Abstract: Implantable defibrillators are implanted into the chests of patients prone to suffering ventricular fibrillation, a potentially fatal heart condition. A critical component in these devices is an aluminum electrolytic capacitors, which stores and delivers one or more life-saving bursts of electric charge to a fibrillating heart. These capacitors make up about one third the total size of the defibrillators. Unfortunately, conventional manufacturers of these capacitors have paid little or no attention to reducing the size of these capacitors through improved capacitor packaging. Accordingly, the inventors contravened several conventional manufacturing principles and practices to devise unique space-saving packaging that allows dramatic size reduction.

The plurality of anode stacks include a first anode stack disposed adjacent to the upper inner surface.

Abstract: A family of spacers of various sizes for securing a standardized terminating electrical protection device (such as one of the “snap-cap” type) to an electrical energy power source (i.e., a lithium electrochemical cell) is described. The terminating protection device is mounted on a header for an electrochemical cell and contains a circuit board provided with electrical components, such as diodes and fuses. The function of the circuit board is generally to protect the cell from being overcharged or too rapidly discharged, and the like. The spacers are sized to take up the space between the edge of the cell and the edge of the terminating protection device. That way, only variously sized spacers need to be stocked. The spacers are relatively simple to manufacture and inexpensive to stock.

Abstract: In a second generation fuel cell, hydrogen and oxygen are produced by the chemical dissociation of water with the simultaneous generation of electron charged hydroxyl ions. Alkali metals, termed initiators, and alkaline earths, termed moderators, react exothermally with water in the cathode compartment to generate charged hydroxyl ionic current flow in an amount corresponding to the electrochemical equivalence of the weight of each type material reacted. The ionic electron current flow resulting from the chemical reactions occurring in the cathode compartment is discharged on the outer surfaces of a metal conduit acting as a capacitor plate, and are electrically conducted through its metal wall and deposited on the inner surfaces of the metal conduit. The build up of electron charge on the inner wall reaches a critical potential and emits electrons to receptor hydroxyl ions of the passive receptor anodic electrolyte circuit flowing through the metal conduit.

Abstract: A dielectric ceramic is composed of ABO3 as the main component and a rare earth element, wherein A represents barium which may be partly replaced with at least one of calcium and strontium, and B represents titanium which may be partly replaced with at least one selected from zirconium and hafnium. At least 70% of crystal grains of the dielectric ceramic have a cross-section in which a first region containing dissolved rare earth element occupies 5 to 70% of the area of the cross section and a second region free of the dissolved rare earth element occupies 10 to 80% of the periphery of the cross-section. A monolithic ceramic capacitor having thin dielectric ceramic layers composed of this dielectric ceramic exhibits superior capacitance-temperature characteristics and high reliability.

Abstract: Resin thin films (12) and metal thin films (11a, 11b) are layered in alternation. The metal thin films are set back from the peripheral edges of the resin thin films (12). Via holes (13a, 13b) penetrating the layered product in the layering direction are formed and filled with conductive material (14a, 14b). The conductive material (14a, 14b) electrically connects the metal thin films (11a, 11b) among one another. The metal thin films are not exposed at the periphery, so that corrosion of the metal thin films is not likely to occur. Furthermore, cutting of the metal thin films during the manufacturing process is avoided.

The housing has an indentation that forms a substantially flat contact area with the electrode stack. A method for producing the electrochemical cell includes inserting the electrode stack into the housing, bringing a die into contact with the housing, the die having a head with at least three contact points that come into contact with the housing, and stamping the die onto the housing to form the indentation.

Abstract: A data storage device mounting apparatus includes a retaining bracket (20) fixedly mounted to a computer chassis (10), two slide rails (40) attached to opposite sides of a data storage device (50), and a resilient operation body (30). The retaining bracket includes two opposite side plates (21, 22) each defining a long slot (24). Each slide rail includes protrusions (42) slidably engaging in a corresponding slot. One side plate includes a detent tab (28). One slide rail includes a blocking tab (46). The operation body is fixed to one side plate, and includes an inward projection (33). When the data storage device is slid into the retaining bracket, the projection snappingly engages with the blocking tab, to prevent accidental withdrawal of the data storage device from the retaining bracket. The detent tab abuts an end of the data storage device, to prevent the data storage device from moving further inwardly.

Abstract: A solid electrolytic capacitor includes a bulb-metal sheet of which first face has a porous section. A dielectric film, a solid electrolyte layer, and a current-collecting layer are formed in this order on the porous section. On top of the current-collecting layer, a reinforcing plate is bonded. A second face opposite to the first face of the sheet has a connecting terminal conductive to the current-collecting layer. This connecting terminal is coupled to a through-hole electrode which extends through the bulb-metal sheet for appearing outside the second face. The second face has another connecting terminal conductive to the bulb-metal sheet. This structure makes the capacitor thin, and allows the capacitor to increase its stress-resistance and be excellent in responsiveness to a high frequency as well as in mounting convenience.

Abstract: A capacitor including a plurality of layers each including a plurality of conductive plates is described. A gap separates conductive plates on a same layer. The conductive plates on a single layer assures that the total capacitance of each layer is not lost if all connections to one plate are defective. Each of the conductive plates includes a plurality of connection points or tabs to provide a redundancy of connections to each plate. The greater the number of connection points in the capacitor the lower the inductance and resistance.

The length of the conductive material connecting the capacitor to the die is short, and the inductance and resistance of the conductive material is low.

Abstract: A single layer capacitive device and a method of making the same are provided. Such method allows for perfect registration between the capacitive plates thus eliminating any significant amount of fringe capacitance and assuring a uniform fringe border around the device. Such a border ensures ease of handling and such method allows for a controlled border in a range of from about 0.5 mils to about 2.0 mils wide. Further, such a method allows for the manufacture of single layer capacitive arrays comprising numerous individual capacitive devices with similar perfect registration and uniform fringe borders. Such devices allow for improved volumetric efficiencies and reduced fringe capacitance, thus offering higher capacitor values in a smaller package size due to greater control during finishing processes.
