Title: Removing device for closing cock of heat transfer pipe
Inventor: KUROKAWA HIDEYUKI
IPC: B23P19/04
Filed: 1989-12-05
Abstract: PURPOSE:To shorten the length of a core-boosting, closing cock-pullout cylinder and the overall height of a removing device by providing below the core- boosting, closing-cock pullout cylinder a turning movement means for rotating a mandrel from one side. CONSTITUTION:After a mandrel 5 is engaged in a closing cock C, a main body lifting cylinder is actuated so that a core-boosting, closing cock-pullout cylinder 2 falls by the amount of the stroke by which the core is boosted. Thereafter, a rotary actuator 4 is actuated and the cylinder main body of the core-boosting, closing cock-pullout cylinder 2 is communicated with a core pushing bar 8 and a high pressure fluid is introduced into the core-boosting, closing cock- drawing cylinder 2. The cylinder main body and the core pushing bar 8 are raised relative to a piston 2a by the amount of the stroke by which the core is boosted, the piston 2a transmitting reaction forces to the mandrel 5 being engaged in the closing cock C and suspended; a core (d) sealingly fixing the closing cock C in a heat transfer pipe (b) is thereby boosted and released.

Title: Free curved face machining tool
Inventor: OMORI HITOSHI
IPC: B24B13/01
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a free curved face machining tool in which the peripheral speed of its axis does not become zero (0) and therefore a free curved face can be machined to a high quality with high accuracy by use of a versatile triaxial NC machining device. SOLUTION: A free curved face machining tool 10, which rotates about an axis (z) to bring its lower end into contact with a surface to be machined to machine the surface, has a spherical tool 12 having a spherical face machining part 13 on its underside and has a support bearing 14 passing through the center O of a spherical face and supporting the spherical tool on a rotation axis (a) which is different from said axis. The tool 10 also includes a rotation means 16 (e.g., turbine) for rotating the spherical tool around its own rotation axis.  Thus even if the spherical face machining part comes in contact with the surface to be machined at the position of the axis (radius 0) of the tool, the spherical face machining part rotates about the own rotation axis (a) different from the axis (z) and the peripheral speed of the axis does not become zero (0), so that a free curved face can be machined to a high quality with high accuracy by use of a versatile triaxial NC machining device.

Filed: 1988-12-14
Abstract: PURPOSE: To achieve rapid filtration of coffee by boiling a mixture of coffee powder and water in a case by applying a microwave thereto and forcing the coffee extract to flow through the filter paper by the pressure evolved in the case. CONSTITUTION: A receiver 1 with an open mouth for a filtrate is prepared, and an almost tight case 4 is settled removably on the receiver 1.
