Filed: 1985-01-11
Abstract: PURPOSE:To reduce an occupied space and to attain three-dimensional display by displaying at least a display scale and display numerals indicating the position of an indicator under the state positioned in the space. CONSTITUTION:In a panel-like hologram 1 consisting of glass, and object image indicating the speed display scales and speed display numerals is exposed to the surface of the glass on the basis of a holography technique. An indicator 2 linearly reciprocated in proportional to the speed is made of an electrooptical indicator having a glass-sealed structure e.g. During the traveling of a car, a regenerative lighting source 3 lights up to project light always to the hologram 1.

IPC: G01B11/00
Filed: 1982-01-12
Abstract: PURPOSE:To make the device compact, light weight, and highly accurate, by adding a current for shifting the target by the diameter of an aperture to the correction data of the target at the time of the light servo, thereby shifting the target. CONSTITUTION:A time division switch 3 is normally switched at three kinds of timings based on the relationship between the outputs of a horizontal axis coil and a vertical axis coil and a quantity of light. At the time of the light servo for detecting the quantity of the light, a shift voltage +alpha corresponding to the aperture diameter is added to the horizontal axis output and the vertical axis output, and the target is deviated from the aperture. When the deflecting current, to which the shift voltage +alpha is added, is applied to the horizontal axis coil H and the vertical axis coil V, the target is completely deviated from the aperture. The quantity of the light at this time is received by a photomultiplier. Said signal is appropriately processed, a high voltage circuit 16 is controlled, and the high voltage is varied by the increment of the variation in the quantity of the light. As a result, the fluctuation of the output data is prevented regardless of the quantity of the incident light.

Abstract: PURPOSE:To lessen the peak of the power consumption and also to reduce occurrence of the noise in order to obtain a low-cost constitution of the refresh system, by dividing the volatile semiconductor memory element into more than one unit of minor groups and shifting the refresh time with every minor group of the element. CONSTITUTION:Delay circuit 5 and 5' are added newly.

After delay 5' of td2, the groups of dynamic RAM4'' belonging to driving circuit 3'' start the refresh action. Accordingly, the refresh actions end with a shift with every group, and thus the piling of the impulse power consumption can be avoided for every group. Thus, the current value is obtained for waveform (7) which is gentle as a whole.
