Title: Pulse removing device
Inventor: DAUM WOLFGANG
IPC: H01H73/18
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device reducing a false trip of an arc protection of an analog circuit breaker type at low cost. SOLUTION: An analog circuit 10 based on a silicon control rectifier can be used in relation with a residential ark detection circuit breaker, based on analog operation. In the analog circuit 10, removing a first current pulse and a fast succeeding cycle pulse in a time damping pulse counter circuit virtually eliminates a possibility of a trip due to a false trip comprising one or two pulses caused by a burn out of a lamp. The circuit 10 removes a first arc pulse in any state, and removes a second arc pulse if the pulse follows immediately after the first pulse. In this manner, the sensitivity of a circuit breaker is reduced as low as possible while false trips are reduced drastically even if they are not eliminated completely when two consecutive large current arc pulses are generated.

Title: Cassette tape and tape running mechanism
Inventor: MAAKU JIEI RAROUETSUTO
IPC: G11B23/04
Filed: 1994-12-27
Abstract: PURPOSE: To improve the positioning accuracy of the cassette tape guide poles by piercing one of both ends of each guide pole through the opening of a corresponding bottom plate and fixing each end of the guide poles to the bottom plate by means of the epoxy resin. CONSTITUTION: The epoxy resin 125 of high viscosity is applied on the bottom surfaces of flanges 94 of the guide poles 38 and 40. Then the poles 38 and 40 are positioned above the projections 118 and 120 and moved down into the opening of a bottom plate 14. A matching face 108 is put close onto the matching faces 114 and 116 of a fixed part after the axes 39 and 41 of both poles 38 and 40 are set vertical on a reference plane RP. At the same time, the poles 38 and 40 are revolved to disperse the resin 125 between both poles 38 and 40 and the upper surface of the plate 14 and also in the opening of the plate 14. Then the resin 125 is hardened while the poles 38 and 40 are kept at each prescribed position.  Thus, the distance is decided between a point set on each of both poles 38 and 40 and the plane RP, and therefore the axes 39 and 41 are accurately set vertical and in parallel to each other. Furthermore, no setting error is caused since a cassette is connected to both poles 38 and 40 via the plate 14 only.
