Abstract: A biological specimen observation apparatus whereby observation of a biological specimen can be performed accurately. In macro observation, a biological change region is extracted from a macro image, a micro observation point corresponding to an extracted biological change region is registered, and an object for tracking is identified. In micro observation, it is judged from the micro image whether or not biological change has continued in the biological change region at the micro observation point, and the registered micro observation point is updated on the basis of this judgment result. It is possible to carry out both macro observation for detecting a biological change region and micro observation for observing the progress of growth of a partial minute region where biological change has been exhibited, and to carry out accurate observation of a biological specimen.

Abstract: The focus control culture observation apparatus enable simple and reliable detection of a focusing position of an objective lens on a subject and with certainty. When a focusing position is detected, an area, which includes an edge portion of the culture medium drop is selected as an AF area which is to be a target of detecting the focusing position of the objective lens on the culture medium drop. The apparatus detects the focusing position on the culture medium drop based on an observation image of the AF area. By detecting the focusing position as a targeting area that is different from an area which is near the edge of the culture container and where illumination unevenness is generated, the detection accuracy can be improved.

Abstract: An aqueous solution of alkali hexahydroxo platinate is produced. As a alkali hexahydroxo platinate, sodium hexahydroxoplatinate or potassium hexahydroxoplatinate is used. The aqueous solution of alkali hexahydroxo platinate is passed through a hydrogen form cation exchange resin layer in a cation exchange resin tower. The aqueous solution of alkali hexahydroxo platinate makes contact with the hydrogen form cation exchange resin of the hydrogen form cation exchange resin layer, thus a suspension of hexahydroxo platinic is generated. If gamma rays are irradiated to the suspension, a platinum oxide colloidal solution in which colloidal particles including a platinum dioxide, a platinum monoxide, and a platinum hydroxide exist is generated. In a platinum oxide colloidal solution, the content of impurities is little and a noble metal compound is dispersed stably in water.

Abstract: An electrochemical corrosion potential sensor has a sensor unit, a lead wire and a quasi-reference electrode. A sensor unit includes a tube-shaped insulator, a tube-shaped metal casing joined to an end portion of the insulator, and a Pt electrode joined to another end portion of the insulator.

Since an electrochemical corrosion potential sensor has the quasi-reference electrode, the measurement of the corrosion potential of a structural member of a nuclear power plant and an abnormality occurrence (water intrusion) can be accurately detected during the operation of a nuclear power plant.

Abstract: An object of the present invention is to provide a high-preference game system that can reduce a game development burden of a game system operator, can increase the desire of a player to iteratively play a game, and enables a player to play a game without aversion. When a player requests a game open in a dungeon, 5 points among the points retained by the player is consumed, and 3 points are temporarily pooled in the dungeon. When the player succeeds in satisfying a clear condition of the dungeon, a total of 13 temporarily-pooled and not pooled points is added to a retention point of the player. Also, when the player fails to satisfy the clear condition of the dungeon, the temporarily pooled points are pooled in the dungeon.

Abstract: A hydrogen treatment facility for treating hydrogen without using a power source is disposed outside a reactor containment vessel and in an upper portion of a reactor building. A hydrogen detector detecting hydrogen in the reactor building is connected to a control apparatus operated by an independent power source activated at the time of a station black-out. A circulation passage for air circulation generated in the reactor building is disposed in the reactor building and outside the reactor containment vessel. A hydrogen treatment duct connects to the circulation passage and a gangway and a room with equipment. During a severe accident and station black-out and when hydrogen concentration detected by the hydrogen detection apparatus exceeds a set concentration, the hydrogen treatment duct is put in use by the control apparatus. Air containing the hydrogen is introduced into the hydrogen treatment facilities through the hydrogen treatment duct and the circulation passage.
