Title: Hydrocarbon solution containing organo-magnesium compound, and its preparation
Inventor: TSUYAMA SHIGEO
IPC: C07F3/02
Filed: 1979-08-09
Abstract: PURPOSE: To prepare the titled solution which is free from ether and therefore suitable as a polymerization catalyst, etc. and easily handleable, by reacting an ether- containing solution of an alkyl magnesium halide with an alkyl lithium, and substituting the solvent in the reaction product with hydrocarbon, etc.  
     CONSTITUTION: A hydrocarbon solution of an isopropyl group-containing dialkyl magnesium compound of formula (R is n-C 4 H 9 , n-C 3 H 7  or C 2 H 5 ; 0.4≥a≥1.6). Since the solution is free of a polar compound such as ether, it is useful as a raw material of a vinyl monomer polymerization catalyst, Ziegler-type olefin polymerization catalyst, etc. The high magnesium content and the low viscosity of the solution ensure substantial advantage in handling in an industrial scale. The solution can be prepared, e.g. by carrying out the conventional Grignard reaction in an ether solvent and then substituting the reaction solvent with a hydrocarbon or by carrying out the Grignard reaction completely in a hydrocarbon.

Title: Chattering preventing circuit
Inventor: UEKI MASARU
IPC: H03K5/1252
Filed: 1981-06-30
Abstract: PURPOSE:To prevent chattering having no dull output waveform, by releasing  the reset mode of a shift register with a contact signal and at the same time  feeding a shift input. CONSTITUTION:When a contact S is closed, the flip-flops FF1-FF4 are reset to set an output OUT at a low level. In this case the FF1-FF4 are reset before the inversion of the FF4 althrough the contact S has chattering. Thus no chattering is caused to the output. When the contact S is opened, the reset mode is released for the FF1-FF4. Then the FF4 is inverted at the 4th clock CK to set the output at a high level after the chattering is eliminated for the contact S.

IPC: B62D5/30
Filed: 1983-06-07
Abstract: PURPOSE:To prevent power loss and to obtain automatic PTO pump operation at the time of emergency by connecting an emergency PTO pump to an axle via a clutch in such a manner that during engine operation the clutch is disconnected by oil pressure from an engine-driven hydraulic pump while during engine stop the clutch is connected by means of a coil spring. CONSTITUTION:In a normal run, pressurized oil from a hydraulic pump for an oil pressure clutch enters through an oil passage 36 and fills a ring-shaped oil chamber 33 via an oil passage 35. As a result, a cylindrical shaft 20 moves right against the force of a coil spring 21, and a clutch claw 30 at the left end of the cylindrical shaft 20 is disconnected from the clutch claw 31 of a driving shaft 12. Accordingly, no driving force is transmitted to the input shaft 18 of a PTO pump 10 engaged as a spline with the right end of the cylindrical shaft 20. At the time of emergency such as engine troubles, since no oil pressure from the hydraulic pump is supplied to the said oil passage 36, the cylindrical shaft 20 is moved to the left by the coil spring 21, thereby engaging the clutch claw 30 with the claw 31. With this contrivance, while the car is being tracted rotation of its wheels is able to rotate the PTO pump 10.
