Abstract: PURPOSE:To enable a stable sail in all weathers by placing a ship body above the waterline, submerging a submarine hull under the water and coupling both with each other through entrance bodies to adjust the buoyancy by lateral steers provided in the front and rear of said submarine hull. CONSTITUTION:When a submarine hull 1 submerges and sails under the water surface WL-2 and waves W-1 approach said hull 1, the buoyancy of +B in the front of an entrance body 3 is increased, whereas a lateral steer 5' is inclined forward downward to form descending buoyancy -F and maintain constant the depth of the front of the entrance body 3 to the water surface WL-2. Also, when the waves W-2 approach relatively the rear of the entrance body 3, the buoyancy of the rear of entrance body 3 is reduced by -B, whereas the depth of the rear of entrance body 3 to the water surface WL-2 is maintained constant by the action of the floating force +F of lateral steer 5''. Thus, the longitudinal horizontality of a ship 2 is stabilized. In the case of rolling, the lateral steers 5''', 5'''' are operated to set the ship 2 to the horizontal state.

Abstract: PURPOSE:To efficiently produce chito-oligosaccharides having relatively high polymerization degrees at a low cost by controlling a reaction solution to a pH lower than the optimal pH of an enzyme, when chitosan is treated with the enzyme to produce the chito-oligosaccharides. CONSTITUTION:When chitosan is treated with a chitosan-decomposing enzyme to produce chito-oligosaccharides, the reaction solution is set to a pH lower than the optimal pH of the enzyme to selectively obtain the chito- oligosaccharides having high polymerization degrees.

Abstract: PURPOSE:To prevent misfiring of ignition coil under insufficient feeding time due to abrupt increase of engine rotation, by forming such that the difference between the width of position signal to be fed from pickup and the firing position is assured forcefully as the feeding time. CONSTITUTION:A waveform added/multiplied onto L point voltage and S point waveform are performed level comparison by a comparator 14 in an ignitor to define the cross-point as the feeding start position while the waveform added/ multiplied onto S point voltage and L-point voltage waveform are performed level comparison by a comparator 12 to define the cross point as the firing position. Diode 20 will function such that Q-output of flipflop 6 will bring the output of comparator 14 low to control such that the feeding start position will not be later than previous output position signal in the output position signals from pickup 1. Consequently, the feeding start position will delay untill occurrence of position signal at the front side of pickup 1 because of quick acceleration, to assure the feeding time shown by slanted time interval even if the firing position has led to the maximum lead angle position thus to prevent misfiring.
