Abstract: A quality evaluation method for granular objects includes the steps of: irradiating objects from a front side and a back side; taking a reflection light image and a transmission light image from both the front and back sides of the objects; obtaining optical information of the objects by image-processing the reflection and transmission light images; obtaining shape information of the objects based on the optical information; determining the quality of each of the objects based on the optical information and the shape information; and counting the numbers of objects per quality and obtaining ratios of the objects per quality against the total number of objects. The data from the front and the back sides of the granular object are analyzed to enhance the precision of the results of the quality analysis, and in particular, to enhance the precision in detecting cracks.

Abstract: A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized with work easy to do in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. A server machine section of the system includes an evaluation-destined element estimating module for estimating the evaluation-destined elements to be performed on parts constituting an article given by a design plan subjected to evaluation, a part workability evaluation module for evaluating easiness of works to be performed on the parts, an article workability evaluation module for evaluating easiness of works involved in realizing the article, and a best design plan selection/determination module for selectively determining a best structure on the basis of comparative evaluation of a plurality of design plans.

Abstract: Disclosed is a camera comprising a camera main body composed of a plurality of units including at least a lens barrel unit, a spool chamber unit and a Patrone chamber unit, a strobe unit including a strobe light emitter which is movable to a light emission possible position where strobe light emitter projects from the camera main body and an accommodating position where it is accommodated in the camera main body and a drive mechanism supported by the spool chamber unit or the Patrone chamber unit and driving the strobe unit.

Abstract: A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized easily in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. The system includes a client machine section including a guide information generating unit for generating information for guiding operations of a user, an input device for allowing the user to input commands and data and a display unit. A server machine section includes a registering unit storing evaluation elements defined by the user, an index calculating module for calculating indexes indicating degrees of difficulty/ease of work, an evaluation element estimating module, a part workability evaluation module, an article workability evaluation module, and a best design plan selection/determination module.

Abstract: The present invention provides a waterproof camera having a sealed strobe movable between a flashing position and a non-flashing position and a sealed camera body having a larger volume than the strobe.

Abstract: A picture-format switchable camera having a picture-format setting device for setting a picture format, and a picture-format switching device for switching to the picture format set by the picture-format setting device from another picture format. The picture-format switching device is disposed between the aperture of a camera body and the light-sensitive surface of a film.

Abstract: A guide roller of a tape traveling system of a video tape recorder and the like for changing the direction of travel of a magnetic tape and regulating the heightwise position of the tape during its travel including a roller body of a diameter not constant but smoothly varying axially thereof for exerting on the traveling tape a force tending to shift the tape axially. The guide roller has a flange at the top and the bottom of the roller body having a tape guide surface for contacting the edge of the tape which is not perpendicular to the axis of the roller body but convex as viewed from the respective end of the roller body, to prevent the edge of the tape from striking the edges of the flanges. The roller body may be conical at its outer peripheral surface and at the tape guide surface of each flange.

Abstract: A magnetic-tape running system for a video tape recorder having inclined pins and/or guide rollers having distant flanges. The pins and the guide rollers are inclined at suitable angles in the front and back directions and left and right directions so that the tape is guided only at its lower edge in such a manner that the tape runs stably along the cylinder lead at a constant contact pressure.
