    摘要： The purpose of the present invention is to provide a new data utilization system in which, while an individual independently uses and utilizes one's own personal data, security and anonymity of the data can be effected. An information processing device used by an individual comprises: a function of transmitting, over a network, data relating to an address on a blockchain network used by the individual to a provider-side information processing device comprising a storage device that is a provision source of data associated with information about the individual; a function of referring to access data (ACT) that includes the data relating to the blockchain network address and data for identifying the provision source of the data and that is issued by the provision-side information processing device for the blockchain network address; and a function of, on the basis of the access data (ACT), acquiring the data associated with the information about the individual from the provider-side storage device and storing said data at least in a storage device or a memory of said individual.

    摘要： The pattern inspection apparatus includes: an irradiator irradiating a sample with an electron beam; an electron detector detecting an amount of electrons generated on the sample having a pattern formed thereon, by the irradiation of the electron beam; an image processor generating a SEM image of the pattern on the basis of the electron amount; and a controller acquiring defect position information on the pattern formed on the sample from an optical defect inspection device. The controller specifies a defect candidate pattern from the SEM image on the basis of the defect position information and judges whether a defect in the defect candidate pattern is to be transferred onto a wafer. The controller determines a view field of the SEM image on the basis of the defect position information and specifies the defect candidate pattern from image information on patterns displayed in the view field.

    摘要： An endoscope includes a head assembly having a first central axis for entry in a body cavity. In combination with the endoscope, a guide assembly includes a shaft sleeve having a lumen, for mounting on the head assembly therewith. An endless track device is supported around the shaft sleeve, for endlessly moving along the first central axis, for propulsion of the head assembly inside the body cavity. A support sleeve is disposed between the shaft sleeve and the endless track device, having a second central axis different from the first central axis, for supporting the endless track device movably. Preferably, the endoscope includes an imaging window area formed in a distal surface of the head assembly and offset from the first central axis. A position shift between the first and second central axes is predetermined according to a position shift between the imaging window area and the first central axis.
