Abstract: There is provided a polymer composition using which a molded product having excellent balance between rigidity, wear resistance, viscoelastic properties, and heat resistance can be obtained. A polymer composition according to the disclosure includes (A) a conjugated diene rubber (where, a polymer corresponding to the following component (B) is excluded); and (B) a hydrogenated product of a polymer that satisfies the following (1) to (3), which is a polymer in which 80% or more of structural units derived from butadiene are hydrogenated: (1) being a copolymer of a conjugated diene compound containing butadiene and an aromatic vinyl compound, (2) including a polybutadiene block having a vinyl group content of 20% or less, and (3) including a block composed of a conjugated diene compound and an aromatic vinyl compound.

Abstract: In a hydraulic drive system, first and second multi-control valves are connected to first and second hydraulic pumps. A first regulator adjusts a tilting angle of the first hydraulic pump in a manner to decrease a discharge flow rate of the first hydraulic pump in accordance with an increase in a discharge pressure of the first hydraulic pump and an increase in a first power shift pressure. A second regulator adjusts a tilting angle of the second hydraulic pump in a manner to decrease a discharge flow rate of the second hydraulic pump in accordance with an increase in a discharge pressure of the second hydraulic pump and an increase in a second power shift pressure. The first power shift pressure is set by a first proportional valve, and the second power shift pressure is set by a second proportional valve.
