Title: Production of low-yield ratio high tensile steel plate
Inventor: TAKASHIMA NOBUTSUGU
IPC: C22C38/00
Filed: 1992-06-10
Abstract: PURPOSE:To stably produce the low-yield ratio high tensile steel plate having excellent weldability and welded joint toughness by subjecting a low carbon slab having a specific compsn. to hot rolling under specific temp. conditions, then to rapid cooling down to a specific temp. range. CONSTITUTION:The slab of the compsn. contg., by weight %, 0.05 to 0.30% C, 0.05 to 0.60% Si, 0.5 to 2.% Mn and 0.005 to 0.10% sol.Al or further, contg. specific slight ratios of one or >=2 kinds among Ti, Cu, Ni, Cr and Nb is hot- rolled in such a manner that the finish temp. thereof attains a temp. range of the Ar3 transformation point to 950 deg.C to form the hot rolled plate. The M (Mn%/C%) satisfying the yield ratio(YR)<75% is determined by equation I from the desired tensile strength(TS) of the hot rolled plate and the compsn. of the steel. The average cooling rate(CR) after the hot rolling is determined by equation II from the carbon equiv.(CE) expressed by equation III and TS. The density (WF) of the cooling water volume is determined by equation IV from this cooling rate and the thickness (t) of the hot rolled plate. The hot rolled plate is rapidly cooled down to 400 to 550 deg.C by this WF. The steel plate of 50kgf/mm<2> class having the low yield ratio of <75% yield ratio is thus produced.

IPC: G01N29/04
Filed: 1979-11-22
Abstract: PURPOSE: To make possible the inspection of only the propeller vane range which has the possibility that defects of more than permissible defect sizes exist internally by forecasting whether the defect internally existing in the entire area of the propeller vane develops as a fatigue crack in the actual use or not.  
     CONSTITUTION: The magnitude of fluctuating stresses to be exerted upon the pressure surface of propeller vanes for ships is calculated based on unsteady lifting surface theory, and the coefficient of the lower limit stress expansion of propeller vane material is measured empirically from the propagation rate of fatigue cracking. A method of destruction dynamically evalulating whether the defect exisiting internally in the propeller vane develops as a fatigue cracking as said defect as a starting point or not is adapted by these fluctuating stress values, the values of coefficient of the lower limit stress expansion, and the position and wall thickness of the propeller vane, whereby the maximum size (permissible defect size) of the defect sizes at which the fatigue cracking does not develop in each position of the propeller vane is analyzed. Ultrasonic flaw detection is then performed by limiting to the range where there is the possibility that the defects of the sizes larger than the permissible defect sizes exist internally.

IPC: G10H1/00
Filed: 1990-06-12
Abstract: PURPOSE:To give priority to keyboard performance during automatic performance when the keyboard performance is present, and to enable the keyboard performance such as ad-lib performance by providing a control circuit which selects performance data from a keyboard circuit and performance data from a storage device. CONSTITUTION:When the keyboard performance and sequencer performance are carried out simultaneously, the keyboard performance data is sent from the keyboard circuit 10 to the control circuit 11 and sequencer performance data is sent from the performance data storage device 13 to the control circuit 11 at the same time. When the counted value of a counter 12 is less than a constant value (n) showing a necessary time elapse, the control circuit 11 does not send the sequencer performance data to a playback playing device 14 and no sound is generated. Therefore, if the keyboard performance is initiated during the sequencer performance, the sequencer performance is placed in a sound generation stop state and the sound of the keyboard performance is generated. After the keyboard performance ends, the sound generation of the sequencer performance is restarted after the constant time indicated by the counted value (n) is elapsed. Consequently, if there is the keyboard performance during the automatic performance of a sequencer, the keyboard performance is performed preferentially and the ad-lib performance becomes possible.

Abstract: PURPOSE:To measure speed accurately even if a fluctuation signal inputted to a differential circuit is varied by inputting the output signal of an amplification degree variable amplifier circuit to the 2nd input circuit as the 2nd input signal in stead of the output signal of the 2nd voltage dividing circuit. CONSTITUTION:Plural 2nd side delay circuits 20 for delaying the 2nd output signal successively, plural 2nd side comparators 21 having the 2nd square hysteresis characteristics respectively and individually inputting respective output signals from the circuits 20 and the amplification degree variable amplifier circuit 22 for amplifying the output signal of the 2nd voltage dividing circuit with the amplification degrees corresponding to respective output signals of the comparators 21 are formed in a correlation type speed meter. The output signal of the circuit 22 is inputted to the 2nd input circuit 8 as the 2nd input signal in stead of the output signal of the circuit 14. When a signal 14a is sharply varied and the 2nd output signal 8a exceeds the allowable input range of a multiplier 9, the amplification degree of the circuit 22 is changed in stages and the signal 14a is included within the allowable input range. Consequently, the speed can be accurately measured even if a fluctuation signal inputted to the differential circuit 7 is varied.
