摘要： A polyolefin resin composition containing 5 to 150 ppm of an antioxidant and a high-concentration (e.g. 40 to 80% by weight) titanium dioxide pigment is diluted with a polyolefin resin to prepare a medium-concentration (e.g. 20 to 60% by weight) titanium dioxide pigment-containing photographic master batch, then this master batch is further diluted with a polyolefin resin to form a low-concentration (e.g. 5 to 20% by weight) titanium dioxide pigment-containing resin composition, and this resin composition is melt extruded and coated on a support made of paper or a synthetic paper to produce photographic resin coated paper. According to this process, both die lip staining and formation of microgrits are prevented.

摘要： In preparing a polyolefin resin coated paper for photographic use which comprises melt-extruding and coating a polyolefin resin composition containing titanium dioxide onto at least one surface of a paper sheet or a synthetic paper base, a polyolefin resin composition comprising polyolefin resin and titanium dioxide surface-treated with 0.2 to 1.2 wt % (calculated as Al.sub.2 O.sub.3) of hydrous aluminum oxide based on titanium dioxide is employed as the polyolefin resin composition. By the use of such a polyolefin resin composition, problems on operation and quality due to generation of die lip stains could be solved without causing any quality problem such as photodeterioration, or the like.

A photographic support which comprises the above titanium dioxide pigment is also disclosed. Occurrence of die lip stain and microgrit are substantially reduced in the photographic support and a photographic material made thereof exhibits improved image sharpness.

摘要： A pneumatically operated screw driver ensuring a complete return of a piston to its top dead center. The screw driver has a compressed air return chamber for returning the piston to its top dead center by applying a compressed air in the return chamber to the piston. The piston includes a main piston and an auxiliary piston. The main piston is first reaches its bottom dead center, and then the auxiliary piston reaches its bottom dead center whereupon screw driving is terminated. Before the auxiliary piston reaches its bottom dead center, and after the main piston moves past a predetermined position, a compressed air is introduced into the return chamber. After the main piston reaches the bottom dead center, application of the compressed air pressure in the return chamber to the auxiliary piston is prevented.
