Title: Direct sheet rolling method from molten steel using large-diameter roll
Inventor: SEKINO AKIZOU
IPC: B22D11/06
Filed: 1978-12-01
Abstract: PURPOSE:To directly produce the sheet of superior quality from molten steel by cohering the molten steel on the surfaces of one set of the rolls having been internally cooled in a non-oxidizing atmosphere and compression-bonding and rolling two sheets one set of shells with the roll gap. CONSTITUTION:Molten steel is poured thrugh a nozzle 3 into the molten steel well 6 formed by twin rolls 9 of a diameter 1.5m or more and side walls 4, 8. This is so done that in a steady state the molten steel covers 1/4 or more of the peripheral length of the rolls 9. Cooling water of high velocity is flowed in the inside space 8 of the rolls 9. When the rolls 9 revolve and the molten steel makes contact with the surface 7, the molten steel deposits to form shells. The shells become gradually thicker and at the roll gap the shells on the right and left roll surfaces compression- bonded and rolled to a sheet 12. The sheet 12 is rolled by the rolling rolls 11 which are internally cooled and is then taken up. The entire process thereof is accomplished in a non-oxidizing atmosphere.

Title: Operation of circulating type fluidized bed boiler
Inventor: KONO MAKOTO
IPC: F22B1/02
Filed: 1987-06-16
Abstract: PURPOSE:To maintain combustion efficiency and desulfurizing reaction at high levels even under the lowered load by circulating back the circulation bed matter positively from the inside of a hot recycle to the inside of a combustor so that the differential pressure between neighborhood of the primary air outlet in the combustor and the outlet of the combustor may reach a fixed value. CONSTITUTION:A command of a positive flow back of the circulating bed matter from the inside of a hot recycle 18 to the inside of a combustor 1 is performed by a control system so that the differential pressure DELTAp between an outlet 12A of the primary feed pipe set within the combustor and an outlet 1A of a combustor 1 may become constant or a predetermined value for a load of the boiler. If the differential pressure DELTAp is less than the fixed value, an opening degree of a control valve 32 is increased. When the air G is jetted out of a nozzle 30 into a hot recycle pipe 5, a circulating bed matter R within the hot recycle 18 is routed back into the combustor 1, and a combustion efficiency and desulfurizing reaction within the combustor 1 are maintained at high levels. On the other hand, when the differential pressure DELTAp comes to a fixed value, the control valve 32 is shut to stop a flow back of the circulating bed matter R.

Title: Recording device
Inventor: HORI TAKESHI
IPC: G11B20/22
Filed: 1982-08-26
Abstract: PURPOSE:To compensate completely the time axis variation due to the traveling system of a recording medium, by detecting the speed variation of the recording medium to control a delay means which transmits an input signal. CONSTITUTION:The output of an oscillator 30 is applied to a speed signal recording head 26 and recorded on a magnetic tape 10. This recorded signal is read out by a speed signal reading head 28 and sent to an F/V converter 36 to be converted into the error voltage which represents the time axis variation. A pulse generator 38 produces a clock pulse having its frequency varied in response to the error voltage and sends the clock pulse to a delay circuit 40 through which the sound signal given from a sound signal source 42 passes. The clock pulse controls the sound signal in response to the time axis fluctuation of the tape 10. Then the output of the circuit 40 is sent to a recording head 24 and recorded on the tape 10. In such a way, the time axis variation due to the traveling system of a recording medium can be compensated completely.
