Title: Dome type noctovision camera
Inventor: SAKURAI HIDEMASA
IPC: G08B13/181
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain a camera which does not require much time for assembly, which realizes night viewing by radiating infrared rays to a monitoring area and which is hardly recognized by a monitoring object by forming at least the infrared irradiation part of a dome type container of resin which does not transmit visible light but transmits infrared rays. SOLUTION: In this dome type noctovision camera, an infrared light emitting diode 5 is housed in a camera part housing case 6 constituting the dome type container with a lower case 2, and the infrared rays are radiated to perform night viewing. In the camera, the outer periphery of the dome type container is covered with a cover formed of resin which does not transmit the visible light but transmits the infrared rays. Therefore, the visible light is not leaked to the outside even when the diode 5 is lit, so that the monitoring object does not recognize that the noctovision camera is actuated even in the dark. A hole for an infrared light emitting diode need not be formed on the camera part housing case, and the camera part housing case is easily produced, then the hole and the light emitting diode need not be aligned in the case of assembly.

Filed: 1979-09-03
Abstract: PURPOSE: To exercise rotation control over a motor with high precision output signals of two flip-flops, for detecting which is greater between a reference pulse width signal and control signal, and its AND result.  
     CONSTITUTION: Input pulse width signal Tin is inputted to gate G 1 , and reference pulse width signal Tref to gate G 2 . Gates G 1 WG 4  generate inverted signals of Tin and Tref. Signal Tin is applied to input D of D type flip-flop FF 1  and clock ϕ of D type flip-flop FF 2 , signal Tref to clock ϕ of FF 1  and input D of FF 2 . When signal Tin>Tref, FF 1  reads the high level of Tin because Tref rises at fast timing, and FF 2  reads the low level of Tref. Thus, the rotating direction of the motor is determined. The rotation of the motor is inhibited for period Tin+Tref and allowed only when there is the difference between Tin and Tref twice continuously.
