Abstract: A jumper chip component of the present invention includes a connection conductor formed of a conductive layer over an upper face and opposite side faces of an insulating substrate, and a conductive material formed of a conductive layer between plates of the insulating substrate and on a side face at the corner of the insulating substrate so as not to be electrically connected to the connection conductor. Since the conductive material formed between the plates of the insulating substrate opposes the connection conductor formed on the upper face of the insulating substrate, the connection conductor formed on the upper face of the insulating substrate and a second conductive pattern disposed under the insulating substrate are shielded from each other by the conductive material, and good isolation is possible.

Abstract: A control device for a spark-ignition engine, in which a mixture in a combustion chamber is fired by compression ignition in a part-load range under warm-running conditions, includes an EGR controller incorporating a valve operation controller for controlling internal EGR of hot burned gas and a cold EGR controller for controlling external EGR of cold burned gas. The EGR controller performs EGR control operation to leave the hot EGR gas in the combustion chamber in a lower-load, lower-speed region within a compression ignition combustion range and to introduce the cold EGR gas into the combustion chamber in a higher-load, higher-speed region within the compression ignition combustion range. The control device further includes a firing assist unit for inducing the compression ignition at least when ignitability of the mixture decreases due to introduction of the cold EGR gas in the compression ignition combustion range.

Abstract: A shielding case eliminates the problem in that the fixing portion of a feed-through capacitor juts out of the cabinet thereof; it does not affect the mounting conditions or the like of internal electronic components even if a part of the cabinet is bent inward to provide a portion on which the feed-through capacitor is mounted; and it enables automated assembly. The shielding case provides all the aforesaid advantages without sacrificing the shielding effect thereof.

Abstract: A shielding case ensures no deterioration in shielding effect, and allows a printed circuit board (PCB) to be installed from under the frame thereof and a leader terminal to be also installed from above the opening thereof.
