IPC: H01L21/285
Filed: 1990-08-17
Abstract: PURPOSE:To form a connecting electrode whose reliability is high without increasing the number of processes by executing the following: a process to apply a high-melting-point metal silicide to a contact hole and to a polycrystalline silicon film; and a process to etch back and remove the high- melting-point metal silicide and the polycrystalline silicon film applied to their surface. CONSTITUTION:A tungsten silicide (WSix; a high-melting-point metal silicide) 19 is applied, by a CVD method, to the inside of a contact hole and to a polycrystalline silicon film. Then, the tungsten silicide 18 on the surface and the polycrystalline silicon film 16 are etched back and removed. Thereby, the polycrystalline silicon film 16 is removed wholly; the tungsten silicide 18 is formed in a state that it protrudes a little at the upper part of the contact hole. After that, an aluminum interconnection which is connected to the contact hole is formed. It is possible to form the interconnection which is stable and whose reliability is high.

IPC: B06B3/00
Filed: 1990-08-17
Abstract: PURPOSE:To prevent a structure and a sensor from damage by providing a flanged rod including the rod part formed integrally with a flange part to be mounted to an exciting device and a flexible rod including thin plate parts. CONSTITUTION:The vibration is transmitted from an exciting device through a flanged rod 20 and then through a rod part 22 to an adjusting rod 40 and, from there, it is transmitted as such to a rod part 34 of a flexible rod 30. The vibration is then transmitted from the rod part 34 of the flexible rod 30 through thin plate parts 33 and 32 to a threaded part 31 so as to impart the vibration to a structure. At this time, since all the parts are threadedly fastened together, unnecessary gaps can be removed and the vibration can be appropriately transmitted from the exciting device to a sensor provided on the structure, resulting in the improvement of the detecting accuracy of the sensor. Also, since the thin plate parts 32 and 33 present buckling phenomenon to the vibratory components in the directions eccentric relative to their respective plane directions, they can maintain their function as a mechanical fuse and damages to the structure and sensor can be avoided.

Abstract: PROBLEM TO BE SOLVED: To provide a furnace, incinerating simultaneously with melting wastes without effecting any special working or selection of the wastes and without adding any assistant fuel. SOLUTION: A waste incinerating and melting furnace is provided with a dry distillation furnace 1, treating wastes through dry distillation, an ash melting furnace 5, producing molten ash from dry distillation coal produced in the dry distillation furnace 1, and a secondary combustion chamber 7, provided above the ash melting furnace 5 through a choking section to burn unburnt constituents. The choking section is provided at the upper part of the ash melting furnace 5 whereby the operation of the ash melting furnace 5 will not be affected by the value of a temperature in the secondary combustion chamber 7.  Accordingly, dry distillation coal, comparatively stabilized in the composition thereof among the dry distillation products, is supplied into the ash melting furnace 5 and the dry distillation gas, largely fluctuated in composition, is supplied into the secondary combustion chamber 7 whereby the melting furnace can be operated stably. When wastes, containing much amount of moisture, are supplied suddenly into a system, for example, the moisture is transferred into dry distillation gas whereby the amount of gas is increased thereby reducing the amount of generation of heat only. The composition of the dry distillation coal is not fluctuated whereby the burning condition of the molten ash constituent, weak against the fluctuation, will not be fluctuated.
