  • Self-lighting type push button input device
    Patent number: 7266194
    Abstract: A self-lighting type push-button input device according to the presently disclosed subject matter can include a button base portion formed of a transparent material. Holes can be formed in predetermined positions of the button base portion, and spring portions can be formed integrally with the holes by molding transparent silicone rubber with a light diffusing agent incorporated therein. The button base portion serves as a light conducting portion, and the spring portions can uniformly diffuse the light distributed thereto by the light conducting portion, whereby lighting can be effected by a reduced number of light sources, effecting a reduction of size and cost.

  • Shell-and-tube type heat exchanger and method for production of (meth) acrylic acid by use of the exchange
    Publication number: 20070034363
    Abstract: A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.
