摘要： A keyless chuck for a rotary tool comprises a chuck body which is adapted to be coupled at its one end to a drive spindle of a drive source and coupled at the other end to a tool bit for establishing a driving connection from the drive source to the tool bit. Relatively rotatable to the chuck body is a sleeve ring which is operatively connected to a set of gripping jaws for tightening the gripping jaws on the tool bit upon being rotated in one direction and loosening the same upon being rotated in the opposite direction. A one-way clutch is provided to rotatively fix the sleeve ring to the chuck body when the chuck body is driven to rotate in the direction of turning the tool bit reversely. A handle ring is disposed around the sleeve ring to be rotatable relative thereto within a limited extent such that it disengages said one-way clutch when said handle ring is rotated in one direction within said limited extent relative to said chuck body, allowing said chuck body to rotate freely from said sleeve ring to loosen said gripping jaws.

摘要： There is disclosed an electric blower assembly provided with an air guide structure designed such that the current of air expelled from a rotating impeller under the influence of centrifugal force is guided to the body of an electric motor while being accelerated. The air guide structure comprises an air guide block having front and rear compartments. The front compartment includes a plurality of volute chambers designed such that, during flow of air within the volute chambers, the dynamic pressure can be converted into static pressure. The flow of air under the static pressure is subsequently guided at a relatively low pneumatic velocity into the rear compartment and then into the body of the motor to cool the latter. The air used to cool the motor is thereafter exhausted to the outside of the motor.

摘要： A depth adjuster for a rotary tool such as a screwdriver having a tool bit projecting through a nose provided at the front end of the rotary tool. The depth adjustor comprises a locator sleeve mounted on the nose to project on the front end of the tool in such a manner as to surround the tool bit. The locator sleeve has an internal thread engaged with an external thread on the nose so as to be axially movable relative to the nose and the tool bit as the sleeve rotates about the nose. A lock ring is fitted on the nose to be rotatively fixed but axially movable relative thereto. The lock ring is biased towards the locator sleeve by a spring for locking engagement into the locator sleeve so as to rotatively fix the locator sleeve around the nose, whereby retaining the locator sleeve at a desired axial position relative to the nose. The engagement between the lock ring and the sleeve is such that, when the locator sleeve is forced to rotate about the nose, the lock ring moves axially rearwardly against the spring bias to disengage the locator sleeve from the lock ring, thereby permitting the locator sleeve to rotate freely from the lock ring for adjustment of an axial position of the sleeve relative to the nose. The spring is supported between the lock ring and a rear end of the locator sleeve so that the spring is received and concealed within the locator sleeve together with the lock ring.

摘要： An apparatus for effecting forced circulations of two separate fluids through separate fluids paths provided therein and, simultaneously, heat-exchanging between the fluids in a single unit is disclosed. It includes an impeller having a concentric corrugated zone made of a thin sheet material of good heat-conducting property, supported by a central disk member and an annular peripheral member, along both side of which flows of separate fluids are created, when the impeller is rotated. The heat-exchanging between the fluids each having a temperature difference with respect to the other is performed through the corrugated zone which the fluids are propelled through said paths.
