Title: Characteristic measuring base body for laser light and characteristic measuring method for laser light using same
Inventor: NODA MASANORI
IPC: B23K26/00
Filed: 1986-10-17
Abstract: PURPOSE:To measure the power density of laser light, its distribution, and irradiation position accuracy by forming an amorphous layer of the same material with a single crystal substrate on a single crystal substrate, and irradiating the amorphous layer with the laser light. CONSTITUTION:A characteristic measuring base body 1 for the laser light is constituted by forming the amorphous Si layer 3 on the single crystal Si substrate 2. Then, a positioning mark 5 for finding the irradiation position of the laser light 4 is formed on the base body 1. The base body 1 is used to find a specific irradiation position determined with data based on the mark 5, and the substrate 2 is irradiated with the laser light 4 with such power that part of the substrate is fused. Then, a nearly semicircular fused area 6 corresponding to the density distribution of the laser power is formed in the Si layer 3 including the partial single crystal Si area 7 of the base body 1. The area 6 is recrystallized after the irradiation to form a single Si area 8 and a polycrystal Si area 9. The areas 8 and 9 are compared with each other to measure the power density of the laser light, its distribution, and irradiation position accuracy.

Title: Production of artificial bone head
Inventor: TOTSUGI KATSUTOSHI
IPC: A61F2/36
Filed: 1989-09-26
Abstract: PURPOSE:To obtain the artificial bone head having a bone head ball which is free from the chipping and microcraking from a juncture by subjecting the tapered part on the inside surface of the bone head ball consisting of ceramics to grinding, thereby working the part between the large-diameter part and opening end of the tapered part to a smoothly curved surface. CONSTITUTION:After the tapered part 3 of the bone head ball 2 is subjected to taper grinding on the inside surface, the shape thereof is arced or chamfered in such a manner that the tapered part 3 of a taper shape and the end edge 6 form the smoothly curved surface. The working to form the smoothly curved surface is executed by limiting the surface roughness to 0.4 to 0.05Ra. The end edge 6 and curved surface 7 of the tapered part 3 are smoothly connected when a tapered stem shaft 5 of a stem part 4 is fitted to the tapered part 3 of the bone head ball 2 of the artificial bone head 1. Since the curved surface 7 has a good surface, the chipping and microcracking hardly arise and, therefore, even if a vertical load is applied on the bone head ball 2, the excessive decrease in the strength at the end edge of the bone head is obviated and the load is eventually applied uniformly over the entire part of the tapered part 3. As a result, the strength is improved.

Filed: 1988-09-30
Abstract: PURPOSE:To decompose such a character string as a Japanese sentence, etc., that has no punctuation and has the finite length into paragraphs at a high speed by using a register which holds (stores temporarily) the character strings, the multiplexers interlocking with each other via a controller, a collator, etc. CONSTITUTION:A character string having no punctuation and to be studied is supplied to an input contact CHR IN and held by a register REG. Then the character blocks are prepared from the input character string by a fixed rule via the multiplexers MPX1-4 and a controller CONT. These character blocks are collated with each other by the collators DIC1-4 containing the electronic dictionaries. The satisfaction or dissatisfaction of the punctuation is decided based on the results of collation of the collators. In this case, the number of characters covering the head of the character string through the head of the character block is referred to as (i) with the number of characters of the character block referred to as (j). In such a case, only the character block that satisfies i=in+jn is defined as a subject of collation against in and jn which are suited to the contents of the dictionary when (i) is collated successively with 1 and subsequent numbers. Thus it is possible to decompose such a character string as a Japanese sentence, etc., that has no punctuation and has the finite length into paragraphs at a high speed.

Filed: 1988-09-30
Abstract: PURPOSE:To make possible the subdivision and recording of a main scan line image using optical element arrays by making the optical paths arranged adjacently of a SELFOC lens array different in length. CONSTITUTION:Optical element arrays 12A, 12B consists of linear light emitting sections 14A, 14B with many light emitting diodes or luminous intensity limiting elements arranged in a scan direction respectively. The optical element array forms partially scanned line images lxa, lxb in the scan direction on an optical writing surface 11 through SELFOC lens arrays 13A, 13B, if the array is driven in response to an image signal. In the meantime, an image is formed on the optical writing surface 11 by the movement of a recording medium with the optical writing surface 11 in a subscanning direction. However, the partially scanned line images lxa, lxb formed by the optical element arrays 12A, 12B are placed together at lox in the scanning direction and at a point away by loy from the subscanning direction. The misaligned images in these scanning lines are linearly corrected easily by delaying the generation time of a signal driving the optical element array. Consequently, the scanning line image is subdivided and recorded by optical element arrays.
