摘要:
Air-hardenable steels of duplex bainite/martensite microstructure consisting essentially of 0.10 to 0.7% C, 0.1 to 2% Si, 2.1 to 3.5% Mn, 0.0005 to 0.005% B, up to 3.5% Cr and preferably containing Cr in amount of at least 0.1%, balance Fe except for incidental impurities. Optional elements are up to 1.5% W, 1.0% Mo, 0.15% V, 0.2% S, 0.1% Ca, 0.1% Pb, 0.1% Ti and 0.2% total rare earths. At least 1.0% Cr is especially preferred and if below such amount, total Mn and Si is at least 3% and in such case, if C is under 0.47%, at least 0.6% Si is present. The steels are hardenable to R.sub.c 2o to R.sub.c 58 and have a hardenable diameter in the range between 35 mm and 80 to 100 mm by air-cooling only, together with good strength, toughness and fatigue- and wear-resistance.

摘要:
The invention discloses a method and system for guiding a packet data protocol activation. The method includes determining whether a packet data protocol is activated and if the determination result indicates that the packet data protocol is not activated because of including a wrong service access point name, analyzing service access point name information causing the packet data protocol not activated; introducing in an associating database for associating service access point name reason information causing the packet data protocol not activated and a guide information for properly setting the service access point name; inquiring the associating database based on the service access point name reason information obtained by the analyzing and obtaining the guide information for guiding a user to properly set the service access point name; and transmitting the guide information for guiding the user to properly set the service access point name to the user side. According to the method and system of the invention, the guide information may be generated automatically before the activation of the protocol to thereby reduce the maintenance workload for these functions and to thereby properly guide the user to have the related services provisioned and accessed.

摘要:
Embodiments of the present invention relate to a profiled light guide plate, a backlight module and a liquid crystal display device. In the profiled light guided plate according to the embodiments of the present invention, because the reflectivity of the profiled assembly is less than that of the light entry assembly, the emergent angle of the light beam entering into the profiled assembly from the light entry assembly is larger than the incident angle thereof, which causes the light beam entering from the light entry assembly into the profiled assembly to converge towards the central part of the profiled assembly, away from the ramp of the profiled assembly, thereby decreasing the amount of light leakage from the ramp.
摘要:
A liquid crystal display panel according to an embodiment of the present invention comprises: a backlight source; a liquid crystal cell; and a polarization adjusting layer disposed outside the liquid crystal cell and used to adjust the polarization direction of the linear polarized light emitted from the liquid crystal cell and transmitted through the polarization adjusting layer, wherein the polarization adjusting layer comprises a base body and optical anisotropic crystal grains dispersed within the base body. Also a liquid crystal display device is provided.
