Abstract: PROBLEM TO BE SOLVED: To provide a speaker device for sound field adjustment and a speaker mounting device, which can adjust the position of a rear speaker, in particular, to a proper position in a surround speaker system.
SOLUTION: The speaker device for sound field adjustment and the speaker mounting device capable of being listened at an optimal sound field are obtained, by laying a guide rail member 20 (20L, 20R, 20B, 20 B
1 , 20 B
2 ) at an indoor ceiling 22 or an indoor wall 21 and placing the speaker device 30 (14, 15, 16, 17, 18, 19) slidable on the guide rail 20 at a predetermined position, and fixing the device to the predetermined position on the guide rail structure 20 by locking.

Abstract: PROBLEM TO BE SOLVED: To provide a reproduction device which prevents deterioration in sound quality of a reproduced audio signal by adjusting timing of reading by a data reading part and a reproduced signal processing part. SOLUTION: The reproduction device is provided with a decoder 5 for providing signal processing to a digital signal reproduced from a disk 1, a reference clock generating part 11 for generating a CLK 1 at reading of the digital signal provided with the signal processing, a memory 6 for temporarily storing the read digital signal, a D/A converter 7 for converting the digital signal read from the memory 6 into an analog signal, and a clock generator 14 for oscillating the CLK 2 in the D/A converter 7, and since the CLK 1 is made slightly larger than the CLK 2, the mutual peak points in time are deviated slightly and the electrical noise due to each peak will not be conspicuous, the signal reproduced is prevented from deterioration.

Abstract: PURPOSE:To suppress excessive erasing due to self convergence and to reduce current consumption at the time of writing. CONSTITUTION:When a gate voltage VG and a drain voltage VD having proper values corresponding to processing at each step are suitably generated from a constant voltage circuit 4 for VG and a constant voltage circuit 5 for VD and the erase by means of F-N tunneling is performed, a high voltage is applied on a control gate CG and a drain D is made to be 0V. A high voltage is also applied on a gate CG, a floating gate FG is made to be high potential, the oxidized film of the tunnel part of the gate FG is made to generate high electric field, a tunneling current FN from the gate FG to the drain D is caused to flow so as to execute erasing. Namely, assuming that coupling capacity between gates CG and FG is CC, coupling capacity between the gate FG and the drain D is CD and a threshold voltage is Vth, a voltage Vp depending upon the process is made to be the voltage shown by the equation.

Abstract: PROBLEM TO BE SOLVED: To restrict the deterioration of quality of reproduced data because of magnetization during the reproduction by setting a magnetic field application means for applying a magnetic field to an optical disk in a disk apparatus which can reproduce information recorded on the optical disk. SOLUTION: A coil 22 is set on the side of a record face of an optical disk 1, and arranged adjacently to be opposite to the optical disk 1 and separated from an optical pickup 3 via a rotation center of the optical disk 1. When a switch 24 is turned on, an a.c. is supplied to the coil 22, whereby an alternating field is generated from the coil 22. The alternating field penetrates the optical disk 1. Since the intense alternating field generated from the coil 22 penetrates the optical disk 1 at an area of the optical disk 1 where the coil 22 is set, a degree of magnetization greatly changes in a positive-negative direction, and the optical disk is magnetized to a magnetic saturation point or higher and an effect by a fringing field from the optical pickup 3 or the like can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To suitably prevent the generation of the distortion of a sound caused by the control of a switching element while suppressing a power loss and reducing a calorific value, in a switching power supply system for an audio digital amplifier.
SOLUTION: The switching power supply system 10 comprises a power accumulation part 16 that accumulates power generated by a switching power supply 14 and feeds it to the audio digital amplifier 12. A switching control circuit 38 of the switching power supply keeps a power generation level of the switching power supply at a prescribed power generation level when a power accumulation level of the power accumulation part is not lower than a prescribed power accumulation level, and when the power accumulation level of the power accumulation part is lower than the prescribed power accumulation level, the switching control circuit raises the power generation level of the switching power supply to a level higher than the prescribed power generation level.

Abstract: PROBLEM TO BE SOLVED: To provide a setting state display method whereby setting states of all setting items of an AV apparatus such as a DVD player and an AV amplifier can be confirmed by simple operations.
SOLUTION: An apparatus main body of the AV apparatus or a remote controller is provided with a global display key (all setup check key). When this key is depressed, a CPU of the apparatus main boy totally and hierarchically displays the setting states of all the setting items of the AV apparatus on a screen of a display apparatus connected to the AV apparatus in a form of a global display menu 7 and displays a cursor 8 on the global display menu 7. A user moves the cursor 8 on the global display menu 7 and depresses an enter key to revise the settings of the setting item to be revised without the need for displaying all the hierarchical menu images.
