Title: Method and device for active noise elimination and related active noise eliminating device for running vehicle
Inventor: NAKAMURA MITSURU
IPC: F01N1/06
Filed: 1992-08-06
Abstract: PURPOSE:To positively eliminate road noise which arises from a suspension and body vibration when a vehicle runs. CONSTITUTION:Vibration during running is detected by acceleration sensors 1-4 and the detection signals are added in an addition circuit 20 to make up a reference signal 105. The 105 is inputted to a microprocessor 13 via an A/D convertor 12 for applicable signal processing, and then it is outputted as an output control signal 107 and issued in the form of secondary sound from speakers 9-10 via a D/A convertor 14 and a power amplifier 15 to eliminate road noise at the position of microphones 5-8. As the high-coherence reference signal can be supplied in less numbers by adding the plural detection signals, a noise eliminating device can be constructed into a small system.

Filed: 1988-08-26
Abstract: PURPOSE:To attain a high speed in forming an image and to reduce memory elements for image information by dividing an image developing means into two and performing original scanning twice and image developing operation twice so that one color image may be formed. CONSTITUTION:When plural image developing means 2M, 2C, 2Y and 2BK are divided into two and one color image is formed by performing original scanning twice, at the time of performing original scanning by either of the two-divided image developing means, for example, 2Y and 2BK, the other image developing means 2M and 2C are allowed to perform image developing operation. At the time of performing other original scanning by the image developing means 2M and 2C, the image developing means 2Y and 2BK are allowed to perform the image developing operation. Thus, original scanning is performed twice very time one color image is formed, so that the number of the memory elements for image information can be reduced while keeping an image forming speed high.

Title: 50% duty ratio correction circuit
Inventor: ABE KAZUNARI
IPC: H03K5/00
Filed: 1990-08-10
Abstract: PURPOSE:To obtain an uncontrolled 50% duty ratio correction circuit by adding a phase comparator, loop filter and operational amplifier to a circuit which multiplies an input signal after dividing the frequency into two stages. CONSTITUTION:An input signal 1 is turned to a frequency two-demultiplier output signal 3 after dividing the frequency into two stages by a 1/2 frequency divider 2. A delay line 4 delays this signal 3 and prepares a delay signal 8. An exclusive OR gate 10 extracts an output signal 11 from the signals 3 and 8, and a loop filter 9 integrates the output signal 11 and outputs an integration signal 7 so that a potential can be VDD/ 2 in the state of setting the 50% duty ratio of the output signal 11. When the duty ratio of the output signal 11 is deviated from 50%, an operational amplifier 6 controls a delay line control signal 5 so that the potential of the integration signal 7 can be VDD/2, and therefore, the delay amount of the delay line 4 is controlled so as to set the duty ratio of the output signal 11 at 50%. Thus, the 50% duty ratio correction circuit can be obtained without controlling the delay amount.

IPC: H02J3/18
Filed: 1987-08-26
Abstract: PURPOSE:To perform the control which is easy to set and uses capacitors different in capacity, by operating the making level and the breaking level based on the set value of a setting means. CONSTITUTION:A CPU 102 reads in the measured reactive power value detected by a reactive power detecting part 101 and operates the reactive power value based on this value. A control signal output means outputs a make control signal if the reactive power exceeds the making level, and the control signal output means outputs a break control signal if the reactive power exceeds the breaking level. A selecting means selects capacitors to by opened or closed by the cyclic control if respective capacitors have the same capacity, but the selecting means selects them by the precedence control if they are different in capacity. Capacitors which should be made or broken out of capacitors 62a, 62b, and 62c are determined by the signal from a relay control part 107. Thus, the change of the set value or the like is facilitated and the control using capacitors different in capacity is possible.
