Title: Release bearing mechanism for clutch
Inventor: TAKEUCHI YASUSHI
IPC: F16D25/08
Filed: 1986-04-18
Abstract: PURPOSE:To easily disassemble a lever plate from a wedge collar, by forming an elastic deformation part in the radial direction in the wedge collar and deforming said elastic deformation part to the inner in the radial direction. CONSTITUTION:When a device is placed in an operative condition, a wedge collar 21 is held between an inner ring 23 and a lever plate 22 by fitting an engaging groove 35 of the inner ring 23 in a release bearing 20 to a fitting part 36 of the wedge collar 21. Accordingly, the device is actuated with no generation of the elastic deformation. In the time of disassembly, first the wedge collar 21 is moved against a spring plate 30 approaching to the lever plate 22, and the fitting part 36 of the wedge collar 21 is deformed to the outside in the radial direction. Accordingly, the wedge collar is disengaged from the groove 35 of the inner ring, and under this condition, the inner ring 23 is drawn out to the outer in the axial direction. In this way, the wedge collar 21 can be deformed to the inner in the radial direction, and a ring member can be disassembled. Further the wedge collar, which forms a slit 44 in the elastic part, is easily deformed.

Title: Pre-column derivation method and device
Inventor: TANAKA HIROYUKI
IPC: G01N30/74
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To broaden the sample selection by performing the introduction and reaction of a reaction reagent with a sample, the delivery of the sample, the trapping of a sample band, and the delivery of the trapped sample to an analyzing device in different processes. SOLUTION: When a solvent containing a derivation reagent is carried from a pump 1, and a sample is fed from an injector 2, they reaches a reactor 4 through a 6-way valve 3, where the reagent reacts with the sample. The 6-way valve 3 is switched to carry the solvent from a second pump 5 to the reactor 4 and carry a sample band to a first column 10, and the sample is trapped in the first column 10. When the 6-way valve 3 is then switched, the solvent from the pump 1 and the solvent from the second pump 5 are discharged from drains 6, 11 through the reactor 4 and the first column 10, respectively, and the sample band is trapped in the first column 10. When an analyzing eluant is inputted by a third pump 9, the sample trapped in the first column 10 is sent to a second column 12 and detected by a detector 13.

Title: Apparatus for inspecting unburned western style closet
Inventor: YAMAMOTO YOSHIHARU
IPC: G01B21/20
Filed: 1989-04-11
Abstract: PURPOSE:To prevent the breakdown of a closet during measuring by providing moving and energyzing members beneath a part between pad parts which are in contact with the unburned closet and a block which is moved up and down, lowering the block part, and detecting the moved amount after the contact of the pad parts and the closet. CONSTITUTION:A movable block 50 is guided, lowered and moved through guide shaft 48 and 48 by the lowering of a rod 46a of a cylinder 46. During the lowering movement, shafts 64, 66 and 68 corresponding to pad parts 70, 72 and 74 come into contact with the specified positions of the unburned closet which is a material to be measured. Then, only the movable block 50 is lowered. Coil springs 76, 78 and 80 are compressed. The shafts 64, 66 and 68 are relatively moved upward with respect to the movable block 50. The amounts of movements are detected with encoders 82, 84 and 86. Thus the breakdown of the unburned closet whose strength is weak can be prevented without applying excessive measuring pressure on the closet.
