Filed: 1994-09-19
Abstract: PURPOSE: To reduce the noise resulting from an input wire and input resistors by forming a matrix with two kinds of drive voltage application means so as to allocate two resistors extended from the input wire to a photoelectric conversion element specifically. CONSTITUTION: A fold-back direction of 1st and 2nd resistors Rd, Re is selected the same as an extended direction of 1st and 2nd input wires D1-y , E1-x at first, then a current induced in a pattern of the resistors Rd, Re by a current flowing mainly to the wire E1-x appears in the 1st resistors Rd, Re toward the wire E1-x in a zigzag pattern. The induced current flows to the wires D1-y , E1-x . Since the resistance of the resistors Rd, Re is set to a prescribed resistance, the more the number of fold-backs in the zigzag pattern is increased, the more resistance of the 1st resistors toward the wire E1-x is decreased and a generated voltage is reduced.  Moreover, currents flowing to the resistors Rd, Re placed opposite to each other are cancelled out in an excellent way by selecting the pattern of the resistors Rd, Re to be in axial symmetry with respect to a center line of the opposed positions.

Title: Production of phase shift reticule
Inventor: MURATA NOBORU
IPC: G03F1/68
Filed: 1993-08-17
Abstract: PURPOSE:To make it possible to form phase shifter films having a uniform film thickness in light transparent parts by controlling the film thickness of the silicon oxide film made to remain as the phase shifter film to a thickness at which the phase of the light transmitted in this part deviates by a half wavelength from the phase of the light transmitted through the other light transparent part. CONSTITUTION:The silicon film 2 formed on a glass substrate 1 is selectively oxidized to form the silicon films 5. The silicon oxide films 5 of the parts not coated with a resist 7 are etched. The film thickness of the silicon oxide films 5 is adjusted to the thickness at which the phase of the light deviates by the half wavelength. The resist 7 is thereafter removed to form the phase shift reticule. The silicon films 2 which are the light shielding films and the silicon oxide films 5 which are the shifter films are intrinsically the same films according to this method and are, therefore, continuously formed, by which the generation of the nonuniformity in the film thickness occurring in differences in level is obviated. The silicon oxide films 5 having the uniform film thickness are formed in the parts of the shifter parts 6 where the light actually transmits.

Inventor: NAGUMO YUZO
IPC: G01N11/14
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To perform a plurality of measurements of characteristics with no restriction on the installing position of probe. SOLUTION: The composite probe for measuring liquid comprises an optical cell 1, a tubular body 11 and a rotary viscometer 10 comprising a rotary drive section 12 and a torque detecting section 13 coupled with the tubular body 11 through a shaft 14 wherein the tubular body 11 is disposed closely to the optical cell 1 on the side of liquid to be measured. Since the tubular body 11 is disposed closely to the optical cell 1, a liquid flow is also produced in the vicinity of optical cell 1 upon rotation of the tubular body 11. Consequently, neutralization and uneven distribution of fine particles, moisture, etc., can be released in the vicinity of optical cell 1 thus suppressing adhesion of sludge thereto. This structure lifts the restriction on the installing position of liquid measuring probe and enhances the accuracy of measurement.
