Abstract(E)The automotive industry is required to reduce CO2 emissions. It must reduce CO2 emissions from Vehicles and production plants. To achieve more efficient combustion in internal combustion engines, the structure of a water jacket in a cylindrical head is complex. Simultaneously, a thin-walled cylinder head is required for vehicle weight reduction to achieve better fuel economy. The development of a die-cast method that can balance these two issues at a high level is urgently needed. This report will explain the details of the vacuum low-pressure die-cast (V-LPDC) process and related technologies developed for these products.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
