Title: Melting method of low phosphorus steel in oxygen top blowing steel making method
Inventor: OOGAHIRA KAZUO
IPC: C21C5/34
Filed: 1979-08-02
Abstract: PURPOSE:To make possible the production of low phosphorus steel with ease by blowing oxygen while blowing an inert gas through the furnace bottom at the time of performing iron making refining by the use of high basic molten slag with an oxygen top blowing converter provided with a bottom blowing function. CONSTITUTION:In making low phosphorus steel of <=0.010% P with a converter by using low phosphorus iron of 0.080-0.150% P as raw material, slag of >=2.5 basicity is used. In addition, the molten metal is agitated by blowing an inert gas of Ar or the like through the bottom nozzle of the converter at a rate of 5-50Nm<3>/Hr per ton of molten steel to improve the contact between the molten metal and the molten slag. Also, oxygen blowing is performed by using an oxygen gas of >=46Nm<3> per ton of the molten steel. By the oxidation action by this oxygen, FeO is contained at >=12% as Fe in the molten slag, and this coupled with the high basicity of the molten slag accelerate the dephosphorization reaction of the molten steel, thus the low phosphorus steel of <0.010% P is easily produced.

Title: Centrifugal dehydrator
Inventor: KAWAGUCHI TOMOYA
IPC: D06F49/04
Filed: 1995-03-29
Abstract: PURPOSE: To avoid the generation of abnormal vibration even if clothing housed in the drum of a centrifugal dehydrator is unevenly distributed and to automatically correct the uneven distribution of the clothing to perform dehydration operation. CONSTITUTION: A motor driving circuit 16 gradually raises the rotational speed of a motor 18 on the basis of the command from a rotational speed control part 104. When the rotational speed reaches a predetermined low rotational speed N1, the drive voltage Va detected by a voltage detector 24 is compared with first predetermined voltage V1 in a judging part 106. In the case of Va>=V1, the uneven distribution of the clothing in a drum 20 is large and, when a rotational speed is increased in this state, the possibility generating abnormal vibration is judged to be high and the rotational speed of the motor 18 is allowed to fall to urge the movement of the clothing in the drum 20 to perform eccentric load correcting operation for correcting the uneven distribution of the clothing.  At this time, operation wherein right-handed rotation and left- handed rotation are combined is performed at a low rotational speed of a degree performing the washing of clothing to disperse the clothing.

Title: Aluminum electrolytic capacitor
Inventor: YAMADA HIDEMI
IPC: H01G9/04
Filed: 1990-04-14
Abstract: PURPOSE:To obtain an aluminum electrolytic capacitor having an excellent over-voltage-resisting property and a high safety by winding anode and cathode foils with the starting end of the anode foil preceding that of the cathode foil in the direction of the center of the winding. CONSTITUTION:An anode foil 1 is inserted into separators 3 and 4 and a cathode foil 2 is positioned on the separator 3. Then, the foils 1 and 2 are wound with the anode foil 1 preceding the cathode foil 2 by a precedence distance 'a' (in this case, 4cm). Since the foils are wound with the starting end 1a of the anode foil 1 preceding that of the cathode foil 2, the core of the winding can stand the stress caused by the swelling of the separators. As a result, a distance between electrodes can be kept uniform around the core of the winding, which brings about a good over-voltage-resisting property.

Abstract: PURPOSE:To improve photodetection efficiency by forming a curved surface mirror, which has one focal point at the center of curvature, on an elliptic reflective surface in a focusing block that has the elliptic reflective surface of a transparent body and photodetects light, emitted from one focus, at the other focus. CONSTITUTION:An elliptic pole is formed of a transparent body and the 1st reflector 13 is formed on its elliptic pole surface 13a to constitute focusing block 4. Once smoke enters smoke sensitive area 10, primary light emitted from light emitted by light emission element 5 scatters in any direction and light scattering at right angles to focal axis 14 is all photodetected. However, part of scattering light C1, after being reflected by elliptic pole surface 13a, strikes cylinder hole 15 in smoke sensitive area 10 in process of advancing to the other focal axis 19 and is refracted by its boundary surface, so that light C2 will never focus on the other focal axis 19. For the purpose, column surface 21 which has focal axis 14 agreeing with the center of curvature is formed in elliptic pole surface 13a where reflected light C2 strikes cylinder hole 15 (at opening angle theta), so that the above-mentioned reflected light C2' penetrates through focal axis 14 by focusing.
