Filed: 1989-12-14
Abstract: PURPOSE:To enlarge the surface areas, increase the discharging characteristic, and prolong the lifetime of battery by forming a metal electrode from a group of metal particles having a number of minute gaps for flowing-through of the electrolytic solution, and accommodating it in a conductive porous vessel. CONSTITUTION:A metal electrode 3 is formed from a group of metal particles 3a having a number of minute gaps 3b, which serve for flowing-through of the electrolytic solution, and this is accommodated in a conductive porous vessel 4. Therein the surface areas contacting the electrolytic solution can be increased compared with a metal electrode consisting of an ordinary plate, which enhances the discharging characteristic accordingly. Because this group of metal particles 3a is accommodated in porous vessel 4, eventually generated corrosions on them remain within the porous vessel 4, and they serve the reactions to the last stage to achieve long lifetime of the battery. This permits increase in the contacting areas of the metal electrode 3 with the electrolytic solution and enhances the discharging characteristics accordingly, and thus the battery life can be prolonged.

Abstract: PROBLEM TO BE SOLVED: To reduce an electron trap or an interface level by using inert gas which is a compound not containing an oxygen atom and not having the coupling (N-H) of a nitrogen atom and a hydrogen atom, and produces nitrogen in the form of a single atom at dissociation. SOLUTION: A silicon substrate 1 is installed in a reactive tube for oxidation and nitriding kept in atmosphere where oxygen and moisture is reduced to the utmost. In case of a low-resistance heating furnace, the temperature within a furnace is made 700-900 deg.C and in case of lamp heating, the water temperature is made 700-1100 deg.C. Then, inert gas such as triaryl amine or nitrogen gas (N2 ) including this, argon gas (Ar), etc., is introduced into a reactive tube. Hereby, nitrogen in the form of a single atom is produced by thermal dissociation, and the surface of the silicon substrate 1 is nitrided. Since there is no natural oxide film before nitriding, a nitride film 2 good in film equality is made by this nitriding.

IPC: G01M17/007
Filed: 1994-12-27
Abstract: PURPOSE: To shorten a response time without increasing the failure probability of fault detection by resetting a time constant to the minimum so as to initialize, gradually increasing the same to the maximum value, and comparing the processed value of a geometrical moving average method (GMA) and a threshold so as to generate a fault signal. CONSTITUTION: Signals directly obtained from a sensor or a component are input to a parameter arithmetic circuit 14 so as to compute, for instance, a containing oxygen amount to feed to a GMA filter 15 as a numerical data row of a performance parameter such as a catalytic efficiency. While a time constant τ is initialized to the minimum value and is fed to the GMA filter 15 by a time constant block 16 so that a geometrical moving average value is determined. A GMA output is input to one side of a comparator 17 so as to compare the GMA output and a threshold, and when the average value exceeds the threshold, a fault signal is output by the comparator 17. Increment, filter processing, comparison, and generation of the signal are repeated until the time constant τ reaches the maximum value.
