Title: Production of m-nitroacetophenone
Inventor: KATO TOSHIO
IPC: C07C201/08
Filed: 1992-03-09
Abstract: PURPOSE:To obtain the subject compound having high quality in high yield at a low cost by nitrating acetophenone and purifying the nitrated product by neutralizing in water or an alcohol. CONSTITUTION:Acetophenone is nitrated in an organic solvent (e.g. methylene chloride) with a mixed acid (e.g. sulfuric acid) containing nitric acid at <=0 deg.C, preferably -20 to 0 deg.C to obtain crude m-nitroacetophenone containing a mixture of isomers. The crude product is purified by treating with a neutralizing agent (e.g. NaOH) in water and/or an alcohol at 0-100 deg.C. The nitration of acetophenone can be carried out without using a particular reaction apparatus. A high-quality product containing little by-product can be obtained since the reaction is carried out at a minimized nitric acid consumption. The selectivity of m-site is high to enable the separation of m-nitroacetophenone at a low cost.

Title: Self-cooling fan device
Inventor: NAKAMURA TADAMASA
IPC: F04D29/32
Filed: 1979-04-24
Abstract: PURPOSE: To increase the air blowing amount of a fan by reducing the frictional torque originated in the viscous drag of the fan bearing at the time of internal temperature rise of bracket by supporting the fan driven through a sliding coupler from an output shaft on the non-rotating portion of the bracket of a prime mover.  
     CONSTITUTION: The permanent magnet 5 constituting a part of a spiral coupler is fastened to near the end of the rotary shaft 2 inside the bracket 3. On the other hand, the fan F is rotatably attached to the shaft 7 extending inside from the bracket 3 through the bearing 8. The attaching part at which the fan F is attached to the bearing 8 is made of a ferromagnetic material having a comparatively good conductivity, e.g., pure iron, etc., so that an eddy current is produced in the ferromagnetic material by means of the magnet 5 by the rotation of the rotary shaft 2 and the fan F is rotated smoothly while being slided. In short, when the internal temperature of the bracket 3 rises, the fan F rotates following the rotary shaft 2 and therefore the air blowing amount of the fan F is increased and also its function compensating for the rise of temperature is increased.
