A surface emitting light source and projection display device using the same are disclosed, by which a highly integrated andor high-output surface emitting light source are provided in a manner that improves the structure of semiconductor light emitting units. Soluble contaminants released from the sediment are sorbed onto the surface of a sorbent material disposed within a plurality of semipermeable membrane bags disposed within the chamber. This control loop technique is applicable to any means of drain power control circuits such as: supply regulators, DC-DC converters and others. The temperature controller is configured to control a pre-heater heating temperature of the pre-heater and a print heater heating temperature of the print heater such that a surface temperature of the printing surface of the medium at the printing position becomes within a range of from 30\xb0 C. Identified errors are counted for each for distinct setting of the control registers to determine a preferred setting to best tune operation of the transceiver pair. In this way, when a strategy is selected by a player and the alterable area corresponding thereto is altered, the final hand for the game is revealed.
