Title: Preparation of amine oxide
Inventor: KASURIIN SUUZAN ROORENZO
IPC: C07B61/00
Filed: 1989-08-28
Abstract: PURPOSE: To obtain an amine oxide with a low nitrosamine content by reacting a tertiary amine with aqueous hydrogen peroxide in the presence of titanium metal.  
     CONSTITUTION: A tertiary amine is reacted with aqueous hydrogen peroxide while in contact with titanium metal at a temperature of 10-100°C for 1-24 hours to give the objective product. Addition of carbon dioxide to the reaction mixture gives an amine oxide which has a lower content of nitrosamine or is substantially nitrosamine-free. The amount of hydrogen peroxide employed is 1-5 moles per mole of the tertiary amine. Titanium metal is employed in such an amount that the titanium surface of 5-500 cm 2  per liter of reaction liquid volume is given and carbon dioxide is employed in an amount from 0.005 wt.% up to the solubility limit in the tertiary amine.

Title: Slip controller of fluid joint
Inventor: FUJIWARA TAKUJI
IPC: F16H61/14
Filed: 1989-08-25
Abstract: PURPOSE:To improve the responsiveness of control and the performance of convergence by setting a target value of differential pressure which controls slip conditions from the relation between an input torque and the input difference between input rotation and output rotation, and performing correction with deviation between the difference and the target value. CONSTITUTION:In a slip control device C of a fluid coupling A, in performing slip control by the differential pressure control between a fastening chamber of lockup clutch B and releasing chamber thereof, a differential target value is set with a setting means K, and a target differential pressure is set from the relation between an input torque and the difference between input and output rotations in correspondence with the target rotation difference preliminalily set by a setting means E based on the difference between the input torque and input and output rotation difference detected by detection means D, G. The differential pressure is controlled through differential pressure control means F. In this case, a correction means H corrects the target pressure difference in response to the deviation between the actual input-output rotational difference and the target rotational difference. It is thus possible to improve the responsiveness, convergence and stability of control against fluctuation of transmission torque and aging change.

Abstract: PURPOSE:To enable an ink layer to be easily transferred onto a printing paper and reduce printing noise, by supplying an ink-supplying means with energy other than the energy generated by impact of a printing means at the time of printing. CONSTITUTION:A hammer and hammer vibrator 4b is constituted of a magnetostrictive vibrator, and strikes against a daisy wheel 32 while being vibrated at the time of printing. The drive of a hammer-pressing solenoid 9 is transmitted to the hammer and hammer vibrator 4b through a hammer layer 4c to cause the hammer and hammer vibrator 4b to strike against the daisy wheel 32. Then, a type part of the daisy wheel 3 is brought into contact with an ink ribbon 62 and a printing paper 2. A this time, the vibration of the hammer and hammer vibrator 4b is transmitted to the type part, the ink ribbon 62 and the printing paper 2, so that an ink is easily transferred to the printing paper 2 and easily fixed under the functions of the mechanical stress and the heat generated by the vibration. When the frequency of the vibration is set to be, for example, not less than 20KHz, the sound arising from the vibration is inaudible to men.
