An apparatus and method for determining an inclination angle θ between an axis of an elongate object such as a cane, a pointer or a jotting implement such as a pen, pencil, stylus or the like and a normal to a plane surface at times when a tip of the elongate object is contacting that plane surface. The apparatus has an emitter mounted on the object for illuminating the plane surface with a probe radiation at an angle σ with respect to the axis of the object. The apparatus also has a detector mounted on the elongate object for detecting a radiation characteristic of a scattered portion of the probe radiation returning from the plane surface and a computing unit for deriving the inclination angle θ from the radiation characteristic. A scanning arrangement, such as a uniaxial or biaxial scanner, or a light guiding optic can be used for varying angle σ, and the probe radiation can be emitted in the form of a scan beam. Preferably, the emitter and detector of the scattered portion of the probe radiation are integrated and the scattered portion of the probe radiation whose characteristic is being measured is the back-scattered portion. The radiation characteristic detected by the detector can be the intensity, polarization, time-of-flight or any combination thereof.

A thin film transistor structure in which a source electrode and a drain electrode formed from a metal material are in direct contact with an oxide semiconductor film may lead to high contact resistance. One cause of high contact resistance is that a Schottky junction is formed at a contact plane between the source and drain electrodes and the oxide semiconductor film. An oxygen-deficient oxide semiconductor layer which includes crystal grains with a size of 1 nm to 10 nm and has a higher carrier concentration than the oxide semiconductor film serving as a channel formation region is provided between the oxide semiconductor film and the source and drain electrodes.

A knife-edge conditioning apparatus comprises at least one precision angled knife guide with one face of the knife blade maintained in sustained sliding or rolling contact and which guides the elongated edge of the blade into sustained contact with the hardened surface of an object and positions the plane of the adjacent edge facet at a precise predetermined angle relative to the contact plane of the hardened surface made of a material of equal or greater hardness than the metal of the knife blade without any tendency to abrade as the blade face is moved along the guide with its elongated edge in sustained contact with the hardened surface.

The present invention discloses a rotating shaft structure with automatic locking mechanism, characterized in which a shaft extending axially from an axial member passes through, in sequence, the core hole of the upright frame plane of the main frame, a friction disc, a disc-like connecting part connected with the frame plane, a cam member comprising a fastening part and a sliding part, at least an elastic body, and a connecting segment on the free end of the shaft connected with a end enclosure so as to form axial pressure to constrain the elements described above. The shaft and the main frame are provided with a linking portion and a connecting portion, respectively. The outer and inner edges of the adjoining planes between the fastening part and the sliding part are provided with at least a wedge block and at least a wedge slot alternately so as to connect the fastening part and the sliding part together. Consequently, when the axial member rotates, the inclined plane of the wedge slot of the sliding part moves upward along the inclined plane of the wedge block and thus axially presses the elastic body so as to prompt the contact plane of the sliding part to rotate along the wedge blocks of the fastening part. When the axial member rotates reversely, the wedge slots of the sliding part move to the wedge blocks of the fastening part and, under the extending action of the elastic body, the wedge slots are engaged into the wedge blocks so as to form an automatic locking of butting joint.

A device includes a plane metallization layer, and a plane plated through hole attached to the plane metallization layer and terminating at the at a major exterior surface with a plurality of component mounting pads. The plated through hole is attached to the plane metallization layer. The plane plated through hole is electrically isolated from the plurality of component mounting pads at the exterior surface. A method for testing the device includes contacting the signal carrying through hole, and contacting the plane through hole, and checking for current flow between the signal carrying through hole and the plane through hole. If current flows between the signal carrying through hole and the plane through hole the device fails. If no current flows between the signal carrying through hole and the plane through hole the device passes.
