The invention provides a noxious organism-controlling agent effective to control pests that have acquired a resistance to conventional Bt agents, and which has activity on Coleoptera pests. Also, the invention provides a microbe, Bacillus thuringiensis serovar galleriae SDS502 strain, that produces a toxic protein. This toxic protein can serve as the active ingredient in a noxious organism-controlling composition. The invention provides a protein having pesticidal activity that is produced by the Bacillus thuringiensis serovar galleriae SDS502 strain, and a protein having an addition, deletion or substitution of a plurality of amino acids and having similar pesticidal activity. The invention also provides a DNA encoding protein having pesticidal activity, a microbe transformed with the DNA, and a plant transformed with the DNA and its seed.

In order to accomplish the aforementioned and other objects, a resin muffler, according to the invention, is formed of a heat-resistantive synthetic resin having a property of visco-elastic plasticity in a predetermined temperature range. In the visco-elastic temperature range, the motion of the molecular chain segment of the material resin comes to be relaxed to exhibit noise creative pulsating energy dissipation owing to emission as heat energy. Since the resin muffler thus absorbs noise creative energy by dissipation at around the visco-elastic temperature range and transform the energy into the heat energy which may be emitted by radiation.

Improved precision is realized in positioning control. Provided is a servo control device that is applied to a numerical control equipment provided with a screw-feeding section that converts rotational movement of a motor to linear movement, a driven section that is linearly moved by the screw-feeding section, and a support member by which the screw-feeding section and the driven section are supported and that controls the motor so as to match a position of the driven section to a positioning instruction, including a support-member-reaction-force compensating section 311 that compensates for vibrations of the driven section due to a vibrational reaction force of the support member, wherein a transfer function provided in the support-member-reaction-force compensating section 311 includes a stiffness term for the driven section.
