IPC: B01D9/00
Filed: 1994-04-22
Abstract: PURPOSE: To cause sweating and to separate and remove a sweat oil by pressurizing a melt under an atmosphere of inert gas, cooling the melt to be crystallized, separating the residual melt from the crystal and finally degassing the crystal by reducing the pressure. CONSTITUTION: An inert gas is introduced into a melt which is pressurized to a 100-5000 bar pressure under an atmosphere of inert gas, and then the melt is cooled to be crystallized. After the residual melt is separated from the crystal, the crystal is degassed by reducing the pressure. Suitable gases here are those which are soluble in the specific melt. For example, nitrogen, carbon dioxide, ethane, ethene, propane or mixtures thereof are suitable for naphthalene/biphenyl and p-/m-dichlorobenzene systems. The pressure of the gas can be gradually reduced after the residual melt is separated. Thereby sweat oil sweated out from the crystal is removed.

Abstract: PROBLEM TO BE SOLVED: To eliminate distortion in a waveform even in the case of a modulation wave whose amplitude has information by operating immediately an AGC loop. SOLUTION: An antenna 1 receives a reception signal and a power amplifier 2 amplifies the signal. A variable attenuator 3 attenuates a gain of the reception signal according to an output voltage of a latch circuit 13.

An LIM amplifier 10 applies LIM amplification to the signal and a detector 11 detects the signal, and a comparator 12 is used to obtain a difference voltage between an output of the detector 11 and a reference voltage Vref .  When the difference voltage is positive, a timing generating section generates a timing signal Tm , a latch circuit 13 latches a detection signal S12 and a variable attenuator 3 attenuates the signal s2 according to a signal s13. A time constant circuit 14 integrates an output of the detector 11 and a computing element 15 adds outputs of the time constant circuit 14 and the latch circuit 13.

Title: Control device for combustion device
Inventor: USAMI TADASHI
IPC: F23N5/20
Filed: 1986-04-14
Abstract: PURPOSE:To improve the safety and decrease a fuel consumption by a method wherein a discriminating circuit causes an operation of a combustion device to be continued only when a counting time under a timer circuit is shorter than a reference time and in case that the counted time exceeds the reference time, the operation of the combustion device is immediately stopped. CONSTITUTION:A combustion control unit 4 performs a combustion by increasing an amount of combustion until a combustion temperature reaches to a set temperature T, and from the time when the combustion reaches a target temperature, it may continue an operation with the amount of combustion capable of maintaining the set temperature T. When a temperature sensor 3 senses the condition in which an indoor temperature T' reaches to the set temperature T, a timer circuit 7 starts to count a time, a sensed output of the temperature T' is inputted to a discriminating circuit 8 and the indoor temperature T' is not decreased lower than the set temperature T. When cold air enters the room and a decreasing of the indoor temperature T' is generated after times t2 and t4 are elapsed, the discriminating circuit 8 instructs to stop counting time to the timer circuit 7, the counting times t' and t'' are compared with the reference time (t). If the counting times t' and t'' are shorter than the reference time (t), an instructing signal for continuing an operation is generated in an operation control device 5. In case that the counting time t' exceeds the reference time (t), an operation stop signal is generated to operate an alarm unit 9.
