Abstract: There is provided a vertical multicylinder straight engine in which the temperature distribution of a plurality of cylinder barrels is made close to an even state. A cylinder jacket includes: a jacket inlet; a separated channel; a plurality of separated outlets; and heat dissipater channels for dissipating heat of the respective cylinder barrels to engine cooling water introduced through the separated outlets. The plurality of separated outlets include: a front-side separated outlet to a front-end barrel; a rear-side separated outlet to a rear-end barrel; and middle separated outlets to middle barrels between the front-end barrel and the rear-end barrel, and the jacket inlet is disposed so as to be contained within an entire middle barrel side area that is lateral to the middle barrels and has a front-rear length as long as a length from a front-most end to a rear-most end of the middle barrels.

Abstract: An engine is provided where oil is minimally blown off through a breather chamber. The breather chamber includes a plurality of breather inlet chambers each having a breather inlet which opens on a bottom wall; an oil separation chamber where blow-by gases flown out from the breather inlet chambers merge together and oil separation is performed; and a breather outlet. A ceiling wall of each breather inlet chamber is lower than a ceiling wall of an oil separation chamber. It is preferable that the respective breather inlet chambers each have: a remote-side chamber portion disposed remote from the oil separation chamber and a near-side chamber portion disposed near to the oil separation chamber. A ceiling wall of the near-side chamber portion is disposed lower than a ceiling wall of the remote-side chamber portion with a stepped portion formed between the ceiling wall and the ceiling wall.

Abstract: A dental enamel recalcification accelerator that even when used in oral compositions and food or beverage, poses no safety problem, and that is capable of effectively promoting the recalcification of decalcified dental enamel to thereby positively suppress any dental caries; and containing the same, an oral composition and food or beverage. There is provided a dental enamel recalcification accelerator comprising anhydrogalactose-containing red algae and/or an extract thereof as an active ingredient. Further, there are provided an oral composition and food or beverage comprising the dental enamel recalcification accelerator.

Abstract: Light emitted from light-projecting elements constituted by LEDs (light-emitting diodes) or the like is transmitted to a light-projecting optical system of a sensor head portion through an optical fiber cable and projected from the light-projecting optical system onto an object. The light projected onto the object is reflected on the object. The reflected light is made incident on a light-receiving optical system. The light incident on the light-receiving optical system is led to a light-receiving element. The light-receiving element detects the incident light and generates a light-receiving signal based on the quantity of the detected light. The light-receiving signal generated by the light-receiving element is transmitted to a signal processing control portion of a main body portion through a light-receiving circuit and an electric wire cable.
