This invention has a series of multiple parallel plates that form desalination chambers between them that have seawater or other saline water flowing down the inside of one plate of each chamber. Steam which is generated by solar heat or other heat source condenses on the outside of first chamber of the series on the plate, which has seawater running down it. This releases heat that evaporates the seawater. The vapor flows to the other wall (plate) of the desalination chamber and condenses, and this releases heat that flows through the plate to the next stage of parallel plates and evaporates seawater flowing down the other side of the plate. Each succeeding stage operates at a lower temperature than the previous stage. The final stage is cooled by the evaporation of seawater into the air. One embodiment of the invention has the parallel plates sloped at an angle to the horizontal so that the seawater flows down on the lower plate and evaporates with heat supplied from below. The vapor condenses on the ceiling of the chamber. Since each succeeding stage upward is at a lower temperature, the vapor pressure will be lower in succeeding stages. This pressure differential can be used to pump the seawater from one stage to the next higher stage.

A resist removing device 1 functions to remove a resist from a substrate while preventing occurrence of popping phenomenon and at the same time attains reduction in cost of energy for the resist removing and has a simplified constitution. The resist removing device 1 is equipped with a chamber 2 for containing therein a substrate 16 (for example, a substrate having a high-doze ion implanted resist), and with a pressure below the atmospheric pressure, the chamber 2 is fed with ozone gas, unsaturated hydrocarbons and water vapor. The ozone gas may be an ultra-high concentrated ozone gas that is produced by subjecting an ozone containing gas to a liquefaction-separation with the aid of a vapor pressure difference and then vaporizing the liquefied ozone. For cleaning the substrate 16 thus treated, it is preferable to use ultra-pure water. The chamber 2 is equipped with a susceptor 15 for holding the substrate 16. The susceptor 15 is heated to a temperature of 100° C. or below. An example of the means of heating the susceptor is a light source that emits infra-red rays.

Provided is a forming method comprising fixing an object in a mold of a forming apparatus comprising a water pressure or vapor pressure generator and the mold communicated with the water pressure or vapor pressure generator; generating water pressure or vapor pressure using the water pressure or vapor pressure generator and then injecting the water pressure or vapor pressure into the mold; and forming the object fixed in the mold using pressure generated by the water pressure or vapor pressure, and a forming apparatus used in the same. According to the present invention, it is possible to form an under-cut portion and other fine shapes which could not be formed by a conventional forming method and also it is possible to solve the problems such as the thickness variation and the whitening phenomenon after the forming process.

The invention belongs to the field of energy storage materials adopting mixed molten salt and particularly relates to a mixed molten salt type heat transfer and storage working medium and an application thereof. The mixed molten salt type heat transfer and storage working medium is characterized by comprising components in percentage by mass as follows: 20wt%-30wt% of Ca(NO3)2*4H2O, 41wt%-50wt% of KNO3,5wt%-20wt% of NaNO3 and 10wt%-31wt% of NaNO2. The application of the mixed molten salt type heat transfer and storage working medium is characterized in that the mixed molten salt type heat transfer and storage working medium is widely applied to the medium-high-temperature heat transfer and heat storage fields, such as solar thermal power generation and storage, wind power curtailment, photoelectricity curtailment and ''coal to electricity'' heat storage and supply or industrial waste heat recovery and storage. The cost of ingredients used for preparing the mixed molten salt is low, and the preparation process is very simple; the thermophysical property of the mixed molten salt is very stable, the separation phenomenon of certain ingredients cannot be caused in the use process, the molten salt has a good heat transfer performance in a liquid-state temperature zone, and the saturated vapor pressure is lower than double barometric pressure. The working medium has low corrosivity for metal and has a wide application range.
