Abstract: PURPOSE: To keep the reliability at a higher level for a vehicle controller (ECU). CONSTITUTION: It is checked in the assembling process of an ECU 10 whether the test data are inputted to the ECU 10 from a tester connected to the ECU 10 via a communication line and also the test data are outputted to the tester from the ECU 10 in a normal way and in an actual working mode. At the same time, both circuits are directly connected to each other via the ECU 10 and the tester and a prescribed signal is exchanged between them. If the normal transfer of the test data is confirmed in the checking operation, the test data are transferred to the ECU 10 from the tester in a test case. The ECU 10 transfers again the received test data to the tester and checks the coincidence of contents between the test data transferred first from the ECU 10 and the received test data. If the coincidence is confirmed between both data, the ECU 10 is initialized.  When this initialization is completed in a normal way, it is decided that the ECU 10 is normal.

Title: Starting of horizontal water wheel for pump
Inventor: HAYAKAWA KEIZOU
IPC: F03B15/14
Filed: 1978-03-27
Abstract: PURPOSE: To smoothly push down the water level in a draft tube at the time of starting or water wheel motion phase modifying, by an economic auxiliary appliance  
     CONSTITUTION: To start a horizontal water wheel for a pump, a guide vane 8 is closed and compressed air is introduced from a pipe into the draft tube 5 to push down the water level. When the water level has become 1/2D (D denotes the outlet diameter of a runner 1) from the axis of the water wheel, a water level detector 7 acts to stop introducing the compressed air. Then, the runner 1 is started. At that time, the water level suffers a push-down action but does not perform wave motion due to the rotation of the runner 1 because the water level is away therefrom. As a result, the quantity of the air for pushing down the water level can be minimized and the size of a compressed air unit for supplying the compressed air can be reduced. This leads to the reduction of cost of power plant equipment. When the runner 1 has reached a prescribed speed, water is filled in the draft tube and a guide vane 3 is opened to perform operation.
