Abstract: PURPOSE:To enhance the detection accuracy of the concn. of oxygen in exhaust gas by favorably holding the temp. of a semiconductor to a set temp. range by an exhaust gas sensor or air/fuel ratio controller having the same constitution even with respect to an engine different in specification, by variably adjusting the introducing amount of exhaust gas from a protector to a semiconductor type exhaust gas sensor. CONSTITUTION:In a semiconductor type exhaust gas sensor A, when a semiconductor adsorbs oxygen in exhaust gas and the resistance value thereof is changed, the concn. of oxygen in the exhaust gas is detected on the basis of said change. At this time, when the sensor A is arranged to the exhaust passage 16 of an engine 11 different in specification, the temp. of the semiconductor is different at every engine but, in this case, inner and outer protectors are rotationally adjusted in the diameter direction thereof to move the position of each exhaust gas introducing hole in the diameter direction and the exhaust gas introducing areas of the protectors are appropriately adjusted. By this method, the temp. of the semiconductor is held favorably.

Title: Keyboard
Inventor: SUZUKI SUMIO
IPC: H01H13/30
Filed: 1992-03-06
Abstract: PURPOSE:To provide a linear pushdown load property with which an after stroke can be obtained without increasing the number of part items by pressing an electrode with a seat for supporting one end of a coil spring. CONSTITUTION:When a keytop 5 is pressed, a stem 4 moves down by a load of a coil spring 7. In the meanwhile, a seat 11 is also displaced down in proportion to pressing force of the spring 7. When a certain displacement is achieved, a protrusion 12 provided under the seat 11 is installed to an electrode to obtain a gap between the electrodes and a specified contact load to turn on. When pressing-down is continued, a stroke end is reached through an after stroke. For off-action for restoration, by stopping pressing of the keytop 5, contact of the seat 11 with the electrode is released by restoration force of the spring 7 to turn off. The electrode is thus pressed by the seat 11, thereby a linear pushdown load property with which the after stroke can be obtained can be achieved without increasing the number of part items.
