Abstract:
A cylinder head cleaning method capable of cleaning a cylinder head with an enhanced foreign matter removing rate. The method is used to clean a cylinder head having therein a water jacket including a narrow space portion having a narrow flow path and a large space having a flow path wider than the narrow space portion, and the cylinder head further including holes communicating with the water jacket. Cleaning nozzles are inserted into the water jacket from the holes selected from the holes, clearing liquid is ejected from the cleaning nozzles toward the narrow space portion, and the cleaning liquid flowing from the narrow space portion to the large space is discharged to the outside of the cylinder head from the hole communicating with the space.
Abstract:
A composition for forming an n-type diffusion layer includes a glass powder containing P2O5, SiO2 and CaO and a dispersion medium. An n-type diffusion layer and a photovoltaic cell element having an n-type diffusion layer are produced by applying the composition for forming an n-type diffusion layer on a semiconductor substrate and by subjecting the substrate to a thermal diffusion treatment.
