Title: Manufacture of semiconductor device
Inventor: NISHIMURA HIDETAROU
IPC: H01L29/78
Filed: 1983-03-31
Abstract: PURPOSE:To simplify the steps by implanting multiatomic ions obtained by ionizing a boron-containing substance in the boundary between a semiconductor layer and a metal layer, then heat treating it to react the metal layer with intermetallic compound and forming a P type region on the surface, thereby forming a low resistance semiconductor region. CONSTITUTION:Mo is, for example, accumulated on the overall surface of an insulating wall 6 formed in the previous step to form an Mo layer 7. Then, BF2 is implanted so that the implanting peak is disposed in the boundary between the substrate 1 and the layer 7, thereby mixing the boundary between the substrate 1 and the layer 7, and the boundary between the pattern 4 and the layer 7. Then, when a heat treatment is performed, silicide is produced between the substrate 1 and the layer 7, and between the pattern 4 and the layer 7, MoSi2 layers 81, 82 as intermetallic semiconductor compound layer are formed between the substrate 1 and the layer 7, and an MoSi2 layer 9 is formed between the pattern 4 and the layer 7, and a gate electrode 10 made of the pattern 4 and the lay layer 7 is formed. Simultaneously, the boron implanted with ion so that the peak is disposed in the boundary between the substrate 1 and the layer 7 is activated on the substrate surface to form p<+> type source and drain regions 11, 12.

Title: Manufacture of rare earth magnet
Inventor: SHIOBARA YUKIHIKO
IPC: B22F1/02
Filed: 1986-03-14
Abstract: PURPOSE:To realize long term storage under the powder condition and improve productivity by executing metal plating in the thickness of 0.1mum-1.0mum to the rare earth metal powder. CONSTITUTION:The basic composition includes rare earth metals such as neodium (Nd), Praseodium (Pr), Celium (Ce) or Dysprosium (Dy) and iron (Fe), cobalt (Co) and boron (B). At least one kind of metal plating is executed to the rare earth magnetic powder in the thickness of 0.1mum-1.0mum and it is then molded and sintered by the powder metallurgical method. As the metal to be used for metal plating, any kind of metal which is more diffcult to be oxidized than the rare earth metal included in the rare earth magnetic powder can be used. If thickness of plating is under 0.1mum, it is also probable that the plating is not perfect. When thickness exceeds 1.0mum, magnetic performance is drastically lowered due to the mixture of impurity. Therefore it is desirable that the thickness is selected to such range.

Abstract: A powder dispensing assembly (10) including an elongated chute (34) having opposite ends (40) pivotally supported for rotation about a pivot axis (38) within an elongated housing (20) and having a funnel-shaped cross-section with a wide upper portion (42) and a narrow lower portion. A dispensing platform (26) is integral with the rear wall (46) of the chute (34) and extends forwardly beneath the front wall (44) and slopes upwardly to a lip (28) over which particles of powder move to define a falling curtain of powder particles. A supply platform (30) is supported just above the pivot axis (38) and receives powder from an elongated slot (32) and supplies powder to the dispensing platform (26) as the powder falls downwardly through the chute (34). The supply platform (30) is wider than the angle of repose of the powder supplied thereto so that when the supply platform is not moving powder is not being supplied to the lower dispensing platform (26). An electromagnet (80) co-operates with a spring plate (66) which is, in turn, connected by a rod (58) through the housing to the rear wall (46) of the chute (34). The electromagnet (80) operates on 60 cycle AC and, when energised, sets up a magnetic field to bend the spring plate (66) to rotate the chute (34) in a counter-clockwise direction about its pivot axis (38) and between cycles the spring plate (66) springs back and returns the chute (34) by rotating it in the clockwise direction. The upper supply platform (30), therefore, rocks about the pivot axis (38) to supply powder to the lower dispensing platform (26), the supply of powder from the supply platform (30) being less than the capacity of the dispensing platform (26).

Title: Image recognition method
Inventor: KATSURA YOSHIHIKO
IPC: H04N1/46
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To quickly extract the shape of a measured object by calculating the density difference between a part corresponding to the measured object and its peripheral part in regard to the kernel component images of the red, green and blue images respectively and using the kernel component image having the largest density difference to extract the edge of the measured object. SOLUTION: A color image FCR is separated into the component images and the noise components are eliminates. Then the density difference of every component image is calculated along a scanning line L crossing the outer fringe of an image pattern TP that is obtained by photographing a measured object T. In other words, the density differences CR, CG and CB of the R, G and B images are calculated respectively. These differences CR, CG and CB are compared with each other and the component image having the largest density difference is used to extract the edge of the object T. Thus, it is possible to quickly extract even the border line of an object that cannot be extracted with its monochromatic image since the density difference of this image cannot be calculated.

Abstract: PROBLEM TO BE SOLVED: To make it possible to attain mutual joining, by welding, of metallic porous members useful for component members for a metal mold for resin molding and casting, a filtering apparatus, etc. SOLUTION: This metallic porous member is a composite body prepared by subjecting a porous metallic sintered compact layer and a pore-free metallic member layer to solid state bonding, and further, mutual joining of the above members can be done by welding via the pore-free metallic layer part. The metallic composite porous member can be produced by laminatedly sealing a metal powder to be the porous metallic sintered compact layer and a pore-free metallic member to be the pore-free metallic member layer in a capsule, applying hot isostatic pressing sintering treatment (HIP) at low temp. under low pressure, applying, if necessary, heat treatment (for strengthening the bonding of grains of the sintered compact and the mutual solid state bonding between the sintered compact and the metallic member) after HIP treatment, and then removing the capsule.  Further, a composite body, in which the use of the metallic member is omitted and a part of the capsule is allowed to remain in the capsule-removing stage after the treatment and the resultant remaining part is used instead of the pore-free metallic layer, can also be obtained.
