Title: Rolling method
Inventor: SADATO NORIYUKI
IPC: B21B1/08
Filed: 1989-10-09
Abstract: PURPOSE:To eliminate a roll defect caused during rolling in a four way work roll rolling method, by offsetting a horizontal work roll couple or vertical work roll couple along the transfer pass of the material to be rolled in the specific quantity. CONSTITUTION:Vertical work rolls 13, 14 are offset in the specific quantity (l) so that the perpendicular 16 passing the center axial line thereof is located at the transfer pass downstream side of the material W to be rolled from the center axial line 15 of horizontal work rolls 11, 12. When the material W to be rolled is fed to a four way work roll rolling mill, the material W becomes rolled with its abutment on the vertical work rolls 13, 14 after its abutment on the horizontal work rolls 11, 12 first. In that case, the first abutting horizontal rolls 11, 12 are directly rotated and driven and so no roll defect is caused. Also the horizontal work rolls 11, 12 may be offset to the transfer pass upper stream side of the material W for the vertical work rolls 13, 14.

Then, in the final annealing, decarburizing annealing is carried out at a temp. essentially forming an alpha-ferrite single phase until C content reaches <=0.01%. By the above treatment, columnar crystalline grains grown from the surface toward the inner part in a direction perpendicular to the sheet surface are formed, and, in the above columnal crystalline grin, average grain diameter in a direction parallel to the sheet surface is regulated to <=1mm and <100> axes are densely integrated in a direction perpendicular to the sheet surface. By this method, the silicon steel sheet of crystalline grain structure having low iron loss and high magnetic flux density can be obtained.

Title: Nonlinear digital signal processor
Inventor: MIMURA TOSHIHIKO
IPC: H03M1/08
Filed: 1990-10-02
Abstract: PURPOSE:To decrease a sampling rate by performing prescribed nonlinear transformation by performing A/D conversion in a state where analog input is compressed, eliminating a higher harmonic according to nonlinear A/D conversion, and increasing the sampling rate to a required level. CONSTITUTION:A band-limited analog signal is inputted to a sample-and-hold circuit 1. The analog signal sampled by a nonlinear A/D converter 2 provided with (gamma) characteristic in a ladder resistor itself is converted to digital data in a state where a dynamic range is compressed. The digital data after A/D conversion is returned to a digital value provided with linear characteristic by a reverse (gamma) converter 3, and the folding distortion of high frequency is eliminated. The digital data is converted to the sampling rate of (n) times by an over-sampling converter. After various kinds of sampling signal processing are applied, the analog signal receiving (gamma) correction and prescribed processing can be outputted via a D/A converter 10 with linear characteristic.

Title: Electrode plate cutting method
Inventor: OBATA NAOKI
IPC: H01M4/04
Filed: 1992-09-04
Abstract: PURPOSE:To prevent production of whiskers or burrs at the cut surface and prolong the lifetime of a battery by allowing an upper cutter sinking to cut an electrode plate arranged between the upper cutter and a lower cutter, and hindering the upper cutter in upward stroke thereafter from touching the cut surface of the electrode plate and the lower cutter. CONSTITUTION:An upper cutter 1 is set in the vertical direction, and an electrode plate 2 is placed on a table 4. The upper cutter 1 is sunk while its inside 1a is pressed to the outside 3a of a lower cutter 3 using a cylinder 5, and thereby the electrode plate 2 is cut. When the upper cutter 1 has reached the undermost position, the upper cutter 1 is rotated by the cylinder 5 to run ahead of the lower cutter 3 so that the inside 1a of the upper cutter 1 does not contact the cut surface of the electrode plate 2 or the outside 3a of the lower cutter 3, and in this condition, the upper cutter 1 and cylinder 5 are elevated and returned to the original position. Accordingly no whiskers or burrs are generated of a nickel mat at the cut surface of the electrode plate 2. and troubles such as short-circuiting, etc., are suppressed after assembly of a battery. Thus the battery is equipped with a long lifetime.

Abstract: PROBLEM TO BE SOLVED: To provide a compact angular speed detector requiring less space for mounting on an object and capable of mounting also on a small object. SOLUTION: A microphone unit 21 can not only perform voice input but also output signals from a built-in angular velocity detection unit.

When the microphone unit 21 is tilted forward, the sound level of all loudspeakers is increased, and when the unit is tilted toward operator you, the sound level of the overall loudspeakers is lowered.  When the inclination angle of the unit comes to a specified value or more, the microphone unit 21 is leveled, even if the switch is not depressed, and therefore, the microphone considers to be in the state of being put on a desk and comes into the state of not allowing sound to be input.

Abstract: PURPOSE: To minimize residual ice by a method wherein an electric type expansion valve is so arranged that the travel thereof is set smaller for a fixed time length at the start of the defrosting operation and is altered larger when the temperature of an outdoor heat exchanger reaches a specified value to accurately melt frost frozen at a fin of the heat exchanger. CONSTITUTION: In the defrosting operation, the travel of electric type expansion valves 8a-8c is set to a specified value in a state where the operation frequency of a compressor 1 is maintained at a specified frequency and gradually increased with the passage of time. The operation frequency of the compressor 1 is kept constant regardless of the altering of the travel. With the gradual increase in the travel of the expansion valves 8a-8c, a high temperature/high pressure refrigerant gradually flows into an outdoor heat exchanger so that heat is transmitted to frost as a whole adhering being frozen to a fin of the heat exchanger to minimize residual ice.  Then, when the heat exchanger reaches a specified temperature, the travel of the expansion valves 8a-8h is increased and a defrosting end signal is transmitted from a controller 11 to return the operation to heating from the defrosting operation.
