An object detecting device can prevent a seizure of an object between an opening and an opening-closing unit for opening and closing the opening. The object detecting device includes a pressure-sensitive sensor disposed at one of the opening and the opening-closing unit, and judging means for judging the contact of the object with the pressure-sensitive sensor on the basis of an output signal of the pressure-sensitive sensor. The pressure-sensitive sensor includes pressure-sensitive means for generating an output signal depending on deformation, and support means for supporting the pressure-sensitive means at the one of the opening and the opening-closing unit, the support means including a vibration damping portion for damping vibration propagated to the pressure-sensitive means.

Pressure-sensitive sensor, object detecting device, and opening-closing device

In a pressure-sensitive sensor for detecting seizure of an object in the window frame or the like, support means ( ) is more flexible than a piezoelectric sensor ( ), and the support means ( ) is easily deformed together with the piezoelectric sensor ( ) without impeding the deformation of the piezoelectric sensor ( ), and an output signal is issued from the piezoelectric sensor ( ) depending on this deformation. Accordingly, when detecting the contact of an object with a pressure-sensitive sensor ( ) by a judging device, the pressure-sensitive sensor ( ) for generating an output signal of a sufficient magnitude for detection can be presented.

A polarization apparatus is provided wherein a piezoelectric body tube is wound around a first rotation drum and a second rotation drum and a coaxial flexible piezoelectric body is polarized while the piezoelectric body tube is wound. According to the polarization apparatus, polarization can be conducted except for the coaxial flexible piezoelectric body of the portion containing a defect and a defect existing in the piezoelectric body tube of a given length can also be detected before an outer electrode is formed.

A signal processing apparatus for use in a video cassette recorder comprising a pilot burst gate pulse generating system means responsive to horizontal synchronizing signals successively generated in correspondance with horizontal scanning periods to process the horizontal synchronizing signals so as to produce pilot burst gate pulses. The pilot burst gate pulse generating system is responsive to a first horizontal synchronizing signal to generate the pilot burst gate pulse at a timing delayed by a predetemined time period from a leading edge of a second horizontal synchronizing signal following the first horizontal synchronizing signal. This arrangement allows stable generation of the pilot burst gate pulse at a timing slightly delayed from the active edge of the corresponding horizontal synchronizing signal.

A video signal processing apparatus has a phase-locked loop which includes a quartz resonator, a voltage-controlled oscillator connected to the quartz resonator and oscillating at an oscillation frequency whose fundamental value is determined by the quartz resonator, and a horizontal sync signal lock circuit comparing a phase of a horizontal sync signal and a phase of an output signal from the voltage-controlled oscillator and controlling the oscillation frequency of the voltage-controlled oscillator in response to a difference between the phases of the horizontal sync signal and the output signal from the voltage-controlled oscillator. The video signal processing apparatus also has a device for modulating a video signal by use of the output signal from the voltage-controlled oscillator.
