The interpolation filter circuit 28 detects the level difference between the signals A and B and the level difference between the signals B and C and the signals A, C are mixed at a prescribed ratio in response to the result of detection to generate and output an adaptive interpolation signal. The adaptive interpolation signal is given to a 1st adder circuit 27. Then the adaptive interpolation signal subjected to noise reduction and vertical contour compensation is outputted from the adder circuit 27.

Title: Signal mis-detection protecting system for japanese pinball game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1994-06-27
Abstract: PURPOSE:To prevent a pinball game (pachinko) machine from mis-operation even if an incorrect output signal is received due to a power supply voltage drop. CONSTITUTION:For example, when a power supply does not maintain its specified voltage for some reasons such as an instantaneous service interruption, a voltage monitor means 20 outputs a warning signal. During this warning signal being received, an input means 30 ignores signals even if receiving those outputted from a signal output means 10. In this way, since an outputted working signal is detected when the power supply voltage drops below a specified value, a pinball game machine is prevented from mis-operation due to mis- outputted signals.

IPC: C23F13/00
Filed: 1984-07-12
Abstract: PURPOSE:To prevent the electric corrosion of an artificial satellite by fixing terminals on different metallic materials forming the structure of the satellite and by applying DC voltage between the terminals from a DC power source so as to eliminate electromotive force produced between the different metallic materials. CONSTITUTION:The structure of an artificial satellite is composed of structural parts 2 made of a metallic material A and a structural part 3 made of a metallic material B.

Terminals 4 are fixed on the parts 2, a terminal 5 is fixed on the part 3, and the terminals 4, 5 are connected to a DC power source 6. The ionization of the materials A, B is prevented by applying DC voltage between the terminals 4, 5 from the power source 6. Thus, the electric corrosion of the satellite is prevented.

Abstract: PROBLEM TO BE SOLVED: To improve sensitivity by coaxially coupling an input axis with an output axis, facing them so that protrusions and recesses formed on both cylindrical end faces of a magnetic body which rotates integrally with the respective axes interdigitate, and measuring a change in magnetic resistance at opposite parts. SOLUTION: A yoke 6 of a magnetic body having a U-shaped cross section is provided inside a housing 9. The yoke 6 has an axial direction length across cylinders 4, 5 and its axial direction center is placed so that a protrusion 4a and a recess 5a are approximately aligned with each other at opposite positions. A magnetic coupling detection coil 7 is provided in the yoke 6, and the coil 7 is connected to an oscillator whereby the yoke 6 constitutes a magnetic circuit together with the cylinders. When a steering ring is steered, an input axis 2 is rotated, and an output axis 3 side is difficult to rotate since it is coupled to a steering mechanism. A gap length between the protrusion 4a of the cylinder 4 and the recess 5 of the cylinder 5 varies. A change in inductance due to the change in this magnetic gap cross-sectional area is detected by the coil 7.

Title: Digital displacement sensor
Inventor: KAJIWARA YASUNARI
IPC: G01B21/00
Filed: 1988-06-13
Abstract: PURPOSE:To simplify the signal conversion to a microcomputer so that it is scarcely influenced by noise by counting the displacement quantity which is converted to a digital signal in accordance with a phase by an up-down counter part. CONSTITUTION:Two sensors 11, 12 output pulse signals whose phases are different by 90 degrees, respectively. An up-down counter part 13 counts its pulse in accordance with phases of output signals of two sensors 11, 12. For instance, in case of the displacement in the clockwise direction, an up-count is executed, and in case of the displacement in the counterclockwise direction, a down-count is executed. In this regard, this up-down counter part 13 is corrected, whenever an object to be measured always passes through a reference position. Such a digital displacement sensor outputs a trigger signal as a command signal, when a controller requires data, and can read the data with a good timing.

Abstract: PURPOSE:To facilitate the generation of gate signals of a teletext device by comparing the polarities of plural lines of the output of a 1st decoding circuit with those of plural lines of a 2nd decoding circuit. CONSTITUTION:Clear signals are supplied to 1st-12th D latch circuits 11-22 via a clear input terminal 23. The outputs (c)-(f) of a counter 2 are supplied to the input of the 2nd decoding circuit 24. The output of a 1st NOR circuit 25 produces '1'; while the outputs of 2nd-12th NOR circuits 26-36 all produce '0'. As a result, the gate signal (g) of '1' is produced by 1st-5th OR circuits 37-41 and an AND circuit 42. While the output of the counter 2 is equal to '0010' when a horizontal synchronizing pulse (a) is equal to 12H. Thus the P2 output of the circuit 24 is '0' and other outputs are all '1'. Then the output of a 3rd NOR circuit 27 is equal to '1' and the signal (g) of '1' is generated.
