Title: Manufacture of silicon epitaxial wafer
Inventor: NAKAJIMA TAKASHI
IPC: H01L21/205
Filed: 1986-02-04
Abstract: PURPOSE:To obtain a silicon epitaxial wafer characterized by less defects, by including a process for forming oxygen depositing nucleuses having specified concentration distribution, and a process for epitaxially growing silicon. CONSTITUTION:Oxygen ions 6 are implanted in a silicon substrate 5. Heat treatment of only the surface layer of the silicon substrate 5 is performed by using laser or an electron beam 7. The distribution of atoms, which are implanted in the silicon substrate 5 is hardly changed. Only the oxygen atoms near the surface are expelled, and the oxygen concentration in the surface becomes low. Owing to the series of treatments, small oxygen depositing nucleuses can be formed in the silicon substrate 5. The concentration distribution in the thickness direction rises up rapidly from a certain depth. Therefore, the defect density when silicon is epitaxially grown on the silicon substrate 5 can be suppressed to a small degree. Thus the epitaxial layer having less defect is grown on the silicon substrate, and a silicon epitaxial wafer characterized by the less defects can be obtained.

IPC: H04N1/44
Filed: 1989-02-01
Abstract: PURPOSE:To prevent information transferred on facsimile recording paper from being read externally by adhering a security sheet onto the surface of the facsimile recording paper via an adhesion means. CONSTITUTION:A security sheet for facsimile recording paper is installed to a desired state so that the sheet is fed with facsimile recording paper simultaneously in a facsimile receiver and when an original is sent from a sender in this state, the security sheet 5 is supplied together with the facsimile recording paper and the security sheet 5 and the facsimile recording paper are discharged from the facsimile receiver while being adhered to each other via an adhering means provided to a sheet main body of the security sheet 5. In this case, since the security sheet 5 is adhered onto the surface of the facsimile recording paper, the information transferred to the facsimile recording paper is secured by the security sheet 5 and never read externally.

Title: Thread running device of sewing machine with needle fluctuating device
Inventor: HAYASHI MINORU
IPC: D05B3/02
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To avoid an increase in the manufacturing cost and the intensification of a noise without changing a driving source for a needle fluctuating device by reducing the number of parts to cut the cost to the minimum, allowable extent and smoothing the ascending action of an operating rod to make the sewing operation more reliable. SOLUTION: A stitching operation is performed by enabling a shaft 7 and an operating rod 10 to be fluctuated together with a needle bar 2 and fluctuating the needle bar 2 within a specified fluctuating range during a stitching operation to perform the stitching process without allowing a mechanism 10c for transmitting a power on the operating rod side to interfere with a mechanism 16 for transmitting a power on the driving source side. In a addition, both mechanisms 16, 10c are connected to each other by fluctuating the needle bar 2 to a specified fluctuating position outside the fluctuating range, and thereby the powder of the driving source 15 is transmitted to the operating rod 10 through the mechanism 16, 10c when the thread is run through a needle hole. Thus, the thread running operation is achieved by loweringand raising the operating rod 10.  This operating design makes it possible to provide the mechanism 10c for transmitting a power on the operating rod side, on the operating rod 10. Further, the operating design makes it possible to raise the operating rod 10 using the stronger power of the drive source 15 than an energizing force, and besides, makes it possible to avoid the mounting of the drive source 15 on a needle rod support frame.

Title: Master carrier for magnetic transfer and magnetic recording medium
Inventor: NAGAO MAKOTO
IPC: G11B5/86
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the servo operation of a slave medium from becoming inaccurate by forming the shapes of transfer patterns at foremost and rearmost parts of the preformat pattern to the prescribed shapes. SOLUTION: End surfaces of respective end parts of the patterns, positioned at both end parts in the tracking direction of patterns in the preformat region 2, that is, the foremost pattern 8 and the rearmost pattern 9, are inclined outward from the vertical line of the tracking direction. By this arrangement, the magnetic fields at the end parts of the preformat pattern region are formed in the direction oblique to the tracking direction at the time of transfer from the master carrier for magnetic transfer. The patterns at both end parts transferred to the slave are also deviated by the inclined angle θ accordingly. As the result, even though the undesirable magnetic information is generated from the end part of the preformat region, the influence to the actual servo operation is eliminated since the reproduced signal due to this information is further weakened.

Title: Primary layer penetration welding method by tig welding
Inventor: KUREISHI MASAYOSHI
IPC: B23K9/16
Filed: 1980-02-28
Abstract: PURPOSE: To obtain excellent welding results in TIG welding and pulse TIG welding and pulse TIG welding which do not use a backing strip in which a prescribed bead width and bead secctional area are obtained, by specifying setting of welding conditions.  
     CONSTITUTION: The sectional shape of a liquid existing between solids having a cpnstant thickness (h), is estimated by calculation from the theory of two-dimentional interface tension. In this case, mark + means plotted points showing BW and /A m  on the graph. The values, /H, BW, and /A are the values of thickness of solid (h), interval of solids b w , and sectional area of liquid A m  transformed into dimension-less values by the capillary tube constant (2σ/ρ g ) 0.5  (ρ;σ; density of liquid; surface tension, (g); gravitational acceleration) which shows the property of liquid. When interval of solids B w  is constant, the upper and lower surfaces of liquid show extremely concaved shape when amount of liquid /A m  is small. As amount of liquid /A m  increases, the lower surface of liquid becomes convexed shape from flat surface and the upper surface becomes flat. These calculation results are applicable to the bead sectional shapes of penetration welding.

Abstract: PURPOSE:To effectively transmit from a facsimile equipment exclusively used for the A5 size to the facsimile equipment exclusively used for the A4 size or more by previously dividing a RAM so as to have 1728 bits for respective lines, and previously writing a white picture signal in all the bits. CONSTITUTION:Picture data of 'white' is stored in all the bits of the RAM 3. From the leading bit of one line on the RAM 3 of 'white', the binarized picture data is overwritten successively. When coming to the 1,152-th bits, if one page is not completed, the picture data is stored in the RAM 3 by moving to the leading bit of the next line. Thereby, in the one line, in the bit above the number of all the bits of the one line used for the A5 size, all the 'white' data is stored. Accordingly, an original can be transmitted to the facsimile equipment for the A4 size or more from the facsimile equipment exclusively used for the A5 size.
