Title: Method of converting wave energy by use of hydraulic turbine
Inventor: TSUBOTA JIYUNJIROU
IPC: F03B13/20
Filed: 1979-09-03
Abstract: PURPOSE: To take out the energy efficiently from the waves caused on water surface, by dividing the inner space in a box into two air-tight pressurizing chambers, forming liquid reserving tanks at an upper portion in said box, and communicating these tanks with each other via the turbine.  
     CONSTITUTION: The inner space in the box 1 is divided into two air-tight pressurizing chambers 3, 4 by a central partition 2. At the upper portion in the box 1, there areformed tanks 5, 6 for reserving liquid therein. These two tanks 5, 6 are communicated with each other via the turbine 11. With such an arrangement, when waves are formed on the water surface, the internal pressures in the chambers 3, 4 are changed alternately by the waves caused on the water surface, which causes flow of liquid in tanks 5, 6 through conduits 9, 10 and drives the turbine 11. Thus, it is enabled to take out energy efficiently from waves caused on the water surface.

Filed: 1982-06-29
Abstract: PURPOSE:To control exactly the transmission of incident light by a polarizing direction, by holding liquid crystals having a lower refractive index than that of a substrate between transparent substrates subjected to a parallel orientation treatment, and making linear polarized light incident to a cell at a specific angle. CONSTITUTION:Liquid crystals 3 subjected to a parallel orientation treatment of no<ng and ne<ng are held between transparent substrates 1, 2 having a refractive index ng. If the transmission axial direction of a polarizing plate 4 and the molecular axial direction (oriented direction) of liquid crystals 3 are parallel, the refractive index of the liquid crystal 3 to incident light 5 becomes ne, and if these directons are vertical to each other, the refractive index of the liquid crystals 3 to the incident light 5 becomes no. An incident angle theta is set as an inequality. By making the axial direction of transmission of the polarizing plate 4 at this time parallel or vertical to the liquid crystals 3, the refractive index of a liquid crystal layer is made to no or ne, and the incident light 5 is transmitted to the interface between the liquid crystal and the substrate or fully reflected at said interface.

IPC: F16F9/14
Filed: 1994-05-26
Abstract: PURPOSE: To restrict pressure lowering below the atmospheric pressure on both sides of a blade and to simplify the structure by providing a closing valve means between a compensation chamber and each space in order to prevent the flow from the compensation chamber to each space when the pressure in the compensation chamber and each space within a liquid chamber exceeds the atmospheric pressure. CONSTITUTION: When a rotor 18 is driven by the torque added to a rotating shaft 20, the pressure of the space whose volume is reduced by the rotation of the rotor of two spaces 16a, 16b increases. According to this, a fluid is pushed into the other space through a passage 34 at a flow rate controlled by a regulating valve. A valve 54 for generally sealing a compensation chamber 52 from the passage 34 is formed of a spring plate which separates from a port 56 and bends when the pressure of the area adjacent to the passage 34 is less than the pressure of the compensation chamber 52. Since the fluid in the compensation chamber 52 is kept substantially at the atmospheric pressure by a diaphragm 50, the connecting port 56 is opened to suck the fluid into a fluid chamber 16. Thus, the formation of a cavity can be prevented in every space of the fluid chamber 16.

Accordingly, even if it is discharged completely, it is possible to perform the recharge in an extremely short time. Moreover, it does not require maintenance such as the confirmation of an electrolyte, exchange, etc., as a battery. Furthermore, since the capacitance in the same volume is very large, it is possible to extend the preservation time of the output time Vo at power failure without enlarging the device.
