IPC: A01C11/02
Filed: 1993-10-29
Abstract: PURPOSE:To improve the performances of travel and work in the case of a work machine having more than four drive axles in the right and left directions of a machine body, by making constitution in which drive wheels on the outermost side conduct differential rotation and inside drive wheels also conduct differential rotation. CONSTITUTION:The differential lock device 10a of a first differential mechanism 10 is changed over by means of an operation lever to a non-operation state in which right and left rear wheel drive shafts 11, 11 are rotated differentially, and a differential lock operation state in which they are rotated integrally. Also, the differential lock device 13a of a second differential mechanism 13 is changed over to a non-operation state in which right and left axles 14'.14' are rotated differentially, and a differential lock operation state in which they are rotated integrally. As a result, at the time of setting young rice plants, proper rice planting work can be carried out by making the rotations of rear wheels 7a, 7b, 7c, 7d all the same. Meanwhile, at the time of a machine body being turned, differential lock devices 10a, 13a are changed over to the non-operation state, and right and left drive shafts 11.11 and right and left wheels 14'.14' are rotated differentially. That is, the outermost side drive rear wheels 7a, 7d are rotated differentially, and the inside drive rear wheels 7b, 7c also come to be rotated differentially.

Abstract: PURPOSE:To prevent the contact resistance of a contact hole from increasing or becoming unstable by proving an etching stopper film made of a metal or nitride which forms a volatile fluorine compound when it is exposed to fluorine gas plasma at the time of forming a contact hole. CONSTITUTION:After forming a wiring metallic film 3 of Al or an Al alloy on a semiconductor substrate 1 and a lower-layer wiring 3L by patterning the film 3, a layer insulating film 6 is formed. At the time of patterning for exposing the wiring 3L, an etching stopper film 4 made of a metal, such as tungsten, etc., or nitride which forms a volatile fluorine compound when the metal or nitride is exposed to the plasma of a gas containing fluorine is formed on the entire surface of the film 3 or selectively formed in the lower area of an interlayer contact hole 9. Then upper-layer Al wiring 10 is formed of Al-2% Cu alloy, etc., on the contact hole 9 formed by dry etching with a gas containing fluorine. Therefore, the deposit of the Al alloy, etc., which makes the contact resistance of the contact hole 9 to increase or unstable is not formed at the time of forming the hole 9.

Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To easily set border conditions by easily extracting the area to set the border conditions even in the case of a border condition setting area having a complicated shape. SOLUTION: A selection reference point P is set (step S31).

Filed: 1984-12-24
Abstract: PURPOSE:To take an accurate measurement not only in the atmosphere, but also under water by detecting the formation of a crank in a cut bottom from variations in interference between laser beams. CONSTITUTION:A test-piece 1 which has a cut 2 equipped with a beam splitter 3 and a reflecting mirror 4 is fixed to the piston 9 of a testing machine at one end and to the cross head 11 of the testing machine at the other end. Laser light from a laser light source 19 reaches the reflecting mirror 15 through a water tank 13 and then travels to the beam splitter 3 from it. One of branched laser light beams travels straight to reach the reflecting mirror 4 and the other reaches a reflecting mirror 16; and those reflected laser lights are emitted out of the water tank 13 through the beam splitter 3 again. In this case, those two laser light beams interfere with each other because of their difference in optical path and a detecting device 20 records an image of the state of this interference. The variation in the interference is made to correspond to the opening extent of the cut part 2 to detect the point of time when a crack is formed.

Title: Chelate resin
Inventor: MATSUDA KIMIAKI
IPC: B01J45/00
Filed: 1986-11-14
Abstract: PURPOSE:To obtain a chelate resin having excellent adsorption capacity and adsorption velocity, by incorporating an aminocarboxylic acid group into the structure of a chelate resin. CONSTITUTION:The title chelate resin contains an aminocarboxylic acid group of formula I, wherein X is hydrazine, polyalkylenepolyamine or a derivative thereof; n is 1-3; m is 1-6; M is a hydrogen atom, an alkali metal or an alkaline earth metal. The reason why the above-mentioned chelate resin has higher capacity and velocity of its adsorption onto metal ions is believed to be that the carboxylic acid group is bonded to the main chain of the polymer via a spacer of formula II, so that the polymer can readily form a coordinate bond which has a steric stability with the metal ion forming hydrated ions of a large radius in the aqueous solution, so that the adsorption capacity is increased, the that the spacer of formula II is a hydrophilic amido group, so that the hydrophilic property of the resin itself is enhanced, and eventually contributes to the improvement of the adsorption velocity.

Title: Breakdown preventing device for magnetic disk device
Inventor: NISHIDA SADAHIRO
IPC: G11B19/20
Filed: 1984-12-26
Abstract: PURPOSE:To prevent previously the breakdown of a magnetic disk device due to the adhesion between a magnetic head and a magnetic disk of the disk device applying a contact start-stop system, by detecting the adhesion of the head approximately at a time when the revolution of the disk is started. CONSTITUTION:A magnetic head 1 is attached to a magnetic head drive mechanism 3 via a thin plate spring member 2, and a microswitch 4 is attached at the tip of a support member 5 of the mechanism 3. If adhesion is caused between the head 1 and a magnetic disk 7 when the revolution of the disk 7 is started, the member 2 bends in the revolving direction of the disk 7. Thus the switch 4 is pushed by the head 1. Thus said adhesion is detected. A brake action is applied together with stoppage of the revolution of the disk 7. This prevents the injuries produced between the head 1 and the disk 7.

Filed: 1993-10-06
Abstract: PURPOSE:To obtain a slanting image in a document effective area by detecting an area where all the slanting output on a line overflow the document effective area, and masking an after-slanting area signal by an overflow area detection signal. CONSTITUTION:Input image data are written on a line buffer(LB) 15 for original image and an LB 16 for slanting image alternately via a line buffer control part 12. In a readout operation, original image data and slanting image data are read out from the LBs 15, 16. A slanting area arithmetic part 13 inputs designation area start/completion position signals MX1, MX2, and the overflow area detection signal OVER from a slanting address arithmetic part 11, and calculates a rectangular area MK1 to judge the area to which slanting processing is applied. Furthermore, the after-slanting area signal MK2 is calculated by slanting start/completion position signals MX1', MX2'. When the signal MK2 is calculated, it is masked by the signal OVER. Also, the position of the slanting image can be set at a wide range by changing an offset value in a main scanning direction.
