摘要： In a water-cooled multi-cylinder vertical engine for an outboard engine system, cooling water having passed through an exhaust-manifold cooling water jacket for cooling an exhaust passage within an engine room is supplied to a cylinder-block cooling water jacket provided in a cylinder block through water supply pipes, a branching member and two upper and lower couplings. In this case, the lower coupling is locked below the center of a lowermost cylinder to minimize unevenness in flow rate of the cooling water flowing through a water jacket on opposite left and right sides of a cylinder toward a cooling water outlet provided at an upper portion thereof, thereby making uniform the distribution of the temperature around a combustion chamber, leading to an enhancement in cooling effect.

摘要： An outboard motor has an engine and a mounting case disposed below and connected to the engine. The mounting case has a depression opening upward. The opening is covered by a cover to form a coolant chamber. An exhaust passage passes through the coolant chamber and communicates with an exhaust expansion chamber formed by an extension case to be positioned below the mounting case. The coolant chamber is covered by the cover so that a small mating surface is formed with the coolant chamber independently of an engine mating surface of the mounting case. This simplifies the structure of the mounting case.

摘要： An outboard motor includes a water-cooled V-engine. The engine includes right and left cylinder block portions each having plural cylinders formed therein. The cylinders of each cylinder block portion are vertically juxtaposed. Cylinder heads are disposed behind the cylinder block portions. The outboard motor has horizontal and vertical shafts. The outboard motor can tilt up on the horizontal shaft and pivot sideways on the vertical shaft. The cylinders of each cylinder block portion have a cooling jacket formed therein. The lowermost cylinder has a discharge portion formed at an outermost part thereof. The discharge portion is designed to discharge out cooling water remaining in the cooling jacket.

摘要： An OHC vertical crankshaft engine, comprising: a vertically disposed crankshaft having a first timing pulley at its lower end; a cooling fan attached to an upper end of the crankshaft; a camshaft extending in parallel with the crankshaft at a cylinder head end of the engine and having a second timing pulley at its lower end; and a timing belt passed around the timing pulleys. Thus, the need for lubrication for the transmission mechanism between the crankshaft and the camshaft is substantially eliminated, and the noise generation is reduced. Additionally, since the upper part of the cylinder head is directly exposed to the cooling air produced by a fan provided at an upper end of the crankshaft, a high engine cooling efficiency can be achieved. This effect is even more enhanced if the exhaust port of the engine is disposed above the intake port and extends horizontally and linearly away from the engine.
摘要翻译： 一种OHC立式曲轴发动机，包括：垂直布置的曲轴，其下端具有第一正时皮带轮; 附接到曲轴的上端的冷却风扇; 凸轮轴在发动机的气缸盖端处与曲轴平行地延伸并且在其下端具有第二正时皮带轮; 并且定时皮带绕过定时皮带轮。 因此，基本上消除了对曲轴和凸轮轴之间的传动机构的润滑的需要，并且降低了噪声的产生。 此外，由于气缸盖的上部直接暴露于设置在曲轴的上端的风扇产生的冷却空气，所以能够实现高的发动机冷却效率。 如果发动机的排气口设置在进气口上方并且水平和线性地远离发动机延伸，则这种效果甚至更大。

摘要： An image pickup apparatus having a higher resolution and S/N ratio by use of a line confocal optical system and a photomask defect inspection system using the same. A first spatial filter having a plurality of slits extending in a direction perpendicular to a direction of movement of a sample is arranged in front of a light source and illuminates the sample with lines of light. The transmitted light or reflected light from the sample is received by an image sensor through a second spatial filter having slits substantially the same as the first spatial filter. Each image sensor has light receiving elements arranged in a two-dimensional array and transfers charges stored in the light receiving elements for each line. A charge transfer speed of the image sensors and speed of movement of the sample are linked with each other. The sample is illuminated a plurality of times, the charge produced by each illumination is accumulated, and the cumulative charge is output. By configuring the apparatus in this way, a line confocal optical system is formed, a greater amount of charge is built up by the illumination by the plurality of lines of light, and the S/N ratio is remarkably improved.
