Abstract: An optical information reading apparatus is provided which is made of an assembly of a barcode reader and a personal digital assistant (PDA). The barcode reader and the PDA are joined through an attachment. The barcode reader includes a joint detector working to detect the joint to the PDA and a communication system establishing communication with the PDA. The barcode reader works to transmit barcode data to the PDA through the communication system only when the joint detector has detected the joint to the PDA, thereby providing ease of operability, useability, etc.

Abstract: 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.

Abstract: 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.

Abstract: 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.
