Title: A device for capturing the power of water waves
Inventor: HAYGARTH EDWARD JAMES ANTHONY
IPC: F03B13/18
Filed: 1990-04-11
Abstract: In a floating structure in which a number of flexible airbags 3 are held at a level at which the bottoms of the airbags when they are filled with air at atmospheric pressure are at or about the level of the water on which the structure floats when the water is perfectly calm. The airbags 3 are compressed by waves passing under the structure, against a less flexible superstructure 1 and 2 immediately above them and a system of valves and air lines enables compressed air to be transferred from the compressed airbags to such place or places as it may be stored or used as a source of power. Separate valves and ballast assist the airbags to regain air from the atmosphere and revert, under the force of gravity, to their original shape or thereabouts, as the waves fall from under them. <IMAGE>

Title: Delay circuit
Inventor: ITOH SAKAE
IPC: H03K5/133
Filed: 1991-06-06
Abstract: A clock signal as a reference and operation of a control object to be delayed with respect to the former are both shifted owing to variations of power supply voltage and so on keeping a relative relation therebetween substantially unchanged, delay time of the control object can stably be set even if the power supply voltage and so on are varied. In the circuit described, the input signal A is both delayed at 4 and divided down at 8 and the resultant signal and the input signal applied to a flip-flop 10. The circuit may be adopted for tri-state buffer control at 3, in which case the input signal delay and the tri- state buffer switch-on delay are matched to reduce sensitivity to supply voltage and/or temperature variation. The output Y is delayed by a predetermined time interval with respect to signal B. The delay section 4 may include a number of inverters, usually formed by transistors. The frequency divider 8 which may precede or follow the delay section may include transmission gates and inverters. <IMAGE>
