Title: Production of l,l-ethylenediaminedisuccinic acid using dihaloethane as raw material
Inventor: YAMAMOTO HIROSHI
IPC: C07C229/16
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain a compound excellent in biodegradability in high yield and purity by reacting a dihaloethane with L-aspartic acid. SOLUTION: A dihaloethane is reacted with L-aspartic acid in an alkaline condition having pH9-12 in the presence of a metal ion, as necessary in a solvent (e.g. diethylene glycol) at 80-250 deg.C under 1-32atm internal pressure. Dihaloethane is used in an amount of 0.5-10 times by mole based on 1mol L-aspartic acid. L-Aspartic acid is preferably used as an aqueous solution of an alkali metal (e.g. NaOH) and the metal ion is selected from among a heavy metal [e.g. Fe(II)] and an alkaline earth metal [e.g. Mg(II)]. The objective compound is useful as a biodegradable chelating agent, a cleaning agent composition, a detergent builder, a heavy metal blocking agent, a stabilizer for peroxide, etc.

IPC: H03G5/16
Filed: 1979-03-16
Abstract: PURPOSE:To make loudness control by automatically varying the characteristics of an amplifier according to the magnitude of an input signal, by forming a fixed circuit. CONSTITUTION:An input signal from input terminal 2 is amplified by amplifier 1, the output of which is positively fed back to voltage variable attenuator 7 via parallel-connected LPF5 and HPF6.

Furthermore, at the time of the commencement of secondary transfer, information on the commencement of secondary transfer is written in the nonvolatile memory 10. After that, printing is continued as usual, and when printing is finished normally, information on the commencement of the secondary transfer recorded in the nonvolatile memory 10 is eliminated. If printing is not finished normally through any reasons in the way of printing after the secondary transfer, information remains in the nonvolatile memory 10 having the commencement of the secondary transfer.

Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a device for demultiplexing and decoding multiplexed and encoded video/audio signal. SOLUTION: Each time the packet of desired channel of a multiplexed and encoded video/audio signal is inputted, at a sharing circuit 100, the demultiplexing processing of the multiplexed signal is performed for demultiplexing this packet into the class of encoded video signal or encoded audio signal and this result is temporarily stored in a RAM 3 but when the demultiplexing processing of the multiplexed signal is not performed, decoding processing is performed for decoding the encoded audio signal stored in the RAM 3 to a digital audio signal. When this digital sudio signal is decoded for unit data amount, it is transferred, temporarily stored in a RAM 8 and read out by an audio output circuit 11 at an LSI 101.  Since the decode and transfer processing for the unit data amount is performed during the demultiplexing processing of the multiplexed signal, its processing time is not fixed but since this digital audio signal is read out of the RAM 8 at fixed speed by the audio output circuit 11, this signal is outputted from an output terminal 10 as continuous digital audio signals at a prescribed frequency.

Title: Pressure releasing device
Inventor: NAITOU TAKEHIKO
IPC: H01F27/40
Filed: 1979-03-22
Abstract: PURPOSE:To decrease the number of times of operation of a pressure release valve and reduce remaining pressure, by oprating the pressure release valve after a prescribed time since internal pressure rises above a prescribed lvel. CONSTITUTION:A pressure release port 6 is provided at one end of the horizontal part 5b of a pressure release pipe 5. A pressure release valve 8, which is energized by a spring 7 in a direction to close the pressure release port 6, is provided. A pressure chamber 12 and the internal space 14 of a container 1 are always connected to each other through an orifice-like bypass 13. The cross- sectional area of the bypass 13 is set in consideration of the volume of the pressure chamber 12 and internal pressure, which is expected to act when an accident occurs. As a result, a prescribed time lag is set for a pressure change, due to the rise in the internal pressure, to be transmitted to the pressure chamber through the bypass 13. According to this constitution, opposite equal forces are applied to pressure reception faces 8a, 11d of equal area because of the internal pressure P higher than a prescribed level at the osccurrence of the accident so that the pressure release valve is not operated. After a prescribed time since the occurrence of the accident, the force applied to a pressure reception part 11 becomes stronger than the force of the spring 7 and drives the pressure release valve 8 to open the pressure release port 6 to instantaneously release a large amount of gas. After that, the pressure in the pressure chamber 12 falls and the valve 8 is automatically returned by the spring 7 to close the port 6.
