Abstract: PURPOSE:To easily set the duty ratio from 0% to 100%. CONSTITUTION:A pulse width modulating device 30 consists of a counting circuit 32 which outputs an overflow signal at the tinge of return from the final value to the initial value, a comparing circuit 34 provided with a comparator 35 which compares a counted value N from the counting circuit with a duty value (m) stored in a register 36 and outputs a coincidence signal at the time of coincidence between them and a zero detector 38 which outputs the coincidence signal at the time of detecting that the duty value in the register is 0, and a pulse width modulation signal output circuit 42 which inverts the value of a binary output pulse signal in response to the overflow signal and the coincidence signal to output the pulse width modulation signal which has the duty ratio corresponding to the duty value, and a preset device 46 is provided which writes a preliminarily designated value in the counting circuit and forces the counting circuit to count the value from the designated value to the final value. When 100% duty ratio is written, the output pulse does not drop to '0' in the last part.

Title: Information signal reproducting method
Inventor: ABE MICHIHARU
IPC: G11B27/36
Filed: 1986-04-30
Abstract: PURPOSE:To reduce effectively a bit location deviation due to the asymmetry by arranging plural circuit means detecting a means value of input signals and controlling the amplitude to make the highest and the lowest values of the mean values equal to each other in series, inputting the detection signal by a photodetector to an arrays of the amplitude control circuit and repeating the processing of amplitude limit by the number of circuit means. CONSTITUTION:n-Set of amplitude limit circuits C1-Cn are identical and when a signal is inputted to an input terminal PI, the signal passes first through a low pass filter having a time constant C1R1, is amplified inversly by an operational amplifier A whose amplification factor R2/R1 and the amplitude is limited by a resistor R3 and diodes D1, D2. Thus, the ground level is used as the means value and the highest and lowest mean values are made equal by the amplitude limit, the signal processed as above is obtained from an output terminal P0. Every time the amplitude limit processing by the amplitude limit circuits is repeated, the mean value is always moved to reduce the asymmetry. Thus, as the amplitude limit processing is being repeated, the asymmetry is reduced sequentially.

Title: Detecting method for descending slope traveling
Inventor: NISHINO HARUHIKO
IPC: F02D45/00
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To make descending slope traveling possible without using a grade sensor by detecting the total quantity within a prescribed time of fuel supplied during traveling on an about flat road as a fuel quantity during descending slope traveling in the case where the actual fuel supply quantity satisfies prescribed conditions to a reference total supply quantity computed at least on a vehicle speed. SOLUTION: An electronic controller 6 determines a basic injection time on each of output signals sent from a throttle sensor 16 and a cam position sensor 14, and the basic injection time is usually corrected by feedback-control on an output signal (h) sent from a O2 sensor to determine effective injection time. In addition, the total quantity within a prescribed time of fuel supplied to an engine 100 during traveling on an about flat road is computed as the reference total supply quantity at least based on a vehicle speed, and the total quantity of fuel actually supplied within a prescribed time is computed as the total actual supply quantity. As result of the reduction of reference integrated value from actual integrated value, the traveling is judged as the descending slope traveling in the case where the actual integrated value is less than the reference integrated value.

Abstract: PURPOSE:To eliminate the effect of illumination variance and output variance of an image pickup element, and to obtain the accurate picture information, by reading successively the video signals equivalent to two scan lines to discriminate plural pictures contained in an object to be measured, and measuring the complexity of each picture with a small quantity of picture data. CONSTITUTION:An object 1 to be measured is shifted by an automatic feed mechanism 8 while the focal position of the object 1 is controlled. Then the pictures are read by a line scan type solid-state image pickup element 3 through an optical system 2. This read picture signal is applied with A/D conversion through an output spot correcting part 4 and is corrected by the reference data measured previously. A measurement circuit 5 measures the parameters such as the size, form, color, etc. of the picture groups contained in the corrected video signal. Then the result of this measurement is displayed at a display part 6. Each of these parts is controlled with the timing output a control part 9. While the system 2 is controlled by an automatic focusing mechanism 7, and the complexity of each picture is measured with a small quantity of data. Thus the effects of the illumination variance and the output level variance of the element 3 are eliminated to output the accurate picture information.

Filed: 1979-08-10
Abstract: PURPOSE: To improve operating characteristics by providing shielding members for shielding the incidence to the semiconductor parts in a liquid crystal display cell provided with semiconductor driving circuits on a display substrate.  
     CONSTITUTION: Since the display device is of passive type, there is need for irradiating the display surface by external light, but since semiconductors such as CdS, CdSe as materials for thin film transistors for driving have marked photoconductivity, the operating characteristics become unstable. Thereupon, when the incident direction of external light is above the substrate 7, light shielding members 6, 6' are provided on the semiconductor parts. Here, the installing members of the light shielding members may be changed variously depending upon whether the display cell is used in projection type, transmission type or reflection type. The light sheilding members 6, 6' which have good color absorptivity of black or dark colors and do not cause chemical reaction with the liquid crystal layer 11 and semiconductors 2, 2' are desirable. In this way, the operating characteristics may be improved.

Abstract: PROBLEM TO BE SOLVED: To enable elimination of effects of common mode noise due to capacitive coupling, by a constitution to obtain a measurement signal from which a common mode noise current mixed in via the stray capacitive coupling of an insulating part is eliminated form an operational amplifier. SOLUTION: In the case that high-frequency common mode noise Vcom is mixed in an input signal Vin, a common noise current Icom is mixed in a photodiode current Ipd2 on the output side, which is the original circuit current of a measurement signal, by electrostatic coupling due to stray capacitance CS between the input and output of an analogue insulation IC 50 to flow a current of Ipd2 +Icom. Therefore, a signal containing a noise voltage Vn in an output signal Vout is outputted.  It is possible to implement the elimination of the noise voltage Vn due to the common mode noise current loom by flowing a noise cancel current Ican, which is regulated so as to cancel out the common mode noise current Icom added to the photodiode Ipd2 on the output side by a common mode noise cancel circuit 40 to flow, through the non-inverting input terminal of the operational amplifier A2 on the output side.
