Title: Water hammer preventing device
Inventor: SAKANE TOYOHIKO
IPC: F16L55/04
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To surely prevent a water hammer generated in a plug opening/closing time in a water-supply pipe and to simplify structure and assembly of a water hammer preventing device by pressing and deforming a rubber outer cylinder housing a rubber inner cylinder via a rib formed on the outside face of the inner cylinder according to expansion of the inner cylinder. SOLUTION: In a rubber inner cylinder 1 connected to a pipe via a nipple 3, its inside 1c functions as a pressure chamber when a water hammer is generated. If the water hammer is small, the pressure chamber 1c is expanded within a range, in which a rib 1a formed on the outside face of the inner cylinder 1 is brought into contact with the inside face of a rubber outer cylinder 2, that is, within a range of a clearance K for absorbing the water hammer. At the same time, the water hammer is also absorbed in an air layer 6 formed between the inner cylinder 1 and the outer cylinder 2. If the water hammer is great, the outer cylinder 2 is pressed from its inside face by means of the rib 1a so as to be deformed after the pressure chamber 1c is expanded, and consequently, the water hammer is absorbed.  That is, the outer cylinder 2 is deformed within a range of a clearance (k) between a casing 4 and it.

Title: Extrapolative reconstitution method for herical scanning
Inventor: KEBIN FURANKURIN KINGU
IPC: G06T11/00
Filed: 1990-11-13
Abstract: PURPOSE: To acquire the projection data for a single piece of slice image at a short z-axis distance by collecting the data of two partial projection sets for each side of the slice plane acquired by 180-deg. rotation of a gantry. CONSTITUTION: The angular position θ of a gantry 16 relative to an object to be image processed 12 is arbitrarily assumed to be zero when the control ray 20 of sector-form beams is down facing vertically. Because coupled with a control module 48 through a slip ring 50, the gantry 16 can continuously rotate freely for a larger angle range than 360deg. for acquiring the projection data. The angular position of the gantry and the z-axis position on the imaging plane relative to the object to be image processed vary continually during data acquisition of each tomographic projection set. Therefore, the arrow 20 draws a spiral within the object along the z-axis.  If the situation allows obtaining at least a minimum gantry rotation for an angle corresponding to the sum of 180deg. and the sector-form beam angle, it is practicable to produce a tomographic image reconstructed from the projection data acquired with this rotation.
