Patent JP-H02231122-A (JP)
Title: Detection of vent of vent extruder
Inventor: TAKEUCHI KUNIO
IPC: B29C48/76
Filed: 1989-03-03
Abstract: PURPOSE:To prevent deterioration in detection response properties, since molten resin is not solidified even if the same is stuck to a temperature detecting sensor by detecting vent-up and taking treatment such as an alarm or a change of an operation condition, by a method wherein the inside of a deaerating part of a vent extruder is heat-controlled at a temperature higher than a molten resin temperature and a detecting temperature of a temperature sensor for vent-up detection provided within the deaerating part is declined. CONSTITUTION:Molten resin on the inside of a cylinder 2 is transferred to the left from the right by a screw 3 and a jacket 4 is controlled at a higher temperature than that of molten resin by a temperature sensor 5. A temperature sensor 6 for vent-up detection detects a temperature of a vent part 8. When vent-up is generated, raised molten resin 9 comes into contact with a tip detecting part. A vent-up detecting signal is sent out by detecting that a detecting temperature of the temperature sensor 6 is declined lower than that of the vent part and instructions such as an alarm or a change of an operation condition are issued. Since the vent part 8 is kept heated at the melting temperature of the resin or higher, even if the molten resin is stuck to a detecting part of the tip of the temperature sensor 6, the stuck resin is not solidified and detection response properties are not deteriorated.

Title: Production system of reception control signal
Inventor: NONAKA KENJI
IPC: H04L25/40
Filed: 1984-03-19
Abstract: PURPOSE:To obtain a general-purpose generating circuit for reception control signal by using a guard bit having the pattern width corresponding to the transmission speed of a transmission signal as a start bit and therefore producing a reception control signal corresponding to the transmission speed. CONSTITUTION:The pulse width of a guard bit of an output (a) of a photoelectric converter 40 is converted into a number of clock pulses. In other words, the state change of the input pulse is detected by delay type flip-flops 21-1 and 21-2 and a gate 26. A counter 22 is reset by the output Q of the flip-flop 21-2 and then counts clock pulses. A pulse C which detects the fall of the guard bit by a fall detecting circuit 27 is applied to a terminal L of a latch circuit 23. The clock count value of a period corresponding to the guard bit width of the counter 22 is shifted as it is to the circuit 23. A gate 28 extracts the value of the counter 22 via a decider 29 when the count value of the counter 22 exceeds the prescribed level and performs an AND operation with a signal (c). Then a set/ reset type flip-flop 30 is set, and the output CD of the terminal Q is used as a reception control signal.

IPC: D21C11/12
Filed: 1986-03-11
Abstract: PURPOSE:To make it possible to automatically adjust a heavy oil fuel to a predeter mined base value after a load change by gradually returning the charge quantity of the heavy oil fuel to a charge quantity thereof before the time of a load variation after the setting of the load variation, and outputting a control signal to increase or decrease a black liquid in a calory quantity meeting the calory of varying heavy oil and to change the same. CONSTITUTION:In the case of increasing a load, when the load reaches a predetermined value, an output signal from a signal selector 14 becomes one from a heavy oil base signal setter 16 by an output signal from a monitor 17. However, a signal representing a value adjusted so that a deviation value from a comparator 15 is not abrupt by changed is outputted by a change rate limiter 18, and an adjusting signal based thereon is outputted from a heavy oil flow quantity base adjusting meter 19 and inputted to an adder 23. The adjusting signal is added to a signal of a black liquid flow quan tity calculated from a main vapor flow quantity, and is adjusted so that it falls within a predetermined range, and inputted to a comparator 11 as a signal representing a set value of the black liquid flow quantity. For this reason, the black liquid flow quantity slowly increases, and the flow quantity of the heavy oil fuel is reduced until it becomes a heavy oil base value in accordance with the increase of the black liquid flow quantity.
