Title: Method for refining molten iron
Inventor: IKEDA MASABUMI
IPC: C21C1/02
Filed: 1986-09-01
Abstract: PURPOSE:To improve gas venting of slag so as to prevent the generation of foaming and slopping and to permit stabilization of operation and the cost reduction thereof by interposing a high melting point material in a solid state in the slag in the pretreatment stage of a molten iron. CONSTITUTION:The molten iron is tapped from a blast furnace into a molten iron ladle or torpedo car and is subjected to the pretreatment. The high melting point material such as Cr2O3 or MnO2 which hardly forms a low melting point compd. in spite of reaction with a slag forming material such as CaO or SiO2 is charged into the molten iron ladle or torpedo car at this time. The Cr2O3 or MnO2 is interposed in the solid state in the slag. The gas venting of the slag is thereby improved, by which the foaming is suppressed and the slopping is hardly generated. The outflow of the content from the molten iron ladle, etc., is, therefore, obviated and the stabilization of the operation and the cost reduction thereof are attained.

Abstract: PROBLEM TO BE SOLVED: To prevent quarterly cut papers from moving with each other by a method wherein a gripper which grips a printing sheet approximately at a folding line, leaves a deformation which partially penetrates the quarterly cut papers or a scarred part behind. SOLUTION: A gripper 4 having pinching members 6, 7 grips a printing sheet 2 comprising a plurality of quarterly cut papers being inserted each other, which is partially lifted from a printing sheet stack 5 by an attracting device 16, in the vicinity of a folding line. In this case, the free end of the printing sheet 2 is closed by the pinching members 6, 7 and pulled out from a magazine 11. Then, it is opened, and the printing sheet 2 performs a parallel movement based on the folding line because an acceleration force is applied to the quarterly cut papers on the printing sheet 2 when being moved by a carrying rotor 3.  For this reason, in order to prevent the quarterly cut papers from moving downward, the gripper 4, when being closed, is inserted in the printing sheet 2 by sharp teeth being provided on a tool 20 in the folding line region, or a deformation means of an obtuse angle, and the quarterly cut papers are fixed to each other by a burr formation or an intertwining of paper fiber, and a movement between the quarterly cut papers can be prevented from arising.

Title: Solenoid driving gear for compact disk player for vehicle
Inventor: BOKU SHIYOUWA
IPC: G11B17/022
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To operate a latch type solenoid for holding disks with a single compact disk player for vehicles. SOLUTION: The latch type solenoid for holding the compact disk is used for the single compact disk player for vehicles. The insertion of the compact disk into the compact disk player is detected by a sensor or switch 10 and the solenoid is driven not to hold the disk by a microcomputer 20 in accordance with the detection signal. As a result, the latch type solenoid having a positive terminal and a negative terminal has the property of a losing magnetic force at the time of impressing voltage and to exhibit a magnetic force at the time of not impressing the voltage and, therefore, the object to be held is held by the magnetic force when the voltage is not impressed on the latch type solenoid. On the other hand, the magnetic force is lost and the next operation is automatically started when the voltage is impressed on the solenoid.

Title: Ribbon-like or washer-like flux-cored solder
Inventor: YAMADA SEIJI
IPC: B23K35/40
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide the ribbon-like or washer-like flux-cored solder in which the inter-layer separation is prevented and the flux is not irregularly present by rolling the thread solder where the flux is built in a curved state. SOLUTION: The flux-cored solder is twisted to build the flux 5 in the curved state. To apply the twist, a reel is turned in the plane perpendicular to the pushing-out direction when the solder is extruded in a wire-like condition from an extrusion die and wound around the reel. The effect preventing the inter- layer separation is improved by increasing the twisting number so that the twisted thread solder is not cut off, and building the plurality of cores of the flux 5. The twisted thread solder is passed through rolling rolls 4, 4' to form a ribbon-like solder 3', and it is punched to form a washer-like solder 3". Because no flux is irregularly present in the center by building in the plurality of cores of the flux 5, the defectives including separation are greatly reduced, and the workability is improved.
