Abstract: An optical lens device forms a condenser lens having a first lens of a positive focal length and a second lens of a negative focal length. The first and second lenses are stacked with their optical axis aligned. The first lens has a lens section, edge section and glass member having a linear expansion coefficient smaller than that of the lens section and the edge section to suppress shape change of the first lens due to temperature change of the first lens. The second lens, which is stacked with the first lens, is used for offsetting a change of the positive focal length generated in the first lens when the temperature varies. The glass member having a small linear expansion coefficient suppresses that shape change of the first lens which is not compensated by the second lens.

Abstract: A method for manufacturing a semiconductor device includes: preparing a first substrate; forming a metal film having a Ti layer as the most outermost surface on one surface of the first substrate a metal film having a Ti layer as the outermost surface; patterning the metal film to form a first pad portion; preparing a second substrate; forming on one surface of the second substrate a metal film having a Ti layer as the outermost surface; patterning the metal film to form a second pad portion; vacuum annealing the first substrate and the second substrate to remove an oxide film formed on the Ti layer in the first pad portion and the second pad portion; and bonding the first pad portion and the second pad portion together.

Abstract: A surface acoustic wave (SAW) sensor includes a surface acoustic wave material and a comb-teeth electrode. The surface acoustic wave material is to be arranged at a place where the surface acoustic wave material is distorted by physical quantity such as stress. The comb-teeth electrode is arranged on the surface of the surface acoustic wave material to excite a surface acoustic wave to the surface acoustic wave material. The surface acoustic wave material has a sapphire board and a ScAlN film arranged on a surface of the sapphire board.

Abstract translation: 光学透镜装置形成具有正焦距的第一透镜和负焦距的第二透镜的聚光透镜。 第一透镜和第二透镜以它们的光轴对准的方式堆叠。 第一透镜具有透镜部分,边缘部分和具有比透镜部分的线膨胀系数小的透镜部分和边缘部分的玻璃部件,以抑制由于第一透镜的温度变化引起的第一透镜的形状变化。 与第一透镜堆叠的第二透镜用于抵消当温度变化时在第一透镜中产生的正焦距的变化。 具有小线性膨胀系数的玻璃构件抑制未被第二透镜补偿的第一透镜的形状变化。
