Title: Method of protecting pressure fluidized bed boiler
Inventor: NAKAMURA SHINOBU
IPC: F22B1/02
Filed: 1992-06-23
Abstract: PURPOSE:To protect a fluidized fed boiler from damage due to trouble with a gas turbine and facilitate resuming its operation by permitting air to flow into the boiler from a pressure vessel through a cutoff valve to reduce the difference in pressure between the inside and outside of the boiler. CONSTITUTION:An inside part of a pressure vessel 1 and an inside part of a boiler body 3 communicate with each other by a bypass pipe 12 and then combustion air at high pressure flows from the pressure vessel 1 directly to a combustion part 14 inside the boiler body 3. The bypassing pipe 12 is provided with a cutoff valve 15 for use in shutting off the flow of combustion air. During a normal operation, the cutoff valve 15 is closed to shut off the air flow. On the other hand, when a gas turbine 18 is stopped suddenly, the cutoff valve 15 is opened to cause the combustion air to flow from the pressure vessel 1 to the inside part of the combustion part 14 of the boiler body 3. With such an arrangement above, in the case that the gas turbine is stopped suddenly due to its trouble and the like, a differential pressure within the boiler can be rapidly eliminated.

Title: Transmitting device for digital signal
Inventor: SAWAGATA KIYOSHI
IPC: G11B20/14
Filed: 1986-07-14
Abstract: PURPOSE:To surely prevent the generation of pseudo clocks at the reception side by counting the changing points within a prescribed period of a digital signal and adding information on the changing points to a preamble period after channel-coding it. CONSTITUTION:An encoder 2 codes the digital information signal of a terminal 1 through channel-coding and supplies it to an addition circuit 4 via a delay circuit 3. While the clock of a terminal 6 and the synchronizing pulse of a terminal 10 are inputted to a changing point counting circuit 9. Then the number of changing points are counted within a clock period. An encoder 11 codes the information on the number of changing points through channel-coding where pseudo clocks are not easily produced and adds the coded information to a preamble period via the circuit 4. At the reception side the oscillation frequency is corrected when no coincidence is obtained between the number of changing points within a clock period and those added. In such a way, the generation of pseudo clocks is surely prevented.

Abstract: PURPOSE:To form a film or sheet in uniform thickness by a method wherein a picture of a resin heap accumulated between first calender rolls is produced by thermograph and the area ratio of a portion corresponding to the resin in the picture is calculated and the amount of a bank is kept constant by controlling the material supply to the bank or the basis of the value of the area ratio. CONSTITUTION:A picture of a resin heap accumulated between first calender rolls 1 is produced by thermographs 3, 4 and 5 so as to calculate the area ratio of a portion 8 corresponding to the resin in the picture. Under the condition that the amount of a bank at which the most favorable result has been obtained is set, the area ratio is calculated and memorized. After that, the area ratio is calculated every fixed period so as to obtain a variation in order to adjust the rotation of the screw of a kneading device 6 in response to the variation. In case that the bank 2 increases, the value of the area ratio also increases and the delivery of the kneading device 6 is decreased in proportion to the increase. By the method as mentioned above, a film or sheet with uniform thickness or little fluctuation in thickness was obtained.
