Title: Catalytic layer of air electrode
Inventor: NAKAMURA TOSHIAKI
IPC: H01M4/86
Filed: 1981-11-10
Abstract: PURPOSE:To obtain a catalytic layer able to perform long=range heavy load discharge  and excellent in liquid leakage resistance by a method wherein both of an air=side  layer and an electrolyte-side layer carry at least either of a fluorine-contained solvent  or a perfluorocompound and besides the content ratio (weight %) of a water shedding  binder of said air-side layer is made to be bigger than the content ratio (weight %) of  said water-shedding compound of said electrolyte-side layer. CONSTITUTION:A perfluorocompound is used by solving it in a fluorine solvent. Thereby, the perfluorocompound is made to be in the range not less than 0.1% and not more  than 10% in the volume ratio to the volume of the fluorine solvent. The content ratio  of the water shedding compound inside of an air-side layer is made bigger than that in the electrolyte-side layer in the wt%. When said catalytic layer is applied to an air  electrode, electrolyte becomes unlikely to percolate through pores inside of the air-side  layer, while the electrolyte properly percolate through the pores of the electrolyte-side  layer so that in the interface of two layers or in the neighborhood thereof the perforation of the electrolyte and water shed maintain delicate balance so as to make a three- phase zone performing electrochemical reduction reaction of oxigen gas to have long- range stabilized existence.

Abstract: PURPOSE:To provide the blank material which has good workability, has adequate lightness, does not require a secondary treatment, such as plating, does not affect timbres and does not increase a cost by constituting the blank material of a Pt-Pd alloy consisting of Pd in a specific value range and the balance Pt. CONSTITUTION:This blank material consists of the Pt-Pd alloy consisting of 30 to 60% Pd and the balance Pt. The reasons why the content of the Pd is confined to 30 to 60% are as follows; there is no effect of the addition and the reduction of weight is not possible if the content of the Pd is below 30%; the material is so lighter than a material of karat gold that the material has no massive feel and gives an cheap impression and moreover, mechanical strength is not obtainable if the content exceeds 60% Pd. The blank material is provided with the tint of a unique platinum system by the Pt and is not impaired in the tint of the platinum system by the Pd. The characteristics of the material lighter in sp. gr. than the Pt are fully utilized and the reduction of the weight is attained. The blank material made of such Pt-Pd alloy for wind instruments permits working, such as material working, shape working to musical instruments, parts mounting so easy. Further, the blank material has the excellent corrosion resistance and chemical resistance without discoloration at the time of heat treatments and against environment and has good timbre as well.

A trouble model setting circuit 300 sets a model for the trouble discovered to generate a circuit description data for simulation. A trouble diagnosing simulator 200 executes a simulation to update a simulation data. This enables the separating of causes of the troubles one by one to diagnose using a simulation data considering effect of the troubles discovered thereby achieving a fast and accurate diagnosis of multiple troubles without the need for checking of all networks.
