Title: Automatic clock duty adjusting circuit
Inventor: SAKAMOTO TAKASHI
IPC: H03K5/04
Filed: 1989-06-23
Abstract: PURPOSE:To output the clock of a prescribed duty by sampling a signal from each output tap of a delay line, measuring the clock duty and executing a duty adjustment. CONSTITUTION:Each signal outputted from the output tap of a delay line 2-3 is used as the clock of each corresponding flip-flop of a flip-flop group 3, and the clock to be properly delayed by using an output clock 15 delay buffer 7 is sampled at the accuracy of the intertap delay time of the delay line 2-3. A clock duty calculation arithmetic circuit 5 outputs an 'H' level width signal 16 and an 'L' level width signal 17 to a clock duty selection instructing circuit 6. The clock duty selection instructing circuit 6 outputs a clock duty selection instructing signal 14 to a clock duty adjusting circuit 1 so as to reduce the difference between the widths of the 'L' level and 'H' level. By repeating the above-mentioned actions, the output clock duty is fixed.

Title: Current detector for control load and failure diagnostic unit employing it
Inventor: INA HIROYUKI
IPC: G01N27/12
Filed: 1993-06-30
Abstract: PURPOSE:To enhance the current detection accuracy of a current detector and the abnormality detection accuracy of a failure diagnostic unit employing it. CONSTITUTION:Current flowing through the heater 2 in an oxygen sensor 1 is detected by a current detection resistor 5 in the form of a voltage and amplified by means of a differential amplifier circuit 6 before it is converted into a digital value through an A/D converter 13. The A/D converter 13 provides a reference voltage VC for the differential amplifier circuit 6 as reference of the amplification. Resistors 8-11 constituting the amplifier circuit 6 have resistances being set so that (R1/R2)<(R3/R4) and thereby, the output voltage VOUT comes within the processing range of the A/D converter 13 when the heater 2 is not conducting. A microcomputor 14 updates the offset voltage based on the output voltage VOUT every time when the heater 2 is not conducting. When the heater 2 is conducted, the microcomputor 14 calculates the heater current iH using the offset voltage and judges the heater 2 to be abnormal.

Title: Sink control circuit and digital signal reproducing device
Inventor: NOCHIDA KAORU
IPC: H04N5/92
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To compensate a sink pulse without following to an input pseudo sink signal. SOLUTION: The circuit is provided with a gate means 76 with respect to sink pulses received at a prescribed clock interval and a sink delay means 72 delaying a gated sink pulse SL0 by the sink pulse interval. A delay means 72 is made up of a counter 81 counting a clock signal, a gate pulse generating means 84 generating a gate pulse based on the counter output, a detection means 82 detecting the prescribed count of a counter output and a flip-flop 83. The gate pulse generating means generates a gate pulse GA1 not getting through the gate other than the case when a counter output is zero. Thus, since the delay means 72 is not operated by a pseudo pulse intruded between the sink pulses, only the correct sink pulse is delayed and outputted.

Title: Automatic dimming device for endoscope using liquid crystal filter
Inventor: NAGASAKI TATSUO
IPC: G02B23/24
Filed: 1983-09-05
Abstract: PURPOSE:To dim automatically illuminating light to the illuminating light suitable for observation and to eliminate the need for a dimming operation by adjusting the intensity of illumination to an object by using a liquid crystal filter in accordance with the signal corresponding to the quantity of light outputted from photodetectors. CONSTITUTION:The illuminating light of a lamp 16 for illumination passes through the light transmitting part of a liquid crystal filter 20 and is irradiated from the exit end at the top end of a light guide 13 thereby illuminating an object. The light reflected by the object is detected by the photodetectors of a solid state image sensing element 4. The signal converted to an electric signal is read out with a clock signal and after the signal is amplified by a preamplifier 5 and color amplifiers 7R, 7G, 7B, the signal is displayed on a color cathode ray tube 12 for monitor. If the intensity of the illumination is too high in this case, the level of the signal outputted from the photodetectors of the element 4 increases and therefore the light shielding area of the filter 20 is increased according to the magnitude of said level, by which the intensity of the illuminating light illuminating the affected part is decreased via the guide 13.
