Then, a silicon oxide film 2 is etched. In this state, all the surface of a substrate is nitrided, a silicon nitride film 12 as thick as 4 to 5 nm is formed only in a region where a transistor is to be formed. Then, a plasmatic vapor silicon oxide film 62 is deposited on all the surface of the substrate. Thereafter, all the substrate is etched back to make all its surface completely flat. At this point, an element region is covered with the silicon nitride film 12, so that the element region is kept free from damage caused by plasma. Thereafter, the silicon nitride film 12 is separated off, and thus the element isolation region is completely flattened.

Abstract: PURPOSE:To precisely obtain the distance information of a near target and the distance and speed information of a far target by providing a transmission section transmitting the FM-modulated carrier wave. CONSTITUTION:A voltage-controlled oscillator VCO oscillates the carrier wave with the preset frequency, and it is FM-modulated with a triangular wave. The modulated carrier wave is transmitted to the front of a vehicle as a transmitted wave T, a reflected wave R from a target is received, it is homodyne- detected by a mixer MIX, then a beam signal IF with the beam frequency of the distance and speed of the target is obtained. The beam signal IF is inputted to two kinds of band-pass filters BPF1, BPF2, and their outputs are amplified by amplifiers A1, A2 and converted into pulses by pulsing circuits B1, B2. The gain of the amplifier A1 for the far target is set higher than the gain of the amplifier A2 for the near target. An MPU calculates the distance of the near target based on the output of B2 pulsed from the output of BPF2 for the near distance when the frequency of the triangular wave is high, and it calculates the distance and speed of the far target based on the output of B1 pulsed from the output of BPF1 for the far distance when the frequency of the triangular wave is low.

Filed: 1987-10-20
Abstract: PURPOSE:To eliminate detection in a range in which image information processing is not influenced and to execute the effective detection by detecting a PLL error when the number of phase error signal in the scanning period of the 1 line of a scanned body exceeds a prescribed value set beforehand. CONSTITUTION:A phase difference output pulse PO from a PLL circuit is inputted to an AND circuit 50 along with a clock signal CLK. A counter circuit 52 calculates the number of output pulses and detects the pulse width of the pulse PO. A comparing means 54 compares the pulse width with the setting value of a constant setting circuit, and the means outputs a phase error signal when the pulse width is larger than the setting value. The signal is inputted to a calculating means 58 to be cleared by a line clock LCLK. The calculating value of the means 58 is compared with the setting value of a constant setting circuit 62, a PLL error signal PE is generated when the calculating value, namely, the phase error signal frequency generated in the scanning period of the 1 line of an accumulating character fluorescent material sheet goes to the setting value or above, and the signal is supplied to an image signal processing part. Consequently, even when the phase error signal is generated in the range not to influence the processing, the PLL error is not detected.
