A planar antenna fitted with a reflector of small shape and small depth. A reflector 21 of planar shape is provided at the rear face of a radiator 20 of planar shape made of a triangular loop element. The side sections 21b on both sides of the reflector 21 are bent towards the radiator 20 and the separation .alpha.2 between the leading edges of the side sections 21b and the side edges of the radiator 20 is thereby reduced. In this way, an excellent electrical characteristic of the planar antenna 2 fitted with a reflector and can be achieved by reducing the separation D2 of the radiator 20 and reflector 21.

A novel transition metal complex, preferably a ruthenium-phosphine complex or rhodium-phosphine complex, which is effectively usable in various asymmetric syntheses and, in particular, is more effectively usable in the asymmetric hydrogenation of various ketones; and a novel process for producing an optically active alcohol with the complex. The novel transition metal complex includes a ligand obtained by introducing a diarylphosphino group into each of the 2- and 2′-positions of diphenyl ether, benzophenone, benzhydrol, or the like. It preferably further includes an optically active 1,2-diphenylethylenediamine coordinated thereto. The complex preferably is a novel diphosphine-ruthenium-optically active diamine complex or diphosphine-rhodium-optically active diamine complex. The process comprises using the complex as an asymmetric hydrogenation catalyst to conduct the asymmetric hydrogenation of a ketone compound to thereby obtain an optically active alcohol in a high optical purity and a high yield.

This method includes the step of reacting a vinyl ether with a halogenated acetaldehyde in the presence of an optically active binaphthol-titanium complex.

A phase shift mask, e.g. a halftone phase shift mask, which need not to form an ultra-fine pattern and is capable of suppressing during exposure the occurrence of a sub-peak of light intensity, which has an adverse effect on the image formation, and which has a light-blocking pattern with a reduced transmittance at a region outside a device pattern area which corresponds to a region subjected to multiple exposure during transfer effected by using the mask. The halftone phase shift mask has on a transparent substrate (101) a halftone phase shift film (102) comprising a single layer or a plurality of layers. The composition of the halftone phase shift film (102) is changed in a region (107) outside a device pattern area on the transparent substrate (101) which corresponds to a multiple-exposure region by a method wherein the region (107) is irradiated with an electromagnetic wave, a particle beam, heat rays, etc., or a method wherein after a region in which the composition is not desired to change has been masked, the whole blank is exposed to an active atmosphere, thereby reducing the transmittance for exposure light at the region (107).
