  • Patent number: 5057972
    Abstract: An electrolytic capacitor comprising a pair of electrode foils, an oxide layer provided on the surface of at least one of said electrode foils, an ion permeable capacitor paper interposed between said pair of electrode foils, an electrolyte being impregnated into the capacitor paper. The capacitor paper contains hydrogen reducing fine particles consisting of palladium, platinum or an alloy of both. The hydrogen reducing fine particles are distributed in the capacitor paper in an amount between 0.1 and 1% by weight based on the weight of said capacitor paper.

  • Patent number: 5055869
    Abstract: A supply magazine receives a package having a stack of film sheets within a light-tight bag. When the magazine is closed, a the bag is driven from the magazine so that the sheets can be removed for exposure and development. The bag is removed at the rear end of the magazine and fed toward the front of the magazine so that it is accessible to the operator and to avoid having the bag fall into an associated printer/processor and out of the reach of the operator.

  • Patent number: 5053915
    Abstract: The present invention relates to a capacitive sensor comprising two concentric capacitors having a common electrode, namely a high tension capacitor and an auxiliary capacitor, the sensor including two screens separating the two electrodes of the high tension capacitor, and these two screens leaving a gap between each other of constant size. The invention is applicable to metalclad stations.

  • Patent number: 5053927
    Abstract: A pocket within the molded casing of a solid electrolyte capacitor is of greater volume than a fuze passing through the pocket, thereby ensuring that the fuze will not reestablish its conductive path after being blown. The pocket is established between layers of polyester tape that insulate the cathode of the capacitor from its leadframe and protect the fuze from the molding material.

  • Patent number: 5051862
    Abstract: A stacked or coiled type of metallized flexible dielectric film capacitor is made by the direct superimposition of at least two metallized films, laterally offset with respect to one another so as to form alternating even-order and odd-order layers, designed to be connected to one another by lateral electrical connections. One of the faces of the films is entirely metallized and the gap between two same-order layers is filled with an insulator material itself covered by the lateral electrical connections.

  • Patent number: 5050043
    Abstract: A solid electrolyte capacitor in a chip stucture has a fuse element that is arranged in the anode terminal. What is achieved by applying parting locations in the anode terminal is a current path that extends by way of the anode terminal, the fuse element, an anode wire weld point, an anode wire, a sintered anode member, and a cathode contact to the cathode terminal.

  • Patent number: 5040012
    Abstract: A controller for operating an X-ray film processor at reduced speed for extended film developing includes a push-button selector coupled to a voltage regulator for providing a precisely regulated, reduced voltage to a variable speed dc drive motor for operation at slower speeds. The controller also includes override circuitry for preventing selection of one processing speed during operation at another speed to avoid improper film processing. Indicator lights are also provided to inform an operator of the mode of operation, i.e., normal or slow speed, of the film processor as well as the cumulative amount of film processed at each speed. The controller provides a continuous range of reduced operating speeds for improved contrast and image resolution and is adapted for installation as a kit with existing single speed X-ray film processors to provide a dual speed capability by a plug-in connection to existing electrical leads.

  • Patent number: 5016034
    Abstract: In a camera system of the present invention, two kinds of units which set picture factors for a camera, such as shutter speed and ISO value, can be selectively attached to the camera: one type mechanically sets the picture factors in a continuous operation; and the other type electrically sets the picture factors in a button operation. According to the above-mentioned composition, the camera system can be used as what is called a mechanical camera and as what is called a button type camera by exchanging the units. Thus, the camera system of the present invention can answer needs of a wide range.
