Title: Ultrasonic measuring device for distance
Inventor: NAKAMAE FUJIO
IPC: G01S7/64
Filed: 1981-07-27
Abstract: PURPOSE:To enable easy recognition of the result of measurement by a method wherein a time required for receiving emitted ultrasonic waves is converted into a period wherein an intermittent sound having an audio frequency is repeated. CONSTITUTION:Ultrasonic waves are emitted from an oscillator 4 for transmission by the output pulses of a one-shot pulse generating circuit 9, while a bistable multivibrator 18 is set. The ultrasonic waves received by an oscillator 5 for reception are given as reset pulses to the bistable multivibrator 18 through the intermediary of an ultrasonic wave receiver 2. The output of the bistable multivibrator 18 is given to a load 6 of a buzzer or the like via a pulse width- voltage transducing circuit 17, a voltage-frequency transducing circuit 16 and a monostable multivibrator 15, and thereby an audio-frequency sound having a tone color corresponding to the distance of measurement is generated.

The valence of lanthanide ions in the insulator agrees with that of a metal component, to allow the ions to be buried by the stoichiometric substitution, esp. an insulating material is pref. epitaxially deposited on an Si (100 or 111) layer. A fluoride layer, e.g. is substd. by rare earth ions, such as Er or Nd to deposit on a wafer to make a light-emitting diode on Si. A current flow between a metal film deposited on the fluoride layer and Si substrate induces a strong and sharp spectrum emission by exciting the substd. lanthanide in this layer.
