摘要:
An exhaust gas recirculation control system for an internal combustion engine comprises an exhaust gas recirculation control valve for controlling a recirculation rate for exhaust gas to be mixed with intake air which is supplied to the internal combustion engine, an oxygen sensor disposed in an intake air passage downstream of the control valve to detect the concentration of oxygen in the intake air, a control means which compares the oxygen concentration detected by the oxygen sensor with a desired oxygen concentration previously determined depending on operational conditions of the engine and controls the degree of opening of the exhaust gas recirculation control valve so as to cancel the deviation between the detected oxygen concentration and the desired oxygen concentration, a detecting means for detecting the exhaust gas recirculation rate being zero to supply a signal to the control means on the basis of the detection, and a correcting means for correcting the corresponding relation between the output of the oxygen sensor and the detected oxygen concentration on the basis of the output of the oxygen sensor when the exhaust gas recirculation rate is zero.

Disclosed herein is a method of manufacturing a base steel sheet, which method comprises combined steps of: not rolling a steel slab containing not more than 0.0070% by weight of C (hereinafter referred to briefly as "%"), not more than 0.1% of Si, not more than 0.5% of Mn, 0.010 to 0.080% of Al, not more than 0.0050% of N, not more than 0.030% of S provided that the ratio of Mn/S is not less than 10, and not more than 0.030% of P while the hot rolling being terminated at a finish temperature of not less than 800.degree. C.; cold rolling thus obtained hot rolled steel sheet in an ordinary manner; continuously annealing the cold rolled steel sheet in which heating is done up to a temperature from a recrystallization temperature to 800.degree. C., followed by cooling; and then temper rolling the annealing steel sheet at a reduction of not less than 7% by using two or more stand rolling mill, whereby the thus obtained base sheet, to be surface-treated may be utilized for a tinplate or a tin free steel in which no stretcher strain is formed even after baking treatment.
摘要:
An ignition control system of an internal combustion engine comprises spark plugs (21a to 21d), a spark plug driving means (15 to 20 and 22), a rotational angle position signal generating means (1 to 5), an ignition enabling signal generating means (6 to 14), and an ignition enabling means (23 to 27). The ignition enabling signal generating means is adapted to make predictive evaluation of the succeeding ignition timing based on the pulse signals (P.sub.1 and P.sub.2) obtained from the rotational angle position signal generating means, thereby to generate a pulse signal (R). The ignition enabling means enables the pulse signal (R) to be applied to the spark plug enabling means only during the ignition timing range allowable for the engine. The spark plug enabling means is responsive to the pulse signal (R) to cause ignition by the spark plugs. Accordingly, abnormal ignition is prevented from occurring even when the pulse signal (R) is generated at an abnormal timing due to deviation of predictive evaluation due to an abrupt change of the rotational speed of the engine and the like.

摘要:
An IP version storage section included in the server stores an IP version implemented in the destination terminal under the control of the server. A message receiving section receives a message from the source terminal. An IP version acquisition section acquires the IP version implemented in the destination terminal corresponding to the message from the IP version storage section. An IP version comparison section compares an IP version which is implemented in the source terminal and which is included in the message with the IP version which is implemented in the destination terminal and which is acquired by the IP version acquisition section. A comparison result sending section sends a result of the comparison by the IP version comparison section to an address converter which makes an address conversion so that IP versions of data frames exchanged between the source terminal and the destination terminal will match.
摘要:
The number of simultaneous connections to a SIP server is increased without degrading overall performance. If it is judged that, when a newly requested call is accepted, the number of calls whose call control data is stored in a call processing memory or the amount of the call control data stored in the call processing memory would exceed an upper limit, the call control data stored in the call processing memory for a busy call is saved in an external storage device. As the frequency of occurrence of an event is low in the case of a busy call, it becomes possible to accept the new call without degrading overall performance.

A vehicle-roadside service providing system enables a user to use even a service which is not accommodated by on-board service client equipment installed on a vehicle. A service host equipment (1) stores a service sequence that describes the content of a service. Service client equipment (6) acquires the service sequence from the service host equipment (1) through DSRC equipment (5a, 5b) at the times of execution of the service. The service sequence is sequentially executed by sequence step executing parts (4, 10) while performing data transmission and reception through communications between the service host equipment (1) and the service client equipment (6) based on the service sequence. Information insufficient in the course of the service is received from the user by a human interface part (7).
摘要:
A laser radar irradiates electromagnetic waves around a subject vehicle, detects the electromagnetic waves reflected from objects lying around the subject vehicle, and outputs a plurality of directions of scanning irradiation and detected distances from the subject vehicle to the objects in the respective directions. A recognition unit detects a relative position and relative speed of each objects lying around the subject vehicle. The recognition unit stores whether or not detection points data exists in each of M×N small regions into which X, Y coordinates are divided into a two dimensional array including a plurality of elements corresponding to the small regions. The recognition unit performs arithmetic operations of multiplication and summation of the respective elements of the two dimensional array while sequentially scanning a mask of a two dimensional array comprising J×K (J
