PURPOSE:To speed up measurement by removing a DC signal level included in an output from a photodetecting element from the output when the DC signal level is larger than a prescribed value. CONSTITUTION:An output from an OP amplifier which is determined is accordance with the direction of current flowing into a feedback system 46 is detected by a comparator 52 to discharge a capacitor 48. The char...

PURPOSE:To reduce the frequency of system down of an electric power supply controlling device with a microprocessor due to a runaway of the microprocessor, by stopping the runaway even when the microprocessor runs away. CONSTITUTION:Clear signals which clear a timer 12 are sent out from a microprocessor 11 at a regular cycle. Since the controlling function of the microprocessor 11 gets out of orde...

The inventive sheet has a content of mineral fibers greater than 70 wt. % of the total weight of fibers and binder, and has a density between 400 and 1600 kg/m3. The sheet can be employed in particular as an architectural structural wall facing, as a component of a composite insulating panel, etc., and i...

PURPOSE:To realize the flying start-stop through a slight design change without adding any special additional function by providing a means spacing a disc and a slider during the stop of the disc and changing said space to a required value. CONSTITUTION:The moving direction P of an actuator to the medium face of the disc 1 is tilted slightly as a means changing the distance between the disc 1 and ...

PURPOSE:To facilitate the inspection of connection parts at the step of connection between external connection members and the titled carrier by leading a bonding pattern out of the cap. CONSTITUTION:Said carrier 7 has the bonding pattern 3 led out of the cap 2', and the extension of the pattern 3 being made as an inspection pattern 11. Therefore, the contact of a contactor for conducting inspecti...

Activated sludge wastewater treatment process for removing phosphate from BOD-containing wastewater in which phosphate-enriched sludge formed in the aeration zone is settled in a phosphate stripping zone under anaerobic conditions to cause release of phosphate from the sludge solids. The released phosphate is countercurrently stripped from the sludge in the stripping zone by a low phosphate, low s...

PURPOSE:To obtain a fault plane image having high image quality by inserting a pair of slice magnetic field coils between electromagnets of an ordinal fault plane position control device photographing plural fault plane images at once. CONSTITUTION:A pair of slice magnetic field coils 20 changing the intensity of a DC magnetic field generated by the electromagnets 11 and a slice magnetic field dri...

An armoured assault car has a central chassis articulated at each of its two ends on a bogie chassis by a transverse shaft and a longitudinal shaft. At least one monitoring device acts between the central chassis and the chassis of one of the bogies for controlling the relative transverse slope of the central chassis relative to the bogie chassis about the longitudinal axis of the car. The gun tur...

The present invention has for its object an off-road vehicle comprising a central chassis at each end of which is articulated about a transverse axis, a bogie chassis with a jack acting between the central chassis and each bogie chassis to permit regulation of their relative longitudinal inclinations, the transverse axis of articulation of each bogie chassis on the central chassis being located in...

A method of securing a fixing element such as a dowel in a drillhole in a rock mass wherein the element is grouted in position with calcium sulphate hemihydrate plaster (preferably alpha gypsum) gauged with a solution of a water-soluble salt of carboxy methyl cellulose.

PURPOSE:To avoid the system down of an electric power supply controlling device with a microcomputer and, at the same time, to improve the noise margin, by installing an oscillating circuit which repeatedly generates set/reset signals at a regular cycle to the power supply controlling device. CONSTITUTION:An oscillating circuit 7 which generates a signal that resets a microprocessor 5 by means of ...

Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a tin component, a cobalt component and a halogen component with a porous carrier material. The platinum group component, tin component, cobalt component, and halogen component ...

Surface treatment of stones such as marbles, granites and the like by means of impregnating the stone with a liquid protector agent which may be a monomer such as styrene, methyl methacrylate and the like for forming the acrylic resin or a lower polymer thereof so as to penetrate in crystal grain gaps of the stone, and then heating the stone for polymerizing or copolymerizing of the impregnated ag...

A diamond with an inscription comprises a diamond gem structure having an outer surface cut and polished into a specific shape and a microscopic inscription formed at a specific position on the outer surface of the diamond gem structure. The inscription has a pattern indicating the results of expert appraisal of the diamond gem structure. The inscription may be formed by a method including cleanin...

A sanitary napkin. The sanitary napkin comprises a central absorbent pad and flaps extending from each longitudinal edge of the central absorbent pad. The body of each flap contains a flexible axis about which the flap can fold on itself. The sanitary napkin preferentially bends at the line of juncture between each flap and the longitudinal edge of the central absorbent pad. When the sanitary napk...

Rubber is recovered for re-use e.g. from scrap pneumatic tires by briefly raising a surface of the tire to a high temperature and then rasping the heat-treated surface. Tires reinforced either with a textile or a steel ply can first be parted on opposite sides of the breaker structure. A machine is provided which accepts pieces of vulcanized material and progressively reduces them to heat-treated ...
