Title: Production of silicon nitride sintered compact
Inventor: ASAI YOSHIHIRO
IPC: C04B35/584
Filed: 1995-02-17
Abstract: PURPOSE: To obtain an Si3 N4 sintered compact ensuring a smooth polished surface by pressureless-sintering a powdery mixture of Si3 N4 with a sintering aid under specified conditions, cooling the resultant temporarily sintered compact having a low open porosity and a high ratio of an α-phase to a β-phase and sintering it under a pressure of gas. CONSTITUTION: Starting materials such as Si3 N4 powder and a sintering aid such as Y2 O3 are mixed and compacted. The resultant compact is pressureless- sintered at about 1,450-1,550 deg.C to form a temporarily sintered compact having <=0.5% open porosity and a ratio of >=0.3 as the ratio of an α-Si3 N4 phase to a β-Si3 N4 phase. This temporarily sintered compact is cooled to room temp. and sintered again under 5kgf/cm<2> pressure of gas in an N2 atmosphere. At this time, the sintering temp. is preferably made higher than the pressureless sintering temp. by about 100 deg.C so as to accelerate sintering. The objective Si3 N4 sintered compact ensuring improved surface smoothness of a polished surface is obtd. even under the relatively low pressure of gas and a large-sized product such as a rolling roll can be produced.

Abstract: PURPOSE:To improve picture quality by forming the mixing ratio of a mixing means by calculating the group of Y-signal high band components at different vertical positions in area where both Y-signal and C-signal exist on horizontal vertical frequency space. CONSTITUTION:A first and a second added signals VL1, VL2 are inputted to a control circuit 23 through horizontal band pass tilters (horizontal BPF) 21,22 respectively. If the center frequencies of the horizontal BPFs 21,22 are set in the high band of horizontal direction frequency, band adjust signals RL1, RL2 come to be the Y-signal components of B-area. In case the band of C-signal is wide, C-signal component exists in B-area as well. Thus, the levels of the signals RL1, RL2 increase. In this way, the signals RL1, RL2 of Y-signal area whose signal levels change according to the band of C-signal are inputted to the control circuit 23. Thus, a color signal C0 is given the processing of less mixing level according to the degree of the mixing of C-signal in Y-signal.

Title: Gas burner
Inventor: KOJIMA HISAO
IPC: F23D14/08
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To cope with widening of a grill and improve carry-over performance by a method wherein a small hole train is formed in a central air-fuel mixture chamber astride two burner port trains formed in two edge parts and a cover plate is arranged above the small hole train with a gap formed therebetween. SOLUTION: Fuel gas is injected through small holes 7 formed in an air-fuel mixture chamber 4. Injected fuel gas resides in a gap between a small hole 7 train and a covering plate 8 and flows over and is ignited by the flames of burner ports train 5 at two edge parts. The ignited flame is propagated from one burner port train 5 to the other burner port train 5 to effect carry- over. Further, since a carry over flame ignited at a gap between the small hole 7 train and the cover plate 8 consumes fuel gas and combustion air in a short time, the flame is fire-extinguished once. When fuel gas gathers, ignition is effected again and ignition and fire extinguishment are repeated until combustion of a gas burner 50 is stopped. Thus, carry-over between the burner port 5 trains is reliably effected by a carry-over part 9 and sufficient coping with widening of a grill is practicable.

In the fuel spacer 23 of a circular cell type, however, the interval between the channel and the outermost peripheral fuel rods can be expanded without winding the space between the band 24 and the channel.  Consequently, a coolant can be efficiently guided to the peripheral fuel rods by the band 24 and a flow tab 21 to improve the thermal tolerance of the fuel rods.

Abstract: PROBLEM TO BE SOLVED: To safely and efficiently treat an org. solvent with a compact equipment without need for an advanced technique. SOLUTION: An org. solvent is diluted in a lidded regulating and diluting tank 1, and the dil. liq. is treated in an aeration tank 2 with activated sludge at 10,000mg/l sludge concn. A gas on the water surface in the regulating and diluting tank 1 is introduced into the aeration tank 2.

Accordingly, since the org. solvent volatilized when diluted is treated in the aeration tank 2, ignition and explosion are not caused, and the working environment is also improved. As the solvent is treated with a concd. sludge, the working efficiency is increased, and the equipment is made compact due to the high-load operation. The sludge concn. is kept high by the dip-type membrane separator, and stable treatment is performed irrespective of the sludge properties.
