Title: Control method of servo controller
Inventor: ARIMOTO TAKU
IPC: G05B13/02
Filed: 1984-07-24
Abstract: PURPOSE:To improve the safety and quick responsiveness and also the tracking performance of servo by obtaining the dynamic characteristic of a servo controller and a controlled system, calculating an input signal so as to obtain a desired output signal based on the dynamic characteristic and using the signal so as to control the controlled system. CONSTITUTION:When any two signals among an input signal (u) from a digital computer 1, an output signal (f) detected by a detector 7 and the dynamic characteristic of the servo controller and the controlled system such as an impulse response (g) are given, the remaining signal is calculated in general. Then a digital computer 1 generates a specific input signal at a timer region, e.g., a proper test signal u1 to control the controlled system 6, an output signal f1 detected by a detector 7 in response to the u1 is stored in a memory 9 via an A/D converter 8, then the impulse response (g) is obtained. Similarly, an input signal u2 obtained taking the dynamic response of the servo controller and the controlled system into consideration is generated from the computer 1 from the impulse response (g) and the objective output signal f2, and the controlled system 6 is controlled, then the output signal f2 coincident with the object output signal is obtained.

Abstract: PURPOSE:To obtain a Pt alloy catalyst having high dispersibility and high activity by depositing Pt on a carrier and adhering a metal compd. for forming an alloy on said carrier, followed by heat-treating said metal compd. in a reducing atmosphere to reduce the metal compd., and by heat-treating it in an inactive gaseous atmosphere to form the alloy thereof. CONSTITUTION:The Pt metal is deposited on the carrier such as acetylene black, etc., by means of a liquid phase reducing method, etc., and then, the Pt catalyst is dispersed in an aqueous solution of a water-soluble salt of the metal for forming the alloy such as iron nitrate, etc. Subsequently, the metal is deposited on the Pt catalyst in a form of the metal oxide, followed by drying and crushing the metal oxide. The obtd. catalyst is heated at a temp. of 200-350 deg.C, while flowing a mixed gas of gaseous nitrogen and gaseous hydrogen, thereby completely reducing the metal compd. And, the formation of the alloy is carried out by changing the gas to a pure gaseous nitrogen. As the metal compd. is already completely reduced to the metal, the heat-treating temp. may be reduced to about 850-900 deg.C, whereby the metal compds. are completely formed to the alloy thereof, and the alloy is highly dispersed. The Pt alloy catalyst having high activity and good durability and an excellent anti-toxicity property is obtd.

IPC: H04N19/00
Filed: 1989-06-21
Abstract: PURPOSE:To decrease the number of picture element data lines, to reduce a circuit scale and power consumption and to reduce manufacture cost by convoluting a valid picture element data onto a thinned picture element data position. CONSTITUTION:In the case of reproducing an interpolation picture element by L line such as 3 lines, the picture element data interleaved by 2X3-1=5 lines (line n-2, n-1, n, n+1, n+2) is multiplexed into 3 lines, i.e., lines n-2/n-1, n/n+1, n+2/n+1 by convoluting the picture element data to the position of the interpolated picture element among lines. In the case of reproducing the interpolation picture element by line n-1, a coefficient is multiplied with multiplexed 7-picture element data by line n-2/n-1 and a coefficient is multiplied with multiplexed 3-picture element data by line n/n+1 and the sum is used as the interpolation picture element data to be convoluted onto the picture element position. That is, multiplexing is applied. Thus, duplicated line n-2/n-1 is reproduced as the line n-1 including the interpolated picture element. Thus, the circuit scale is reduced, the power consumption is decreased and the manufacture cost is reduced.

IPC: H01L21/52
Filed: 1991-06-27
Abstract: PURPOSE:To perform a precision plane adjustment wherein a face subjected to a pressurization force is not turned inside a horizontal plane by using the following: a functional spring which supports a member subjected to the pressurization force; and a support which is arranged in its center. CONSTITUTION:The title mechanism is provided with the following: a stage 14 formed of a member which supports a substrate 13 on which a semiconductor chip 12 is mounted, i.e., which is subjected to a pressurization force; a functional spring 15 which supports the stage 14; and a support 16 formed of a rigid body which is situated in the center of the functional spring 15. Since the functional spring 15 is shaped to be symmetric with respect to an axis, its pressurized face is not turned even when it is compressed by a load. As a result, when it is used in a semiconductor assembly apparatus and the parallelism of the face of a bonding tool 10 with an electrode pattern 13a becomes out of order, the side of the bonding tool 10 is lowered and one point of a lead 12a comes into contact with the electrode pattern 13a, the functional spring 15 directly under this part is compressed and the substrate 13 is lowered. Thereby, the mounting accuracy of the semiconductor chip 12 can be made good when the chip is mounted on the substrate 13.
