Title: Thermal gradation recorder
Inventor: NAMOTO YOSHITERU
IPC: H04N1/23
Filed: 1985-01-14
Abstract: PURPOSE:To reduce the deterioration of printing quality by constituting the titled device with contiguous thermal resistance elements displaced in a subscanning direction. CONSTITUTION:A thermal head 2 is connected to a common electrode 2b and an individual electrode 2c by providing a thermal resistance element 2a with a displaced value l in a subscanning direction. The displaced value l is set within the range of 1/10-1/4 of a reciprocal of a thermal resistance element arrangement density so that a printing dot interval in a subscanning direction and a density dispersion in said direction may become less conspicuous. If the thermal resistance element 2a is thermally driven at a long voltage application time, large printing dots of high color development rate and high concentration are obtained. If the voltage application time is short, the printing dots become small and at the same time, the color development rate becomes low, thus recording at low concentration. When the recording is made at low concentration, the printing dots are dispersed in a subscan direction, so they are less conspicuous. Even when the recording is made at high concentration, the dot interval is dispersed in a subscan direction to reduce deterioration of printing quality.

Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent positional shift of a cover provided with a thermal head being fixed rotatably to a body case encasing a platen and coming into pressure contact with the platen at a position of closing the body case. SOLUTION: A fitting structure 13 comprising a protrusion 9 and a recess 11 is disposed between a cover 4 and a body case 2. The protrusion 9 and the recess 11 have guide faces 10, 12 substantially parallel in the tangential direction at a position on the rotational track of the cover 4 where the body case is closed. When the body case 2 is closed by the cover 4, the guide faces 10, 12 are slid to guide the cover 4 to a specified position of the body case 2. When movement of the cover 4 is regulated in the rotational direction because the body case 2 is closed, movement in the direction substantially orthogonal thereto is also regulated through fitting of the fitting structure 13. Consequently, relative positioning can be made accurately between a thermal head 5 and a platen 6 resulting in the enhancement of print accuracy.

Abstract: PURPOSE:To constantly maintain delivery force in spite of variations of temperature, power supply voltage, etc. by feeding back pulsating current, which runs to a electromagnetic coil of an electromagnetic pump, to a control circuit which controls delivery force of the electromagnetic pump after detecting the pulsating current. CONSTITUTION:When a pulsating signal (l) is given to the base of a transistor (Q) via a resistor (R2), pulsating current (lp) having the same pulse shape as that of the pulsating signal (b) runs to an electromagnetic coil (M) of an electromagnetic pump and delivery force of the electromagnetic pump is controlled. Pulsating current (Ip) is detected as terminal voltage of a resistor (R3), averaged by an integration circuit which consists of a resistor (R4) and a condenser (C1), amplified by an operating amplifier (A) which is given a negative feed back by a variable resistor (RV2) and then fed back to a control circuit (CT) via a contact point of a resistor (R1) and a variable resistor (RV1) via a resistor (R5). Therefore, since pulse width decreases even if current value of pulsating current (Ip) increases, pulse area of pulsating current (Ip) does not vary and constant delevery force is maintained.

Title: Method for decreasing electromagnetic interference radiated by crt display, and device therefor
Inventor: RINDAL ABRAHAM E
IPC: G09G1/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To effectively decrease electromagnetic interference (EMI) without exerting influence on display performance of a display. SOLUTION: The clock signal is phase-modulated periodically to disperse spectral energy of clock higher harmonics. A frequency of a signal A of a main oscillator is made N times as high as that of picture element clock signal, and is dropped by a clock dropper at every M times (every horizontal synchronous pulse) to be changed in the phase (B), and then it is divided by N to be made as clock signal C. Although the picture is skewed because of a time shift of video data signal D, this can be eliminated by time-shifting the horizontal synchronous signal E in phase with the video data signal D. It is possible to disperse the spectral energy outside of the bandwidth of a standard EMI measurement window by taking a sufficient rate of phase change.
