Abstract: PURPOSE:To effectively control the number of revolution of a fan for circulating a gas for recovering waste heat to a waste heat recovering installation by controlling the number of revolution of the fan in accordance with the actual number of revolution and electric power cost thereof. CONSTITUTION:The gas which is intensified in pressure by the fan 4 passes through the inside of sintered ore 5 in an upper stream side region trough 2a of a cooling machine 2 retaining the sensible heat after calcination. The gas is subjected to a heat exchange with the sintered ore 5 to form hot wind. The hot wind is fed to a boiler 6 where the hot wind is subjected to a heat exchange with water to generate steam and to form cold wind. The cold wind returns again to the fan 4. The signal for the actual number N of revolution of the fan 4 and motor 8 controlled by a number of revolution control device 9 obtd. from a speed generator 11 provided to the revolving shaft of an electric motor 8 of the fan 4 and the signal for the electric power cost L from a wattmeter 13 provided in a power source inlet from a power source 12 to the device 9 are inputted to an arithmetic unit 10. N<3>/L is calculated in the unit 10 and is compared with a reference value K. The result thereof is subjected to a coefft. processing by a constant (a) and is added to the reference number nk of revolution, from which the optimum number Nmax of revolution is determined and the number of revolution of the fan 4 is controlled.

Title: Sealing device
Inventor: KANZAKI YOSHIYUKI
IPC: F16J15/16
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent a leakage of sealing fluid at the time of rotation in both directions and event at stationary time by providing a lip slide part with a plurality of steps of annular abutting parts which form the maximum value of contact pressure distribution on a slide surface biased toward a sealing fluid side than to an atmospheric air side in the axial direction. SOLUTION: In a condition in which a slide surface to which a lip slide part 4a abutts turns, contact pressure distribution forms respective contract regions 4e the maximum contact pressure part Pa biased toward a sealing fluid side M of the contact region 4e. Since pressure gradient of fluid inlet part of the contact region 4e is large when sealing fluid flows out on an atmospheric air side O, a film thickness of sealing fluid which flows out to the atmospheric air slide O hydrodynamically is formed to be thin, and an amount of sealing fluid which flows out is reduced. The sealing fluid which flows out on the atmospheric air side is held between the contact regions 4e.  When this fluid returns to the sealing fluid side M on the contrary, however, a thickness of fluid film which flows in the sealing fluid M and returns increases and an amount of fluid which returns increases because pressure gradient of the fluid inlet part which corresponds to the atmospheric air side O of the contact region 4e is small.

Title: Production of magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/851
Filed: 1987-04-08
Abstract: PURPOSE:To uniformly obtain good C/N in high-density magnetic recording and reproducing at a high speed and to permit formation of a material for which there are heretofore no available mass production means to a thinner film by using a moving vapor deposited film to form a target at the time of forming a thin ferromagnetic metallic film by sputtering vapor deposition. CONSTITUTION:The endless target 14 is constituted of titanium foil or nonmagnetic stainless steel foil, etc., and deposited with the thin ferromagnetic metallic film by evaporation on the surface opposite to a high-polymer film 10. More specifically, the target 14 is constituted of the moving vapor deposited film at the time of forming the thin ferromagnetic metallic film by the sputtering vapor deposition on the moving substrate 10. Since the ferromagnetic part of the target is thin, an electromagnetic field for trapping electrons does not change and is strong and, therefore, uniform conditions are maintained and the higher speed is obtd. Since the constituting elements are merely required to be discretely controlled and taken into the vapor deposited film, even the material which cannot be worked to a sheet is usable as a sputtering target.

Title: Guide installation for conveyor belt
Inventor: KITA TSUTOMU
IPC: B65G15/08
Filed: 1995-03-17
Abstract: PURPOSE: To facilitate replacement works for a carrier guide with an outside pillow member eliminated in inclination, save labor, and shorten working hours by connecting a support device which can support the outside pillow member with its inclination angle changed, to the outside pillow member. CONSTITUTION: When a bar handle 27 is rotated upward, since the connecting pin of an upper side link 25 and a lower side link 26, which consist of a toggle link, is positioned close to a vertical line connecting the center line of a pressing bar 24 with a pivot 23 down below, the pressing bar 24 can powerfully support an outside pillow member 15. At this time, since the upper end of an auxiliary support 18 is located down below the mounting section of a hinge 16 at the outside pillow member 15, the inner end section of the outside pillow member 15 is prevented from being excessively lowered down. On the other hand, when the bar handle 27 is rotated downward, the pressing bar 24 is lowered down by two times as much as the link length of a lower link 26.  Therefore, if only the lower link 26 is appropriately set in length, the outside pillow member 15 can be fallen down roughly at a level, replacement works for a carrier guide 3 over the outside pillow member 15 can thereby be facilitated.

Since the coil spring 105 is fixed to the boss at one end to regulate the axial winding position, the winding number of the coil spring 105 around the drive gear 102 is set to the maximum value to maximize the allowable transmission torque of the torque transmission device 100, and because the coil spring 105 is fixed in the axial direction, the fluctuation of the allowable transmission torque is controlled.
