Abstract: PURPOSE:To enable the electroplating of magnetic powder which is heretofore difficult by stirring a plating bath in which the magnetic powder is suspended, energizing an anode plate and the iron core surface of an electromagnet on a cathode side and simultaneously energizing an electromagnet coil, thereby executing the electroplating. CONSTITUTION:The anode plate 2 is provided on the bottom part of an electrolytic cell 1 and the cathode 3 opposite thereto is provided on the upper part of the cell 1. The iron core surface 4 of the electromagnet 10 constitutes directly the cathode surface of the cathode 3.

Abstract: PURPOSE:To readily and inexpensively produce in a high yield, a (-)-(S)-3- methylamino-4-methylenepyrrolidine derivative having a high optical purity and useful as a raw material for substituents to be introduced into various pyridone carboxylic acid series antibiotics. CONSTITUTION:A 3-methylamino-4-methylene pyrrolidine derivative of formula I (R is H, amino-protecting group) and L-(+)-tartaric acid in a molar ratio of 2:1 are subjected to a salt-forming reaction to form a tartaric acid salt of formula II. The salt of formula II is treated with a base and subsequently subjected to a protecting group-removing reaction to effectively and simply produce a (-)-(S)-3-methylamino-4-methylenepyrrolidine derivative. The L-(+)- tartaric acid is very inexpensive and can resolve the compound of formula I in a half amount in comparison with conventional methods. The L-(+)-tartaric acid does not require any complicated operation on the resolution and crystallization of the compound of formula I, and gives (-)-(S)-3-methylamino-4-methylene pyrrolidine derivative of formula III substantially quantitatively in a high yield of >=90% and in the optically pure form by a single crystallization and resolution process.

IPC: B05D7/00
Filed: 1990-11-28
Abstract: PURPOSE:To form intact solid body by damping waste pellet surface with high molecule latex sufficiently and then drying and cladding it with water proof high molecule skin. CONSTITUTION:After injecting latex 1 in which rubber particle of styrene- butadien series is scattered, into a dram can 4 charged with pellets 3 consisting mainly of inorganic salt and soaking the pellets 3 for ca. 1 minute, the latex 1 is drained completely out of a draining mechanism 5.

After draining latex 1, it is left for an hour or dried by force and then the agent 6 volatilizes to form high molecule skin charged finely with high molecule particles 8. By injecting water hardening material paste 2 into this, an intact cement hydrate layer without crack is formed as there is no interaction between pellets 3 and solidifying material. By this, the strength of the solid becomes over 10 times and leaching rate of radioactive species in the pellets 3 is lowered by more than one figure.

Title: Structure of secondary side of current transformer
Inventor: SUENAGA KIYOYOSHI
IPC: H02H7/04
Filed: 1994-12-26
Abstract: PURPOSE: To prevent the burning of a current transformer which is caused by an open circuit of the secondary side of the current transformer. CONSTITUTION: Secondary terminals K2 and L2 of a current transformer CT are connected between screw shafts 12a and 12d through a washer for a DIAC to which a DIAC semiconductor 14 is connected. When an ampere meter A is connected, a shorting piece 20 is connected between the screw shafts 12a and 12d to form a closed circuit at the secondary side of the current transformer CT. After the ampere meter A is connected under such a condition, the shorting piece 20 is removed and then measurement of current is conducted. When the secondary side of the current transformer CT becomes an open circuit by mistake, high voltage appears at the secondary terminals K2 and L2 and thereby the DIAC semiconductor 14 comes to a conduction state and then a potential difference between the secondary terminals K2 and L2 becomes small and therefore the burning of the current transformer CT can be prevented.
