Abstract: A shovel includes a lower traveling body; an upper swinging body swingably mounted on the lower traveling body; an operator's cab mounted on the upper swinging body; a display device provided in the operator's cab; and a processor configured to cause the display device to display information about custom setting before a start of operation of the shovel.

Abstract: A shovel according to an embodiment of the present disclosure includes an operation mode setting unit that selectively sets an operation mode to be used from among a plurality of operation modes having different output characteristics related to an operation of the shovel in response to an input from a user to an operation mode changeover switch, a mode level setting unit that selectively sets a level to be used in the operation mode from among a plurality of levels of output related to an operation of the shovel defined for each of the plurality of operation modes in response to the input from the user to a mode level adjustment dial, and a storage unit that stores the level set in the operation mode before switching in association with the operation mode before switching when the operation mode is switched by the operation mode setting unit.

Abstract: A technique that can suitably restrict a rotation rate of a motor of an excavator is provided. An excavator according to an embodiment of the present disclosure includes an engine, an engine rotation rate adjusting dial that receives an input regarding changing of the rotation rate of the engine, and an engine control part that restricts the rotation rate of the engine. When the rotation rate of the engine is restricted to lower than or equal to a predetermined upper limit by the engine control part, the rotation rate of the engine is maintained to lower than or equal to the predetermined upper limit even when the engine rotation rate adjusting dial receives an input that makes the rotation rate of the engine higher than the predetermined upper limit.

Abstract: A dynamic wireless power transfer system performs, through a plurality of primary coils installed along a traveling direction of a road and a secondary coil mounted in a vehicle, power transfer to the vehicle while the vehicle is traveling. The secondary coil is an M-phase coil including M coils, M denoting an integer which is two or higher. The M coils each include a coil end extending along a front-rear direction of the vehicle and a main coil portion extending along a width direction of the vehicle, the M coils each being configured such that a magnetic resistance of a magnetic path where a magnetic flux of the coil end passes is higher than a magnetic resistance of a magnetic path where a magnetic flux of the main coil portion passes.

Abstract: A contactless power supply system is provided for supplying electric power to a vehicle in a contactless manner during traveling of the vehicle. The contactless power supply system includes a plurality of primary coils installed along a traveling direction in a road and a secondary coil mounted to the vehicle. Each of the primary coils is a single-phase coil with the secondary coil being a multi-phase coil, or is a multi-phase coil with the secondary coil being a single-phase coil.

Abstract: An aqueous solution formulation containing Compound (I) can be manufactured by performing a first step of preparing a dissolution liquid obtained by dissolving a compound represented by Formula (I) below or a pharmacologically acceptable salt thereof and a compound represented by any of General Formulas (II) to (IV) below in an organic solvent, a second step of removing the organic solvent from the dissolution liquid, and a third step of adding a solution to residual substances obtained through the second step to dissolve the residual substances.

Abstract: A friction drive belt (B) includes short fibers (14) and carbon black (18) both scattered so as to be exposed at a surface of at least a contact part (13) of a rubber belt body (10) with a pulley. The short fibers (14) include short, high modulus fibers made of polymers having a main chain which does not contain an aromatic compound and having an initial tensile resistance, measured according to JIS L 1013, of equal to or greater than 100 cN/dtex, and the carbon black (18) contain large-particle-diameter carbon black having an iodine absorption, measured according to JIS K 6217-1, of equal to or less than 40 g/Kg, and/or a specific surface area, measured by nitrogen adsorption according to JIS K 6217-2, of equal to or less than 40 m2/g.
