A wireless relay device for relaying packets via a wireless network includes an aggregator and a transfer controller. The aggregator is configured to aggregate a plurality of sets of data respectively included in a plurality of first packets transmitted from a plurality of wireless devices in the wireless network and under the wireless relay device to generate a second packet. The plurality of first packets is addressed to the wireless relay device. The transfer controller is configured to transfer the second packet to a transfer destination.

Wireless relay device, processing apparatus, wireless communication system, and wireless communication method

A wireless device that performs an operation based on setting information includes a wireless communicator configured to perform wireless communication over a wireless network, a near field communicator comprising a memory storing the setting information and configured to perform transmission and reception of the setting information stored in the memory by near field communication, and a controller configured to control at least the wireless communicator.

Wireless device, gateway apparatus, and wireless communication system

A device adapter which is connectable to the field devices, includes an interface which is connectable to the field devices, a power source configured to supply electric power to the field devices connected to the interface, and a start controller configured to perform a start control of the field devices connected to the interface to make a total power consumption of the field devices connected to the interface be within a range permitted in accordance with an explosion-proof standard.

An intake air heating system for an internal combustion engine having an air cleaner of the temperature regulating type has a heating chamber to heat intake air sufficiently. The heating chamber is formed by bulging partially a heat insulating plate around an exhaust manifold of the engine. A heated-air induction pipe extends from the interior of the heating chamber to the air cleaner.

Intake air heating system for an internal combustion engine

A catalytic converter for treating engine exhaust gas includes a carrier and a casing housing the carrier. The carrier has opposite first and second ends and is formed therethrough with a plurality of passageways extending from the first to the second end of the carrier. The passageways have opposite first and second ends respectively. The first ends of the passageways are at the first end of the carrier. The second ends of the passageways are at the second end of the carrier. The casing and the second end of the carrier define a space, inside the casing, through which the second ends of the passageways communicate in common. An inlet tube is connected to the casing in such a manner as to directly communicate with a part of the first ends of the passageways, in order to supply the engine exhaust gas thereto. An outlet tube is connected to the casing in such a manner as to directly communicate with another part of the first ends of the passageways. First catalyst is carried on a part of the carrier including the passageways which directly communicate with the inlet tube. Second catalyst is carried on another part of the carrier including the passageways which directly communicate with the outlet tube. The engine exhaust gas flows past the inlet tube, a part of the passageways relating to the first catalyst, the space inside the casing, another part of the passageways relating to the second catalyst, and the outlet tube, in that order.

A catalytic converter comprises a monolithic catalyst within a casing, a gas seal member disposed around a part of the catalyst outer surface, a wire netting disposed around the remaining part of the catalyst outer surface and interposed between the casing inner surface and the catalyst outer surface, a protector member interposed between the casing inner surface and the gas seal member outer surface, the protector member being securely connected to the wire netting, thereby preventing the gas seal member from being damaged due to contact thereof with the converter casing during assembly of the catalytic converter.

Catalytic converter

A dipstick is formed of a single length of wire and comprises a generally straight main body and a loop-shaped handle portion. The wire is circular in cross section, relatively small in diameter and possesses a relatively high resilience such that the main body can resiliently flex in all directions to follow a complexly curved dipstick guiding conduit. The main body has a pair of axially spaced and radially projected stopper portions. The handle portion extends from the main body and terminates in an end which is wound round the main body between the stopper portions such that the end of the handle portion is prevented from relative movement in the axial direction of the main body.
