Abstract: A method of manufacturing an exhaust gas sensor includes providing a sensor element having an open end, a closed end, and an inner surface defining a chamber between the open and closed ends. The method further includes inserting a nozzle into the chamber, supplying an electrode material to the nozzle, and without substantially any relative movement between the nozzle and the sensor element, atomizing the electrode material to form a mist of electrode material that substantially surrounds the tip of the nozzle and deposits onto the inner surface of the sensor element to form an inner electrode.

Abstract: A tool box is formed with two counter bores, and includes a handle formed with headed latches. Each of the counter bores has an upper enlarged section and a lower constricted section confined by an inward flange. Each of the headed latches includes an enlarged head received in the enlarged section of the respective counter bore, and a bifurcated shank having a pair of elastic legs that are respectively formed with barbed ends, and extending through the constricted section of the respective counter bore such that the flange is sandwiched between the enlarged head and the barbed ends of the elastic legs.

Abstract: A tool storage unit includes left and right walls, and a bottom wall. A left protrusion projects from an upper segment of the left wall toward the right wall for urging a front end wall of a socket. A right protrusion projects from an intermediate segment of the right wall toward the left wall for abutting against a central depressed area in a rear end wall of the socket. A plurality of the tool storage units are interconnected in a row for storing a plurality of sockets, in which the left protrusions on the left walls of the tool storage units are formed as a continuous projection that extends across the left walls.

Abstract: A tool box includes a case body and two side plates. The case body includes base and cover parts. The lateral sides of the base and cover parts have peripheral flanges that extend along the peripheries of the lateral sides to confine cavity halves. The peripheral flanges of the base part have opposite sides formed with first engagement portions. Each of the side plates has a lower portion formed with a second engagement portion that engages releasably a corresponding one of the first engagement portions. The side plates further have outer surfaces adapted to be provided with marks. The lower and upper portions of the side plates are retained in respective cavity halves of the base and cover parts. Stop members project from the peripheral flanges adjacent to the end faces outwardly of the cavities.

Abstract: N bit-collision circuits of a collision detection circuit each include a bit-collision circuit driver connected to drive an x-th line of the common collision detection bus if the x-th line of the station's corresponding identifier signal is at a low level. The bits of the identifier signal are only provided to the bit-collision circuit drivers while an enable signal is asserted. The driver has an open-collector-type connection to the x-th line of the common collision detection bus. That is, the bit-collision circuit driver, when not driving, presents a high impedance at its output. Each bit-collision circuit further includes an XOR device for use in comparing the level of the x-th line of the collision bus with the level of the x-th bit of the station's identifier signal. A NOR device is for combining receives the comparison results from the XOR devices of the bit-collision circuits and provides a combined bit-collision result.
