Title: Method and equipment for measuring color tone of metal plate
Inventor: NAKAMURA MANABU
IPC: G01J3/50
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To measure the reflection luminance under the sun light accurately using an artificial light source and to measure the color tone of a metal plate by binding the positional relationship between projection and reception of light for detecting the relative ratio of reflection luminance with highest sensitivity. SOLUTION: Reflection luminance ratio between metal plates a and b is measured while varying angles α, β, γ and δvariously and the range of each angle is set by determining an arrangement for maximizing the reflection luminance ratio (uneven color tone is most prominent). More specifically, a substantially parallel light beam is projected from a projector 1 in such a direction as the inclination angle α from the normal N to the surface of the metal plate 5 is 25-35 deg.. In a plane defined by turning a plane including the projecting direction and the normal N by an angle β of 130-140 deg. about the normal N, reflected light from the metal plate 5 is received by a silicon diode 2a in such a direction as the angle β from the normal N is 40-50 deg. and converted into a luminance through a signal processor 3 (computer).  According to the arrangement, reflection luminance of a metal plate can be measured with a sensitivity similar to that in case of identification under the sun light.

Filed: 1993-12-17
Abstract: PURPOSE:To enable any abnormal misfire to be detected with high accuracy by changing a misfire recognition level to that higher than a normal one and corresponding to a torque-decreasing controlled variable during the execution of torque-decreasing control such as traction control. CONSTITUTION:During operation of an engine 1, a control unit 16 determines whether or not an engine speed Ne calculated from the output of a crank angle sensor 14 and a load Ce calculated from the output of an airflow meter 9, etc., are within respective misfire detecting ranges. When those values are both within the respective ranges, it is determined whether or not a traction control execution signal is entered, and if not, angular velocity fluctuation is calculated from a signal of the crank angle sensor 14. A misfire recognition level under normal conditions which gets greater the lower the engine speed and smaller the higher the engine speed according to the engine speed Ne and the load Ce is read. Misfire recognition is carried out according to whether or not the angular velocity fluctuation is greater than a set value, and, if the fluctuation is at or greater than the set value, the occurrence of a misfire is determined.

Title: Position detecting device
Inventor: KOO KATSUTO
IPC: G06F3/0488
Filed: 1991-12-27
Abstract: PURPOSE:To reduce the invalid area of a sense part by obtaining the coordinates of a designated position with a 2nd coordinate value calculating means when a position pointer is moved to the invalid area. CONSTITUTION:A 2nd coordinate value calculating means 5 detects the coordinate value based on two signal levels including the highest one of those signal levels dependent on the distance between a position pointer 2 and a loop coil of a sense part 1. Then it is supposed that the pointer 2 moves to an area (an invalid area) where the coordinate value cannot be calculated by a 1st coordinate value calculating means 4 set in the position detecting direction of the part 1. Under such conditions, an area deciding/switching means 6 detects the movement of the pointer 2 and switches the means 4 to the means 5 to detect the coordinate value of the position designated by the pointer 2. Thus, the area can be increased for calculation of the coordinate value of the position designated by the pointer 2. Then the invalid area of the part 1 can be reduced and the availability of a position detector is improved.

Abstract: PROBLEM TO BE SOLVED: To advantageously recover boron trifluoride and sulfuric acid by reacting fuming sulfuric acid with industrial BF3 hydrate, treating a sulfuric acid by-product with hydrogen peroxide and purging BF3 with air. SOLUTION: BF3 hydrate is shown by BF3 .2H2 O, is called industrial boron trifluoride hydrate and is obtained by allowing gaseous BF3 after the use of various polymerization processes to be absorbed in water. The BF3 content is 35-65.3%, preferably 47-65.3% wt. % concentration. The concentrated hydrate contains an organic substance. The quotient obtained by dividing the number of mols of fuming sulfuric acid by the total number of mols of the free water and compound water of the hydrate is 0.5-1.5, preferably close to 1 and fuming sulfuric acid is reacted with the industrial boron trifluoride. The boron trifluoride recovered from a reactor does not contain an organic substance, CO2 , etc. An organic substance in formed sulfuric acid is oxidized with H2 O2 and BF3 is substantially removed by air purging to give colorless sulfuric acid.
