A vehicle control apparatus comprises: a computer operable to execute a control program, a first memory storing the control program, and a second memory storing the produced data. The control program includes: a platform program for inputting data from a hardware device and storing inputted data as first data in a first section of the second memory, an application program for processing for a vehicle control in accordance with an AP interface, and a coupling processing program. The coupling processing program performs mediation in the processing using the application program by converting the first data provided from the processing using the platform program to second data in accordance with the PF interface so that the second data is adapted to the AP interface. The application program executes vehicle control by using the second data. The platform program performs an operation at different predetermined intervals than the coupling program.

An apparatus is provided for managing communication among a plurality of process means respectively operating on given control programs realizing functions necessary for a vehicle. The plural process means includes a first process means issuing requesting messages for requesting a function and a second process means receiving the requesting message, performing a process requested by each requesting massage, and sending back a response indicating results of the process to the first process means. In the apparatus, storage means stores therein, of the requesting massages issued, only response-waiting messages issued by the first process means and received by the second process means. A measuring component measures an elapse of time from a time when the request stored in the storage is received by the second process means. A determining component determines whether or not the elapse of time measured by the measuring component reaches a preset value.

摘要:
An electronic control unit is incorporated as one of a plurality of electronic controllers composing a system for controlling in-vehicle devices on a distributed and mutually-synchronized control manner in a vehicle. The plurality of electronic control units are communicably connected with each other via an in-vehicle network to communicate information including the time-dependent data among the electronic control units. Each electronic control unit comprises a control member, an elapsed-time calculation component, and a validity determination component. The control member performs the control on the basis of time-dependent data acquired in time series relating to the vehicle. The elapsed-time calculation component is configured to calculate an elapsed time elapsing from acquisition of the time-dependent data. The validity determination component is configured to use the calculated elapsed time to determine whether or not the time-dependent data is valid or not for the control in terms of freshness of the time-dependent data.

The present invention provides a plasminogen fragment with the activity to inhibit tumor metastasis and growth, a process for preparing said fragment and an agent for inhibiting tumor metastasis and growth comprising said fragment as an active ingredient. The plasminogen fragment of the present invention is prepared from a elastase lysate of Lys-Plasminogen, which is produced by treating a natural plasminogen with plasmin, and preferably exhibits a strong heparin binding activity. The agent for inhibiting tumor metastasis and growth comprising the plasminogen fragment as an active ingredient of the present invention is useful for clinically treating solid cancers such as lung cancer or colon cancer.
摘要:
Control of the characteristic impedance of wirings is performed with high accuracy. Relative to a first wiring of a second wiring layer arranged above a through hole of a core layer in a package board, the thickness of a first insulating layer between a first wiring layer on the surface of the core layer and the second wiring layer is made large, and the thickness of a second insulating layer between a third wiring layer that is a plane layer on the side of opposite thereto and the second wiring layer is made small, thereby allowing for: reducing the impedance coupling between the power plane of the first wiring layer on the surface of the core layer and the first and second wirings; reinforcing the impedance coupling between the power plane of the third wiring layer on the side opposite thereto and the first and second wirings; and achieving the reduction of the difference in the characteristic impedance between the first wiring arranged just above the through hole and the second wiring arranged away from just above the through hole.
