A pointer comprises an attached portion and a main body. The attached portion is attached to an instrument. The main body is fixed to the attached portion at a basic portion thereof and extending toward a free portion thereof. The main body has a reflective surface and a foil-stamping layer. The reflective surface is formed at an inclined surface of the basic portion and inclined to a traveling direction of light entering the main body. The foil-stamping layer is formed on a bottom surface of the main body and diffusely reflects light reflected by the reflective surface. The reflective surface is curved like a collective convex lens in a transverse direction of the inclined surface and a diffusive concave lens in a vertical direction of the inclined surface.

Plural first exhaust pipes are disposed as exhaust paths at an upper portion of a heat treatment apparatus. Exhaust gases are discharged from the inside of the heat treatment apparatus to the respective exhaust pipes. Inlets of catalyst units are connected to outlets of the first exhaust pipes, and second exhaust pipes are connected to outlets of the catalyst units. Exhaust gases are discharged from exhaust ports of the second exhaust pipes to the outside (e.g., the atmosphere) of the heat treatment apparatus.

A polyarylene sulfide resin composition has an excellent moldability to produce moldings excellent in mechanical properties without corroding or staining metal parts such as molds during molding, and comprises 100 parts by weight of a polyarylene sulfide resin (A) and 0.05 to 3 parts by weight of zinc oxide whiskers (B).

A trioxane polymer is continuously produced with a continuous stirring-mixing apparatus. The apparatus includes two mutually parallel rotational shafts, a large number of paddles mounted on each rotational shaft and a barrel having an inside wall surface along the circular surface traced by the respective paddles, as they rotate. Thus, the barrel has a cross-section in the shape of two circles concentric with the two rotational shafts, which overlap each other. The apparatus is also provided with a temperature controlling jacket. In the operation of the apparatus, a material mixture of trioxane, catalyzer, other copolymerizable comonomers, as the case may be, and additives, is continuously fed in through a material supply port located at one end thereof, then, the material mixture is subjected to polymerization or copolymerization reaction, while being stirred by turning the aforementioned rotational shafts in an opposite direction to each other and, thereafter, the polymers or copolymers of trioxane are taken out as fine granules through a discharge port located at the other end thereof. The method is characterized in that at least one set of paddles of a sectional shape which meets a requirement that when a pair of paddles facing each other are turned in different directions around their rotational axes, the clearance between them shall be kept always as narrow as less than 3/100 of the barrel ID, are mounted on each shaft, adjoining each other, and the different direction turning is made in a state such that the clearance between the farthest part from the rotational axis of said paddle and the inside wall of the barrel are always maintained as narrow as less than 3/100 of the barrel ID.

A solid polymerization product is continuously produced from a liquid stock by employing a continuous agitator-mixer type reactor including two parallel shafts rotatable in same direction or in opposite directions, a multiplicity of paddles mounted on each of the shafts, and a barrel with its inner periphery proximate to the outer peripheries of the paddles, said paddles being arranged so that the major axis end of each paddle on one of the shafts is allowed to periodically come close to the minor axis ends of a corresponding paddle on the other shaft, said reactor being such that feed stock is charged from an inlet port provided at one end of the longitudinal of the reactor and polymerization product is discharged from an outlet port provided at the other end, said method of continuous polymerization being characterized in that the rear-side portion of the reactor including the outlet port is raised so that the major axis of the reactor has a slope angle of 1.degree.-10.degree. relative to the horizontal, whereby reaction is allowed to take place in the reactor as installed in such inclined state.
