A holographic ROM system of the present invention includes a holographic disk for storing information in a form of hologram; a pick-up module for optically reading the information stored in the holographic disk and producing an electrical signal in response to what has been read; and a control unit. The pick-up module has at least two light sources which are controlled by the control unit and a temperature measuring device for measuring an operating temperature of said at least two light sources, and the temperature measuring device transmits a temperature signal indicating the operating temperature to the control unit.

In a holographic recording apparatus having a hologram medium for storing an interference pattern between a reference beam and a modulated signal beam, a double-layered mask for modulating a signal beam with data to generate the modulated signal beam has a first and a second opaque film and a transparent plate inserted therebetween. The first and the second opaque film face each other and have a plurality of first and second recording tracks, respectively. The first and the second recording tracks are alternately arranged, wherein the data to modulate the signal beam therewith are alternately embedded along the first and the second recording tracks such that one of two neighboring recording tracks is one of the first recording tracks and the other is one of the second recording tracks.

Disclosed herein is an installation structure of a suction hose for an upright type vacuum cleaner. The installation structure comprises a mounting part provided at either end of the suction hose and formed of a corrugated pipe having a thread shape, a pipe-shaped connecting member secured at one end to one side of the mounting part, an adapter having a securing protrusion formed on an outer surface thereof, and to which the connecting member is latched and secured so as to be restricted in axial movement while being permitted to rotate in a circumferential direction, and a receipt part to which the adapter having the securing protrusion formed thereon is inserted and secured. With this structure, the suction hose has a 360-degree rotation structure so that it is prevented from being twisted during a cleaning operation, thereby ensuring convenient cleaning while providing an appealing appearance.

A wet type air cleaner includes a purification unit installed in a housing. The purification unit includes a blower unit for directing air to cleaning water in the bottom of the housing; an inner guide for drawing up the cleaning water in the bottom of the housing; a nozzle portion for dispersing radially the cleaning water drawn up by the inner guide, the air directed by the blower unit flowing through the dispersed cleaning water; and an outer guide for guiding the directed air and the dispersed cleaning water into the cleaning water in the bottom of the housing. The blower unit, the inner guide and the outer guide are together rotated by a driving unit. The inner guide has a central portion and a spiral guide portion disposed on an outer surface of the central portion.

A wet type air cleaner includes a water tank for storing cleaning water which is installed at a bottom of a housing. The water tank has a partition plate with a central hole dividing the inner side thereof into an upper portion and a lower portion, which communicate with each other through the central hole. The air cleaner further includes a blower unit for dispersing the cleaning water and allowing air to be introduced through the air suction port into the housing and to pass through the dispersed cleaning water and a pumping unit for supplying the cleaning water stored in the lower portion of the water tank to the blower unit to be dispersed thereby.
