IPC: B64G1/66
Filed: 1993-06-16
Abstract: PURPOSE:To prevent the increase of the weight of the whole of a satellite and to eliminate limitation of arrangement of a mounted device owing to the increase of a wiring amount occasioned by the increase of an amount of signal transmitted and received between devices mounted on satellites. CONSTITUTION:A U-shaped hole is formed in a honeycomb 1 of which a satellite body structure consists and the honeycomb 1 and plates 6 are bonded together with optical fibers 4 and 5 nipped thereby. Since the optical fiber is caused to pass through the honeycomb, an amount of wiring for an internal device is reduced and limitation of arrangement of devices is also reduced.

Abstract: PROBLEM TO BE SOLVED: To enable sure operation of a crew protector even in the case of unstable action of an acceleration switch by providing an integration means for integrating open/close signals output from an acceleration switch and a starting means for starting the acceleration switch when its output is within a preset range. SOLUTION: An acceleration switch 5a is opened/closed by movement of a weight caused by acceleration of a vehicle, an open/close signal of the acceleration switch 5a is integrated by an integration circuit 5b and if an output of the integration circuit 5b is judged to be within a preset range by means of a comparison circuit 5c, a collision judging part 5 starts a crew protector by means of a semi-conductor switch 22.  Owing to such constitution, even if the open/close of the acceleration switch 5a takes place intermittently due to too large movement, etc., of the weight on account of acceleration at the time of vehicle collision, the integration circuit 5b integrates and outputs the open/ close signal output in agreement of its open/closed state, the output of the integration circuit 5b is stabilized even if any abnormal open/close signal is output, and start is also carried out in its stabilized condition.

IPC: G06F15/02
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To enhance the joining strength of a heap to the substrate through resin liquid by discontinuously enclosure-forming a plurality of projections on the substrate with predetermined gaps defined between the projections, and potting resin liquid in the projections containing gaps between the projections. SOLUTION: A plurality of projections 2 with a predetermined thickness are circularly formed discontinuously by making predetermined gaps 21 therebetween in a manner encircling the operation part at the opposite position to the operation part of characters, marks, and the like to be denoted on the substrate 1 consisting of a plastics sheet or like material. Each projection 2 is formed by, e.g. screen printing means, and a ultraviolet ray curing type printing ink is most suitably employed in this process. Although transparent resin liquid 3 is polled on the substrate 1 encircled by these projections 2, a ultraviolet ray curing type one is most preferably used likewise in the ink as the resin liquid 3. Thus, at the time of using, the resin liquid 3 can be cured instantaneously by irradiation with an ultraviolet ray, thereby preventing the resin liquid 3 from dropping outside.
