Title: Method and apparatus for controlling ink-jet color printing heads
Inventor: LOGAN DAVID J
IPC: H04N1/405
Filed: 1993-07-08
Abstract: Method and apparatus are provided for controlling a group of ink-jet printing heads to selectively apply (or not apply) dots of one color and of substantially fixed size in random dot pattern arrangements to dot positions of a plurality of pixel areas located sequentially along a line scanned by the printing heads. A sequential series of F integral value color image density signals representative of the tone value at which a respective one of the pixel areas is to be printed by the colored dots is produced. A number of different dot pattern arrangements are listed in a table for the F integral values to produce the tone value representative of a density signal of such an integral value. One of the dot pattern arrangements is randomly selected whenever a color density signal of the integral value appears. The group of ink-jet heads apply colored dots onto the dot positions of the associated pixel area in accordance with the pattern randomly selected.
Patent HK-72797-A (HK)
Title: Process and device for decoding image signals containing additional information
Inventor: PLANTHOLT MARTIN
IPC: H04N9/79
Filed: 1997-05-29
Abstract: The letterbox process is considered in order to introduce a 16:9 large screen format compatible with existing television standards. The 4:3 receivers represent the 16:9 image information in a compatible manner with black stripes at the top and bottom edges of the image. In order to fill out the screen of a 16:9 receiver, additional information that allows an image with an improved quality to be obtained is transmitted in the black stripes of the compatible 4:3 transmission. In order to record PALplus signals on SVHS recorders, the additional information may be partially decoded. For that purpose, the additional information is demodulated before being recorded and is then recorded as basis band signals. Before being reproduced by a 16:9 receiver, the recorded additional information may go backwards through the decoding process carried out before recording, i.e. may be coded into an image signal containing additional information. In 16:9 television receivers, the additional information is then decoded again. Besides the disadvantage that represents the signal recoding effort in the recorder, the cascade coding/decoding worsens the signal-to-noise ratio in the signal. According to the invention, image signals containing partially decoded additional information recorded on SVHS recorders are directly supplied for further decoding to the 16:9 receiver and are not subjected to the corresponding partial decoding in the 16:9 receiver.

Title: Pulse drive circuit of transformer coupling type
Inventor: SHIDA KOUJI
IPC: H03K17/66
Filed: 1979-01-08
Abstract: PURPOSE:To prevent the adverse effect to load due to the sag of transformer, by providing the resistor in parallel with the primary coil of the transformer. CONSTITUTION:The resistor R0 is connected in paralle with the primary coil of the pulse drive circuit coupled with transformer. If the switching transistor Q2 is turned on with the rectangular wave (a), the current (c) flowing the path between the resistor R0 and the primary coil of the transformer T, flows so that the effect of the primary current (b) can be cancelled and flows so that the increase in the exciting current (b) can be cancelled. As a result, the effective primary current (d) can suitably be suppressed with the effect of the resistor R0 and unnecessary exciting current due to the effect of sag can be removed. That is, the sag produced as the storage of exciting current is removed in the transformer and the exciting current can rapidly be turned off when the excitation is OFF.

Title: Lift cord stopper for roman shade or the like
Inventor: WARATANI KIMIO
IPC: E06B9/324
Filed: 1991-01-08
Abstract: PURPOSE:To facilitate an operation of threading a lift cord to lower smoothly a screen by suspending the lift cord through a guide roll in a head rail into a case to extend through a main body between a pair of pinch rollers and exit outward from the bottom of the case. CONSTITUTION:When a lift cord 21 is suspended vertically from a head rail 10, it automatically enters a case 20, passes between pinch rolls 23, 23' of a main body 22 and exits the case 20 from below. Since the lift cord 12 does not receive resistance other than the rotational resistance of the pinch rollers 23, 23' in a stopper, the elastic force of a spring 28 pressing the pinch rollers 23, 23' against each other allows even a light screen to be lowered surely by its own weight so long as the rotational resistance of the pinch rolls is set larger than the slide resistance of the main body 22 and case 20 and smaller than the frictional resistance between the lift cord and pinch rolls. Also, the screen 13 is lowered by its own weight irrespective of its position when a knob 29 is operated to open the pinch rolls 23, 23' against the spring 28.

Title: Frequency converter and its controlling method
Inventor: OKUYAMA TOSHIAKI
IPC: H02P3/18
Filed: 1979-01-10
Abstract: PURPOSE: To enhance the power factor of a power supply by regenerative control employing a voltage-type pulse-width modulation converting means as a converter on the power-supply side with converts AC voltages to DC and as an inverter on the motor side which supplies variable-voltage variable-frequency voltage to a motor.  
     CONSTITUTION: A DC input current of an inverter 2 flows from a converter 5 to an inverter 2 in the case of a reverse-conversion operation, and from the inverter 2 to the converter 5 in the case of forward-conversion operation. In both cases, the voltage of a capacitor 15 is controlled at a constant value, and the DC output current from the converter 5 is always balanced with the DC input current of the inverter 2. That is, the operation of the inverter 2 and that of the converter 5 are opposite each other. Since both the converter and the inverter are sonstituted by a PWM converting means, the motor current forms a sinusoidal wave, torque ripples are not generated, and the harmonic waves of the power supply are not generated either.
