Title: Method for determining end point of flattening in chemical mechanical polishing
Inventor: UIRIAMU JIYOOZEFU KOOTO
IPC: H01L21/3105
Filed: 1993-10-13
Abstract: PURPOSE: To eliminate a loss due to excessive polishing and reduce the manufacturing time, by using a moat surrounding an island having a metallic pattern thereon. CONSTITUTION: A substrate 36 is covered with a first insulating layer 38. A moat 44 that surrounds an island 50 is formed in the insulating layer 38. Metallic patterns 40 and 42 are formed on the insulating layer 38. The metallic patterns 40 and 42 are covered conformably with a second insulating layer 52. After an integrated circuit 30 is formed, the insulating layer 52 is polished chemically and mechanically to planarize the upper face of a chip region 32. In this case, an insulated part of the metallic pattern 42 is abraded faster than an upper part of the metallic pattern 40 of the insulating layer 52. The chemical mechanical polishing is continued until the upper part of the metallic pattern 42 is completely removed. The part of the chip region 32 of the insulating layer 52 is polished and planarized.  Then, monitoring for ending the chemical mechanical polishing can be carried out visually.

Title: Admixture for fiber-reinforced concrete
Inventor: YAMAGUCHI ZENJI
IPC: C04B16/02
Filed: 1988-10-11
Abstract: PURPOSE:To obtain an admixture for improving processability and quality of fiber-reinforced concrete by containing hydroxyethyl cellulose as an active component and specifying the hydroxyethyl molar substitution degree and viscosity of an aqueous solution thereof. CONSTITUTION:An admixture containing hydroxyethyl cellulose with 0.5-10 hydroxyethyl molar substitution degree and 1000-8000cP (20 deg.C) viscosity of a 1% aqueous solution thereof as an active component. If the viscosity (20 deg.C) of the 1% aqueous solution of the hydroxyethyl cellulose is lower than 1000cP, delaying action on cement hardening is great and demolding cannot be carried out or deformation of the extrusion molded product or cracking is caused in autoclave or steam curing. Furthermore, fiber dispersibility or impartment of plasticity tends to decrease. On the other hand, if the viscosity is higher than 8000cP, production of the hydroxyethyl cellulose itself tends to be difficult and the admixture is practically unusable.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To surely detect by preventing erroneous functioning in detecting a wave reflector. SOLUTION: A radar sensor detects the position of a wave reflector according to the reflection intensity of a wave from a lane marker 11 embedded on the road surface 12. Wave is emitted by an antenna 13 having a fan beam type directional characteristics 14 so that the longitudinal direction of the emission area 15 of an antenna beam coincides the band lane marker 1 and the width fits and reflected wave is received. By this, the ratio of reflection wave from the road surface 12 and reception level, S/C ratio is improved and lane markers 11 can be surely detected. If an antenna with the fan beam type directional characteristics having an antenna beam emission area perpendicularly crossing in the longitudinal direction of the antenna beam emission area 15 is used together, then more effective discrimination can be done.

Title: Medium, method, and device for hologram recording, and hologram recording and reproducing device
Inventor: MIZUNO SHINICHI
IPC: G02B6/13
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To reduce crosstalk between pixels by laminating optical waveguides in layers and laminating optical waveguide holograms, which use waveguide lights of the respective waveguides as reference lights and light waves made incident on the waveguide surfaces as object lights, in layers. SOLUTION: A waveguide hologram as a principal part of the hologram recording medium uses an evanescent wave generated on the surface of a waveguide as a reference light and a light wave made incident on the optical waveguide surface as an object light. A multirecording hologram is structured by laminating N waveguide holograms which are equal in refractive index between the substrates and clad layers. Consequently, an arbitrary hologram can be selected and reproduced by the irradiation of an optical system. Namely, the laser light from the semiconductor laser 23 is collimated by a lens 24, deflected by a galvanometer mirror 25, and converged on a waveguide end surface by a cylindrical lens 26. The light is made incident on the laminate type waveguide hologram 27 and diffracted by the holograms to generate a reproduction light 28.  Then a hologram to be reproduced is selected by adjusting the angle of the galvanometer mirror 25.

Title: Device for controlling engine
Inventor: SHIICHI HIROYASU
IPC: F02D45/00
Filed: 1988-10-12
Abstract: PURPOSE:To prevent the unnecessary erasing of memory at the time of a ordinary operation and surely erase memory only when necessary by erasing the contents of a backup memory in a control portion at the time of inputting information which is normally not inputted into the control portion. CONSTITUTION:As the failure of any of sensors is detected by a microcomputer 45, this is stored by a failure diagnosis memory and externally read out and indicated by a certain operation and the failure is repaired. Then, since there is need for erasing the contents of the memory, the ON/OFF of a switch 51 is carried out to apply a voltage 5V of a DC power source 49 for (n) times to the microcomputer 45 via an input terminal 50 and an A/D converter 47. Thereby, the content erasing condition of the failure diagnosis memory is established and the erasing is actually carried out. In this case, since the active voltage of an O2 sensor 31 is 0-1V and the switch 51 is totally out of use at the time of an ordinary operation, there is no fear of erroneous operation without unnecessarily erasing the stored contents of the failure diagnosis memory and other memories and timers.

Filed: 1990-09-26
Abstract: PURPOSE:To accurately position a slider at an image reading position and to prevent excessive load from acting on a driving mechanism by moving the slider in a return direction and making it abut on a stopper at the time of a planning copying mode. CONSTITUTION:The stopper 61 on which the slider 6 is made to abut and which regulates the position thereof at the time of the planning copying mode is provided.

Title: Apparatus for computing position of vehicle
Inventor: ANZAI YOICHIRO
IPC: G09B29/10
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To precisely calculate the position of a vehicle by a method wherein the estimated position of the vehicle by a self-contained navigation operation is corrected on the basis of coordinate data on a detected road marker (a magnetic nail or the like). SOLUTION: A vehicle-position estimation means estimates the position of a vehicle by a self-contained navigation operation. That is to say, an estimated- position computing part 14 computes an estimated position on the basis of a running-distance detection signal and a running-direction detection signal which are output from a running-distance detection part 11 (a wheel speed sensor or the like) and a running-direction detection part 12 (a gyro or the like). A magnetic-nail detection part 13 detects the magnetic field of a magnetic nail which is buried in a road, and a magnetic-nail-coordinate-data memory 15 stores the coordinate data train of the magnetic nail.  A position coordinate part 16 computes the relative distance between the magnetic nail and the vehicle, the relative distance is compared with coordinate data on the magnetic nail, and the estimated position which is computed by the estimated-position computing part 14 is corrected. In this manner, the position, of the vehicle, which is estimated by the autonomous navigation operation is corrected.
