Abstract: From a parameter setting unit, a user enters values for monitor start time (STime), check time (ETime) and a telephone number for notification (TelNo). The entered parameter values are stored into a storage unit. A door opening/closing detection unit detects opening/closing of e.g. a bathroom door. During the period from STime to ETime, the number of detections is counted and if the counted value is at most a predetermined value, it is determined as abnormal. When the abnormality is detected, a communication unit is automatically connected via a general public line to TelNo set by the user. A telephone to be notified is then notified of the abnormal condition of an inhabitant. Thus, an abnormal condition detecting system can be provided capable of appropriately detecting the abnormal condition of the inhabitant and promptly taking action thereon.

Abstract: In a magnetic sensor having soft magnetic metallic elements disposed in opposite sides of a bridge circuit for sensing an external magnetic field by using a phenomenon where a skin depth of the soft magnetic metallic elements changes in dependence on a strength of the external magnetic field, each of the soft magnetic metallic elements is formed in a zigzag shape having parallel sections extending in a direction of the external magnetic field. The soft magnetic metallic element may have a multi-layer structure where soft magnetic layers are laminated with a non-magnetic insulator layer interposed therebetween.

Abstract: A display range control apparatus includes an external storage unit in which position data representative of two points in a horizontal direction on a screen of a raster scan monitor are stored in advance together with still picture pattern data and character data. A counter is incremented for each dot or pixel on the screen. In a range where each of the position data is coincident with a count value of the counter, a masking signal is obtained. The masking signal is used for gating picture data using a gate circuit. The picture data outputted from the gate circuit is converted into a video signal which is then applied to the monitor.

Abstract: An amplifier circuit comprising an input amplifier stage, a push-pull output stage, a bias stage having the same construction as the input amplifier stage, a first resistor to be given a current flowing through the bias stage, second and third resistors connected along with the first resistor between a power supply and the ground in series therewith, and fourth and fifth resistors connected between the output point of the push-pull output stage and the ground in series therewith. The point of connection between the fourth resistor and the fifth resistor is connected to the input amplifier stage to provide a negative feedback loop having no capacitor.
