Title: Method of removing coating films
Inventor: TERADA MASAHIRO
IPC: C08J7/02
Filed: 1993-09-24
Abstract: The improved method of removing the coating films on resin substrates comprises first treating the resin substrates in an aqueous alkali solution with a concentration of 0.1 wt% or more at a temperature of 110 DEG C or more which is lower than the melting point of the substrates and then polishing the surfaces of the substrates by either bringing them into contact with each other in suitable equipment such as a screw feeder, or using an abrasive in suitable equipment such as a high-speed vessel type stirrer, or subjecting the substrates to a liquid honing process. The method assures complete removal of the coating films on the resin substrates and yet the stripped substrates can be recycled to another industrial use. The method is used for removing paint films from polypropylene for use in automobile bumpers.

Title: Computational structures for the frequency-domain analysis of signals and       systems
Inventor: SUNDARARAJAN DURAISAMY
IPC: G06F17/14
Filed: 1993-11-05
Abstract: The present invention allows analysis of signals and systems by providing a family of structures for the computation of the discrete Fourier transform (DFT) of a discrete signal of N samples. A member of this set of computational structures is characterized by two parameters, u and v, where u (u = 2<r>,r = 1,2,..,(log2 N) - 1) specifies the size of each data vector applied at the two input nodes of a butterfly and v represents the number of consecutive stages of the structure whose multiplication operations are merged partially or fully. The nature of the problem of computing the DFT is such that the sub-family of the structures with u = 2 suits best for achieving its solution. These structures have the features that eliminate or reduce the drawbacks of the existing structures while retaining their simplicity and regularity. A comprehensive description of the two most useful structures from this sub-family along with their hardware and software implementations is presented. The hardware includes a pipe-lined arrangement of adders, subtracters, multipliers and plus-minus units. <IMAGE>

Title: Sensing of hydraulic cylinder piston position using electromagnetic waves
Inventor: LARK WAYNE W
IPC: G01B7/00
Filed: 1996-04-01
Abstract: In a piston position sensing system using electromagnetic waves in the fluid in a hydraulic cylinder 10, the ability to detect selected resonant frequencies associated with the position of the piston 14 is improved by positioning the electric signal input and output probes 17, 18 with substantially 90 degree separation around the circumferential periphery of the cylinder to suppress coupling into unwanted modes that diminish detectability of particular resonant frequency signals. In a coaxial sensing system as shown, "dummy" probes 19, 20 at substantially 90 degree separation to each other and to the input and output probes operate to improve symmetry and resonance shape and to suppress unwanted modes.

Title: A method of tracing errors in communication between a telephone set and a remote server
Inventor: CHANG JACKSON
IPC: H04M3/22
Filed: 1996-12-30
Abstract: A method of recording the bi-directional communication between a customer premises equipment (CPE) and a server of a stored program controlled system (SPCS) in an analog display services interface (ADSI) for facilitating the troubleshooting therein is disclosed. The present invention includes accessing the telephone set by a user, therefore initiating the communication between the telephone set and the server. After receiving an alerting signal 52 from the server, the alerting signal and the corresponding received time of the alerting signal are recorded into a trace area in the telephone set. A first acknowledgment signal 54 is sent to the server after the alerting signal is recognized, and the first acknowledgment signal is then recorded in the trace area. At least one message 56 is sent from the server, and then the message, a start received time and an end received time of the message are recorded into the trace area and a message buffer. Finally, a second acknowledgment signal D1 is sent to the server, and the second acknowledgment signal is then recorded in the trace area. The stored data can then be recalled and viewed on a liquid crystal display of the telephone set so that the user can trace through the data and detect any faults which may have occurred during communication.
