Title: Drawing processing apparatus
Inventor: KATO TOSHIAKI
IPC: B41J21/00
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To enhance the speed for color converting processing of image data and interpreted data in a drawing processing apparatus. SOLUTION: A constitutional color number discriminating part 2A for discriminating whether image data and interpreted data are constituted of a single color in an input analyzing part 1 is arranged between the input analyzing part 2A and an image control part 2. When this image data is judged to be constituted of a single color, a part of color converting processing having been performed with respect to the whole unit region of the image data is omitted and, since the same value as the result of color converting processing is used with respect to the omitted region, a color converting processing speed can be increased.

IPC: G09G3/20
Filed: 1993-03-23
Abstract: PURPOSE:To generate a reference clock with which video data can stably be sampled by a circuit that need not be adjusted by an interface which converts a display signal for the CRT of a personal computer into a signal for a thin display. CONSTITUTION:The personal computer outputs the video data VID, a horizontal synchronizing signal, and a vertical synchronizing signal VS which are generated with its internal clock. This interface inputs the signal HS as a trigger to the PLL circuit composed of means 21-24, and the frequency of the signal HS is divided by N to generate a reference clock VCLKO which has the same period and is in phase with the internal clock of the personal computer. At the rear stage, the clock VCLK0 is counted up to 80 through a counter 25 to detect a back-porch period and then an image valid display period is detected similarly through a counter 29. A horizontal synchronizing signal HS1 for display which indicating only the valid display period and a reference clock VCLK1 for display which makes the reference clock VCLK0 valid only in the period of the signal HS1 are generated.

IPC: G01S13/32
Filed: 1989-03-15
Abstract: PURPOSE:To detect a small target readily even if large targets and small targets are present in close proximity by using an orthogonal sequence as a sequence used for the code modulation of a transmitting signal, and suppressing the generation of the range side lobes of demodulated signals as much as possible. CONSTITUTION:In an orthogonal sequence generator 11, the component of the output signal generated in an M-sequence generator 24 inputs the M sequence of 0.1 into a substituting means (component substituting device 25). In the substituting means, A0e<jphi0> is made to substitute with A0 as a positive real number when the component in the M sequence is 0, and A1e<kphi0> is made to substitute with A1 as a positive real number. A trigonometric function fi(phi1 - phi2) having a phase of phi1 - phi2 becomes the ratio between two functions f2(A1/A0) and f3(A1/A0) of an amplitude ratio A1/A0, wherein the linear expression of a period N in an M sequence as shown in the expression in the figure is a coefficient. The orthogonal sequence is generated in this way. Thus, the generation of the range side lobes of the demodulated signal is suppressed as much as possible, and a small target can be detected readily.

Filed: 1988-03-16
Abstract: PURPOSE:To obtain a prescribed electrification quantity irrespective of humidity by varying the shield potential or the grid potential in accordance with a humidity variation, and controlling a current flowing to an image carrying body from a discharge wire member. CONSTITUTION:For instance, to a shield member 3b, a voltage whose polarity is the same as that of a voltage applied to a discharge wire member 3a is applied through a moisture absorbing member 5 which is converted to a low resistance by a moisture absorption, and also, grounded through a resistance 6 and a varistor 7 for constituting a self-voltage generating element. Accordingly, under high humidity environment, a current for flowing into the resistance 6 from a power source 4 increases and the potential of the shield member 3b rises, a current for flowing to the shield member 3b from the discharge wire member 3a decreases, and a current for flowing to a photosensitive drum 1 increases. In such a way, a potential drop on the photosensitive drum 1 caused by the rise of the impedance of a primary electrifier 3 under high humidity can be corrected, and the surface potential of the photosensitive drum 1 can be kept constant irrespective of humidity.

Abstract: PURPOSE:To obtain an output having high resistance to noise, a wide dynamic range and a large quantity of information, by connecting a light-time converting circuit to the output of a photosensor and converting an optical current into a time to read it after setting an order of light intensity. CONSTITUTION:The signal value of the output of a sensor array (n) for automatic focusing comprising (n) units of photosensors is supplied to a light-time converting circuit L/T to be converted into a pulse of time value. The pulse width period is detected by a pulse width detecting circuit TD for the output of the circuit L/T, and this detecting signal turns on a register M of the next stage. At the same time, the order is set by a counter G while the synchronism is secured at an advance control part AC. The writing is carried out to the register M in order of the intensity of the light which is irradiated to a sensor. Thus the reading is carried out by setting an order of intensity to the output of the photosensor. This can obtain an output which has high resistance to noises, a wide dynamic range and a large quantity of information.

Abstract: PURPOSE:To detect uniformly a change in magnetic flux due to magnetism with high sensitivity by disposing a linear conductive body parallel to a glass plate over the whole surface thereof and providing a magnetic sensor connected to conductive bodies provided on both ends of the glass plate. CONSTITUTION:A plurality of linear conductors 3 are disposed in parallel to be distributed over almost the whole front glass 2 surface of a pinball machine, and conductors 4 having an extremely low resistance value are provided on both ends of the glass plate 2. Both ends of the linear conductor 3 are connected to both ends of the conductor 4 to constitute a magnetic sensor 1.

This current is converted to voltage in a current-voltage converting circuit 7 and amplified by a voltage amplifying circuit 8 to be inputted to a comparing circuit 9. When the output voltage of the voltage amplifying circuit 8 is higher than the upper limit of preset reference voltage or lower than the lower limit, a relay is operated by a relay self- holding circuit 10 to self hold the output voltage. Thus, a change in magnetic flux due to magnetism can be detected surely with uniform sensitivity to drive a warning means.
