Title: Person detecting device
Inventor: TAKENAKA NAOFUMI
IPC: F24F1/02
Filed: 1990-05-09
Abstract: PURPOSE:To improve the responsiveness of the moving detection by outputting a person detecting signal at the time when the input value of infrared rays reflected by a person exceeds a threshold, and thereafter, outputting a person moving signal at the time when the input value becomes lower than a movement deciding value. CONSTITUTION:A light emitting means H emits infrared rays of a prescribed light quantity, and a light receiving means J receives its reflection and detects the input value of the infrared rays. Subsequently, when a person exists in front, an input value to the means J of infrared rays reflected from the person exceeds a threshold, and a person detecting means 101 outputs a person detecting signal. Next, a storage means 102 stores the infrared-ray input value in that case as an initial value, and thereafter, when the person moves and the input value to the means J becomes lower than a movement deciding value, a person movement detecting means 104 outputs a person moving signal. In this case, since a setting means 103 sets in advance a higher value of an initial value stored in the means 102 and a value obtained by subtracting a prescribed value from the threshold as a movement deciding value, a movement decision corresponding to an actual moving distance of the person is executed, and the responsiveness of the moving detection can be improved.

IPC: H01J9/24
Filed: 1983-07-01
Abstract: PURPOSE:To simplify operation control while doing with one worker and achieving laborsaving by forming slits to become the retreat of air when injecting adhesives on the cathode-ray tube proper. CONSTITUTION:Slits 7 are formed on four corner parts of the skirt part of the panel part constituting one part of the cathode-ray tube proper 1.
