Title: Rudder wing
Inventor: ARAKAWA HARUHIKO
IPC: B64C9/02
Filed: 1991-12-09
Abstract: PURPOSE:To obtain a rudder wing which is free from tip stall and has no decrease in dynamic lift caused by a gap at a wing root part by shaping the rudder wing mounted on a body with a circular cross section to have a planar form with an advancing angle and to mount with a forward tilted hinge line for driving. CONSTITUTION:A rudder wing to be mounted on a body with a circular cross section such as flying object, which has a rudder wing 1 with an advancing angle and a forward tilted hinge line 2 causes no tip stall at a wing tip 4 up to a large rudder angle while a gap 6 is reduced between a rear part of the hinge line 2 at a wing root part 5 and the body 3. Thus, a dynamic lift and a rolling moment can be retained thereby allowing a higher tip opening and a stable rolling control. With the control of the tip stall, increase in resistance can be lowered thereby achieving an increase in the cruising range.

Title: Boresight alignment plate
Inventor: ISHII TAKASHI
IPC: G01R29/10
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To obtain a boresight alignment plate that can obtain a high alignment accuracy with a small size with reference to a waveform, by arranging two flat plates, which comprises a step at a 1/4 wavelength and whose area and shape are mutually identical, side by side. SOLUTION: Electromagnetic waves, which are radiated to a space from a transmitter are reflected by a boresight alignment plate 9 on a rotating base, and they are received by a receiver via a receiving antenna. At this time, the synthetic radar reflection cross-section(RCS) characteristic of flat plates 9a, 9b, of the same area and the same shape, at the boresight alignment plate 9 becomes array synthetic patterns having an interval (a), and an optical path length becomes twice that of an ordinary array antenna. At this time, when a step (d) is set at a 1/4 wavelength, two RCS patterns are synthesized at an opposite phase. As the characteristic of the synthesized RCS pattern, an amplitude becomes minimum when the electromagnetic waves are incident perpendicularly to the boresight alignment plate 9.  In addition, its level with reference to an angle is very steep and very highly sensitive near a perpendicular incident direction. Consequently, it is possible to obtain the boresight alignment plate, whose size is small and whose alignment accuracy is high.

Abstract: PURPOSE:To obtain a porous hollow yarn membrane whose fine pore diameter is controllable by using a poor solvent of polymers for a raw liquid consisting of polymer able to be formed in a membrane and a soluble organic solvent for spinning into a thread. CONSTITUTION:A combination of a polymer able to be formed in a membrane and an organic solvent in which the polymer is soluble, e.g. a combination of polysulfone with dimenthylamide, dimethylformamide is used as a raw liquid for spinning into a thread, and a part of the soluble organic solvent, which is used for a polymer is substituted with a poor solvent. As the poor solvent, for example, lower alcohols e.g. methanol, ethanol, etc., ketones, e.g. acetone, methyl ethyl ketone, etc., which are commonly used as organic solvents compartible with water or an aqueous liquid for coagulation bath, are used. Dry-wet-type spinning is carried out by a conventional method and at that time a core liquid, which is a spinning raw liquid coagulating liquid, can be used and the core liquid is sprayed together with the spinning raw liquid. Hollow yarn membranes with various membrane pore diameter are prepared by only altering the addition amount of the poor solvent.

IPC: F16H35/10
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To improve sensitiveness and working precision by arranging a gear type engaging part on one side of an outer ring inner circumferential face or an inner ring outer circumferential face arranged on the inner circumference side freely relatively rotationally and fixing a spring member to be elastically engaged with the engaging part on the other side. SOLUTION: When rotational torque is inputted, a star spring steel 21 is not elastically deformed greatly when a dimension of the torque is less than the predetermined value, and an outward engaging part 22 is not recessed beyond a projection part 6 in a gear type engaging part 4, so that an outer ring 1, the spring steel 21, and an inner ring 11 are rotated integrally and rotational torque is transmitted. When the rotational torque becomes the predetermined value or more, the spring steel 21 is elastically deformed greatly, and the engaging part 22 is recessed greatly over the projection part 6, so that the ring 1, the spring steel 21, and the ring 11 are rotated relatively, and transmission of the rotational torque is restricted. Therefore, dispersion of torque during an operation can be reduced, and improvement in sensitiveness and working accuracy can be accomplished.

Abstract: PROBLEM TO BE SOLVED: To change an immersion time of an aluminum plate in a treating liquid by moving the location of a carrying roll, and change treating amounts of respective processes for a switching of product kinds by changing the treatment time independently for respective treatment tanks without accompanying the changes of a treatment strength and a carrying speed. SOLUTION: For example, a treating time changing means which changes a treatment time independently for respective treatment tanks performs a treatment time change by changing an immersion length of an aluminum plate P in a treatment liquid.
