摘要:
An oxygen sensor element is manufactured by successively forming on the outside of the output lead wire, a solid pole, a first metal electrode layer, a solid electrolyte layer, and a second metal electrode layer from inside to outside.
摘要:
In an oxygen concentration cell having metal electrodes formed on both inner and outer wall surfaces of its solid electrolyte vessel and a solid pole as a reference oxygen partial pressure source made of a metal alone or a mixture of a metal and an oxide of the metal filled in said vessel, a method of activating said oxygen concentration cell by heat-treating the cell so as to diffuse the metal of said reference oxygen partial pressure source into said metal electrode on the inner wall or into said solid electrolyte through the metal on the inner wall surface and the oxygen concentration cell produced by this method.
摘要:
The present invention relates to an oxygen concentration detector to be used in a system which can simultaneously dispose of the three harmful elements in automotive emissions, i.e., unburnt hydrocarbons (unburnt HC), carbon monoxide (CO) and nitrogen oxides (NOx) through reaction with catalyst. In said detector an oxygen concentration cell comprises a solid electrolyte of a special ceramic material characterized by oxygen ion-conductivity; and the oxygen concentration of a measured gas can be analyzed by measuring the electromotive force generated through a difference in the oxygen partial pressure between the measured gas and a reference gas.

A method of disassembling a washing machine is a disassembling method for a washing machine including a reduction-gear unit secured on the outside of a water tub and a dehydration tub disposed in the water tub, and the method includes a release step of applying force, along the axial direction of a rotary shaft, in the direction of separating the reduction-gear unit and the dehydration tub from each other to release connection between the reduction-gear unit and the dehydration tub. This scheme can be employed to provide a method of disassembling a washing machine that can recover resin included in the washing machine at a high recovery ratio.
摘要:
Method and equipment for control of an internal combustion engine with a fuel-reforming device wherein air passing through the fuel-reforming device is mechanically controlled depending on the volume of air to be sucked into the engine without passing through the fuel-reforming device and is supplied into the air not passing through the fuel-reforming device, upstream of a throttle valve by means of an air pump; the total air volume sucked into the engine is detected; and the volume of fuel matching the total air volume is electrically controlled so that it can be supplied upstream of the fuel-reforming device into the air passing through the fuel-reforming device, and if necessary, also into the air not passing through the fuel-reforming device.

A method of disassembling a washing machine is a disassembling method for a washing machine including a reduction-gear unit (66) secured on the outside of a water tub (65) and a dehydration tub (12) disposed in the water tub (65), and the method includes a release step of applying force, along the axial direction of a rotary shaft (16), in the direction of separating the reduction-gear unit (66) and the dehydration tub (12) from each other to release connection between the reduction-gear unit (66) and the dehydration tub (12). This scheme can be employed to provide a method of disassembling a washing machine that can recover resin included in the washing machine at a high recovery ratio.
