Filed: 1982-05-26
Abstract: PURPOSE:To provide a variable relation between the diameters of shafts, cooling and unformalized quantity of liquid by a method wherein liquid pipes of both main shafts having a hollow chamber and a radiater chamber in a bearing block connected to each other by each of steam pipe and liquid pipe are communicated to each other and either steam pipe or liquid pipe is communicated with the other and either steam pipe or liquid pipe is communicated with the other radiater by a flexible pipe. CONSTITUTION:When a bearing block 4 shows a higher increased temperature than that of another bearing block 41, work liquid in a hollow chamber 7 of the bearing block 4 shows a higher volume of steam, steam pressure and temperature than those of the other work liquid in case of its evaporation, so that a higher evaporation latent heat is taken to perform more cooling and the temperature of the block 4 is prevented from being increased more than that of the other block. Then, the hot steam evaporated in the hollow chamber 7 moves to a radiater 81 through a steam pipe 10, and the liquid condensed there shows a higher temperature than that of the liquid in the radiater 8, and flows into the hollow chamber 71 through a liquid pipe 121, so that the temperature of the block 41 is increased and a difference in the increased temperatures between both bearings is restricted low. Although the amount of liquid in the hollow chamber 71 is increased under repetition of this operation, a part of the liquid is returned back to the hollow chamber 7 through a communication pipe 13 and uniformalized. A span can be made variable in a range of expansion and contraction of flexible pipes 10a, 101a and 13a.

Title: Control method for fixed vessel speed
Inventor: SATOU SHIYOUICHI
IPC: B63H3/10
Filed: 1983-05-25
Abstract: PURPOSE:To minimize fuel consumption at a fixed speed of a vessel by driving a main engine with a rotation number of the engine requiring minimum fuel consumption volume when the speed of the vessel becomes a fixed value. CONSTITUTION:A comparator 1 computes a deviation epsilon from a set speed V0 of the actual vessel speed V. A control volume computing unit 2 computes a pitch volume of a propeller 4 whereby the deviation epsilon becomes zero. A pitch changer 3 changes the pitch of the propeller 4 by the same amount with above pitch volume and this operation is continued till the vessel speed V becomes equal to the set speed V0. When the vessel speed V becomes equal to the set speed V0, the rotation number of the main engine at the minimum fuel consumption volume is obtained. A governor 5 controls the main engine to rotate in the above rotation number. This construction permits the vessel to proceed in a fixed speed with the minimum fuel consumption volume.

IPC: C21D8/06
Filed: 1992-04-10
Abstract: PURPOSE:To obtain a steel wire for reinforcing glass excellent in sealability by subjecting the wire rod of a slab having a specified compsn. to wire drawing, thereafter executing annealing to regulate its strength into specified one and applying electroplating whose b.p. and thickness are specified thereon. CONSTITUTION:Wire rod obtd. by subjecting a slab constituted of, by weight, <=0.02% C, 0.2 to 0.4% Mn, <=0.003% Al and <=1.3 Al/N, and the balance Fe to wire rod rolling is subjected to wire drawing to regulate its size into a prescribed one and is annealed to regulate its final strength into 45 to 51kgf/mm<2>. This steel wire is applied with electroplating of >=1050 deg.C boiling point temp. to regulate its thickness into 2 to 10mum and is thereafter subjected to skinpass wire drawing of 5 to 15%. In the case the amt. of C in the steel is too large, bubbles are easy to generate at the time of glass sealing and its strength increases to deteriorate its netting workability. In the case the amt. of Mn is too large, its strength needlessly increases, and in the case it is too small, its butt resistance weldability deteriorates. In the case the amounts of Al and N are too large, the control of its tensile strength into certain one is made hard and the control of the sealing position is made hard to cause the cracking of glass. In the case the strength of the steel wire is excess, the plane holding of wire gauze is made hard.
