Title: Schottky barrier diode
Inventor: OKAMURA YOSHIO
IPC: H01L29/47
Filed: 1984-01-24
Abstract: PURPOSE:To form a target pattern easily by simultaneously shaping an impurity layer at a position where the target pattern is set when an annular region having a conduction type different from a semiconductor base body is formed on the surface of the base body. CONSTITUTION:An insulating film 13 is formed on the surface of a low-concentration epitaxial layer 12 in a base body in which the layer 12 is grown on an N type high concentration substrate 11. Holes are bored properly to the film 13 while a P type impurity is diffused through the holes to shape an annular P layer 14. Holes are bored previously at the same time at positions where target patterns are set at that time, and P layers 14' are formed. Insulating films 13' are grown so as to coat the upper surfaces of the layers 14', and holes are bored to regions in the layer 14 of the film 13. The films 13' on the layers 14' are left at that time. Barrier forming metals 15 are grown on exposed layers, thus forming a Schottky barrier. The metals 15 are etched, and sections on the films 13' on the layers 14' as the target patterns are removed, thus forming a Schottky barrier diode.

IPC: H03K7/08
Filed: 1980-02-04
Abstract: PURPOSE:To make highly stable the repetitive frequency of output pulse through the detected output, by comparing the detected output of average repetitive frequency of pulse modulating the interval of adjacent pulses with the reference value, and detecting the variance of the average repetitive frequency of the pulse. CONSTITUTION:To detect the variation of repetitive frequency of pulse PIM modulating the interval of adjacent pulses, a smooth circuit 16 is provided. The output of this circuit 16 is compared with a stable reference voltage fixed in advance from a terminal 18 at a differential amplifier 17 for comparison, and the difference is amplified. The output of this amplifier 17 is fed to the input signal from the terminal 11 at a voltage addition circuit 19. As a result, the average level of the input signal is changed, and the average repetitive frequency of the output PIM pulse is changed until the output of the circuit 16 and the reference voltage at the terminal 18 are equal, and it is kept constant when the two are equal. Thus, the repetitive frequency of the output pulse can highly be made stable.

IPC: F02P17/12
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To positively judge the misfire of an engine, using an inexpensive CPU with limited timer function. SOLUTION: Only the active part of a misfire pulse signal is extracted by taking the logical sum of a gate signal 9 from a CPU 1 and a misfire pulse signal 10 by an OR circuit 8, and the free running counter value captured at edge timing of misfire pulse using the DMA function of the CPU 1 is transferred to an RAM 3. Active time of misfire pulse is computed from the difference of the transferred value, and the active time is added and compared with the reference value to judge a misfire. As another method, only the active or nonactive part of misfire pulse during the opened state of a gate is extracted and made into pulse by a reference clock, and the CPU counts the edge number of this pulse to convert it into time and compares it with the reference value.
