Patent JP-H02123560-A (JP)
Title: Magnetic disk device
Inventor: IKESHITA KOJI
IPC: G11B5/09
Filed: 1988-11-02
Abstract: PURPOSE:To prevent a device from being influenced by noise which seeking operation generates by detecting the seeking operation based on servo data from a servo head and stopping the reproduction of data in course of the seeking operation. CONSTITUTION:When either of a power unsafe signal from a power unsafe detecting circuit 12 and a seeking/detect switching signal SD from a servo control circuit 10 is 'L', it is a seeking state or a power source abnormal state. Then, since a chip selection signal CS becomes 'H' through a NAND gate 16 and a data system preamplifier 1 is not selected, an analog signal is not amplified. Therefore, the stable and highly reliable device which is not influenced by the noise which the seeking operation generates by a data read pulse in course of the seeking operation is obtained.

IPC: H04N1/23
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a printer which can increase a printing throughput and accompanies no oozing in printed results. SOLUTION: A printing head is moved in a direction perpendicular to a line feed direction. During the movement of the printing head, ink is jetted out from nozzles and adhered onto a medium thereby to achieve printing. The printing head has a plurality of color nozzle blocks Y, M, C each equipped with a plurality of nozzles, and a plurality of black nozzle blocks B1, B2, B3 each having a plurality of nozzles. The nozzle blocks are arranged in the order from the black nozzle blocks B1, B2, B3, color nozzle blocks Y, M, C to the black nozzle blocks B1, B2, B3 in the line feed direction. Since the black nozzle blocks are arranged above and below the color nozzle blocks, printing with a mixture of black and color in one line can be made with a small amount of pass.

Title: Production of molten low nitrogen steel with arc furnace
Inventor: MIZUKAMI HIDEAKI
IPC: C21C5/52
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To reduce nitrogen content with only the improvement of operational method of a furnace by controlling blowing speed and blowing time of oxygen and adding quantity of carbon in suitable range. SOLUTION: In a refining period, the oxygen blowing is executed at QO2 blowing speed and t* blowing time and the refining is executed while blowing powdery coke as solid carbon source during refining period by Cadd in terms of carbon. Then, the oxygen blowing speed QO2 , oxygen blowing time t* and carbon quantity Cadd are adjusted so as to satisfy the formulas I, II and III, respectively. Wherein W in the formula III is molten iron quantity (ton) at the time of completing the melting of raw material and CMD is carbon quantity (kg) in the molten iron at this time. In such a case, nitrogen in molten steel is diffused and caught into CO2 bubbles generated by reaction with the carbon in the molten steel by the oxygen blowing and comes out from the molten steel through molten slag on the surface.  At the same time, the molten slag is made to be foaming state with Co bubbles and acts to shut off the molten steel from the entering air into a furnace. In such a way, at the time of completing the refining, the molten steel having low nitrogen of <=40ppm is obtd.

Title: Camera, its exposure control method and recording medium
Inventor: KATO YOSHIYUKI
IPC: H04N5/357
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To attain real time display of a through-image even under a dark condition. SOLUTION: In the case that an exposure detected by using a CCD is less than a reference value when a through-image is displayed before photographing (NO in both S1 and S2), a shutter speed is sequentially decreased (S3). When the exposure is still less than the reference value even if the shutter speed is decreased up to a minimum speed for display (YES in S2), the exposure is secured by increasing a gain of an output signal of the CCD (S4) to prevent frame missing of the through-image. When the shutter is depressed and the gain at that point of time is not a default (NO in S6), a calculation to convert a gain increment at that point of time into an exposure time (shutter speed) is conducted (S8). Then the gain is restored to the default (S9) to prevent a noise from being mixed in a photographed image.

Title: Die spotting structure for part to be pressed
Inventor: YAMAMOTO MITSUO
IPC: B21D24/00
Filed: 1990-10-18
Abstract: PURPOSE:To perform high precision press-forming in a tight adhesion by making up the upper surface of a die for mounting a part to be pressed of a rugged curved surface and providing a magnetic attractive means for magnetically attracting the part to be pressed at a prescribed place in the upper surface of the die. CONSTITUTION:Magnetic attractive force is actuated by an electromagnet 13 to the part 22 to be pressed mounted on the surface of the die. Accordingly, though a deformation made of spring back, etc., is generated on the pressed part and the whole or part of the part to be pressed inclines to rise from the upper surface it is stuck by magnetic force closely to the upper surface of the die. In order words, since the whole of the part to be pressed is stuck closely to the upper surface of the die, spotting of a part to be pressed can be performed precisely. Further, since this adhesive state is kept while the magnetic force is actuated, precise press working can be conducted in that state. Further, torsions of a die when a pressed part is used as a reference can be grasped exactly and the die, too, can be corrected precisely.
