IPC: G01N19/02
Filed: 1992-05-12
Abstract: PURPOSE:To obtain the frictional-resistance control method, of a frozen road surface, wherein the surface state of the frozen road surface can be measured in a nondestructive manner and the state of the frozen road surface can be measured simply while an initial state is kept. CONSTITUTION:The temperature of ice on a frozen road surface and the surface electric resistivity of ice are measured. The maximum frictional coefficient of the frozen road surface and that of a tire are estimated from two measured values. The temperature of the ice on the surface of the frozen road surface 1 is measured by means of a surface thermometer 2, the surface electric resistivity of the ice is measured by means of a surface high-resistivity meter 3. Since a correlation exists between the two measured values and the braking-power coefficient of the tire 4 on the frozen road surface 1, the average maximum frictional coefficient of the tire 4 on the frozen road surface 1 is estimated from the correlation.

Title: Heater structure
Inventor: ONOZAWA SACHIKO
IPC: H01L21/22
Filed: 1994-06-29
Abstract: PURPOSE:To make uniform the temperature distribution on both surfaces of a semiconductor wafer by a method wherein at least the thickness of the circumferential part of one of a pair of heaters is formed thinner than the center part. CONSTITUTION:This heater structure is composed of a pair of opposing heaters 30 arranged in a reaction chamber 32 leaving a space between them, a susceptor 34 on which a wafer 36 which is inserted between the heaters, and a susceptor supporting rod 38. Between a pair of heaters 30, the circumferential part of at least one of the heaters is thinly formed leaving the part opposing to the wafer in the center part. As resistance becomes higher on the thin part of the heaters 30, the temperature rises on the thin part, and on the contrary, the temperature of the thick part goes down. As a result, the temperature distribution on the plane of the wafer 36 can be maintained uniform even when the space between the opposing heaters becomes small, because the temperature rise in the center of the wafer 36 by the effect of the radiation from the heaters 30 can be decreased.

Title: Steelmaking method
Inventor: SAKA KENJI
IPC: C21C1/04
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To reduce the treating cost of desiliconizing agent without charging Mn raw material and to improve the handlability of the desiconizing agent by adding the desiliconizing agent consisting essentially of iron oxide into molten iron tapped from a blast furnace and stirred with an impeller and executing the desiliconizing treatment. SOLUTION: At the time of adding the desiliconizing agent and flux, it is desirable to add steelmaking slag produced in the other steel-making process. Since the desiliconizing agent charged on the molten iron can forcedly be suspended and floated in the molten iron for a fixed time by stirring with the impeller having intense stirring force, even under condition which the desiliconizing agent is not fully formed to slag, the desiliconizing effect with solid-liquid reaction is obtd. Therefore, in case of being the same desiliconized quantity as the conventional method, this treatment can be obtd. for the short time, and in case of being the same treating time as the conventional method, more desiliconized quantity can be obtd.  Since the siliconizing treatment can be executed even in case the desiliconizing agent is not fully formed to the slag, iron loss developed caused by absorption into the slag can be restrained as much as possible.
