An electric power tool incorporating a single fan that provides efficient cooling of the motor and transmission while reducing the cost and size of the power tool. The power tool includes a speed reduction transmission provided within a housing between the motor and a chuck which is located at the front end of the power tool. The rotation of the fan cools the motor and the transmission by drawing in external air from intake ports formed in the housing, and collectively exhausts the warmed cooling air through exhaust ports formed in the housing. The power tool includes a fan, located between the motor and the transmission, that is constructed to draw in two separate streams of cooling air from air intake ports located adjacent to the motor and the transmission, and to exhaust used cooling air through exhaust ports located adjacent to the fan.

A semiconductor device and a manufacturing method thereof are provided. The fin semiconductor device includes a fin formed on a substrate and an insulating material layer formed on the substrate and surrounding the fin. The fin has a semiconductor layer that has a source region portion and a drain region portion. The fin includes a first channel control region, a second channel control region, and a channel region between the two channel control regions, all of which are positioned between the source region portion and the drain region portion. The two channel control regions may have the same conductivity type, different from the channel region.

A power unit for a motorcycle having a continuously variable transmission, which is housed in a transmission chamber inside a engine body and which accomplishes stepless changes in the transmission of power from a drive pulley shaft to a driven pulley shaft by changing the effective diameter with which a belt actually wraps around each of the drive and the driven pulleys. An input clutch is set between a crankshaft and a drive pulley and is provided on the drive pulley shaft. A starter clutch is set between a driven pulley shaft and a rear wheel and is provided on the driven pulley shaft. The switching between the engagement and disengagement of one of the input clutch and the starter clutch is hydraulically controlled. Meanwhile, the switching between the engagement and disengagement of the other one of the input clutch and the starter clutch is mechanically controlled.

The inventions herein relate generally to improvements in photogrammetry and devices suitable for obtaining such improvements. Some embodiments use only a single passive image-capture device to obtain overlapping 2D images, where such images at least partially overlap with regard to at least one object of interest in a scene. Such images can be processed using methods incorporating structure from motion algorithms. Accurate 3D digital representations of the at least one object of interest can be obtained. Substantially accurate measurements and other useful information regarding the at least one object of interest are obtainable from the methodology herein.

A fundus optical image device includes a light source, a first optical element set and a second optical element set. The light emitted from the light source reaches the fundus through the first optical element set. The second optical element set has at least one curvature-adjustable lens. The light emitted from the light source is reflected by the fundus and then passes through the curvature-adjustable lens to present an image of the fundus.

An operating member including an actuating part movably mounted between a rest position and a switching position, a circuit board with an open contacting portion, a switching mat made of an elastic material disposed adjacent to the circuit board, and at least one contact pill formed on a side of the switching mat facing towards the circuit board, which cooperate in such a way that, in the switching position of the actuating part at the latest, the open contacting portion of the circuit board is closed by the contact pill, and where the switching mat moreover forms at least one tactile-feel dome which is associated with the contact pill, is elastically compressible by actuation of the actuating part in the direction of the switching position and which, in its initial position, defines a unilaterally open hollow volume in the switching mat, in order to cause a tactile feedback on the actuating part, where the contact pill is disposed outside the hollow volume defined by the tactile-feel dome.

The present invention provides a silicone composition that includes an epoxy-functional organopolysiloxane resin and an epoxy-functional organosiloxane oligomer, and a method of preparing optical waveguides using the silicon composition. The present invention also provides a cured silicon composition, and an optical waveguide that includes the cured silicon composition.

A vibration exciter, particularly for a vibration pile driver, includes at least four shafts disposed parallel to one another, on which two outer imbalance masses are disposed, in each instance, between which a central imbalance mass is positioned. The central imbalance mass is mounted on the shaft so as to rotate relative to the outer imbalance masses, in each instance. The imbalance masses of the at least four shafts are combined into two imbalance groups, the imbalance masses of which are all synchronized with one another in torsionally rigid manner, in each instance, wherein not only outer imbalance masses but also inner imbalance masses are provided in each of the two imbalance groups, and wherein a phase shifter is provided, by way of which the phasing of the two imbalance groups relative to one another can be adjusted.
