摘要： PURPOSE:To obtain the quantitative distribution of a living body function such as metabolic circulation as an image by irradiating a subject with visible - infrared light and measuring the shape of the subject from its transmitted light data. CONSTITUTION:The shape of the sample is measured by a measurement part 2 by using a visible - infrared light source part 1 and the obtained configuration information is processed into the image by a data processing part 5 and an image display part 7 to measure the spatial distribution of the density or chemical state of the materials in the living body. In this process, the configuration state is utilized to measure the light propagation time from a light input part to a photodetection part as to different combinations of plural light input parts and photodetection parts 3, and the relative position relation between light input parts and photodetection parts is measured to measure the shape of the object body, thereby finding accurate function distribution image efficiently. Consequently, the influence of scattered light in an optical CT device is removed effectively to take an accurate medical diagnosis.

摘要： PURPOSE:To form a high integration, high speed nonvolatile random access memory device by continuously forming specific superconducting material and ferrodielectric material. CONSTITUTION:As a ferrodielectric material 5, a material having a ceramic perovskite structure exhibiting hysteresis characteristic of self-generating polarization is employed. As a superconducting material 2, a material having a ceramic perovskite structure exhibiting superconducting characteristic at a relatively high temperature is employed. In order to manufacture a memory array of these materials, an insulating film 3 is formed on a semiconductor substrate 4, a superconductor material 2 is formed on the film 2, and wirings are then formed. Thereafter, the materials 5 and 1 are continuously deposited in the same manufacturing apparatus. The material 1 may be the same or different material as or from the material 2. The material 1 is wired, and the material 5 is then etched. Thus, since both the ferrodielectric and superconductor materials can be provided in a semiconductor device, a large capacity (large scale integration).high speed semiconductor device can be formed.
