IPC: H04L27/36
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To improve the modulation accuracy of the output signals of a quadrature modulator, to reduce the influence of element dispersion when being made into an IC and to improve a yield. SOLUTION: This quadrature modulator is provided with bias correction circuits 21 and 22 for detecting an offset voltage generated by the variations of elements for constituting a circuit and unrequired signals in quadrature modulator output, etc., and automatically adjusting bias, based on them.

Abstract: PURPOSE:To prevent overheating in a liquid by paralleling the direction of a line connecting both electrodes of a detecting element consisting of a positive characteristic thermistor to a liquid level and making it possible to indicate a continuous change of the liquid level with simple constitution. CONSTITUTION:When the whole of the long-sized detecting element 6 consisting of the positive characteristic thermistor is in the air, the heat dissipation coefficient is reduced and the element 6 generates heat for itself and attains thermal equilibrium with high temperature. On the other hand, the resistance of the element 6 is reduced when the whole element 6 is in gasoline.

The change of the liquid level can be continuously indicated by reading the change of the electric current. In this case, the element 6 is fixed so that the direction of the line connecting the electrodes 7 provided to both main surfaces of the thermistor is paralleled to the liquid level.

Title: Air-fuel ratio control method for internal-combustion engine
Inventor: SUEMATSU TOSHIO
IPC: F02D41/14
Filed: 1983-01-14
Abstract: PURPOSE:To detect abnormality of sensor by performing air-fuel ratio control while accumulating the lean signal generating time under feedback control region while holding the accumulated level under non-feedback region and performing same air-fuel ratio control with non-feedback upon exceeding over predetermined level. CONSTITUTION:When engine load enters into feedback control region, a controller 44 comprising a microcomputer will accumulate the lean signal generating time from O2 sensor 30 in RAM and hold said accumulated level in such region where feedback through O2 sensor 30 is not performed. When said accumulated level has exceeded over predetermined level during feedback control, it will perform air-fuel ratio control with predetermined air-fuel ratio similarly with non-feedback region irrespective of the output from O2 sensor and reset the accumulated level exceeding over predetermined level through an output from O2 sensor indicating that the air-fuel is over rich. Consequently even if O2 sensor output is abnormal under operating state repeating feedback and non-feedback region, abnormality can be detected reliably and upon continuation of abnormality over predetermined time, it can be transferred to non-feedback control.

Title: Speedometer for automobile
Inventor: MATSUMOTO KATSUI
IPC: G01P3/44
Filed: 1979-01-18
Abstract: PURPOSE: To compensate the difference between the rotational frequency of a wheel and a real speed relative to the ground, due to the racing of the wheel caused with the slip of its tire and raise the accuracy when pulse signals produced by a vehicle speed sensor within the period of a reference signal are sequentially counted to digitally indicate the vehicle speed.  
     CONSTITUTION: Pulse signals (a) produced by a vehicle speed sensor 1 and proportional to the rotational frequency of a wheel are counted by a counter 3 in every period of a signal (b) produced by a reference signal generator 9. The value counted by the counter 3 in each period of the signal is held in a latch circuit 4. The speed of a vehicle is digitally displayed by an indicator through a decoder driver 5. When the value counted by the counter reaches a compensation starting vehicle speed set in a vehicle speed setting circuit 7 during the process of the counting, the oscillation constant of the generator 9 is altered to shorten the period of the signal. As a result, the detection error of the vehicle speed due to the racing of the wheel in rapid running is compensated to indicate a more accurate vehicle speed approximate to the real velocity relative to the ground.

Title: Liquid developing method for electrophotographic film
Inventor: KIMURA AKIFUMI
IPC: G03G15/10
Filed: 1986-01-14
Abstract: PURPOSE:To equalize the image density of the part of a half solid and to improve a fine line reproducibility by switching a bias voltage to the voltage of the polarity reverse to the charging polarity or the lower voltage which is the same polarity, at least one time. CONSTITUTION:The bias voltage is switched to the voltage of the polarity reverse to the charging polarity only during the comparatively short time at least one time or is switched to the lower voltage of the same polarity as the charging polarity. At the initial time of developing, an electric field strength Ez comes to be the distribution in accordance with the solid image, the toner concentration shows the trend to deviate to a developing electrode 96 side at a background part (a), and therefore, the strength receives a large influence and comes to be the distribution to deviate to a developing electrode 24 side at a half solid latent image upstream part (b). Since the time to lower the bias voltage is the shorter time than the time when the toner concentration distribution is changed, fogging is not frequently increased. Thus, since the sticking quantity of the toner particles is prevented from being little at the upstream part (a) of the half solid, the image density of the part of the half solid becomes uniform.
