Title: Marine vessel
Inventor: KIKUCHI NAOMI
IPC: B63B1/20
Filed: 1988-09-02
Abstract: PURPOSE:To facilitate the planing of a marine vessel and to prevent the influence of a wave generated at a contact portion between surface of the water and a ship's bottom by providing plural bottom plates upward tilted on their bow sides from the bow to the stern, and arranging a propulsion device at a position nearer to the bow than the center of gravity of a hull to increase water pressure acting on the hull. CONSTITUTION:In the case where marine vessel speed caused by the propulsion force of a screw 18 is relatively slow, the first-the third bottom plates 6-8 are located below the surface of the water, and when a marine vessel is slowby accelerated to make the water strike against a hull, upward strong force is given to each of the bottom plates 6-8 to make most of the marine vessel rise above the surface of the water. In this case, relatively large wave W is generated at a contact portion between the surface of the water and each of the bottom plates 6-8, but since the bottom plates 6-8 are formed upward against a ship's bottom, a contact area between the wave W and each of the bottom plates 6-8 becomes narrower to reduce resistance caused by the wave W. Next, when the marine vessel is decelerated, a bow 9 gradually lowers to make each of the bottom plates 6-8 sink below the surface of the water, and air gathering in a corner 15 is therefore exhausted outside from a through hole 16. Thus the air contained in the ship's bottom can not increase the resistance against the hull.

Title: Heat exchanger
Inventor: SOFUE TSUTOMU
IPC: F28F1/32
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To control overheating of other water pipes when a part of water pipes are in use by arranging fins so that the heat absorption of a tubular part on the upstream side is reduced and the heat absorption of a tubular part on the downstream side is increased compared with the case where the fins are continuously provided on the tubular part on the upstream side and the tubular part on the downstream side. SOLUTION: The heat absorption in each of first, second, third, sixth, seventh and eighth straight pipes (41, 42, 43, 46, 47, 48) is reduced and the heat absorption in each of fourth, fifth, ninth, and tenth straight pipes (44, 45, 49, 50) is increased by reducing the number of lower half parts 32, 32 continuously provided on the first, second, third, sixth, seventh and eighth straight pipes (41, 42, 43, 46, 47, 48) is smaller than the sum of the number of upper half parts 31, 31. Thus, superheating of the sixth to eighth straight pipes (46, 47, 48) of a second water pipe 4b which is on the non-use side while hot water is fed, and overheating of the first to third straight pipes (41, 42, 43) of a first water pipe 4a which is on the non-use side during the reheating operation, are controlled. The durability of a heat exchanger 1a is improved thereby.

Filed: 1992-08-20
Abstract: PURPOSE:To make an output level constant regardless of channels by automatically offsetting the difference of the levels between output channels even when it is generated by the frequency characteristics of a frequency converter, an amplifier and a filter circuit. CONSTITUTION:The output levels of the respective channels of the output of the filter circuit 5 are measured and the lowest level of the channel is defined as a reference value. Then, at the other channels, the difference of the level with the reference value is calculated and stored in a memory 10 as a correction value. Then, at the time of controlling a variable attenuator 8, a CPU 9 reads the correction value corresponding to the output channel from the memory 10, turns it to a fixed value, supplies it to the attenuator 8 and controls attenuation amount. Thus, the difference of the levels between the output channels is offset and the output level at an output terminal 7 is fixed at all times.

Filed: 1985-10-07
Abstract: PURPOSE:To make invariably accurate focus adjustment and to confirm lighting effect by shortening intermittent lighting intervals of a flash discharge tube according to the drop in the charging level of a capacitor. CONSTITUTION:A main capacitor 5 is charged with the output of a source voltage 1 through a DC/DC converter 3 and a diode 4 and its divided voltage is applied to a signal generating circuit 8 through a line (a). When a switch 14 is closed and a monostable multivibrator 15 operates, the higher the charging voltage of C5 becomes, the longer the period of output pulses from the circuit 8 becomes and the lower said voltage becomes the shorter said period becomes. The discharging of the C5 allows the flash discharge tube 31 to emit light and when the charging voltage of the C5 drops, the light is emitted intermittently at short intervals. When a synchronous contact 22 is made, on the other hand, the output pulse of a generating circuit 23 controls a main SCR28 to operate a trigger circuit, so that the discharge tube 31 begins to emit light.

Filed: 1988-09-07
Abstract: PURPOSE:To improve workability in the time of testing at a pressure not less than a preset value by providing a line opening and closing means in a bypass line connecting a high pressure side to communicate with a low pressure side. CONSTITUTION:In the case of a safety valve, when a test is performed for pressure resistance and air-tightness, first a low pressure port 13 is closely sealed by a closing plate 10, and a flow of fluid is disconnected. Next, a plug 15 is opened, and a high pressure port 12 communicates with the low pressure port 13 by a bypass line 14. Next, a pressure is increased to the pressure for testing the pressure resistance and the air-tightness. By the method thus obtained, the safety valve eliminates a pressure difference between the high pressure port 12 and the low pressure port 13, and a valve unit 3 is prevented from generating lifting force by the differential pressure. Thus eliminating the necessity for pressing a valve rod 4 by a gag bolt 11 as in the past, workability in the time of testing can be improved by enabling damage or the like to be prevented by adjusting the pressing force of the valve unit 3 and by excessively pressing it.
