Title: Wiring pattern of strain sensor
Inventor: OTAKI KIYOKAZU
IPC: G01L9/04
Filed: 1992-11-20
Abstract: PURPOSE:To obtain the wiring pattern of a strain sensor for relaxing the process control for a strain gauge formation position. CONSTITUTION:Strain gauges 14 and 16 for detecting compression distortion and gauges 18 and 20 for detecting pull distortion are laid out at radius positions (a) and (b) where the absolute values of compression distortion and pull distortion are equal and both change rates are equal. Therefore, when the positions for forming the strain gauges 14 and 18 or 16 and 20 deviate, the fluctuations of the compression distortion and pull distortion caused by the deviation are nearly equal if the deviation is equal to or less than a certain level, thus preventing the balance of wheatstone bridge circuit which is constituted by the gauges from being affected greatly.

Title: Digital data recording paper
Inventor: YOSHIDA HIROICHI
IPC: G06K19/00
Filed: 1990-11-17
Abstract: PURPOSE:To prevent data read error by forming read mark areas at two points in linearly symmetrical position relation, storing an H signal mark in one of the above read mark areas and storing an L signal mark in the other one. CONSTITUTION:Read mark areas DL and DH are formed at two points in the linearly symmetrical position relation to a diagonal P, the H signal mark is stored in one read mark area DH and the L signal mark is stored in the other read mark area DL. Therefore, when reading data, the direction of feeding recording paper to a sensor can be detected by detecting an X axis baseline 1, Y axis baseline 2 and additive mark 3 by the sensor and discriminating the relative position relation between the sensor and the recording paper by the arithmetic processing of a microcomputer. Further, even when the binary mark of the recording paper is detected from the back as well, it is excluded as error since the mark area DH<DL is inversed to the diagonal P. Thus, read error caused by turning the recording paper inside out or missing the read direction can be prevented without fail.

Title: Liquid developer
Inventor: NAGASE KOICHI
IPC: G03G9/13
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a black liquid developer showing excellent re-dispersion property by specifying the density of a carbon black used as a coloring agent and controlling the specific surface area by BET method to a specified value or lower. SOLUTION: The liquid toner is prepared by dispersing 0.1 to 20wt.% color particles essentially comprising a pigment and a resin in a petroleum-based hydrocarbon carrier liquid. The color particles have 0.3 to 5μm average particle size. The color particles essentially consist of a carbon black and a resin, and the amt. of the carbon black in the particles is between >=5wt.% and <=30wt.%. The carbon black has pH>=7 and <=50m<2> /g BET specific surface area. If the specific surface area exceeds 50m<2> /g, the re-dispersing property of the particles deteriorates. If the pH is <7, the dispersibility of the particles for a rosin- modified resin decreases and the surface of the carbon black exposes, which accelerates the aggregating property among the particles.
