Patent KR-860001199-B1 (KR)
Title: Color television signal modulating circuit
Inventor: SAKAI TETSUROO
IPC: H04N11/20
Filed: 1983-03-19
Granted: 1986-08-25
Abstract: The converter for NTSC-standard signal to a PAL-standard signal, or vice versa, operates with an NTSC signal in which an auxiliary carrier of two colour components in quadrature are modulated on a PAL signal of similar modulation. The signal components in quadrature modulation are modulated on an auxiliary carrier. A signal generator provides a first continous signal wave with a differential frequency and a second signal wave with summation frequency. Two modulated signals are generated by multiplication of original signal with first signal wave, and by multiplication of the original signal with the second signal wave respectively.

Title: Control signal generating circuit of magnetic record reproducing apparatus
Inventor: DOKUYAMA YOSHIO
IPC: H04N5/7826
Filed: 1984-04-20
Granted: 1989-04-10
Abstract: This circuit acquires a simple controlling pulse of a flipflop, a mono-multi gate circuit and is easily made to an IC and provides a cheap controlling circuit.  In a helical scanning small VTR, while recording, this one records an image signal in a magnetic tape, and at the same time records a control pulse which is acquired by dividing a vertical synchronizing signal (60Hz) to 2 parts in the individual track which is called as an image signal track.  Comparing a sampling pulse with a large pulse reference signal, this circuit acquires a phase-comparing error signal and controls the capstern to a regular verosity by a phase-comparing error signal.

Title: Method for controlling expansion of a tube within a tube sheet
Inventor: FINCH CURTIS L
IPC: B21D39/08
Filed: 1984-09-24
Granted: 1985-12-28
Abstract: The system for repairing tubes in high pressure steam generating installations, employs a mass or volumn pump. Fluid pressure is applied from the reservoir and the expander supply tube (20). The system pressure and rate of pressure increase are monitored under computor control as a function of incremental changes in oil volume or mass. A decrease in the rate is indicative of the onset of expansion of the plastic sleeve. Pressure increase continues until the change rate of pressure decreases again, indicating the onset of the plastic yielding to the tube.

Because of the stretching, the passage of the gas is improved and a uniform, finely dispersed gas bubble formation is produced. For clearing the perforated membranes of blockages of the perforations, the streteched state of the membranes is briefly released and subsequently again reproduced. For strong impurities, the gas supply is interrupted, the membranes are exhausted of gas and water, the stretched state is subsequently released and, after a predetermined time, gas is again fed into the perforated membranes and then the stretched state is reproduced.
