Filed: 1999-05-07
Abstract: PURPOSE: A water direct-contact type air conditioner is provided to reduce costs for installation and operation by performing cooling, heating, dehumidification, humidification and air purification employing an apparatus. CONSTITUTION: Cool or hot water temporarily stored in a reservoir(21) of a water tank(20) is sprayed via a spray nozzle(40) in a duct(6) by a pump(13). For cooling and dehumidification, cool water is sprayed. Air loses its heat by a heat transfer and a mass transfer between hot air and cooled sprayed water particles while the cooling water obtains heat. Herein, the relative humidity of the air increases, whereas the humidity ratio of the air decreases. If hot water is sprayed, the temperature of the air increases while the water loses its heat. Herein, the humidity ratio of the air increases and a humidification effect is obtained. Furthermore, the air is purified by the removal of fine particles and pollutant gas in the air.

Abstract: PURPOSE: A method for detecting a non-recording area of an optical recorder/player is provided to exactly detect a header area even though a servo is unstable. CONSTITUTION: A read channel 2 signal is generated with an optical reflecting signal from an optical disk. First/second header detecting signals are generated by slicing the read channel 2 signal with a predetermined slice level. The first/second header detecting signals are AND-operated after delaying. An on time of a header mask signal is decided by counting a PLL(Phase-Locked-Loop)-wobble signal. The PLL-wobble signal is generated by hanging a PLL to a wobbled signal. An off time of the header mask signal is decided with the AND-operated signal as a reference signal. Thereby, a header area is exactly detected even though a servo is unstable.
