    摘要: A double-wrap dry scroll vacuum pump for use as a vacuum pump for nuclear power equipment. The pump has a pump body including a suction port capable of being communicated with a vessel to be evacuated and a discharge port for discharging wrap compressed gas to an outside of the pump body after an operation of gas compression by the progressive volume reduction of a sealed space, formed by a revolving scroll and a pair of stationary scrolls. The pump further includes a pair of enclosing members which cover opposite end portions of a drive shaft and are mounted in a gas-tight state around the revolving scroll. The pump has compressed gas feed ports for feeding compressed gas therethrough to the enclosing members, the compressed gas having a higher pressure than the wrap compressed gas and is discharged together with the wrap compressed gas through the discharge port. To attain high performance and durability, the double-wrap dry scroll vacuum pump has a gas bearing in fluid communication with the compressed gas feed ports to rotatably support the drive shaft. A contact-less torque transmission means is implemented for transmitting torque from a driving source to the drive shaft.

    摘要: A viewfinder optical system for a real-image type viewfinder has a positive objective lens system for obtaining a finder-image, and an erecting optical system for converting the finder-image into an erected image. The erecting system includes a mirror for deflecting an optical axis of the objective lenses, and at least a part of the mirror is formed as a light-transmitting area. The viewfinder optical system further comprises an ocular lens for viewing the finder-image, and an optical system for optically producing an information pattern, such as a viewing-field-frame, to be superimposed on the finder-image. The projecting system includes a projecting lens which focuses and forms the frame-pattern on an image-forming plane, defined by the objective lens system, through the light-transmitting area of the mirror, so that the frame-pattern is superimposed on the finder-image.

    摘要: An electro-developing type camera using an electro-developing recording medium on which an image is developed while an electric voltage is applied thereto. The image is read out from the electro-developing medium by a scanning mechanism. A color separation filter is disposed in front of the recording medium, so that R, G and B images are recorded on first, second and third recording areas, respectively. The color separation filter and the recording medium are disks rotatably provided. A photographing optical system is disposed at a first position at which the optical axis thereof is positioned above the rotational axes. The scanning mechanism is disposed at a second position at which the scanning mechanism is positioned under the rotational axes of the electro-developing recording medium and the color separation filter. Each of the recording areas is positioned above the rotational axes when a photographing operation of the recording area is carried out, and is positioned under the rotational axes when a reading operation of the image from the recording medium is carried out.

    摘要: A casing of an optical reader comprises a reading head and a handle. The reading head includes a frame portion having a bottom opening of a parallelogram. A first switch and a second switch are provided on the frame portion, adjacent to the bottom opening. The first switch and the second switch are placed symmetrically and diagonally about the center of the bottom opening. When the first switch and the second switch are pressed and the tip ends of them become flush with the frame portion, they are turned on. The optical reading is controlled in accordance with the combination of the signals outputted from the first and second switches.

    摘要: Disclosed is a range finder system which includes a virtual image type first optical system for observing an object, and a second optical system for electronically capturing image of at least a part of the object. The range finder system is provided with an LCD (liquid crystal display) which displays the image captured by the second optical system. The image displayed on the liquid crystal display is directed to the virtual image type finder optical system, and the image as displayed on the LCD is combined with the image observed through the first optical system. Thus, two images are observed by a photographer as superimposed. A display controller controls the LCD so that the degree of coincidence of the superimposed images is varied in the direction of a base length based on an object distance information.
