Patent JP-S60174677-A (JP)
Title: Printing system for line printer
Inventor: MOCHIZUKI YASUO
IPC: B41J19/76
Filed: 1984-02-21
Abstract: PURPOSE:To enable the relative movement of a head and a paper to be securely stopped before a printing-starting position in the next line is reached, by a method wherein a means is provided for detecting the printing of a dot at a predetermined position during printing dots in a line, and a DC motor is stopped during printing in the line in response to an output from the detecting means. CONSTITUTION:A controlling circuit 1 rotates the motor 2 forward when the completion of reception of data for one dot line is detected through a reception completion signal 30. When the paper is fed to a predetermined printing-starting position (x), data stored in a printing buffer 5 are fed to the printing head by one group at a time, thereby printing. When a predetermined printing position, e.g., printing of the 6th group, is detected during printing dots in a line, the circuit 1 stops the operation of the motor 2. Even after this stoppage, the paper is fed by inertia, and printing of the 6th and later groups is conducted during the inertial paper feeding. The feeding of the paper is stopped whe the head 7 reaches, for example, a position (y). Accordingly, since the driving of the motor 2 is stopped by taking the inertial rotation into consideration, the position of the head 7 relative to the paper is prevented from coming beyond a prescribed printing-starting position in the next line.

Title: Time display device
Inventor: NAGATA YOSHINOSUKE
IPC: G01D7/00
Filed: 1978-03-14
Abstract: PURPOSE:To perform easy-to-see displaying free from variations in contrast by putting the whole of display segment electrodes once in an erased state immediately before shifting to the next time display. CONSTITUTION:At the fall of the minute signal T outputted by a frequency divider 2, a color erasing pulse signal E is generated from a color erasiny signal generating  circuit 3 and all the segments of the minute digit displaying ECDI of an electrochromic display (ECD) 9 are erased through a minute digit driving circuit 4. At the  fall of this color erasing pulse signal, a coloring signal generating circuit 8 generates  the coloring pulse signal to put the circit 4 in the coloring state. Hence, the minute  digit numbers of good contrast are displayed in the BCDI by the minute pulse signal  immediately thereafter. The same holds true of the 10-minute digits, hour-digits and 10-hour digits, thus the good and easy-to-see displaying free from any residual  color is accomplished because the coloring takes place after color erasing.

IPC: G01N21/25
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To provide accurate concentrations of components contained in a solution by analyzing the concentrations using air or gas having the same components of bubbles as a reference material. SOLUTION: A cell 1 having gas sealed is provided in an optical path between a spectral means 3 and a detector 4, a monochromatic light from a light source 2 is separated into its spectral components by this means 3 and scanned by the light of wavelength λ, and the cell transmitted light then is received by the detector 4 so that the reference spectrum I is obtained. A solution (S) is poured into the cell 1 and a sample spectrum I is obtained in the same way. Secondly, an absorbance spectrum (A) is found using the both spectra and its data are processed so as to provide concentrations responding to the solvent and the components respectively. When bubbles are contained in the solution (S), a sample spectrum (I) becomes a smaller value than a case without containing the bubbles so that the total concentration (T) becomes less than 100%.  Therefore, when (T) is some value or more, it is judged that the bubbles are not contained and, when it is less than that, it is judged that they are contained.

Filed: 1989-02-08
Abstract: PURPOSE:To prevent overshoot from occurring by making a set temperature which is the reference of the control of temperature different between when a copying button is depressed and when it is not depressed. CONSTITUTION:When the surface temperature of a heating roller 2 attains T3, a CPU 9 has a copying action started and switches the reference temperature of the control of temperature to the 1st set temperature T1. After the lapse of t1 since the start of the copying action, a transfer paper P reaches the heating roller 2, when the surface temperature of the heating roller 2 is the 1st set temperature T1 and ordinary fixation is performed. Thereafter, the control of temperature is performed at the 1st set temperature T1 as a reference. Thus, the fixation and the conveyance of the transfer paper P is performed while absorbing the heat, thereby preventing the overshoot from occurring.

Title: Printer employing ink ribbon
Inventor: SHIMIZU YOSHITAKA
IPC: B41J33/30
Filed: 1990-02-09
Abstract: PURPOSE:To prevent data from being printed on the spliced part of ink ribbons and thereby improve printed image quality by monitoring the splice in accordance with the winding amount of an ink ribbon. CONSTITUTION:A switch 4 is installed at a position where an arm 5 fixed to a ribbon winding roller 3 depresses the switch 4 once, when the ribbon winding roller 3 makes a single round of rotation. For this reason, the arm 5 depresses the switch 4 by the number of rotations of the ribbon winding roller 3, each time an ink ribbon 1 has been taken up. Then if the winding amount of the ink ribbon 1 (the number of times of switch 4 depressions) is monitored for the ink ribbon 1 whose splice position is determined in advance, the position for the splice part of the ink ribbon 1 is confirmed. Thus it is possible to prevent data from being printed at the spliced part of the ink ribbon and thereby improve printed image quality.
