    摘要: A pallet with a workpiece mounted thereon is delivered on a pallet carriage, and transferred onto the table of a machine tool which has a different height from the pallet carriage. Lifting mechanisms on the pallet carriage are engaged by respective positioning members in front of the machine tool. The lifting mechanisms are actuated to lift the pallet carriage to position the pallet carriage for transfer of the pallet onto the machine tool table. The pallet is transferred from the pallet carriage onto the machine tool table, half of a predetermined stroke by a first transfer mechanism on the pallet carriage and the remaining half of the stroke by a second transfer mechanism on the machine tool table. The table has vertically movable support rollers for supporting the pallet when it is transferred onto and from the table. When the pallet P is positioned on the table, the vertically movable support rollers are retracted downwardly. When the pallet is transferred onto the machine tool table, clamp units on the machine tool table enter T-shaped slots defined in the lower surface of the pallet, and are actuated to clamp the pallet directly on the table. Since the workpiece on the pallet thus clamped is held in a low position on the machine tool table, the workpiece can be machined by a machining tool that can move freely in a wide space.

C. as in the condition of suspension; (2) adding an acidic or basic compound to said suspension to neutralize said basic or acidic compound catalyst: then after adding dispersion stabilizing resin, further adding an amine salt of organic acid, followed by leaving said suspension to stand to separate into organic and water layers; and isolating the organic layer from the water layer; and (3) removing residual water in the organic layer. The resultant polymer nonaqueous dispersion comprises polymer particles having a total ionic group concentration (I) less than 2.times.10.sup.-5 mol/g particle, a hexane tolerance (HT) from 5 to 40 exclusive and a degree of swelling in acetone (S) less than 10, and used with a binder component comprising a polyol resin and a curing agent for preparing coating compositions.

    摘要: A lubricating oil supply apparatus for a hydraulically operated vehicular transmission has a lubricating oil passage for supplying oil discharged from a discharge port of a pressure control valve which is provided in a hydraulic control circuit of the transmission to lubricating portions thereof as lubricating oil. The lubricating portions are divided into a plurality of groups depending on a change in a required amount of lubricating oil due to a temperature of the transmission. The lubricating oil passage is branched into a plurality of branches corresponding to the groups. The lubricating oil supply apparatus has a choke type of throttle which is disposed in at least one of the branches of the lubricating oil passage.
