PURPOSE: To utilize the inner volume of an expensive pressure vessel effectively by composing a reverse cup-shaped heat insulating structure being disposed between a heater and a pressure vessel of one or plurality of unit heat insulating structures having inner and outer heat insulating layers thereby making thin the entire heat insulating structure. CONSTITUTION: The sintered graphite innermost layer of a heat insulating structure normally has a reverse cup-shape and also functions as a structural support when a heat insulating structure is formed. When unit heat insulating structures are assembled, a graphite cloth, a flexible graphite sheet, a carbon based cloth, a metal foil, a ceramic based cloth, a metal foil a ceramic based felt, and a metal foil are arranged sequentially on the outer layer of a support, i.e., the sintered graphite. The graphite cloth is secured through graphite cement to the support and others are secured through some adhesive means, e.g. the outermost each layer of metal foil is secured by a heat resistant tape, thus securing the heat insulating structure to the support.

Heat-insulating structure of internal heat type high-temperature high-pressure device

PURPOSE:To reduce loss of A drive force and make smooth rotation possible by disposing a scraper at a position of a drive wheel just before biting a track belt, installing it at a rear arm, and containing part of it in a circular groove in the outer circumference of a rim. CONSTITUTION:Snow is carried to the side of a rear arm 14 by rotation of a track belt 18, and in biting it into a circular groove 2, the snow getting into a rim 25 is eliminated by a blade just before it is bitten because a scraper 30 is provided at this position, so the blade can eliminate snow easily. The blade advances toward a rear axle 11 to get in contact with snow perpendicularly to a tangent of the rim 2. so it can be eliminated securely without requiring an excessive force. As a result, snow is not allowed into a space 29 formed between the rim 25 and the inner surface of the track belt 18, but the rotation radius of the rim 25 is constant, thereby less of a drive force can be reduced, and the track belt 18 can be rotated smoothly.

PURPOSE:To realize rapid and smooth turning with a small rotating radius and increase driving force by making an endless belt wider than the width of a driving wheel, deflecting the part provided on the lateral both end parts and not supported by the driving wheel to conduct bank running. CONSTITUTION:At the time of turning, a vehicle body is banked as general motorcycles. At this time, the both side end parts of an endless belt 14 are extended longer than the width between left and right engaging members to form a part not supported by a driving wheel 13, so that this part is easily deflected to facilitate the banking. As the earthing area of the endless belt 14 during turning is extended, the driving force is increased, allowing rapid and smooth turning. By the use of the wide endless belt 14, the face pressure of the earthing face is reduced, and also the earthing area of the endless belt 14 during running can be increased in regardless of turning and straight running to increase the driving force.

Snow running vehicle

PURPOSE:To rapidly and efficiently perform design evaluation, by providing a mis-design simulating means which simulates the mis-design of a device to be targeted for the design evaluation, and a simulation control means which controls the execution of the above means. CONSTITUTION:What kind of malfunction in which function is generated by the mis-design, is registered in the mis-design simulating means 12. Next, a test program is executed without performing a mis-design simulation, and the fact that a test is completed normally if no mis-design exists, is confirmed. Following that, the execution of the mis-design simulation is instructed, then the test program is executed. Thus,it is possible to recognize influence desired to know on the test program only for the mis-design.

Design evaluating system for device

Skate (1) polyvalent for drones comprising two support bars (2), joined together by two tie bars (3), two tie rods (4) attached to the tie bars (3), a front bar ( 12), fixed at one end of the coupling rods (4), and means for attaching to the drone (9), where each coupling rod (4) is movable along the length of the two connecting rods ( 3) and are fixed in different positions of said tie bars (3) and the fastening means to the drone (9) are movable along the coupling rods (4). With the above configuration, the skate is adaptable to a plurality of drone geometries allowing to place different devices associated with the front bar (12) in most of the existing drones, with a quick change of the skate (1).
