Abstract: An oxygen adsorbent which can be manufactured at a low cost, and an oxygen manufacturing equipment and an oxygen manufacturing method which are capable of producing oxygen-enriched gas at a low cost by using the oxygen adsorbent are provided. The oxygen adsorbent comprises at least an oxide of a perovskite structure. The oxide is represented by a compositional formula of Sr1?xCaxFeO3??, wherein 0.12?x?0.40, 0???0.5. Since this oxide does not include La and Co included in a conventional oxygen adsorbent, it can be manufactured at a low cost.

Abstract: A personal computer includes a code generation tool to generate a source code from a given model compliant with a plurality of variations. From an HDD, the computer acquires the given model including a plurality of part specification blocks, each of the part specification blocks specifies a specific part of the given model. From the HDD or an input apparatus, the computer acquires selection information indicating that a given specific part of the given model is to be selected or deleted using the corresponding part specification block. Based on the selection information, the computer thereby generates a source code from an intermediate model where unnecessary part is deleted from the given model.

Abstract: The re-use property of a vehicular controller service program is improved by providing a structure capable of easily changing the method of communication to/from an external apparatus and a structure capable of easily changing the vehicle information required for such communication. A service management object communicates with an external scanning tool which is constituted separately from a service execution object including objects for obtaining the fault information. Each individual object thus implements only either communication function with the scanning tool or a vehicle information acquisition function. Thus when changes are required for one of these functions, the remaining object-oriented program modules can be re-used without change. The service execution object may be prepared to obtain every category of fault information desired depending on legislation or vehicle manufacturer requirements.

Abstract: A self-diagnosis program for a vehicle is object-oriented designed. The self-diagnosis program is provided with a malfunction detection object for detecting a malfunction provided for each malfunction detection processing, and a malfunction information storage object for storing the malfunction information provided for each malfunction item. A malfunction information management object has the correlative relation between the malfunction detection object and the malfunction information storage object. Upon receiving a normality/abnormality message from the malfunction detection object, the malfunction information management object determines the corresponding malfunction information storage object and stores the malfunction information.

Abstract: To enable easier change of a self-diagnostic program for making a contribution towards improvement in quality of the same program, even if it is required to correct an execution condition for fault detection due to the change of a diagnosis object, a diagnostic drive determination object is provided to determine the execution condition of a fault detection object driven from a diagnostic scheduler object. The diagnostic scheduler object determines the fault detection object of the drive object and requests the drive acknowledgment to the diagnostic drive determination object. Upon issuance of the drive acknowledgment request, the diagnostic drive determination object obtains the information required for the execution condition determination and notifies a drive acknowledgment/non-acknowledgment message. Only when the acknowledgment message is notified, does the diagnostic scheduler object issue a drive instruction to the fault detection object of the diagnostic object.

Abstract: Each malfunction-information storing object is prepared for each corresponding malfunction check item that is consistent with a corresponding diagnosis target. The malfunction-information storing object specifies a control instruction with respect to each corresponding malfunction information. A malfunction-information managing object adjusts the specified control instruction and outputs final MIL information. In an operation that is conducted separately from an operation that is triggered by a malfunction detection request, an MIL controlling object outputs an MIL information request upon receiving an MIL state renewal request from a platform. Upon receiving the MIL information request, the malfunction-information managing object outputs the MIL information. Adjustment of a result of a malfunction determination operation and an MIL control operation are carried out separately by the malfunction-information managing object and the MIL controlling object, separately.

Abstract: A control method and apparatus which detects a solenoid current as a voltage, and PWM-controls a transistor for a solenoid such that the detection voltage becomes a target voltage. A feedback gain, used for setting PWM signal output time, is set in accordance with the difference between the detection voltage and the target voltage such that the greater the difference becomes, the greater the feedback gain becomes. Further, a detection voltage after a predetermined period is estimated based on the change of detection voltage from the past. If the estimation value overshoots the target voltage, a difference B between the detection voltage and the target voltage and a difference C between the detection voltage and the estimation value are obtained, and the feedback gain is varied by multiplying the feedback gain by the ratio B/C between the these differences.
