Abstract: A torque detection device includes a first yoke and a first magnetic guide member. A first opposing portion of the first magnetic guide member overlaps with a first-yoke ring of the first yoke when the first-yoke ring is projected onto the first opposing portion in an axial direction. Furthermore, the first opposing portion overlaps with an inner surface of a second tubular portion when the inner surface is projected onto the first opposing portion in the axial direction. A housing distance, which is a shortest distance measured from the first opposing portion to the inner surface, is longer than a yoke distance, which is a shortest distance measured from the first opposing portion to the first-yoke ring.

Abstract: According to an embodiment, a pattern dimension calculation method includes setting a reference point on a first circuit pattern, calculating, as a size of area of an opposing pattern, a size of area of a range corresponding to the reference point of a second circuit pattern opposite to the reference point, and calculating a dimension of the first circuit pattern in accordance with the size of area of the opposing pattern.

Abstract: An insertion portion includes a holding member that holds an observation portion, and a tubular bending portion. A small-diameter portion of the holding member is fitted into an inside surface of a distal end side portion of the bending portion. A hole portion is provided in the bending portion. A concave portion is provided at the small-diameter portion. A screw member penetrates the hole portion by screw-fastening, and a distal end side thereof is housed in the concave portion. A diameter of the concave portion is larger than an outside diameter of the screw member. A length obtained by adding a depth of the concave portion and a thickness of the distal end side portion of the bending portion is greater than an axial direction length of the screw member. The screw member is held in a non-contacting state with respect to the concave portion in the hole portion.

Abstract: A data compression system enables user-level applications to compress and decompress files to save storage space even for user-level applications that are not modified to use compressed files. User preferences associated with a user terminal are established for the compression of data, e.g. video data, wherein the user preferences comprise selective enablement of compression for at least one file type. An exemplary system determines the type of a digital data file, e.g. a digital video data file, being output from an application or input to an application, and performs transparent file-type-based compression or decompression of the digital data file, if enabled by the established user preferences. Files of the selected file types are stored with compressed formats and may even have different names, but are shown to user-level applications to have the same file names and file sizes as original uncompressed files. Therefore, the existing applications can perform operations without any disruptions.

Abstract: A fast loss less image compression system based on neighborhood comparisons compares pixel value differences with neighboring pixels and replaces such pixel values with the minimum of the differences. A marker is attached to a block of pixels, such that all the pixels in that block are compared with neighbors of one direction. The marker indicates how all of the pixels in that block are compared. Intermittent Huffman-tree construction is used such that one tree is used for several frames. Huffman coding is used to compress the resulting frame. A single Huffman-tree is constructed once every predetermined number of frames. The frequency of Huffman-tree construction can be performed according to the instantaneous availability of processor time to perform the construction. When more processing time is available, the Huffman-trees are computed more frequently. Such frequency variation can be implemented by using an input video frame buffer.
