A driving apparatus of a multi-function machine includes a scanner unit scanning data recorded on a sheet of document and a document transport part to transport the sheet of document. A printer unit prints data on a sheet of paper for an output and includes a carrier including a print head with an ink jet nozzle mounted thereon to carry out the printing operation by moving the print head. The driving apparatus includes a driving motor, a scanner driving part driving the scanner unit, a printer driving part driving the printer unit, and a power switching part disposed with the driving motor, the scanner driving part, and the printer driving part. The power switching part selectively transmits a power of the driving motor to at least one of the scanner driving part and the printer driving part.

A compact, highly accurate and inexpensive brushless motor is disclosed. A bearing is fixed to the inner periphery of a cylindrical portion of a housing, and a shaft is rotatably inserted through the bearing to cover the housing. A yoke arranged at the forward end of the cylindrical portion of the housing is fixed on the shaft. In this configuration, the bearing is arranged at a position on the inside of the yoke, and therefore the motor can be reduced in size to the extent of superposition between the yoke and the housing. The bearing is fixed to one member of the housing, and therefore a high accuracy is realized.

A wiper blade (10) comprising a rubber elastic wiper strip (12) into whose lateral longitudinal grooves resilient rails (18, 20) are inserted as support elements and laterally protrude from the longitudinal grooves, wherein the resilient rails (18, 20) are held together at their ends and are fixed relative to the wiper strip (12) in the longitudinal direction and support a terminal cap (24). It is proposed that the terminal caps (24) have detachable fixing means (34) that engage in a top strip (16) of the wiper strip (12), wherein the axial movability of the resilient rails (18, 20) relative to the wiper strip (24) is limited by the terminal caps.

An image pickup apparatus captures an image from a subject without a focus-adjusting mechanism. An image pickup element has opposed first and second surfaces and an image region formed in the first surface. An optical system causes the image light from the subject to form an image on the image region. A supporting member has a first abutment portion that engages the optical system with nothing sandwiched therebetween, and a second abutment portion that engages the image pickup element with nothing sandwiched therebetween, thereby accurately positioning the optical system relative to the image pickup element. The second abutment portion abuts an area on the first surface except for the image region. A circuit board is fixed to the supporting member and electrically connected to the image pickup element. The circuit board has an opening formed therein such that the image region is exposed through the opening.

A dynamic pressure bearing apparatus has a rotatable shaft to which a hub is mounted, a disk fixed to the hub, a sleeve which supports the rotatable shaft, and a dynamic pressure bearing formed between the rotatable shaft and the sleeve. The rotatable shaft is rotatably supported by the dynamic pressure bearing. The dynamic pressure bearing apparatus is manufactured by integrating the hub and the rotatable shaft by fixing the hub and shaft to each other, processing the disk mounting surface of the hub after integration, such that relative accuracy between the rotatable shaft and the disk mounting surface can be obtained, and then assembling the rotatable shaft to the sleeve.

A variable valve unit for an internal combustion engine includes a first arm opening and closing a valve, a second arm driven by a cam, a third arm receiving a displacement of the second arm to drive the first arm, and a variable mechanism displacing the fulcrum of the second arm. The second arm has a drive plane. The third arm has a shaft member formed with a driven surface contacting with the drive plane. The displacement of the second arm is transmitted to the third arm with sliding between the driven surface and the drive plane.

A wiper coupler adaptor for releasably attaching a wiper assembly to a wiper arm includes a pair of sidewalls, each having recessed sections adapted to operatively engage rails of an attachment member of a wiper arm. An elevated platform is disposed between the sidewalls and a deck to define an aperture adapted to receive a portion of a bent tab of the attachment member, and a snap bridge disposed within the aperture that is adapted to receive a portion of the bent tab of the attachment member to prevent undesired release of the wiper coupler adaptor from the attachment member. A rib is disposed within the aperture and extends from at least one of the sidewalls to prevent the snap bridge from breakage by the bent tab of the attachment member if mis-assembled.

A telescopic actuator is adapted to be used on a right side or a left side of a body. The telescopic actuator includes a housing having a cylindrical shape and formed with an opening portion, an output rod supported inside the housing so as to be protrudable and retractable with respect to the housing, and a stroke sensor comprising a detectable portion provided on the output rod so as to be movable inside the opening portion of the housing and a detecting portion provided on the housing so as to face the detectable portion. A direction in which the detectable portion is eccentrically disposed with respect to a vertical plane including an axial line of the output rod is different depending on whether the telescopic actuator is used on the right side or on the left side of the body.

A method is provided for operating a sliding closure for a metallurgical vessel. The sliding closure includes two tensionable fireproof closure plates opposing one another, with each of the two closure plates being slideably positioned within a corresponding housing part. Spring elements are provided for tensioning the closure plates, wherein one of the closure plates, along with its corresponding housing part, is slideable and can be moved into a closed or open position by a drive member. The method comprises: performing an offline and / or an online diagnosis of an operating condition within an area of the closure plates, by measuring at least one of size, temperature, pressure and force associated with the sliding closure so as to obtain at least one measured value, and evaluating the at least one measured value either directly or together with additional relevant process parameters; and based upon the diagnosis, either continuing use of the sliding closure or discontinuing use of the sliding closure.

A spinning reel spool is detachable from a spool shaft having a tapered surface and an engagement groove. The spool includes a spool unit, an engagement spring, a positioning projection, a lid member, an operation button, and an engagement hole. The spool unit includes a circular mounting space. The positioning projection determines the rotational position of the engagement spring. The operation button is mounted in the lid member and can pass over the engagement groove. The operation button includes a pair of tapered portions that are disposed with the spool shaft therebetween such that the gap between the pair of engagement portions is widened by movement of the operation button in the axial direction. The engagement hole controls the rotational position of the operation button.

A case structure of an integrated package module for a hybrid vehicle is provided. A front case of the integrated package module is formed of a first front case having a receiving groove on a upper portion thereof and a second front case. The case structure can stably mount and support the integrated package module on a vehicle body in a safer and cost-effective manner.
