Abstract: PURPOSE:To provide the prevention of the embrittleness of a heat affected zone, etc. by welding a B-contg. CrMoV cast steel contg. specific weight % each of B, Cr, Mo and V by a CrMoV steel filler metal contg. prescribed % each of Cr, Mo and V then subjecting the steel to a heat treatment. CONSTITUTION:The B-contg. CrMoV cast steel contg. 0.0005-0.005% B, 0.5-2% Cr, 0.5-2% Mo and 0.1-0.5% V is welded by the filler metal of the CrMoV steel contg. 0.2-1% Cr, 0.5-2% Mo and 0.1-0.5% V. The steel is subjected to the heat treatment for annealing at 1,000-1,100 deg.C and tempering at 650-750 deg.C after welding. The generation of the hardness peak at the boundary between the base metal and the weld metal is prevented and the embrittleness is prevented by the above-mentioned method. The creep strength of the deposited metal for a Larson-Miller parameter P is improved as shown by a solid line.

Title: Electric car controller
Inventor: KOJIMA SHIGERU
IPC: B60L15/20
Filed: 1987-10-21
Abstract: PURPOSE:To reduce frequency for switching notch, by controlling an electric car so that torque coinciding with a force receiving in the direction of moving backward may be generated when the electric car is set in the state of constant- speed operation. CONSTITUTION:A notch command converting section 2 converts the power running notch or brake notch of output generated from an automatic train operation command section 1 to torque signal. In the meantime, when the output of constant-speed operation command signal is generated from the automatic train operation command section 1, then a speed pattern generating section 3 determines correction torque from a speed deviation ALPHAV between a speed at the time of receiving the constant-speed operation command signal, and a present speed. Then, the making of a switch 5 made when the output of the constant-speed operation command signal is generated adds the correction torque and the torque signal of the notch command converting section 2, and generates the output of control signal. As a result, frequency for switching notch can be reduced, and riding comfort can be improved.

IPC: H04S5/00
Filed: 1994-10-31
Abstract: PURPOSE: To obtain the spreading feeling of sound more than ever by remarking the inter-ear correlation coefficient of a listener. CONSTITUTION: This generator is to control correlation based on the inter-ear correlation coefficient ρLR of sound pressure vocalized from first and second loudspeakers 12, 22, and the inter-ear correlation coefficient ρLR can be increased/decreased by increasing a component added on adders 14, 24 with positive phase or negative phase.
