Abstract: In a double facer in which a one-sided corrugated board and a liner sheet which are web-like and which are superposed with each other are glued to each other while they travels on a heating plate so as to produce a corrugated board, the heating plate has a thin wall thickness so as to enhance the efficiency of heat transfer to a paper sheet which travels on the upper surface of the heating plate, and the heating plate 20 is provided at the lower surface thereof with a heat radiation means (having the configuration that reinforcing ribs 22 are formed at the lower surface of the heating plate in a direction orthogonal to the direction of travel of a paper sheet, having their height which are successively decreased, or several steam through-holes 51 are formed in the heating plate, and are adapted to be fed therein with saturated steam whose pressure or temperature is successively lowered) in order to decrease a temperature difference between the upper surface and the lower surface of the heating plate so as to

Abstract: Information of a specimen holder or information of a specimen mounted on the specimen holder is stored in a memory inside the specimen holder mounted to an electron microscope. The memory is accessed to transmit the information of the specimen holder to the electron microscope, thereby ensuring that the user can use the specimen holder without mistaking characteristics of the specimen holder and danger of erroneous recording of the specimen information can be reduced.

Abstract: A carburetor has a throttle valve assembly with a cam member and cam surface internally arranged in a body of the carburetor. The cam member is carried by the throttle valve body and preferably has outwardly extending tabs for locking engagement within slots formed in the throttle valve body. The throttle valve body has a dust seal constructed from an elastomeric material. The dust seal has one end sized for a tight resilient fit about a boss extending upwardly from a cap of the carburetor, and another end sized for tight resilient fit about a shaft carried by the throttle valve body, and a mid-section expanded over a flange.

Abstract: A tack label difficult to peel from a container in a processing environment with normal temperature water and easy to peel from the container in a processing environment with hot water and a plastic container. The tack label according to this invention includes a label base material, a printing layer formed on one surface of this label base material, and an adhesive layer formed on the surface of the other of a label base material. The adhesive layer comprises an adhesive that is difficult to dissolve under an environment with normal temperature water and easy to dissolve under a processing environment with hot water. The result is a tack label that is difficult to peel from the container in a washing process, but easy to peel in a regenerating process.

Abstract: The present invention relates to 1-arylpyrimidine derivatives represented by general formula (I): ##STR1## wherein R.sub.1 is H, alkyl or aralkyl;Ar is 1-naphthyl, or a substituted or unsubstituted phenyl group;R.sub.4 is a substituted phenyl, a substituted styryl, 1-methylcyclohexyl, 4-methylcyclohexyl, 4-oxo-4H-pyran-2-yl or 2-oxo-2H-pyran-5-yl group;R.sub.5 and R.sub.6 are each independently H or alkyl;R.sub.3 is H, and R.sub.7 and R.sub.8 are combined together to be oxo, or else R.sub.3 and R.sub.7 are combined together to be another direct bond, and R.sub.5 and R.sub.8 are combined together to be a direct bond,or pharmaceutically acceptable salts thereof; and methods for treating allergic diseases with such compounds.

Abstract: A valve guide member for internal combustion engines is formed of an Fe-based sintered alloy having excellent wear and abrasion resistance, consisting essentially, by weight %, of 1 to 4% C, 1.5 to 6% Cu, 0.1 to 0.8% P, and if required 0.05 to 1% Mo, and the balance of Fe and inevitable impurities, the Fe-based sintered alloy having a structure having a matrix formed mainly of pearlite, in which are dispersed hard Fe--C--P compounds and free graphite, or alternatively hard Fe--C--P compounds, carbides, and free graphite when the alloy contains Mo, the free graphite including 0.5 to 10 area % coarse free graphite having a particle diameter of 70 to 500 .mu.m.

Abstract: An optical information reproducing apparatus wherein a light spot is projected on a rotary disc on which information is recorded, thereby to reproduce the information recorded on the disc, is provided with detection means to detect an amount of eccentricity of the disc by counting a number of tracks on the disc which the light spot at rest traverses when the disc is rotated by one revolution, and eccentricity correction signal generation means to generate a sinusoidal wave signal whose amplitude is determined by the detected amount of eccentricity and whose period is determined by a rotational period of the disc.The position of the light spot is controlled in accordance with the sinusoidal wave signal and a tracking control signal.
