Abstract: Ruled lines printed on a graph paper g are optically detected by a vertical ruled line reading sensor and a horizontal ruled line reading sensor. Ruled line spacing Dp in a plotter coordinate system P is measured and compared with ruled line spacing Dg in a coordinate system G of a given graph paper, and the correspondence relationship between coordinate system G of the graph paper and coordinate system P of the plotter is determined. When a drawing command is inputted, a a coordinate Zc in the drawing command is treated as coordinate Zg in the coordinate system G of the graph paper, and this coordinate Zg is converted to coordinate Zp in the coordinate system P of the plotter, using the correspondence relationship. The drawing command is then executed with respect to the converted coordinate Zp. As a result, figures or waveforms that match the ruled lines of the graph paper can be drawn. Ordinary graph paper can be used because the ruled lines are read, contributing to ease of use.

Abstract: A damping device includes a plurality of rockets (3) each having a nozzle (4) directed outward and disposed at the four corners on the upper floor of a building structure (1) and a device for sensing an earthquake and operating the rockets. With this arrangement, there can be provided a damping device for a building structure which is applicable not only to new building structures but also to existing building structures and can cope with a sudden exciting force caused by, for example, an earthquake with a vertical shock which has been conventionally impossible to be coped with.

The apparatus further includes a gas jetting nozzle connected to a gas cylinder via a gas control valve, a combustion catalyst, an ignition device, heat drive pump, and check valve. The heat drive pump includes a heating portion having a liquid heating recess. A check valve is disposed in each of the discharge and suction sides of the apparatus. The gas catalyst combustion device has a combustion chamber which accommodates the combustion catalyst, includes the heat drive pump's heating portion, and is made of excellent heat conducting material. An opening portion in the recess formed in the heat drive pump's heating portion is located to face upwards with respect to gravity, and the heat conducting apparatus further includes an operating-liquid circulating closed-circuit.

Abstract: A heat-driven pump includes a fluid suction port defining unit which introduces liquid into a heating chamber. Bubbles are formed by heating liquid introduced through the fluid suction port defining unit into a heating chamber. The bubbles cause fluid in the heating chamber to flow out through condensation means and enter the condensation means whereas the bubbles are prevented from flowing through the fluid suction port defining unit due to capillary phenomenon of the fluid suction port defining unit. The bubbles are eliminated by cooling in the condensation means, and elimination of the bubbles causes fresh liquid is introduced through the fluid suction port defining unit into the heating chamber, thereby successive pumping of the fluid being performed.
