An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.

A prosthesis is provided for implantation into a knee joint compartment between a femoral condyle and its corresponding tibial plateau without requiring bone resection. The prosthesis includes a body having a generally elliptical shape in plan and a pair of opposed surfaces where one of the surfaces is generally concave. The body further includes an exterior portion and an interior portion, where the exterior portion is constructed from a higher modulus material than the interior portion such that the body is at least slightly deformable.

The present invention relates to a steering device for facilitating the steering of an implement towed by a work vehicle. The towed implement, for example, a farm implement such as a seeding device, comprises a main frame having front and rear ends and at least one steerable surface engaging wheel attached to the frame. The steering device comprising a sensor means mounted on the main frame of the towed implement for sensing a misalignment of the towed implement and the work vehicle and producing a signal corresponding to the misalignment. The steering device further comprises a steering means associated with the steerable wheel for receiving the signal produced by the sensor means and for effecting movement of the steerable wheel in response to the signal until the towed implement and the work vehicle are once again realigned.

An apparatus for measuring wall thicknesses of objects, comprises: a coordinate measuring machine comprising a probe holder and an object support, the coordinate measuring machine being configured to provide relative movement between the probe holder and the object support in three dimensions; and an ultrasonic test probe which is held by the probe holder. The coordinate measuring machine brings the transducer of the ultrasonic test probe into contact with a position on a surface of an object at the object support so that the probe can measure an object wall thickness at the probe contact position.

Substrates are aligned and then bonded to each other. A substrate bonding apparatus includes a deformer that deforms at least a first one of two substrates that are to be bonded to each other in order to correct misalignment between the two substrates, a holder that holds the deformed first substrate in the deformed state achieved by the deformer, a transporter that transports the holder from a position at which the deformed first substrate is held by the holder while the first substrate remains deformed, and a bonder that bonds the first substrate that has been transported by the transporter to the second substrate. In the above-described substrate bonding apparatus, while the first substrate is not held by the holder, the deformer may deform the holder from a first state to a second state that is more deformed than the first state, and while the first substrate is held by the holder, the deformer may reduce the amount of the deformation of the holder to less than the amount of the deformation of the second state to deform the first substrate.

Low force orthodontic arch wires (100) include a core wire (102) formed of a material having shape memory that extends along a generally curved arch wire axis between a first end (102a) and a second end (102b). The arch wire (100) further includes a plurality of bracket engagement blocks (104) disposed in spaced apart relationship along the length of the core wire (102). Each engagement block (104) is configured for placement within the slot of a corresponding orthodontic bracket with which it works to move the teeth in a desired direction. The engagement blocks (104) are advantageously enlarged relative to the core wire (102), providing for better engagement and reduced play between any given engagement block (104) and its corresponding bracket slot as compared to if the engagement blocks (104) were not present. The engagement blocks (104) may be disposed relative to the core wire (102).

A vehicle system with a charging station and an autonomously movable, electrically powered vehicle dockable therewith, the vehicle system being mutually engageable at an inlet-side on the vehicle and an outlet-side on the charging station arranged to transport energy between the charging station and vehicle when engaged and further being provided with an inlet-side guiding member, an outlet-side guiding member, respectively, arranged to guide the inlet-side and outlet-side engagements from a non-charging position into a charging position upon engaging of the inlet- and outlet-sides when docking the vehicle to the charging station.

A method of fabricating an interconnect structure comprising etching a via into an upper low K dielectric layer and into a hardened portion of a lower low K dielectric layer. The via is defined by a pattern formed in a photoresist layer. The photoresist layer is then stripped, and a trench that circumscribes the via as defined by a hard mask is etched into the upper low K dielectric layer and, simultaneously, the via that was etched into the hardened portion of the lower low K dielectric layer is further etched into the lower low K dielectric layer. The result is a low K dielectric dual damascene structure.

While performing main scanning in which a head having a plurality of nozzles that eject ink is moved in prescribed forward and reverse main scanning directions relative to a print medium, print images are printed on the print medium by forming dots in each pixel aligned in the main scanning direction in accordance with print data. The dot formation position misalignment amount for each nozzle is corrected using image pixel value data indicating the existence of image pixels comprising images and adjustment pixel value data indicating the existence of adjustment pixels in which dots are not formed.

An wafer positioning system comprises a wafer handling chamber with a vacuum sealable opening catching wafers. At least one processing chamber disposed adjacent to the wafer handling chamber has an opening catching wafers, sealed with a gate. A wafer transfer robot with a tray disposed in the wafer handling chamber transports wafers into the processing chambers. A signal receiver is disposed on the front end of the tray. When the tray passes below a wafer, the signal receiver detects wafer position, generating a wafer position signal. A control module receives the wafer position signal through the signal receiver and compares the wafer position signal with a predetermined position signal to correct any misalignment of the wafer.

Disclosed is an image forming apparatus including: an image memory to store image data to form an image with pixels aligned in a main scanning direction and a sub-scanning direction; a print head; and a correction section to perform correction processing on the image data to correct misalignment which occurs when an image is formed, wherein the correction section includes: a memory which can perform burst transfer; a first control section; line buffers; and a second control section, wherein the first control section successively writes the image data in the burst access unit in the memory and reads the image data in the burst access unit while controlling the address of the memory according to a first control signal generated based on previously set information concerning correction; and the second control section selects image data to output according to a second control signal generated based on the information.

A plurality of components (2) are arranged on a plurality of component supplying plates (6). A plate supplying body (50) stores a plurality of the component supplying plates (6) by stacking them. Among supporting guide parts (50b), supporting guide parts forming a pair can be discriminated from those supporting guide parts forming other pairs. An identifying mark part (114) is visibly formed in the plate supplying direction at an edge part of each supporting guide part or in the vicinity in such direction.
