Abstract: In a nonvolatile semiconductor memory device, the increase of the capacity of a nonvolatile semiconductor memory inevitably causes the power supply circuits including the charge pump circuits at the periphery to increase. In view of the above situation, the object of the present invention is to provide a technology of allowing a nonvolatile semiconductor memory to increase the capacity without increasing the power supply circuits which are the peripheral circuits of the nonvolatile semiconductor memory.

Abstract: Side plates, constituting side surfaces of a speaker cabinet, each comprise a base member having a plurality of grooves formed in its outer surface (obverse surface) region at predetermined intervals, and a decorative plate adhesively bonded to the outer surface of the base member, in a laminated fashion, so as to cover the grooves. The laminated base member and decorative plate are pressed and curved, via upper and lower molds, so as to provide a smooth, convexlycurved outer surface. The grooves are adhesively bonded along their opening edges to the inner surface of the decorative plate, so that the opening edges of each of the grooves will not move toward or away from each other when external force is applied to the side plate.

Abstract: In an optical pickup device, reliability of a holding structure for an optical component (a half mirror) with respect to a pair of mounting frames is intended to be enhanced. A half mirror (5) is arranged so as to bridge a first frame (11) and a second frame (12). A side face (5C) positioned in a part in which one side of an emitting face (5B) (a mounting face) of this half mirror 5 and the first frame (11) are overlapped is fixed to the first frame (11) by adhesives (13A) of two contact points. On the other hand, a side face (5) positioned in a part in which the other side of the emitting face (5B) and the second frame (12) are overlapped is fixed to the second frame (12) by an adhesive (13B) of one contact point. In this manner, even in case where the frames (11, 12) have been displaced due to thermal expansion, the adhesives (13A, 13B) will not be flaked off, and bonding strength of the half mirror will be enhanced.

Abstract: Power amplifies are provided to correspond with a plurality of speaker units constituting a speaker array. Driving signals from the power amplifies are supplied to one terminals of the speaker units, and other terminals are connected a common line. Inverters are provided at preceding stages of the power amplifies such that the driving signals supplied to the speaker units being arranged adjacently have an opposite phase respectively. Since a correlation between the driving signals of the adjacent speaker units is high, a current flowing through the common line can be very reduced. An LED display panel can be driven by the similar method.

Abstract: A digital signal receiving apparatus which can automatically determine the transmission format of a digital audio signal based on AES3, and then simplify the operations, avoid wrong operations at times of switching, and prevent errors in the transmission format due to wrong operations. In this apparatus, a channel status FS detection section 109 detects the sampling frequency of an input digital audio signal based on AES3, a transmission rate detection section 111 detects the transmission rate of the input digital audio signal based on AES3. A control section 113 determines the transmission format of the input digital audio signal based on AES3, based on both detected results (sampling frequency and transmission rate).

Abstract: Data divided by delimiters representing the boundaries of the data is stored in a data memory. Instructions each including designation of a delimiter are stored in an instruction register. A control circuit decodes an instruction output from the instruction register, and repeats processing of the data read out from the data memory in accordance with the decoded instruction every time the data is read out therefrom. A delimiter detector outputs a coincidence signal when it detects that a delimiter which coincides with the delimiter in the instruction is present in the data read out from the data memory. When this coincidence signal is input to the control circuit, the control circuit ends the processing which has been performed in accordance with the instruction.
