Title: Melt-treatment of asbestos
Inventor: TSUNEMI TAKESHI
IPC: F23G7/00
Filed: 1989-06-27
Abstract: PURPOSE:To reduce the melt-treatment cost of asbestos to a large extent and to prevent secondary environmental pollution by mixing the dehydrated cake of water treatment sludge with asbestos to subject the resulting mixture to molding treatment and supplying the molded one to a high temp. furnace bed formed of a carbonaceous combustible substance to melt the same under heating. CONSTITUTION:Water treatment sludge is treated with a dehydrator 1 to form a dehydrated cake. Asbestos and said dehydrated cake are compounded so as to adjust moisture to about 10wt.% and sufficiently stirred and mixed by a mixer 2. This mixture is subjected to molding treatment by a molding machine 3 and subjected to melt-treatment under heating on a high temp. furnace bed formed of a carbonaceous combustible substance such as coke in a melting furnace 4. At this time, the water treatment sludge acts as a binder effectively to obtain a sufficiently strong molded product and the scattering of asbestos in the melting furnace 4 can be sufficiently suppressed. Further, the moisture of the mixture of asbestos and the sludge may be merely adjusted to about 10wt.%. By this method, melt-treatment cost can be made inexpensive and secondary environmental pollution due to asbestos can be sufficiently prevented.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To obtain a microscope with a focus detecting means which causes no defocusing even when a body to be detected has a periodic pattern. SOLUTION: When the surface to be detected 23 of a body 24 to be detected deviates greatly from the focus position of a 1st objective 2, focus servo control is performed according to a focus error signal based upon signals from 1st and 4th optical detectors 17 and 20.

Abstract: PURPOSE:To positively restrict pitching phenomenon by correcting a target value for a specified time from the time of detecting the range-position switching so that a phenomenon opposite to a pitching phenomenon being prone to occur due to the range-position switching may be generated. CONSTITUTION:Based on a difference between car height of the front and rear parts of a car body detected by first, second car height detecting means, a detecting means detects an amount of pitch, and a pitching control means controls cylinder devices of the front and rear parts through supply-discharging control valve so that the detected amount of pitch reaches a specified target value, and controls pitching. In this case, when a range-position switching detecting means detects that the range-position is switched from P- or N range to a traveling range, a correction means corrects a target value so that a pitching in the opposite direction to a pitching phenomenon being prone to occur due to the range-position switching is generated for a specified time. Thus, a vehicle can be maintained in a stable position in response to various disturbances.
