    • An electromagnetic proximity sensor for car security systems includes an electromagnetic wave radiating section adapted to oscillate in a predetermined high frequency range to outwardly radiate an electromagnetic wave; a clutter component extractor for extracting a low frequency clutter component generated in the electromagnetic wave by the approach or movement of an object; a level comparing section, to which is supplied a low frequency clutter component signal corresponding to the extracted low frequency clutter component so as to be compared with a predetermined reference level and which is adapted to emit a sensor signal when the clutter component signal supplied is beyond a predetermined level; and an oscillating operation intermitting section, to which is supplied a pulse signal of a variable duty ratio and of a frequency higher than that of the low frequency clutter component and which is adapted to intermit the oscillating operation of the electromagnetic wave radiating section on the basis of this pulse signal. The electromagnetic proximity sensor may also include a reference level generating section, to which is supplied a pulse signal of a variable duty ratio and which generates a reference level voltage adapted to change its level in accordance with the duty ratio of the pulse signal and supplies it to the level comparing section.

    • An inclination detector is constructed such that a displacement detection plate of generally fan-shape is pivotally supported at its fan-pivot, a plurality of slits are formed in the displacement detection plate concentrically of the fan-pivot at predetermined intervals, and a light emitting element and a light sensitive element constituting a photocoupler are disposed on opposite sides of the displacement detection plate with the slits interposed therebetween, whereby when a slit is caused to move due to a vibration or slant and traverse the optical path of the photocoupler, a displacement of the slit due to the vibration or slant is outputted from the light sensitive element.
    • 倾斜检测器被构造成使得通常扇形的位移检测板在其风扇枢轴处枢转地支撑,在位移检测板中以预定间隔与风扇枢轴同心地形成多个狭缝,并且发光 元件和构成光电耦合器的感光元件设置在位移检测板的相对两侧,其间插入狭缝,由此当狭缝由于振动或倾斜而移动并穿过光电耦合器的光路时,位移 从光敏元件输出由于振动或倾斜引起的狭缝。
