Filed: 1986-08-25
Abstract: PURPOSE:To obtain an output signal having a pulse width equal to that of an input signal without increasing the chip area by connecting a specific load externally to an output of an inverter by an odd number stage before an output inverter in a delay integrated circuit comprising plural inverters connected in series. CONSTITUTION:A pulse signal from an FM signal source 17 is delayed by even number of inverters each comprising CMOS transistors (7 and 12, 8 and 13, ...9 and 14, 10 and 15) and outputted to an FM demodulator 18 being a load of the like. A pulse width control circuit 19 for a specific load comprising a series resistor 20 and a capacitor 21 corresponding to the demodulator 18 being the load is connected to the output of the inverter by an odd number just before the final stage. The unsharpened output waveform of the just preceding inverter is adjusted by the specific load and the pulse width decided by the unsharpened waveform over the threshold value is adjusted the same width as that of the input pulse. Thus, it is not required to use the final stage inverter having a large drive capability, and the output signal becomes a signal having an equal pulse width to that of the input signal without increasing the chip area.

Title: Distance measuring apparatus
Inventor: NIIMI HIROSHI
IPC: G01S17/10
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To improve the distance measuring accuracy of a distance measuring apparatus. SOLUTION: In the apparatus which detects the reception of the reflected light of measuring light emitted from a light emitting section 4 by means of a comparator 24 by receiving the reflected light by means of a light receiving section 18 and inputting the light receiving signals to the comparator 24 after amplifying the signals by means of an amplifier 14 and an STC(sensitivity time control) circuit 18, the maximum amplification factor of the amplifier 14 is retrieved (n) times by changing the amplification factor of the amplifier 14 under a condition where noise is not detected erroneously so as to improve the reflected light detecting sensitivity of the device.  Then the minimum amplification factor is selected from the (n) pieces of retrieved maximum amplification factors and the minimum amplification factor is converted into the minimum amplification factor which is obtained when the retrieval is performed (m) times (n<m), and then, the converted amplification factor is set as the amplification factor of the amplifier 14. Therefore, the amplification factor of the amplifier 14 can be set to the optimum number with a less number of retrieving times and the distance measuring accuracy of the distance measuring apparatus can be improved. In addition, the obstacle detection, etc., can be performed excellently by increasing the distance measuring frequency, because the retrieving time can be shortened.

Abstract: PURPOSE:To decrease the distortion of a projected picture even if a picture on a liquid crystal panel is projected with a tilt direction with respect to a screen by providing a picture display panel displaying a picture according to a video signal and a light emission source and making the light incident while the center of the light through the picture display panel is deviated with respect to the center axis of the projecting lens. CONSTITUTION:The light from the light source 1 is transmitted through a condenser lens group 2 and projected to a liquid crystal color display panel 3 controlled by a video signal and on which a picture is displayed from the rear face. Then the lower image of an image A on the liquid crystal color display panel 3 reaches the screen 5 through a focus B of a projecting lens 4 and an optical path D. Further, the upper video reaches the screen 5 through the focus B of the projective lens 4 and the optical path C. Thus, the video image A on the panel 3 is projected to the screen 5 obliquely to form a magnified picture E. Since the radius of the projective lens 4 is larger than the liquid crystal color display panel 3, the collimated ray through the liquid crystal color display panel 3 is all made incident in the projective lens 4 and a bright picture is formed on the screen 5.
