  • Patent number: 5630574
    Abstract: Interference between a spring and a shaft is prevented in a torque shock absorber device which uses a coil spring. The torque shock absorber device has a shaft which is fixed on a base plate, and a sleeve is installed which is free to rotate against the shaft. On the sleeve, a torque transmission part is installed. One end of the coil spring is inserted and fixed in a slot of the shaft. The coil spring is wound on a peripheral part of the shaft and sleeve, and the other end is fixed on the torque transmission part. When torque is applied on the torque transmission part, the sleeve is rotated with the wound coil spring and no friction is generated between the sleeve and shaft.

  • Patent number: 5467943
    Abstract: In a window structure equipped on the side walls of a cabin in the body of an airplane, a transparent board is mounted on the outer portion for sealing the pressure inside the cabin. A dust cover is mounted in the inner side of the transparent board sealing the pressure, and a shade 80 which is able to take an up and down movement is mounted on the cabin side of the dust cover for blocking outer incident light. The dust cover comprises of a transparent resin board and a non-elastic film stuck on the surface of the transparent resin board facing the shade. The acrylic resin used as the material of the transparent resin board expands by absorbing the water in the air, but by the operation of the non-elastic film, the dust cover bends toward the outer direction F of the body, and will not interfere with the locus L.sub.1 of the up and down movement of the shade.

  • Patent number: 5435372
    Abstract: The folding doors 100 includes of a first door panel 150 and a second door panel 110, the first door panel 150 being attached to the door opening portion of the wall rotatively by a pin 150. The second door panel 110 is attached to the first door panel 150 by a hinge 4. A guiding device 120 is mounted on the upper portion of the second door panel 110. The guiding device 120 holds a slider 122 and a rotary damper 200 for damping the rotation of the axis holding the slider. The slider 122 slides without rotating inside the guiding rail mounted on the upper portion of the door opening portion. The second door panel 110 rotates by opening/closing action, so by damping this relative rotation with the rotary damper 200, the folding doors could be closed quietly.

  • Patent number: 5287130
    Abstract: The present invention offers a picture projecting device which projects a clear picture even in a bright environment by cutting out the influence of outer light, regardless of the kind of projector used.On the surface of a screen 20 inside an airplane, a first polarizing film 22 is put on. Further, a second polarizing film 32 is put on the input portion of outer incident light such as window glasses 9 or cover 8 of the room light. The second polarizing film 32 has the same polarizing trait as that of the first polarizing film 22, but they are placed so that the plane of polarization of the second polarizing film 32 differs from that of the first polarizing film 22 by 90.degree.. The outer incident light H passing through the second polarizing film 32 enters the screen 20 as a polarized transmission light h1. The light will be reduced completely by the first polarizing film 22 placed on the screen and will not reflect.

  • Patent number: 5146065
    Abstract: An electricity supply device, connected to an electric contact of a heater on a tray, is disposed on the side wall at the upper part of a support member which supports and guides a tray and which is formed on the side wall of a receiving chamber. The electricity supply device has a) a conductive plate spring placed in pressure contact with an electric contact of a heater and b) a conductive pin connected to a power source and is embedded into a plastic mold. The plastic mold is disposed into a casing which is mounted to the side wall of the receiving chamber to secure an insulating property. The plate spring makes positive contact with a contact of the heater.

  • Patent number: 5145128
    Abstract: A storage section for storing a video monitoring equipment for an airliner and the video monitoring equipment which moves to a visible position are connected by two long cylindrical springs. One of the springs is urged in the direction of the storage section of the airframe. The other spring is made of a shape-memory alloy on which a specific shape is memorized in heated condition. When the second spring is heated and takes the specific shape, the video monitoring equipment is moved to the visible position together with the move of the second spring going against the urging force of the first spring. When the heating of the second spring is stopped, the video monitoring equipment is moved to the storage section along with the movement of the first spring by the urging force of the first spring.

  • Patent number: 5037498
    Abstract: A method for continuously molding a honeycomb panel having a sandwich structure wherein a plastic composite is bonded to both surfaces of a honeycomb-shaped core member. A long honeycomb sandwich panel is formed by repeating the following steps:(1) laminating a prepreg to the upper and lower surfaces of a band-like honeycomb core member to form a band-like blank;(2) feeding the band-like blank between a pair of upper and lower hot plates having a rectangular plane shape;(3) pressurizing the hot plates to apply pressure and heat to part of the band-like blank for a preset time; and(4) relieving the pressure exerted in the hot plates and feeding the band-like blank by a distance corresponding to a partial length of the hot plates.
