Title: Universal pump adjustable of flow rate and pressure having no rotating and sliding parts
Inventor: TANAKA MINORU
IPC: F04B43/00
Filed: 1979-06-30
Abstract: PURPOSE: To eliminate rotating and sliding parts and provide an untroubled pump of long lifetime, by combining an optional number of vibrator plates with one another in a cylindrical form or the like and applying a voltage to the assembly to expand and contract a portion of the cylindrical assembly to change the capacity of the assembly.  
     CONSTITUTION: To cause suction from one side and discharge to another side by volume change, a cylinder A is fitted on flanges C and check valves B are attached to the flanges as shown in a figure. The check valves are alternately operated to smoothly cause the suction and discharge. An electric or magnetic force is applied to the cylinder A to repeatedly deform the cylinder into a concave shape A' and a convex shape A" to change the capacity of the cylinder. As a result, a liquid or colloid is sucked from one side and discharged to another side. According to this constitution, wear due to a rotating or sliding portion is eliminated and a long lifetime is attained.

IPC: G06T1/00
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To easily generate a color conversion coefficient directly reflecting a limit with respect to an input device signal onto an output device signal. SOLUTION: A color conversion coefficient storage means 10 stores lots of color conversion coefficients such as a linear lookup table(LUT) conversion table, a 3×3 matrix, and a 3-dimension LUT color conversion table. An operation panel 40 designates plural color conversion coefficients to be linked and designates an address to revise a value of the 3-dimension LUT color conversion table providing the color conversion coefficient after linking and a value of a table after the revision with respect to the address. A color conversion coefficient link means 30 reads the plural designated color conversion coefficients from the color conversion coefficient storage means 10 and links them to generate the 3-dimension LUT color conversion table to convert RGB signals into yellow, magenta, cyan, black YMCK signals.  A color conversion coefficient revision means 20 revises a table value with respect to the designated address of the generated color conversion table into the designated table value.

Title: Manufacture of thin-film transistor
Inventor: OGAWA KUNI
IPC: H01L29/786
Filed: 1985-04-19
Abstract: PURPOSE:To stabilize characteristics while reducing OFF currents by forming a metallic impurity thin layer into a gate insulator layer and annihilating elec tron traps existing near the interface between a semiconductor layer and the gate insulator layer.

Title: Connecting device for electric apparatus
Inventor: HARUMOTO YASUMASA
IPC: H02B13/02
Filed: 1981-06-02
Abstract: PURPOSE:To prevent noises from an electric apparatus by a constitution wherein a part of a connecting tubular body positioned inside a soundproof wall is formed of a flexible joint having a smaller diameter than that of the part of the body positioned outside the wall. CONSTITUTION:Vibrations and noises delivered from the main body of a transformer are absorbed by a flexible joint 11 arranged inside a soundproof wall 2 and are not transmitted directly to a sound intercepting board 4, and therefore, the vibrations and noises inside the soundproof wall 2 do not leak outside the soundproof wall. Moreover, the diameter of the flexible joint 11 is made smaller than that of an intermediate connecting tubular body provided outside the soundproof wall 2. Since the cross-sectional area of a communicating part of insulating oil is reduced immediately before a place where it penetrates the wall 2, the amount of vibrations and noises propagated through the oil is reduced remarkably. Furthermore, the part penetrating the soundproof wall 2 requires no conventional sound-absorbing material for blocking up apertures around the penetrating part. Accordingly, the number of assembling processes can be reduced, while the passage of noises through this part is largely restrained.

IPC: G03D3/00
Filed: 1991-04-16
Abstract: PURPOSE:To perform the optimum replenishment of replenishment liquid when the replenishment liquid is replenished to the processing tank for development of the automatic developing machine according to the processed amount and secular change of a photosensitive material and to prevent the processing from being disabled owing to a drop in the temperature of processing liquid resulting from the replenishment of the replenishment liquid. CONSTITUTION:The deficiency of replenishment liquid, found according to processing conditions up to yesterday, from a minimum daily replenishment amount (MDR) found from the standard processing conditions of the photosensitive material is divided into daily operation time, which is added to processing replenishment or replenishment with time to replenish the liquid. The liquid is replenished by the deficiency based upon the MDR not at a time, but divisionally at the start of processing on the day, so the temperature of the processing liquid does not fall abruptly. Consequently, such trouble that the startup time for temperature adjustment becomes long is eliminated and a stable processing state can be maintained.

Abstract: PURPOSE:To provide an IMC controller capable of eliminating the necessity of readjustment even when an identification error exists in the idle time or time constant of an internal model mathematically expressing a controlled system process. CONSTITUTION:The 1st subtracting processing part 3 subtracts a feedback amount (e) from the output of an objective value filter part 2 to which an objective value (r) is inputted. A manipulated variable computing part 4 computes a manipulated variable (u) from the subtracted output and outputs the variable (u) to a controlled process. The 2nd subtracting processing part 8 subtracts a reference controlled variable ym outputted from an internal model output computing part 6b from the controlled variable (y) of the controlled system process to obtain the feedback amount (e). An idle time error detecting part 10 analyzes the controlled variable (y) stored in a controlled variable storing part 9, and when a model identification error exists in the idle time of an internal model, outputs a correction signal. At the time of outputting the correction signal, error-corrected idle time is outputted from an idle time correcting processing part 11 to an internal model storing part 6a to correct the idle time of the internal model.
