摘要： An air-fuel ratio controller for use in an internal combustion engine, of a type having an exhaust gas sensor disposed in the exhaust passage, a control circuit and a solenoid valve having a valve seat in which passages open leading to the air bleeds of the slow and main systems of the carburetor, the controller being adapted to actuate a valve of the solenoid valve, in accordance with a signal derived from the exhaust gas sensor, into and out of contact with the valve seat, so as to simultaneously control the flow rates of bleed air in the air bleeds of the slow and main systems. A recess is formed in the cooperating surface of the valve seat or the valve, at a position between the openings of the passages in the valve seat. This recess communicates with a chamber which in turn communicates with the air inlet. Unfavorable mutual direct communication of the passages with each other is avoided, even when a slight gap is formed between the valve seat and the valve seated on the latter due to inclination of the valve seat or the like reason, because both passages communicate with the chamber through the recess.

摘要： A boot-mounting structure for a constant velocity universal joint has a configuration which can prevent a crack caused by interference with a boot band while maintaining a stable sealing property. The boot band (69) is fitted into a fitting groove of a silicone boot (65), and is decreased in diameter while being attached into the fitting groove, to thereby fix the silicone boot (65). The boot band (69) is formed into an annular body not provided with a folded-back portion. There is provided a no-interference structure means (S) for preventing interference caused, when the boot band is decreased in diameter, between an axial outer-peripheral-edge portion (69a or 69b) of the band (69) and a bottom end portion (82a or 82b) of the fitting groove (75) corresponding thereto.

摘要： With notice taken of the facts that the conventional tripod joints are designed with particular attention paid to the aspect of strength, particularly the strength of the shaft and that in the aspect of durability there is some room in the ordinary use, while considering balance between strength and durability, the size of the shell of the outer joint member is reduced as much as possible, so that weight reduction and compactification of the tripod joint are achieved.

摘要： Disclosed is an apparatus for controlling the amount of secondary air fed into an internal combustion engine. The apparatus includes an independent means for rapidly applying an absolute pressure signal to a secondary air flow control means, so that secondary air is rapidly supplied into the engine when the secondary air flow control means is being reset in its initial position, and then, next, a rich signal is applied. Thus, the equivalent air-fuel ratio can be correctly controlled, without delay, in response to changes in the operating condition of the engine.

摘要： A diamond drill consists of a core and a pair of abrasive diamond tips which are joined to constitute a diamond tip and core assembly in the form of a flat plate. The diamond tips have chamfering sections for providing a cutting blade of a diameter smaller than that of a cutting blade provided by finishing blade sections thereof. The chamfering sections can be used not only for chamfering an edge of a glass plate defining an opening but for cutting a non-circular opening. In another embodiment, an abrasive diamond ring is installed on a shank and used for chamfering an edge of a glass plate defining an opening or for cutting a non-circular opening having a small corner.
