Abstract: An electromagnetic relay has a solenoid formed from a wound coil, a movable contact-point block having a movable iron core, an insulation holder integrated with the upper end portion of the movable iron core and a movable contact piece which is biased toward and supported by the insulation holder through a contact pressing spring, and a fixed iron core fitted in a through hole in a yoke. A restoring spring is inserted into an axial hole of the solenoid. The movable iron core of the movable contact-point block is slidably inserted into the axial hole of the solenoid from thereabove. The fixed iron core is inserted into the axial hole from therebelow. The movable iron core is adapted to be slid into the axial hole based on the magnetization force and the demagnetization of the coil to move the movable contact-point block back and forth.

Abstract: Disclosed is a conventional safety razor having a sounding board disposed immediately behind and approximately coextensive and even with the razor head, the sounding board being in the form of a thin plastic plate extending upwardly from the razor handle, with the plate serving as both a means for scraping hair stubble on human skin, as well as a means for audibly amplifying vibrations induced thereby. This alerts the user to the continued presence of objectionable hair stubble so that the shaving process is repeated with or without a change of safety razors or razor blades as required. Alternatively, a miniature solid-state microphone may be mounted on the safety razor for sensing the vibrations and driving an audio speaker through an amplifier/filter network.
