Abstract: A plastic wavelength shifting fiber includes a core containing a fluorescent agent having a peak of a fluorescence spectrum in a wavelength range of 430 to 550 nm, and a cladding covering an outer peripheral surface of the core and having a refractive index lower than that of the core. The number of carbonyl bonds in the fluorescent agent is one or smaller.

Abstract: In the hydraulic excavator, the control unit outputs the drive signals, which gives the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device to the work implement operating lever, the right work implement operating lever and the traveling lever, to the drive section. The control section outputs the control signals based on the motion of the left work implement operating lever the right work implement operating lever or the traveling lever operated by the operator when the motion of the left work implement operating lever, the right work implement operating lever or the traveling lever operated by the operator is different from the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device.

Abstract: A work vehicle includes an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever.

Abstract: A work vehicle includes a cab, a body frame and a restrictor. The body flame includes a base component, and a support frame provided on an upper side of the base component. The support frame supports the cab. The restrictor is provided to a floor frame of the cab. The restrictor is disposed between the base component and the floor frame. The restrictor includes a retaining member disposed on a lower side of the support frame, and an impact absorber disposed on a cab side of the retaining member.

Abstract: An antenna system comprises an antenna mounted on a vehicle, an amplifier for amplifying a radio signal received by the antenna, a light emitting part that converts the amplified radio signal into an optical signal and that outputs the optical signal, a fiber-optic cable that is installed in the vehicle and that is used for transmitting the optical signal, and a light receiving part that receives the optical signal transmitted through the fiber-optic cable, converts the optical signal to an electrical signal, and outputs the electrical signal.

Abstract: When a plug is to be fitted to a first connector from one side and a plug is to be fitted to a second connector from the other side of an optical coupling device, the first connector and the second connector shift in an X direction to ease stresses working on an internal optical fiber. Therefore, stresses working on the optical fiber can be eased without having to extend a length of the internal fiber, and accordingly it is made possible to reduce an overall size of the optical coupling device.

Abstract: A method for manufacturing plasma display unit substrates having bulkheads by applying a mixture of ceramic powder or glass powder and a binder to a back face plate made of ceramics or glass. Bulkheads are formed on the back face plate by rolling a roll, having a plurality of grooves on its surface, over the mixture-applied surface of the back face plate while applying pressure to the surface with the roll. Alternatively, the grooves on the surface of the roll may be pre-filled with the moisture and rolled over the surface of a back face plate, thereby forming bulkheads.

Abstract: A rotary head type magnetic recording/reproducing apparatus having two playback heads A' and B' for verifying the recorded condition after recording on a magnetic tape by two recording/reproducing heads A and B (read-after-write) by which any recording error is found immediately. Two playback heads A' and B' are mounted, respectively, at positions separated by 90.degree. around a rotational center axis relative to the recording/reproducing heads A and B along the head rotating direction. Heads A' and B' are mounted also deviating by a particular dimension relative to the recording/reproducing heads A and B, along a direction perpendicular to the head scanning direction. Since read-after-write is performed immediately after recording, any recording error is found almost simultaneously with recording, by performing read-after-write as in normal reading.

Abstract: An instant photographic apparatus uses a photosensitive member in the form of a roll, of a length to receive a plurality of exposures, and an image-receiving member in the form of either a roll or a sheet. The photosensitive member is cut off to the length of a single frame of film after the exposure of its leading end. Before or after cutting off the member or members, the exposed leading end of the photosensitive member and the image-receiving member are superposed. Between the superposed members a processing liquid is distributed and spread in a uniform layer for diffusion transfer processing. During the processing, negative and positive images are produced simultaneously on the photosensitive and image-receiving members, respectively, according to the latent image previously created on the photosensitive member by exposure.

Abstract: An image-receiving member of sheet material has a portion on which a positive image is adapted to be formed. A pod of processing liquid is secured to the sheet material outside of the image-forming portion. Each pod is preferably divided into two processing fluid containing portions, such that an advancing roller can contact the flat portion devoid of processing liquid in order to advance the image-receiving sheet without rupturing the pod. The mask defining the area on which a positive image is formed, can be either a continuous sheet having openings at regular intervals, or it can be formed by connector sheets alternately coupled to image-receiving sheets in combination with longitudinal masking strips affixed directly to the image-receiving sheet.

Abstract: A photographic apparatus for use with the peel-apart type self-developing film units contained in a cassette is provided for allowing a user to take a photograph of himself and obtain the print then and there. The apparatus includes a camera back which is moved forward for urging the cassette in order to locate photosensitive sheets of film units in the cassette in position for exposure and retracted from the cassette after, say, ten exposures. The camera back is kept retracted for a time sufficient to allow automatic supplying of a fresh film pack which is the foremost one of a plurality of film packs contained in a rack. The apparatus also includes a film unit withdrawing apparatus for automatically withdrawing an exposed film unit for providing the print to the user.
