摘要:
Catalytic composites of the reaction product of a metal halide having Friedel-Crafts activity with the bound surface hydroxyl group of inorganic oxides and containing a zerovalent metal with hydrogenation activity, often are effective catalysts in motor fuel alkylation which, however, undergo rapid deactivation. Deactivated catalysts are readily regenerable by treating the composite from which alkylate feedstock has been removed with hydrogen at temperatures in the range of 10.degree. to 300.degree. C. Multiple regenerations are possible without appreciable activity loss.

A high-strength ignition coil that can reduce stress produced in a coil case and prevent a casting material from being cracked when the ignition coil is mounted on an engine block. A coil case has a mounting flange on an outer surface thereof. A coil assembly is housed in the coil case. A casting material is filled into a gap between the coil case and the coil assembly and gaps which the coil assembly has. A plurality of first guide ribs are provided on an inner wall surface of the coil case or an outer surface of the coil assembly, for positioning the outer surface of the coil assembly with respect to the inner wall surface of the coil case. A limited area in which there is no first guide rib is provided on the inner wall surface of the coil case which faces the mounting flange, or the outer surface of the coil assembly which faces the mounting flange via the inner wall surface of the coil case.

There is provided a method for connecting an insulator coated wire with a conductive member while keeping the electrical resistance low and enough joint strength at the joint section therebetween without removing the coating film of the insulator coated wire beforehand. The conductive member has upper and lower pieces which pinch the insulator coated wire, and a gap between the upper and lower pieces varies at different locations. The wire and the conductive member have a good electrical connection at a region of the joint section where the gap between the upper and lower pieces is narrow. In addition, the connection strength of the wire and the conductive member can be enhanced at a region of the joint section where the gap between the upper and lower pieces is wide.

An ink jet cartridge has a recording head portion and an ink containing portion which are detachably mountable relative to each other. The recording head portion ejects ink to effect recording with the ink. The cartridge includes a first ink container, provided in the recording head portion, for containing the ink; a second ink container, provided in the ink containing portion, for containing the ink; and an ink communication tube for establishing ink communication between the first ink container and the second ink container, wherein the ink communication tube is not externally exposed. An ink jet recording apparatus includes a recording head for ejecting ink, an ink container detachably mountable to the recording head for containing the ink to be supplied to the recording head, a detecting device for detecting mounting of the ink container to the ink jet recording apparatus and a control device for controlling a recording operation of the ink jet recording apparatus in accordance with an output of the detecting device.

An ignition apparatus for an internal combustion engine, which is controlled by a control unit, includes a connector, an ignition coil assembly, an igniter and a capacitor. The connector is electrically connected with the control unit, and includes an input terminal, which is electrically connected with the control unit to receive an ignition signal outputted by the control unit. The connector also includes a ground terminal, which is connected with a ground. The igniter includes a switching device that switches a coil current supplied to the ignition coil assembly based on the ignition signal received from the control unit through the connector. The igniter also includes a Zener diode that serves as a protection element of the switching device. The capacitor is provided in parallel with the Zener diode between the input terminal and the ground terminal to form a parallel circuit.
