Title: Video signal reproducing circuit
Inventor: IIZUKA HIROSHI
IPC: H04N9/84
Filed: 1994-07-11
Abstract: PURPOSE:To reduce the number of frequency conversion circuits and BPFs by restoring the phase of a low-band conversion color signal before frequency conversion to directly apply the oscillation output signal of a VCO to a frequency conversion circuit. CONSTITUTION:An input color signal is extracted by an LPF 2 and is applied to an ACC circuit 3 and has the level adjusted and is applied to a phase restoring circuit 50. The phase rotation for recording is restored in the circuit 50. That is, phases of all low-band conversion color signals are restored to the same phase in the circuit 50; and therefore, the present signal and the signal of IH before are merely added by a means 51B to eliminate the noise component, and the signal is outputted in the double level. Consequently, a comb line filter 51 consists of only a delay circuit 51A and an addition circuit 51B. The output signal of the filter 51 is applied to a frequency conversion circuit 53, but its phase restoration is unnecessary, and it is sufficient if this output signal is subjected to frequency conversion by 4.21MHz single frequency, and the output signal of a VCO 56 which oscillates 4.21MHz can be directly applied to the circuit 53, and the number of frequency conversion circuits and BPFs is reduced.

IPC: H04B7/08
Filed: 1992-06-18
Abstract: PURPOSE:To improve the reception performance of a multiplex signal by revising a changeover condition of an antenna or a reception system depending whether the mode is at main signal reception or a multiplex signal reception. CONSTITUTION:An output of an intermediate frequency amplifier circuit 4 is given to an electric field fluctuation detection circuit 11 and an output of the circuit 11 is given to an antenna changeover condition detection circuit 12 in the stereo broadcast reception state. When an electric field fluctuation of a stereo FM broadcast during reception by, e.g. an antenna 1a exceeds a preset level, an output of the circuit 12 activates a changeover control circuit 13, and the antenna changeover circuit 2 selects the antenna 1b in place of the antenna 1a. On the other hand, during the reception of a multiplex signal, a subcarrier extracted by a subcarrier extract circuit 14 is given to the circuit 12, which discriminates the state of the subcarrier requiring antenna changeover, then the circuit 12 activates the circuit 13 to select other antenna.

Title: Frequency converter for satellite broadcast receiver
Inventor: SUZUKI HIDENORI
IPC: H04B1/18
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit converter (2nd converter) used for receiving a satellite broadcast, employing both a frequency modulation system and a phase modulation system. SOLUTION: An input signal Si is obtained by frequency conversion by a frequency converter (1st converter) provided with a satellite. Required processings, such as amplification and intermediate frequency conversion, are applied to the input signal. The intermediate frequency signal of a station, selected by a channel selection section 3 is subject to amplification processing or the like, and the result is given to a changeover section 9. The changeover section 9 is thrown to the position of an FM demodulation section 12 or a QPSK demodulation section 13 by a changeover control section 11, based on station designation data in channel selection. The changeover control section 11 sets the changeover section 9 to a required position, based on memory data in cross reference between station designation data which are stored in advance in a memory section 10 and changeover setting setting position data and on station designation data from the channel selection section 3. Thus, the signal of the FM modulation system is demodulated by the FM demodulation section 12, and the signal of the QPSK modulation system is demodulated by the QPSK demodulation section 13.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To easily get a timing for depressing stop buttons by permitting a next reel to start rotation when the prescribed pattern of the reel which precedently started rotation coincides with the prescribed pattern of the next reel which is to succeedingly start rotation, in the case of starting the rotations of the reels in a slot machine. SOLUTION: When a game player throws a metal into a throw-in port, starts a game, operates a start lever 105 and permits the reels 101-103 to start the rotations, the left reel 101 starts rotating at first and the patterns are moved downward. When the specified pattern (for example, 7) of the left reel 101 reaches the specified pattern of the middle reel 102, the both reels 101 and 102 are rotated together. Then, when the specified patterns reach that of the right reel 103, the right reel 103 starts rotating. In this state, the player successively executes operations for depressing the stop buttons 121-123 and stops the respective reels so that the medals are discharged in accordance with the patterns which are coincident in an effective line in a stop state.

Title: Drive control device for solenoid valve
Inventor: HANIYUDA NOBUYOSHI
IPC: F16K31/06
Filed: 1984-07-30
Abstract: PURPOSE:To reduce a consumed current for a solenoid by connecting capacitors with detecting resistances in parallel and applying a standard value in a comparison section to the holding current value of the solenoid. CONSTITUTION:When a drive control unit has been started, an accumulated charge in a capacitor C is saturated, and the terminal voltage of a detecting resistance R8 increases. In other words, a feedback gain increases, and then a comparison section 2 begins a feedback control. In this case, since the standard value in the comparison section 2 has been set to serve as the holding current value of a solenoid 3, a driving current passing through the solenoid 3 is controlled so that the holding current may be kept constant. The feedback control can therefore control the driving current to the holding current to prevent a useless electric power loss.
