Patent JP-H11134706-A (JP)
Title: Optical pickup device
Inventor: AKIYAMA HIROSHI
IPC: G11B7/14
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To record/reproduce/erase excellently information on/from both optical recording media by irradiating luminous flux from a first and a second light sources with wavelengths different from each other on a first and a second optical recording media whose substrates each has a thickness different from each other through a first and a second light source coupling lenses and a common objective lens. SOLUTION: Laser luminous fluxes with light emission wavelengths different from each other from the first/second light sources 11/12 are made parallel luminous flux through respective optical path separation means 21/22 and respective coupling lenses 31/32 for light source. These respective luminous fluxes are converged on a recording surface of set thin/thick optical recording media 7/8 as a light spot by a common beam splitter 4, a polarizing prism 5 and the objective lens 6. These respective reflected luminous fluxes are received by first/second return luminous flux receiving parts 91/92 through reverse paths, and focus, track error signals and a regenerative signal are obtained from these respective light receiving areas. Thus, the deterioration in the wavefront aberration of the light spot due to the optical axis deviation of the objective lens 6 is suppressed, and an excellent characteristic is obtained.

Title: Inspection method of semiconductor device
Inventor: IKEGAMI GORO
IPC: H01L21/66
Filed: 1985-12-27
Abstract: PURPOSE:To simplify work, and to measure the thickness of solder precisely by a method wherein a dummy pellet treated so that a back electrode is easy to be peeled in used, the dummy pellet is mounted onto a substrate by solder and peeled and the thickness of the solder remaining on the substrate is measured. CONSTITUTION:With a dummy pellet 1, an Ni layer 3 and a Ni oxide layer 4 are laminated and formed on the back side of a chip such as an silicon chip 2 on succession, and a gold or silver back electrode layer 5 is shaped onto the Ni oxide layer 4. The back electrode layer 5 has excellent affinity to solder, but the Ni oxide layer 4 has inferior adhesive properties to gold and silver as the back electrode layer 5. Consequently, when the dummy pellet 1 is mounted onto a substrate 6, such as a lead frame, a stem or the like by using solder 7 and the dummy pellet 1 is picked up by forceps, etc., the pellet 1 can easily be peeled, leaving the back electrode layer. Since the thickness of the back electrode layer 5 is made extremely thinner than that of the solder layer 7 and can be ignored, the thickness (t) of solder 7 is measured by a known device, such as an air micrometer, a laser interferometer or the like from the upper section of the back electrode layer 5.

Title: Methanol reforming catalyst
Inventor: TSUKUDA IWAO
IPC: B01J23/755
Filed: 1991-11-14
Abstract: PURPOSE:To obtain an excellent catalyst having long life and showing high activity and high selectivity in reaction producing hydrogen-containing gas using methanol or a liquid mixture of methanol and water at low temp. by adding oxide of one or more kind of a metal selected from copper, zinc and chromium and nickel oxide to zirconia. CONSTITUTION:A methanol reforming catalyst is obtained by adding oxide of one or more kind of a metal selected from copper, zinc and chromium and nickel oxide to zirconia. This catalyst may be used as it is but, since reduction reaction due to methanol is suddenly advanced at the time of the supply of methanol and the possibility of the deterioration of the catalyst is high, it is pref. to preliminarily reduce the catalyst. Reduction operation is performed by heating the catalyst in a reductive gaseous atmosphere of hydrogen, carbon monoxide or a gaseous mixture of them or by reducing the catalyst with hydrogen and carbon monoxide formed by decomposition/reforming reaction bringing methanol or a mixture of methanol and water diluted with inert gas into contact with the heated catalyst.

Title: Oil supply tank device
Inventor: WATANABE ISAO
IPC: F23K5/14
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent an oil supply port cap from being tightened more than necessary. SOLUTION: A corrugated plate 19 having elastic ridges and troughs is mounted at a knob handle 12 side in a predetermined direction at an engaging part of the handle 12 with an elevation guide cylinder 13. Thus, the engaging relation between the plate 19 and guide ribs 15 of the cylinder 13 is freely movable in an axial direction of the cylinder 13 of the handle 12. When a rotary force for tightening the oil supply port cap 13 is operated by the handle 12, the plate 19 of the handle 12 is brought into contact with the rib 15. If the specified or more force is applied in this case, a sliding sound is generated between both so that tightening more than necessary may not be conducted. Meanwhile, when a rotary force of a direction for removing the cap 3 is exerted, the plate 19 is brought into contact with the rib 15, and the cap 3 can be removed effectively.

Inventor: YOKOYAMA HARUHIKO
IPC: H04N5/378
Filed: 1992-11-10
Abstract: PURPOSE:To measure a node of an interference fringes with high accuracy by dividing a picture element density of a CCD light receiving element forming an interference fringe pattern into two series being odd number and even number orders whose contrast tendency is opposite to each other, approximating them in straight lines and using a cross point of two straight lines as a node of the interference fringes pattern. CONSTITUTION:An interference fringes pattern is outputted to a CCD light receiving element when rays whose pitch is slightly different from a pitch of CCD light receiving elements and forming a parallel contrast stripe pattern forming a long stripe 6 at a reference position is made incident in a CCD. Then the picture element density of the CCD light receiving elements is divided into two series being odd number and even number orders whose contrast tendency is opposite to each other, and the picture element density is approximated in straight lines. Thus, a coordinate of a node 14 based on a loop position of interference fringes corresponding to a long stripe 6 using a cross point 10 between approximated straight lines 8, 9 as a node of an interference stripe pattern is measured with high accuracy independently of the width of the interference fringes and the pitch or the like.
