difference of expansion coefficientとは 意味・読み方・使い方

The sealing thin film is a very thin member and formed through low-temperature processes, so that even when there is a difference between the coefficient of thermal expansion of the sealing thin film and the coefficient of expansion of the substrates, stress applied to the functional element due to the difference of the coefficient of thermal expansion can be reduced as much as possible.例文帳に追加

封止薄膜は、非常に薄い部材であり、低温プロセスによって形成するため、封止薄膜の熱膨張係数と基板の膨張係数とに差がある場合でも、熱膨張係数の差に起因して機能素子に加わる応力を極力低減させることが可能となる。 - 特許庁

The paper has a relatively small difference for the coefficient of thermal expansion from that of silicon, so that warpage due to temperature variation is prevented.例文帳に追加

紙はシリコンと熱膨張率の差が比較的小さいので、温度変化による反りが防止される。 - 特許庁

Since there is difference in coefficient of linear expansion even if the outer rotor 4 and the main body 15 of the inner rotor 5 are made of an iron and steel material, reduction action of a tooth tip clearance at high temperature time is achieved by the difference in coefficient of linear expansion.例文帳に追加

アウターロータ４とインナーロータ５の本体15は、鉄鋼材料であっても線膨張係数に差があるため、その線膨張係数差によって高温時における歯先隙間の減少作用を得る。 - 特許庁

The difference of the thermal expansion coefficient of the honeycomb carrier and the catalyst coat of the exhaust gas cleaning catalyst is limited to three times or less of one of them.例文帳に追加

排ガス浄化触媒のハニカム担体と触媒コートの熱膨張係数差を一方の３倍以内に抑える。 - 特許庁

Because the coefficient of linear thermal expansion is small, even if subjected to heat cycles repeatedly, large stress due to the difference in the coefficient of thermal expansion with regard to an external board 210 does not occur.例文帳に追加

線熱膨張係数が小さいため、熱サイクルを繰り返し受けた際にも、外部基板２１０との熱膨張率差による大きな応力が発生しない。 - 特許庁

To solve a problem wherein a great stress is generated in solder joint of components, because a difference between a linear expansion coefficient of other component and a linear expansion coefficient of a substrate gets large, even when making small a difference between a linear expansion coefficient of a component and the linear expansion coefficient of the substrate, when the components different in the linear expansion coefficients are mounted, in an electronic circuit exposed to a wide temperature range.例文帳に追加

広い温度範囲に晒される電子回路においては、線膨張係数の異なる部品が実装されていると、いずれかの部品の線膨張係数と基板との線膨張係数の差を小さくしても、他の部品の線膨張係数と基板との線膨張係数の差は大きくなってしまい、そのはんだ接合には大きな応力が生じてしまう。 - 特許庁

To provide a ceramic member in which the difference between the coefficient of thermal expansion of an insulating ceramic and the coefficient of thermal expansion of a conductive ceramic is very small, and a mismatch by the thermal expansion difference and failures including breakage, cracking, peeling, and destruction can hardly occur.例文帳に追加

絶縁性セラミックスと導電性セラミックスとの間の熱膨張率差が極めて小さく、この熱膨張差によるミスマッチが生じる虞がなく、破損やクラックや剥離や破壊等の不具合が生じる虞がないセラミック部材を提供する。 - 特許庁

Further, the difference between the coefficient of the linear thermal expansion of the first polyimide system resin layer 3 and the coefficient of the linear thermal expansion of the second polyimide system resin layer 5 is less than or equal to 3×10^-6/K.例文帳に追加

そして、第１のポリイミド系樹脂層３の熱線膨張係数と第２のポリイミド系樹脂層５の熱線膨張係数との差が、３×１０^−６／Ｋ以下である。 - 特許庁
