A pneumatic radial tire comprising a toroidal carcass layer having a number of radially extending cords buried therein, a belt layer arranged on a radially outer side of the carcass layer and containing a number of nonstretchable cords inclined to an equatorial plane of the tire, and a reinforcing layer arranged between the carcass layer and the belt layer and containing a number of reinforcing elements. The reinforcing elements extend in parallel to the tire equatorial plane as a whole, and are waved at a substantially equal wavelength. The phase of a plurality of the reinforcing elements among all the reinforcing elements buried in the reinforcing layer is different from that of the remaining reinforcing element or elements.

The use of isoquinoline derivatives for the treatment of glaucoma or ocular hypertension. The isoquinoline derivatives are of formula I ##STR1## wherein R.sub.1 is a hydrogen atom or a C.sub.1 -C.sub.6 alkyl group and R.sub.2 is a C.sub.1 -C.sub.6 alkyl group. The stability of the isoquinoline derivatives when used in the form of a solution is improved by incorporating therein compounds having a phenolic hydroxyl group and/or glycols serving as a stabilizer.

摘要:
A laser beam machining apparatus, in which the focal position of the laser beam is changed, for instance, from the upper surface of a workpiece to the lower surface during laser beam machining, the optical axis of the laser beam passed through the optical system is not affected, and the gap between the nozzle and the workpiece is maintained optimum at all times. The laser beam machining apparatus comprises an optical system for concentrating a laser beam, a holder for holding the optical system, first drive means for moving the holder along the optical axis of the laser beam, a nozzle slidably engaged with the holder, jetting a machining gas or the like, and second drive means for moving the nozzle.

The invention provides an apparatus for processing a sheet-shaped silver halide photographic light sensitive material having a hydrophilic colloidal layer on a substrate without dipping it in a processing solution in a tank. In the apparatus, there are provided a conveying device having a pair of conveying belts disposed to face each other with a gap, wherein the gap is made so that the pair of conveying belts hold the developing solution therebetween. Accordingly, the conveying device conveys the sheet-shaped material with the developing solution between the pair of conveying belts.
