IPC: B01D53/18
Filed: 1987-03-31
Abstract: PURPOSE:To efficiently remove SOX and HCl in exhaust gas, by successively passing exhaust gas through a first spray region using Mg(OH)2 and a second spray region using NaOH. CONSTITUTION:Exhaust gas is sent to a first absorbing tower 1 from a conduit 5 and the Mg(OH)2 absorbing solution sent from the first alkali agent storage tank 3 and recirculated is sprayed to the exhaust gas to absorb and remove HCl and SOX. At this time, since SOX is not absorbed too much, the exhaust gas is sent to a second absorbing tower 2 through a duct 7 and the NaOH absorbing solution sent from the second alkali agent storage tank 4 and recirculated is sprayed to the exhaust gas to absorb and remove the residual SOX. At this time, the injection amount of NaOH can be also controlled on the basis of the concn. of SOX discharged from the absorbing tower 2.

Title: Optical recording medium
Inventor: NAGINO KUNIHISA
IPC: G11B7/254
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce degradation caused by repeated overwriting and to obtain a superior overwriting shelf characteristic by providing at least a first dielectric layer/a recording layer/a second dielectric layer/a reflection layer on a substrate and also providing a layer which is mainly made of carbon between the recording layer and the first dielectric layer. SOLUTION: A carbon film is provided between a first layer dielectric and a recording layer, so that the adverse effect caused by elastic and plastic deformation of the first dielectric layer is reduced and worsening of jitters caused by repeated overwriting and decrease in the amplitudes of reproduced signals are prevented. Moreover, by providing the carbon film, changes in the state of atomic arrays and reaction between the dielectric and the recording layers are prevented even though the layers are left for a long time. Thus, degradation in the jitter characteristic by an overwriting shelf is improved. Considering the optical conditions, it is desirable to set the thickness of the carbon film between 0.5 nm and 10 nm so that the film hardly peels off from the first dielectric layer.

Abstract: PURPOSE:To minimize effect of temperature, non-linear characteristics and other characteristics related to the measuring accuracy by correcting outputs of a Hall  element based on the non-linear and temperature characteristics thereof stored  in a memory device. CONSTITUTION:A current Io flowing through a conductor 1 produces a magnetic field B in a core 2 which creates a magnetic field in a gap 3 developing a Hall voltage at terminals 7 and 8 of a Hall element 4. On the other hand, receiving request for interruption from an oscillator 16, a computing circuit 17 reads a Hall voltage V1 and the temperature of the Hall element 4 and calculates a magnetic field Be from non-linear characteristic of the Hall element stored in a memory device 14 while a magnetic field Bg actually generated in the gap 3 from the temperature characteristics and the temperature of the element 4. The measured current Io is calculated from the magnetic Bg and dimensions of the core 2 and outputted to a current display 18, thereby ensuring the measurement of current with limited measuring errors and a high reliability.

Abstract: PURPOSE: To provide an apparatus for feeding sheet-like products to a print processing device, which has high processing capability and which can be used in general purpose. CONSTITUTION: A conveying device 10 is composed of a plurality of clamps 12 which are linked to a rotary member, respectively, through the intermediary of a link member 66 and a carrier arm 30 whose rotating position is controlled by a first slot-like guide passage 34, and further, the position of the link member 66 is controlled by a second slot-like guide passage 42. With this arrangement, the clamps 12 can be rotated, independent from the movement of the carrier arm 30, and accordingly, the clamps 12 can grip products each time when they pass through a feed-out position, and accordingly, carry the products onto a transfer zone 20 where they discharge the products into a processing device. In particular, the speed of the clamps 12 can be changed while the speed of the rotary member is set to be constant, and further, the directions of the clamps 12 can be controlled independently.

Filed: 1980-06-16
Abstract: PURPOSE: To enhance a pump efficiency by preventing the water flow turbulence through straight- ening the flow in conformance with the out-going water flow angle while dividing a straightening vane in a water sending side into more than one water flow straightening pieces and also making each straightening piece or each straightening piece column in the side of the rotating vane to be capable of moving.  
     CONSTITUTION: If an operation rod 16 is operated in the direction shown by an arrow A, each frontal straightening piece 9 slants in the direction of the arrow A', and each rear straightening piece 10 makes a slanting motion in the direction of the arrow A" by means of each connecting plate 12 and 13, connecting rod 14 and a connecting rod 15. In this case, the straightening piece 10 is added momentum by the amount of θ/2 in addn. to the slanting angle of θ of the straightening piece 9. Similarly, if the operation rod 16 is operated in a direction of an arrow B, each  straightening piece 9 and 10 makes a slanting motion of the predetermined value in the direction of an arrow B' and B" respectively, to form a row of the straightening piece. Thus by this  mechanism, a straightening effect in accordance with the water flow angle which is sent out by a  rotating vane 6 can be obtained by using the row of the straightening pieces made of each piece 9  and 10, hence, the separation or the collision of the flow can be prevented.
