The invention is directed to a liquid heater for rapidly heating a liquid without overheating the liquid. The liquid heater comprises a liquid flow channel having a passage through which liquid flows, a heating part disposed outside the liquid flow channel, a heat reflecting part facing a heat radiating side of the heating part, and a cooling part through which a cooling medium flows adjacent a reverse side of a reflecting surface of the heat reflecting part for cooling the heat reflecting part. Radiant heat not absorbed in the liquid is reflected by the heat reflecting part. The heat reflecting part reflects radiant heat cooled by the cooling part so that the body of the liquid heater and peripheral members are maintained at a temperature not higher than a predetermined temperature to prevent overheating the liquid.

Liquid heating method, liquid heating apparatus, and heated liquid supplying apparatus

Provided is a liquid heating apparatus capable of heating fluid such as peroxosulfuric acid solution to high temperature in a short time. The heating apparatus includes: a flow channel member forming a flow channelallowing liquid to flow and having flow channel thickness of 10 mm or smaller, the flow channel member composed of material transmitting near-infrared rays; and a near-infrared heatersplaced over the outside of at least one of opposite flow channel surfaces of the flow channel and heating the liquid in the flow channel. The liquid flowing through the flow channel is instantaneously and evenly heated using near-infrared rays. It is preferable that spacersbe further provided within the flow channelin order to limit the volume of the flow channel. Since not only the residence time in the heating apparatus can be shortened but the possible largest heat transfer area can be also maintained by decreasing the volume of the flow channel of the heating apparatus and by increasing the flow velocity in the heating apparatus, it is possible to increase the temperature of liquid to be heated to high temperature in a very short time even if the preset temperature of heat transfer surfaces is low.

Liquid heating apparatus and liquid heating method

Provided are a system and method capable of providing a sulfuric acid solution containing peroxosulfuric acid for use in cleaning even in an installation-limited space such as a clean room while suppressing the fluid pressure in a heating part such as a rapid heating heater. The system comprises: an electrolytic part for electrolyzing a sulfuric acid solution to produce peroxosulfuric acid; a first reservoir for storing the sulfuric acid solution; a circulation line for circulating the sulfuric acid solution between the electrolytic part and the first reservoir; a cleaning apparatus for cleaning a cleaning object by use of the sulfuric acid solution containing peroxosulfuric acid; a supply line for sending the sulfuric acid solution electrolyzed in the electrolytic part to the cleaning apparatus; a heating part for heating the sulfuric acid solution to be used in the cleaning apparatus, the heating part being interposed in the supply line on the upstream side of the cleaning apparatus; and a second reservoir which is interposed in the supply line on the upstream side of the heating part. Since the second reservoir and the heating parts are positioned spatially above the level of the first reservoir, the electrolytic part and the circulation line, the device can be disposed with good space efficiency while preventing application of a high fluid pressure to the heating part or the like.

Functional solution supply system

A wear of an electrode is prevented as much as possible, thereby efficiently electrolyzing a sulfuric acid solution and the like. An electrolysis method includes: passing an electrolytic solution through an electrolysis cell including at least a pair of an anode and a cathode; and supplying the electrodes with an electric power, so as to electrolyze the electrolytic solution, wherein a viscosity of the electrolytic solution is set in a range in response to a current density upon the electric power supply to carry out the electrolysis. The viscosity of a sulfuric acid solution as the electrolytic solution is equal to or less than 10 cP when the current density is equal to or less than 50 A/dm, the viscosity of the sulfuric acid solution is equal to or less than 8 cP when the current density is from more than 50 to 75 A/dm, and the viscosity of the sulfuric acid solution is equal to or less than 6 cP when the current density is from more than 75 to 100 A/dm. Particularly when a highly-concentrated sulfuric acid solution is electrolyzed at a high current density using diamond electrodes, the electrolysis process can be carried out highly efficiently while a wear of the electrode is reduced.

Electrolysis method

In a flap operating system, left and right actuators for operating left and right flaps are synchronized with each other by left and right pulleys and first and second synchronizing cables wound in an X-shape around the left and right pulleys. If one of the hydraulic actuators fall into a free failure or fails due to sticking, a difference is generated between the rotational angles of the left and right pulleys. When the difference exceeds a threshold value, the operations of the left and right actuators are stopped, whereby an excessive load is previously prevented from being applied to a main wing structure or the flap operating system.

Flap operating system

A first cylinder drives a flap to a predetermined down position. Strain gages detect strains at each part of the flap while a load that corresponds to the down position is applied to the flap by a second cylinder that has been moved by an XY table so as to track the down position. Accordingly, actual aerodynamic forces are precisely reproduced by applying a load having a size and a direction that correspond to the down position of the flap. Thus, a stationary load test, a dynamic load test, and a durability test of the flap can be carried out automatically with a small effort and in a short time.

Flap test system

A flap mounted on a tapered main wing of an aircraft, is supported by at least two link units. The link units are formed into analogous shapes with an analogous size ratio equal to the ratio between corresponding chord lengths of the main wing. As a result, the amounts of protrusion of the flap are varied in the span direction in accordance with the analogous size ratio, and the flap performs a three-dimensional motion such that it is moved in the span direction while being retracted and lowered. Thus, the flap can be moved to protrude to an optimal position and through an optimal angle according to the chord lengths of the main wing. When the flap is a slotted flap, an appropriate slot width can be ensured at each of the portions in the span direction, whereby the aerodynamic characteristic of the flap mounted on the tapered main wing can be uniform in the span direction.

Flap operating device

A flaperon operating device having a center pulley and a slider supported on a center shaft. When the center pulley and the slider are rotated about the center shaft, left and right driving pulleys are rotated in the same direction, whereby left and right flaperons are operated in opposite directions to provide aileron functions. When the slider is slid rearwards on the center shaft by an actuator, the left and right driving pulleys are rotated in opposite directions, whereby both the left and right flaperons are lowered to provide flap functions. If the left and right flaperons are lifted or lowered by a very small angle in the same phase by the actuator, boundary layers on main wings can be controlled to reduce the drag.
