Abstract: The present invention provides an apparatus and method of a dock system for launch and recovery of a stowed boat, which is capable of launching and recovering the boat during navigation of a marine vessel at a high headway speed. The launch and recovery apparatus has a stern dock (2) for accommodating the boat (10) therein. The apparatus launches the boat outboard through a stern opening and recovers the boat from the outboard area by entry of the boat into the dock. The apparatus is provided with a conduit device (11) so that seawater surrounding the vessel is drawn through an intake port (12) and is delivered to the dock through an outlet port (13). In the dock, a backward water stream is generated, which is to be discharged outboard through the stern opening.

Abstract: An automatic lathe is capable of rapidly and easily switching between machining of a material with a guide bush and machining of the material without the guide bush. The automatic lathe has a guide bush support table, a support table fixing device for fixing the guide bush support table, a guide member rotatably installed on the guide bush support table so as not to move forward and backward, a guide bush detachably fitted to the tip of the guide member, a driving device for rotating the guide bush, a rotation transmission device for transmitting the rotation of the guide member to the spindle, and a spindle moving device for moving the spindle forward and backward within the guide member. A spindle fixing device positions and fixes the spindle at a specified position on the guide bush support table when the guide bush is removed from the guide member.

Abstract: An automatic lathe is provided which is capable of rapidly and easily switching between machining of a material with a guide bush and machining of the material without the guide bush. The automatic lathe has a head stock (6) and a guide bush support table (1). The head stock (6) is provided with a spindle drive motor (8). The guide bush support table (1) is provided with a guide bush rotating motor (11). There are provided: support table fixing means (15) for positioning and fixing the guide bush support table (1); a guide member (12) rotatably installed on the guide bush support table (1) and regulated so as not to move forward and backward and having a through-hole formed for a spindle (3) to be inserted therein; a guide bush (4) detachably fitted to the tip of the guide member (12); and spindle fixing means (37) for positioning and fixing the spindle (3) on the guide bush support table (1) at a specified position when the guide bush (4) is removed from the guide member (12).
