Abstract: There is provided an electronic apparatus that can recover easily even when failing to update version up of a program and can be started without resort to special operation even when the program changes to change the storage format of setting information. The apparatus has a central processing unit for controlling the whole of the apparatus, a writable and nonvolatile memory for storing programs and setting information and a random access memory uses as a work area. The nonvolatile memory has at least three program areas.

Abstract: A movable enclosure contains optical components, such as an objective lens, a semiconductor laser, a mirror, and a photodetector. The movable enclosure is supported by a fixed member via a plurality of wires that are positioned in parallel. This construction allows the movable enclosure to move in a tracking direction and a focusing direction. The plurality of wires are insulated from one another to be also used as power-supplying lines and signal lines for the semiconductor laser and the photodetector.

Abstract: Inventive two-dimensional barcodes, each having encoded digital information in a bitmap representing preferably randomized encoded data bits, are printed onto a printed medium. Preferably, error correction codes are added to the digital information to ensure that the decoding process accurately reproduce the digital information. In one embodiment, the bitmap may further include “anchor” bits in each corner, which are used as part of the skew estimation and deskewing processes during decoding. In a second embodiment, no “anchor” bits are required. The encoded digital information is mapped into the two-dimensional barcode in such a way as to minimize the errors caused by damage to particular rows and/or columns, for example, row damage caused by faxing the printed barcode. To extract the encoded digital information from the printed medium, the printed medium is scanned, then the bitmap is located within the printed medium.

Abstract: A method of and apparatus for feeding electronic components are provided in which a group of electronic components joined to each other and stored in a stick are separated from each other before being supplied, regardless of the configuration at the joining ends of the electronic components as well as the presence of burrs developed during a molding process of the electronic components. In particular, a separating unit (6) comprises a step (20) which is dropped in level at the front end of a tilted chute (4) for receiving the forefront electronic component (2) and an arm (22) for holding down the succeeding electronic component (2) from above and causing the same to move backward along the tilted chute (4).

Abstract: A layout area includes a clock interconnection consisting of an upward interconnection and a downward interconnection. The upward interconnection extends from the output terminal of a clock buffer which receives an external clock signal to a turning point while passing along the vicinity of a plurality of flip-flops. The downward interconnection extends from the turning point to a free end, reversing along the upward interconnection. Clock branch circuits are provided in the vicinity of the flip-flops. The clock branch circuits have a function of letting a third clock signal make a transition when the sum of the time integral of a first clock signal on the upward interconnection and the time integral of a second clock signal on the downward interconnection has become equal to the time integral for one pulse of one of the first clock signal and the second clock signal.

Abstract: The present invention is intended to remove foreign matter such as worn powder in a refrigerating cycle and enhance the reliability in a refrigerating cycle using, in particular, HFC refrigerant. In the invention, accordingly, a coil shaped connection piping is provided in at least front portion or rear portion of a throttling unit, a fine pipe is connected to a lower portion of the connection piping, and a collector for collecting foreign matter in the refrigerating cycle is coupled to this fine pipe. Foreign matter in the refrigerant is separated from the refrigerant by centrifugal force, and is collected in the collector. Moreover, the foreign matter collecting effect is enhanced by disposing a magnetic piece in the collector.

Abstract: A new predictive coding is used to increase the temporal frame rate and coding efficiency without introducing excessive delay. Currently the motion vector for the blocks in the bi-directionally predicted frame is derived from the motion vector of the corresponding block in the forward predicted frame using a linear motion model. This however is not effective when the motion in the image sequence is not linear. The efficiency of this method can be further improved if a non-linear motion model is used. In this model a delta motion vector is added to or subtracted from the derived forward and backward motion vector, respectively. The encoder performs an additional search to determine if there is a need for the delta motion vector. The presence of this delta motion vector in the transmitted bitstream is signalled to the decoder which then takes the appropriate action to make use of the delta motion vector to derive the effective forward and backward motion vectors for the bi-directionally predicted block.

Abstract: A rotary polygon mirror has reflecting mirror faces formed at side faces of a prism of a predetermined height, and includes an axially symmetrical projection formed along at least parts of outer peripheral edges of the prism on upper and lower faces of the prism.

Abstract: A method is disclosed for producing a composite electrode which can be configured in a battery. The method comprises steps of (1) preparing a solution of an organic disulfide compound in 2-pyrrolidone or its derivative, (2) adding polyaniline to the solution to dissolve, thereby obtaining a homogeneous liquid, and then (3) removing at least a part of the 2-pyrrolidone or its derivative from the homogeneous liquid to obtain a solid product wherein the organic disulfide compound and the polyaniline are homogeneously mixed.
