A method for concentrating a water-soluble organic material wherein a mixture of the water-soluble organic material with water is distilled in a distillation column (11), and the fraction from the top (11a) of the distillation column (11) is separated by the use of a membrane separator (14) into a permeated vapor (F2) and a non-permeated vapor (F3), which comprises once condensing the fraction to form a condensate, heating the condensate in an evaporator (13) to generate a vapor (F1) having a pressure higher than the operation pressure for the distillation column (11), and introducing the vapor (F1) to the membrane separator (14), thereby separating water from the mixture.

An elevator system uses a supercapacitor to store electric energy. Furthermore, the supercapacitor can be used as a source of reserve power in emergency situations, such as power failures. The supercapacitor is connected together with three switching branches to a rectified signal of the power supply of the motor. By closing and opening the switches, the supercapacitor can be charged when the motor load is small. When the motor load is large or when the power supply fails, the electric energy contained in the supercapacitor can be discharged for use by the motor. In an emergency, the motor drives the elevator at a speed lower than normal, and therefore a supply voltage lower than normal is sufficient. Also, energy obtained from braking of the elevator can be stored in the supercapacitor, which has a storage capacity of considerable magnitude as compared to an ordinary capacitor. By applying the invention, the energy consumption of the elevator can be reduced because the waste energy obtained from the power supply can be stored and utilized when more energy is needed.

The present invention provides a biped (two-footed) walking mobile system, its walk controller, and walk control method therefore, which are to realize enhancing an walk stability, as well as a consumed energy saving. A walk controller (30) of a biped walking mobile system forms a gait data by a gait forming part (33) based on parameters from a gait stabilizing part (32), and drive-controls drive means of respective joint portions (15L, 15R–20L, 20R) of each leg portion based on said gait data. In this case, the walk controller (30) is so constituted as to selectively witch a powered mode to conduct ordinary drive-control and a passive mode to drive-control the drive means similarly with passive joints, whereby drive-controlling respective joint portions. The walk controller (30) preferably switches the drive and passive modes with respect to, for example, joint portions of knee and foot portions, or switches to the powered mode for kick-up and landing during walking motion, and to the passive mode for a free foot state.

The present invention realizes efficient dust removal in an optical apparatus in such a manner that a single circuit drives a plurality of dust reduction optical elements to vibrate. When the optical elements have different resonance frequencies, it can be configured such that the vibration exciting frequency can be changed in a range including the resonance frequencies of all the optical elements. In this case, the optical element driven can also be switched according to the change in frequency so that only the optical element having a resonance frequency close to the driving frequency will be driven. Alternatively, it can be configured such that the driving time or applied voltage can be changed according to the characteristics of the optical element driven.
