Title: Method for oil-quenching steel
Inventor: TANAKA YASUNORI
IPC: C21D1/63
Filed: 1994-08-11
Abstract: PURPOSE: To enable the oil-quenching without deformation, particularly in a thin member by pressurizing the oil surface until the temp. of a treating material during quenching becomes a specific temp. and thereafter, smoothly shifting the oil surface pressure to the atmospheric pressure. CONSTITUTION: The oil surface is made to be under pressure until the temp. of treating material becomes the specific temp. or below during quenching. By this method, the quick change of cooling characteristic in the transition point (the characteristic temp. of the quenching oil) from a vapor film step to a boiling step is relaxed. Further, after passing through the characteristic temp., the oil surface pressure is smoothly shifted to the atmospheric pressure or the pressure near the atmosphere. By this method, the cooling speed can smoothly be recovered till coming to the Ms point.  Further, the cooling curve A of the hot quenching oil is obtd. and the characteristic temp. is shifted to the high temp. side in a short time in comparison with the cooling curve B at the atmospheric pressure of the quenching oil and the shifting of the transition point is positioned below the curve B and the sufficient cooling is obtd. without quick change to the cooling speed.

Abstract: PURPOSE:To obtain the device which has high display quality and with which the residual image is hardly generated in the transverse electric field mode by specifying the period of time from the point when the display part is erased after displaying some patterns for a specified time to the point when the display part becomes indiscernible from the non-display part. CONSTITUTION:In this device, the wire-shaped signal electrode 3, a pixel electrode 4 and a common electrode 5 are formed on the inside of each of a pair of transparent substrates and the insulating film 7 is provided on them and further, each of the resulting substrates is coated with the oriented film 8 which is subjected to orientation treatment. A liquid crystal composition is interposed between the substrates and the bar-shaped liquid crystal molecules 12 are oriented so that their longitudinal direction is at a certain angle to the longitudinal direction of the stripe-likely formed electrodes at the time of applying no electric field. At the time of applying the electric field 9, the direction of the liquid crystal molecules is changed to the direction of the electric field and the change in light-transmissivity due to the application of the electric field 9 is effected by arranging the polarizing plate 2 in the direction of the polarizing plate transmission axis 11. At this time, the required time for recovering the brightness after continuously displaying the same patterns and characters for 30min is adjusted to <=5min. Thus, the liquid crystal display device which has high picture quality and with which the residual image is hardly generated can be obtained.

There are, therefore, no differences in the ratios at which a polyamide acid is incorporated into said films, the arranging condition of the high-polymer chains in the orientation films and how the high polymers are packed in the orientation films. The ease with which electric charges are accumulated on respective dielectric layer is consequently nearly equal and flickers are extremely decreased.
