A system for reporting status of and offering service to an image communication terminal is provided. An apparatus according to aspects of the present invention includes an absorption region including a first type of semiconductor region proximate to a second type of semiconductor region. The vibration isolator is located between the end surface of the sensor portion and the supporting surface of the casing to join the sensor portion to the casing. A controller calculates from the positions of the First Purkinje points the wearer’s gaze parallax angle andor the distance to an object of interest on which the gaze of the wearer’s eyes converges. The invention also relates to a shaped body made of a superconducting material which is based on BaCuO and which can be obtained by using the above-mentioned method. These compositions exhibit better facture toughness, especially at low temperatures.
