In a multilayer capacitor including a capacitor body, first capacitor portions and a second capacitor portion are arranged in the direction of lamination. While a resonant frequency of the first capacitor portions is set to be greater than a resonant frequency of the second capacitor portion so that the first capacitor portions contribute to low ESL, an ESR per layer of the second capacitor portion is set to be greater than an ESR per layer of the first capacitor portions so that the second capacitor portion contributes to high ESR. Furthermore, a combined ESR of the first capacitor portions is set to be less than or greater than a combined ESR of the second capacitor portion.

A connector with a locator, which prevents cracks at solder connected portions between pin contacts and a circuit board, prevents noise even in use in an environment with vibrations, and prevents deformation of the pin contacts is provided. The connector includes a plurality of pin contacts, a housing that houses and retains the rear ends of the pin contacts while leading out the front ends of the pin contacts in the same direction, and a resin-made plate-shaped locator that is attached to the housing and has a plurality of insertion holes for inserting the pin contacts to regulate the leading-out directions of the front ends of the pin contacts, wherein the locator is attached in contact with the housing side surface while its side end surface is in a warped condition.

The invention relates to a connector for interconnecting an plurality of wiring boards, a method for manufacturing the same, and a wiring board structure employing the connector. The connector has a base member having no conductivity and a conductive wire provided on a surface of the base member, and is arranged so as to be connectable to a wiring board, comprising: a conductive pressing member provided on and protruding from the wire; and a holding member provided on and protruding from a portion in the surface of the base member except where the pressing member is located, the holding member having an affixing surface attachable to the wiring board. The invention can make the wire provided on a surface of the wiring board flat, and therefore it becomes possible to secure the flexibility in designing a wiring pattern of a wiring board.

A sheet discriminating/counting machine selects sheets to be discriminated of a predetermined country or region by discrimination object selecting means, transports the sheets to be discriminated at high speed along a transporting path, and performs sheet discriminating/counting processing at a sheet discriminating/counting unit disposed along the transporting path. The sheet discriminating/counting machine comprises: a hopper to which sheets to be discriminated are supplied; a sheet transporting device for transporting sheets supplied to the hopper one by one along a transporting path with the shorter side of each sheet parallel to the transporting direction; a sheet discriminating unit disposed along the transporting path for discriminating/counting sheets; and a stacker upon which sheets fed out from the transporting path are stacked. The transporting path is provided with a curved transporting region which is curved in a U-shape partway and has a reject transport path connected to a pocket from a the subsequent downstream side transporting path. The sheet discriminating/counting machine performs discrimination processing of 1200 sheets or more per minute and has one stacker and one pocket.

An electronic multilayer ceramic component is disclosed which is less susceptible to having a crack or delamination in a sintered ceramic block and has high thermal shock resistance, high humidity resistance, and high reliability. Dimensional parameters EW, WG, T, and G of the electronic multilayer ceramic component are determined such that the following conditions are satisfied: WG/EW≧0.3; and T/G≦7.0, where EW is the width of inner electrodes, WG is the width of a side gap region between the ends of the inner electrodes and one of side faces of a sintered ceramic block, T is the thickness of a region in which the plurality of inner electrodes are laminated, and G is the thickness of one of the outermost ceramic layers parallel to the plurality of inner electrodes and located outside the region in which the plurality of inner electrodes are laminated.

There is provided a highly reliable laminated ceramic electronic part in which delamination or crack can be suppressed from occurring during a sintering process even if a number of lamination of internal electrodes is increased and a thickness of the ceramic layer is reduced and which excels in thermal shock resistance. The laminated ceramic electronic part is constructed so as to satisfy the following requirements of that a thickness of the ceramic layer is 10 .mu.m or less; a number of lamination of the internal electrodes is 200 or more; a ratio of a thickness of the internal electrode to the thickness of the ceramic layer (thickness of internal electrode/thickness of ceramic layer) is 0.10 to 0.40; and a ratio of a volume of the internal electrode to a volume of the ceramic element (volume of internal electrodes/volume of ceramic element) is 0.10 to 0.30.
摘要:
In a capacitor body of a multilayer capacitor, one second capacitor portion is sandwiched between two first capacitor portions. An ESR is controlled by setting a width of lead portions of third and fourth internal electrodes disposed in the second capacitor portion to be less than that of lead portions of first and second internal electrodes disposed in the first capacitor portions and by changing ratios between the first and second capacitor portions in the width of the lead portions and in the number of stacked internal electrodes. In the first capacitor portions, current paths from the internal electrodes to an external terminal electrode are widely distributed so that the first capacitor portions have a relatively low ESL, and accordingly, the ESL of the entire multilayer capacitor is reduced.
摘要:
In a capacitor body, a single second capacitor unit is interposed between two first capacitor units. The width direction dimension of each of extended portions of first and second internal electrodes included in the first capacitor unit is larger than the width direction dimension of each of extended portions of third and fourth internal electrodes included in the second capacitor unit. The area of each of the respective portions of a first opposed portion of the first internal electrode and a second opposed portion of the second internal electrode, the respective portions being opposed to each other, is smaller than the area of each of respective portions of opposed portions of the third and fourth internal electrodes, the respective portions being opposed to each other. Thus, a multilayer capacitor has a characteristic that is a combination of a low-ESL characteristic of the first capacitor unit and a high-ESR characteristic of the second capacitor.
摘要:
Disclosed is a non-specific reaction inhibitor for use in an immunological measurement, comprising a complex of an antibody or a fragment of the antibody capable of specifically binding to a non-specific reaction factor, and a polymer. The non-specific reaction inhibitor can inhibit a non-specific reaction which may interfere with the accurate detection or quantification of a trace substance in an immunological measurement method.
