IPC: G11B15/61
Filed: 1988-04-12
Abstract: PURPOSE:To enable the stable tape traveling by providing a tape idling surface of a rotary drum with grooves which are approximately parallel to a lead of a fixed drum. CONSTITUTION:A magnetic tape 7 drawn out of a magnetic tape cassette is wound to a rotary drum device equipped with the rotary drum 1 and the fixed drum 4 at a prescribed contact angle, and the recording and reproducing of a signal are performed by a magnetic head. Then, the rotary drum 1 is incorporated with the magnetic head 3 which is protruded by a prescribed amt. from a window part 2 on its outer peripheral surface, while the outer peripheral surface of the rotary drum 1 is provided with plural grooves 6 approximately parallel to the lead 5. Thus, a force for sucking the magnetic tape 7 in the same height onto the rotary drum 1 is constant, so that the magnetic tape 7 is guided by the lead 5 without shifting toward a rotary shaft 8 of the rotary drum 1. By this method, the stable tape traveling can be performed, while the magnetic tape can be prevented from flawing, and wow and flutter can be reduced as well.

Title: Gas container cock
Inventor: SUMINOE TOSHIHIKO
IPC: F16K17/34
Filed: 1983-05-23
Abstract: PURPOSE:To keep the rate of flow in operation nearly constant and prevent a large amount of gas from being released at the breakage of a pipe, by providing a pressure- responsive member for a safety valve unit and providing an excessive flow prevention valve, which is actuated when the safety valve unit is put into operation. CONSTITUTION:When the pressure of gas in a container 7 has changed due to a pipe breakage or the like, a pressure-responsive member 25 acts depnding on the gas pressure and a spring 29. If the gas pressure is normal or low, the protrusion 26 of the member 25 projects in contact with the top of an upper suspension support 17 so that an excessive flow prevention valve 26 does not ascend and the working fluid is increased. If the gas pressure is abnormally high, the pressure exceeds the force of the sprong 29 to put a safety valve unit 24 into operation. At that time, the gas is released from discharge ports 22, 28a, the pressure-responsive member 25 is moved leftward, its protrusion goes off the top of the support 17, and the excessive flow prevention valve 14 is lifted into operation to hold down the flow rate of the working fluid. After a gas passage 11 is shut, a handle 1 is turned to push down the protrusion 15 of the valve 14 by a valve 4 to return a valve spindle 16 to its normal position and then return the member 25 to its normal position.

Abstract: PURPOSE:To lower the error of coal ash estimation by fluorescent x-ray analysis by computing the coal ash quantity from content of each component obtained by fluorescent x-ray analysis based on a specified equation. CONSTITUTION:Coal is pulverized and a binder is added thereto and press- forming is carried out to give a briquette specimen. X-ray intensity for Si, AQ, P, Ti, Ca, Mg, Fe, Mn, and S is measured by carrying out fluorescent x-ray analysis for the specimen. Based on the working curve at zero intensity of fluorescent x-ray at the time when no element exists, said working curve is set previously based on the x-ray intensity for each element, the content of each component of SiO2, Al2O3, P2O5, TiO2, CaO, MgO, Fe2O3, MnO, and total S is obtained by conversion. The coal ash quantity is computed from the content of each component based on the equation wherein A4=1.116, B4=0.945, C3=1.819, D3= 0.791, E3=0.944, F1=0.546, J4=0.141.
