    摘要： A vibration damper for detecting vibrations of break pads and vibrating the pads in such a way as to damp the vibrations detected. The damper has the function of adjusting control constants for a control circuit according to the degree of deterioration with time, of the pads due to wear so that vibrations of the pads can be damped in an optimum manner. A vibration detector means detects frictional vibrations of the pads and the disk rotor. A control signal corresponding to the detected vibration frequency is applied to a vibrator means through a control circuit. When an input signal for correction timing is inputted from an ignition switch, a signal generator transmits a signal having a predetermined frequency to the vibrator means. The resulting vibration is detected by a signal detector. Based on the detection signal, transfer functions for the control circuit are adjusted to suppress vibrations having squealing frequencies.

    摘要： A vibration damper can suppress squeals of a brake in a positive and reliable manner while consuming less electric power. The damper has a vibration detector for detecting vibrations of the brake, and a vibrator for applying vibrations to the brake pad based on a detection signal from the vibration detector. An actuator circuit for actuating the vibration detector and vibrator is connected to a car battery through a changeover switch and another switch. These switches are closed only if a brake switch is detecting that the brake is being applied and a vehicle stop detector is detecting that the vehicle is not moving. When the switches are closed, electricity is supplied to the actuator circuit, so that the vibration detector and vibrator are actuated by the actuator circuit. With this arrangement, the damper is kept deactivated when it is unnecessary or detrimental to apply vibrations to the brake. Since it is activated only when necessary, it consumes less electric power.

    摘要： A vibration damping mechanism for use in a disc brake which can effectively suppress squeaks of the disc brake during braking. Vibrations of the rotor are detected by a piezoelectric element pressed against the back of an inner pad. The detection signal is inputted in a control circuit. The control circuit applies a control signal to another piezoelectric element which produces oscillations having a frequency that can reduce the detection signal to zero. The oscillations produced by the piezoelectric element are transmitted to the rotor to cancel the vibrations of the rotor. With this arrangement, signal components other than the rotor vibrations are scarcely contained in the detection signal, so that it is possible to produce oscillations that can cancel vibrations of the rotor with high accuracy. As a result, the rotor vibrations and thus squeaks of the disc brake are effectively suppressed.

    摘要： A is a vibration damper suppresses squeaks of a disk brake by positively damping vibrations of the brake. It is a high-performance, highly reliable vibration damper with no accurate machining required. This vibration damper has pressing pistons received in brake pistons so that brake fluid pressure acts thereon. It further includes a vibration detector for detecting brake vibrations through one of two pads, and a vibration imparter for vibrating the other pad based on detection signals of the vibration detector so as to cancel out the vibrations detected by the vibration detector. They are pressed against the back of the respective pads by the respective pressing pistons. By pressing them at a suitable pressure against the pads, it is possible to detect vibrations and vibrate the pads with high reliability. When replacing the pads, they never protrude from the pad pressing surfaces, so that they are less likely to be damaged or destroyed.

    摘要： A video IF signal detector includes a first phase detector detecting a phase difference between an input video IF a signal and a first reference signal. A low pass filter acts on an output signal from the first phase detector. A VCO generates the first reference signal and a second reference signal in response to an output signal from the low pass filter. The first reference signal and the second reference signal have a fixed phase relation with each other. The first phase detector, the low pass filter, and the VCO compose a PLL. A second phase detector detects a phase difference between the input vido IF signal and the second reference signal and extracts a baseband video signal from the input video IF signal. The PLL is enabled during a first period where the input video IF signal is independent of display information. The PLL is disabled during a second period where the input video IF signal represents the display information.

    摘要： In order to effectively damp the vibration of the drum of a drum brake, which is a main cause of brake squeals, a vibration detector and a vibrator are provided and operated separately from each other. The vibration damping control is carried out directly mechanically, or in a non-contact manner to improve durability of the device. A piezoelectric element, magnetic sensor or acceleration sensor is used to detect the vibration of the drum. The detected vibration is converted to an electric signal. After adjusting its phase and amplitude, the electric signal is converted to vibration force and outputted through a piezoelectric element or magnetic actuator as the vibrator to suppress brake squeals.
