Title: Buffer type gas-blast circuit-breaker
Inventor: KANETAKA YASUHIKO
IPC: H01H33/915
Filed: 1989-03-28
Abstract: PURPOSE:To aim at the axial miniaturization of a breaker by doubly forming the circumferential wall of a buffer cylinder in a concentrical manner, and providing buffer chambers for generating a gas flow running axially while surrounding an insulating nozzle in the circuit opening operation of the breaker. CONSTITUTION:The circumferential walls 7a, 7b of a buffer cylinder 7 are doubly formed in a concentrical manner. In spaces between the two circumferential walls 7a, 7b, there are provided buffer chambers 17, 18 for generating a gas flow 24 running axially while surrounding an insulating nozzle 6 in the circuit opening operation of a breaker. Consequently, at the time of cutting off a current, hot gas liable to disperse between a stationary main contact 2A and a movable main contact 3A can be thrust away backward so that a clean gas atmosphere can be maintained between both contacts. Furthermore, an insulating strength can be applied to a recovery voltage after cutting off the current without widening an insulating space between both contacts. Therefore, the insulating space between both contacts can be reduced, thereby enabling the axial miniaturization of the breaker.

Abstract: PURPOSE: To save energy by arranging air holes in the bottom surface of an air chamber in a prescribed distribution state, and introducing outside air into the gutter bottom to the lower part by a compressor connected to the lower gas chamber part in a belt conveyor traveling in a gas chamber. CONSTITUTION: Air holes 15 are arranged in a regular pattern over the total length of a conveyor in the bottom surface of an air chamber 1 by 2 pieces to 40 pieces per 1 m of the length so that the area related to a belt becomes 1.5 cm<2> to 20 cm<2> per 1 m<2> of the belt surface area to form the gutter part 13 opposed to the lower part 14 of the belt. The air chamber 1 is partitioned into the upper chamber part 17 and the lower chamber part 16 by a partition plate 18 so that the intake side of a compressor 8 is communicated with the lower chamber part 16 and the exhaust side is communicated with the upper chamber part 17. Therefore, outside air is introduced through the gutter bottom 13 from the air holes 15 as an arrow by the compressor 8 so as to form an air film on the under side of the belt lower part to thereby reduce friction as well as to save energy.

The source and drain of a field effect transistor 13 are connected to both the ends of the resistance 12. The gate of this transistor 13 is connected to a control circuit 14. After the smoothing capacitor 5 is charged and no rush current flows in, the control circuit 14 turns OFF the transistor 13. Namely, the circuit 14 shunts the resistance 12 by supplying an ON signal to the transistor 13 preferably a specific period after the voltage of the power source begins to be supplied. Consequently, loss is eliminated.

Title: Production of high-toughness silicon nitride sintered body
Inventor: MITOMO MAMORU
IPC: C04B35/58
Filed: 1989-03-29
Abstract: PURPOSE:To produce the sintered body having high toughness and a uniform structure even when beta-type silicon nitride is used by using beta-type silicon nitride powder having high-temp. stability and having a specified small grain diameter and sintering the powder under specified conditions by gas pressure. CONSTITUTION:The silicon nitride powder consisting essentially of a beta-type and having <=1.5mu average grain size is mixed with a sintering assistant, and the mixture is formed and then sintered at 1800-2100 deg.C in N2 at 2-200atm. In this case, when the average grain size is larger than 1.5mu, the grain of the sintered body is enlarged, large pores remain in the body, and hence the fracture toughness and strength are lowered. In addition, N2 has to be used to prevent the thermal decomposition of silicon nitride, and the pressure is increased as the temp. is elevated.

IPC: B63B27/00
Filed: 1978-06-26
Abstract: PURPOSE: To safely and efficiently ship and land a heavy body, by providing water in a dock to support a ship in a half floating state on pedestals.  
     CONSTITUTION: Water is drained out of the dock 2 so that the ship 1 is put on the pedestals 3. The height of the pedestals 3 is so adjusted that the deck 1' of the ship is placed on almost the same horizontal plane as a ground line GL on the gound 4. Water is introduced into the dock 2 again. The ship 1 is then entered into the dock so that the ship is located in a prescribed position over the pedestals 3 while one side of the ship is placed near a dock wall 2'. The water is thereafter drained out of the dock so that the ship is supported in the half floating state on the pedestals 3. When the deck 2' and the ground line GL are placed on almost the same horizontal plane, a base 6 is secured on the deck 1 and the ground line GL. A carriage 7, whereon the heavy body 8 is put, is moved on the base 6 by an appropriate means. Because the ship 1 is supported in the half floatint state on the pedestals 3, the load upon the pedestals etc. is reduced. The purpose is thus attained.
