Title: Medium contrast recording system
Inventor: YAMADA KEIKI
IPC: B41J2/36
Filed: 1988-03-07
Abstract: PURPOSE:To obtain uniform recording density by preventing the generation of the variation in recording density on the same gradation level, by grouping a plurality of gradation level signals to allot a predetermined index showing heat effect at every group and referring to the combination of the indice based on the past and present recording patterns. CONSTITUTION:A gradation level signal 1 is successively inputted to a line memory 2, a judge means 4 and a pulse generating means 8. The first judge means 4 outputs the group number corresponding to the inputted gradation level signal 1 to input the same to a shift register 6 and the gradation level signal 1 before one line from the line memory 2 is inputted to the judge means 5 and set to the corresponding group number to be inputted to a shift register 7. The stage constitutions of the shift registers 6, 7 correspond to the arrangement of heat generating resistors and a pulse generating means 8 receives the gradation level signals 1 and the outputs from the shift registers 6, 7 to read the correction factor preliminarily stored on the basis of a heat effect index to perform the current supply/heat generation of a thermal head 9.

Title: Optical position sensor
Inventor: TOYAMA KIYOSHI
IPC: G01D5/30
Filed: 1988-03-04
Abstract: PURPOSE:To improve the environmental resistance of the optical sensor by connecting an input/output optical waveguide to which a polarizer and analyzer are connected in series to one end surface of a magnetooptical effect element and forming a light reflecting surface on the other end surface. CONSTITUTION:The light signal emitted by a semiconductor laser is inputted to an optical sensor head 15 through an optical fiber 24a. In this case, the plane of polarization of the light signal Aa in the waveguide 21a is in a random state and the signal is converted by the polarizer 26a into a light signal Ba which has a single plane of polarization (linear polarization). This light signal Ba becomes a light signal Ca by passing through a Faraday effect element 27 and is reflected by a reflecting means 28 and passes through the element 27 again to become a light signal Da, which is inputted to the analyzer 30a. Here, the light signal which is inputted to the analyzer 30a has Faraday rotation corresponding to an array of magnetic pieces 29a and only a light signal which has no Faraday rotation passes through the analyzer. Consequently, a digital output corresponding to the array of magnetic pieces 29 is obtained and the absolute position on a scale 13 is detected with a signal generated corresponding to the position on the magnetic scale 13.
