Title: Game machine and recording medium
Inventor: KANAZAWA HIROSHI
IPC: A63F7/02
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To realize a game machine which can prevent lack of paying-out premium media when the power for a game machine restored after the cutoff. SOLUTION: When a sub-CPU refers to a premium number table and a premium number has been stored in the memory (S32: Yes), the number of premium corresponding to the stored premium number is set in a counter (S34) and a premium ball paying-out motor is actuated (S36). After that, when a premium ball paying-out sensor signal is inputted into the sub-CPU (S38), '1' is subtracted from the paying-out number set into the counter (S40) and, when the paying-out number p comes to '0' (S42: Yes), '1' is subtracted from the stored premium number U. That is, because the stored memory number before the subtraction is held since the sub-CPU subtracts '1' from the stored premium number after paying-out the number p of premium balls, premium balls can be paid out based on the stored premium number. Thus lack of premium balls does not occur.

Title: Remote control system
Inventor: FUJISAWA HIDEYUKI
IPC: E02F9/20
Filed: 2000-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a remote control system that controls bulldozers or the like in a stricken area, extends transmission distance, enhances safety and suppresses installation cost. SOLUTION: A repeater 6 relaying data, between three sets of transmitters 2 and receivers 3 adopting the specified low power system, is placed between the them. Each data reception interpret section 10 receives analog signals with frequencies f1, f2, f3 from each transmitter 2 and converts them into digital signals. A data transmission section 11 multiplexes the digital signals and wirelessly transmits the multiplexed signal to a data reception 12 serially. The data reception section 12 receives the digital signal and divides it into three. Each data output section 13 converts the digital signals into analog signals and outputs them with the various frequencies f1, f2, f3 to each receiver 3.  Thus, the transmission distance of a multiple of three or more can be obtained theoretically, and the one-set of the repeater 6 can transmit all the data, regardless of the number of sets of the specified low power wireless units.
