Title: Fixed pattern noise suppression circuit in amplification type image sensor
Inventor: ARISAWA YASUO
IPC: H04N5/217
Filed: 1990-09-21
Abstract: PURPOSE:To reduce noise which has a considerably low frequency component and random noise by integrating FPN for plural frames with a simple circuit constitution in which a critical pulse is made the shortest and permitting the control signal of a control circuit to set the number of integral frames and an integral interval. CONSTITUTION:When an FPN fetch start signal EN becomes 'H', an FPN input signal inputted from an input terminal 1 is outputted to the output of an adder 6 as it is in one frame period and it is fetched into field memories 7 and 8 for one frame. Then, the output of a monostable multivibrator 9 becomes 'H' and the output of the field memory 8 appears in the output of an initialization circuit 10. Then, the adder 6 and the field memories 7 and 8 integrate and accumulate FPN data for plural frames. When the output signal (b) of the control circuit 11 is operated at that time, not only FPN data for the arbitrary number of the frames are integrated but also the integral interval is freely set so as to accumulate FPN data into the field memories.

Title: Pachinko (japanese pin ball) machine
Inventor: FUKUSHIMA SEIICHIRO
IPC: A63F7/02
Filed: 1988-10-04
Abstract: PURPOSE:To prevent winning mode from being purposely determined by a player by providing a display controlling means for displaying unwinning mode on the basis of a numeral value of unwinning numeral table corresponding to an address specified by a first address renewing means and winning mode on the basis of a numeral value of winning numeral table corresponding to an address specified by a second address renewing means. CONSTITUTION:When a ball enters a specified prize winning port, a mode is determined by a random number generated by a random number generating means. By a display control means, a numeral value of an address specified by a first address renewing means on an unwinning numeral table 32 in the unwinning mode is set to a display controlling numeral value, and a numeral value of an address specified by a second address renewing means on a winning numeral table 33 in the winning mode is set to a display controlling numeral value. Thus, since the display controlling numeral value is determined by a random number table 31 separate from a mode determining random number means, the arrangement of random number table for determining the mode cannot be decoded. Also, displayed numeral value can be freely controlled.

Title: Detecting device for travel distance of running vehicle
Inventor: NAGAI TAKAO
IPC: G01C22/00
Filed: 1993-10-06
Abstract: PURPOSE:To properly detect the current position of a body by calculating travel distance from the number of revolutions of a drive wheel when no slipping of the drive wheel was detected and calculating the travel distance from the number of revolutions and steering angle of the drive wheel when the slipping of the drive wheel was detected. CONSTITUTION:A first operation circuit 12 calculates travel distance from the 1/2 of the sum of the number of revolutions from a drive wheel sped sensor 9 provided at left and right drive wheels and tire diameter, etc. A second operation circuit 13 calculates the travel distance from number of revolutions of a drive wheel rotary sensor 10 provided at the left and right drive wheels and the steering angle from a steering sensor 7. A drive wheel slip detection circuit 15 judges that slipping occurred when the difference between the travel distance calculated from the number of revolutions of the drive wheel and the travel distance equivalent to the drive wheel calculated from the number of revolutions of the drive wheel is equal to or more than a specific value. When there is no slipping, the circuit 12 obtains the travel distance. On the other hand, when there is slipping, the circuit 13 obtains the travel distance, thus preventing the error due to the slipping of the drive wheel and properly detecting the body position by the estimation navigation.
