Abstract: This disclosure relates to a method of generating a symbol string based on an input sentence represented by a sequence of symbols. In particular, the method involves receiving an input symbol string representing a sentence, generating, using a neural network based on a sequence of dependency structure of elements in the input symbol string, an output symbol string corresponding to the input sentence. The neural network includes an encoder that converts elements of the input symbol string to a first hidden state in a form of a multi-dimensional vector, an attention mechanism that applies a weight to the first hidden state and generates the weighted first hidden state as a second hidden state, a decoder that generates a third hidden state based on at least one element of the input symbol string, an element of the output symbol string, and the second hidden state, and an output generator that generates an element of the output symbol string based on the second hidden state and the third hidden state.

Abstract: A membrane separation apparatus includes: a pump controller to control a rotational speed of a booster pump; an intake water pressure regulation valve controller to control an opening degree of an intake water pressure regulation valve; a drainage water flowrate regulation valve controller to control an opening degree of a drainage water flowrate regulation valve; and a timing adjustor to adjust timings of control by the pump controller, the intake water pressure regulation valve controller, and the drainage water flowrate regulation valve controller. When water is supplied to the membrane separation apparatus, the timing adjustor provides time lags among a control start of the booster pump by the pump controller, a control start of the intake water pressure regulation valve by the intake water pressure regulation valve controller, and a control start of the drainage water flowrate regulation valve by the drainage water flowrate regulation valve controller.

Abstract: An operation input device includes: an operation body having a handle portion. The operation body tilting around a rotation center point when a user tilts the operation axis line of the handle portion. The operation body tilting in a predetermined number of tilting directions. The operation input device including multiple detection portions, the number of the detection portions being less than the predetermined number of tilting directions of the operation body. Each detection portion outputting a first output value when the operation body tilts in a direction corresponding to the detection portion and outputting a second output value when the operation body tilts in a direction not corresponding to the detection portion. A determination device determines a tilting direction of the operation body based on information on the number of first output values and information on a part of the detection portions that have outputted the first output values.

Abstract: An operation input device includes: an operation body having a handle portion, the operation body tilting when the user tilts the operation axis line of the handle portion, and the operation body turning when the user turns the handle portion around the rotation axis line; a stopping portion that abuts on and stops the operation body so as to limit a tilting range of the operation body; a first concavo-convex portion disposed on the operation body; and a second concavo-convex portion. The second concavo-convex portion is disposed at a position corresponding to the first concavo-convex portion of the operation body when the stopping portion stops a tilting motion of the operation body. The first concavo-convex portion and the second concavo-convex portion are engaged with each other so as to restrict a turning motion of the operation body.

The engaging portion engages with a part of the body during the depressing operation of the body so that the engaging portion restricts a tilting motion of the body.

Abstract: A regeneration process in the operating method of the invention includes a first regeneration process, and a second regeneration process after the end of the first regeneration process. In the first regeneration process, a regenerant is distributed at a top of an ion exchange resin bed and simultaneously the regenerant is collected at a bottom of the resin bed, thereby generating a downward flow of the regenerant to regenerate the whole of the resin bed. In the second regeneration process, the regenerant is distributed at a bottom of the ion exchange resin bed and simultaneously the regenerant is collected at a middle of the resin bed, thereby generating an upward flow of the regenerant to regenerate a part of the resin bed.

Abstract: A method for operating a water softening device, includes: producing soft water by passing raw water downward through a cation exchange resin bed which has a depth of 300 to 1500 mm and a ratio of the depth to a diameter being 1.8 to 3; and regenerating all the bed by generating an opposite flow of a regenerant by collecting the regenerant at an intermediate portion of the bed while supplying the regenerant from top and bottom sides of thereof, wherein the regenerating includes supplying the regenerant in a volume which gives a regeneration level of at least 1 to 6 eq/L-R, to a hardness leak prevention bed having a depth of 100 mm, and the producing after the regenerating includes supplying raw water having an electric conductivity of equal to or lower than 150 mS/m and having a total hardness of equal to or lower than 500 mgCaCO3/L.
