Abstract:
A bicycle pedal comprises a pedal axle, a main pedal body, a coupling mechanism and a cleat movement restricting member. The main pedal body is rotatably supported on the pedal axle. The coupling mechanism includes a first cleat securing member and a second cleat securing member. The first cleat securing member is configured to be coupled to a front portion of a cleat. The second cleat securing member is configured to be coupled a rear portion of the cleat. The cleat movement restricting member is configured to restrict movement of the cleat in at least one direction between a frontward direction and a rearward direction. The cleat movement restricting member is further configured and arranged relative to the coupling mechanism such that the cleat movement restricting member guides the cleat during a cleat disengagement operation in which the cleat detaches from the coupling mechanism.

Abstract:
A bicycle pedal has a pedal spindle, a pedal body and a step-in cleat engagement structure. The pedal body includes a tubular mounting portion rotatably mounted on the pedal spindle. The tubular mounting portion includes a center tube section that has a widthwise dimension and a lengthwise dimension as measured from the center spindle axis to an outside surface of the center tube section along reference planes that are substantially perpendicular to each other. The widthwise dimension is substantially perpendicular to a cleat pedaling force direction applied to the pedal spindle, as viewed along in a direction of the center spindle axis. The outside surface of the center tube section has an overall transverse cross sectional shape that includes a generally convex arc that extends a majority of the outside surface of the center tube section on a side of the reference plane that faces the cleat engagement structure.
Abstract:
An optical combiner in which the number of parts used is lessened is made of a resin. The optical component comprises a first surface, a diffraction grating, and a second surface. The first surface is a surface providing first, second, and third lenses. The diffraction grating diffracts to a common optical path leading to the second surface light of the first wavelength incident on the first lens, light of the second wavelength incident on the second lens, and light of the third wavelength incident on the third lens. The second surface emits light incident thereon through the common optical path. The optical path from the first surface to the diffraction grating and the common optical path are constituted of the resin.
Abstract:
A reproducing apparatus includes a storage section, a judgment section, an analysis section, a classification section, an input section, and a reproduction section. The storage section stores a plurality of pieces of audio data. The judgment section judges, based on a length of each piece of audio data stored in the storage section, an analysis time interval for each piece of audio data. The analysis section analyzes the audio data in the analysis time interval judged by the judgment section. The classification section classifies the respective pieces of audio data into a plurality of predetermined classification items based on results of the analysis. The input section causes a user to select the classification item of the audio data to be reproduced. The reproduction section reproduces the audio data belonging to the classification item selected by the input section from a reproduction start point within the analysis time interval.
Abstract:
A processing buffer unit stores an audio signal. A pitch calculation unit and a pitch cycle correction unit calculate a multiple of N as the number of samples in a pitch cycle of the audio signal, in which N is an integer equal to or more than 1. A processing control unit and a start-position movement amount correction unit sequentially determine, as a sample in a start position of a compression process in a time axis domain of the audio signal, a (multiple of N)-th sample from a start position immediately before the start position. An operation unit compresses samples in a predetermined number times the pitch cycle from the sample in the start position in a time axis domain, and sets the number of samples after the compression to be the multiple of N. The present technology, for example, may be applied to an audio signal processing apparatus.
