To provide an industrial method for producing a substituted benzoic acid compound useful as an intermediate of pharmaceutical and agricultural chemicals with high purity and high yield. A compound represented by the formula (II): (wherein Q is a 5- or 6-membered saturated heterocyclic group (the heterocyclic group may be substituted by alkyl) containing one or two of at least one type of hetero atom selected from the group consisting of an oxygen atom and a sulfur atom, or dialkoxymethyl, T is trifluoromethyl, nitro, cyano, &#x2014;SOA, &#x2014;SOA, &#x2014;PO(OA)(OA), &#x2014;COA, &#x2014;COAor &#x2014;CONAA, each of Aand Awhich are independent of each other, is a hydrogen atom, alkyl or haloalkyl, X is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, dialkylaminosulfonyl, di(haloalkyl)aminosulfonyl, nitro or cyano, Y is a chlorine atom, a bromine atom or an iodine atom, and n is an integer of from 1 to 6), carbon monoxide and a compound represented by the formula R&#x2014;OH (wherein R is alkyl) are reacted, followed by hydrolysis to obtain a compound represented by the formula (I): wherein Q, T, X and n are as defined above.

Method for producing a substituted benzoic acid compound

A fan apparatus includes an impeller, a motor rotating the impeller, a plurality of stator blades arranged opposite to the impeller in an axial direction. The stator blades each include a curved portion at which the stator blades each are curved with respect to the direction in which the stator blades extend.

Fan apparatus

A centrifugal fan includes a motor having an impeller and a housing for accommodating the motor. The housing has a sidewall surrounding an outer circumference of the impeller. An air inlet is formed in the housing and opposed to a center portion of the impeller. An air outlet is formed in the sidewall of the housing and opposed to an outer surface of the impeller. The housing includes a housing body and a housing cover. The housing body has a bottom with the motor secured thereon. The housing cover, formed by a pressed metal member, has an upper part and a cover sidewall extending from the upper part toward the bottom of the housing body and forming at least a part of the sidewall of the housing.

Centrifugal fan

An arrangement of a low air inlet and a circuit for driving a torque generator in an ultra-compact centrifugal fan is disclosed. In the ultra-compact centrifugal fan, a region occupied by the circuit is not completely arranged radially inside a cup-shaped portion to which an impeller is attached. At least a part of the low air inlet provided on a bottom of a housing of the centrifugal fan is arranged in a range of predetermined angle in an imaginary ring-shaped portion surrounding a base portion covered by the cup-shaped portion. A part of the circuit, that is not covered by the cup-shaped portion, is arranged upstream of the range of the predetermined angle in a flowing direction of airflow.

In manufacturing of the stator unitaccording to one preferred embodiment of the present invention, a plurality of terminal pins are arranged in an axially spaced manner from a plurality of the coils during a twining process of the wires from the coilsto the terminal pins. Then, after the wire is twined to the terminal pins, the terminal pins connected to the coils are moved along the outer side face of the sleeve housing, functioning to as a guide portionfor the terminal pins. By virtue of the configuration, the terminal pinsmay be approximated to the coils without applying the tension on wire, and the stator unit may be made thin with preventing the open circuit of the wires.
