Title: Fault detection system for a/d converter
Inventor: MUKUDA YOJI
IPC: H03M1/12
Filed: 1992-12-14
Abstract: PURPOSE:To prevent mis-detection or deterioration in conversion accuracy due to a transient external disturbance such as noise by comparing a mean value of plural conversion values with a reference value and detecting it to be the occurrence of a fault when a difference is larger than a preset allowable value. CONSTITUTION:A mean value of data for number of times to be stacked is calculated (step 205) and an error is obtained from a difference between the mean value and an ideal reference voltage Vref (step 206). The obtained error and the preset allowable value are compared (step 207), and when the error is less than the allowable value, it is discriminated that an A/D converter is normal and the error is set as a correction value (step 209). However, when the error is larger than the allowable value (step 206), it is discriminated that the A/D converter has a fault (step 210), and data of the cycle are disregarded. Then the processing is returned to a step of the analog signal input selection (201). Thus, a host device using a conversion output uses a preceding conversion value and malfunction due to a transient noise or the like is prevented.

Abstract: PURPOSE:To obtain a semiconductor circuit whose response speed is increased by setting the level of a data signal line to a predetermined specific value and inverting and outputting the level of the specific value according to a clock signal when a specific data signal is transmitted to the data signal line. CONSTITUTION:When an address signal inputted to an AND gate 23a enters an all-H-level state, the output of an output buffer 26a goes up to an H level.

Filed: 1987-12-29
Abstract: PURPOSE:To give a suitable gamma correction to a video signal for driving a liquid crystal display device by operating a level shifting circuit, when the voltage of an input signal exists between two reference voltages. CONSTITUTION:When the voltage of an input terminal 3 is lower enough than reference voltages V11, V12, a level shifting circuit does not operate. As said voltage approaches the reference voltage V11, a current flowing through current mirror circuits Q13, Q12 increases, and at the time of V11<(the voltage of the input terminal)<V12, the voltage of an output terminal 4 approaches +I12.R11 and raised suddenly. When said voltage approaches the reference voltage V12, a voltage difference between the output terminal 4 and the emitter of a transistor Q11 decreases, and also, when the voltage of the input terminal 3 becomes larger enough than the reference voltage V12, the output terminal 4 becomes the same voltage as the transistor Q11. In such a way, a gamma correction characteristic which is required for a video signal for driving a liquid crystal display device can be satisfied.

Filed: 1994-12-19
Abstract: PURPOSE:To suppress adverse effect of a through hole for caulking on a motor by making the through hole for caulking on the inside of a hole for inserting a magnetic body constituting a pole and deviating the through hole from a magnetic path formed across adjacent poles thereby preventing the magnetic resistance from increasing. CONSTITUTION:A plurality of iron plates 27 for rotor are laminated, rivets are inserted into respective through holes 47-50 and then the laminate is caulked integrally along with a end face member thus constituting a rotor core 26. The through holes 47-50 are made on the inside of respective magnetic bodies 45 at the peripheral part of a magnetic path formed between the adjacent magnetic bodies 45 so that the through holes do not contribute to the magnetic resistance of the magnetic path. Since the caulking parts 56-59 for securing the iron plates 27 mutually and the holes 61-64 for oil path are extremely small gaps as compared with the through holes 47-50, influence thereof on the magnetic field is low. This structure enhances the motor output while minimizing adverse effect of the through holes 47-50 on the motor.

IPC: H01L29/861
Filed: 1993-12-28
Abstract: PURPOSE:To obtain soft-recovery characteristics by reducing the reverse recovery charge and forward voltage in a semiconductor device such as diode. CONSTITUTION:The surface impurity concentration of a P-type diffusion layer 12 is in the range between 1X10<15>cm<-3> and 1X10<17>cm<-3>, and the thickness of the P-type diffusion layer 12 is in the range between 0.1mu and 3.0mum. Therefore, the value of the concentration of the surface impurity is low so that the implantation of minority carriers from the P-type diffusion layer 12 to an N-type semiconductor substrate 11 is suppressed at the time of forward operation to reduce recovery charges. The thickness of the P-type diffusion 12 is thin so the reverse recovery charges are further reduced to reduce the forward voltage, together with the reduction in the reverse recovery charges, the peak of the reverse recovery current is reduced, resulting in that the soft recovery is achieved, thereby reducing the surge voltage.
