Title: Method and device for reporting pdu reception
Inventor: YAMASHITA HIROYUKI
IPC: H04L29/06
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To improve the throughput of a device by further speedily starting communication protocol processing, in comparison with the conventional method with which processing is started by reporting the reception/transfer of an entire communication protocol data unit(PDU) to a communication protocol processing means after the completion of that reception/transfer. SOLUTION: When a report completion flag F1 is turned on, the PDU is repeatedly transferred for each unit from a communication control means 51 to a communication data holding means 4 and at every time, an incrementer I1 updates the value of a transfer counter T1 just for one unit length worth. When the report completion flag F1 is turned off and a comparator C1 discriminates the contents in the transfer counter T1 becomes more than the contents in a report length register R1, it is reported to a communication protocol processing means 31, and the report completion flag F1 is turned on. At the time point when that report is received, the communication protocol processing means 31 starts the communication protocol processing.

Abstract: PROBLEM TO BE SOLVED: To provide a gas-liquid separator which can improve the efficiency in separating a gas from a liquid. SOLUTION: A spiral gutter is placed on the inner wall surface of the body of a gas-liquid separator which gives a distilling treatment to liquid wastes and separates the distilled water with low-level radioactivity and condensed liquid wastes. Then, a gas-liquid two-phase flow runs through an entrance nozzle 1 into the gas-liquid separator, collides with a collision plate 2 to be scattered and is strickers against the inner wall surface of the gas-liquid separator by centrifugal force. Thereafter, the flow is guided by the gutter 7 to slowly fall toward a liquid surface 4 while circling spirally, and droplets in the gas-liquid two-phase flow fall on the liquid surface 4. In the meantime, a gas phase rises toward an ascending cylinder 6 after it lowers near to the liquid surface 4. A demister is provided in the ascending cylinder 6.  A liquid phase contained in the gas phase is separated from it by colliding the rising gas phase with the demister 5.

Abstract: PURPOSE:To eliminate such troubles in transferring operation as transfer unevenness, transfer missing and transfer defect by providing an image forming body with a function sectional type photosensitive layer including phthalocyanine system pigments and transferring, fixing, circulating and conveying a color toner image on a transfer material as a part of a transfer material conveying stage. CONSTITUTION:A recording signal read from a color signal or a color original is outputted to a writing system B as a first color signal and a semiconductor laser beam modulated by the signal is written on the image forming body, on which an electrostatic latent image is formed. As carrier generating materials, versatile phthalocyanine system pigments which absorb the semiconductor laser beam, generate enough carriers and are little fatigued and degraded by the laser beam are specially used. A first color toner image is transferred and fixed on the transfer material fed from a paper feeding cassette corresponding to an image formation timing. A second color toner image formed on the image forming body based on a second color signal is transferred and fixed on top of the first color toner image. Thus image quality degradation due to transfer slurring, transfer unevenness etc., is eliminated, and a color image of proper quality is obtained.
