摘要:
Flame retardant heat insulating material and a method for preparing the same characterized in that a ground mixture of cellulose fibers with cellulose flakes or particles is chemically or physically bonded with condensed ammonium phosphate to form a fiberfil.
摘要:
An anti-blooming flame retarder consisting essentially of a water-soluble flame retardant agent and a water-soluble polymer, which is particularly suited for use in treating improved woods such as fiber-boards and plywoods. The improved woods are treated with the anti-blooming flame retarder and heat-treated.
摘要:
A controller for controlling a plurality of collided object-protecting apparatuses for absorbing impact at the time when a collided object collides with a hood, the controller including at least a predicting mechanism for predicting a vehicle collision and detecting mechanism for detecting a vehicle collision, and a control mechanism for controlling operations of the plurality of the collided object-protecting apparatuses, respectively, at different timings.
摘要:
In a synchronization judging circuit, a measuring portion measures a signal to interference power ratio of a received signal at each frame. An averaging portion calculates a moving average of a series of signal to interference power ratios for a predetermined number of frames to produce a mean value at each frame. A counter counts a number of consecutive frames each of which the mean value meets a predetermined threshold requirement. The counter further compares a counted value with a predetermined threshold value to decide whether to perform a transmission control operation or not.
摘要:
An internal combustion engine with single overhead camshaft which comprises a cylinder block having at least one cylinder bore and accommodating therein a piston, and a cylinder head having a bottom wall flattened at a surface area confronting a combustion chamber, and firmly mounted on the cylinder block. The bottom wall has a pair of intake ports and a pair of exhaust ports which are selectively closed and opened by separate intake valves, one for each intake port, and separate exhaust valves, one for each exhaust port. The intake and exhaust valves are supported by the cylinder head for movement in a direction generally perpendicular to the planar surface of the bottom wall. A single overhead camshaft extends above and between the intake valves and the exhaust valves transversely of the longitudinal axis of the cylinder bore, and has first and second cam means. The piston has a flat top end face confronting, and generally in parallel relationship with, the planar surface of the bottom wall of the cylinder head and has a cavity defined in said flat top end face. The cylinder head also has a socket defined therein so as to extend completely through the thickness of the bottom wall for the support of either an ignition plug or a fuel injector nozzle.
摘要:
A water-soluble flame retarder comprising a condensed ammonium phosphate having an average degree of condensation of not more than 60 and a mixture of urea compounds produced from urea in the presence of a condensed ammonium phosphate, the mixture containing biuret and triuret. The flame retarder is advantageously prepared by reacting urea and phosphoric acid in a particular manner to by-produce particular amounts of biuret and triuret.
