Abstract: A dehumidifying apparatus with dual dehumidifying rotor includes an air supply fan for introducing outside air; a first cooler for cooling the air being introduced through the air supply fan; a first dehumidifying rotor where a dehumidifying area and a regeneration area are formed in a circumferential direction; a second dehumidifying rotor where a dehumidifying area, a purge area and a regeneration area are formed in a circumferential direction; a heater disposed between the second dehumidifying rotor and a dry room that heats air passing each dehumidifying area of the first dehumidifying rotor and the second dehumidifying rotor and being supplied to the dry room; a first regeneration heater that heats air passing the purge area of the second dehumidifying rotor and being returned to the regeneration area; and an exhaust fan that discharges air that passed each regeneration area of the first and second dehumidifying rotors to outside.

Abstract: The present disclosure relates to a multi-stage dehumidification system for local area dehumidification of dry room, the system including a main dehumidification part formed to have an inside space that is sealed from outside; a main dehumidifying device for controlling that the relative humidity of the inside of the main dehumidification part is smaller than the relative humidity of the outside of the main dehumidification part; at least one local area dehumidification part that is partitioned within the main dehumidification part, and that has an inside space that is sealed from the main dehumidification part; and a local area dehumidifying device for controlling that the relative humidity of the inside of the local area dehumidification part is smaller than the relative humidity of the inside of the main dehumidification part, wherein the local area dehumidification part includes an opening for entry and exit of objects; a moisture penetration prevention part that protrudes to outside from an edge of the o

Abstract: A hybrid operating apparatus including an absolute humidity sensing unit configured to sense an absolute humidity of air supplied to a dehumidifying rotor; a dew point temperature sensing unit configured to sense a dew point temperature of air returned from a dry room; a regeneration exhaust temperature sensing unit configured to sense a temperature of exhaust air regenerated in the dehumidifying rotor; a control unit configured to operate the regenerative heater to a regeneration temperature corresponding to the sensed absolute humidity; and a memory unit configured to store the regeneration temperature of the regenerative heater.

Abstract: The present invention relates to a tension locking member for an earring, more particularly, a tension locking member for an earring useful for removably attaching the earring to an earlobe, comprising a plate spring having an embossed projection at one side, wherein the plate spring is constructed and assembled to allow the embossed projection to be hooked and supported by two fixing pieces in a movable manner when the fixing pieces formed on both ends of the tension locking member are bent and supported in a fixed position so that it can protect the plate spring from being detached or released and, at the same time, to inhibit or reduce local stress load on the plate spring generated by repeatedly using the tension locking member to essentially prevent partial cutting of the plate spring, and obtain a tension effect for the tension locking member even by slight force, thereby, accomplishing smooth and enhanced wearing sense.
