Abstract:
A thick film resistor composition, comprising a silicide powder composed of a molybdenum disilicide, a tantalum disilicide and a magnesium silicide, and an alkaline earth borosilicate glass powder dispersed in a vehicle containing a heat-depolymerizing organic polymer. The thick film resistor composition, employing this heat-depolymerizing organic polymer, can be fired in a nonoxidizing atmosphere and coexist with base metal materials such as copper electrodes. Owing to the Nb.sub.2 O.sub.5 and Ta.sub.2 O.sub.5 contained in the alkaline earth borosilicate glass powder, the thick film resistor composition is free from sheet resistivity fluctuation, according to resistor length, which would result from diffusion of the electrode material into the resistor.

The invention relates to glaze resistors which are used for electronic parts of hybrid integrated circuit devices, chip resistors, resistor network, etc. The glaze resistor comprises 4.0 to 70.0 wt % of a conductive component composed of a metal silicide and a metal boride and 30.0 to 96.0 wt % of glass in which a rate of said metal boride is 1.0 to 68.0 wt %. Thus, the glaze resistor can be formed by sintering in a non-oxidizing atmosphere and can provide a circuit, together with conductor pattern of base metals such as Cu.
Abstract:
A manufacturing method for a multilayered ceramic body using Cu, Ni, Co or Fe as a conductor material, and a conductor forming paste of a particular composition of CuO, NiO, CoO or Fe.sub.2 O.sub.3 as the main component, the paste being applied to the multilayered body. The manufacturing method comprises: a process of forming the multilayered body with conductor paste of CuO, NiO, CoO or Fe.sub.2 O.sub.3 as the main component and insulating paste formed of glass and/or ceramic, so that a binder is removed from the laminate by heat treatment in an oxidizing atmosphere; a process of heat treatment for reducing the oxide; and a sintering process for sintering the laminate in a nitrogen atmosphere.

Abstract:
A bending tool that may be used for bending elongated works and in which the works are not likely to be damaged is provided. An angle formed by a blade parting line L1, L2 and an outside edge of a blade of each die is made larger than an angle formed by the blade parting line L1, L2 and an inside edge. An inner end edge of the bending block of one of dies is chamfered to be parallel to the outside edge of the blade and the inside edge is shorter than the length of the inner end edge 16C, 26C. The blade parting line L1 of one of the dies is located at a position further toward the blade parting line L2 of the other of the dies with respect to the center of the space between the blade parting line and the inner end edge of the bending block.
Abstract:
A lamination ceramic chip inductor includes at least one pair of insulation layers; and at least one conductive pattern which is interposed between the at least one pair of insulation layers and forming a conductive coil. At least one conductive pattern includes a conductive pattern formed as a result of electroforming.
Abstract:
A method for producing a conductive pattern includes the steps of forming a mask layer on a conductive base plate, the mask layer having a pattern defining an exposed area of the conductive base plate; forming a conductive pattern on the exposed area of the conductive base plate by electroforming using a plating liquid which substantially maintains the pattern of the mask layer; and transferring the conductive pattern onto a support layer without removing the mask layer.
Abstract:
A voltage-dependent resistor comprising a sintered body comprising ZnO as a major part and Bi.sub.2 O.sub.3 and GeO.sub.2 as additives with electrodes applied to the opposite surfaces of the sintered body. This voltage-dependent resistor has a low C-value and a high n-value in I=(V/C).sup.n along with high power dissipation for surge energy and high stability to a high D.C. load. Further, other additives such as NiO, Co.sub.2 O.sub.3, MnO, TiO.sub.2 and Cr.sub.2 O.sub.3 can advantageously be added to the sintered body.
