PURPOSE:To detect quickly an abnormal state by a small hardware quantity, by executing the comparison and collation of key data information in a key data field provided on each micro-instruction, and key data information in a key register. CONSTITUTION:A key data is provided to a micro-instruction at every processing routine unit, and in case of branching to other processing routine, a key data of...

PURPOSE:To detect an error of a comparing circuit by adding a small quantity of hardware, by checking a circuit by utilizing an idle time of the comaring circuit, in a processing device containing the comparing circuit. CONSTITUTION:One data of two input data from a write pointer WPR and a read-out pointer RPR is selected by a selecting circuit MPX. When comparing the contents of the pointer WPR a...

PURPOSE:To determine an evaluated threshold value corresponding to difference in the sensitivity simply by combining the results obtained from calibration of a reader/detector employing reflected lights at 2 points different in the reflectivity on the surface of a test paper table and effect and an evaluated threshold valve obtained from the identical calibration of a reader/detector as reference....

The jaw (1) of this binding, intended to hold the front end of the boot, pivots against the action of an elastic system (9, 10) with respect to two vertical support lines (5, 6) arranged on a support piece (12) fastened to the ski (3) and comprising a front support (31) for longitudinal holding of the boot.

SHEET MATERIAL CARRYING AN UNOBTRUSIVE IMAGE AND METHOD FOR ITS PRODUCTION An unobtrusive image is applied to paper or other sheet material by means of a charged droplet printer, for example an ink jet printer. The unobtrusive image applied may perform the function usually associated with a watermark in paper, but in contrast to a watermark, may-be applied to papers during their production on high...

An apparatus for measuring bottom hole conditions such as pressure in the tubing of a well including a locking and sealing sub to lock into and seal against the interior of the tubing, an isolation valve connected in the sub and a measuring instrument connected to the valve for measuring conditions in the tubing. The isolation valve has a bore with an annular seat in the bore and side ports leadin...

A hose connector has a body having a first portion adapted to receive a flexible hydraulic hose and a second portion adatped for connection to a brake actuator. A bore portion of the second body portion is arranged to provide a space large enough to contain at least a major part of any heated brake fluid returning from the actuator upon brake retraction thereby minimizing the amount of heated flui...

A method for the production of micropowders from cellulose ethers or cellulose comprising (a) subjecting a cellulose ether or a cellulose having a fine-fiber, cottony or woolly structure to a consolidation or embrittlement sufficient whereby in one mill pass through a jet mill under standard conditions 98% by weight of the consolidated or embrittled material charged is recovered as a powder of les...

A brake pressure regulating valve inserted inside the pressure chamber of a wheel brake cylinder of a vehicle comprises a differential or stepped piston having its smaller diameter section slidably supported in a bore of a wheel brake cylinder piston and its larger diameter section guided in the bore of a housing for the wheel brake cylinder. The larger diameter section of the stepped piston has a...

A reinforced hardened foam lining may be constructed in a particular zone of a well such as a water well, a geothermal well, or an oil well to plug off or contain salt water intrusion or lost circulation by placing a length of perforated pipe in the desired location; placing foam generating components in a foam generating device in the length of perforated pipe; mixing the resin and catalyst (comp...

Method for the preparation of rigid polyvinyl chloride foams with a density of below 200 kg/m3, in which method rigid polyvinyl chloride which is provided with a melt-flow improver is foamed with a physical blowing agent via an extruder, in which method in a first step, rigid polyvinyl chloride, together with and preferably mixed with 0.1-15 parts by weight per 100 parts by weight of polyvinyl chl...

The invention provides a method of heat-treating a biaxially oriented polyolefin film by constraining the film against shrinkage, heating the constrained film to at least the minimum stress relaxation temperature of the polyolefin, and thereafter cooling the treated film to a temperature below the alpha-relaxation temperature of the polyolefin. The film is preferably heated rapidly to the required...
