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 object detecting device utilizes a pyroelectric sensor providing a sensing current, a voltage amplifier providing an amplified voltage proportional to the sensing current, and a level monitor providing a detection signal when the amplified voltage exceeds a detection threshold. The device has a standby mode where the voltage amplifier receives a limited source current to provide the voltage of low amplification, and the level monitor provides a wake-up signal when the low amplified voltage exceeds a preliminary threshold lower than the detection threshold. In response to the wake-up signal, the device is switched to an operation mode where the amplifier receives a rated source current to provide a voltage of high amplification for comparison with the detection threshold. Thus, the amplifier is kept to be less-power consuming in the absence of the wake-up signal, reducing a power requirement.

摘要： Disclosed is a distance measuring apparatus for measuring a distance to a target object also its shape precisely without influence of noise, which is applied to a invader monitoring system. This apparatus comprises a clock signal generator unit, a modulated light projector unit, a light receiver unit, and a demodulator unit, and obtains a range image presenting signal levels changing according to the distances to the objects including the target object by irradiating light onto the objects and receiving reflected light. In the demodulator unit, the range image is processed for evaluating and removing noise components, for interpolating and averaging noise removed region, and for selecting the target object region. Those processes are carried out from the following point of view, the variation of the distance signal levels, the received quantity of light, and the variation of the received quantity of light. Thus a range image without no noise and including substantially only the target object data is obtained, and therefore it is possible to measure a distance to the target object and its shape precisely without influence of noise.
