into a rotary motion of a transfer cam element in one direction by the function of guide slots of the propelling element and projected parts so that when a cam portion of transfer cam element meshes with a cam portion at the rear of a rotary cam element, the rotation of the transfer cam element causes rotary cam element to rotate and thereby move the screw shaft and hence a piston forwards. On the other hand, by releasing the clicking operation, propelling element is moved backwards due to the repulsive force of a spring, and the backward motion is transformed into a rotary motion of transfer cam element in the other direction by the function of the guide slots and projected parts so as to restore the original position.

Abstract:
A mold for casting primarily of SMC420, wherein a cavity forming portion comprising maraging steel, which has the toughness and the resistance to heat shock superior to those of SMC420, is provided in a vertical wall heading for a cavity surface from a molten metal inlet and a portion nearest to the molten metal inlet in the cavity surface, which are portions suffering relatively large heat shock in the contact with a molten metal. Also provided is a method for providing the cavity forming portion, which comprises filling a concave portion of the mold with a molten metal prepared by melting a welding rod by arc welding, in other words, carrying out an overlaying welding, and then cooling and solidifying the molten metal.

Abstract:
A direct-feed type writing implement having two ends includes an ink tank and a pair of writing points, arranged at opposite ends of the ink tank. An ink collector is provided for each writing point. An air/liquid exchanger adjusts the internal pressure inside the ink tank by use of capillarity. An ink feeder is provided for each writing point. Each ink feeder includes a center core for feeding ink to the writing point. Air is inhibited from flowing into the ink tank through the ink collector air/liquid exchanger located at one end while the pen is being used for writing at the opposite end.
Abstract:
A clicking-type writing implement includes a writing member having a writing portion at its tip, and a clicking rod for projecting the writing member from a barrel cylinder. When the clicking rod is depressed to engage an engaging portion of a rotor in the barrel cylinder with an engaging surface of a clip cylinder, the writing portion is maintained to project from the barrel cylinder. A cam surface is formed on the inner surface of the barrel cylinder. A cam projection inclined surface which moves and rotates along a cam inclined surface of the barrel cylinder is formed on the rotor to project and retract the writing member. An engaging portion to engage with the engaging surface of the clip cylinder is formed in front of the cam projection inclined surface.
Abstract:

Abstract:
This invention relates to a cured novolak fiber-reinforced, chlorinated rubber molded article having excellent flameproofness, the main components of which are(A) fibers or a fibrous structure containing at least 50 weight % of cured novolak fibers and(B) a rubber composition consisting mainly of chlorinated rubber as a rubber component,the content of said fibers or fibrous structure being 2-80% by weight; and a process for the preparation of said article comprising adhering an organic solvent solution or dispersion of the rubber composition (B) to the fibers or the fibrous structure (A) or impregnating the fibers or fibrous structure with said solution or dispersion, or mixing the fibers with the rubber composition (B), and without any further processing, or during or after the pressing or molding, vulcanizing said chlorinated rubber composition at a temperature of 100.degree.-200.degree. C.
Abstract:
A process for producing a drawn or undrawn flame-resistant and anti-fusing cured phenolic continuous filament which comprises melt-spining an uncured novolak resin which may contain a fiber-forming thermoplastic synthetic resin and then curing the melt-spun filament with a curing agent in the presence of a catalyst; characterized by pre-curing the melt-spun filament with an aldehyde as a curing agent in the presence of an acid catalyst, and then curing the pre-cured filament with an aldehyde in the presence of a basic catalyst.
