Patent JP-H02308677-A (JP)
Title: Differential circuit
Inventor: FUJII TOSHIKAZU
IPC: H03F3/45
Filed: 1989-05-23
Abstract: PURPOSE:To decrease number of pins and to make the circuit suitable for circuit integration by connecting a resistor to a base of a transistor(TR) toward the output side in 1st and 2nd TRs. CONSTITUTION:When a common contact 27a of a changeover switch 27 connects to a 1st fixed contact 27b, a base of a TR Q2 connects to ground through a capacitor C1 in terms of AC and the pin 23 is open in terms of DC. Thus, a TR Q3 is cut off and an output signal from a signal line 2 1 is applied as it is to a differential amplifier circuit comprising TRs Q1, Q2. That is, the connection of the capacitor C1 to the pin 23 acts like eliminating the output DC component. On the other hand, when a common contact 27a of the changeover switch 27 connects to a 2nd fixed contact 27c, a current flows to resistors R2, R3 to turn on the TR Q3 and an output signal from the signal line 21 is extracted from the pin 23 and monitored.

Patent JP-S6021612-A (JP)
Title: Graphic equalizer
Inventor: SUZUKI RIYOUJI
IPC: H03G5/16
Filed: 1983-07-15
Abstract: PURPOSE:To suppress noise superimposed on an input signal by controlling a level of a signal of each band with a coefficient based on the S/N of each band. CONSTITUTION:The input signal is divided into n-bands by band-pass filter groups 41-4n, a level of each band is adjusted depending on a control signal from a demultiplexer 150 by means of programmable level adjusting devices 51- 5n and signals of each band whose level is adjusted are added by an adder 60 and outputted. The input signal whose band is divided is fed to rectifier smoothing device groups 80-8n, converted at an A/D converter 100 and stored in an RAM 130 via a microcomputer 120. The computer 120 obtains the noise suppressing coefficient based on the level information of each band stored in the RAM 130 so as to estimate the level eliminated for noise. Since the level at a band having a low S/N is lowered largely much more than that at a band having a high S/N, the noise superimposed on the input signal is suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a game machine and a playing method which allows a pattern mating game to sustain a persistency so as to cause a play to sustain his/her expectation for a prize, and a thrill and an excitation. SOLUTION: A ball enters a specific winning hole 12, a random lottery which possibly produces a prize and a semi-prize. If the result of the lottery gives the semi-prize, a reach pattern which differs from a prize pattern by only a part is displayed on a variable display means 20. Further, when it is the semi- prize, a pattern change limiting means 70 limits a change of a pattern part of the already displayed reach pattern which is common with the prize pattern in a pattern mating game which is carried out when a ball enters a winning hole subsequent to the next time. For example, when a semi-prize pattern '767' are displayed while a prize pattern gives '777', only the center figure corresponding to '6' is changed in a pattern mating game which is carried out subsequent to the next time.
