Title: Semiconductor integrated circuit
Inventor: KAWAHARA TAKAYUKI
IPC: G11C11/407
Filed: 2000-06-16
Abstract: PROBLEM TO BE SOLVED: To refine a CMOS circuit and to reduce current consumption at the time of standby, even if a sub-threshold current becomes large by setting a current flowing to plural CMOS circuits at standby, not through a sub-threshold current but by a leakage current small in a switching transistor. SOLUTION: A switching control terminal T1 is set at low level, at a standby, a switch S1 using a MOS transistor is turned, off, a leakage current of the switch S1 is set smaller than a sub-threshold current of many circuit of which only a few operate Ci(Ci=1 to n) at one time. Therefore, a maximum current to the circuit Ci which uses the CMOS transistor, having a low threshold voltage from a high potential side power source VC is the leakage current to the switching circuit S1. That is, the current flowing the circuit Ci is decided not by the sub-threshold current of the circuit Ci but by the leakage current of the small switching circuit S1. Thus, current consumption at standby time becomes small.

IPC: C23F1/26
Filed: 2000-06-23
Abstract: PROBLEM TO BE SOLVED: To solve a problem that the shape of a molybdenum cross section after the completion of etching becomes a wedge one, the coverage property of a film formed on the upper layer of molybdenum in a subsequent process is deteriorated and it becomes a cause for raising the defect of disconnection and the like, since the difference of an etching rate exists between a molybdenum oxide film existed on the surface of molybdenum and pure molybdenum below it when etching liquid where phosphoric acid, nitric acid, acetic acid and water are mixed is used if a wiring pattern is formed by immersing molybdenum in etching liquid and etching it.

Title: Misfire detecting system and method, employing recursive median filter
Inventor: VARADY ARTHUR JOSEPH
IPC: F02B75/18
Filed: 2000-06-26
Abstract: PROBLEM TO BE SOLVED: To provide an improved signal-processing system and its method for detecting a misfire in an engine control system high in data speed. SOLUTION: Including the process of generating a speed signal high in data speed that represents torque behavior of an engine, the method for detecting a misfire of separate gas cylinder events in an internal combustion engine performs filter processing of the speed signal, and separates each thereof into a plurality of non-hybrid uniform data sets that represent a similar portion of an internal combustion engine cycle. A median filter is applied to each of a plurality of non-hybrid uniform data sets. The data sets are thus normalized in accordance with the applied recursive median filter so as to be centralized about a relative zero value. This centralizing action permits signal re- synthesization after the filter processing, thereby monitoring any deviation characteristics present in the signal.  The generated signal is compared with a threshold so as to determine whether an accidental fire has occurred or not.
