Title: Installing method for geomagnetic sensor
Inventor: KINOUCHI TAKASHI
IPC: G01V3/40
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect geomagnetism which is normally precise by eliminating influences of transformed geomagnetism by inclining and installing a geomagnetic sensor to an angle vertical to a vertical element of the geomagnetism that is transformed by a physical object of high magnetic permeability. SOLUTION: A geomagnetic sensor 2 is made to incline to an angle vertical to a direction (an arrow y) of a vertical element of geomagnetism transformed by a magnetic shield 3 and installed. Thus, even if the vertical element of the geomagnetism is transformed, this element ceases to actuate a detection coil of the geomagnetic sensor 2 as a horizontal element and precise detection of the horizontal element of the geomagnetism is enabled. Therefore, when a physical object of high magnetic permeability such as the magnetic shield 3 and the geomagnetism sensor 2 are arranged side by side, it is possible to easily solve such a problem that a direction of neighborhood geomagnetism is transformed by an influence of the physical object of high permeability and that the precise detection of the geomagnetism is not enabled by the geomagnetic sensor 2 in a range that is influenced.

Title: Positioning method for device for supplying and discharging workpiece to be sewn
Inventor: NITSUTOU TAKASHI
IPC: D05B33/00
Filed: 1989-07-18
Abstract: PURPOSE:To enable positioning with small impulse only by switching a valve by driving a rotor through a one way clutch by an air actuator, stopping the drive before a prescribed stop position, rotating the rotor by inertia and protruding a stopper into the range of the rotation before the rotor arrives at the stop position. CONSTITUTION:Since a rotor 2a is released from the drive by the air actuator before the prescribed positioning and continues the rotation by the inertia, the speed of the rotor is lowered when a projection 12 is abutted against a first stopper 13. Further, since the first stopper 13 is turned to right against a spring 16 by the abutting and afterwards turned to left by the energizing force of the spring 16 and the projection 12 is pushed back to the prescribed stop position, the impulse is reduced at the time of stop. Thus, positioning can be executed while relaxing the impulse.

Title: Device for clamping second machine section movably arranged to first machine section
Inventor: FURANTSU KAAGERAA
IPC: B23Q1/28
Filed: 1985-08-23
Abstract: We are dealing with a mechanism for clamping a second machine part 4 which is supported movably with respect to a first machine part 2. A clamping bar 28, which extends in the direction of movement is arranged on the second machine part 4, on which clamping bar can be clamped a clamping member 32 which is supported freely movably in directions transverse to the direction of movement of the first machine part, but otherwise clearance free. Since the clamping member 22 is as a whole freely movable in directions transverse to the direction of movement, no reactive forces whatsoever are created in the direction of movement during the clamping operation. The inventive clamping mechanism is preferably used in feed-movable spindle sleeves (tail spindles) in order to assure a secure clamping in an axial direction and in a peripheral direction, without producing forces which act transversely to the spindle axis.
