Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a seal ring which can seal surely between the inner peripheral surface of a case formed into a tubular form, and the outer peripheral surface of a fixed iron core, in a fuel injection valve, for example. SOLUTION: A fuel injection valve 11 furnishes a cylindrical case 12, and a fixed iron core 13 is inserted in the case 12. Between the outer periphery at the front end (the lower end in Fig.) of the iron core 13, and the inner peripheral surface at the front end of the case 12, a seal ring 18 is fitted. This seal ring 18 is composed of the first ring member 31 inserted between the case 12 and the fixed iron core 13, and the second ring member 32 assembled into the first ring member 31. In the first ring member 31, a ring groove 33 is engraved, and when the second ring member 32 is inserted and assembled into the ring groove 33, the thickness in the diameter direction of the first ring member 31 is expanded. As a result, between the inner peripheral surface of the case 12, and the outer peripheral surface of the iron core 13 is sealed surely by this seal ring 18.

Title: Vehicular failure diagnostic device
Inventor: FUJITA TATSUYA
IPC: F02M25/07
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To diagnose failure of parts with excellent accuracy, which control an exhaust emission on the basis of the detected value of an oxygen concentration sensor which detects an oxygen concentration in exhaust. SOLUTION: After an engine is started, if the detected value of an oxygen concentration sensor 17 shows an abnormal value during an idle operation period before an EGR device 21 is operated, it is diagnosed that the oxygen concentration sensor 17 is out of order. Also, the EGR device 21 is operated for a short time during an idle operation period before the EGR device 21 is operated, and the failure of the EGR device 21 is diagnosed on the basis of the variation of the detected value of the oxygen concentration sensor 17 before and after the short operation of the EGR device 21.  Further, when both EGR device 21 and turbosupercharger 13 are not operated, a fuel injection amount is increased in one air cylinder (diagnostic air cylinder) being a target to diagnose its failure, and the fuel injection amount of the other air cylinder is reduced and corrected so that the increment of the fuel injection amount of the diagnostic air cylinder is canceled, then the failure of the injector 22 of the diagnostic air cylinder is diagnosed on the basis of the detected value of the oxygen concentration sensor 17 at that time.

IPC: H01T4/10
Filed: 1989-12-08
Abstract: PURPOSE:To make maintenance and inspection of a lightning arrester easy by supporting a lead wire on the steel tower and connecting the wire from electric discharge gaps to a lightning arrester installed in a place remote from a power line while supported by a steel tower. CONSTITUTION:When lightning hits power lines 4a, 4b, 4c or a steel tower 7, electric discharge is caused between gaps 5 in series and lightning current runs to lightning arresters 1a, 1b, 1c through lead wires 2a-2c. If the period from the starting of the current running to the lead wires 2a-2c and reaching the lightning arresters 1a-1c to the returning of reflected waves to the power lines 4a-4c is, for example, at most 0.1mus and the period is short enough as that level, without troubles, the power-transmission wires 4a-4c are protected from lightning. Consequently, the installation point of each of lightning arresters 1a-1c may be remote from the power lines 4a-4c and thus maintenance and inspection of the lightning arresters are carried out at low place.
