Abstract: Gaming system based on curvate movement of a jacketed device which may be a smartphone through space on trajectories determined by a user to provide visual, acoustic or physical output based on the user-determined trajectory of the device where the device has a gyroscope sensor for sensing angular acceleration of the device and an accelerometer for determining the magnitude of any acceleration of the device, the gyroscope sensor and the accelerometer cooperate to track the user-determined trajectory of the device, and the jacket has a rotary member for moving the device through space on the trajectory determined by the user.

Abstract: In the invention, an outer case is formed of a transmissive hard synthetic resin, a liquid crystal display board is housed in the outer case in a floating state relative to an inner bottom surface of the outer case, and the liquid crystal display board is surrounded with a transmissive synthetic resin poured into the outer case so that anti-moisture resistance is improved.

Abstract: An organic halide (1) having the general formula: ##STR1## wherein X is a halogen atom, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom, a hydrocarbon group or a halogenated hydrocarbon group, R.sup.1 may be a group having the formula: ##STR2## wherein R is an aliphatic, alicyclic or aromatic radical, and R.sup.3 and R.sup.4 may be a group consisting of -CH.sub.2 OH or its esters; is produced by reacting an organic halide (2) having the formula: ##STR3## wherein X, R.sup.1 and R.sup.2 is the same as above, respectively; with the compound having the formula: ##STR4## wherein R.sup.3 and R.sup.4 is the same as above, respectively, in the presence of a cationic catalyst at the temperature of from -78.degree. C. to 80.degree. C.
