Abstract: A user access the control center by a user terminal, and send a request for searching an available locker box in a desired area. The control center has database storing data representing which locker box is available. The control center searches the database for the available locker box which matches the user's request. The control center transmits information of the available locker to the user terminal. As the user reserves the locker, the control center generates one time password (OTP). The control center sends the OTP to the locker controller, and a display unit of the locker displays the OTP. The user inputs the displayed OTP to the user terminal and sends it to the control center. If the OTP is successfully authenticated, the control center sends commands to unlock the locker, thus, the user can use the reserved locker box.

Abstract: A golf ball whose core is covered with a cover, wherein the core is constituted of a rubber composition containing polybutadiene rubber and the cover is constituted of a resin composition composed of ionomer resin and diene rubber. A golf ball cover material composition composed of ionomer resin, diene rubber and non-staining antioxidant. A method of manufacturing a golf ball cover material composition constituted by mixing/kneading ionomer resin and diene rubber.

Abstract: A covering material composition for a golf ball, which comprises an ionomer resin and a diene rubber, the diene rubber being dispersed in the ionomer resin. The covering material composition is produced by mixing the ionomer resin with the diene rubber to disperse the diene rubber in the ionomer resin.
