A radiant tube formed of a heat resistant metal includes at least one bent tube (3A (3C)) which connects straight tubes (2A, 2B (2C, 2D)) to each other. Combustion gas from a burner 5 is fed through one of the straight tubes (2A, 2B (2C, 2D)). The radiant tube is characterized in that at least as the bent tube 3A (3C) located closest to the burner 5, there is employed a cast body having an outer diameter ranging from 150 to 210 mm and a wall thickness ranging from 3 to 8 mm.

A circuit board connector is provided. The circuit board connector includes: a connector housing which is mounted on a circuit board; and a terminal which is press-fitted into the terminal press-fitting hole of the connector housing. The terminal includes: a terminal connecting portion which is disposed through the rear side of the connector housing to be connected to a mating connector; a press-fitting portion to be fixed to the connector housing; a board fixing portion fixed to the circuit board by soldering; and a coupling portion extending and bent toward a side of the circuit board to couple the press-fitting portion with the board fixing portion. The circuit board connector also includes a stress absorbing portion provided with a center hole which is provided on a midway of the coupling portion so as to absorb a stress by being deformed.

A slot 21 is formed on each of both side walls of a connector housing 1. A housing attachment portion 12 of each fixing metal member 10 is inserted into and locked in an associated one of the slots 21. The housing attachment portion 12 is divided by a slit 14 formed in a central part thereof into both side arms 13, each of which has a hook 13a provided at the top thereof. Each of the arms 13 is inwardly bent when the associated hook passes through the slot. After the top of each of the arms 13 passes therethrough, each of the arms 13 is restored from the bent condition so as to engage the hooks 13a with the associated slot 21. An engaging projection portion 31a is provided in an inner wall of each of the slots 21 such that each of the engaging projection portions 31a is pushed out to the side of the associated slot 21 and fit into the slit 14 by inserting a mating connector 5 into a connecting concave portion 4 to thereby prevent the arms from being inwardly bent.

A connector includes a connector housing which has a pair of side walls, a plurality of terminals which are accommodated in the connector housing, and a pair of metal fixing members. Each metal fixing members includes a board fixing portion and a housing mounting portion. Slots are formed in the side walls. Each housing mounting portion is inserted into each slot from the lower side thereof. The each slot has an upper portion and a lower portion smaller in width than the upper portion. The each slot has a pair of retaining step portions. The each housing mounting portion has a pair of arms. Hooks are formed on upper end portions of the arms. When the housing mounting portion is inserted into the slot, the hooks are engaged with the retaining step portions. A convex portion is formed on an inner wall of the slot.
摘要:
An agitation method for mixing a solution and a solvent to precipitate a solid substance from the solution. The method includes preparing an agitation mixer including an agitation vessel, an impeller rotated in the agitation vessel, and a feed pipe connected to the agitation vessel and having a multiple pipe structure including an outer pipe and an inner pipe arranged in the outer pipe. A shearing clearance is formed in the agitation vessel between the impeller and the feed pipe. The method further includes shearing the solution and the solvent by rotating the impeller to precipitate the solid substance while feeding the solution and the solvent into the shearing clearance from the outer pipe and the inner pipe.
