A drive steel member for driving engagement with a rotary drilling machine, including a chuck adapter having main body and chuck seating means and being constructed and arranged in fixed, sealed relation on one end of the drive steel member.

The power source contains a plurality of batteries stacked in more than three tiers within a battery case divided into a first sub holder case and second sub holder case, and the first sub holder case contains the batteries in a larger number of tiers than the second sub holder case. An intermediary duct is provided between the two sub holder cases, and a first outer duct and a second outer duct are respectively provided outside each of the two sub holder cases. The batteries in the holder case are cooled by the cooling air which flows from the intermediary duct through the holder case into the outer duct for exhaustion. Further, the second outer duct is designed to experience a larger pressure loss than the first outer duct.

To enable an air velocity of sampling air to be precisely measured, a smoke detector (S) includes: a smoke detection part (22) connected to a sampling pipe (11); a fan (12) that sucks sampling air (SA) into the sampling pipe; and an air velocity sensor (15) that measures an air velocity of the sampling air within the sampling pipe. The air velocity sensor (15) is disposed at a primary side of the fan (12), and a straightening vane (25) is disposed between the air velocity sensor (15) and a suction port (12a) of the fan (12).

A honeycomb structure, including: a pillar-shaped honeycomb structure body having a first end face and a second end face and including a porous partition wall disposed so as to surround a plurality of cells, the plurality of cells extending from the first end face to the second end face and serving as a through channel of fluid, whereinthe partition wall has a porosity of 45 to 65%,the partition wall has an average pore diameter of 15 to 25 μm, andthe partition wall has a cumulative pore volume, which is measured by mercury intrusion porosimetry, such that a pore volume ratio of pores having pore diameters of 10 μm or less relative to the overall pore volume of the partition wall is 10% or less, and a pore volume ratio of pores having pore diameters of 40 μm or more is 10% or less.

A flow path member includes an orifice section, a pressure regulating section, a filter section, and a distribution section joined together integrally, and these components are detachably provided between insulating seals. In the orifice section, orifice holes are formed around a fuel gas supply passage. In the pressure regulating section, a substantially ring shaped pressure regulating chamber is formed. In the filter section, a plurality of filter holes are formed. The orifice holes and the filter holes are connected through the pressure regulating chamber. In the distribution section, a plurality of distribution grooves for distributing the fuel gas flowing through the fuel gas supply passage in a stacking direction to flow along a separator surface, and a circular groove for supplying the fuel gas to the filter section are formed.

The invention relates to a dual-cycle reverse osmosis device and a reverse osmosis treatment method. The dual-cycle reverse osmosis device comprises a single-cycle water saving loop communicated with pipelines of an aftertreatment device and a supercharging device by a water inlet electromagnetic valve between a water inlet pipe and a thick water discharge outlet, wherein a loop is additionally arranged on the single-cycle water saving loop to form a dual-cycle water saving loop. The dual-cycle water saving loop consists of a first tee pipe, a second tee pipe, a third tee pipe, a fourth tee pipe, one-way valves, a one-way throttle valve and a pulse electromagnetic valve, wherein the first tee pipe and the second tee pipe are arranged between the water inlet electromagnetic valve and the supercharging device; the third tee pipe and the fourth tee pipe are arranged between a thick water opening of the aftertreatment device and the thick water discharge outlet and communicated with each other through a pipeline; the one-way valves limit water to only flow to a water inlet opening of the supercharging device and are respectively arranged between the first tee pipe and the fourth tee pipe as well as between the second tee pipe and the third tee pipe; the pulse electromagnetic valve is arranged between the third tee pipe and the fourth tee pipe; a throttling device is arranged between a water outlet of the pulse electromagnetic valve and the thick water discharge outlet.

A multi-cylinder hermetic compressor which comprises a first muffler chamber, a second muffler chamber, and a plurality of coolant channels which connect the first muffler chamber and the second muffler chamber. A check valve having a reed valve structure and comprising a fixed end at one end is provided at the first muffler chamber side in a first discharge port. The first discharge port is disposed so as to be shifted, relative to the fixed end, in one direction of rotation in the circumferential direction centred on a crank shaft. A coolant channel, from among the plurality of coolant channels, that is disposed in the position furthest from the first discharge port in the abovementioned direction of rotation has a smaller cross-sectional area than at least one of the other coolant channels.
