Title: Power generating method with sea bottom tank
Inventor: URAKAWA SHIGEAKI
IPC: F01K25/10
Filed: 1982-05-21
Abstract: PURPOSE:To smooth electric power by filling sea water and low temperature liquefied gas in turn into a tank at the sea bottom so that the electric power is generated by means of the gas discharged from the tank and the sea water flowing into the tank and this energy is utilized to generate the electric power at a peak time. CONSTITUTION:A liquefied gas feed-out valve 13 is opened to operate a liquefied gas feed-out pump 12 with a sea water valve 7 opened and a vaporized gas discharge valve closed, and the liquid in a low temperature liquefied gas tank 11 is filled into a tank 1. LNG, LPG, etc. with the specific gravity which is smaller than that of the sea water and is varied in response to the temperature of the sea water are used as this low temperature liquefied gas. The gas is heated by the sea water in the tank 1 to be turned into vaporized gas 14 and discharges the sea water 15 into the sea. After the sea water 15 is completely discharged, when the pump 12 is stopped and valves 7, 13 are closed, the pressure in the tank 1 is made equal to the external water pressure. Next, when the valve 3 is opened, the vaporized gas 14 is discharged from the tank 1, thus rotating an expansion turbine 4 and generating the electric power with a generator 5. When the inner pressure of the tank 1 is lowered, the valve 13 is closed and the valve 7 is opened. The sea water rotates a generator 9 with a water turbine 8.

Filed: 1985-04-24
Abstract: PURPOSE:To prevent the connecting part of a guide tube for reactive gas of an electrode from abnormally discharging by connecting the electrode with the tube through a baffle of an insulator which increases the creeping distance of the gas. CONSTITUTION:Reactive gas is fed through a guide tube 11 and a zigzag passage formed of a spacer 15 of a guide tube connector 10 and baffles a16, b17, dispersed from a nozzle plate 9 passed through an electrode 5 into a process chamber 1. Simultaneously, a high frequency voltage is applied by a high frequency power source 6 to the electrode 5 to generate a plasma of the reactive gas between the electrode 5 and a sample base 3 in the chamber 1, and the sample is processed by the active gas in the plasma. At this time, since the high frequency voltage is applied to between the electrode 5 and a joint jig 12 at the connector 10, an abnormal discharge is feasibly generated by the gas, but the spacer 15, the baffles a16, b17 are alternately laminated to increase the length of the gas passage to extend the creeping distance, thereby preventing an abnormal discharge.

Title: Light delay device
Inventor: ASABE TSUTOMU
IPC: H04B10/00
Filed: 1979-07-09
Abstract: PURPOSE: To suppress noise components in an optical transmission system and perform signal transmission of high reliability by the constitution consisting in photocoupling the input side and output side of a light delay element to one output terminal and input terminal, respectively, of a photomixing and branching element.  
     CONSTITUTION: A mixing and branching element 10 performing mixing and branching of light signals has at least two input terminals of optical fibers A, D and two output terminals of optical fibers B, C; the input signal (x) being inputted to the optical fiber A and the output signal (y) being outputted to the optical fiber B. The optical fibers C, D are photocoupled with a delay element 11 and the spreading, etc. of the pulse width of the ouput waveform (y) may be controlled by changing the branching rate of the mixing and branching element 10. Since the pulse width of noise components is usually narrow, taking a delay amount long has the effect of decreasing the peak values of respective impulses of the noise components and averaging them in time, and this enables the communication of high reliability to be realized.

Title: Information recording method utilizing reversible phase change
Inventor: YASUOKA HIROSHI
IPC: G11B11/00
Filed: 1987-04-10
Abstract: PURPOSE:To perform rewriting of information, by using a recording film utilizing reversible phase change and erasing information by projecting high-power light and, after the power of the light is reduced by a period which is shortened when the projecting time for erasing, increasing the power of the light again. CONSTITUTION:When a high-output beam is projected on the already recorded part of a required section and, after a molten state is once passed, erasing (cooling) is performed for a short time while a recording medium is rotated and the intensity of laser light is maintained at its reading-out output level, most of the records in the part are erased. The state of erasing depends upon the ratio of the cooling time to the crystallizing time. The crystallizing time (r) is determined by the characteristic of a recording film and the cooling time is determined by the relative velocity V between the recording medium and the light spot. The radius of the area which can reach the temperature, at which high-speed crystallization takes place, of the recording medium is within a range of ar (0<=a<=1) and the time, during which the temperature becomes lower than the temperature at which high-speed crystallization becomes possible, when the light spot passes at the velocity V is ar/V. Therefore, when the light is turned off or the projecting power of the light is lowered by a time t ar/V, one-beam overwrite with no erasing omission can be carried out.

Filed: 1991-04-18
Abstract: PURPOSE:To suppress leaked power to an adjacent channel and to attain circuit integration when an analog circuit component is in use by executing complex multiplication between a complex envelope representing digital information to be sent and a carrier signal with a digital logic circuit. CONSTITUTION:The complex multiplication in an analog circuit between a complex envelope and a carrier signal is realized by a selection circuit 18 the same digital circuit as the simple digital logic circuit comprising EXOR gates 17a, 17b, 17c. Since the digital circuit is integrated simply and an error factor such as distortion liable to be caused in the analog circuit is not in existence, modulation with high accuracy is implemented. Thus, the leakage to an adjacent channel due to a power spectrum of a spurious component is reduced.

Filed: 1987-04-10
Abstract: PURPOSE:To maintain a stable polishing function for a long period by providing a key operating means for displacing a movable key to a position sunk from the fitting position when an upper surface plate is lowered to fit a rotatable member in a drive member. CONSTITUTION:When compressed air is supplied to a chamber 21 by an electro- magnetic valve 26 before an upper surface plate unit 1 is lowered, a key 8 retreats against the urging force of a spring 10 so that the front end 8a is placed lower than the peripheral surface of bore of a case 3. Then, said unit 1 is lowered by a lift mechanism 4 to fit the case 3 in a drive member 6 and stop the case in a key aligning position. Thereafter, a chamber 21 is opened to the atmosphere by said value 26. Then, the front end 8a of key 8 is protruded by the urging force of spring 10 so that the drive member 6 is slowly rotated to make phase coincide and engageably springs into a key way. Thus the movable key 8 does neither collide with the drive member 6, nor incline, but securely fits so that the upper surface plate 2 is securely driven and the stable polishing function can be maintained for a long period.
