Title: Automatic transmission
Inventor: AIKAWA HIROSHI
IPC: F16H61/04
Filed: 1988-09-21
Abstract: PURPOSE:To automatically mitigate a shock when a clutch is engaged by making the transfer torque capacity which is the sum of the static hydraulic component and the centrifugal hydraulic component higher than the engine brake torque regardless of the input rotating speed. CONSTITUTION:The clutch static oil pressure is set to a fixed oil pressure, e,g., 2kg/cm<2>, corresponding to the middle between the maximum value and the minimum value of the engine brake torque in advance, and the clutch transfer capacity given by the sum of the centrifugal oil pressure increased as the input rotating speed is increased and the static oil pressure is set to be invariably higher than the engine brake torque. The engine brake torque is increased nearly in proportion to the rise of the input rotating speed, while the clutch oil pressure (static oil pressure + centrifugal oil pressure) is increased at the secondary function, thus the clutch oil pressure curve does not intersect with the engine brake torque characteristic curve. The slip of a clutch can be prevented when the clutch is engaged, and a shock can be mitigated.

Title: Signal detecting method
Inventor: YAMADA SATOSHI
IPC: G06N3/02
Filed: 1989-09-14
Abstract: PURPOSE:To process a large quantity of data with high efficiency by inputting a projecting part and its peripheral data detected out of the time series data into a multi-layer neural network where each inter-layer connection constant is previously learnt and deciding whether the projecting part is equal to a signal to be detected or not based on the output value of the neuron network. CONSTITUTION:A neuron network consists of a multi-layer, e.g., 3 layers which learnt already each inter-layer connection constant via the adverse transmission of an error. Thus the connection is secured among all units set between an input layer 1 and an intermediate layer 2 and between the layer 2 and an output layer 3. Then the Fourier transformation, for example, is applied to the time series data including a signal to be detected for elimination of the noises. Then a projecting part is detected and this projecting part and its peripheral data are inputted to the multi-layer neuron network. Based on the output value of the neuron network, it is decided whether the projecting part is equal to the signal to be detected or not. Thus it is possible to automatically detect the signal to be detected with high accuracy and therefore to process a large quantity of data with high efficiency.

Title: Optical submarine cable repeating system
Inventor: IWAMOTO YOSHINAO
IPC: H04B10/29
Filed: 1986-10-09
Abstract: PURPOSE:To contrive to miniaturize a repeater by constituting plural repeaters in such a way that regenerative repeating is applied to each pair of n-pair of optical fibers through the regenerative repeating function of the repeaters arranged at an interval being plural number of times of the unit repeater interval. CONSTITUTION:In applying relay transmission through the use of n-pair of optical fibers in general, 2n/k sets of regenerative repeating circuits are mounted in a repeater, where (k) is a divisor of the number (n). Each repeater is applied with regenerative repeating to n/k-pair of optical fibers and relays the remaining k-1/n pairs of optical fibers not through the regenerative repeating circuits. For example, in a transmission system using 4-pair of optical fibers 2, the number of regenerative repeating circuits in one repeater 1a is decreased from 8 circuits into 4 circuits, and instead a repeater 1a is provided newly at a location corresponding to an adjacent joint box to attain the recovery/relay to the remaining 2-pair of optical fibers. Thus, 4 sets of regenerative repeating circuits are enough for the application to be mounted in the repeater 1a thereby miniaturizing the repeater.
