Patent TW-394722-B (TW)
Title: Removable bond for abrasive tool
Inventor: SHIUE REN-KAI
IPC: B24D3/06
Filed: 1997-08-20
Granted: 2000-06-21
Abstract: A bond for a metal single layer abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior ro reuse. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond. Hence, the bond is particularly useful for the manufacture abrasive wheels employed in the construction industry. The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method of brazing the bond incorporates heating  the bond composition to a temperature at most about 880 DEG to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900 DEG to dissolve the copper. The bond can also include an about 10-200 mu m thick barrier layer of copper coating the cutting surface between the core and the bond composition.

Title: Correlation detecting apparatus, its detecting method and communication apparatus and its communication method
Inventor: USUI TAKASHI
IPC: H04J11/00
Filed: 1998-08-24
Granted: 2000-11-01
Abstract: To provide a correlation detecting apparatus which is capable of securely detecting the M sequence code forming a reference for timing even when a plurality of signals with different amplitudes are time division multiplexed. The matched filter (82) for detecting the predetermined code from the received signal, the average amplitude detector circuit (83) for detecting the average amplitude of received signal, and the divider circuit (84) for normalizing the output of matched filter (82) by the output of average amplitude detector circuit 83 are provided. The output of matched filter (82) normalized by the divider circuit (84) is compared with the threshold value for outputting the correlation detecting signal. When the received signal level is large, the output level of matched filter (82) becomes large. However, in this case because the average amplitude of received signal becomes also large, the divided value of output level of matched filter (82) by the output level of average amplitude detector circuit (83) makes almost no change. In contrast to this, the output level of matched filter when the M sequence is received remains nearly costant irrespective of the input signal level. Therefore, the received signal of M sequence can be detected without fail from the output of comparator circuit (85).
