Title: Multiplication device
Inventor: ISHIKURA SATOSHI
IPC: G06F7/52
Filed: 1994-08-03
Abstract: PURPOSE:To provide a parallel operation type multiplication device which can reduce its occupying area and power consumption without increasing the operating time. CONSTITUTION:When a multiplier is inputted to the DB cells BD1-BD6 consisting of the multiplier input parts and the Booth decoder parts respectively, the multiplication/addition circuits MA1-MA6 generate the partial products and perform the serial multiplications. Then the current driving capability is increased for the partial product generation circuits of the upper circuits E1 and MA2. Meanwhile the current driving capability is set at a medium level for the partial product generation circuits of the middle circuits MA3 and MA4, and the current driving capability is reduced for the partial product generation circuits of the lower circuits MA5 and MA6. That is, the operating time is delayed more toward the later processes and therefore no difference is produced as a whole among the operating times. Thus the current driving capability is reduced less for the partial product generation circuits which are used in later processes. As a result, the occupying area and the power consumption can be reduced for a multiplication device.

Title: Liquid coating apparatus and control thereof
Inventor: ISHIZUKA KATSUSHIGE
IPC: B05D1/26
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To shorten the total length of a tube functioning as a passage of a coating liquid and enhance response of liquid ejection by integrating a liquid ejection means comprising a coating liquid container, a pushing pressure roller, a guide and a tube into a single unit and disposing the unit in a vicinity of a coating object matter. SOLUTION: When a coating object matter is positioned automatically, a robot controller 30 transmits a normal rotation drive signal for a rotation unit 5 in an ejection unit 10 to a tubing dispense controller 20 and moves the entire ejection unit 10 to a brow 41 front end of an air blow unit 40 at the time when a specified time has elapsed, and then transmits a blow command signal to the dispense controller 20. The ejection amount of a coating liquid in a coating liquid container 1 is adjusted according to the rotational speed and rotation time of a pushing pressure roller 4 of the rotation unit 5. In this case, because the ejection unit 10 is separated from the dispense controller 20, the total length of a tube 2 functioning a passage of the coating liquid can be shortened.

IPC: B41J2/52
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To enable a device to stably perform an excellent gradation expression by properly correcting variations in a gradation characteristic when an inflection point is generated in the change of an output image density caused by the variations in a dot area ratio. SOLUTION: An input image in which a dot area ratio is changed is developed to obtain the change of an output image density and to detect whether or not an inflection point exists in the change of the output image density by a first detecting means. When the inflection point is detected in the change of the output image density, a developing condition is adjusted so as to eliminate the inflection point by the first correcting means. Then, an input image changing resolution at the same dot area ratio is developed to obtain a density difference in the output image density and to detect whether or not the density difference in the output image density is greater than a prescribed value by a second detecting means.  When detecting that the density difference in the output image density is greater than the prescribed value, the developing condition is adjusted so as to decrease the density difference in the output image density by the second correcting means and the operation is repeated until the density difference is smaller than the prescribed value.

IPC: C21D9/56
Filed: 1980-12-23
Abstract: PURPOSE:To control the roll temperature distribution in the width direction of a roll and to improve the quality of rolling materials, by installing heat pipes in the axially hollow part of a roll to make a heat exchange between the roll and said pipes possible, at the rolling of materials to be rolled by the roll. CONSTITUTION:Heat pipes 4, 4' are installed in an axially hollow part 3 of a milling roll 1 to bring their contacting parts 4-1, 4'-1 into contact with the central part 1-1 of the roll 1 and other contacting parts 4-2, 4'-2 with both end parts 1-2 of the same, respectively. When a material 2 to be rolled is rolled by the roll 1, heat is transferred to both ends 1-2 from the central part of the roll 1 through the heat pipes because the temp. of the central part 1-1 is higher than that of both the ends 1-2, and then the temp. distribution in the direction of the roll 1 width is made uniform. Accordingly, irregular shapes of a rolling material 2 caused by the temp. difference in the temp. distribution in said direction are prevented. One end of the heat pipe is placed at the outside of the roll to make said pipe heat-exchangeable. It is equally well to be made movable in the inside of the hollow shaft.

IPC: G11B7/085
Filed: 1988-07-22
Abstract: PURPOSE:To attain enough exact track seek even with the compact seek motor of low power by detecting the position of a light velocity fine moving member to an optical head and moving the optical head according to detected information. CONSTITUTION:In the beginning condition of the seek, a detecting signal from a speed detector 11 is 0 and a speed control means moves an objective lens 2 with defining the reference speed information of a small value as a target speed. Thus, a track pulse is generated and an up down counter 12 executes the down count of the track pulse. On the other hand, the motion of an optical head 20 goes to be motion in a seek direction. A counted value by the down count of the counter 12 is impressed to a ROM13 and reference value information are generated. On the other hand, the counted value is inputted to a comparator 18. When the counted value goes to be a preset value, the comparator 18 generates a signal and the counter 12 is switched to an amplifier mode. Accordingly, the absolute value of the counted value is gradually decreased and the target speed is gradually decreased. Thus, the motion of the head 20 by a seek motor 6 is also decelerated.

By this method, uniform cooling is possible without causing deposition of water drops on the material by the blowing of atomized water, nor causing partial supercooling. Moreover, no trace of damage nor deformation is generated since the material is treated by hanging. A knob is attached to the center of the tempered material, and a metallic ring is fitted to the periphery. Thus, a finished product is obtd.
