Title: Recording and reproducing device of optical disk
Inventor: AOKI KAZUHIRO
IPC: G11B7/0045
Filed: 1992-02-03
Abstract: PURPOSE:To smoothly execute recording and reproducing by using two pieces of optical heads by providing a temporary memory circuit after a signal separating circuit of a recording system and providing a temporary memory circuit before a signal synthesizing circuit of a reproducing system. CONSTITUTION:The video signals separated to two signals by the signal separating circuit 5 are respectively delayed in the signals of the first half and the second half by the temporary memory circuits 6, 7 and are sent to modulating circuits 8, 9. The modulated and delayed signals are sent to laser driving circuits 10, 11 which absorb the lag in the recording start time and trigger the lasers of the optical heads 3, 4 to emit pulse beams, thereby smoothly recording the signals on the optical disk 1. Reproducing circuits 12, 13 binarize the signals recorded on the recording disk 1 and output the signals. The outputs are demodulated respectively by demodulating circuits 14, 15 which absorb the lag of the reproduction start time. These outputs are respectively delayed by the temporary memory circuits 16, 17 and are sent to the signal synthesizing circuit 18, by which the signals are synthesized. The video signals of the same length as the data length of the video signals are thus smoothly reproduced.

Title: Starting of fuel cell power generation system
Inventor: MITANI HISASHI
IPC: H01M8/04
Filed: 1984-01-30
Abstract: PURPOSE:To make it possible to start a power generation system without using a motor or a speed change gear by leading the compressed air discharged from a compressed air feeding device to a modifier through a compressor and by stopping the compressed air feeding device at the time when the temperature of the exhaust gas from the modifier has risen enough to drive a turbine. CONSTITUTION:When starting, valves 16, 17 are closed and valves 18, 22 are opened to operate a blower 21 of a compressed air feeding device 19. Then the compressed air discharged from the blower 21 is fed into the inlet of a compressor 12 and, after passing through this compressor 12, supplied to a modifier 2. Under this condition, the fuel is supplied to the modifier 2 and its temperature is raised. In this way, the temperature of the exhaust gas, which is discharged from the modifier 2 and fed into the inlet of a turbine 13, rises and the turbine 13 starts to rotate. At the time when the temperature of the exhaust gas from the modifier 2 gets higher enough to make the turbine 13 operate by itself, the valve 22 is closed to stop the operation of the compressed air feeding device 19 and the valve 16 is opened so that air is taken in and compressed by the compressor 12.

Abstract: PURPOSE:To obtain a magnetic recording medium provided with both of a high-density recording characteristic and durability by depositing an org. compd. by vacuum evaporation on a thin ferromagnetic metallic film, then coating a lubricating agent by a soln. coating method and drying the coating. CONSTITUTION:The thin ferromagnetic metallic film 3 is formed by an electron beam vapor deposition method, sputtering method, wet plating method, etc., on an under coating layer 2 on, for example, a high-polymer film 1.

Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To easily and speedily input non-standardized alphabets by performing character conversion to inputted specific alphabets to selected non-standardized alphabets. SOLUTION: When it is desired to input (a, e umlaut) on the next line, for example, and a select key is pressed, an input on the next line is prompted so that (a) is first inputted by keying and temporarily fixed. Next, (e umlaut) is to be inputted but first of all, an English character (e) similar to (e umlaut) is inputted by keying. With this operation, (e) is temporarily fixed and 'a' temporarily fixed up to the moment is finally fixed. When a conversion key is pressed in this case, candidates of other languages similar to (e) are read from the non-standardized alphabet memory area of a ROM and displayed while being arranged in line on the final step of a screen. Next, a cursor key is pressed and any target candidate is selected. When the target candidate of (e umlaut) is displayed while being converted and the select key is pressed, the temporarily fixed (e) is turned to (e umlaut) and finally fixed.

Title: Cable cooling method employing heat pipe of heat generating type
Inventor: TAKAOKA MICHIO
IPC: H02G15/20
Filed: 1990-01-29
Abstract: PURPOSE:To reduce running cost for cooling an OF cable by transporting heat produced in a low Curie member section of a heat pipe laid along the OF cable to the generator solvent in an absorption cooling unit thereby producing cooling energy. CONSTITUTION:When the temperature at an HP heating section 4 composed of low Curie point material is lower than Curie point, ferromagnetism is exhibited and heat is produced through AC magnetic field of an OF cable. The heat is fed to solvent in a generator 12 thus heating the solvent and gasifies the refrigerant contained therein. The gasified refrigerant is subjected to condensation and adiabatic expansion through a condenser 13 and an expansion valve 14 thus cooling the heat carrying medium in an evaporator 15 and cooling the OF cable oil through an heat exchanger 20. The refrigerant heated through the evaporator 15 is dissolved into the solvent cooled through an absorber 16 and returned through a heat exchanger 19 to the generator 12. The high temperature solvent from which refrigerant is separated through the generator 12 is heat exchanged through the heat exchanger 19 and fed to the absorber 16. Consequently, the solvent contains a large quantity of refrigerant at all times.

Abstract: PURPOSE:To eliminate false peaks and to take out excellent peak data automatically by detecting the intersection of an intermediate curve and a measured curve, and detecting the maximum value or the minimum value. CONSTITUTION:In a block 5 for the maximum value or the minimum value, the following operation is performed: curves which are plotted based on the position information of an intersection obtained in a block 4 and measured data (a) from a terminal 11 are used; the level and the position of the maximum value are detected when the measured data are higher than the intermediate curve between the intersections; the level and the position of the minimum value are detected when the data are lower than said curve; and the results are taken out through a terminal 12 as peak data (b). Namely, the upper interpolating curve shown by B is obtained fro the block 1. The lower interpolating curve shown by C is obtained from a block 2. In a block 3, the intermediate curve shown by D is computed. The intersection X of the curve D and the curve A is detected with a block 4. The block 5 detects the maximum value or the minimum value of the measured curve between the intersections. The value is specified as only one peak data between the intersections. Therefore, false peaks lower than said peak can be eliminated.
