摘要： A pyroelectric-type IR receiving element comprises a pyroelectric substrate which is fixed to a supporting body at its support ends and at least one rectangular patch formed in the substrate. The patch is formed on its opposite surfaces with first and second electrodes which are overlapped to each other. The substrate has a U-shaped slit composed of a pair of side slits and a base slit connecting the side slits. The U-shaped slit surrounds continuously three sides of the patch, so that the patch is supported by the substrate in a cantilever fashion at a cantilever end which is opposed to one of the support ends of the substrate. Since a thermal stress applied to the substrate when the substrate is exposed to a temperature change is absorbed by the U-shaped slit, a stress concentration to be considered is not developed in the patch. As a result, it is possible to reduce the occurrence of popcorn noise, while maintaining good IR sensitivity.

摘要： A method of producing plural device chips from a thin plate of a pyroelectric material comprises the following steps. First, plural device-forming regions each having an electrode and a circuit pattern for electrically connecting the electrodes are formed on each of front and rear surfaces of the thin plate to obtain a device substrate. By making an electrical connection between the circuit patterns, and grounding it, all of the device-forming regions on the device substrate are at the same potential. Next, a blast treatment is performed to the device substrate to remove a required region of the pyroelectric material, while leaving a bridge portion extending between adjacent device-forming regions and having the circuit patterns thereon, so that a device-chip aggregate is formed, in which adjacent device chips are coupled through the bridge portion. Subsequently, by removing the bridge portion, the device chip is separated from the device-chip aggregate.

摘要： An image processor is provided, which has the capability of detecting an object such as a human face from an image taken against the sun with high accuracy. An image signal provided from an image pickup unit is adjusted at an analog gain by an image adjuster. An output of the image adjuster is converted into a digital image data, and stored in a memory. A feature of the object is extracted from this digital image data to detect an object area in the image. When the object area is not detected, an analog-gain controller sends an analog-gain control signal to the image adjuster in a feedback manner-such that the image signal provided from the image pickup unit is adjusted at a different analog gain. Thus, the treatment of detecting the object area is repeated at different analog gains.

摘要： There is provided a photoelectric switch in which a beam reflected by an object to be detected is received in a trigonometric manner so that any failure in the distance measurement of the object can be prevented with employment of ordinary amplification circuit for received-light signals without enlarging the figure of the dynamic range of the circuit. In the switch, a circuit for comparing the ratio of the received-light signals to a predetermined operational level includes means for setting the nearest limit point for a set range of a detecting area to be farther than an intersection of the projected light beam with a line connecting centers of light-receiving lens and received-light detecting element so that the detection of the object can be made even when the dynamic range of the amplification circuit is saturated, whereby the presence of the object in the detecting area can be always discriminated even upon the dynamic range saturation of the amplification circuit.
