Title: Image fiber
Inventor: SETO KATSUYUKI
IPC: G02B6/06
Filed: 1991-03-29
Abstract: PURPOSE:To provide an image fiber capable of transmitting an image of uniform color by transmitting all wavelength areas. CONSTITUTION:Refractive indexes of cores 10 in an image circle 1 are made gradually higher from the center toward the outside, and refractive indexes of clads 12 are fixed, therefore, the core placed in the relatively outer side has a larger refractive index difference between the core and the clad. Though cores placed in the vicinity of the outside part of the image circle are apt to deform or bend by the problem of image fiber production, the wavelength to be cut off is suppressed to transmit all wavelength areas because the core placed in the relatively outer side has a larger refractive index difference between the core and the clad, thus, a picture of stable color is obtained.

Title: Magnetic recording and reproducing device
Inventor: UENO HIDEMI
IPC: G11B5/027
Filed: 1983-05-20
Abstract: PURPOSE:To reduce shock sound at application of power at sound recording state or reproducing state by providing a circuit bringing temporarily an amplifier to the interrupting state just after application of power. CONSTITUTION:The amplifier 6 is brought into the operating state only when an ON signal is outputted from a terminal S. In applying power to a sound recording and reproducing changeover switch S1, a transistor (TR) 163 is turned on while a capacitor 165 is charged only and a potential of a point M is nearly coincident with a voltage P by the TR164. When the sound recording and reproducing changeover switch S1 is thrown to the position (a), since a voltage Vcc is applied to a resistor 154, a capacitor 155 is charged, a voltage at the point M increases slowly by taking the voltage P as the start point and when the S1 is thrown to the position (b), since the capacitor 155 is dischrged via resistors 154, 156, the voltage at the point M is decreased slowly by taking the voltage P as a start point. Thus, the amplifier 6 is interrupted while the voltage M changes from the voltage P to the voltage O or from the voltage P to the voltage Q and no shock sound is outputted to a terminal B.

Title: Method and apparatus for continuous casting and rolling
Inventor: NAKAMURA KOJI
IPC: B22D11/06
Filed: 1986-04-18
Abstract: PURPOSE:To produce a rolling directly from a molten metal with a short stage and to considerably reduce cost by casting an unsolidified ingot having a large sectional area, crushing the ingot to gradually decrease the sectional area and rolling the solidified ingot. CONSTITUTION:The molten metal 3 in a tundish 2 is poured into a roll gap part of casting rolls 1 to form the unsolidified ingot 5A having the large sectional area. The ingot is then cooled by a cooling water sprayer 4. The ingot 5A is successively decreased in the sectional area by crushing rolls 6, 7, 8 and cooling water sprayers 9, 10, 11 to form the thoroughly solidified ingot 5B. The ingot 5B is then rolled by using rolling mills 13, 14, 15 to complete a hot strip 5C. The rolling material is thus produced directly and continuously from the molten metal 3 with the shorter stage and therefore, the initial cost and production cost are considerably reduced.

Title: Learning system for serial connection type recurrent neural network
Inventor: MIYAZAWA HIDETAKA
IPC: G06G7/60
Filed: 1993-04-16
Abstract: PURPOSE:To provide a serial connection type recurrent neural network (RNN) learning system capable of executing learning based upon an error backward propagation(BP) method with high capacity and sufficiently displaying its original capacity. CONSTITUTION:Learning algorithm by the BP method based upon a complete connection type RNN status equation is introduced to the serial connection type RNN. The active initial value of an output neuron 4 is used as a teacher signal in an initial state, and in an advanced state, the updating of a connection coefficient is required and a proper error value between the output value of the neuron 4 and the input value of the teacher signal is found out in accordance with a prescribed evaluation function. Then the proper error value is applied to other neurons 1 to 3 excluding the neuron 4 as an external input through a data access terminal P. Since the external input obtained when the error value is small does not exert influence upon the original capacity of the serial type RNN, the learning capacity of the serial type RNN can be improved.
