Abstract: PURPOSE:To select a normal system even when a fault takes place in a line termination circuit by providing a fault monitor circuit so as to generate a control signal for switching any system of transmission lines in duplicate when a fault takes place in a line termination circuit and a line system selection control circuit of the act system. CONSTITUTION:Line termination circuits 3, 4 give a signal (f) used to display a state of a transmission line or a line termination circuit of a 0 system as to whether or not the line or the circuit is faulty and a signal (h) used to display a state of the circuits 3, 4 or a transmission line of 1 system to a fault monitor circuit 6. A selection control circuit 5 gives a signal (g) used to display the state of its own circuit to the circuit 6. The circuit 6 receives the signals f-h to give an input to selector circuits 70, 80 in internal devices 7, 8 and generates a switching signal of selectors 71, 81. When the signal (g) does not indicate any fault, the circuit 6 generates a control signal used to allow the circuits 70, 80 to select a control signal (c) from the circuit 5. When the circuit 5 displays the signal (g), the circuit 6 generates a control signal (j) based on the signals f, h to select a normal system for the circuits 3, 4.

Title: Method for heating cooking rice
Inventor: MIYAKE KAZUYA
IPC: A23L7/10
Filed: 1993-06-28
Abstract: PURPOSE:To set the optimal heating quantity by detecting a highly precise amount of boiling rice. CONSTITUTION:The application of an electric current to a rice-cooking heater 15 is stopped during the immersion and cooking of the rice to dispose a heating- stopping period. A rice-cooking quantity is determined on the drop in the temperature of a container sensor 18 and on the temperature of water at the early time during the period. The change in the temperature of the container sensor 18 is detected, when the application of the electric current applied to the rice- cooking heater 15 is stopped after the control of the heating. On the change in the temperature, the quantity of the heating in the second stage of the stabilization control is corrected by changing the current application degree of the rice-cooking heater 15. The detection of the temperature with the container sensor 18 can precisely be performed without being affected by the heat of the rice-cooking heat 15. Since the detection of the temperature is performed several times, a judgment error caused by the irregular contacts of the container with the container sensor 18 can be corrected.

Then an interval (a) between the blades is adjusted to be about 520 mm, an interval (b) between the blade 18 and the blade 19 is adjusted to be about 75 mm, an interval (d) between the inner and outer blades on a start position is adjusted to be about 453 mm, and an interval (e) between the inner and outer blades on the maximum close position is adjusted to be about 240 mm. Whereby the ties can be effectively tamped even though the intervals of ties are irregular or narrow.

Title: Coloring composition
Inventor: FUNATSU TAKENORI
IPC: C09B63/00
Filed: 1978-12-22
Abstract: PURPOSE: To provide a coloring composition having yellowish color, strong hiding power, excellent resistance and pigment dispersibility without thermal discoloration by containing a red azo lake pigment exhibiting specified crystalline shape as coloring agent.  
     CONSTITUTION: A coloring composition containing a pigment represented by the formula with characteristic peaks near 9.9, 5.5 and 4.4Å of spacings of an X-ray diffraction as a coloring agent. The reason why the above pigment is improved in thermal discoloration phenomenon is probably that, though conventional pigments become amorphous owing to elimination of water of crystallization on heating, this one does not become amorphous in spite of the elimination of water of cristallization and thus exempted from thermal discoloration.

Title: Method and device for forming color image
Inventor: MORIMOTO ETSURO
IPC: G03G15/01
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a color image forming method by which the reproduction of a character with high definition is realized, even for the intermediate density character of a black character and the color image with high image quality overall is realized by discriminating whether each pixel in an image signal is the chromatic or the achromatic color and changing the arrangement of image forming dots, based on the discrimination result. SOLUTION: It is discriminated as to whether the image signal of each color is chromatic data or achromatic color data by the chromatic data/achromatic color data discriminating function of a multi-level processing part 78 before executing an intermediate processing after a processing, such as filtering or color correction. Arrangement of the image forming dots is changed, when the pixels are chromatic or achromatic based on the discriminating result, so that a chromatic case or achromatic are discriminated and the arrangement of the dots is changed-over by a system corresponding to each importance degree. Therefore, resolution for forming the achromatic color image is made higher than that for forming the chromatic one, so that the image with high definition is formed with respect to the black character with a high usage frequency in the achromatic color.

Title: Electronic pen for coordinate input
Inventor: FLECK DAVID C
IPC: G06F3/041
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To vary graphical parameters and control parameters (e.g. the thickness and color of fine) by determining how much control or graphical parameters used for a digitizer coordinate input system vary with a wheel which can be rotated on a center shaft with a finger of an operator through the rotation angle of the wheel. SOLUTION: The rotation of the wheel 7 rotates a gear wheel 15 reversely to the wheel 7 and a potentiometer 17 detects how much the gear wheel 15 is rotated. Thus, the degree or quantity of the rotation of the wheel 7 by the user can be determined. The potentiometer 17 cooperates with other circuits in an electronic pen to detect how much the wheel 7 rotates thereafter toward a tablet (or computer) and outputs an electromagnetic signal showing that. With the quantity or degree of the rotation, the degree of adjustments of control or graphical parameters is determined.
