Patent CA-2232697-A1 (CA)
Inventor: SUGIKAWA HIROFUMI
IPC: H01M4/80
Filed: 1998-03-19
Abstract: Metal powders are spread on a feeding belt or a supporting sheet which is continuously fed.  Then, the feeding belt or the supporting sheet on which the metal powders have been spread is passed between a pair of rolling rollers to roll them at a required strength of pressure to leave fine gaps between the metal powders adjacent to each other.  Thereafter, a resulting metal sheet is passed through a sintering oven to integrate the metal powders to each other so as to form a porous metal sheet having fine pores consisting of the gaps.  It is possible to spread the metal powders on the rolling roller directly or a mixture of sublimable fine fragments and the metal powders thereon.  Further, it is possible to form a solid metal sheet, namely, a metal sheet having no pores formed thereon by setting the strength of pressure of the rolling roller to a high one.

Title: A method for providing user global object name space in a multi-user operating system
Inventor: DISCAVAGE MICHAEL J
IPC: G06F9/46
Filed: 1996-10-04
Abstract: A method, suitable for use in client/server system, which allows multiple copies of a single-user application to run simultaneously in a multi-user operating system without modification of the single-user program, by modifying existing operating system methods used for object name creation, lookup, and deletion. The method creates a user global context by labeling each instance of the single-user application with a user identifier (name) that defines a single-user name space in which each labeled object is only available to the named user. In addition, the single-user server process is allowed to impersonate the client for allowing the server to access the named resources of the single-user name space. A coexisting system global context is also created by marking system global named resources.

Title: Method and circuit arrangement for producing a ring voltage for electronic subscriber circuits
Inventor: STIAWA RALF
IPC: H03F1/02
Filed: 1998-09-11
Abstract: To limit the development of heat in subscriber circuits which exist in large numbers in telecommunication systems, the power loss of these circuits must be kept as small as possible.  The invention achieves that the power loss of the power amplifier (1), which amplifies a low amplitude ring voltage, is reduced in that the operating voltage (U Bi) of the power amplifier (1) is not constant as is the well known custom, but that it is controlled.  This takes place through a simple switching controller (2), so that in large time segments the operating voltage (U Bi) is only insignificantly greater (more negative) than the ring voltage (U RA).

Title: Arm-operated sound effect device for plucked instrument
Inventor: O'CONNELL PETER D
IPC: G10H3/18
Filed: 1998-10-15
Abstract: Electric and electro-acoustic guitars are known to be used in conjunction with effect pedals. In this case specifically with a tone (wha wha) or volume pedal. These pedals are 10 cm wide by 25 cm long by 4.5 cm deep with a pivoting pad on top and are usually positioned on the floor in front of the guitar player. The guitar player, by moving his or her foot on top of the pad controls the volume or tone of the guitar signal. In this invention, a guitar has a smaller (10 cm long by 10 cm wide by 3 cm deep) version of such a pedal attached to the front part of its body, in a position so that the forearm of the strumming hand rests on the pivoting pad. This way the forearm can operate the pedal. The pivot axis is along the line of the two corners of the pad closest to the strings (perpendicular to the strumming forearm). Two expansion springs underneath the pivoting pad at the opposite two corners (near the strumming arm's elbow) provide just enough resistance so that by moving the forearm of the strumming hand towards and away from the pedals (towards and away from the front of the body of the guitar) the level of volume or graduation of tone (depending on which effect function the pedal serves) can be controlled while strumming by a simple movement of the forearm.

Inventor: GILCHRIST RODNEY D
IPC: G16B30/10
Filed: 1997-06-26
Abstract: Data traces from four channels of an automated electrophoresis detection apparatus are aligned by identifying peaks in each of the four data traces; optionally normalizing the data traces to achieve a uniform peak height; combining the four data traces in an initial alignment; and determining coefficients of shift and stretch for selected data points within each data trace. The coefficients are determined by optimizing a cost function which reflects the extent of overlap of peaks in the combined normalized data traces to which the coefficients have been applied. The cost function is optimized when the extent of overlap is at a minimum. The coefficients are then used to generate a warp function for each data trace. These warp functions are applied to their respective data traces to produce four warped data traces which are aligned to form an aligned data set. The aligned data set may be displayed on a video screen of a sequencing apparatus, or may be used as the data set for a base-calling process.

Title: Method and apparatus for tailored distortion of a signal prior to amplification
Inventor: VANNUCCI GIOVANNI
IPC: H04J3/00
Filed: 1999-02-23
Abstract: In order to minimize the adverse effects of RF signal nonlinearities during amplification, especially the deleterious effects of signal clipping which may cause uncontrolled out-of-band emissions known as "spectral regrowth", the specification relates to a device and a method for intentionally distorting a radio frequency (RF) signal in a "tailored manner", prior to the amplification of the RF signal. The device monitors the amplitude of a RF signal at the inlet of a "tailored" distorter. A  modifying signal waveform is generated whenever the amplitude of the monitored RF signal is greater than a threshold value. The RF signal is delayed to account for signal processing time associated with the generation of the modifying signal waveform. The generated modifying signal waveform is then summed with the delayed RF signal, thereby forming an intentionally distorted version of the original RF signal. The distorted signal is conveyed to a RF signal amplifier for amplification. The modifying waveform is chosen so as to reduce the amplitude of the RF signal peak to a value that does not exceed the clipping threshold. Furthermore, the modifying waveform is chosen ("tailored") to be less harmful than the effects of the clipping distortion it replaces. The modifying waveform may be completely in-band, out-of-band, or have components of each, depending upon the specific implementation and the desired power spectrum. The process is compatible with current predistortion techniques and may used in conjunction with, or in lieu, of signal predistortion.
