Abstract: In a method for developing attractions in a shooting game system with which players can experience gun fights between the targets and players themselves, the present invention provides a method for developing attractions in a shooting game system with which the shooting game system can be easily installed in a short period anywhere and game quality can be always adjusted in the most suitable state. Namely, the method for developing attractions comprises the steps of producing various types of targets by combining fundamental mechanisms, each of which is used for a unit operation; incorporating unified control equipment and peripherals in the produced target to make them a target unit; embedding the above-described target unit in a target unit case so as to serve also as an indoor partition and posts; arranging the embedded target units in the designated rooms of the attraction hall.

Abstract: An electroplating solution (A), comprises an aqueous solution consisting essentially of lead phenolsulfonate: 1 to 250 g/liter in terms of Pb content; tin phenolsulfonate: 0.1 to 250 g/liter in terms of Sn content; phenolsulfonic acid: 20 to 300 g/liter; polyoxyethylene polyoxypropylene alkylamine: 1 to 50 g/liter; a 1-naphthaldehyde derivative: 0.001 to 1 g/liter; and an aldol sulfanilic acid derivative: 0.1 to 30 g/liter; or an aqueous solution (B) consisting essentially of lead methanesulfonate: 1 to 250 g/liter in terms of Pb content; tin methanesulfonate: 0.1 to 250 g/liter in terms of Sn content; methanesulfonic acid: 20 to 300 g/liter; polyoxyethylene polyoxypropylene alkylamine: 1 to 50 g/liter; and an aldol sulfanilic acid derivative: 0.1 to 30 g/liter.

Abstract: An electrolytic process for producing lead and tin sulfonates which comprises applying a DC voltage to an anode and a plurality of cathodes in an electrolytic cell and thereby dissolving lead or tin in an electrolytic solution. The electrolytic cell is partitioned by cation- and anion-exchange membranes into anode and cathode chambers. The electrolytic solution is a solution of an organic sulfonic acid, and the anode is lead or tin. The process reduces contents of radioisotopes such as uranium and thorium to a level of less than 50 ppb, and therefore the coatings formed by solder plating using the lead and tin salts in accordance with the invention show radioactive .alpha. particle counts of less than 0.1 CPH/cm.sup.2.

Abstract: An image processing method in which an image signal of frames of pixel data is divided to provide a plurality of blocks and the step of dividing the image signal into blocks is comprised of the steps of dividing one frame of the image signal into at least first and second fields, dividing the first and second fields into at least first and second groups alternately for each pixel forming a block from these four groups, and arranging the positions of the divided groups such that boundaries of the divided blocks are not overlapped between the groups.
