Title: Preparation of magnetic metal powder
Inventor: SUEYOSHI TOSHINOBU
IPC: B22F9/22
Filed: 1980-06-11
Abstract: PURPOSE: To prevent particles from sintering and getting out of shape when heating and reducing and provide the particles having excellent magnetic characteristics, by coating the powder particles of oxy ferric hydroxide or ferric oxide with the two components of Al and Si to heat and reduce the particles.  
     CONSTITUTION: The powder mainly comprising oxy ferric hydroxide or ferric oxide such as α-FeOOH or α-Fe 2 O 3  is dispersed in the aqueous solution of an Al compound such as e.g. Al 2 (SO 4 ) 3  and then neutralized by CO 2  blowing or the addition of an acid to coat the particle surfaces with Al(OH) 3 . When the particles are heated at a temperature of 150°C or higher, the Al component is converted into a water- containing oxide and an oxide in low and high temperature regions, respectively,  and provides a form in which the Al component is not chited into an alkaline solution, thereby forming a very compact coating. The particles are, further, dispersed  in the solution or dispersion of an inorganic or organic silicon compound in water or  an organic solvent, and, as in the above-mentioned process, the silicon compound is neutralized to coat the particle surfaces with silic acid sol. Finally the particles are heated and reduced in a gaseous phase to provide the powder mainly comprising metallic iron.

Title: Oil pan of transmission
IPC: F16H57/04
Filed: 1992-04-01
Abstract: PURPOSE:To prevent air from being suctioned by an oil filter by movement of an oil level at the time of controlling in an oil pan for a transmission. CONSTITUTION:A space in an oil pan 1 is divided into a chamber 5 on a front side in a vehicle running direction compared to an oil filter 3 and a chamber 6 on a rear side by providing baffle plates 7 and 8. The baffle plates 7, 8 are inclined such that each one end near the oil filter 3 is located to a front portion in the vehicle running direction compared to the other end. Oil in the rear chamber 6 is largely regulated in its movement to the front chamber 5 when the vehicle is controlled, while oil in the rear chamber 6 is concentrated around the oil filter for increasing an oil level around the oil filter. The oil filter is prevented from being exposed to atmosphere where oil does not exist even in controlling. It is thus possible to solve problems such as racing of an engine which may caused by suction of air from the oil filter, and shock generated thereafter.

Title: Exposure quantity adjusting method for optical device
Inventor: HIDESHIMA TAKAHIRO
IPC: G03B27/32
Filed: 1986-04-10
Abstract: PURPOSE:To determine an exposure quantity, based on the luminous intensity of a background part of projection light as a reference, by detecting a distribution of the number of picture elements by which a pulse voltage exceeds a reference voltage, and controlling the light quantity of a light source. CONSTITUTION:A pulse voltage Va of an image sensor 44, which is obtained by scanning image projection light by the image sensor 44 is compared with a reference voltage Vc which is varied stepwise at every one scan of the image sensor 44, the number of picture elements by which the pulse voltage Va becomes higher than each reference voltage Vc is counted at every reference voltage Vc, and the light quantity of a light source is controlled so that the reference voltage Vc at the time of the counting value changes suddenly coincides with the reference voltage Vc corresponding to a correct exposure quantity. That is to say, the light quantity of a light source 12 is controlled so that the reference voltage Vc (n1) by which a counting value N of a characteristic curve (c) is changed suddenly coincides with the reference voltage Vc (n0) corresponding to the correct exposure quantity. In this way, even if an image changes and an average light quantity of a photometric area changes, it can always be adjusted to an exact exposure quantity.
