A two-cycle internal combustion engine having an oblong cylinder and an oblong piston therein. The engine includes two sets of scavenging ports at either end of the oblong cylinder having at least three ports each. Scavenging passages extending to the scavenging ports may be directed at sequentially increasing angles of inclination to the local normal with the cylinder away from the exhaust porting. In this way, flow may be directed across the piston head away from the exhaust porting and then upwardly to return toward the exhaust porting. A domed piston is also disclosed having discrete guide surfaces on the domed surface of the piston to specifically direct incoming air/fuel mixture upwardly from each of the scavenging ports. An element of the cylinder midway in the long dimension of the cylinder extends in the direction of piston movement without porting so as to provide a smooth wall surface. An oblong piston ring mounted within a groove in the piston has a break in the ring coincide with the unported cylinder element to reduce stress and friction.

A noise processing apparatus measures a first potential difference signal, between a first electrode and a second electrode that is used as a reference electrode, and measures a second potential difference signal, between the second electrode and a third electrode that is arranged on the steering unit in the apparatus. The apparatus calculates the difference between the intensities of the first potential difference signal and the second potential difference signal calculated at the predetermined intervals. The apparatus corrects the first potential difference signal or the second potential difference signal by using the calculated difference such that the intensities of the first potential difference signal and the second potential difference signal are canceled out. The apparatus calculates a differential signal indicating the difference between the first potential difference signal and the second potential difference signal by using the corrected potential difference signal, and outputs the differential signal.

A motorcycle exhibiting improved cornering clearance has its front and rear wheels mounted to a fixed frame portion via front and rear suspensions. A moveable frame portion including the motorcycle seat is moveably mounted to the fixed frame portion and moves under control of the rider further inside a corner during cornering in order to shift the effective center of gravity of the motorcycle further inside the corner and thus further increase the lean angle of the entire motorcycle. Movement is provided via a pivot, slidable shaft, or a pair of parallel linkages. The moveable frame portion may include only the motorcycle seat or may include the tank, seat, and entire motorcycle fairing.

A photoelectric sphygmograph measurement device includes a light emitting part emitting light pulses, a light receiving part having a light receiving element that receives the light pulses and producing a corresponding output signal, and a control part driving the light emitting part to emit the light pulses and performing a pulse wave measurement by using the output signal. The control part drives the light emitting part so that a charge accumulated in the light emitting element converges on a predetermined amount in a case where the charge accumulated in the light receiving element decreases to the predetermined amount or less during a time when driving of the light emitting part is stopped and/or in a case where the light receiving element changes to a first state in which the light receiving element is capable of receiving the light pulses from a second state in which the light receiving element is not capable of receiving the light pulses.

A technique related to a data backup for a computer. There are provided a selection section, an archive file creation section, and a backup processing section. The selection section selects data files satisfying given conditions from among data files stored in a first storage section. The archive file creation section creates N (N is a natural number) archive files by grouping the plurality of data files selected by the selection section and which repeats the archive file creation processing M (M is a natural number) times. The backup processing section stores the archive files created by the archive file creation section into a second storage section. The technique enables efficient copying of a data file in a short period of time.

A data compression system is provided having a fixed length coding unit provided before a universal coding unit. The fixed length coding unit detects mode classifications and mode conditions of changing picture elements in a mode detecting unit. Then, the mode classifications and mode conditions are converted to fixed length code words in a code transforming unit representative of, e.g., MH, MR or MMR-type codes. Thereafter, the fixed length code words are predictively coded by the universal coding unit to output compressed data. The present invention is applicable to both character data and picture data. Preferably, the picture data is preprocessed by the fixed length coding unit before both of the character data and picture data are predictively coded by the universal coding unit.
