IPC: G05B11/36
Filed: 1992-04-27
Abstract: PURPOSE:To attain the design of a servo system for controlled system of an I/O object having an integration characteristic by H<infinity> control. CONSTITUTION:A new controlled system calculating means 42 removes an integration characteristic (s) from the transmission function P(s) of an original controlled system and calculates P'(s) by adding 1/(S+alpha) to the P(s). Then a control device calculating means 43 finds out the transmission function C'(s) of a control device based upon a weight function W1(s) for sensitivity specified by a sensitivity characteristic specifying means 44 and a weight function W2(s) for complementary sensitivity. The transmission function C'(s) is expressed by C'(s)=((S+alpha)/S)C(s) due to the property of a mixed sensitivity problem. A new control device calculating means 45 extracts only C(s) by removing (S+alpha)/S from C'(s) based upon the relation f P(s)C(s)=P'(s)C'(s) and sets up the extracted value as the transmission function of the final control device.

Title: Combustion control device
Inventor: TOUDOU KENJI
IPC: F23N5/20
Filed: 1982-06-25
Abstract: PURPOSE:To allow an integrated circuit having a pre-purge function to be used substantially without actuating the pre-purge function, by arranging a digital type combustion control device such that a high frequency clock pulse as generated by an astable multi-vibrator is inputted into an integrated circuit for controlling a combustion in a hot water boiler and the like. CONSTITUTION:An integrated circuit 11 starts functioning to count the clock pulse of input terminal 11C, that is a pre-purging time upon a hot water temperature being lowered to a preset value. Because an output terminal 11g is in a high level at this moment, a high frequency clock pulse is inputted by an astable multi-vibrator 31, and thereby terminating the pre-purge in an extremely short period. Thereafter, when a safety timed duration is started for driving a fuel valve and an ignition device, the output terminal 11g enters into a low level and a power source to the astable multi-vibrator 31 is interrupted. As a result, there takes place the input of clock pulse generated by a bridge diode in response to the frequency of alternate power source 1 and a preset safety timed duration is obtained. In this manner, it is made possible to avoid the hunting of discharged hot water temperature which would otherwise occur due to an ignition delay.

IPC: H03J7/18
Filed: 1980-08-04
Abstract: PURPOSE:To prevent erroneous decision of a reception level by permitting the deciding operation of a reception-level deciding circuit only during the output period of a reception-state signal. CONSTITUTION:Under the command of a channel selector 12, a control circuit 10 varies the tuning voltage of a tuning-voltage generating circuit 7. Once detecting the reception level of an intermediate-frequency amplifying circuit 3 exceeding a prescribed value, a stop circuit 8 outputs a negative pulse (stop signal) showing a narrow-band reception state, and it is inverted by an inverting circuit 9 to apply the resulting signal to the control circuit 10. Then, the control circuit 10 stops variations in tuning voltage. Further, the output of a signal meter driving circuit is led to a reception-level deciding circuit to be compared with reference potentials 16 and 17, and the deciding operation is enabled through the operation of a diode 15 only when the stop signal is present.

Title: Method denaturing surface of base material to bacteria repulsiveness and blood compatibility, product having such surface and use therefor
Inventor: ANDERS CHRISTINE DR
IPC: A01N59/02
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To treat the surface of a base material without changing the mechanical strength of the treated material or without the occurrence of other serious defects by acting SO2 -plasma on the hydrophilic surface of the base material in order to denature the surface of the base material to bacteria repulsiveness and blood compatibility. SOLUTION: At the time of acting the SO2 -plasma on the hydrophilic surface of the base material, the surface of the base material and above all high-polymer plastic base material, may be denatured to the blood compatibility simultaneously with the bacteria repulsiveness. The denatured surface lowers the adhesion and propagation of bacterial at a high degree for a long period of time. As a result, the products having the denatured surfaces are adequate for many applications where the avoidance and suppression of the bacterium adhesion and growth are important. Then, the products are particularly adequate for, for example, hygiene, industry and foodstuff industry and biological technology as well. The products are particularly adequate for medial treatment when the blood compatibility simultaneously with the bacteria repulsiveness are important.

Title: Production of particle-dispersed material
Inventor: OSAWA YOSHIAKI
IPC: C22C1/10
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To uniformly disperse fine particles into a material by mixing powder obtd. by previously mixing and alloying addition particles with the powder of metal or the like to form a base metal to the molten metal of the base metal. SOLUTION: As for this method, the addition particles of ceramic or the like and the powder of metal or alloy to form a base metal or the powder of metal or alloy easy to alloy with the base metal are mixed by a mechanical alloying method using a ball mill or the like, and the mechanically mixed and alloyed powder or pellet is added to the molten metal of the base metal while being stirred. The average particle diameter of the addition particles may be regulated to <=10μm, and, in the case they are dispersed into the molten metal, since the moving rate of the particles is inversely proportional to the square of the particle diameter even if there is a difference in density in accordance with the Stokes' law, the separation of the particles and the molten metal is small even in a melted state for a long time compared to the case of rough particles.  Thus, as in the conventional manner, the material in which the particles are uniformly dispersed can be obtd. by the above melting method without adding a third metal to the base metal or executing surface treatment to the addition particles.
