Title: Apparatus for locating trouble point of power distributing system
Inventor: URANO FUMIHIRO
IPC: G01R31/08
Filed: 1986-06-20
Abstract: PURPOSE:To locate a trouble point even when insulation is restored, by applying two kinds of pulse voltages different in a wave form to a power distribution line and calculating the distance up to a trouble point from the point of time when the wave forms of the voltages applied begin to drop discontinuously. CONSTITUTION:A pulse generating means 10 applies two kinds of pulse like voltages different in a wave form to a power distribution line 4. A voltage wave form measuring means 11 measures the wave forms of the voltages applied to the power distribution line 4 from the means 10. The voltages applied to the power distribution line 4 propagate while the peak values and boosting rates thereof are reduced at each branch point but reaches a trouble point after a time DELTAT and, when rise to predetermined voltage at the trouble point, said trouble point again generates dielectric breakdown and pulse like voltages drop discontinuously. Since this time DELTAT is the time required before pulse voltages reach the trouble point from the applying point thereof, when the time DELTAT is calculated, the distance from the applying point to the trouble point can be calculated. By this method, even when the insulation of the trouble point is restored, location can be performed and the position of the trouble point can be located without being troubled by the wave form of a complicated reflected wave.

Title: Heat exchanger
Inventor: KOBAYASHI SHIROU
IPC: F24H1/10
Filed: 1982-08-23
Abstract: PURPOSE:To prevent the generation of an after-boiling phenomenon and noises and also of drain on the front flow side of circulating water by a method wherein a heat absorbing pipe of the fin type heat exchanger is made gradually smaller in diameter from the front flow side of the circulating water and heat absorbing fins of the heat absorbing pipe located at the side part of the front flow of a combustion gas are made gradually shorter in length. CONSTITUTION:The diameter of the heat absorbing pipe 1 is made gradually shorter as shown by d1, d2, d3 and d4 as the pipe extends from the front flow side to the rear flow side of the circulating water and lengths l1, l2, l3 and l4 of the heat absorbing fins 2 located below the heat absorbing pipe 1 are made gradually shorter. The distance of heat transfer of the combustion gas flow A under the heat absorbing fins 2 with respect to the heat absorbing pipe 1 is larger on the front flow side of the circulating water so that the temperature of the gas is kept high without dropping below the dew point of the gas to thereby prevent the generation of drain. Further, the quantity of the water stored in the heat absorbing pipe 1 at the time of suspension of a hot water supply is larger on the front flow side than on the rear flow side and the temperature of the water is considerably low so that the rise in temperature due to the maintenance of the heat exchanger is not so high and so the after-boiling phenomenon scarecely takes place. Further, as the flow velocity of the circulating water on the rear flow side of the heat absorbing pipe 1 are accelerated on the rear flow side, the overheating and boiling of the water in the heat absorbing pipe 1 are checked by the agitating action of the water, to thereby prevent the generation of noises.

Title: Intake apparatus of two-cycle engine
Inventor: MURAMATSU TATSUHIRO
IPC: F02B27/00
Filed: 1982-08-23
Abstract: PURPOSE:To increase the output in an intermediate revolution range without suppressing the max. output by installing a box-shaped volume which closely envelops an inlet pipe on its outer periphery and drilling a small-diameter hole on the inlet pipe to allow the inside of the pipe and the inside of the volume to communicate each other. CONSTITUTION:When an intake valve is closed, the pressure in an inlet pipe 3 becomes higher than the pressure in a volume 8, so the mixed-gas supplied from a carburetor 2 flows into the sealed space 7 of the volume 8 from a small- diameter hole 9. During suction stroke, the pressure in the volume 8 becomes higher than the pressure in the inlet pipe 3, so that mixed-gas flows into the inlet pipe 3 from the volume 8 and is sucked into a crank chamber together with the mixed-gas supplied from the carburetor 2. Therefore, the intake ratio is improved, and especially the output in the intermediate revolution range in part- throttle state where the charging efficiency tends to decrease is effectively improved, an sharp reduction of torque can be suppress.
