IPC: H01J1/15
Filed: 1979-07-18
Abstract: PURPOSE:To prevent the exfoliation of an oxide film for langthening the longevity of a directly heating type cathode by roughening the surface, where an alkaline earth metal oxide is to be coated, of a base by providing finely concaved portions. CONSTITUTION:The upside of the base 1 is roughened by integrally providing a great number of finely concave portions 1a, and then the roughened surface is coated with alkaline earth metal oxide 2 to form a cathode. In this case, both sides of the base 1 are coated with a photoresisto, exposed to light through a desired pattern of a negative film, developed, and then subjected to an etching treatment using an acid in order to form finely concaved portions 1a on the upside of the base 1. Then, the remaining photoresisto is removed out to obtain a desirably formed rough surface only on the upside of the base 1. Thus, the exfoliation of the alkaline earth metal oxide can be exactly prevent because the surface to be coated with the alkaline earth metal oxide 2 is securely roughened, and therefore the longevity of the cathode can be lengthened and its reliability can be also raised.

Title: Catalyst deterioration detection apparatus
Inventor: YASUNAGA HISAYO
IPC: F02D41/22
Filed: 1991-04-22
Abstract: PURPOSE:To detect the catalyst deterioration with high accuracy even when the characteristics of an upstream side oxygen sensor are deteriorated, by providing the apparatus with air-fuel ratio correction coefficient calculation means and with delay time length detection means for detecting a delay time length extending up to the occurrence of a change in the output signal from a downstream side oxygen sensor. CONSTITUTION:An upstream side oxygen sensor is disposed at a position upstream from a catalyst section for purifying an exhaust gas, which catalyst section is disposed in an exhaust system of an engine. An air-fuel ratio correction coefficient calculation means calculates an air-fuel ratio correction coefficient for correcting the air-fuel ratio in an air-fuel mixture supplied to an engine in accordance with an output signal from the upstream side oxygen sensor so as to cause it to become approximately a theoretical air-fuel ratio. Delay time length calculation means calculates a delay time length covering from a specified change in the air-fuel ratio correction coefficiency to a change in the downstream side oxygen sensor output corresponding to that specified change. Thus, the catalyst deterioration is so decided by catalyst deterioration detection means when the delay time length has become shorter than a specified time length.

Title: System for guaranteeing readout of data in file memory
Inventor: NARIAI IZUMI
IPC: H04M3/24
Filed: 1988-04-15
Abstract: PURPOSE:To improve the reliability of a system by preventing abnormal influence due to erroneous readout data from being given by attaching address data on storage data in a file memory as check information, and collating with address check information attached on readout data. CONSTITUTION:A write address (FMA+J) is calculated by extracting a memory address FMA by indexing a file memory address managing table 6 by designation information 1, and adding file memory designation information J. And address information corresponding to write data DATA(I, J) in one to one is attached on the write data DATA(I, J). Next, file memory data 7 at the address is read out by extracting the file memory address FMA by indexing the file memory address managing table 6 by the designation information I, and next, check information 8 attached on the readout data is extracted. And it is collated with a designated address. When coincidence is obtained as a result of collation, it is judged that targeted data is read out of a normal address, and a processing is completed normally. When noncoincidence is obtained, it is assumed that a read address fault has been generated in the readout operation of the file memory, then, the processing is shifted to an error processing.

Title: Circuit device for temperature detection of semiconductor element for electric power
Inventor: YOOZEFUUMACHIASU GANCHIOORAA
IPC: G01K7/01
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To positively detect a temperature which is lower than a specific temperature by supplying the off current of a bipolar semiconductor element (transistor) to an amplification-type current mirror circuit. SOLUTION: A bipolar transistor 1 is connected to an input terminal 4 of an amplification-type current mirror circuit consisting of MOSFETs 2 and 3 and MOSFETs 6 and 7. An off current corresponding to the temperature flows through the transistor 1 and the off current is supplied to the mirror circuits 2 and 3. The potential of a terminal 10, for example, a potential positioned at a zero potential is fed to an output terminal 14. It is so designed that a current passing through an output terminal B is larger than the maximum current of an FET 12 at a temperature which is lower than the maximum allowable temperature. In this case, a voltage which is equal to a value obtained by subtracting a voltage between the drain and source of the FET 7 from + UBB is generated at an output terminal 14.  The increased voltage between the output terminal 14 and the terminal 10 is detected as a temperature which is lower than the critical one, for example, the temperature increase toward 140 deg.C.
