    • A surface mounting quartz crystal oscillator has an IC chip containing an oscillator circuit, and a quartz crystal unit which are sealed in a container body by a metal cover, wherein stray capacitances C1, C2 are equivalently in parallel with oscillation capacitors Ca, Cb connected to one and the other ends of the crystal unit, respectively. A gap between the IC chip and a crystal blank of the crystal unit, and a gap between the crystal blank and metal cover are set in accordance with a changing amount of the oscillation frequency due to a change in the stray capacitances C1, C2 in a direction in which a change in equivalent series capacitance is reduced, as viewed from the crystal unit, while maintaining a spacing between the IC chip and metal cover.

    • The invention relates to a cylinder head for an internal combustion engine in which each combustion chamber has a prechamber. A cast metal body of the cylinder head has recesses each of which provides a prechamber, and a hollow and, for example, bell-shaped member of a porous ceramics is cast-inserted in the inner surface defining each recess. Use is made of a ceramics low in thermal expansion coefficient and heat conductivity, such as aluminum titanate or cordierite, and the porosity of the ceramics is 5 to 50%. Because of its porousness the cast-inserted ceramics member is easily machine-finished. After that, for enhancement of strength and durability, the cast-inserted member of the porous ceramics is impregnated with an inorganic refractory material by using either a solution of, for example, sodium silicate or aluminum phosphate or an aqueous suspension of a ceramics powder, or a mixture of the solution and the suspension.
    • 本发明涉及一种用于内燃机的气缸盖,其中每个燃烧室都具有预燃室。 气缸盖的铸造金属体具有各自提供预制室的凹部,并且多孔陶瓷的中空的,例如钟形的构件被铸造插入到限定每个凹部的内表面中。 使用的陶瓷的热膨胀系数和导热系数低,如钛酸铝或堇青石,陶瓷的孔隙率为5〜50%。 由于其多孔性,铸造陶瓷构件容易机加工。 之后,为了提高强度和耐久性,通过使用例如硅酸钠或磷酸铝的溶液或陶瓷粉末的水性悬浮液,多孔陶瓷的铸造插入构件用无机耐火材料浸渍, 或溶液和悬浮液的混合物。

    • The present invention is directed to a variable distortion aberration image pickup device that is capable of varying distortion aberration with its center at any desired point either inside or outside an image where, specifically, distortion aberration is effectively developed and/or eliminated with the distortion center at any desired point both inside and outside the image as desired, and such an image pickup device is also capable of varying distortion aberration with its center at a desired point either inside or outside the image, separately in individual directions, where specifically an image is processed so as to have distortion aberration with its center at any desired point both inside and outside the image, with varied distortion ratios from one direction to another. For that purpose, the variable distortion aberration image pickup device is comprised of a photograph lens, two-dimensional opto-electronic feedback elements, and a distortion aberration conversion circuit that receives output image signals from the two-dimensional opto-electronic feedback elements to dislocate a desired point of an image in some direction(s) from the given center of distortion.
