Abstract: A wafer temperature adjusting device includes an upper surface, a wafer support mechanism that supports a wafer above the upper surface in a state where a distance between the upper surface and the wafer is maintained within a predetermined range and a first space between the upper surface and the wafer communicates with a second space above the wafer, a stage that adjusts a temperature of the upper surface, and a gas supply unit that supplies a heat transfer gas to the first space and the second space.

Abstract: A display information conversion apparatus includes a game process circuit (104) by which a game program stored in a memory (32) of a memory cartridge (30) for a first game machine is executed, the game process circuit (104) is approximately the same as that of the first game machine. Bit-serial dot data is outputted from the game process circuit (104), and converted into bit-parallel character data by a digital video data interface (114), and the character data is written in a buffer RAM (116). The character data is transferred to a second game machine coupled to a raster-scan display through a connector (113), so that a game image according to the game program stored in the memory is displayed on the raster-scan display.
