Abstract: Temperature uniformity of a reaction liquid in a plurality of reaction containers of an automatic analysis device is maintained by a heat block. A strip-shaped heater heats the heat block, and is wound and attached on an outer circumference of the heat block so that both end regions of the strip-shaped heater are adjacent to each other. The strip-shaped heater includes a heat generating resistor that is heated by applying an electric current, an insulating film sandwiching the heat generating resistor, and first and second electrical feed lines that are attached to both end portions of the heat generating resistor and supply power to the heat generating resistor. The width of the heat generating resistor in both end regions of the strip-shaped heater is formed to be narrower than the width of the heat generating resistor in the other region thereof.

Abstract: Provided is an automatic analyzer having a rapid start-up of a heat block while precisely controlling a temperature of a reaction solution. In the automatic analyzer equipped with a reaction-vessel-holding part, a heat block having a heat source to heat the reaction vessel, and a cooling system having a low temperature region and a high temperature region, an outer peripheral part of or below the reaction-vessel-holding part is defined as a heat transfer space, there are provided a heat transfer passage connecting the heat transfer space and the high temperature region, a heat medium circulating through the high temperature region, the heat transfer passage, and the heat transfer space, and a flow rate control means configured to control a flow rate of the heat medium in the heat transfer passage, and a temperature detection means is provided on a downstream side of the high temperature region.

Abstract: A solid-liquid separation device performs dehydration/deoiling from a mixture of water and/or oil and a solid. Substance A is capable of dissolving water and oil. The device includes substance B circulated while generating phase change in a closed system; a compressor; a first heat exchanger exchanging condensation heat of substance B and evaporation heat of substance A; a second heat exchanger exchanging evaporation heat of substance B and condensation heat of substance A; and a treatment tank for mixing substance A with an object to be treated; substance A having been evaporated while separated from the water or the oil in the first heat exchanger, and condensed in the second heat exchanger. The first heat exchanger is lower than the treatment tank in a vertical direction, and a connection port of the first heat exchanger and a lower portion of the treatment tank are connected with a flow path.

Abstract: To provide a solid-liquid separation system in which a stable operation can be continuously conducted and the introduction cost and the running cost can be suppressed, in cases where moisture or oil are separated from a substance containing moisture or oil by using changes in phase of a working fluid having a nature of dissolving moisture or oil in a liquid phase.
