Title: External synchronizing circuit
Inventor: NITTA KEIICHI
IPC: H04N5/073
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To decide uniquely the phase relation between an input SYN signal and an output video signal from a D/A converter at all times by configuring a frequency divider circuit contained in the multiplex D/A converter circuit so as to be included in a PLL circuit consisting of a synchronizing separator circuit, an LPF and a VCO. SOLUTION: An input SYNC signal from an input terminal 100 is separated into HD and VD. The HD signal is given to an input terminal A of a phase comparator 102. The comparator 102 provides an output of a phase difference between output signals from input terminals A, B and the output is given to a VCO 104 via an LPF 103. An output frequency of the VCO 104 is changed by an input voltage. The output from the VCO 104 is given to a D/A converter 108, in which the signal from the VCO 104 is frequency-divided and the resulting signal is given to a decode circuit 106. The circuit 106 provides an output of a read clock and a control signal or the like for a memory circuit 107 and a signal equivalent to a horizontal synchronizing signal HD at the input terminal B of the phase comparator 102 is outputted. Thus, the PLL circuit is configured as above.

Title: Line terminal equipment
Inventor: OISHI YOSHIKATSU
IPC: H04M11/00
Filed: 1990-01-29
Abstract: PURPOSE:To reduce considerably power consumption of a battery and to make the size of the battery small and to reduce the capacity by supplying power supply at communication between a line terminal equipment and a data communication terminal equipment from a telephone line. CONSTITUTION:When a line terminal equipment 2 is in standby state, a battery power 23 is applied only to a control section 26. When a call request comes from a data terminal equipment 3 to the control section 26, the control section 26 closes a DC circuit switching section 21 to apply power voltage from a telephone set 1 to the line terminal equipment 2 and supplies power also to the data terminal equipment 3. The data terminal equipment 3 uses the power to make communication to a call destination via the line terminal equipment 2 and the control section 26 opens the DC circuit switching section 21 after the end of communication and restores to the standby state. Thus, since the battery in the line terminal equipment is used only for the auxiliary power supply in the standby state, the current consumption is reduced considerably and the battery is made small in size and small in the capacity.
