Title: Production of hydrazone derivative
Inventor: ISHIZUKA MAKOTO
IPC: C07C281/04
Filed: 1990-07-24
Abstract: PURPOSE:To obtain a high-purity hydrazone derivative in high yield with excellent operating efficiency by depolymerizing monochloroacetaldehyde trimer and using the resultant monomer as a raw material for production with an alkyl carbazinate in an organic solvent. CONSTITUTION:Essentially unstable monochloroacetaldehyde is once converted into trimer and stabilized for use. In the process, monochloroacetaldehyde monomer which is prepared by depolymerizing the aforementioned timer as a raw material is reacted with an alkyl carbazinate expressed by formula I (R is alkyl) in an organic solvent to afford a hydrazone derivative expressed by formula II. The hydrazone derivative can be produced in the organic solvent by the aforementioned method. As a result, special recrystallizing operation is not required after completing the reaction without requiring regulation of pH. The above-mentioned method is an industrial and advaptpgeous method. The resultant compound is useful as an intermediate for medicines, agricultural chemicals, etc.

Filed: 1992-07-23
Abstract: PURPOSE:To enable the decrease of the number of IC pin to be used by two pins by providing an amplifier varying gain on the front stage of a 1H delay element. CONSTITUTION:A video signal is constituted to be delayed 1H by a 1H delay element 20 after the signal is amplified in a gain varying circuit 17. When the gain of the element 20 is smaller than a desired value, the level of a delay video signal to be supplied to a comparison circuit 18 becomes smaller than the level of the video signal to be supplied to the other input of the comparison circuit 18. The signal level difference is detected by the comparison circuit 18 and detected voltage is held in a detected voltage holding capacity 19. By the held detected voltage, the gain of the gain varying circuit 17 increases. The operation is repeated so that the level difference between the video signal to be supplied to the comparison circuit 18 and a delayed video signal may be equal. By this constitution, the number of IC pin to be used can be decreased by 2 pins.

Abstract: PROBLEM TO BE SOLVED: To suppress the plastic deformation of an intermediate steel plate edge part near upper and lower mounting flanges or the swelling of a rubber layer edge part by setting the form coefficient of the upper and lower rubber layer peripheral parts near the mounting flanges higher than the value of the central rubber layer.
