Title: Catalyst deterioration detecting device of internal combustion engine
Inventor: SEKI YASUNARI
IPC: F01N3/24
Filed: 1992-03-10
Abstract: PURPOSE:To judge deterioration of a catalyst certainly even if O2 storage performance of the catalyst is changed according to a temperature. CONSTITUTION:In a CPU 15, a deterioration judging value corresponding to a catalyst temperature detected by a catalyst temperature sensor 13, is outputted, after being retrieved from, for example, a judging value table. In the CPU 15, deterioration of the catalyst is detected on the basis of output of O2 sensors (FS), (RS) and a retrieved judging value. It is thus possible to correct the judging value according to temperature characteristic of the catalyst.

Filed: 1984-04-28
Abstract: PURPOSE:To prevent the occurrence of knocking so effectively, by dividing such a cylinder group that knocking is estimated among all cylinders into subgroups, while compensating the ignition timing of some cylinders alone in the same group in which the knocking happened to the timing lag side simultaneously. CONSTITUTION:This controller is provided with a knocking detection circuit 13 which detects the occurrence of knocking from output of a vibration sensor 9 for detecting an engine vibration. On the basis of output of a crank angle sensor 8, those cylinders under an explosion stroke are discriminated, and with the discrimination result and the output of the knocking detection circuit 13, it is also provided with an MPU10 compensating the ignition timing of these cylinders concerned. The MPU10 is constituted to compensate the ignition timing of other cylinders being correlative as to the occurrence of knocking to the timing lag side as far as the specified value on the basis of the comparative discrimination result between the detected knocking level and the reference level and the cylinder discrimination result. With this constitution, the knocking of the other cylinders where knocking occurrence is estimated is made so as to be preventable before it happens.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy in brazing of a metal body and a lead terminal by jointing the metal body to a metal jointing surface formed on one side surface of stem ceramic, and forming a step part for coming in contact with the periphery of a hole of the metal body in the lead terminal for inserting into the hole of the metal body to be jointed to the metal body. SOLUTION: When brazing is conducted, a brazing material placed on a metal body jointing surface of stem ceramic is melted, and flows into between the periphery of a hole 13 of a metal body 12 and a step part 11 through the capillary phenomenon. Since the step part 11 formed over the entire circumference of a lead terminal 9 is placed at the periphery of the hole 13 of the metal body 12, the brazing material flows surely over the entire circumference in between the step part 11 of the lead terminal 9 and the periphery of the hole 13 of the metal body 12, and the generation of gaps between the lead terminal 9 in the brazing part and the periphery of the hole 13 of the metal body 12 can be prevented. The height of the lead terminal 9 is surely regulated by the step part 11, brazing is prevented, and assembling accuracy is improved.

Title: Processing method by laser beam
Inventor: ADACHI SHIGERU
IPC: B23K26/142
Filed: 1985-04-24
Abstract: PURPOSE:To make possible the adjustment of a focal position by passing fluid through which a laser beam passes at all times stop a condenser lens below a work to wash away the generated vapor and sputter and adjusting the thickness of the fluid so as to focus always the beam to the processing surface. CONSTITUTION:The laser beam 2 passes through the fluid 8 of the prescribed thickness flowing atop the condenser lens 4. The vapor and sputter 7 generated from the work 5 are thereby incorporated into the fluid 8 by the laser beam 2 irradiated on the processing surface of the work 5 and are thereby prevented from sticking to the lens 4. The vapor and sputter 7 in the fluid 8 are fed together with the fluid 8 through a piping 18 into a filter 14, by which the vapor and sputter are removed. As a result, the fluid 8 supplied again atop the lens 4 through a fluid supplying port 11 does not contain the vapor and sputter 7 and therefore the lens 4 is protected. The matching of the processing surface of the work 5 and the focus of the laser beam 2 is executed by detecting the input intensity of the beam by a photoelectric converting element 16 and controlling the thickness of the fluid 8 by moving upward and downward a gate 9 via a servocontrol motor 10.

Title: Hot air flow generating furnace
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F24H3/04
Filed: 1985-04-23
Abstract: PURPOSE:To prevent the inner wall surface of the furnace from slagging and NOx from generating by providing a cooling gas supply portion within a wall part of a dual wall structure and forming a cooling gas ejecting port on the inner wall. CONSTITUTION:The wall part of the main furnace body has a dual wall structure, that is, an inner wall 2 and an outer wall 3, and a plurality of branched tubes are branched from the tip end of a cooling gas master tube 13 for feeding the cooling gas. The cooling gas which has been supplied into a top plate part 6A and respective side wall parts 6B-6E via respective branched tubes 14 and headers 15 prior to the firing of a burner 7, cools the inner wall 2 of the upper portion 1A, and thereafter is downwardly ejected through ejection ports 8 and 9. Accordingly, the combustion gas ejected from the burner 7 is encircled by the cooling gas from the ejection port 8 and thus the spraying of slags made of ash parts within the combustion gas is limited. Further, a gas layer 36 is formed on the inner surface of the furnace wall by means of the cooling gas from the ejection port 9, and the scattered slags are prevented from adhering to the inner surface of the furnace wall. Thus, the scattered slags fall down onto the liquid surface of a water sealed tank 32. Furthermore, the temperature of a hot air flow is lowered by the cooling gas, and the generation of NOx is suppressed.
