IPC: G06T5/00
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide the half toning technology where a color shown by a generated color image is kept constant at all times substantially even when a dot forming position is more or less fluctuated in a subscanning direction. SOLUTION: In the half toning where a pixel value of C, M, Y planes of a multi- gradation color image is received and converted into C, M, Y dot information, a C, M, Y dot growing pattern is set so that skin, gray and blue colors that are important colors with respect to a visual sense of people have always a prescribed coloring. That is, M, Y dot lumps 32, 33 that are major components of a skin color in a low density area are grown at entirely and not overlapped positions in the main scanning direction. Even when dot forming positions are more or less deviated in the subscanning direction, since the M, Y clot lumps 32, 33 are not overlapped, the coloring of the skin color is constant.  In the medium density area, C, M dot lumps 34, 35 strongly affecting gray and blue colors are placed so that one color dot lump is placed to be overlapped over two dot lumps placed at different positions of other colors in the subscanning direction. Even when the dot forming positions are more or less deviated in the subscanning direction, since the overlapped amount of the C, M dot lumps 34, 35 is constant, the coloring of gray and blue colors is constant.

Filed: 1980-10-07
Abstract: PURPOSE:To obtain a wide PLL frequency range with detuning reduced, by controlling a voltage-controlled oscillator VCO by a voltage regarding an output frequency setting digital data supplied to a programmable frequency divider. CONSTITUTION:A digital frequency-division indication signal P supplied to a programmable frequency divider 12 is supplied to a D/A converter 22 as well. The output Vo of the converter 22 has a voltage value corresponding to the specified frequency-division ratio N of the frequency divider 12, and a VCO10 is controlled by the voltage. The VCO10 has an oscillation frequency specified by the Vo, and the frequency is divided by N at the frequency divider 12, whose output is compared, in terms of phase, with a reference signal from a reference frequency generator 14 by a phase comparator 16 to supply their difference to the VCO10 as a voltage  Vp through an LPF18. The principal decision on a PLL output frequency by the  signal P is made by the output Vo of the converter 22 and only the correction for accurate PLL output setting is performed by the output Vp of the LPF18, so the modulation sensitivity of VCO is set small, thereby reducing noises in the PLL output signal following up large modulation sensitivity.

IPC: B61L25/06
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To track a train normally by referring to a track circuit state storage part to confirm the state of a preceding track circuit adjacent to a track circuit in the proceeding direction of a train at the time of input of a signal indicating the change of a track circuit state from falling to lifting, and determining lifting of the track circuit in case the preceding track circuit falls within the specified time. SOLUTION: When a track circuit previously specified that a relay is unliable to fall is judged to be lifted (700), a lifting monitor time element sets the specified time, and whether the specified time has elapsed is judged (701). When the specified track circuit falls again during the subtraction of the lifting monitor time element and the fall is confirmed by a track circuit state detecting part, the state of track circuits longitudinally adjacent in a proceeding direction is judged referring to a track circuit state storage part (702). When the fall of both side track circuits is judged, lifting is determined, the lifting monitor time element is reset, and a proceeding direction and an identification number allocated to the specified track circuit are effaced (706).

Title: Heater controller
Inventor: ADACHI KAZUHIDE
IPC: G05F1/10
Filed: 1990-05-29
Abstract: PURPOSE:To prevent an overcurrent from flowing in a heater when the setting temperature of the heater is altered to a high temperature by detecting that the overcurernt flows in the heater by means of the deviation signal of a temperature controller and setting the maximum output of a power controller to be smaller than a setting output value for prescribed time. CONSTITUTION:For controlling the temperature of the heater 2, a slope setting unit 9 sets the maximum output and the temperature slope of the power controller 8. A target temperature is set by operating the temperature controller 4. When the target temperature of the heater 2 is altered to high, a relay contact point 5 in the internal part of the temperature controller 4 is turned off and the deviation signal (b) is turned off since a detection temperature by a thermocouple 3 is beyond the range of a proportional band. At that time, the temperature controller 4 gives an instruction to supply power to the heater 2 by the maximum out put to the power controller 8, When a contact point signal (a) detects that the contact point 5 is turned off, a sequencer 6 detects an overcurrent and turns off the excitation of a relay coil 7 for a prescribed period (t). Thus, a relay contact point 12 is turned off, a resistance 10 is inserted and the output of the controller 8 becomes small. Consequently, the overcurrent flowing by overshooting and the like at the time of altering the setting temperature can be prevented.
