Disclosed is an extraction method for optical character recognition systems in which the necessary character features for recognition process are extracted from a character information detected and digitized by an optical scanner. In accordance with this method, the local features of every adjacent two rows or columns of a digitized character pattern on a two-dimensional plane are extracted row by row or column by column and are successively integrated so as to extract in a global manner the respective feature types such as concavity and convexity, loop and connectivity of the character pattern. At the same time, the global feature regions or segments are separated and each of the separated feature segments is coded without any loss of the information. The feature quantity of each segment is obtained on the basis of the coded representation. Any local concavity or convexity noises are eliminated simultaneously with the extraction of the global features.

A glass run is provided with extruded portions and a molded portion. The extruded portions and molded portion each have an extension portion provided in the base portion so as to extend and contract in a direction toward the inside and outside of a vehicle. The extension portion is provided at a position which deviates from a position of the base portion which constitutes a section defined as extending from a position which intersects with an extension along an interior side of the door window glass to a position which intersects with an extension along an exterior side of the door window glass and to which an end face of the door window glass is opposed.

A Geneva drive mechanism includes a Geneva gear having arcuate recesses and radially outwardly opening slots arranged alternately in a circumferential direction thereof, and a driving member having an engaging element for engaging the slots. The driving member has a cam. The cam includes a plurality of rolling elements rotatable and movable circumferentially of the driving member. The rolling elements are arranged in a portion of the cam which contacts the arcuate surfaces when the engaging element is disengaged from the slots and rotation of the Geneva gear is restricted.

A model for a previously defined form is provided in terms of directional features for particular evaluation points and shift vectors from one evaluation point to the next. An input image is represented by density gradients for different directional planes. Shift operations for a counter plane which is used to accumulate values for evaluating the similarity between the image and the model, and add operations in which values from input directional planes as specified by the model are added to the counter plane, are performed repeatedly by parallel processing to find the total match with the model for the form.

An intermittent transmission apparatus according to this invention, broadly, includes a driving element and a driven element. The driving element comprises a first cam having a first cam surface, a second cam having a second cam surface, and an intermediate member displaced between the first and second cams. The driven element comprises a driven element main body having recesses for contacting a plurality of rollers arranged on the intermediate member, bearings erected on the driven element main body to be pushed by the first cam surface, and bearings erected under the driven element main body to be pushed by the second cam surface. During non-drive period of the driven element, the bearings contact a circular arc surface of the second cam, and further the recesses contact the plurality of rollers, to restrict rotation of the driven element.

In a computer-aided design (CAD) method for the intra-chip wiring in a hierarchical implementation design of a semiconductor integrated circuit, wiring pattern spaces from block edge terminals are guaranteed while preventing any wiring detour in inter-block nets. Logical line connecting information and implementation information such as contours of parts and terminal positions are inputted from a logical file and a library to extract block edge terminals so as to define a block boundary in accordance with layout positions of parts to be allocated. On the block boundary defined, one virtual terminal is generated for each block edge terminal to dispose wirings between the block edge terminals and the associated virtual terminals. An intra-block net wiring is then achieved without a short circuit to the wirings between the block edge terminals and the associated virtual terminals. Finally, the virtual terminals and the wiring pattern between the block edge terminals and the associated virtual terminals are deleted.

An intermittent transmission mechanism that includes a driving rotating body adapted to rotate around an input shaft and a driven rotating body adapted to rotate around an output shaft is disclosed. The driven rotating body has arcuate recesses and a gear. The driving rotating body has a partial gear adapted to mesh with the gear of the driven rotating body to drivingly rotate the driven rotating body at predetermined angles in an intermittent manner, and a cam portion provided with a rotation restricting surface which moves relatively along arcuate surfaces of the arcuate recesses. Provided around the cam portion of the driving rotating body are guide grooves for guiding rolling elements in contact with the arcuate recesses of the driven rotating body. The partial gear and the cam portion on the driving rotating body are displaced along the axis of rotation, and the gear and the recesses on the driven rotating body are displaced along the axis of rotation.

In designing wiring for semiconductor integrated circuits, wiring channels are assigned to reduce a signal delay time developed parallel traces. The selection of the wiring channels for all of the wiring oriented nets of the circuits is based on the trunk trace length between the terminals. For the longer trunk trace lengths, a double-pitch wiring channel is assigned. First, the determined trunk-trace lengths are sorted in decreasing order of length. Then, a double-pitch wiring channel is assigned for the trunk-trace lengths that are greater than a predetermined length. When no double pitch channels remain, single pitch channels are used.
