Abstract: A filter module mounted on an air purifier to filter air includes a first filter unit and a second filter unit detachably connected to the first filter unit and arranged to surround the first filter unit. The first filter unit includes a shape-corresponding portion having at least a portion which is formed in a curved shape having a predetermined curvature. At least a portion of the edge of the second filter unit is formed in a shape corresponding to the shape-corresponding portion, and when the filter module is mounted on the air purifier, the amount of air passing through the first filter unit per unit area is greater than the amount of air passing through the second filter unit per unit area.

Abstract: Disclosed herein are a microorganism with excellent deacetoxycephalosporin C (DAOC) productivity and a use thereof. A mutant microorganism with improved DAOC productivity and a use thereof for producing 7-aminodeacetoxycephalosporanic acid (7-ADCA) are provided.

Abstract: A monitor is disclosed, in which R/G/B signals provided from a video source are compensated to adapt to the color reproduction of the monitor, thereby obtaining the best picture quality. The monitor includes a video source for outputting one video signal, a color compensator for detecting characteristics of the video signal output from the video source and for comparing the detected characteristics with display characteristics of the monitor to compensate the color of the video signal, a video processor for processing the video signal output from the color compensator, and a display for displaying the video signal output from the video processor.

Abstract: An infrared ray clinical thermometer is disclosed. The infrared ray clinical thermometer for detecting infrared rays from an eardrum to measure a body temperature includes the following elements. A main body is provided for being held by hand. A probe part is detachably attached to the main body and has a leading end part for being inserted into an external auditory conduit, the leading end part having an inlet hole for receiving incident infrared rays. An infrared ray sensor is installed within the leading end part of the probe part. The probe part includes the following elements. That is, a hollow speculum is for being inserted into the external auditory conduit. A sensor housing is for accommodating the infrared ray sensor and is adhesively installed within the speculum. An airtight member is provided on a leading end of the sensor housing. The infrared ray sensor is made to approach the eardrum as close as possible, so that the infrared rays from the eardrum can be directly detected.
