Title: Digital transmission system of television synchronizing signal
Inventor: UCHIUMI KUNIAKI
IPC: H04N5/04
Filed: 1982-08-09
Abstract: PURPOSE:To convert effectively a video signal into a digital signal and to transmit a synchronizing signal in the same transmission speed as the transmission of the video signal only, by transmitting two kinds of synchronizing signal at the blanking period of the video signal with a specific code different from each other. CONSTITUTION:The video signal to an input terminal T1 is converted into a parallel digital signal by an A/D converter 2 at the transmission side, a vertical drive signal is applied to a code converter 12 from an input terminal T7, and a horizontal drive signal is applied to a code converter 13 from an input terminal T8. Further, the converter 13 to the synchronizing signal to be given for the priority is connected in series to the post-stage. On the other hand, a receiving signal is converted into a digital signal at a serial/parallel converter 4 at the receiving side. Further, a lost accurate period is restored at a logical circuit 18 by giving the priority to the synchronizing signal. The code corresponding to the synchronizing signal is converted into a specific code and an output at a terminal T5 is made processable easily before the data of the video signal is D/A-converted with serial code converters 16, 17.

Filed: 1987-06-05
Abstract: PURPOSE:To contrive the stabilization of the frequency switching by applying setting change to a frequency division data in a frequency divider and to a preset voltage of a D/A converter synchronously based on a pulse timing of a reference signal.

Title: Flow controller for flow-through blower
Inventor: ITOU SHIYOUTAROU
IPC: F04D27/00
Filed: 1981-09-04
Abstract: PURPOSE:To effect quiet operation of a blower without electrically produced noise by continuously varying flow rate by control of electric power for a heater provided on a rear guider. CONSTITUTION:As a flow-through impeller 2 is driven at a constant number of revolutions n with a variable resistor 10 set for power value W1 for the heater 8, upward air current is produced as indicated by the arrow C near the heater 8 as the heater 8 warms up. therefore, fluid becomes hard to flow through the impeller 2 near the heater 8 so that the static pressure PS-flow rate Q characteristic becomes lower as compared with a characteristic under the heater 8 turned off. In this way, the flow rate Q can continuously be varied whereby no electrically produced noise can be generated because of continuous variation of electric power W for the heater 8 by means of the variable resistor 10.
