Title: Mandrel bar for hot rolling of seamless pipe
Inventor: NAGASE YUTAKA
IPC: C23C28/02
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To prolong like time of Mandrel bar by forming multi-layer chrome planting layer having more than 2 layers on the surface of said mandrel bar so that growth of cracking which take place in chrome planting layers is stagnated between adjacent layers. SOLUTION: It is desirable that the base material of said mandrel bar is steel for hot working tools. The outer diameter is determined by considering final thickness of chrome plating. And mechanical processing is carried out. Then the base material is abraded to have suitable surface roughness and layers of multi-layer chrome planting is formed. It is desirable that the total thickness of the multi-layer chrome planter is from 1 to 100 μm. Also it is desired that before the formation of chrome planting layer quenching treatment be conducted to give to the base material mechanical strength to work as a hot working tool. Although cracks occur inside the chrome planting layer due to repeated rolling, cracks throughout from the surface to the base material tend to decrease because the occurrence and growth of cracks is prevented between chrome planting layers.

Abstract: PURPOSE:To strengthen the logic function of a logic circuit device per gate by maintaining the impedance ratio to the gates as an inverting logic circuit constant, and so composing to connect transistors that a logic threshold voltage is invariable. CONSTITUTION:The source electrodes of driving FETs 11D, 12D are connected to a power line VSS, and drain electrodes are both connected to an output terminal X. The drain electrode of a load FET 11L is connected to a power line VDD, and a source electrode is connected to a gate electrode, i.e., the output terminal X. An input signal is applied to the gate electrodes A, B of the FETs 11D, 12D to obtain an inverting logic signal from the terminal X. The two FETs 11D, 12D are connected in parallel, and since either one FET is cut OFF in operation, the W/L ratio at the FET side is the same as that of one FET, and the value becomes 10. The W/L ratio at the load FET side is 6, and the impedance ratio accordingly becomes 0.6. Thus, the logic function per gate is strengthened to improve the performance in the circuit operation.
