Title: Batch control system
Inventor: NATSUME AKINORI
IPC: G05B7/02
Filed: 1985-03-22
Abstract: PURPOSE:To improve the convergence of a controlled variable and to converge it to a set value speedily by making the command of a control signal larger than the set value on the start of batch control and increasing a flow rate temporarily, and then performing feedback control. CONSTITUTION:Piping XY has a pump P and a control valve V in its middle and the flow rate in the piping is controlled by a batch controller C and the valve V. The valve V is fully closed before the start of the batch control and the flow rate in the piping is zero. The control is so performed by the controller C and valve V so that the flow rate is a set flow rate on the start of the batch control, and the valve V is fully closed on the end of the batch control. The control signal CS is larger than the command R of the control signal at the start of the batch control, i.e. time t0 and a desired value A within <=100% is outputted, so that the flow rate approximates the set value, but the signal CS tracks the command R when the deviation of the flow rate from the set value decreases below a set deviation value at time t1, thereby starting the feedback control. The deviation is small at this time t1 and the signal CS is a signal suitable to the set value, so the signal CS and flow rate are settled under this control without oscillating.

Title: Assembling method for hydraulic shock-absorber
Inventor: WATANABE TORU
IPC: F16F9/52
Filed: 1986-03-14
Abstract: PURPOSE:To improve the assembling performance by inserting a sliding member into a path formed from the tip of a piston rod while communicating with a bypath to separate between the bypath and the temperature sensitive chamber while choking the open end of the temperature sensitive chamber with non- compressive packing and securing the packing with a nut.

Title: Pulse generating circuit
Inventor: SUMIYOSHI HAJIME
IPC: H04N9/455
Filed: 1987-03-13
Abstract: PURPOSE:To generate a stable gate pulse by comparing the level of a saw-tooth wave signal obtained from horizontal scanning reference pulses of a horizontal automatic frequency control circuit (horizontal AFC circuit) with the level of a reference DC signal and performing conversion into pulses, and delaying those pulses with a specific time constant, then shaping their waveform. CONSTITUTION:When a delay output signal DP is smaller than a reference voltage V1, the transistor(TR) Q10 of a voltage comparing circuit 181 turns on and a current flows to a resistance R7. Consequently, the base potential of a Q16 rises to an 'H' level and the Q16 turns on, so that the level at a gate pulse output terminal 19 goes down to an 'L' level. When the signal DP rises above the reference voltage V1, the Q16 turns off to the contrary and the potential at the output terminal 19 rises to the 'H' level. Consequently, the gate pulse GP synchronized with the period of a color burst signal Bu is obtained by setting a circuit constant properly. Consequently, the gate pulse which is stable in phase and pulse width is obtained as long as a horizontal AFC circuit is locked.

Abstract: PROBLEM TO BE SOLVED: To sufficiently prolong the service life of a light emitting element by suppressing the temperature of the light emitting element of an aviation trouble lamp, and also to downsize and make an aviation trouble lamp light- weight. SOLUTION: AC from a commercial power source 40 is full-wave rectified by a rectifying circuit 41. The full-wave rectified AC is switched by an FET 42. The current passing through the FET 42 is smoothed by a smoothing current 43. The smoothed current flows to an FET 4. The current flowing to the LED 4 is detected by a resistor 44. Based on this detection signal, a control signal generating circuit 45 supplies the FET 42 with a control signal, so that the current flowing to the LED 4 is substantially a prescribed current. The calorific value of a driver is reduced due to the switching action of the FET, whereby the temperature of the LED 4 can be suppressed.
