Abstract: PURPOSE:To obtain easily ultra-low phosphorus steel in O2 top blown refining by adding slag making agents in the form of powder to molten iron and blowing gases under the bath surface. CONSTITUTION:O2 is injected from three pieces of peripheral nozzles 16 in a nozzle head part A to the molten iron in a converter CV inserted therein with a lance B so that the molten steel is refined by top blowing of O2. Powder of >=1 kind slag making agents such as quicklime, limestone, fluorite, dolomite or the like is carried by a gaseous carrier and is added to the molten iron from the nozzle 15 in the central part.

Title: Printing method of outline font
IPC: G09G5/24
Filed: 1992-03-18
Abstract: PURPOSE:To print high printing-grade characters without complicated correction processing by changing printing speed in the main or sub-scanning direction at the ratio of a printing output to outline front data in the number of character points with a reference and making character-dot spaces in both directions proportional to the number of character points. CONSTITUTION:The same data of forty point characters are provided as outline font data in the number of character points as a reference. When the same data of the forty point characters are coordinate-transformed into ten points, the number of the character points is read first. Speed conversion processing is conducted on the basis of the number of character points assigned. The speed displays speed in the X direction, and indicates speed in the main scanning direction of a printing head at the time of a serial bit printer. When the reference speed of the forty point characters is represented by V, execution printing speed V' is represented by VX1/4. The execution printing speed V' obtained is set, and printing is conducted. Accordingly, when speed in the Y direction, the scanning direction, is kept constant, the spaces of printing dots in the X direction are proportional to the number of character points.

Title: Magnetic recording medium
Inventor: AOYAMA AKIRA
IPC: G11B5/738
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a magnetic recording medium having high coercive force and high S/N by forming a Co-Ni-Cr-Nb magnetic film and specifying the amt. of Nb to <=5at.%. CONSTITUTION:The magnetic recording medium consists of a magnetic film formed on a nonmagnetic substrate with a Cr base film interposed, and the magnetic film consists of Co-Ni-Cr-Nb with the amt. of Nb added by <=5at.%. By adding only a small amt. of Nb, S/N is largely improved. However, if Nb exceeds 5at.%, S/N becomes worse compared to a medium containing no Nb because of signal reduction. Therefore, the amt. of Nb is preferably <=5at.%. Thus, the magnetic characteristics and electromagnetic conversion characteristics of the Co-Ni-Cr-Nb film can be largely improved.
Patent JP-S5072292-A (JP)
IPC: B23H7/10
Filed: 1974-08-14
Abstract: Electroerosion machining (EDM or ECM) is carried out with a minimum of manual intervention. Under control of recorded data an electronic control system utilizing control logic directs the set-up operations as well as the actual machining process. The operations automatically (i.e., without the necessity of manual intervention) include loading and removal of workpieces and electrode material, trueing up of the workpiece (which may be by providing a transformation of the data rather than by adjusting the position of the workpiece), making starting bores, threading the electrode through a starting bore, applying a low melting alloy or other conducting adhesive to cement a core in the process of being cut out by machining, cutting the electrode after completing a starting bore and joining electrode ends after rethreading in a new starting bore. In threading the electrode it may be pushed simply or with the support of a surrounding jet of pressure medium, or it may be pulled by a grapple member.

Title: Power supply protecting circuit
Inventor: OTSUJI MINORU
IPC: G05F1/56
Filed: 1987-04-15
Abstract: PURPOSE:To prevent a power supply circuit from abnormal temp. rise at the time of shorting a load by allowing a Zener diode inserted between the I/O terminals of the titled circuit to fuse a fuse based on a breakdown phenomenon of a power supply circuit due to the shorting of the load. CONSTITUTION:The Zener diode D21 is prepared for equivalently reducing the internal impedance of the power supply circuit at the time of shorting the load and the cathode and anode of the diode D21 are respectively connected to the fuse H21 side of a resistor R21 and the emitter of a TR Q21. Since an operation voltage when the current of the diode D21 is 20mA is 6V when a voltage to be applied to the diode D21 is 5V e.g., the diode D21 is cut off. Since a load resistor R31 is shorted, a high voltage is impressed to the diode D21, so that the diode D21 is conducted at a low impedance and the fuse H21 is instantaneously conducted and fused.

Abstract: PURPOSE:To control the operation of a windshield wiper in accordance with the amount of raindrops in a highly accurate manner, by installing a light receiver taking light out of a floodlight installed outside a car, while having the light receiver made up of plural light receiving elements which get light in a way of dividing an image stripe-patterned by a slit plate into two parts, a bright part and a dark part. CONSTITUTION:A floodlight 1 built in a fender mirror 3 is lighted, and when such light as collected by a concave mirror, etc., is projected to a light receiver 4 attached to the backside of a room mirror 6 through a windowpane 11, the light receiver 4 receives light through a light detector 10 via a slit plate 9. That is, an image of the slit plate 9 is divided into two parts, a bright part and a dark part and then projected to each of bright and dark light receiving elements 10a and 10b of the light detector 10. At this time, it means that a difference in light receiving signals outputted from these light receiving elements 10a and 10b shows the degree of contrast for the said image according to each case when raindrops stick to the windowpane 11 or not. So, in response to this difference in the light receiving signals, the operating speed and cycle of a windshield wiper device are automatically constrolled.
