Title: Low nitrogen oxide burner
Inventor: KANEHARA NOBUYUKI
IPC: F23D14/02
Filed: 1979-12-25
Abstract: PURPOSE: To accomplish low NOX combustion of a burner suited for use as a domestic combusting apparatus, by forming a primary flame hole section in a pressure  equalizing chamber, and covering the primary flame hole section by a primary  combustion chamber including a secondary flame hole section.  
     CONSTITUTION: Gas ejected from a gas nozzle 5 is drawn into an inlet port 4 of a burner while drawing ambinet air as primary air and mixed with air uniformly while passing through a mixing pipe section 6 and a pressure euqualizing section 7. The mixed gas is equalized the pressure moreover to eject at equal speed from the primary flame hole 8 provided in a primary blaming hole section 8. Flame ignited at a secondary flame section 12 is retracted to the primary flame hole section 9 if the excess air ratio of the primary air is higher than a combustible level, and the primary combustion flame 13 is formed in a primary combustion chamber 10, so that the primary combustion is caused with the primary air alone. Here, since this primary combustion is caused at the region where the content of fuel is too rich, fuel gas is decomposed into gases of H 2 , CO, CH, etc., and these gases are combusted secondarily at the secondary flame hole section 12 together with ambient air.

Title: Molten metal production of high chromium alloy steel
Inventor: OOGAHIRA KAZUO
IPC: C21C5/28
Filed: 1979-12-28
Abstract: PURPOSE:To reasonably perform the molten metal production of a high Cr alloy steel by a method wherein the processes for de-Si, De-P, and de-S of hot metal and slag discharging are done in one operation, and the use of Ar and CaO is decreased in the bottom-blown decarburization process. CONSTITUTION:A one-time treatment is performed for the processes of de-Si, de-P, and de-S of hot metal, by bcombining a Na2CO3-based flux and an oxidizing agent such as O2 or iron oxide. In this process, P is reduced below 0.015% and S below 0.015%, and the slag discharge process is done in one operation to reduce the loss in heat and yield. Furthermore, a converter having a bottom blown function is used to perform more effective de-C operation so as to reduce the use of Ar and to control the slag basicity to 1.4=CaO/SiO2 1.7 at the finishing decarburization process. The content of MgO is controlled high for low basicity and low for high basicity, in the range of 5-15%; this reduces the amount of slag, the concentration of chromium oxide in slag, and therefore Cr loss in slag, thereby effecting a reasonable high-Cr alloy steel production.

Title: Disc cartridge and recording and/or reproducing apparatus employing the disc cartridge
Inventor: TEJIMA KEISUKE
IPC: G11B23/03
Filed: 1994-06-29
Abstract: PURPOSE:To insert a disc cartridge into a recording/reproducing apparatus smoothly by a method wherein a trench is not formed in a cartridge main part but, instead, the shapes of the cross-sections of both the side walls of the cartridge main part which are parallel with a cartridge insertion direction and face each other are different from each other. CONSTITUTION:In order to prevent a disc cartridge having a shutter 12 from being inserted into a recording/reproducing apparatus with incorrect orientation, the shapes of the cross-sections of both the side walls of the cartridge which are parallel with a cartridge insertion direction and face each other are different from each other. If the disc cartridge is inserted into a disc cartridge insertion inlet 21 with correct orientation, the cartridge can be held by a cartridge holder provided in the recording/reproducing apparatus. On the other hand, if the cartridge is inserted upside down, the cartridge main part 4 hits the opening circumference of the disc cartridge insertion inlet 21 and the cartridge can not be inserted further, so that the misinsertion can be avoided.

Abstract: PROBLEM TO BE SOLVED: To satisfy wafer process deviation only in one side to realize a high speed design by selecting a plurality of delay buses in accordance with an output of a transistor capacity determining transistor provided on a wafer to relatively adjust a timing between a clock signal and a data signal. SOLUTION: A capacity determining N-MOS transistor 301 supplies a comparator 500 via a resistive element 312 with a voltage corresponding to a transistor capacity on a wafer based on a current capacity in accordance with finishing conditions of a wafer process. The comparator 500 performs comparison with respect to a supply voltage from a constant current generating circuit 400 which is independent of the finishing conditions of the wafer process. For example, when deviations of the wafer process exist in a high speed side, an 'H' level is transmitted to a selector 700. In this case, the selector 700 selects a selection line having a large delay time among a delay element 601 composed of a plurality of selection lines having different delay time.

A distance to each photodetector on the photodetector trains 33, 34 from the optical axes 4A, 4B is equal, respectively, and a luminous flux generated from an object to be photographed is made incident uniformly. Also, by a difference of an optical path length, photodetecting surfaces of the first and the second photodetector trains 33, 34 pinch a position which is optically conjugate to a photographing surface of a film 21, and a position of this focusing detecting device 26 is determined so as to be positioned at the front and rear parts separated by an optically equal distance to each other from this expected focal plane 35. That is to say, when a light passing through an image forming lens 1 forms an image on the expected focal plane 35, a distinction of an image to two photodetector trains 33, 34 coincides, and the photodetecting quantity of both the photodetector trains becomes equal. According to such a constitution, a focusing detection by a horizontally shifted state of an image and a distinction of the image can be executed exactly.
