Title: Game machine
Inventor: YAMAGUCHI MITSUO
IPC: A63F7/02
Filed: 1989-06-07
Abstract: PURPOSE:To make a game impossible to be continued by a method wherein a driving voltage is applied on a liquid crystal panel according to a detected signal when and illicit prize action is detected by a detector. CONSTITUTION:When a player radiates magnetic waves by an oscillator, a wave detecting circuit 19 detects the magnetic waves having a specified frequency, and outputs a signal having a voltage corresponding to the electric field strength of the magnetic waves detected by the wave detecting circuit 19 to a comparing circuit 21. When the electric field is strong enough to cause a game ball detector to make an error in action, a signal is output to a liquid crystal driving circuit 25 via a timer circuit 23. The liquid crystal driving circuit 25 applies a driving voltage of a specified voltage to electro-conductive transparent films 9c and 9d. When the driving voltage is applied to the electro- conductive transparent films 9c and 9d, the moleculars of the liquid crystal are irregularly arranged, not allowing light to pass through. As a result, the player can not visually confirm prize hole guide nails and accessories, that makes the game impossible to be continued.

Title: Current output circuit
Inventor: YUASA TACHIO
IPC: H03F3/30
Filed: 1991-06-18
Abstract: PURPOSE:To ensure a potential amplitude at an output terminal by applying voltage feedback to an input side of a transistor(TR) of an output stage from its output side and compensating dispersion in the ON resistance via the conduction of the TR at the output stage. CONSTITUTION:A voltage feedback is applied to bases of output stage TRs 31, 32 from collectors of the TRs 31, 32 of the output stage. As a result, since the potential of the bases of the output stage TRs 31, 32 is close to the collector potential, the conduction state of the TRs 31, 32 is progressed more in comparison without voltage feedback application. Since a current flowing to the inside is increased, the dispersion in the ON resistance is reduced. As a result, fluctuation of a bias potential at an output terminal Z is suppressed small and the potential amplitude is increased, then a proper output current is obtained when a signal input is given to an input terminal X.

Title: Phase lock detection circuit
Inventor: YAMAKAWA KUNIO
IPC: H04L7/033
Filed: 1988-06-15
Abstract: PURPOSE:To ensure the detection of a phase lock state by deciding the locking state depending on a level of a control voltage of a voltage controlled oscillator. CONSTITUTION:When a phase locked loop circuit is in the locking state, an output of a 1st level decider 7 goes to a high level and the output of a 2nd level decider goes also to a high level. Then a switch 9 is thrown to the position of a terminal (a) and an output high level of the said 1st level decider 7 becomes a phase locking detection signal. When the voltage controlled oscillator 5 is in the sweep state, the output of the 2nd level decider 8 repeats high/low levels. A synchronization detection signal goes to a low level. When the output frequency of the voltage controlled oscillator 5 is deflected out toward higher (lower) direction than the center frequency, the control voltage of the voltage controlled oscillator 5 is a positive (negative) power voltage. Thus, the output of the 1st level discriminator 7 goes to a low(high) level and the output of the 2nd level discriminator 8 goes to a high (low) level and the phase synchronizing detection signal goes to a low level.

Title: Screen
Inventor: OGINO MASANORI
IPC: H04N5/74
Filed: 1988-06-15
Abstract: PURPOSE:To obtain a back projecting screen having a wide orientation angle and less color shift through the use of plural CRTs arranged horizontally by using an elliptic one as a lenticular lens for horizontal diffusion on an incident side and taking advantage of coma aberration generated by said lens. CONSTITUTION:The profile of the lenticular lens 22 on the incident side is defined as an elliptic shape whose eccentricity (e) equal to an inverse of the refraction factor (n) of a medium. Incident beams are in parallel with the major axis of an ellipse, that is, an optical axis, and they are converged on a focus (e) without wave surface aberration after they are refracted on the face of the lens. Therefore a horizontal orientation characteristic is considerably improved. By selecting the profile of a lenticular lens on an outgoing side so as to reduce color shift by taking advantage of coma aberration, a wider orientation angle and less color shift can be realized.
