  • Patent number: 5693174
    Abstract: An apparatus for attaching a molding to the peripheral edge of an article such as a glazing used in an automobile. A molding having a groove in its one side is extruded from an extruder. The molding is guided so that the leading end of the molding contacts the edge of an article which is held by a robot. The groove of the molding is expanded by a guide section, and the edge of the glazing enters the groove thus expanded. The robot then rotates the glazing, while pressure is applied to the molding so that the molding adheres to the glazing. When the glazing is rotated one turn, the molding is cut. The molding may be heated from the side having the groove, and cooled from the opposite side having a lip. This facilitates the attachment of the molding without causing any deterioration of the shape of the lip.

  • Patent number: 5140265
    Abstract: An eddy current flaw detecting endoscope apparatus has an endoscope having an elongate insertable part and an objective optical system provided on the tip side of the insertable part. A flaw detecting device is provided on the tip side of the endoscope. A signal processing device processes a signal for the flaw detecting device. An eddy current flaw detecting apparatus detects a flaw in an object to be inspected and generates a flaw detecting signal. A controlling device generates a control signal controlling a controlled device with a flaw detecting signal of the eddy current flaw detecting apparatus.

  • Patent number: 4901142
    Abstract: A video scope system including a video scope in which a solid state image sensor is disposed in a distal end of an insertion to be inserted into an object under inspection and picks up an image of the inside of the object under inspection illuminated by a light fed by a light guide extending in the insertion section, a light source unit having a light source feeding a light into the light guide, and a video processor unit processing a signal supplied from the solid state image sensor to output a picture signal to be displayed on a monitor. The light source unit and the video processor unit are disposed in separate housings, respectively, and these units are connected to each other by a cable to transmit a signal therebetween.

  • Patent number: 4879992
    Abstract: This rigid electronic endoscope has an endoscope having an elongate insertable part connected to the front part of an operating part which is also a holding part on the base side and formed of a solid state imaging device which can output an electric signal by electrically converting an object image in this insertable part and a conductive shielding member sheathing this insertable part. The electric signal obtained by this endoscope is input into a signal processing circuit. The ground terminal of this signal processing circuit is electrically connected to the above mentioned shielding member and is isolated from a ground terminal on the external current source side.

  • Patent number: 4870950
    Abstract: This endoscope system is provided with an endoscope and an image receiving apparatus to be fitted to the eyepiece part of this endoscope. The endoscope has an elongate insertable part, an objective optical system provided in the tip part of the insertable part, an eyepiece part provided on the rear end side of the insertable part and an image guide consisting of a fiber bundle transmitting the image formed by the objective optical system to the eyepiece part. The image receiving apparatus has an image receiving part of many pixels on which the image from the eyepiece part is formed. Further, the endoscope system is provided with a vibrating apparatus relatively vibrating the image formed on the image receiving part and the image receiving part. The image receiving apparatus is a television camera, co-viewing apparatus or electronic still camera.

  • Patent number: 4803550
    Abstract: An imaging apparatus for use in an electronic endoscope or the like is provided with a mechanically driven light-shielding plate, wherein imaging is effected by using a solid-state imaging device starting from a time when an amount of light shielded by this light-shielding plate becomes minimal, or imaging is effected repeatedly during a short exposure time within a transient period during which the amount of light shielded becomes minimal, and when an signal level of each image reaches a reference level, that signal is stored in a memory.
