Abstract: PROBLEM TO BE SOLVED: To provide a proper liquid break at a sensitized part for prompt level-detection by applying a sensor sensitized part of a sensor head with a water-repellent finish. SOLUTION: A sensor sensitized part 6 of a sensor head 5 is applied with a water-repellent finish. The water-repellent finish includes, for example, applying or baking of a fluorinated resin, and in the present case, it is a coating by baking of PTFE(polytetrafluoroethylene) 7 of a thickness 50-70 μm. Thus, the liquid break action at the sensor sensitized part 6 of the sensor head 5 becomes definite in change of a level sensor from in the liquid to a gaseous phase, resulting in prompt detection of liquid level.

Abstract: PROBLEM TO BE SOLVED: To provide a compact and inexpensive inverse F-type antenna using a waveguide as an element by sharing one antenna with two kinds of antennas. SOLUTION: A coaxial connector 10 is constituted of a central conductor 21, outer conductor 22, and dielectric 30. The outer conductor 22 is connected with an element 1 of a waveguide, the central conductor 21 is extended to the central part of the waveguide, and a coaxial converter can be constituted. A coaxial connector 11 is constituted of a central conductor 23, outside conductor 2, and dielectric 32. The central conductor 23 is connected with the outer conductor 22 of the coaxial connector 10. Consequently, the outer conductor 22 can be obtained as an outer conductor for the coaxial connector 10, and a central conductor for the coaxial connector 11. The outer conductor 22 as the central conductor is insulated from the outer conductor 2 by the dielectric 31, so that the element 1 can be excited as an inverted F-type antenna.

Abstract: PROBLEM TO BE SOLVED: To easily manufacture a approximate spherical framed structural body and realize a smooth spherical approximation by continuously combining a plurality of beam materials having the same length in a quadrangular form so that the connecting point has a prescribed radius of curvature. SOLUTION: Four beam materials 10 of the same length having a prescribed length dimension are combined in a quadrangular frame form, for example, diamond form. When three frames of the quadrangularly combined beam materials 10 are continued radially, for example, a spherical surface is approximated by their connecting points A, B, D, C, D, E, F, and G. When the quadraugularly combined beam materials 10 are continuously in a quadrangularly form in the same manner to extend the approximate area, a spherical surface of a semi-spherical form having a curvature radius R or more is approximated. According to this, an approximate spherical framed structural body can be easily manufactured, and a smooth spherical approximation can be realized.

Abstract: PROBLEM TO BE SOLVED: To make the throughput of an isochronous command such as a teleoperation command by dividing the processing of an isochronous command signal that is received in an equal interval into plural steps, accumulating a competitive internal processing request in a buffer and processing it in a gap between isochronous command processing. SOLUTION: A command preprocessing circuit 1b accumulates an isochronous command signal 4 that is sent from the earth to an artificial satellite through an interrupt signal 22 and detects Tail sequence. A buffer 2 temporarily accumulates an internal processing request 5 such as an HK command and an HK telemetry. A signal processing circuit 3c divides the processing of an isochronous command signal into plural steps and executes each step processing and internal processing with the signal 22. A timer circuit 21 makes time from Tail sequence detection till distribution start of output data to a user's device constant by setting an interrupt interval so that each step processing and competitive internal processing may be finished within the interrupt interval.

Abstract: PROBLEM TO BE SOLVED: To provide a flow rate measuring device capable of obtaining the velocity of flow with high accuracy regardless of the greatness or smallness of the velocity of flow, without incurring halation or the superimposition of pathlines due to long-term exposure. SOLUTION: Through the use of a color CCD camera 9 and a tri-color light source 4, the color dynamic images of a tracer 3 in a fluid 1 are continuously obtained. The emission timing of the light sources 5, 6, and 7 of each color of the tri-color light source 4 is adjusted so as to obtain a starting-point image at the time immediately after the starting of exposure, an endpoint image immediately before completion, and pathline images connecting them. Tracer images are connected with each other in proper time sequence, and the marked tracer 3 is tracked. As the long travelling range by the tracer 3 can be realized by sequentially superimposing a starting point on an endpoint as necessary from among a plurality of tracer images in which starting points and endpoints are connected by pathline images, it is possible to measure the velocity of flow with high accuracy without incurring halation at low speed, with preventing reduction in the brightness of images at high speed, and without mistaking another tracer for the marked tracer.

Abstract: PROBLEM TO BE SOLVED: To attain the separate and independent output of the USB and LSB signals, to reduce the conversion loss and also to improve the image suppression ratio by adding a variable delay element and a variable coupler for compensation to the upper or lower side band of an image rejection mixer. SOLUTION: A high frequency signal inputted via a high frequency signal terminal 1 is divided into two signals by a 90-degree hybrid coupler 2a with the same amplitude and a 90-degree phase difference. These divided signals are inputted to the mixers 3a and 3b respectively. Then a local oscillation wave inputted via a local oscillation wave terminal 4 is divided into two waves by a power distributor 5 with the same amplitude and the same phase. These divided waves are inputted to the mixers 3a and 3b. Both divided frequency signals and oscillation waves are mixed together by the mixers 3a and 3b in regard to the frequency, and the produced intermediate frequency signals are synthesized by a 90-degree hybrid coupler 2b. Then the USB and LSB signals are primarily outputted to the terminals 6a and 6b respectively and then synthesized by a coupler 7 with the same amplitude and opposite phases.
