Filed: 1980-03-24
Abstract: PURPOSE: To keep control functions at a minimum of demand as to the control of a car engine which uses a microcomputer, by detecting the fault of CPU and by performing switching so that data will be supplied from a part except CPU.  
     CONSTITUTION: According to a program stored in ROM which is not shown in the figure, CPU10 reads input data, and performs arithmetic processing to calculate output data. One means 30 among output means is selected via address bus A 1 , and the output data is supplied from data bus D 1  via change-over means 50. If CPU10 is troubled, fault detecting circuit 40 detects that and outputs change-over signal E. Consequently, circuit 50 performs switching operation automatically to select one of signals D 2 , A 2  and C 2  from data generating circuit 20, and supplies it to circuit 30. As a result, the control is enabled while the minimum operation of demand as to the control precision of a car, the degree of freedom of the control etc., are maintained.

Title: Preparation of passivation film
Inventor: IMAI YUUJI
IPC: H01L21/316
Filed: 1982-03-09
Abstract: PURPOSE:To form a homogeneous film within a short period by forming an Al2O2 film through anode oxidation of Al film formed on an SiO2 film with a constant current power source and by detecting completion of film formation from increase of power supply voltage. CONSTITUTION:An SiO2 film 2 is formed in a wired IC and an Al film 3 is formed thereon. An IC is then dipped into an electrolyte 5, the Al film 3 is used as the anode and an electrode material such as platinum is used as a cathode 4, a constant current power supply 6 and a voltmeter 7 are connected between both electrodes, and thereby a closed loop is formed. At this time, a voltage rises linearly as the Al is oxidized and an Al2O3 is formed. But, when the Al3 is all replaced with an Al2O3, a current path existing between the SiO2 and Al2O3 disappears and a voltage rises rapidly. At this time, supply of power source is stopped, thus completing fabrication. The Al2O3 film becomes homogeneous since the oxidation is carried out by a constant current and fabrication period can be curtailed since the end of process can be detected easily.
