A drill bit for use in association with a power or hand drill comprising a drill bit head and shaft. The drill bit head includes a drill bit cutting head and a guide point. The drill bit cutting head includes a first and a second cutting vane. Each cutting vane includes a first cutting edge which extends perpendicular to the axis of rotation and is provided for removing workpiece material, a second cutting edge which extends parallel to the axis of rotation and is provided for forming a substantially smooth workpiece bore, and a channel for facilitating the expulsion of removed workpiece material away from the first cutting surface as the drill bit passes through the workpiece.

The present invention achieves an increase in the amount of vapor that is expelled, stabilized fuel injection and improved starting characteristics in a fuel injection pump. In an electromagnetically driven fuel injection pump 20 which allows fuel to escape into the return passage 5 in the initial region of the pressure-feeding stroke of the plunger 21, and which pressure-feeds fuel into the injection port 33 in the later region of the pressure-feeding stroke, pulse powering of the coil 23 that does not lead to the injection of fuel, i.e., pulse powering which is such that the plunger 21 performs a reciprocating motion through the initial region, is performed when the engine 2 is in an idle operating state, or in a state in which the engine 2 is re-started after being stopped immediately following high-load operation. As a result, vapor can be expelled with good efficiency, and the flow rate of the circulated fuel is increased so that the cooling effect is also increased, thus causing the generation of vapor to be suppressed as well, so that the starting characteristics or re-starting characteristics are improved.

The invention relates to a device for expelling liquid from a wiping element which is held on a wiping head of a surface cleaning device so as to form a wiping surface, comprising a container, in which a wiping element holding device accommodating the wiping element as well as a driving device are arranged, wherein the wiping element holding device can be driven by means of the driving device so as to rotate about an axis of rotation. In order to further develop the device in such a manner that it has a lower consumption of energy it is suggested in accordance with the invention that the wiping element holding device form a receiving means, into which the wiping element can be inserted with a surface normal of the wiping surface aligned at an angle to the axis of rotation.

A motorcycle includes an exhaust device connected to an engine unit, and the exhaust device includes: a plurality of first exhaust pipes forwardly extending from an exhaust port which opens in the front of the engine unit; a joint portion for joining the first exhaust pipes; a second exhaust pipe connected to a downstream side of the joint portion and passing below an oil pan disposed in a lower portion of the engine unit; and an exhaust expansion chamber connected to a downstream portion of the second exhaust pipe. A cowling of such a motorcycle includes: a front cowling covering the engine unit and the exhaust device from lower and side portions thereof; and a rear cowling partially covering a rider's seat. The front cowling is formed with an air-exhaust opening at a bottom surface of a rear end thereof positioned to a front lower surface of the exhaust expansion chamber.

A high brightness light emitting diode (LED) includes a base, a reflector cap, LED dices, a plastic layer, a lens, and a silicon rubber layer. Conductive terminals extend from the base for connection with an external power source. The base defines a bore receiving the cap with a bottom of the cap exposed. The cap forms a cavity receiving the LED dices, which are electrically connected to the conductive terminals. The plastic layer comprising PPA, LCP, or engineer plastics is filled in the cavity o with ends of the terminals extending beyond the plastic layer. The lens is positioned over the plastic layer and has projections that snugly fit over and engage the base. The silicon rubber layer is interposed between the lens and the base. With such an arrangement, lights from the LED dices can be mixed twice for enhanced uniformity of brightness of the light distribution.

The inkjet recording head comprises: a first vibrating plate which forms part of a pressure chamber connecting an ink supply port and an ink ejection port; a first actuator which induces ink ejection from the ink ejection port for printing by deforming the first vibrating plate; a second vibrating plate which forms part of the pressure chamber; and a second actuator which induces ink ejection from the ink ejection port for performing maintenance by deforming the second vibrating plate, wherein a relationship K1>K2 is established between a ratio K1 of a volume of ink expelled by deformation of the first vibrating plate in relation to a pressure applied to the first vibrating plate by the first actuator during the ink ejection for printing, and a ratio K2 of a volume of ink expelled by deformation of the second vibrating plate in relation to a pressure applied to the second vibrating plate by the second actuator during the ink ejection for maintenance.

An immiscible liquid separator for maintaining a desired liquid relationship between an oil spillover and a water spillover irrespective of a tilt angle of the separator. The use of the separator is thus well adapted for use on ships and the like. The separator includes a cylindrical weir having an open top over which separated water spills when waste liquid is drained into the separator. The separator also includes a cylindrical oil stack having an open top over which separated oil spills when waste liquid is drained into the separator. The cylindrical oil stack is located within the cylindrical water weir, thus allowing the separator to function as desired independent of the angle of tilt of the separator.

The present invention provides an unvulcanized rubber member for tire manufacturing. The member forms at least a portion of a green tire, and features: multiple rib-protrusions that extend in a direction corresponding to a circumferential direction of the tire, and multiple grooves that extend in a direction corresponding to a radial direction of the tire and intersect the rib-protrusions. In accordance with the present invention, during vulcanization of the tire, the unvulcanized rubber member for tire manufacturing can efficiently expel air at the interior of the unvulcanized tire and between the unvulcanized tire and a vulcanizing mold.
