Title: Machining method by means of laser beams
Inventor: UMETSU KAZUNARI
IPC: H01L21/3065
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To improve machining accuracy by irradiating a base material with circularly polarized laser beams and thereby preventing a through-hole from being bent and deformed. SOLUTION: When laser beams are linearly polarized, an anticipative hole is bent and deformed. The reason is that, when the beams are incident on the inner wall with P-polarization, the light absorptivity of the base material is greater as compared to incidence with S-polarization, thereby promoting machining. Once the hole is non-uniformly machined, the non-uniformity is furthered by the light guiding effect of the through-hole. In the case where laser beams are circularly polarized or converted to random polarization, non-uniformity of S- and P-polarization is eliminated; otherwise, random irradiation of S- and P-polarization suppresses bending of the through-hole.  It is desirable that a protective film is formed on the base material, with laser beams radiated to it through the film, that the protective film is formed on the front and the rear face of the base material, that the substrate is a silicon signal crystal substrate with a (100) or (110) surface, and that the anticipative hole is formed with laser beams and expanded by anisotropic etching.

The whole of them is adhered onto a cover glass 5 by the same adhesive 2, and the adhesive is hardened at a normal temperature for >=20hr. After hardening and adhesion are completed, they are set to a tensile test machine and are fixed by upper and lower chucks, and measurement is performed in 100mm./min tensile speed. Thus, samples whose adhesive strength cannot be evaluated conventionally are measured, and production of samples is easy, and the reproducibility is good, and therefore, this method is very useful.

Abstract: PROBLEM TO BE SOLVED: To make a bladder of an inexpensive material and to simplify its structure by forming an orifice hole in the bladder for dividing a shell empty chamber into a port flow-in chamber and an orifice flow-in chamber, the orifice hole being for communicating both chambers. SOLUTION: An empty chamber 5 in a shell 2 is divided into an orifice flow-in chamber 19 and a port flow-in chamber 20 by a bladder 14 and an orifice hole 18 for communicating the orifice flow-in chamber 19 and the port flow-in chamber 20 to each other is formed in the bladder 14.

Filed: 1994-02-22
Abstract: PURPOSE:To recover recorded data even when it is erased by an erroneous operation by using recording time data as managing data in a system for initializing data only on a managing area. CONSTITUTION:A CPU 5 sequentially reads recording time data (a) from a head block in a voice data area, reserves it in a work area A of a memory 3, and examines whether values of the data (a) are all '0' or not. Then, if all, the data (a) are not '0', it is compared with a value of recording time data (b) reserved in a work area B. When the value of the data (a) represents new time as compared with the value of the data (b), a content of the work area A is written in the work area B and a work area C for reserving managing data, and '1' is added to a number-of-reading counter D. An address of next recording starting block is calculated from the value of the counter D, the recording time data and the calculated address in the area C are written in a managing area of a recording medium, thereby recovering an erroneous erasing.

Filed: 1986-03-05
Abstract: PURPOSE:To reduce the deviation of an optical axis at the fixing of an optical fiber with a lens, to attain fixing with high strength and to obtain stable and highly efficient coupling by unitedly fixing the optical fiber with the lens through a holder and inserting and arranging the holder in a groove of a fixing board fixed on a base. CONSTITUTION:An optical waveguide 5 is optically coupled with the optical fiber 4 through a prism 2 pressed and fixed on an optical waveguide 5 formed on the board 1 and the lens 3 fixed to the optical fiber 4. The optical fiber and the lens 3 are unitedly fixed through the holder 8, the holder 8 is inserted and arranged in the groove of the fixing board 9 fixed on the surface of the base 1 and the side walls of the groove are fixed with both the side parts of the holder 8. when the light input/output surface 2a of the prism 2 is plane, the surface 2a is formed almost vertical to the optical axis. It is especially preferably to use a self-converging lens or a spherical lens as the lens 3. Since resin is not used between the prism 2 and the lens 3, the deviation of the optical axis due to the contraction/expansion of the resin at the hardening and fixing of the resin can be suppressed and highly efficient coupling can be easily obtained.
