Title: Optical recording medium and focus controller thereof
Inventor: WASHIMI SATOSHI
IPC: G11B7/24041
Filed: 1989-07-18
Abstract: PURPOSE:To allow the easy focusing of respective light rays to corresponding recording layers by arranging the recording layers of the optical recording medium having plural kinds of the recording layers which are different in the absorption wavelengths of the light rays in such a manner that the absorption wavelengths increase sequentially from the light incident side. CONSTITUTION:The recording layers consisting of n layers are provided on a transparent substrate 1 and the respective recording layers K1 to Kn are constituted of different kinds of photochromic materials. The absorption wavelengths lambda1, lambda2 to lambdan of the respective recording layers K1 to Kn increase and are lambda1 <lambda2< to <lambdan as the recording layers part from the substrate 1. The thicknesses of the respective recording layers K1 to Kn are so set that the distances between the recording layers K1 to Kn-1 and the recording layer Kn coincide with the chromatic aberrations of the wavelength lambdan of the wavelengths lambda1 to lambdan with the light of the wavelength lambdan. The light rays of the lambda1 to lambdan can be thereby converged respectively onto the recording layers K1 to Knin the state of the focusing lens existing in the position where the the light of the wavelength lambdan is converged onto the recording layer Kn. The light rays corresponding to the absorption wavelength lambda1 to LAMBDAn in the recording layers K1 to Kn are converged as the light rays for recording and reproducing to the respective layers in such a manner.

Title: Analyzer with liquid level sensor
Inventor: ISHIZAWA MASAHITO
IPC: G01N35/10
Filed: 1993-07-28
Abstract: PURPOSE:To ensure detection of liquid level by coating the outer periphery of a dispenser probe, except one end thereof, and the inner/outer peripheries of a metal pipe with insulation coating and sustaining a stabilized insulation resistance between the dispenser probe and an outer peripheral conductor thereby eliminating the influence of disturbing elements. CONSTITUTION:A dispenser probe 8 is coated on the outer periphery, except the forward end thereof, with a dielectric coating material 6 in order to increase the surface resistance and connected with a liquid level detecting substrate. The probe 8 is further covered with an insulating material 7 which is covered with a metal pipe 5 having coated inner and outer peripheries. The metal pipe 5 is grounded and the probe 8 is shielded except the forward end thereof so that it is not susceptible to disturbance noise. Since the outer periphery of the probe 8 and the inner/outer peripheries of the metal pipe 5 are applied with coating 6, insulation resistance between the probe 8 and the metal pipe 5 does not decrease even if the surface resistance of the insulation material 7 decreases due to adhesion of liquid to the entire probe resulting in the stabilized shielding effect.

Title: Color printer
Inventor: FOLKINS JEFFREY J
IPC: B41J2/525
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce a 'black in yellow' pollution or a mutual pollution due to the combination of other colors by making a lamp irradiate a photoreceptor and removing the charge of the photoreceiving body before the next re- electrification of the photoreceiving body, which is performed to expose a next color image, after developing a 1st toner layer. SOLUTION: In a 2nd cycle, re-electrification only by a DC is performed well by exposing a photoreceptor so that the charge of a non-exposed area in an image area is made to lower before the re-electrification. Then, in a n electrophotogrophic device, a pre-electrification erasing lamp 18 is used to expose the image area. Therefore, the lamp 18 is lit when the image area advances passing through the lamp 18. After passing through the lamp 18, a DC scorotron 20 re-electrifies the image area to a charge level which is desirable to expose and develop a yellow image. In this case, an AC scorotron 22 is not used. The re-electrified image area advances to an exposure station 24.

Title: High speed alignment exposure
Inventor: ARII KATSUYUKI
IPC: G03F9/00
Filed: 1985-08-23
Abstract: PURPOSE:To shorten the time required for alignment by a method wherein position data are collected while a wafer is shifting in one exposure field to input any corrected data in a controller as soon as a deflection from a theoretical value is detected. CONSTITUTION:An alignment patter 9 is formed of a linear part several mum wide and projections 10 provided intersecting with the linear part while the interval forming the projections 10 are made wider in the part near the shift- starting point and narrower in the part approaching the stop point 11. Therefore, when a wafer starts shifting, alignment marks on reticle and alignment patterns on the wafer are dually detected to collect the position data on shifting amount by the projections 10 as well as on the deflection from an X axis line in Y direction. Through these procedures, the interval of projections 10 is made narrower in the part approaching the stop point 11 to decelerate the shifting speed in X axis direction preventing the wafer from vibrating after overrunning the stop point 11 while enabling the wafer to stop softly at the stop point 11.
