摘要:
A class D amplification device that prevents beats caused by switching operations of a switching power supply and a class D amplifier from causing noise within a voice band, enables easy control over power supply operations, and offers low power loss is provided. The amplification device includes a unit that generates a reference clock, a switching power supply that operates at a first frequency at which the frequency of the reference clock is divided, and a triangular wave generation unit that operates at a second frequency higher than the first frequency at which the frequency of the reference clock is divided. The amplification device further includes a class D amplifier that performs a switching operation with a pulse whose width has been modulated according to the input signal.

A display apparatus includes a display unit for displaying images, a backlight unit disposed behind the display unit for illuminating the display unit, an inverter unit for electrically controlling the backlight unit, a controller unit for controlling the inverter unit and the display unit, and a power supply unit having an exothermic heat distribution for supplying electricity to the inverter unit and the controller unit. The inverter unit and controller unit are disposed behind the backlight unit and the power supply unit is disposed on a side of the display unit, backlight unit, inverter unit and controller unit. The display unit, backlight unit, inverter unit, controller unit and power supply unit are disposed in a common housing. The inverter unit and the controller unit are arranged behind the backlight unit. An insulating member is further disposed between the power supply unit and the display unit at a position corresponding to a region of relatively large exothermic heat of the power supply unit, and the insulating member is disposed at a diagonal position with respect to the inverter unit. The display apparatus may be supported by a support structure including vertically tilting and laterally turning mechanisms.

A selectively water-permeable hydrolyzed membrane characterized in that it is mainly made of a material which can generate a carboxyl group by hydrolysis and that a part of the material is hydrolyzed to have carboxyl groups, which may be further coated with a hydrophilic polymer. The above membrane is useful as a selectively water-permeable membrane and is applicable not only to pervaporation and vapor permeation, but also to reverse osmosis, dehumidification of air and so on.
摘要:
A method of and a device for controlling a counter of a rolled material on a multi-high rolling mill with which method and device very accurate shape control can be attained with certainty and in high responsibility. A strip shape of a rolled material in its widthwise direction on the outgoing side of the rolling mill is detected by a strip shape meter, and the detected shape and a strip thickness are synthetically evaluated using a total performance index. Operation amounts for a strip shape controlling actuator and a strip thickness controlling actuator which make the value of the total performance index minimum are always found out, and the actuators are controlled simultaneously in accordance with the operation amounts to control the strip shape of the rolled material. The apparatus comprises a saddle receiver the vertical position of which is controlled by a roll gap controlling device in accordance with an estimated value to change the gap between upper and lower work rolls of the rolling mill.
摘要:
A permeable membrane through which water or its vapor permeates selectivelynd which contains a polyion complex formed by the association by an ionic bond between an anionic polymer and a cationic polymer on the surface of the membrane and/or in the membrane. This membrane is useful in the separation of water from an aqueous solution of an organic substance or a gaseous mixture of water with an organic substance, and exhibits excellent resistance to solvent, particularly water, and a high permeation rate and a high separation coefficient.
