A control system with a microprocessor controls an output pressure of a water/air pump and a light amount of a light source lamp in an endoscope. Under control of a program, the microprocessor periodically accesses a decoder to periodically generate a pulse signal. The generated pulse signal is applied to a watch dog type detector for detecting an abnormal operation of the microprocessor. When the...

A loop that can be easily attached to an electrical cord near the plug that will prevent accidental separation from said plug and another electrical cord plug when joined.

An implanting article which includes a base body composed of a mother material and a surface portion containing dispersed apatite particles. The base body and surface portion are formed in a mold by solidifying the mother material containing apatite particles under centrifugal force. The resulting implanting article has good mechanical properties because the base body scarcely includes apatite par...

A method of producing printing plates having microdots in nonimaged areas is disclosed.
