A cross-linked rubber exhibits high strength and excellent abrasion resistance as compared with a known cross-linked rubber. The cross-linked rubber is obtained by cross-linking a rubber composition that includes a hydrogenated conjugated diene-based polymer, an olefin-based rubber, and a cross-linking agent, the hydrogenated conjugated diene-based polymer being a hydrogenated product of a polymer that includes a structural unit derived from butadiene, and including at least one of an amino group and a hydrocarbyloxysilyl group at one terminal or each terminal.

Provided is a tire member which is satisfactory in low fuel consumption performance and exhibits higher strength and more excellent abrasion resistance as compared with conventional ones. The tire member is a tire member obtained by subjecting a composition containing a hydrogenated conjugated diene polymer and a crosslinking agent to a crosslinking treatment, wherein the hydrogenated conjugated diene polymer is a hydrogenated product of a conjugated diene polymer that has a structural unit derived from butadiene and has a functional group at one end or both ends and the functional group is one or more groups selected from the group consisting of an amino group, an imino group, a pyridyl group, a phosphino group, a thiol group, and a hydrocarbyloxysilyl group.

In a control device, a pilot-operated first check valve connects a solenoid-operated first directional control valve to a lock side chamber of a lock cylinder installed in a quick coupler. A pilot-operated second check valve is connected to the lock cylinder unlock side chamber, a solenoid-operated second directional control valve connected between the second check valve and the first directional control valve. The first and second directional control valves are controlled by a controller with processed signals input from a mode selector switch, first sensor detecting a buck closing pilot pressure, and second sensor detecting a bucket closing working pressure.

A modified conjugated diene-based polymer is produced that is a modified product of a conjugated diene-based polymer obtained by polymerizing a conjugated diene compound, or polymerizing a conjugated diene compound and an aromatic vinyl compound, in the presence of an alkali metal compound or an alkaline-earth metal compound. The modified conjugated diene-based polymer is produced by a production method that includes a main chain modification step that reacts at least either an unsaturated bond or a functional group that is included in a terminal-modified polymer and is not situated at a terminal of the terminal-modified polymer, with a specific compound that includes a functional group that interacts with silica, the terminal-modified polymer being obtained by introducing a functional group that interacts with silica into at least one terminal of the conjugated diene-based polymer.

Provided is a polymer composition for use in the production of a crosslinked polymer having excellent tensile strength and abrasion resistance. A polymer composition comprising a polymer having multiple anionic functional groups and a polymer having multiple nitrogenated functional groups each represented by formula (1). The anionic functional groups are at least one group selected from a carboxy group, a sulfo group and a phosphate group. In one embodiment, each of the nitrogenated functional groups represented by formula (1) is bound to a structure derived from a conjugated diene compound or a structure derived from an aromatic vinyl compound.

A valve element has a packing material, whose one side surface touches and leaves a valve seat as a sealing surface, and a support member, which is driven in opening and closing directions of a valve section by actuating an actuator. The support member includes a supporting surface, which is in contact with a side surface of the packing material opposite to the sealing surface of the packing material, and an engagement part, which supports a peripheral edge part of the packing material in a manner such that the engagement part is engaged with the peripheral edge part. A ring-shaped fluid flow passage is formed between the supporting surface of the support member and the packing material, and this fluid flow passage communicates with an upstream passage.

Control valve

A piston is configured by a piston body and a support such that the piston is divided, along a direction of axis line, into the piston body, which is formed integrally with a valve element, and the support, which is provided separately from the valve element. A piston ring, which slides along a body, is held between the piston body and the support. The piston body is constantly in contact with one side face of the piston ring, and the support is constantly in contact with the other side face of the piston ring.

Electromagnetic valve

A pilot valve element includes a metallic pilot valve body formed integrally with a plunger, a flexible sealing member, fitted on a tip of the pilot valve body, which touches and leaves a pilot valve seat, and a stopper for restricting the displacement of the pilot valve element relative to a driven member in a manner such that the sealing member is stopped in a direction of axis line after the sealing member has seated on a pilot valve seat. The stopper is configured such that the pressure-receiving diameter of the sealing member, which receives a pressure difference between an upstream side and a downstream side of the pilot valve, remains unchanged from when the sealing member comes in contact with the pilot valve seat until when the sealing member is stopped by the stopper with the result that the sealing member has completely seated on the pilot valve seat.

In a multi-deck-elevator-equipped building control system, operating modes of an elevator control portion include a double operating mode. In the double operating mode, only a first cage is permitted to stop at first cage stop floors, and only a second cage is permitted to stop at second cage stop floors that are distinct from the first cage stop floors. A building fixture control portion has a first group control portion for associatively controlling an electrical fixture on the first cage stop floors and a second group control portion for associatively controlling an electrical fixture on the second cage stop floors.

An elevator apparatus has first and second car suspending pulley devices mounted on a car. First and second counterweight suspending pulley devices are mounted on a counterweight. In the upper portion of the interior of a hoistway, there are arranged a car side return pulley device and a counterweight side return pulley device. A main rope suspending the car and the counterweight has first and second ends. The portion of the main rope extending from the first car suspending pulley device to the first end and the portion of the main rope extending from the second car suspending pulley device to a driving sheave are respectively arranged on opposite sides of a vertical plane passing centrally through the car.

After a reducing gas is mixed with an inert gas by a mixer, a resultant mixed gas is heated by a heater and made to a hot mixed gas which is dehumidified and dried and the temperature of which is increased. The mixed gas is injected to a subject from an injection port formed in a soldering iron, and thereby soldering is performed by heating and melting solder with the soldering iron in the atmosphere of the mixed gas.

Gas injection type soldering method and apparatus

An elevator system has a pair of horizontally opposed vertical surfaces defining therebetween a doorway or opening to an elevator cage and a door moving horizontally to open and close the opening. In particular, the system has a first optical device having a light emitter for emitting light and a second optical device having a light receiver for receiving the light emitted from the light emitter. The first and second optical devices are positioned in a vertical plane crossing the opening and adjacent to the opening. One of the first and second optical devices is positioned below the other of the first and second optical devices and mounted in the vertical surface.
