摘要:
The present invention relates to an information providing system. More particularly, this invention relates to an information management apparatus capable of reliable management of distributed information and an information providing system employing the same information management apparatus. The information management apparatus comprises a main information reproducing means for reproducing main information recorded in a given recording medium; and a reproduction management means for managing the main information reproducing means for reproducing the main information. The present invention provides a receiving means provided with a means for recording distributed information and control information limiting the number of main information reproducing cycles on a recording medium, and a main information reproducing means provided with a reproduction disabling means for limiting the reproduction of main information.

A tape loading mechanism for a video cassette recording apparatus in which a magnetic tape held in the cassette is withdrawn therefrom by a tape loading arm and is wound around a rotary cylinder. During this time, the cassette is fixed on the upper surface of a chassis having a cam bore, which is driven by a rotary arm in which a pin inserted in the cam bore is set up. This cam bore is provided with a first cam surface having a radius of curvature equal to that of a locus of a turning movement of the pin, a second cam surface formed continuously from the first cam surface and having a radius of curvature different from that of a locus of a turning movement of the pin, and a third cam surface formed continuously from the second cam surface and having a radius of curvature equal to that of a locus of a turning movement of the pin. Accordingly, the movement of the cassette is started at a predetermined period of time after the movement of the tape loading arm has been started, and it is completed before the movement of the tape loading arm has been completed.

An arc cam member has a guide groove formed on its underside along its arced length. On its outer circumference, the cam member is provided with a first cam portion. A second cam portion is formed in the wall of the guide groove of the cam member. The ends of a first arm and a second arm are placed in contact with the first and second cam portions respectively. As the cam member is rotated, the first and second arms move, following the shapes of the first and second cam portions. The motion of the first and second arms is used to operate the recording and reproducing apparatus.

A tape loading mechanism of a video tape recorder includes a tape guide carrier for driving first and second groups of tape guides for pulling out withdrawing a tape from a cassette and winding the tape to a tape guide drum having an arcuate shape so as to rotate around the tape guide drum and drive the tape guide groups. The tape guide groups are mounted to end of the tape guide carrier and the carrier is disposed at the intermediate position of height between the first and second tape guide groups held by a positioning mechanism. Accordingly, the rotating plane of the tape guide carrier rotating around the guide drum is positioned between the first and second tape guide groups.
摘要:
The exhaust gas purifying catalyst-supported member comprises a metal carrier layer and a catalyst layer which includes an exhaust gas purifying catalyst and silicon oxide and is directly formed on a surface of the metal carrier. Silicon oxide is contained in the catalyst layer, and therefore, the adhesion of the catalyst layer to the surface of the metal carrier is excellent, so that the catalyst layer resists peeling from the metal carrier even when subjected to oscillations, such as when the exhaust gas purifying catalyst-supported member is used as a catalyst for purifying an exhaust gas from, for example, an internal combustion engine.
