IPC: B65G53/56
Filed: 1985-05-29
Abstract: PURPOSE:To make a piping layout in front nd in the rear of a distributor designable freely and easily, a partioning off a chamber into both upper and lower parts with a permeable partition plate, while setting an inlet flow velocity from the upside and a columnar superficial linear velocity in an upper chmber independently each. CONSTITUTION:A chamber is partitioned off into an upper part 5 and a lower part 6 with a partition plate 4 making gas alone pass through. A solid-gas 2-phase flow setting a weight ratio between particled material and gas down to less than 15 at an inflow pipe 7 from the upside is led into the upper chamber 5. On the other hand, an air flow is passed through an inflow pipe 9 and a hole of the partition plate 4 and a columnar superificial linear velocity inside the upper chamber is kept at 1.0-3.0m/s and it is led into the chamber. If, so, since the solid-gas 2-phase flow into the upper chamber 5 is downward but the air flow from the hole of the partition plate 4 is upward, a solid-gas 2-phase fluidized state is kept intact so that a mixture flows out of an outflow pipe 8 in the same quantity at uniform concentration. With this constitution, it is effective for transport distribution, and a pulverulent body in extensive particled diameters is uniformly distributable and, what is more, a design and a degree of freedom from the operational standpoint are made larger owing to the independent setting of inlet flow velocity and columnar superficial linear velocity each.

Title: Data recording method of facsimile equipment
Inventor: IGAWA KAZUHIKO
IPC: H04N1/17
Filed: 1982-06-30
Abstract: PURPOSE:To prevent deterioration in the quality of a received picture resulting from overlap writing, white, etc., of received data on receiving paper by varying the timing of recording to receiving paper according to output intervals of a print request signal. CONSTITUTION:A reception part 1 decodes data on every line from a transmitting facsimile equipment through a circuit L to generate recording data DR, and generates the print request signal PQ every time one-line data is decoded. A control circuit 2 stores said data DR and sends a movement command signal PR to a motor driving part 3 at the same timing with the print request signal PQ. The delay time (t) from the starting of a stepping motor 5 to the movement of the receiving paper varies with intervals T of said signal PQ, so the control circuit 2 outputs the recording data DR to a recording element driving part 4 said delay time (t) after the output timing of the movement command signal PR.
