摘要:
The present invention provides a method for producing an optically active 4-[.alpha.-hydroxy-5-(1-imidazolyl)-2-methylbenzyl]-3,5-dimethylbenzoic acid or a pharmaceutically acceptable salt thereof, which includes subjecting a compound of the formula (I) wherein each symbol in the formula is as defined in the specification, to optical resolution by fractional crystallization to give an optically active compound thereof and subjecting the compound to hydrolysis reaction. According to this method, a resolution method useful for industrial large-scale production of the optically active compound of 4-[.alpha.-hydroxy-5-(1-imidazolyl)-2-methylbenzyl]-3,5-dimethylbenzoic acid, which is useful as a thromboxane synthetase inhibitor and an agent for the prophylaxis and treatment of diabetic complications, can be obtained.

A method of fitting a rubber stopper for a water-proof connector terminal onto an end portion of an electric wire includes the steps of: successively feeding a group of rubber stoppers aligned in a row in a state wherein each of the rubber stoppers has its longitudinal axis extending vertically; transferring each of the rubber stoppers into a stopper housing portion; retaining the electric wire disposed on an imaginary line passing through the center of the stopper housing portion; and press-fitting the wire into the rubber stopper, whereby the rubber stoppers are successively and continuously fitted on the respective wires. Also disclosed is an apparatus which may be suitably employed to carry out the above-described method. The apparatus includes an aligned stopper successively feeding section, a stopper transfer section, a rotary conveyor section, and a wire press-fitting section. The apparatus is further provided with an automatic control circuit adapted to allow the respective operations of the above-described secitons to be sequentially interlocked with each other.

An apparatus and method are provided to widen a woven sheath of a wire. The apparatus and method are operative to punch an exposed woven sheath S3 in radial directions by a pair of punches 31b to deform and widen the woven sheath. The woven sheath S3 can be deformed and widened easily even if it has a multi-layer construction.

Recesses 12 are formed on an upper surface 10a of a turntable 10 detachably mountable on a support member 20. The recesses 12 are arranged at a pitch of a specified angle .theta. on a plurality of concentric circles C1 to C4 centered on a longitudinal axis 11. The turntable 10 is slid along an x-axis by an air cylinder 80 and is intermittently rotated by the specified angle .theta. by an air motor 40. In this way, a desired recess 12 can be moved to a receiving position P. The waterproof plugs can be securely supplied. A preparation for changing the kind of the waterproof can be made only by replacing the turntable, with the result that the preparation can be easily made within a short period of time.

A terminal temporary holding jig (J) is provided for a later-inserted terminal (T). The terminal temporary holding jig (J) includes a terminal holder (1) secured to a base (B) of an automatic terminal inserting apparatus. A lid (2) is provided for opening and closing terminal insertion grooves (5) that extend in forward and backward directions in the terminal holder (1). The lid (2) can be attached magnetically in a closed condition on the terminal holder (1). A locking member (9) is provided in the lid (2) and includes a leaf spring with saw teeth that project obliquely backward into the terminal insertion grooves (5). A later-inserted terminal (T) can be inserted through a front end opening of the terminal insertion groove (5) in this state, and can be locked in the terminal insertion groove (5) by the engagement of a step “b” of the terminal (T) with the leading end of the locking member (9). The terminal (T) is taken out by rotating the base (B) into an inverted position, opening the lid (2) and pushing the terminal (T) and the wire (A) down together.
