Abstract:
The present invention relates to an electric vehicle and to a method for controlling same. The method for controlling the electric vehicle according to the present invention comprises the steps of: using first data to calculate a first torque value in a first memory; using second data to calculate a second torque value in a second memory having a memory address separate from the first memory; and comparing the first torque value and the second torque value, determining whether an abnormality exists in the torque calculations, and controlling the motion of the vehicle.
Abstract:
Disclosed is a method of manufcturing an artificial stone, and the method includes forming an artificial-stone paste which comprises 20~90 parts by weight of silica stone, metakaolin or silica fume, 200~300 parts by weight of quartz chips, 30~36 parts by weight of water, 1.5~3 parts by weight of water-reducing agent and 0.2~3 parts by weight of pigment with respect to 100 parts by weight of white cement; injecting the artificial-stone paste in a mold; primarily vacuum-molding the the artificial-stone paste injected in the mold; secondarily vibration-molding the primarily molded artificial-stone paste; primarily curing the secondarily molded artificial-stone paste; secondarily curing the primarily cured artificial-stone paste, which induces a hydrothermal reaction and thus causes a pozzolanic reaction; relasing the secondarily cured artificial-stone paste from the mold; and surface-machining the released tartiricial-stone paste.
Abstract:
The present invention relates to a paste compsotion for artificial marble and a method of manufacturing the artificial marble using the same, which can solve the problems of efflorescence and durability in the existing cementitious marble and the problems of thermal resistance and acid tolerance in the existing organic binder-based marble, and can provide an insulating function to the artificial marble by using an inorganic binder such as an amorphous activated aluminosilicate compound and also using a lightweight particulate porous inorganic material. The method of manufacturing the artificial marble includes preparing paste for artificial marble by mixing 10~20 parts by weight of white cement, 3~10 parts by weight of amorphous activated aluminosilicate, 40~70 parts by weight of broken-stone chip, 5~10 parts by weight of water, 0.1~1 part by weight of water-reducing agent and 10~30 parts by weight of lightweight particulate porous inorganic material; pouring and vibration-molding the paste in a mold; curing the paste; inducing a hydrothermal reaction of cured artificial marble at high temperature and high pressure; and machining cured product.
