Abstract(J)	超音波モータは,特徴の一つとして静粛性が有り車のヘッドレスト用アクチュエータとしても使用されている.しかし数ミクロンの超音波振動を摩擦を介して回転力に取り出している為,効率が電磁モータに比べ低い.今回ステータとロータの摩擦接触部に着目し,効率を向上させる櫛歯形状についての試作と試験結果を報告する. Translation
Abstract(E)	The improvement of silence is a key factor in the development of car. Ultrasonic motor has been applied for seat actuator because of its silent ability. Moreover it has been used for some manufactures in practical level, because it has many special merits. However, its efficiency(output/input) is lower in general, and it is necessary to improve this point. Stator shape was considered as an important factor to improve its efficiency. For that reason the original stator which has slant slits was made. It has contributed in the improvement of efficiency.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
