PURPOSE:To make the facing repair of a disc rotor possible in the state of a loaded car by providing a fixing mechanism for fixing a cylinder body to a torque member when a brake pad has been exchanged for a grinding pad in a disc brake whose cylinder body slides in the direction of an axle. CONSTITUTION:In the case where a facing work is carried out on a disc rotor 2, a tire is removed, and a bra...

PURPOSE:To stop light transmission effectively without spoiling picture quality and to improve the printing performance of a mask material for image formation by providing a light reflecting layer to the light nontransmissive layer of the thermal transfer sheet when the mask material for image formation is formed by using a thermal transfer system. CONSTITUTION:The thermal transfer sheet 1 compose...

PURPOSE:To obtain higher image quality and higher contrast and to improve the printability on the image forming mask material by using a thermal transfer system, by which a light non-transmittable layer of the original plate of the image forming mask material is surely peeled and transferred to a receiving sheet side. CONSTITUTION:The layer 3 side of the original plate 1 of the image forming mask ...

An elasticized non-woven fiber material is made by combining one or more textile fibers with one or more elasticizeable fibers and bonding the combined fibers together. The resultant web of bonded non-woven fibers is then heattreated to heat-shrink the elasticizeable fiber and recover its elasticity thereby shrinking the fibers and the web of material. An elasticized non-woven fabric made by the d...

A process for treating a waste water containing uranium and fluorine comprises a neutralizing precipitation step wherein slaked lime is added to the waste water containing uranium and fluorine and precipitate thus formed is separated and removed, and an adsorption step wherein supernatant from the neutralizing precipitation step is contacted with a chelating resin which can selectively adsorb fluo...

Digital signals, such as digitized television signals, are subjected to a source coding step in which a class of "most important" data elements represents a proportionately greater amount of the information to be communicated than the rest of the data elements. This is followed by a constellation mapping step which is carried out in such a way that those data elements have a lower probability of b...
