Title: Waveform converting circuit
Inventor: NISHIMURA KIYOSHI
IPC: G05F3/00
Filed: 1984-10-19
Abstract: PURPOSE:To attain a waveform converting circuit which extracts only the AC signal waveform having the improves frequency characteristics and converts said waveform into an absolute value waveform, by deleting the working current component out of an output in response to the level of the working current which is used for gain control of a differential amplifier. CONSTITUTION:The AC voltage is applied between bases of transistors TR30 and 32, and the control current IO given from a control input terminal 50 is reduced to IO2 from IO1. Then a signal current obtained with superposition of an AC signal onto a 1/2 control current flows to the collector sides of the TR30 and 32. a current similar to said signal currents flows to the TR56 and 60 by the current mirror effect. Then the DC component is discharged to the earth line side via bypass circuits 66 and 68 owing to the sucking of IO1/2 and IO2/2 currents through the TR70 and 72. As a result, only the AC component flows to resistances 62 and 64. Thus the voltage of a half-wave rectifying waveform is obtained, and each voltage waveform is applied to an output synthesizing circuit 73 for extraction of an absolute value signal.

Abstract: PURPOSE:To enable of production of solid CO2, safely and easily, with a compact and easily operatable apparatus, by attaching a filter having a specific mesh size to the innerside of a window, and attaching a safety valve at the middle part of the heat- insulating high-pressure supply pipe or at the part connecting the pipe with the forming chamber. CONSTITUTION:The valve 5 of the high-pressure vessel 2 containing liquid CO2 is opened, and the liquid CO2 is allowed to inject through the heat-insulating high-pressure supply pipe 3 and the end nozzle 7 into the forming chamber 14. The pressure of the liquid CO2 is reduced to cause the adiabatic expansion of CO2, and the liquid CO2 is mixed with the formed solid CO2 and supplied to the forming chamber 14. If the pressure in the forming chamber 14 or the supply pipe 3 increases by any reason to a level exceeding the force of the spring in the safety valve 8, the main body of the valve 10 is shifted to release the liquid CO2 from the system and the explosion hazard can be prevented. In the forming chamber 14, only the gaseous components of the mixture are released through the filters 19, 18 while leaving the solid CO2 in the forming chamber 14. The solid CO2 is accumulated and compression molded gradually on the filter 19 in the forming chamber 14 by the pressure of the above mixture. When a sufficient amount of the solid CO2 is obtained, the valve 5 is closed.
