Non-contact information storage medium and data transmission method for the medium

A non-contact information storage medium (106) for receiving power from a card reader/writer (101) via an antenna (107), using the power for driving its internal circuit, and simultaneously transmitting data as a transmission wave to the outside thereof. The output current of a rectifier circuit (109) is interrupted by a switching circuit incorporated in a modulation circuit (110) in accordance with the transmission wave. In the period of interruption, the output voltage of the rectifier circuit (109) is limited by a voltage limiting circuit incorporated in the modulation circuit (110) to a value not more than the breakdown voltage of elements which constitute the circuit. The loss of power during data transmission is extremely small, and hence the circuit can be constituted by elements of a usual breakdown voltage.

Control apparatus

This invention relates to a control apparatus of a multistage setting type in which, when input pulses are counted and the counted values are compared with some of a plurality of preset points to see whether the former are larger or smaller than or equal to the latter, an output signal is supplied and indicated on the basis ofthe results of the comparison action. As the apparatus has such a construction that the preset points are set and memorized electrically. a number of points can be preset and the volume of the apparatus can be minimized. Further, in order to compare the input pulses with the preset points, two comparators are used. Into one of the comparators, the counted values and a preset point smaller than, but nearest to, the counted value are put in together, and at the same time, into another comparator, a preset point larger than, but nearest to, the counted value are put in together. Therefore the period of calculation is extremely short.

APPARATUS AND METHOD FOR CONTROLLING THE AIR-TO-FUEL RATIO IN A DIRECT INJECTION INTERNAL COMBUSTION ENGINE

Dans une commande par rétroaction du rapport air-carburant, une quantité de saut riche est rendue plus grande qu'une quantité de saut pauvre par une quantité de décalage OS, de telle sorte qu'un centre de commande par rétroaction est décalé du côté riche. En résultat, la quantité d'erreur provenant d'une détection erronée par un capteur O2 est absorbée, et la détérioration des émissions de gaz dans un mode d'injection multiple est minimisée. In an air-fuel ratio feedback control, a rich jump amount is made larger than a lean jump amount by an OS shift amount, so that a feedback control center is shifted to the rich side. . As a result, the amount of error from erroneous detection by an O2 sensor is absorbed, and the deterioration of gas emissions in a multiple injection mode is minimized.
