Title: Automatic sound volume control method for telephone set and controller therfor
Inventor: OGISO MICHINORI
IPC: H04M1/60
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To optimize automatic sound volume adjustment of the telephone set under various conditions, without using any special sound pickup other than the telephone set. SOLUTION: A characteristic of speeches that between a caller and its opposite party less make simultaneous utterance is utilized in usual telephone communication. When a voiced received signal discrimination device 9 discriminates a received signal to be a voice signal, since this means that the speech opposite party is making utterance, the calling person is not making utterance. Thus, a transmission signal 5 detected by a transmission signal level detector 7 is only a surrounding noise with a talker voice signal excluded therefrom. Only when the voiced received signal discrimination device 9 discriminates a received signal to be a voice signal, does a computing element 2 calculate the result of detection of the transmission signal level detector 7 stepwise, or continuously or locally to change a gain of a variable gain amplifier 3 stepwise, or continuously or locally, thereby attaining automatic sound volume control of the reception signal 6 in response to the surrounding noise level.

Title: Rectangular plane speaker
Inventor: TAKEWA HIROYUKI
IPC: H04R9/04
Filed: 1987-04-01
Abstract: PURPOSE:To prevent a resonance mode by fitting a drive cone, in which a diaphragm side is wide-based and an aperture surface is oval, between a rectangular plane diaphragm and respective voice coil bobbins with a long diameter direction to the short side direction of the diaphragm. CONSTITUTION:A drive cone 14 is formed into wide-base shape from one edge to other edge in which the aperture surface of one edge is circular and the aperture surface of other edge is oval. The cone 14 is fitted, by arranging an oval aperture surface, to the side of a diaphragm 9 with the long diameter direction of the aperture surface to the short side direction of the diaphragm 9. Since constitution is executed like this, primary and secondary resonance modes of the diaphragm 9 do not occur since an action point to eliminate two modes is driven. Since the long diameter of the cone 14 is >= 55% of the length of the short side of the diaphragm 9, and a driving force functions at both of the part of the loop of a mode and the part of the back of the mode, the resonance mode can be also suppressed. Consequently, the piston motion area of a rectangular plane diaphragm is enlarged, and a sound pressure frequency characteristic can be flattened.

Title: Method and apparatus for displaying slave picture of television system
Inventor: YOSOMONOYA IZUMI
IPC: H04N5/347
Filed: 1988-03-31
Abstract: PURPOSE:To keep the horizontal high resolution of a slave picture by deciding the timing of readout start of an image pickup signal in vertical and horizontal directions from each solid-state image pickup element depending to which position of the display picture of each video image by each solid-state image pickup element is to be displayed. CONSTITUTION:Since the vertical signal is read by adding plural predetermined lines by a vertical direction signal readout means, the vertical direction height of a slave picture is reduced. In the case of reading out in the horizontal direction, since the data is read at a higher rate than the time in a full horizontal effective scanning period during a period being a fraction of the horizontal effective scanning period by the horizontal direction signal readout means, the horizontal width of the slave picture is reduced. Then the timing of the readout start in vertical and horizontal directions is decided by a timing decision means for each solid-state image pickup element. Thus, plural video images by plural solid-state image pickup elements are displayed simultaneously on the display picture with reduction and the horizontal resolution of the slave picture is kept high.

Title: Fluidized-bed furnace
Inventor: NOMOTO HIROKI
IPC: C21B13/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To extremely reduce an amount of powder fluid discharged out of a fluidized-bed furnace together with gas in the furnace by providing a plurality of exhaust gas outlets between a top center of the furnace and a straight shell of an upper part side of a furnace body. SOLUTION: A predetermined amount of gas in the furnace is exhausted from a free board 16 of an upper art of a fluidized bed 13 via an exhaust gas duct 5 in a reaction process. Then, a position of the duct 5 is not formed at a center of a mirror plate 2 for forming a furnace top, not a straight shell 3 of an upper part side of a furnace body but disposed therebetween. Thus, there is small possibility of exhausting powder fluid out of the furnace accompanied with the gas in the furnace to be exhausted from the duct 5. And, since a retention time in the furnace of powder fluid-like material, i.e., reducing time and carbonizing time can be sufficiently ensured long, a transfer ratio of iron oxide to an iron carbide is extremely high. Accordingly, such a fluidized- bed furnace 1 can be particularly suitably used as a large-sized fluidized-bed furnace.
