Title: Hologram duplicating method
Inventor: ONO MOTOJI
IPC: G03H1/20
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To easily duplicate a desired optical characteristic hologram with high mass productivity regardless of the forming condition of the hologram by specifying the difference between the peak wavelength of the diffraction efficiency wavelength dependency curve of diffracted light in each in-plane point of a duplicating original hologram and the wavelength of the light used in duplication. SOLUTION: This method is formed of an original hologram 1, a cover glass 2, a hologram sensitive material 3, a divergent light 4, and a black absorber 5. The divergent point position of the light used for duplication of hologram is arranged so as to be different from both two divergent point positions of the light used for the formation of a duplicating original hologram. When white light is emitted from the divergent point position of the light used in duplication toward the duplicating original hologram, the difference between the peak wavelength of the diffraction efficiency wavelength dependency curve of diffracted light in each in-plane point of the duplicating original hologram and the wavelength of the light used in duplication is set so as to be half or less of the peak full width at half maximum of the diffraction efficiency wavelength dependency curve in each point.

IPC: B41J2/175
Filed: 1987-09-30
Abstract: PURPOSE:To prevent the unnecessary rejection of droplets after dot recording and thereby perform high-quality recording by providing a constitution in which a cylindrical piezoelectric vibrator and the entire periphery of a liquid passage are covered with an elastic member. CONSTITUTION:A liquid jet recording head has a cylindrical piezoelectric vibrator 1 fixed to a subtank 6 and the entire liquid passage 2 which are integrally covered with an elastic member 9. This elastic member 9 is, for instance, made of a high-polymer elastic material, covering the whole part of the cylindrical piezoelectric vibrator 1 and the liquid passage 2. The elastic member 9 absorbs the unnecessary residual vibration of the cylindrical piezoelectric vibrator 1 and the liquid passage 1. Subsequently, the inner pressure fluctuation of the liquid passage 2 due to vibration is prevented, so that the ejection of liquid droplets which is not related to printing after the liquid droplets are ejected for printing does not occur. In addition, the distortion stress of the subtank is absorbed. As a result, no stress is inflicted to the cylindrical piezoelectric vibrator the liquid passage 2 and therefore, damage on the cylindrical piezoelectric vibrator 1 or the liquid passage 2 can be prevented.

Abstract: PURPOSE:To prevent a cleaning blade, a photosensitive drum, and a driving system from damaging by detecting the movement of the blade from the surface of a photosensitive body against the energizing force of an energizing means, and stopping driving the photosensitive body and reversing it by a specific angle successively. CONSTITUTION:When frictional force increases abnormally between the photosensitive drum P and cleaning blade 1, the contact of the blade 1 for the photosensitive drum P moves to a position T1 at the rotation-directional downstream and the blade 1 itself deforms, so that a holder 2 moves away from the photosensitive drum P as a reaction. Then, a support means 5 which supports the holder 2 with a screw 4 is guided to a bearing 7 against the press-contacting force of a spring 9 to move in the same direction, thereby turning on a microswitch SW with a pressure part 8. Then, a CPU100 outputs a driving stop signal to a driver circuit 101 to stop a driving motor M and also stop the rotation of the photosensitive drum P. Further, a reverse driving signal is outputted for a certain time and the driving motor M is driven reversely to reverse the photosensitive drum P by the certain angle.

Abstract: PURPOSE:To miniaturize a transistor as a memory-cell by forming a collector region, a base region and an emitter region through a self-alignment system. CONSTITUTION:A collector leading-out layer 6 and an inter-layer insulating film 7 are formed onto an active region, an opening is shaped to the inter-layer insulating film 7 and the collector leading-out layer 6, and sidewall films 8 covering the sidewalls of the opening are formed.
