Title: Production of polymer
Inventor: HAYASHI TAKAOMI
IPC: C08G63/87
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To efficiently produce a polymer by subjecting a ring-opening polymerizable cyclic monomer to a ring-opening polymerization using a polymerization initiator especially not having a problem on production and handling, never containing a metal component, and not leaving an odor. SOLUTION: This method for producing a polymer comprises subjecting a ring-opening polymerizable four to eight-membered cyclic monomer (for example, a lactone such as β-propiolactone, a lactide such as a glycolide, or a cyclic carbonate such as ethylene carbonate) to a ring-opening polymerization in the presence of tris[tris(dimethylamino)phosphoranylidenamino]phosphine oxide and/or an active hydrogen compound (for example, water, a 1-6C carboxylic acid, a 1-10C alcohol, a 2-10C polyhydric alcohol having two to four hydroxyl groups or a 6-8C aromatic hydroxy compound). The ring-opening polymerization is carried out usually at 0-250 deg.C at <=3.0 MPa within 100 hr, preferably at 20-200 deg.C at 0.01-1.5 MPa for 0.1-50 hr.

Inventor: SUZUKI KATSUHARU
IPC: B28B3/02
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To remove the influence of the lamination and elastic post-effect of an extrusion molding by a method wherein a body from an extrusion molder is placed in a bottom mold, the side walls of which have open parts, and pressed through the lowering of a top mold so as to obtain a primary molded matter, thereafter, some part of the body is flowed outside the bottom mold at the pressing with the top mold so as to form excess clay parts, which are separated from the primary molded matter at its raising. SOLUTION: At a primary press 24, a body B placed on a bottom mold 34 is molded under pressure through the lowering of a ram 32 and a top mold 32. In this case, the bottom mold 34 comprises a vertically movable bottom surface body on a bottom part and side walls having fine horizontal slit-like opening parts. At the pressing of the body B with the primary molding press 24, some part of the body B is discharged through the openings as excess clay parts D outside a primary molding mold 30. By raising a primary molded matter C in the bottom mold 34 at the finishing of the molding of the primary molded object C, the excess clay parts D molded in the periphery of the molded matter C are separated from the periphery of the molded object C.  Thus, the finishing without the removal marks of the excess clay parts D can be realized, the influence of the lamination and elastic aftereffect left in the body can be removed and the deformation, strain and crack due to the uneven shrinkage of the body can be suppressed.

Title: Electronic analysis apparatus and method for object to be inspected
Inventor: YAU WAI FUN
IPC: G01B9/02
Filed: 1988-12-06
Abstract: PURPOSE: To obtain a method and device for performing nondestruction inspection by generating two images that are shifted in the side direction of a specimen and causing them to interfere each other. CONSTITUTION: A laser 11 applies light to an object 13 and reflection light passes through an optical system consisting of a birefringence means 15, a lens 17, a polarizer 19 and is focused on the image surface of an image sensor 21. The birefringence means 15 splits beams into two unparallel beams so that there are two special beams that are in parallel after passing through the means 15. Therefore, this sort of reflection light beams 25 and 27 become beams that are nearly in parallel but are polarized in vertical direction after passing through the means 15. Then, each beam is decomposed into constituents that are polarized in a different direction by 45 deg. from an original polarization direction by a polarizer 19 and becomes a pair of parallel beams that are polarized in the same direction. Then, an interference pattern can be obtained on the image sensor 21 due to the interference of the parallel beams. The interference pattern is equivalent to the overlapping of an image obtained by clipping a specimen and the deformation of the specimen can be observed by analyzing the inference pattern by a computer 23.

Title: Ignition timing controller for internal combustion engine
Inventor: MIYAMOTO KATSUHIKO
IPC: F02P5/15
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To accurately control the ignition timing regardless of the retrieval position for the fundamental ignition timing. SOLUTION: In a controller when the fundamental ignition timing is calculated by a fundamental ignition timing calculating means 21 in between a crank angle nearly corresponding to the intake-valve closing timing and a prescribed crank angle determining the ignition timing, a forbidding means 25 forbids an ignition timing means 22 to make compensative acceleration of the ignition timing, in determining the ignition timing by an ignition timing determining means 23. When compensative acceleration is unnecessary, overcompensation is forbidden in order to exercise accurate ignition timing control regardless of the retrieval position for the fundamental ignition timing.

Abstract: PURPOSE:To suppress shift shock always optimally by furnishing a sensing means to sense the running resistance of a car, and providing a drop amount correcting means, which decreases the drop of engine output caused by an output drop control means when an increase in the running resistance is sensed. CONSTITUTION:A control unit U1 for speed change energizes or deenergizes solenoids 5, 6 on the basis of a predetermined characteristic, to perform speed change and lockup control, and at the time of speed change, an angle delay demand signal M for delaying the angle of ignition timing is emitted fro a certain period of time in order to drop the engine output in principle to an ignition timing control unit U2. When receiving this signal M, the control unit U2 delays the ignition timing in all cases for a certain specified amount in the condition of two-wheel driving in principle, and a smaller amount then at two-wheel driving in the condition of four-wheel driving. When the angle delay amount at speed changing is calculated in accordance with the drive resistance in this manner, the ignition timing is corrected with this angle delay amount, and ignition control is performed so as to provided corrected ignition timing.
