  • Patent number: 9787955
    Abstract: In a multi-projection device, each of the projectors comprises a light shielding plate. The light shielding plate has an end formed into a sawtooth shape and is also provided with a gradation coated part which is coated such that white-light transmittance gradually decreases in the direction away from the end.

  • Patent number: 7922822
    Abstract: A cleaning and sterilizing method for removing organic matter adhered to the surface of an endoscopic camera instrument, and effectively exhibiting bacteria-killing and virus-killing effects of acidic water uses, as a cleaning bath, an alkaline-water-producing electrolysis bath partitioned by a separating membrane and having electrodes on both sides, and conducts preliminary cleaning of an endoscopic camera instrument inserted in the cleaning bath by ultrasonic cleaning with city tap water. Subsequently, saline solution is provided to the electrolysis bath to conduct electrolysis, conduct ultrasonic cleaning with alkaline water obtained by the electrolysis, introduce acidic water in the acidic water generation bath and conduct sterilization-cleaning, and further to conduct ultrasonic cleaning with city tap water. Then, the endoscopic camera instrument is dried with warm air as the case requires.

  • Publication number: 20020037150
    Abstract: During a period of a burst signal that controls a color in a video signal, a signal having the reverse phase and double the amplitude of the burst signal is added to superpose the signal on the burst signal by less than some cycles of the burst signal. A processed burst signal thus made is recorded on the magnetic tape. And, when reproducing the magnetic tape, a color signal detection circuit of a TV monitor is not influenced to reproduce a normal picture image. And, the color signal detection circuit of a video tape recorder is influenced to malfunction, which prevents a correct recording. To reproduce a magnetic tape duplicated by the video tape recorder by the TV monitor will present an abnormal picture image. Thus, the invention intends to prevent an unfair duplication, by making the color of the picture image abnormal in the unfair duplication.
