IPC: H04L7/08
Filed: 1990-09-12
Abstract: PURPOSE:To prevent taking a long time for recovering synchronism even when a data train is shifted in a synchronous state by transmitting a reset signal from a first or second synchronizing part turned to the synchronous state first to the correspondent second or first synchronizing part so that the counter side can be asynchronous. CONSTITUTION:A synchronizing bit detection circuit 2 is provided to detect the synchronizing bit of an input signal, and first and second synchronizing parts 10 and 11 are provided to detect coincidence/non-coincidence between the synchronizing bit and a generated frame synchronizing pulse and to change the frame synchronizing pulse while counting the front and rear protection of the detected signal. The first or second synchronizing part 10 or 11 turned to the synchronous state first transmits the reset signal to the correspondent second or first synchronizing part 11 or 11 so that the counter side can be asynchronous. Thus, even when one coincidence/non-coincidence detection circuit, 4b detects coincidence while another coincidence/non-coincidence detection circuit 4a executes front protection, rear protection is started, by which time from out-of-synchronism to the recovery of synchronism can be shortened.

The droplet is placed on a focus of lens systems 5, 6, to form a distinct image onto a CCD camera. A physical edge of the outline is decided by deciding the reference luminance (the maximum available luminance), and then calculating the luminance point corresponding to about 25% of the reference luminance, when the outline is decided on the basis of the obtained droplet image. The volume of the droplet is calculated on the basis of the circle or ellipse droplet model of the droplet, after the outline of the droplet and the transporting member 4 is decided. Thereby even the droplet of less than 1μl can be correctly measured.
