Inventor: OODO SHIYUUICHI
IPC: C22B58/00
Filed: 1980-06-25
Abstract: PURPOSE: To take out high purity In from an In-contg. substance even if the Fe concn. of the substance is high by dissolving the substance in sulfuric acid, carrying out sulfurization, separating and removing solid matter, and adding Zn to reduce In.  
     CONSTITUTION: A substance contg. In together with other metallic components is dissolved in sulfuric acid to prepare an indium sulfate soln. After separating the dissolution residue, by blowing gaseous H 2 S or adding NaHS, sulfurization is carried out to precipitate most of metallic components such as Cd, As and Tl remaining in the soln. as sulfide, and the sulfides are separated. The resulting soln. contains much Fe 2+  in general, so the soln. is reduced at ordinary temp. while adding zinc duct under agitation until the oxidation-reduction potential of the soln. reaches a prescribed value, whereby In is reduced selectively and precipitated in the form of metal. Since Fe and other metallic components are not precipitated, high grade In mud can be obtd. by separation.

Abstract: PURPOSE: To reduce deviations of amount of filled up air among cylinders of an engine by constituting a suction system for the engine such that each of two suction pipes is further branched into two branch pipes and ignitions in cylinders communicated with these branch pipes are equally displaced from each other in phase by a crank angle of 180°.  
     CONSTITUTION: First and second suction pipes 4, 5 branched from a suction port 3 are further branched to first branch pipes 6, 8 and second branch pipes 7, 9, respectively. Then, eight cylinders including right bank cylinders 1 and left bank cylinders 2 are classified into odd numbered and even numbered ignition order groups C, D. Cylinders I, III of the C group are connected to the first branch pipe 6 while cylinders V, VII are connected to the second branch pipe 7. Further, cylinders IV, VI are connected to the first branch pipe 8 while cylinders II, VIII are connected to the second branch pipe 9. Thus, as all the four cylinders of each of left and right cylinder banks effect their suction strokes which are equally displaced from each other in phase by a crank angle of 180°, pressure vibrations in both suction pipes 4, 5 correspond to four equally displaced main pressure vibrations and hence deviations of amont of filled up air among the cylinders can be eliminated thereby.

Title: Heat generation indication device and its use
Inventor: KADOWAKI KAZUNORI
IPC: G01K5/50
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a heat generation indication device, which detects with high sensitivity, by providing heat recoverable member and a heat insulating cover and bonding at least one of them to an heat generating body. SOLUTION: A heat generation indicating device is bonded to a device at bonding agent layers 41 and 42 for use. This bonding work is so done that a heat insulating cover material 2 does not restrict thermal deformation of a thermal recoverable member 1. When the device generates heat because of over current, the generated heat is propagated from the device to the heat recoverable member 1, and the thermally recoverable member 1 shrinks as the member 1 is heated, so that protruding length L of the heat recoverable member 1 above the heat insulating cover material 2 shrinks, as a result, heat generation of the device is detected.  At this time, since release of the heat, propagated from the device to the heat recoverable member 1, to the surrounding air is suppressed well with the heat insulating cover material 2, the heat recoverable member 1 is efficiently heated, so that heat generation of the device is detected with high sensitivity.
