Title: Disk brake rotor, and its production
Inventor: TEJIMA KENSUKE
IPC: C22C37/00
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a disk brake rotor applicable, in particular, to large-sized truck, having high properties, and reduced in costs by specifying the composition of elements of flake graphite cast iron. SOLUTION: Flake graphite cast iron is used as a material suitable for disk brake rotor; however, it is necessary to improve thermal conductivity and lower Young's modulus in order to improve heat check resistance. The increase in C content suffices for the above purpose but deterioration in strength is brought about. Cr, therefore, is added, but the increase of the additive quantity of Cr causes formation of chill at the time of casting and deterioration in machinability. Accordingly, it is necessary to synthetically control the content of Cr and further the contents of Mn and Cr in order to facilitate control for preventing chilling, reduce costs, and produce the material suitable for use, in particular, in a large-sized truck. That is to say, Mn content and Cr content are controlled to <0.5% and >0.5-1.5% by weight ratio, respectively.  Further, the sum total (α) of the contents of Mn and Cr is controlled so that 0.5%<=α<=1.5% by weight ratio is satisfied.

Abstract: PURPOSE: To lower the driving voltage of a liquid crystal display element of a transmission scattering type improved in contrast by paralleling the orientation of the liquid crystals in respective high polymer-liquid crystal combined films with electrode surfaces and making the orientation of the liquid crystals between the respective high polymer-liquid crystal combined films 90 deg.. CONSTITUTION: The refractive index of droplets is Ne (refractive index to extraordinary ray) for the polarization component parallel with the orientation direction in an upper layer 21 and high scatterability is obtd. as the difference in the refractive index from the polymer for the incident light on the laminated films 20 of the high polymer-liquid crystal combined films in which the liquid crystals are oriented in directions varying with 90 deg.. The orthogonal component transmitted through the upper layer 21 is eventually scattered in the lower layer 22. Consequently, the scattering degree for the high polymer-liquid crystal combined films of random orientation is improved if the distance (cell gap) between the transparent electrodes 11 is the same according to these laminated films 2.  As a result, the cell gap is made thin in order to obtain the equal scattering degree and the driving voltage necessary for controlling the transparent state and the scattered state is lowered.
