Abstract: A procedure simulator that includes an animal heart to which a first balloon is inserted into a left ventricle of the heart and to which a second balloon is inserted into a right ventricle of the heart. A pump system makes the first balloon and the second balloon expand and contract via an operating fluid (L). A blood supply unit then directly supplies blood to three coronary arteries of the heart while the balloons are expanding and/or contracting.

Abstract: A non-volatile semiconductor memory device raises the word line voltage by use of the edge of a clock to read out memory cell data. A plurality of voltage raising circuits are connected in parallel and each of the voltage raising circuits raises a power supply voltage. A level shifter is connected to the outputs of the plurality of voltage raising circuits to drive the word line. Driving means drives each of the plurality of voltage raising circuits by use of clocks each having only one edge in a period from the address changing time to the memory cell data readout starting time at which the precharging operation is terminated. The clocks for driving the voltage raising circuits have a phase difference with respect to one another for the respective voltage raising circuits.

Abstract: An image reproducing device includes a container for storing a strip-like photosensitive material in a condition that the photosensitive material is rolled, the photosensitive material having a mark at a predetermined length from a final end thereof. Rollers pull out the rolled photosensitive material from the container and convey the photosensitive material. A cutter cuts the conveyed photosensitive material into a sheet-like photosensitive sheets one by one. A pair of developing rollers roll the cut photosensitive sheet put together with a transfer sheet between which a developer-containing pod is interposed. A detector detects the marking of the conveyed photosensitive material, and a controller inhibits the cutter from cutting the photosensitive material in a case where the detector detects the mark of the conveyed photosensitive material.
