Title: Vehicle lateral speed detecting device
Inventor: FUKADA YOSHIKI
IPC: B62D6/00
Filed: 1994-01-24
Abstract: PURPOSE:To suppress the accuracy reduction of the vehicle lateral speed owing to an integration error of a sensor value, by detecting the actual vehicle lateral speed by correcting the time integration value of the value subtracting the lateral acceleration from the product of a yaw rate and a vehicle longitudinal speed, by the logical laterial speed in case of assuming a two freedom plane model. CONSTITUTION:By detecting Gy, theta, and Vx by sensors 20 to 24, and by integrating (gamma.Vx-Gy) by a computer 30, the actual lateral speed Vy is operated. On the other hand, a sensor 26 detects the actual steering angle delta, and the computer 30 operates a logical lateral speed VYM in case of assuming that the vehicle in a normal circular turning condition under a two freedom plane model, depending on the delta and Vx. And by correcting the Vy by the VyM, the final Vy is found, and by dividing the Vy by the Vx, the slippage angle beta at the center of gravity of the vehicle is found. Furthermore, the friction coefficient mu of the road surface is inferred by the relation of the slippage angle beta and the tire lateral force F.

Title: Method and apparatus for purifying sludge substance
Inventor: SHIBAZAKI MITSUHIRO
IPC: C02F1/24
Filed: 1995-01-19
Abstract: PURPOSE: To increase flotation speed and to make sludge substance removing work efficient by ejecting fine air bubbles to bond them to a sludge substance to raise the sludge substance before ejecting air bubbles having a relatively large diameter. CONSTITUTION: High pressure air is supplied to the air sump 2 of an air bubble generator 7 from a compressor through an air pipe to be ejected into the water of a passage 1 through an annular slit 3. When air is ejected from the annular slit 3, high pressure air flows along the surface of the slit by 'Coanda effect' and jet air is finely divided to form fine air bubbles which are, in turn, ejected into the sludge substance present on the bottom of the water or in water. At this time, fine air bubbles are bonded to the sludge substance separated from the bottom part by jet streams or the sludge substance suspended in water to float the sludge substance.  Continuously, air bubbles having a relatively large diameter generated from an air bubble generator 8 are bonded to the sludge substance having fine air bubbles bonded thereto to increase buoyancy to increase the rising speed of the sludge substance.

Title: Production of diffraction grating
Inventor: KUWAMURA YUJI
IPC: H01S5/00
Filed: 1986-01-14
Abstract: PURPOSE:To easily manufacture a diffraction grating of a lambda/4 shift type having the same shape and quality within a substrate surface by irradiating and exposing the interference pattern obtd. by superposing two beams having phase differences from each other on one kind of photoresist. CONSTITUTION:An optical path difference in the stage of reflection arises between recesses and projections when an incident wave 9 is made incident perpendicularly on a reflection mirror 5 and therefore, the phase difference arises in the reflected wave 10 reflected at both parts. The phase difference delta is in the relation delta=4pid/lambdaL if the thickness of the ruggedness of the reflecting mirror 5 is designated as (d). The reflected wave 10 reflected on the reflection mirror 5 advances through a half mirror 4 to the substrate 7. On the other hand, laser light 8B advancing to the optical system on the right side in figure (a) advances to the substrate 7 by passing approximately the same optical system as the optical system on the left side. The interference pattern partly reversed in the ruggedness is obtd. when the reflected wave 10 subjected to phase matching and a plane wave 11 are superposed at an optional incident angle theta on the substrate 7. The easy manufacture of the lambda/4 shift type diffraction grating is made possible by such interference pattern.

Title: Untwining device for punch winding of package
Inventor: OTOSHIMA HIRAO
IPC: B65H67/08
Filed: 1987-01-13
Abstract: PURPOSE:To draw out that yarn end in a slit which has bitten in fast, without causing damage to the bobbin by pulling part of a punch wound yarn in the axial direction of bobbin, and pulling the yarn portion between a gripping member and slit with bending by the maximum edge part of a guide member having a greater dimension than the outside dia. of bobbin. CONSTITUTION:Part of a punch wound yarn of a package P2 is gripped by a yarn gripping member and pulled in the axial direction of bobbin B2, and the yarn Y3 between the griping member and slit 140 is pulled with bending by the maximum edge part of a guide member 187 having a greater dia. then the outside dia. of the bobbin B2. Therefore, a tensile force acting in the radial direction of bobbin B2 is applied to the yarn between the slit 140 and guide member 187, and the drawout force from slit 140 will become greater than solely pulling in the axial direction of bobbin B2. Thus that yarn end in the slit 140 which has bitten in fast can be drawn out without causing damage to the bobbin 140.

Filed: 1981-01-22
Abstract: PURPOSE:To eliminate dust on wafers and noise caused from irregularity of wafer surfaces for detection of accurate location of alighment marks by using correlation between data on a known location of alignment mark and data on deflection position detected by electron beam scanning. CONSTITUTION:Beam deflecting data provided by a deflection signal generator 16 is converted to analog signals by a DA converter 15. These analog signals are applied to a deflecting coil 2 around an electron beam 1 through a deflection amplifier 14 to sweep on a wafer 3 including an alignment mark 4 by a distance of a preset span. Next, reflected electrons from the mark 4 and wafer 3 are caught by a detector 5 provided around the electron beam 1 and are amplified by an amplifier 10 to obtain a mark detecting signal, which is digitized through an AD converter 11 to compare it with a threshold value 13 preset for detecting edge of the mark by a comparator 12. By this procedure, if the detecting signal matches up with the threshold value 13, data from the generator 16 is stored in an edge location memory 17 which is under ready for read-in status and is sent to a correlation processing circuit 18 to find correlation of each beam scanning for the purpose of selection of location data.

Abstract: PROBLEM TO BE SOLVED: To easily provide a light shielding means at a proper position by integrally forming the light shielding means which is formed by providing a fine ruggedness on the surface of an external effective diameter part, at the external effective diameter part. SOLUTION: On the surface of an external effective diameter part 2, a fine ruggedness 3 is provided. This fine ruggedness 3 is a light shielding means 4 for preventing the transmission of optical signals to the emission side of an optical lens.
