Title: Ring laser gyro device
Inventor: NAKAMURA SHIGERU
IPC: G01C19/68
Filed: 1990-10-18
Abstract: PURPOSE:To scarcely generate a lock-in phenomenon and to reduce in size an entire device by composing a substantially circular optical waveguide of a light emitting element and an optical resonator, cutting out part of the waveguide, and inserting a Faraday element. CONSTITUTION:An optical resonator of an output light of a light emitting element 19 is composed of a substantially circular optical waveguide 14 provided on a gyro board 12, and a light turning in one direction and a light turning in the other direction exist in mixture in the resonator. A beat signal is obtained through a directional coupler 16, a Y-type branched coupler 17 and a photodetector 18A, and the rotating angular speed of the resonator can be detected by the frequency of the signal. Part of the waveguide 14 is partly cut out, and a Faraday element 20 is inserted to provide a desired phase difference between the light turning in one direction and the light turning in the other direction in the resonator. Since an optical fiber is not used, a large scale lock-in phenomenon caused by the internal scattering of the fiber does not occur, and the waveguide is reduced in size, and hence the entire device can be reduced in size.

IPC: G03F1/64
Filed: 1989-10-27
Abstract: PURPOSE:To maintain the flatness of the surface of a pellicle and to enhance the accuracy of detection of foreign matter at the time of inspection by piercing an opening in at least a part of a pellicle frame for fitting the pellicle to a photomask and by making the opening closable with a tape. CONSTITUTION:A pellicle 12 is a transparent thin film of nitrocellulose and is fixed through a pellicle frame 13 of an Al alloy, etc., so that a reticle (photomask) 11 is covered with the pellicle 12 at a certain interval to protect a pattern part on the reticle 11. An opening 14 of a small diameter is pierced in one side of the frame 13 and a tape 15 having superior dust-tightness is stuck so as to close the opening 14. A part 16 of the tape 15 is not stuck to facilitate stripping. Since air permeability is rendered to an airtight chamber formed by the pellicle 12, the pellicle frame 13 and the reticle 11, the deformation of the surface of the pellicle 12 due to the difference between the internal and external pressures of the airtight chamber is prevented. The flatness of the surface of the pellicle is maintained and the accuracy of detection of foreign matter at the time of inspection is enhanced.

Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/043
Filed: 1985-12-13
Abstract: PURPOSE:To inhibit the image of a secret original from being formed by provid ing a means which irradiates the original with light and detect the identification symbol of the secret part of the original and also providing a control means which stops image forming operation at the time of detecting the identification symbol. CONSTITUTION:The original G is placed on an original platen 2 and irradiated with light from a lamp and its reflected light is focused on a photosensitive body to form an image. A spot light source and a detector are provided by the lamp. The original G is provided with identification symbols, e.g. blue symbols S1 and S2 for a part to be kept secret. Then, light is irradiated from the spot light source and the detector detects the positions of the identification symbols S1 and S2. Then, signals of the positions specified by the identification symbols S1 and S2 are sent to a control circuit and an erasure array is put closely to the corresponding positions on the photosensitive body to erase the image of the hatched part shown by S1 and S2. Thus, the secret original is identified automatically to inhibit its image from being formed.

Title: Sound proof grommet and insertion of the same
Inventor: KONDO MASAYUKI
IPC: H02G3/22
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To shield the sound at a cavity portion of a grommet hole portion, by providing the structure that a sound shielding plate is fixed in the side of a large aperture and a sound shielding layer is exposed in the external side of the grommet body. SOLUTION: A sound-shielding body 41 is loaded in such a manner that a sound shielding plate is fixed at the engaging portion at the internal side of a large aperture 33 and a sound shielding layer 47 is exposed at the external side of a grommet body 37. Thereby, the sound shielding layer 47 does not change even when the grommet body 37 is fitted to a body panel 23. As a result, unexpected force causing disengagement of the sound shielding plate 41 due to deformation of the sound shielding layer 47 is never generated and therefore a gap causing leak of sound is never formed at the cavity generated by cutting out the sound shielding member 27 to fit the sound proof grommet 21, thereby the sound can be shielded.

IPC: B41N3/00
Filed: 1990-10-19
Abstract: PURPOSE:To shut off air and ultraviolet ray, stablize the quality of a resin layer during storage and prevent dust attachment and damage during transport and storage by covering a resin plate cylinder before or after exposure with thermally contractable plastic film. CONSTITUTION:A resin plate cylinder 1 is a gravure cylinder, and photosensitive resin 2 is polyamide, polyester acrylic or urethane acrylic resin, and thermally contractable plastics are polyolefin, polystyrene, polyvinyl chloride and fluorine resin film 3. In addition, these resins contract at temperatures below 150 deg.C and uniformly stick to a photosensitive resin layer 2 of cylindrical shape 1 with a coated external surface. Thus a resin plate cylinder is preserved with the coating of the resins. For example, a photosensitive coating liquid of polyamide resin is uniformly applied to the surface of a gravure cylinder and a thermally contractable film is applied to the coated applied surface and the cell formed on the applied surface.

IPC: B29C33/38
Filed: 1987-11-09
Abstract: PURPOSE:To make it possible to easily judge whether a filling pattern is proper or not by a method wherein intersecting points of the bisector of an angle between a normal line drawn from an arbitrarily selected set point on an isochronous line to said isochronous line and a normal line drawn from said point to an adjacent isochronous line and said adjacent isochronous line are obtained successively. CONSTITUTION:A normal line lnb (for example, n=2, or l2b) is drawn from an arbitrary point An (or A2) on an arbitrary isochronous line tn (or t2) to the isochronous line tn (or t2) so as to intersect an adjacent isochronous isochronous line tn+1 (or t3) at the point Bn+1 (or B3). Further, a normal line lnc (or l2c) is drawn from the point An (or A2) to the adjacent isochronous line tn+1 (or t3) so as to intersect the adjacent isochronous line tn+1 (or t3) at the point Cn+1 (or C3). Here, a point An+1 (or A3) is obtained as the intersecting point of the bisector ln (or l2) or acute angleBn+1AnCn+1 (or acute angleB3A2C3) and the adjacent isochronous line tn+1 (or t3). The resultant bisector ln (or l2) represents the course of the flow of molten resin between the isochronous lines tn (or t2) and tn+1 (or t3). As hereafter repeated by similar procedure, a continuous filling flow chart is described by connecting bisectors ln-l19 (or l2-l19) to one another. As a result, a course of element regions, which are represented by hatching, can be displayed.

Therefore, the pseudo generating operations of the plural terminals can be controlled and the operating states of the circuits can be confirmed by monitoring the information of each circuit from a remote place. Thus, the states of the lines can be managed collectively.
