    摘要： A manufacturing method produces a liquid ejecting head including first and second flow path members having liquid flow paths that communicate with each other. An integrally-molded member is surrounds the second flow path member on the second flow path member side of the first flow path member to join the first and second flow path members together. A holding process defines a space portion for forming the integrally-molded member in a frame section. The frame section is brought into contact with a contact surface of a recessed portion in the face of the second flow path member opposite the first flow path member, with the first and second flow path members contacting each other such that the liquid flow paths communicate with each other. A molding process fills the space portion with resin, thereby molding the integrally-molded member, and joins the first and second flow path members together.

    摘要： The object of the invention is to provide a video switchover detection circuit that reduces the circuit scale and allows high-accuracy detection with a smaller-scale configuration.According to the invention, the video switchover detection circuit comprises a PLL circuit composed of a phase comparator, an LPF, a VCO, and a frequency divider. In the phase comparator, the phase of an external HD as an input signal obtained by shaping the pulse of a horizontal synchronization signal is compared with the phase of an internal HD as a reference signal obtained by dividing the frequency of the output pulse of the VCO in the PLL circuit. In case the phases of the signals differ from each other, an error signal is output from the phase comparator. A first counter counts the period in which the error signal is active, or the time when the phase difference persists. A horizontal synchronization decision section determines the lock state of the horizontal synchronization signal depending on the length of the phase difference duration and in case out of synchronization is detected, a video switchover detection signal is output from an output circuit.
