Abstract:
A code comprises data patterns recorded according to a piece of information and markers arranged at predetermined respective positions relative to the data, patterns and used to determine the position for reading each of the data patterns. The data patterns and the markers are optically readably recorded in different modes. An image memory section stores the optically readable image of the code picked up by an imaging section. An attribute determining section determines the attribute of the image stored in the image memory section on the basis of a unit of a plurality of adjacently arranged pixels selected as a function of the size of the markers and a marker detecting section detects the markers on the basis of the attribute determined by the attribute determining section. A data reading section determines the position for reading the data pattern on the basis of the detected positions of the markers and actually read the data.
Abstract:
An illumination section illuminates a code on a recording medium, on which data about audio information is recorded as an optically readable code, by repeatedly emitting light at predetermined intervals. An image sensing section receives each of light beams reflected by the recording medium including the code illuminated by the illumination section in a read/scan operation for the code, and outputs a corresponding image sensing signal. A signal processing section decodes the data about the audio information by processing the image sensing signal output from the image sensing section. A reproduction output section reproduces the audio information on the basis of the data decoded by the signal processing section and outputs the information. A supply voltage detection section detects a supply voltage to a power supply circuit system including a battery used as a power supply of the apparatus. A detection timing control section controls the supply voltage detection section to detect the supply voltage at a predetermined timing in image sensing operation performed by the image sensing section at the time of light emission after the supply voltage to the power supply circuit system is turned on by a power switch and first light emission is performed by the illumination section.
Abstract:
A process is provided for the production of a porous retainer for use in a rolling bearing for holding rolling elements. The process comprises the following steps:(1) blending a polyimide resin, which serves as a porous matrix material for the porous retainer, with another heat-resistant resin which has a forming temperature range close to the polyimide resin and, when treated with a solvent in the presence of the polyimide resin, is solely dissolved out;(2) forming the resulting resin blend into a retainer of a desired shape; and(3) treating the thus-formed retainer with the solvent, whereby the another heat-resistant resin is solely dissolved out.

An illumination apparatus includes lenses, a first casing that has a radiation plane provided with annularly arranged windows for attaching the lenses, respectively, independently, and that has an opening at a position opposite to the radiation plane, and a first substrate associated with each of the lenses and accordingly disposed. The first substrate has at least one light emitting device mounted thereon. The first casing includes a holding portion associated with each of the windows. The holding portion each permits the lens to be attached to the first casing from a side thereof having the opening and also restrains the lens from moving through the first casing toward the radiation plane, and when the lens is attached to the first casing, the lens has an optical axis in a direction having a predetermined angle relative to a center axis of the first casing.
