Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple molecules separated by whitespace or by comma.

- 縦筒型の埋設タンクの構築方法において、埋設する筒体の下縁に当該筒体より周寸法の大きなガイド枠を固定し、前記筒体の外側でかつ
掘削する穴の周縁を画定する前記ガイド枠の外周壁より内側でかつ前記筒体の外側である前記外周壁と前記筒体との間に、下端が前記外周壁の内側に開口する複数本の排水パイプを前記筒体に沿わせた状態で立設し、当該排水パイプの上端に排水ポンプを接続し、前記外周壁より内側となる穴の底面を掘削して所定の深さまで前記ガイド枠及び筒体を沈下した後、前記排水パイプの下端が埋設される深さに砕石層を設け、タンクの底板、頂板及び上載荷重となる層を形成し、前記排水ポンプを取り外して排水パイプの上端を開口状態とすることを特徴とする、埋設タンクの構築方法。 - 外周壁を備えたガイド枠と、このガイド枠より周寸法の小さい筒体であって当該ガイド枠上に下縁を固定された縦筒型の筒体と、下端を前記外周壁の内側に開口させて前記筒体の外側でかつ前記外周壁より内側である前記外周壁と前記筒体との間に前記筒体に沿わせた状態で立設された複数本の排水パイプと、前記外周壁の内側に前記排水パイプの下端が埋設される深さで形成された砕石層と、前記筒体の下端部に周縁を溶接されて当該砕石層の上方に位置する底板と、前記筒体の上端部に周縁を溶接された頂板と、この頂板上の上載荷重となる層とを備えている、埋設タンク。
