Abstract: An information processing apparatus includes a communication apparatus and a different communication apparatus connected to the communication apparatus via a plurality of transmission paths. The communication apparatus includes a transmitting unit and a control unit. In response to designation of a transmission path targeted for diagnosis, selected amongst the transmission paths while the communication apparatus is in a state capable of data communication with the different communication apparatus using the transmission paths, the transmitting unit transmits a test signal to the targeted transmission path while the state capable of data communication with the different communication apparatus is maintained using remaining transmission paths of the transmission paths other than the targeted transmission path.

Abstract: A method differentiates simultaneous and sequential key strokes by detecting simultaneous key strokes if two keys are pushed within a judging time T.sub.L. The method includes the steps of (a) measuring a first time T.sub.1 from a time when a first key is pushed to a time when a second key is pushed, and a second time T.sub.2 from the time when the second key is pushed to a time when one of the first and second keys is released, (b) comparing the first and second times T.sub.1 and T.sub.2 with an arbitrary threshold function T.sub.C which is set within the judging time T.sub.L, and (c) differentiating whether key strokes of the first and second keys are simultaneous or sequential based on a comparison result of the step (b).

Abstract: An exhaust gas sensor including a compound ASnO.sub.3-.delta. wherein A is Ba, Ra, Sr or Ca to make use of the variation of resistance value of the compound. BaSnO.sub.3-.delta. and RaSnO.sub.3-.delta. are n-type semiconductors, while SrSnO.sub.3-.delta. and CaSnO.sub.3-.delta. exhibit the behavior of n-type semiconductors at the point of equivalence and the behavior of p-type semiconductors in the lean burn region. The compound ASnO.sub.3-.delta. is prepared by reacting an alkaline earth with SnO.sub.2.

Abstract: A .lambda. sensor comprising a perovskite compound ASnO.sub.3-.delta. and silica, germania, zirconia or hafnia added to the compound in an amount of 0.5 to 30 mol % per mol of the compound. Silica or like additive gives improved oxygen sensitivity and reduces the temperature dependence of the oxygen sensitivity.
