Title: Circuit for generating muting release signal of video disc player
Inventor: YAMADA HIDEO
IPC: H04N5/93
Filed: 1982-06-16
Abstract: PURPOSE:To generate a precise muting release signal by providing the titled device with a means to generate voltage corresponding to the rotation of a motor driving a video disc and detecting that the rotation of the motor reaches a prescribed number of revolution through the comparison of the voltage output with reference voltage. CONSTITUTION:A disc device having a fixed line speed is provided with a motor with a frequency generator. The output frequency is converted from frequency to voltage by a frequency detecting circuit 9 and the converted signal is impressed to one input of each of the 1st and 2nd voltage comparators 11, 12. Reference voltages Vth2, Vth1 are impressed to the other inputs of the voltage comparators. In a range of a prescribed number of revolution both the voltage comparators 11, 12 output ''1'' to an AND circuit 13. The outputs of a monostable multivibrator which are triggered by the negative edges of a reproducing cynchronous signal and a synchronous reference signal are impressed to an OR circuit 14. Consequently, a muting release signal which is ''1'' at the prescribed number of revolution can be obtained from the AND circuit 15.

Abstract: PURPOSE:To obtain a piezoelectric body whose piezoelectric characteristic will not be changed even when a thermal shock is added by performing a polarization processing to the piezoelectric body, and performing an inverse polarization processing so that a difference between a preliminarily decided resonance frequency and an antiresonance frequency can be obtained. CONSTITUTION:Each kind of oxide Pb3O4, SnO2, Sb2O3, Nb2O5, ZrO2, TiO2 and MnCO3 is used to mix so that the oxide is composed with Zr and Ti of 50-100mol, and Sn, Sb, and Nb of 50-0mol for Pb of 100mol, and molded by adding an organic binder, and the molded body is baked. So that a piezoelectric porcelain can be manufactured. The polarization processing is performed to this piezoelectric body in almost 2 hours at 100-160 deg.C by impressing a high electric field which is 40-60kV/cm. The frequency characteristic of the piezoelectric body to which the polarization processing is operated is measured, and a difference DELTAf between a resonance frequency fa and an antiresonance frequency fr is obtained. Next, the frequency of the piezoelectric body is made close to a specific frequency by decreasing the DELTAf by impressing (inverse polarizing) the electric field having a constant strength to a direction different from the polarizing direction of the piezoelectric body.

IPC: B01J25/02
Filed: 1982-06-14
Abstract: NEW MATERIAL:The 7-octenamine of formula CH2=CH(CH2)5CH2NH2. USE:Synthetic intermediate of anion exchange membrane, polymer modifier, pharmaceuticals, agricultural chemicals, dyes, and various other useful materials. PROCESS:7-Octenamine can be prepared by the reductive amination of 7-octen- 1-al with ammonia and hydrogen in the presence of a hydrogenation catalyst (e.g. Raney Ni). The reductive amination can be carried out either by the one- step process comprising the reaction of 7-octen-l-al with ammonia and hydrogen at the same time, or by the two-step process comprising the first step to react 7-octen-1-al with ammonia in the presence or absence of a condensation agent such as inorganic or organic ion exchange material having ammonium ion, and the second step to hydrogenate the produced imine. The two-step process gives higher selectivity of 7-octenamine.
