A decoder is provided for four channel FM stereophonic composite signals including a first pilot signal, a main channel signal, a first sub-channel signal suppressed carrier amplitude modulated on a first subcarrier having a frequency twice that of the first pilot signal, a second sub-channel signal suppressed carrier amplitude modulated on a second subcarrier having the same frequency as the first subcarrier and having 90.degree. phase difference with respect to the first subcarrier, a third subchannel signal suppressed carrier amplitude modulated on a third subcarrier having a frequency twice that of the first subcarrier, and a second pilot signal indicative of the four channel stereophonic signal broadcasting mode and with a frequency interposed between the frequency bands of the first and third subcarriers; which decoder comprises a control signal generator controlled by the first pilot signal and producing first and second control signals in predetermined phase relation to the first pilot signal and with frequencies that are respectively equal to, and twice the frequency of the first pilot signal, a signal combining circuit supplied with the first and second control signals for producing a switching signal, and a switching circuit controlled by the switching signal for detecting the second pilot signal in the four channel FM stereophonic composite signals. When the second pilot signal is thus detected, signals from the control signal generator are employed for demodulating the four channel FM stereophonic composite signals into the corresponding four discrete audio signals; whereas, when the second pilot signal is not detected, for example, in the case of the reception of two channel stereophonic broadcast transmission, the aforesaid second control signal is employed for demodulating the two channel FM stereophonic composite signals into the two corresponding discrete audio signals.

Disclosed is a technique for quickly detecting a defect of a portion welded by laser beam welding. Specifically disclosed is a welding step in which a welding device is used, the welding device welding an object to be welded with a pulsed laser. In the welding step, a first photodetector receives only infrared rays having a wavelength allowing detection of a keyhole formed in a molten pool from among infrared rays radiating from a welded portion during the welding of the object, and an analyzer determines quality of the welded portion on the basis of intensity of the infrared rays received by the first photodetector.

There is provided a plasma processing apparatus capable of stably generating plasma by suppressing oscillation of a plasma potential, and capable of preventing contamination caused by sputtering a facing electrode made of metal. A high frequency bias power is applied to an electrode within a mounting table for mounting a target object thereon. An extended protrusion 60 is formed at an inner peripheral surface of a cover member 27. The extended protrusion 60 is formed toward a plasma generation space S and serves as a facing electrode facing an electrode 7 within a mounting table 5 with the plasma generation space S therebetween. A ratio of a surface area of the facing electrode with respect to that of an electrode for bias (facing electrode surface area/bias electrode area) is in a range of from about 1 to about 5.

Provided is a method of manufacturing a battery having an electrode module including: a positive plate having a cathode collector portion formed by attaching a lead member to a cathode substrate made of a foamed metal plate; and a cathode collector plate welded to the cathode collector portion. The method includes: a pre-welding positive plate forming process of forming a pre-welding positive plate, which is the positive plate before welding, such that the pre-welding positive plate has a projection projecting from a pre-welding cathode collector portion, which is the cathode collector portion before welding; and a welding process of melting a pre-welding cathode collector plate to weld it to the projection. In the pre-welding positive plate forming process, the projection is formed into such a shape that the condition that S≦1.3W is satisfied, where W and S represent the width and the circumferential length of the projection, respectively.

A network system enables controlling an image input device without requiring a driver that depends on the computer environment. A client terminal has a component that acquires a web page having an embedded scanner control script that controls image input from a scanner; a component that sends an image acquisition request through an interface board to the scanner as controlled by the scanner control script; and a component that gets an image from the scanner as a response to the image acquisition request as controlled by the scanner control script. The interface board receives the image acquisition request, and sends the image scanned by the scanner based on the received image acquisition request to the client terminal.
