Title: Water-seal method of underwater speed reduction device
Inventor: SOUKAWA YASUJI
IPC: F16J15/40
Filed: 1982-10-09
Abstract: PURPOSE:To make it possible to stably carry out water-lubrication to slidable parts in an underwater speed reduction device with the use of seal-water, by providing a pump used combinedly with a discharge pipe for naturally flowing down water, so that impurities accumulated in the underwater speed reduction unit are forcedly discharged to the outside with the use of pressurized water. CONSTITUTION:Clean water fed into a tank 2 through a ball-tap valve 1, is pressurized by a pump 11 and then, fed to an underwater speed reduction device 6 as a seal water. The seal water leaks in a slight amount from an underwater speed reduction device 6 through gaps in input and output shaft seals 7, 8 to prevent sewage and foreign matters from entering into the underwater speed reduction 6 unit and as well to carry out water lubrication to slidable parts therein. Meanwhile, excess seal-water is returned to the tank 2 through a return pipe 9 after being dust-removed by a strainer 10. If the turbidity of return water is high, a discharge valve 4b is opened to forcedly discharge water staged in the underwater speed reduction unit 6 into a sedimentation basin, and fresh clean water is fed to the device 6 by means of the pump 11. Thereby, impurities are prevented from being accumulated in the underwater speed reduction device 6, thereby the predetermined objects may be accomplished.

Title: Clock control circuit
Inventor: SATO NOBORU
IPC: H03K5/00
Filed: 1988-07-15
Abstract: PURPOSE:To enable a clocked inverter to keep a holding state of an output by switching a clock to another one in case the clock input is not received for a fixed period. CONSTITUTION:In case a clock A is stopped and kept at 'L' for a fixed period, the output of a logic gate (a) is kept at 'L' as long as the clock A is kept 'L'. Thus a counter (b) is never cleared any more and therefore has its output of 'H' when it counts three rises of a clock B. Then a selector (d) selects the clock B. In other words, the clocked inverter (t) can work synchronously with the clock B after holding its output for a period of three cycles with the clock B. As a result, the inverter (t) can keep the holding state of its output and the output I is stabilized.

Title: Correction circuit of reproducing and synchronous signal
Inventor: OBARA NAGAYOSHI
IPC: H04N5/93
Filed: 1984-08-29
Abstract: PURPOSE:To correct a synchronous signal obtained during a high speed reproducing to a synchronous signal during a reproducing at unmagnification speed identically by controlling for delaying a reading speed of a reproducing signal from a frame memory from a writing speed during a rewinding and reproducing CONSTITUTION:A reproducing video signal 100 is inputted into field memories 1, 2. A memory reading and writing control device 5 feeds a writing signals 201, 202 to the memories 1, 2 and the signal 100 is written in the memories at a prescribed timing. The signal 100 written in the memories 1, 2 is read by reading signals 301, 302 outputted from the device 5 at a prescribed timing. In this manner, a reproducing signal obtained during a high speed reproducing is written in a memory once, during a fast feed reproducing, a speed for reading the reproducing signal from the memory is made faster than a writing speed, and during a rewinding reproducing, a speed for reading the reproducing signal from the memory is made more slowly than the writing speed. Therefore, a synchronous signal obtained during a high speed reproducing can be corrected to a synchronous signal during the reproducing at unmagnification speed identically.
