Title: Gas atmizing apparatus for manufacturing metal powder
Inventor: IDE HIDETERU
IPC: B22F9/08
Filed: 1989-11-06
Abstract: PURPOSE:To catch and remove generated bulk and to prevent lowering of the productivity by arranging a screening net traversely crossing an atomizing chamber at lower part of the atomizing chamber where metal powder is formed by blowing atomizing gas to molten metal stream. CONSTITUTION:In the vacuum melting furnace 4, the molten metal 10 obtd. by melting metal raw material with a melting furnace body 5 is introduced into a tundish 6 and caused to flow down to top part of the atomizing chamber 2 from a nozzle at the lower part thereof. The atomizing gas of Ar, etc., is blown to this flowing-down molten metal 10 from the atomizing nozzle 7. By this method, the molten metal 10 is pulverized and rapidly cooled to form the metal powder 9 and discharge this into a vassel 8 through piping 12 at the lower part. In the above gas atomizing apparatus for manufacturing the metal powder, at the lower part in the above atomizing chamber 2, the screening net 1 is arranged traversely crossing this. By this method, in the process for dropping the bulk generated with blowing-up, this is caught and removed and the lowering of productivity caused by closing the piping 12 with the bulk, is prevented.

Title: Heat storage and release method
Inventor: YABE MASAYOSHI
IPC: C09K5/06
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a heat storage and release method whereby the m. p. or heat storage capacity of a heat storage material compsn. does not change even when the compsn. is used repeatedly and whereby the compsn. can be used safely and stably for a long term by using a heat storage material compsn. which mainly comprises trimethylolethane and erythritol and is contained in a tightly sealed container. SOLUTION: Usually, the mixing ratio of trimethylolethane to erythritol is (80:20)-(50:50). The heat storage material compsn. may further contain up to about 50 wt.% other heat storage material (e.g. paraffin) or supercooling preventive (e.g. a phosphate) as far as the characteristics of the compsn. are not damaged. The phase transition point of the compsn. having the max. latent heat is set at 75-95 deg.C. Pref., the tightly sealed container has a means for absorbing the vol. change and/or the pressure change of the contents. The container is made e.g. of stainless steel, glass, or crosslinked polypropylene. Since the compsn. is gradually degraded under heating at high temp. in the presence of oxygen. the amt. of oxygen is limited to 15 wt.% or lower.

Title: 1-bit inversion error processing system
Inventor: KOYATA SHIGENORI
IPC: G06F12/16
Filed: 1987-11-18
Abstract: PURPOSE:To prevent the frequent generation of one-bit error software reports by counting up a number when an address at the time of generating an error coincides with the preceding error generating address, and only when the count value reaches a prescribed value, reporting the state. CONSTITUTION:When an one-bit error is generated by reading operation from a master device 10, a memory device 12 logs an error generating address, corrects an one-bit inversion error and outputs the corrected result to the device 10. Then, the device 12 compares the an error generating address An with the preceding error generating address An-1 after logging, and when both the generating addresses coincide with each other, counts up the contents of an error generating counter C by '+1'. When the value of the counter C reaches a previously determined prescribed value N, the device 12 reports error generation to the device 10. When the generated addresses are different from each other, the contents of the counter C are cleared and the error generation is reported to the device 10. Consequently, the frequent generation of reports can be reduced and correction timing can be applied by the writing access from the master device, so that the report can also be omitted.

Title: Sense amplifier driver
Inventor: MATSUMOTO AKIHIRO
IPC: G11C11/419
Filed: 1988-11-17
Abstract: PURPOSE:To reduce malfunction due to noise by composing a sense amplifier driver of a bipolar transistor for drive, which is connected to an MOS transistor to be operated by a signal, and a resistor inserted to a collector. CONSTITUTION:When a sense amplifier 16 is activated, an 'H' is inputted to a terminal 14 and MOS transistors 2 and 3 are turned off. Then, the 'H' is inputted from a terminal 13 and an 'L' is inputted from a terminal 15. After that, MOS transistors 1 and 4 are changed from a turning-off condition to a turning-on condition. At such a time, the MOS transistors 1 and 4 start to flow a drain current and bipolar transistors 5 and 6 for drive are controlled by the current. Namely, the drain current goes to the base current of the bipolar transistors 5 and 6 for drive. Resistors 7 and 9 are respectively inserted to the collectors of these bipolar transistors 5 and 6 and the respective transistors 5 and 6 execute saturation operation by these resistors 7 and 9. Thus, the malfunction due to the noise can be reduced.

Title: Production of thick steel plate excellent in low temperature toughness
Inventor: HASEGAWA TOSHINAGA
IPC: C21D8/02
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain good low temp. toughness in a steel plate at a low cost by subjecting a slab before two phase region heating-two phase region rolling stages to prescribed heating and cooling. SOLUTION: It is required that the structure of a slab is refined before two phase region heating-two phase region rolling stages for super-grain refining. For this purpose, at first, the slab is heated to the AC3 transformation point to 1050 deg.C. In this way, the coarse solidified structure is eliminated, and also, the refining of the structure after cooling is facilitated. Next, it is cooled to <=500 deg.C at a cooling rate of 0.5 to 20 deg.C/s without executing rolling. In the case the cooling rate at the time of cooling transformation is too slow, coarse ferrite αis produced however much austenite γ may be refined, therefore, the refining of the structure cannot be attained. But, in the case the cooling rate increases to occur bainitic transformation, the refining of the structure tends to be saturated one.
