Abstract: PURPOSE:To produce an Al alloy material having superior wear resistance and durability by locally melting the surface of an Al alloy base material contg. a specified amt. of B, Si or Ge together with a metal fed from the outside of the base material to form a hard alloyed layer. CONSTITUTION:Powder 3 of one or more kinds of metals such as Mi, Mn and Ti or hard particles of one or more kinds of compds. such as TiC, ZrN and Al2O3 is embedded in a shallow groove 2 cut in the surface of an Al alloy base material 1 contg. 1-30wt.%, in total, of one or more among B, Si and Ge. The surface of the base material 1 is locally melted together with the powder 3 by irradiation with laser beams 4. Since the wettability of a crystallized Al-contg. intermetallic compd. or the hard particles is improved by the B, Si and Ge, the intermetallic compd. or the hard particles are dispersed and alloyed with the Al matrix to form a hard alloyed layer 5 in the surface of the base material 1 in one body. An Al alloy material having superior wear resistance, not causing exfoliation under high surface pressure and capable of ensuring satisfactory durability is obtd.

Title: Gas turbine stationary blade structure and life controlling method therefor
Inventor: ISOBE NOBUHIRO
IPC: F01D9/02
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To suppress maximum crack growth of a gas turbine stationary blade and to attain long lives of parts by preliminarily providing cooling holes on paths of cracks for a portion in which growth of the cracks is estimated and making a structure in which stress strength at tips of the cracks is reduced at a point of time when the cracks reach the cooling holes. SOLUTION: When thermal fatigue cracks 3 are detected in a gas turbine stationary blade, development of the cracks 3 is suppressed by working holes 4 in the growth directions of the cracks 3 and reducing specific stress field at tips of the cracks 3 when the cracks 3 reach the holes 4. Because the shapes of the holes 4 reduce stress concentration in the growth directions of the cracks 3, the holes 4 are made elliptical or race track type holes in which the growth directions of the cracks 3 become a minor axis. Because there are many cases where portions generating these thermal fatigue cracks 3 can be estimated from a structural analysis or analysis of trends of past damage data, sometimes these holes 4 are preliminarily worked at a portion where the cracks 3 are estimated to be generated when manufactured.

Title: Image forming device
Inventor: TANAKA YOSHIAKI
IPC: G03G21/00
Filed: 1990-11-09
Abstract: PURPOSE:To reduce irregular state caused by a specific winding of a photosensitive belt and prevent reduction in image quality such as mis-transfer or the like by a method wherein the photosensitive belt is intermittently moved during an interrupted state of printing. CONSTITUTION:After a transfer sheet 12 is discharged, if a next printing instruction from a controller is not outputted even after elapsing of a predetermined time T or more set by a timer, a photosensitive member driving motor is driven only for a specified period of time (t) without having any relation with the printing instruction and if the printing instruction is not outputted even after the predetermined time T elapses after driving operation, similar driving is carried out by a control part. In this case, a driving length of the photosensitive belt 14 under a specified period of time (t) is shorter than a driving time of one circumference of the photosensitive belt 14. Accordingly, an entire photosensitive belt 14 can always be kept at a uniform stressed state, thereby peculiar winding states of rollers 40 to 42 generated at the photosensitive belt 14 is reduced and image quality can be improved.

The roller 74 is then rotated backward to draw the yarn 1 into the drawing tube 7 and thereafter, the yarn is drawn into a lamella 21 and the drawing tube 72 and the roller 74 is displaced toward 74a to open the yarn 1.  The yarn is then inserted to the reed 4 via a guide 60 which is the drawing element of the reed 4.

Abstract: PURPOSE:To improve the rotational efficiency of paper sheets and to shorten a transaction time by counting up the number of overlapped paper sheets by a number detecting part and treating the counted paper sheets as discharging paper sheets. CONSTITUTION:Paper money stored in a composite cash cassette 7 or a cash cassette 8 is separated by a separating part 3 and carried to a payment port part 5 through the number detecting part 4. The number detecting part 4 for finding out the number of superposed sheets of money by measuring the thickness of the money is provided with three pairs of number detecting cams 11b rotating in the direction of the arrow B and number detecting sensors 12b. After counting up the number of sheets of money by the detecting part 4, whether the sum of the counter number and the number of sheets stacked on the payment port part 5 coincides with the regulated number of sheets to be discharged or not is checked by the detecting part 4 to discharge the regulated number of sheets of the money. When the sum is more than the prescribed number, the money is discharged from a recovery carried part 6 to a reject part 7a of the cassette 7 and separated and carried again. Consequently, the rotational efficiency of paper sheets can be improved and the transaction time can be shortened.
