Laminate type electronic component

A laminate type electronic component 1 comprises, at least, a dielectric part 2 containing a dielectric as a constituent material, and a pair of a first external electrode 31 and a second external electrode 32, each disposed in close contact with the dielectric part 2, opposing each other by way of the dielectric part 2. The dielectric part 2 comprises laminated dielectric layers 21a to 21f; and at least two internal electrodes 23a to 23e disposed one by one between layers adjacent each other in the dielectric layers 21a to 21f, while each being electrically connected to one of the first external electrode 31 and second external electrode 32. At least one of the internal electrodes 23a to 23e is electrically connected to the first external electrode 31, and at least one of the internal electrodes 23a to 23e is electrically connected to the second external electrode 32.
The first external electrode 31 and second external electrode 32 comprise resin electrode layers 31a and 32a, each made of a conductive resin mainly composed of a thermosetting resin and a conductive particle; a metal electrode layer 31b disposed between the resin electrode layer 31a and the dielectric part 2; and a metal electrode layer 32b disposed between the resin electrode layer 32a and the dielectric part 2. The conductive particle content in the conductive resin is 70 to 75 mass %, whereas the conductive particle contains, as a main ingredient, acicular particles 71 having an average longitudinal length of 30 to 70 μm and an aspect ratio of 1.5 to 3.3.

Process for producing infrared emitting device and infrared emitting device produced by the process

In order, to manufacture a high-performance infrared-emitting element having high-speed thermal response characteristics and a high infrared emissivity, a bridge (heat-generating) portion having a separation space is formed on a silicon element substrate. The bridge portion is formed to have a thickness of 5 mum or less by doping boron as an impurity by ion implantation with a concentration distribution peak value of 1.5x1019 atoms/cm3 or more, and performing annealing under predetermined conditions for activating the impurity layer. In the infrared-emitting element manufactured in this manner, even if the bridge portion is made thin to improve the thermal response characteristics, the infrared emissivity does not decrease because of a high impurity concentration, and a large temperature modulation width can be obtained. In doping boron as the impurity by ion implantation, the dose is preferably set to 3.0x1014 ions/cm2 or more. To activate the impurity layer upon doping boron, the annealing is performed in the nitrogen gas atmosphere at a temperature of 1,100° C. to 1,200° C. for 5 min to 40 min and further in the wet oxygen atmosphere for about 25 min to 40 min. As a result, the doping concentration of boron by ion implantation and the activation of the impurity layer can be stably increased and enhanced.

Adhesive-carrying porous film for battery separator and use thereof

The invention provides an adhesive-carrying porous film for use as a battery separator, which comprises: a substrate porous film such that when a probe of a probe penetrating thermomechanical analyzer, said probe having a diameter of 1 mm, is placed on the porous film under a load of 70 g to measure a thickness thereof while heating the porous film from room temperature at a rate of 2° C./minute, a temperature at which the thickness of the porous film decreases to a half of the thickness of the porous film when the probe was initially placed thereon is 200° C. or more; and a partially crosslinked adhesive carried on the substrate porous film, the partially crosslinked adhesive being prepared by reacting a reactive polymer having a functional group capable of reacting with an isocyanate group therein with a polyfunctional isocyanate so that the reactive polymer is partially crosslinked. Such a porous film (a separator) is temporarily bonded to an electrode to provide an electrode/separator laminate. In manufacturing a battery, the use of the laminate makes it possible to manufacture a battery efficiently with no mutual slip movement between the electrode and the separator, and is addition, the porous film (the separator) itself, after manufacturing a battery, functions as a separator which does not melt or break, and has a small heat shrinkage under high temperatures
