Abstract: PURPOSE:To continuously and quickly control the size of a light beam in a similar form by providing a continuously changing groove on the peripheral surface of a disk or a polygonal prism body and irradiating this groove with the light beam to change the size of the light beam. CONSTITUTION:A groove 2 whose width and depth are continuously changed is provided on the peripheral surface of a disk 1, and the disk 1 is rotated around a revolving shaft 3 to change a light beam 4 to an arbitrary size in a control position 5. For example, when the disk 1 is rotated clockwise, the size is successively changed to A to D in accordance with the form of the groove 2. In this case, the point D is the practical control reference point of the form formed by the groove 2, and the form of the groove 2 is expanded downward in a similar form with the control reference point as the center, and the center of the form is moved downward. If it is necessary to linearly arrange the center of the form, namely, the center of dots, the pulse intervals of the light beam or the angle or irradiation of the light beam is changed to correct the deviation of the center of the form.

Filed: 1988-12-05
Abstract: PURPOSE:To eliminate the operation of an acceleration pedal more than the requirement by using the change of the intake air negative pressure accompanied with the operation of a clutch pedal and a manual transmission at the time of starting a car to form a throttle valve so as to be opened from the idle position through a negative pressure mechanism. CONSTITUTION:When a car is started, a clutch pedal is operated, and a manual transmission is changed from the neutral to the first stage of the forward, and next, the clutch pedal is cancelled without operating an acceleration pedal, then, the engine speed lowers a little to lower the intake air negative pressure, on the other hand, the negative pressure in a back chamber 12 becomes high. Since a diaphragm 10 pulls an arm 6 through a connected lever 8, a throttle valve 3 is opened to rise the engine speed. When the edge of the throttle valve 3 passes through an opening 17a, since the negative pressure near the atmospheric pressure is led into a negative pressure chamber 11, the diaphragm 10 is further sucked to the back chamber 12 side to open the throttle valve 3. Thereafter, the negative pressure in the back chamber 12 lowers with the passing of the time through a communicating passage 13 in which a throttle 14 is provided, and the throttle valve 3 is gradually closed.

Title: Decoder driver circuit
Inventor: FURANKU ARUFURETSUDO MONTEGARI
IPC: H03K19/0944
Filed: 1991-10-29
Abstract: PURPOSE: To realize high performance and high density by using FET as a pull up device and driving output lines with a PNP transistor at the time of executing decoding. CONSTITUTION: The output lines 410 and 412 from a decoder 404 become high voltage level in a non-enable state and become low levels in an enable state. The input lines 414A-416N of decoders 426A-426N are connected to the output lines 410 and 412 of the decoder 404. When one of the input lines 414A-416N is not enable, the decoders 426A-426N maintain the word lines 428A-428N to a non-enable state. Since a driving circuit operates as an invertor, the word lines 428A-428N are made enable when the voltage levels of the lines are low and are maintained to be non-enable when they are high. Then, a field effect transistor is used as the pull up device since the output lines are separated and are driven. Furthermore, high performance and high density can be realized since the PNP transistor drives the output lines.

SOLUTION: A CPU 81 executes a color correction processing for converting picture data formed of the gradation values of R, G and B into data of the gradation values of C, M, Y and K used in a color printer 22. The CPU 81 executes a multivalue processing for converting the gradation value of original picture data into the gradation values that the color printer 22 can express for respective picture elements for picture data CD which is thus color-corrected. Data is made into the multilevel of the three gradations of 'absence of the formation of dots', 'formation of small dots' and 'formation of large dots'. In the 'formation of large dots', the presence or absence of formation is judged by the two types of methods of a dither method and an error diffusion method.
