Abstract: In a crawler type work machine, when switching from a pivot turning mode to a straight travel mode or a slow turning mode, a controller is configured to maintain a rotation speed of the turning motor until after a first timing at which the inside steering clutch begins partial engagement.

Abstract: Provided are an additive for positive electrodes, which is capable of increasing the output of a lithium secondary battery and is capable of maintaining cycle characteristics even during high-speed charge and discharge; and a positive electrode for lithium secondary batteries. The additive for positive electrodes of lithium secondary batteries, which contains, as an essential constituent, a substituted polythiophene that has a repeating unit, which is obtained by substituting a hydrogen atom in the 3-position and/or in the 4-position of a thiophene ring with at least one group that is selected from the group consisting of a perfloroalkylalkoxy group, a perfloroalkoxy group, a perfloroalkoxyalkyl group and an alkyl group substituted with the perfloroalkylalkoxy group, as at least a part of a thiophene repeating group.

Abstract: The photosensitive composition of the present invention includes: (1) a radical initiator (A); (2) an acid generator (B) and/or a base generator (C); and (3) a polymerizable substance (D), wherein at least one of the radical initiator (A), the acid generator (B) and the base generator (C) are to generate an active species (H) on exposure to active rays, the active species (H) reacting with the radical initiator (A), the acid generator (B) or the base generator (C) to generate another active species (I), the active species (I) initiating polymerization of the polymerizable substance (D), the active species (H) or (I) is an acid or a base, and the photosensitive composition contains substantially no colorants, metal oxide powder, or metallic powder.

Abstract: Provided is an electroconductive coating composition which is soluble in solvent and exhibits excellent proccessability, and the electric conductivity of which rarely lowers even under high temperature conditions. An electroconductive coating composition (A) characterized by containing both a substituted polythiophene (P) and a dopant (D), said substituted polythiophene (P) being a polythiophene in which at least some of the thiophene repeating unit are each a thiophene repeating unit (?) which is substituted at the 3-position and/or the 4-position of a thiophene ring by (a) a polyether group that comprises 1 to 9 C2-4 oxyalkylene group repeating units and that has a C1-15 alkoxy group at one terminal, (b) an alkoxy group, (c) an alkoxyalkyl group, or (d) an alkyl group that is substituted or unsubstituted by the polyether group (a).
