A composition for pickling a welded portion and a rust-generated portion according to installation of pipes, structures, plants, and so on formed of stainless steel, and for forming a passive state film thereon is provided. More particularly, the present disclosure relates to a neutral agent for passivating a surface of stainless steel metal in which a neutral agent is obtained by neutralizing a basic aqueous solution to 6.9 pH to 7.1 pH and aerated with carbon dioxide-free air to increase the amount of dissolved oxygen, so that an oxidation reduction potential in a range of 170 mV to 310 mV is obtained.

Pickling and passive film treating agent for removing scales and rusts on welding parts of stainless steel pipes and structures

A chip-on-film (COF) package includes a base film, a semiconductor chip mounted on a chip mounting region of a top surface of the base film, a plurality of top inner output conductive patterns, a plurality of bottom inner output conductive patterns and a plurality of landing vias. The top inner output conductive patterns are formed on the top surface of the base film and respectively connected to chip inner output pads formed on a bottom surface of the semiconductor chip. The bottom inner output conductive patterns are formed on a bottom surface of the base film. The landing vias are formed to vertically penetrate the base film and to respectively connect the top inner output conductive patterns and the bottom inner output conductive patterns. The landing vias are arranged within the chip mounting region to form a two-dimensional shape.

Provided are a method and apparatus for managing power of a portable information device. The apparatus includes: a display unit displaying a power management mode picture when a wake-up signal is input during a low-power consumption state of the portable information device; and a processing unit setting the portable information device again in the low-power consumption state when a user's input, as a response to the power management mode picture, is not received within a predetermined time after the power management mode picture is output to the display unit. Accordingly, even when a button on the portable information device is accidentally pressed, battery thereof can be prevented from being needlessly consumed.

The present invention provides novel microorganisms,CJJA21 (Accession No. KCCM-10222), which is resistant to sodium azide, andCJJA22 (Accession No. KCCM-10223), which is resistant to &#x3b1;-aminobutyric acid. These microorganisms are capable of producing L-glutamine in a higher yield than the known strains. The present invention further provides processes for producing L-glutamine using the microorganisms of the invention.

Microorganisms and processes for producing L-glutamine

A power supply apparatus is provided, which includes a power supply section, a switch device having at least two microswitches, and a microcontroller. The switch device further includes an assembly holder, and a printed circuit board accommodating the microswitches thereon, a pushbutton with at least two legs, and elastic member. The microcontroller controls the power supply section in accordance with the states of the microswitches. The microcontroller determines erroneous operation of a pushbutton.
