Title: Method for laying section on bottom of water
Inventor: OTA MASANORI
IPC: B63B35/04
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the underwater weight of a section for decreasing tension and to miniaturize a damping device and rigging on a ship by mounting a buoyant body whose buoyancy decreases along with the depth of water to the section. SOLUTION: In a laying ship 1, a cable 3 on the bottom passes through a braking device 2 and then is lashed along with a buoyant body 4 by a lashing machinery (or lashing worker) 6. The cable 3 on the bottom descends from the water surface 8 along with the buoyant body 4, that has been lashed and lands on a bottom 9 and is laid. The buoyant body 4 (for example, expanded polystyrene) has characteristics, where the buoyancy decreases along with the depth of water as it goes down in water, while it has been lashed by the cable 3 on the bottom. That is, since the water pressure rises along with the depth of water, bubbles included in the expanded polystyrene collapse appropriately and the buoyancy decrease, thus miniaturizing a damping device and rigging on a ship.

Title: Video tape recorder
Inventor: MINAMI NORIAKI
IPC: G11B5/027
Filed: 1985-05-20
Abstract: PURPOSE:To attain the correction of a skew and discontinuous sequence by providing a PAL system VTR with one synchronous signal extracting means and one PLL loop means. CONSTITUTION:A horizontal synchronous signal included in a reproduced luminance signal is outputted from a generating circuit 11, and inputted to a phase comparator 12. When the skew is detected, a switch 40 is switched to a contact (c), and the phase comparator 12 phase-compares the horizontal synchronous signal of the generating circuit 11 and the output signal of an FF 36. Then an FF 39 compares the phase of the output signal of an FF 38 with that of an error signal outputted from an amplifier 31, that is, the phase of the burst of a reproduced chrominance signal. Since the output signal of the FF 39 comes to H only when the discontinuity of the burst sequence is detected, the burst sequence can be corrected.

Filed: 1985-05-21
Abstract: PURPOSE:To make the amplitude of a sawtooth wave constant regardless of the frequency of a synchronizing signal by detecting the duty ratio of a sawtooth wave generating circuit and feeding back the detection output of the duty ratio so as to vary the charging current of an integration circuit of the sawtooth wave generating circuit. CONSTITUTION:The output of an operational amplifier 10 is integrated by the integration circuit comprising a resistor 15 and a capacitor 16. Since the high level voltage of an operational amplifier 10 is 2Vr, when the duty ratio of the output of the operational amplifier 10 is 50%, the integration level becomes the voltage Vr. An output voltage -Vc of the amplifier 17 is at a level lower than the voltage -Vr fed to an operational amplifier 1. When an output voltage -Vc of the operational amplifier 17 rises, the potential difference with the voltage -Vr fed to the operational amplifier 1 is small, a current i1 flowing via a resistor 21 is decreased and the charging current flowing to a capacitor 5 is decreased. the charging current flowing to the capacitor 5 is subject to feedback control so as to be equal to the voltage fed to the input terminal and the amplitude of the sawtooth wave outputted from the terminal 8 is made constant.
