Title: Aluminum clad steel plate
Inventor: KUBOTA MASAROU
IPC: C23C2/12
Filed: 1980-08-04
Abstract: PURPOSE:To prevent the exfoliation of an Al clad steel plate at the joining faces due to the production of an intermetallic compound at the joining faces by specifying the C and N contents of the steel plate as the core material and coating the surfaces of the plate with molten Al-Si by hot dipping. CONSTITUTION:In the manufacture of an Al clad steel plate having 0.0050- 0.200% N content and <=0.02% C content is used as the core material 1. This plate is dipped in a molten Al-Si alloy contg. 1-15% Si to form Al-Si alloy layers 2 by hot dipping. After cleaning the surfaces, Al or Al alloy plates 3 are pressure- welded by rolling to manufacture the Al clad steel plate. Since free N is contained in the steel plate as the core material, and the plate has such a low C content, no intermetallic compound is produced between the core material 1 and each of the Al- Si layers 2, and divided Fe-Al-Si alloy layers 4 are formed to prevent the exfoliation of the core material 1 and the clad materials 2, 3.

Title: Arc welding machine
Inventor: YASUHARA YOSHIMICHI
IPC: B23K9/12
Filed: 1981-07-07
Abstract: PURPOSE:To make the regulation of one-dimensional welding conditions possible with respect to different welding methods with simple circuits and few parts by dividing the AC voltage signal proportional to welding voltage by resistors and appying the same to a rectifier circuit. CONSTITUTION:When a selection switch 24 is shifted to the position A, the voltage on the secondary side of a transformer 1 is applied as it is to a diode bridge 20 constituting a rectifier circuit. When it is shifted to the position B, the voltages divided by resistors 22, 23 are applied to the bridge 20. If the voltages applied to the bridge 20 vary in such a way, the control command voltages for a wire feed motor 7 vary and therefore the running speeds of the motor 7 vary as well. Namely, different welding currents are obtained with respect to the same welding voltage by changing the voltage dividing ratios of the resistors.

Title: Semiconductor integrated circuit device
Inventor: OKUAKI KATSUMI
IPC: G11C29/00
Filed: 1990-04-23
Abstract: PURPOSE:To especially improve the defect of a stand-by current by providing the semiconductor integrated circuit device with a transistor (TR) whose driving capacity is lower than a resetter TR in a row decoder whose source part is connected to a ground level. CONSTITUTION:In a stand-by state, a word line 5a is connected to the ground level through a reset TR QN2a in a row decoder driver part 2a and an n- channel TR Qn3a whose driving capacity is lower than the TR QN2a. When an unspecific defective word line 5a fixed to a 1/2Vcc or Vcc potential level due to any defect is detected at the time of redundancy R/W, the defective word line 5a is separated from the resetter TR QN2a having higher driving capacity in the driver part 2a by disconnecting a fuse connected to the defective word line 5a. As the result of the separation, a current route from the defective word line 5a to the ground level through the resetter TR QN2a which is the main route of a stand-by defect current is interrupted. Consequently, the stand-by current is sharply reduced and the defect of the stand-by current can be im proved.
