Title: Metal scavenger
Inventor: HOSODA KAZUO
IPC: C09K3/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain a metal scavenger having low toxicity to organism and capable of safely treating waste water and solid waste by introducing a metal- scavenging functional group substituting an active hydrogen in an amide compound produced from a nitrogen-containing compound having substitutable active hydrogen atom bonded to nitrogen and a vinyl nitrile compound. SOLUTION: A metal-scavenging functional group (e.g. dithio-acid group) is introduced to the nitrogen atom of an amide compound produced through an amidine compound by the reaction of a nitrogen-containing compound having substitutable active hydrogen atom bonded to nitrogen (e.g. ethylamine) with a vinyl nitrile compound (e.g. acrylonitrile) by substituting the active hydrogen atom on the nitrogen atom. For example, the dithio-acid group can be introduced by reacting an amide compound with carbon disulfide. A metal scavenger having a salt of a dithio-acid group as a functional group can be produced by carrying out the reaction of the amide compound with carbon disulfide in the presence of an alkali.

Title: Apparatus for detecting combustion of engine
Inventor: TAKAHANE TETSUO
IPC: F02P17/12
Filed: 1987-10-06
Abstract: PURPOSE:To effectively prevent the adhesion of carbon to an optical fiber and to enhance the detection accuracy of a combustion state, by detecting the carbon adhesion amount to the lighting part of the optical fiber in a combustion chamber. CONSTITUTION:In order to detect the combustion light in a combustion chamber 3, the lighting part 20 of the side end part of the combustion chamber 3 of an optical fiber 21 is provided so as to be directly faced to the interior of the combustion chamber 3. The light signal introduced into a photoelectric converter 22 through the optical fiber 21 is converted to an electric signal showing the intensity and frequency (color) of the light signal to be inputted to a control unit 25 (ECU). When a carbon adhesion amount reaches a predetermined value or more, for example, the air/fuel ratio of a gaseous mixture is made leaner than that at a usual time by the control of the ECU 25 to make O2 excessive and the adhered carbon is burnt or combustion temp. is raised to burn the adhered carbon to remove said carbon from the optical fiber. By this method, the obstruction of the blocking of combustion light by adhered carbon is prevented and the enhancement of combustion state detection accuracy is achieved.

Abstract: PROBLEM TO BE SOLVED: To improve electric and optical characteristics, thermal stability, adhesion property and magnetic characteristics of a magnetic recording medium by forming a diamond-like carbon DLC film on a magnetic layer and adding Si into the film essentially comprising carbon. SOLUTION: A DLC film having SP<3> bonds or a film essentially comprising carbon is formed on a magnetic layer and elements of Si and Ge are added by <=20at.% to the carbon of the DLC film or the film essentially comprising carbon. Thereby, C-C bonds are decreased while C-Si and Si-Si bonds increase to make the film similar to a Si film. The hardness of the film decreases while the coefft. of friction increases. The DLC film contains 10 to 60at.% hydrogen which acts as a terminator for unbound hands to improve electric and optical characteristics and thermal stability of the film. By adding B, Al, Ga, N, P and As to the DLC film, the inner stress of the film can be relaxed to improve adhesion property. Thus, by forming the DLC film, magnetic characteristics can be improved.
