Abstract: PURPOSE: A device for analyzing the state of an infant using a crying sound is provided to inform a protector of the state by analyzing the frequency and pattern of the crying sound. CONSTITUTION: A voice sensor(1) senses a crying sound of an infant using a microphone. A filter(3) removes noise in an analog signal sensed by the voice sensor to filter into a significant signal. An amplifier(5) amplifies the filtered signal. A converter(7) converts the amplified analog signal into a digital signal. A memory device(15) stores desired output voice in a digital voice signal type through an operator(17) by a user. A microcomputer(9) analyzes the signal sensed by the converter(7) through frequency search and pattern recognition algorithm to discriminate a state. A controller(8) has the operator(17), the memory device(15) and the microcomputer(9). An output circuit(11) outputs the result of the state analysis of the microcomputer with more than one method. The operator(17) makes the user control the device. A temperature and humidity sensor(19) senses and outputs temperature and humidity in order to supply an appropriate environment to the infant. A filter(21) filters the sensed signal. And an amplifier(23) amplifies the filtered signal.

Abstract: PURPOSE: To provide an information recording medium and an information recorder capable of recording in a high density, accurately reproducing, and recording and reproducing any number of times. CONSTITUTION: An SiO2 having lower thermal conductivity than that of a columnar crystal 2 exists in a grain boundary phase 3 of the crystal 2 in a Co-Si oxide thin film 1. Accordingly, a heat transfer from the crystal 2 to another columnar crystal 2 is shut off. Since the phase 3 isolates the respective crystals 2 from each other, a crystal structure of the crystal is not affected by that of the adjacent crystals 2. Therefore, no phase change occurs except the crystal 2 in which an energy effective for the phase change is given directly from a laser beam. Since the other crystal 2 is not affected even if there is the crystal 2 overheated by the beam, a recording pit having a smaller mark length than a diameter of the beam can be accurately formed.
