Abstract: PURPOSE:To improve the wear resistance and deformation resistance of shape steels by rapidly cooling the shape steels which hold the heat after hot rolling to cause martensite transformation, then heating the shape steels to a specific temp. range and rapidly cooling the heated shape steels. CONSTITUTION:The shape steels for a fork lift mast which are at the A1 transformation point or above and <=1300 deg.C by the heat retained after the hot rolling or by heating from the outside are rapidly cooled by a refrigerant liquid such as water to cause the martensite transformation. The shape steels are thereafter tempered by heating to the temp. above 300 deg.C and below the A1 transformation point and are then hardened by rapid cooling with water, etc. The shape steels after the hot rolling and otherwise cooled by using compressed air or compressed water-contg. air at the rate at which a fine pearlite structure is formed until the pearlite transformation ends; thereafter, the shape steels are hardened by rapid cooling. The wear resistance of the shape steel part for masts in contact with rollers is thereby improved and the deformation resistance in the corner part at the neck of flanges and webs is increased.

Title: Line drive circuit
Inventor: FUJII TAKAICHI
IPC: H04L25/02
Filed: 1984-03-27
Abstract: PURPOSE:To reduce the effect of external noise by reducing the output impedance in the pulse transmission timing and matching said output impedance with the characteristic impedance of a line. CONSTITUTION:The power is supplied to a switch 6, the primary winding of a coupling transformer 4 and a switch 8 from a power supply +V in a pulse transmission timing mode. In such a case, a low impedance of the +V is connected directly to the primary winding of the transformer 4. Thus the impedances emerging at line terminals 1 and 1' are set at extremely low levels. While in a non-transmission timing mode of pulse, switches 5 and 6 are opened with switches 7 and 10 closed respectively. Thus resistances 2 and 3 are connected in series to the primary winding of the transformer 4. The series resistance value of both resistances 2 and 3 is converted at the primary side of the transformer 4 and set at a level approximately equal to the characteristic impedance of lines connected to terminal 1 and 1' respectively.
