Abstract: A cushion sub for absorbing both axial and torsional vibration in modern drilling techniques. The cushion sub includes an outer casing connectable at one end to a section of a drill string, usually the upper section being actually the output of the rotary drive, and an inner piston reciprocally mounted in a cylinder within the casing, the piston has a shaft projecting from the other end of the casing connectable to another section of the drill string. The cylinder includes a first cushion device at opposite ends thereof for engagement by the piston to absorb axial vibrations and thereby prevent their transmission between the piston and the cylinder. A spline type connection prevents relative rotation between the piston and the cylinder. The cylinder is mounted for arcuate turning within the casing, but the cylinder has vanes which are interposed between vanes fixed to the casing, and elastomeric material between the vanes of the cylinder and the vanes of the casing absorbs torsional vibrations being transmitted between the cylinder and the casing. An outer surface of the cylinder may be spaced radially inward from an inner surface of the casing to form a closed chamber therebetween containing the interspaced vanes and the elastomeric material between the vanes. The elastomeric material is preferably formed in situ as an integral mass in the chamber by pouring the elastomeric material in a fluid state into the chamber. The cushion sub is of a compact nature with long wear characteristics and is capable of handling the types of forces experienced in advanced drilling techniques and preventing the torsional and axial vibrations developed downhole from being transmitted to the rotary drive.

Title: Information providing system
Inventor: HOSOMI ITARU
IPC: G06F17/30
Filed: 1998-08-17
Granted: 2002-10-15
Abstract: An information providing system is mainly configured by a terminal and an information storage equipment. The terminal is manipulated by a user to issue an information obtainment request, wherein it has a specific output condition, which is defined by a picture output function and/or a sound output function. The information storage equipment extracts a number of digital information elements to suit the information obtainment request, so that the digital information elements are synthesized together into digital information in accordance with a default (information) providing manner, which represents a specific display screen whose screen size and layout are determined in advance. Then, the digital information is transmitted to the terminal, which in turn provides the user with content of the digital information by using pictures and/or sounds. If the default providing manner does not match with the output function of the terminal, the information storage equipment changes the default providing manner by one of change methods, which is selected in consideration of the preset priority. Thus, the digital information elements are synthesized together into the digital information in accordance with the changed providing manner. Incidentally, if the terminal does not have a necessary software module required for outputting the digital information, the terminal downloads it from its resource.
