Abstract: A deductive numerical game played by plural (N) players, one of whom is a dealer, includes N sets of first game pieces, each set including a like plurality (M) of game pieces respectively bearing indicia representing consecutive numbers. A second set of game pieces respectively bear indicia representing different cumulative totals equal to the sum of the numbers displayed on J (J is less than M) first game pieces to be selected from the first game piece set of the dealer. The J first game piece set of the dealer defines a match set hidden by the dealer from each other player's view. The dealer selects and displays a second set game piece to inform each player of the cumulative total equal to the sum of hidden indicia displayed within the match set. Each player in turn selects J first game pieces with indicia having a total corresponding to the dealer's second set game pieces cumulative value.

Abstract: A warning device for a vehicle includes a steering angle detector (10) producing steering angle pulses (S.sub.2, S.sub.3) indicative of the steering angle and the steering direction whenever the variation of the steering angular position exceeds a predetermined angle. A dozing detecting circuit (16) distinguishes that the driver is in a normal condition when excessively frequent steering operations in one direction are performed or when the interval of the steering angle pulse is longer than a predetermined value, and produces a warning signal when steering operations, each of which does not exceed the predetermined angle in one direction, are repeated at a rate greater than a predetermined frequency. A warning device (26) produces a visible or audible warning in response to the warning signal, whereby the warning device can accurately detect dozing of the driver and produce a warning to make the driver wake up.

Abstract: There are provided at least two liquid level detectors in a liquid tank, such as an automobile fuel tank. The detectors are connected so as to obtain the sum of the output signals of the detectors. The positions of the detectors in the tank are determined on the basis of a predetermined reference point. If the reference point lies on a liquid surface formed by a certain amount of a liquid contained in the tank when the tank is horizontal, then the liquid level at the reference point is constant when the tank is inclined so that a horizontal axis of the tank slopes down in one direction at a predetermined angle with the horizontal and when the tank is inclined so that the horizontal axis slopes down in the opposite direction at the same angle with the horizontal. One of the detectors is disposed in a first vertical plane, and the other in a second vertical plane.

Abstract: A backup control apparatus comprises a main control system (1) and a backup control system (2), coupled in parallel, and correcting circuits (61 to 64). If and when the main control system is in an abnormal state, the abnormal state of the main control system is determined by a switch control portion (3). A drive portion (5) coupled to the output of the main control system is switched by a switch portion (4) in response to the determined output to be coupled to the output of the backup control system. A tracking signal obtained from proportional integrating elements (17, 19) included in the main control system abruptly fluctuates as a function of the abnormal state of the main control system. The fluctuation of the tracking signal is mitigated by the correcting circuit including a dead time component or a first order lag component, whereupon the same is applied to proportional integrating elements (27, 29) included in the backup control system.

Abstract: A multichannel digital magnetic recording apparatus comprises a plurality (N) of modulating circuits (41 to 4N) and timing circuits (51 to 5N). Digital signals (Z1 to ZN) undergo modulation in the modulating circuits in accordance with a modulation system of a detection window Tw. The modulated signals (A1 to AN) are converted into pulse current trains by the timing circuits and then delayed such that the respective pulse currents do not occur simultaneously. Accordingly, a power capacity required of a voltage source for writing the signals by means of thin film magnetic heads (71 to 7N) is considerably decreased.

Abstract: A frequency determining apparatus discriminates between two different frame frequencies in television signals. A binary counter (4) makes a 1/64 frequency division of a horizontal synchronizing signal outputted from a horizontal synchronizing signal producing circuit (2), and further makes a 1/2 frequency division of the frequency divided output therefrom. A NAND gate (5) is responsive to the 1/64 frequency divided output and the 1/2 frequency divided output from the binary counter to detect the normal frame signal at 60 Hz, thereby to set a D-type flip-flop (8). Another NAND gate (51) is responsive to the signal obtained by inverting the 1/64 frequency divided output from the binary counter (4) and the 1/2 frequency divided signal to detect the normal frame signal at 50 Hz, thereby to set another D-type flip-flop (81). An R-S flip-flop (13) is set by the respective outputs from these D-type flip-flops whereby a desired determined signal is outputted.

Abstract: A heat dissipating member including a heat sink is placed on a module base board with flip-chips mounted thereon, with metallic plates and first adhesive materials of a good thermal conductivity interposed between the heat dissipating member and the flip-chips in a close contact relation and with a second adhesive material interposed between the heat dissipating member and the base board, wherein the first adhesive material is selected to have a melting point lower than that of the second adhesive material, and then such an assembly is heated so that both the first and second adhesive materials are melted and the metallic plates are mounted onto the flip-chips and the heat dissipating member is mounted onto the base board. A gap is formed between the metallic plates and the heat dissipating member as a result of earlier solidification of the second adhesive material than that of the first adhesive material so as to be precisely controlled such that a heat transferring effect therebetween may not be degraded.
