IPC: G11B7/123
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To unneccesitate a push-pull offset correction circuit on the side of the optical system that uses short wavelength light by cancelling the offset of a push-pull signal obtained in such optical system by means of the optical system that uses long wavelength light. SOLUTION: The offset component, which is contained in the push-pull signal PP detected by a DVD optical integrated device 5, is cancelled by a signal, which is a push-pull signal PP detected by a CD optical integrated device 6 and which is a signal (i.e., signal of offset component only) underforming the correction of the offset component. The push-pull signal PP in which the offset component is cancelled is used as a tracking error signal. As a result, it is possible to cancel the offset component contained in the push-pull signal PP without providing a push-pull offset correction circuit on the side of the DVD optical integrated device 5.

Abstract: PURPOSE:To form a large display image on a display plate without increasing the width size of a device, by constituting a reflection plate with a curved surface mirror which is curved so that right and left both end portions in comparison with the center portion may come nearer to a display source side. CONSTITUTION:Light projected from a display source 7 is projected on a reflection plate 13 passing through light shielding filters 11, 12, and its reflected light is projected on the display plate 6 of a display panel portion 5, and a display image is projected. A reflection plate 13 is constituted with a curved surface mirror which is curved so that right and left both end portions in comparison with the center portion may come nearer to a display source side 7. Accordingly, the display image reflected on the reflection plate 13 is curved in opposition with the curvature of the reflection plate 13, and becomes a three dimensional virtual image whose image formation position continuously changes so that the right and left both end portions may be located on this side. The width size of its display image projected on the display plate 6 becomes larger than that of a display image formed at the display source 7.

IPC: B41J2/21
Filed: 1994-02-03
Abstract: PURPOSE:To prevent waste consumption of ink and ejection failure thereof by a method wherein the numbers of times of the preliminary ejection for recovering a clogging are varied in accordance with kinds of inks. CONSTITUTION:After an ink jet head is preliminary heated by an electric signal by which ink is not ejected up to a specific temperature by which the ejection may be stable (S2), the ink is preliminary ejected in accordance with an electric signal of which frequency is lower than that in the recording so that the ejection failure of the ink after a long interval of non-recording is prevented. At that time, in the case where, for example, a plurality of colors of inks such as black, cyan, magenta and yellow are used in the color printing, the numbers of times of preliminary ejection are different with each other by setting them corresponding to the colors, that is, a record head of black ink corresponds to Nk times (S4), cyan to Nc times (S6), magenta to Nm times (S8) and yellow to Ny times (S10). Thus, the numbers of times of preliminary ejection correspond to the respective colors so that it is possible to recover the clogging without operating unnecessary number of times of the preliminary ejection in the case of the inks of cyan, magenta and yellow each having non-drying property.

Abstract: PROBLEM TO BE SOLVED: To make a precision equipment settable without any damage by equipping a shock relaxation member of a shape structure coming into close contact with the substrate surface of the precision equipment while being separated from a fixing member due to a deformation. SOLUTION: A spring 12 for relaxing shock is attached and fixed to a fixing member 11 of the precision equipment 1 with a spring fixing screw 13 and is carried to the upper portion of a through hole 16 of a substrate 2. Then, the equipment 1 is lowered and is placed on the substrate 2 while shock is being relaxed by the spring 12. In this case, the equipment 1 is moved along the surface of the substrate 2 and is positioned opposed to a bolt hole 21 of the substrate 2.

Also, a bolt 15 is screwed into the bolt hole 21, and the fixing member 11 and the substrate 2 are strongly fixed. In this case, the spring 12 that is composed in sectional crank shape is driven and deformed outward in the horizontal direction and is collapsed.
