Title: Production of silicon nitride
Inventor: ISHII TOSHIJI
IPC: C01B21/068
Filed: 1986-12-26
Abstract: PURPOSE:To produce the title Si3N4 having a remarkably reduced content of carbon, by heating a mixture of silica and carbon in a gaseous mixture of NH3 and N2 at the time of producing Si3N4 by a silica reduction method. CONSTITUTION:A mixture of silica and carbon (with or without seed powder) is heated in a gaseous mixture of NH3 and N2. Consequently, the carbon content in the Si3N4 powder can be remarkably reduced. Since gaseous NH3 is added to gaseous N2 and mixed, the gaseous CO generated in the reaction process is allowed to react with NH3 and removed. Besides, the C generated in the synthesis process reacts with NH3 and is removed. Since the CO and C are removed as gaseous CH4 and gaseous C2H2, the inclusion of C in the Si3N4 powder to be synthesized is prevented.

Abstract: PURPOSE:To enable a plurality of gas-fired water heaters to be divided into two groups which can be operated sequentially, by providing, between a solenoid-driven ON-OFF valve and a driving power supply, a pressure difference detection switch which connects the valve and the power supply to each other when water pressure becomes lower on the hot water supply side than on the feed water supply side and the pressure difference exceeds a set pressure. CONSTITUTION:When hot water is supplied by a gas-fired water heater 10, feed water supplied to the water heater 10 receives resistance while passing through the interior of the water heater 10, for example, through a heat exchanger 16. Therefore, water pressure becomes lower on the side of a hot water supply pipe 50 than on the side of a feed water supply pipe 40. The pressure difference increases as the opening of a faucet J is enlarged to increase the flow rate of water through the water heater 10. When the pressure difference reaches a predetermined level, a pressure difference detection switch 71 is turned ON, whereby a driving current is passed from a driving power supply 80 to a solenoid-driven ON-OFF valve 61, whereby the valve 61 is opened, and feed water is supplied also to a gas-fired water heater 20. As a result, hot water is supplied by operating the two water heaters 10, 20.

Title: Method for growing crystal under microgravity
Inventor: SUZUKI YUICHI
IPC: C30B19/00
Filed: 1988-12-07
Abstract: PURPOSE:To achieve the crystal growth which requires a long period of time under microgravity on the ground without going to the universe by creating a microgravity state by free falling, bringing a supersaturated soln. into contact with a substrate and executing the crystal growth repeatedly. CONSTITUTION:The substrate is brought into contact with the supersaturated soln. within the slight time  T of 5 to 10 seconds when the microgravity state can be attained to allow the crystal to grow. The contact is interrupted before the end of the free falling. The contact is interrupted to prevent the crystal growth from taking place in the high gravity (for example, about 20G) state at the time of braking to stop the device from the free falling state and under the ordinary gravity (1G state) to lift the device again and to reset the device. The supersaturated soln. is formed and is brought into contact with the substrate to create the state of depositing the crystal just before the free falling. The falling is repeated, for example, several hundreds to several thousands times by which the uniform crystal having about the same size as the size of the bulk crystal obtainable in the universe and the high quality is grown on the substrate.
