Title: Production of beta-mercaptopropionic acid
Inventor: TOMIOKA TETSUZO
IPC: C07C319/04
Filed: 1990-11-19
Abstract: PURPOSE:To obtain the subject compound in a high yield while inhibiting the by-production of thiodipropionic acid by reacting acrylonitrile with an excessive amount of an alkali hydrosulfide or alkali sulfide, further adding an excessive amount of an alkali hydroxide and subsequently heating the reaction mixture. CONSTITUTION:An excessive amount of an alkali hydrosulfide or alkali sulfide aqueous solution is reacted with acrylonitrile. The reaction solution is further mixed with an excessive amount of an alkali hydroxide and heated to obtain an alkali salt of the objective compound and a thiodipropionic acid alkali salt simultaneously. The by-produced thiodipropionic acid alkali salt is reacted with an alkali sulfide produced from the alkali hydrosulfide and the alkali hydroxide or with the excessive amount of the alkali sulfide used in the above- mentioned reaction to obtain the alkali metal salt of the objective compound, which is acidified with a basic acid such as sulfuric acid or hydrochloric acid to provide the objective compound.

Title: Smoothing process method for robot track control
Inventor: NOSE MATSUO
IPC: G05B19/4103
Filed: 1988-12-15
Abstract: PURPOSE:To prevent a dislocation of the target track that is produced before and after a smoothing process by comparing the difference between the target speed and the final speed with the difference between the present target speed and the next target speed and interpolating this comparison result along a straight line connecting an intermediate point of the discrete command value and a prescribed point. CONSTITUTION:A speed omega+1 after DELTAT is obtained by a preceding arithmetic, where (t) and omega show the present time and the target speed prespectively. Then the difference DELTAomega between the present target speed omega and a point A' showing the final speed of the preceding smoothing process is compared with the difference DELTAomega+1 between the next target speed omega+1 and the present target speed omega. Then the linear interpolation is carried out. In other words, the linear interpolation is carried out by a line OA connecting the intermediate point 0 of (t) -(t + DELTAT) and a point A of 1/2DELTAomega in the case of DELTAomega<DELTAomega+1, while, by a line OB connecting the intermediate point 0 and a point B of 1/2DELTAomega+1 in the case of DELTAomega>=DELTAomega+1 respectively. Thus it is possible to prevent a dislocation of the target track that is produced before and after a smoothing process.
