  • Publication number: 20020187349
    Abstract: The disclosure is for an improved film coating useable on optical media molds and the apparatus for and method of making such a film. The film is a diamond-like carbon layer of 0.3 to 3.0 microns coated on a titanium underlayer of 0.1 to 1.0 microns. The method of making the diamond-like carbon film is to deposit a defect free underlayer coating on to the steel substrate of the mold using an electron beam coating apparatus that has a hollow cathode electron beam generator and a rotating crucible containing the coating material. The diamond-like carbon film is then produced on top of the underlayer coating.

  • Patent number: 5983033
    Abstract: A lens barrel permits easier switching of an extending operation between a setup operating region, which begins at a collapsed position where the lens frame of the lens barrel is retracted, and a zooming region, and accordingly provides a simpler mechanism. In the setup operation, a setting gear is driven to extend a setting frame, a float key, and a moving frame so as to extend a first group zoom frame retained on a cam frame and a second lens holding frame from a collapsed position to a photographing standby position. In the zooming operation, a zoom gear is driven to rotationally drive the moving frame so as to adjust the first group zoom frame and the second lens holding frame.

  • Patent number: 5649251
    Abstract: In a camera of this invention, a lens barrel including a photographing lens built therein and an aperture opening formed in a camera body are coupled to each other by a light-shield unit in a light-tight manner. The light-shield unit comprises a bellows member made of rubber, sheet, cloth or other material capable of shielding light, which is folded to have top and bottom creases in the spiral form, and a spiral skeleton member comprising a linear spring and fitted to the inner side of a portion of the bellows member which defines the top crease. The skeleton member prevents a flexion of the bellows member, thereby preventing the bellows member from interfering with the flux of photographing light coming through the lens.

  • Patent number: 5379084
    Abstract: In a camera according to the present invention, a driving source is driven using a zoom switch to adjust a focal distance value of a zoom optical system. In the meantime, a range finding unit measures a range to a subject. After zooming by means of the zoom switch is completed, an arithmetic logic unit serving as a focal distance determining unit and control computes the range finding value and the focal distance value to obtain a magnification for imaging a subject on film. A picture size selecting unit provides the arithmetic logic unit with a signal indicating that the picture frame is of a full size or a smaller size. Either of two-system processes each determining an imaging magnification is selected according to the signal. Thereby, an imaging magnification consistent with a picture size is specified automatically.

  • Patent number: 5376983
    Abstract: When moving frames are incorporated in a fixed frame and a cam ring, the lens barrel according to this invention is ready for fitting cam followers of the moving frames in the fixed frame or a plurality of moving cain grooves disposed on the cam ring irrespective of the number of moving frames to be incorporated, thus inserting the cam followers in the moving cam grooves by way of a single assembling cam groove. Accordingly, an assembling work of the moving frames in the fixed frame and the cam ring will be greatly facilitated and in an arrangement for which the moving cam grooves are provided on the cam ring, since the cam grooves may be bottomed cam grooves, a high rigidity cam ring will be realized. The lens barrel is further provided with a barrier closing assembly for selectively covering and uncovering an object end of the lens barrel.

  • Patent number: 5355109
    Abstract: A noise absorber that can be securely attached around electric wires of various diameters and types, and can be firmly closed without any electric wire caught between the ferrite parts. Wire supports are erected at both sides of a wire-receiving through hole on the inner surfaces of opposed walls of a first case member of the noise absorber. The tips of the wire supports are tilted toward the central axis of the through hole. Almost Y-shaped receptors are formed on the inner surfaces of opposed walls of the second case member for engaging with the tips of the wire supports when the case members are closed. The upper portions of the receptors serve as guide slopes for pressing inwardly the tips of the wire supports, so that the wires are securely pinched between the wire supports.

  • Patent number: 5264814
    Abstract: An electrical noise absorber comprising a magnetic body like ferrite attached around a flat cable and a fixing member. The fixing member comprises an inserting portion having a through hole for passing the magnetic body therethrough. Opposite walls defining the through hole extend in the direction, in which the magnetic body is inserted, to form a pair of cable fixing arms. Each of the cable fixing arms has a slot and projections for engaging the side edges of the flat cable. Engaging portions for engaging the periphery of the magnetic body inserted into the fixing members are provided on the top and bottom of the inserting portion. The flat cable and the magnetic body can thus be held immobile by the fixing members of the electrical noise absorber.

  • Patent number: 5116187
    Abstract: The present invention is concerned with an automatic speed changing apparatus preferably employable for a wheel loader. The subject of the present invention is to assure that no shift-down is carried out even when braking is effected and thereby a vehicle speed is reduced when the wheel loader approaches a dump truck (operation IV) during running of the wheel loader, e.g., along V-shaped tracks as shown in FIG. 4, whereby an operation can smoothly be performed without an occurrence of falling-down of load placed on the wheel loader while preventing an operator from feeling unpleasant. To accomplish the foregoing subject, the apparatus of the present invention is constructed such that determination as to whether or not the wheel loader is approaching the dump truck (operation IV) is made based on the determination as to whether or not lift arms (1a) are raised up to perform a loading operation, and if it is found that the foregoing determination is correct, the current speed stage is maintained.
