Title: Detecting method for center position of optical disc
Inventor: ITO YUJI
IPC: G11B7/26
Filed: 1985-12-02
Abstract: PURPOSE:To promptly detect the center position simplifying a device, by integrally moving two sensors in a direction of passing through a concentric circular groove and detecting each position from a start point of the sensor, when it passes through the groove, so as to obtain the rotary center of the groove on the basis of said position of the sensor and an already known groove radius. CONSTITUTION:Since a moving distance a' from a home position is known by detecting a position of an optical pickup 6 as a sensor, when it passes through a groove 4, in a point A, a device reads coordinates of the point A for a virtual original point P to be A (O, a) because the home position of the optical pickup 6 for the virtual original point P is already known. While a moving distance b' from a home position is known by detecting in a point B a position of an optical pickup 8 when it passes through the groove 4, and the device reads coordinates of the point B for the virtual original point P to be B (L1, b) because the home position of the optical pickup 8 for the virtual original point P is known. Next a center position Q is obtained because a radius of the groove 4 is known. In this way, the device, using the two optical pickup, enables the two points of the innermost or outermost peripheral groove to be detected, promoting the promptness of detection.

Title: Three-dimensional display device
Inventor: SONEHARA TOMIO
IPC: G03B21/60
Filed: 1991-10-18
Abstract: PURPOSE:To obtain a three-dimensional color moving image which is reduced in the number of picture elements. CONSTITUTION:The three-dimensional display device consists of plural display devices 101 for parallax image projection, projection lenses 102 corresponding to the display devices 101, a lens plate 103, a retroreflective screen 105 which is placed on the rear focus plane of the lens plate 103, and a conversion optical system. The display devices 101 for projection are used for multiple projection to obtain the effect which reduces the burden of the number of picture elements on each device. Further, a parallax image is automatically positioned on the screen 105, so a projection display image is only projected on the lens plate 103 and no absolute position precision is required. Further, plural pieces of display information are put together and recognized, so picture elements in a matrix shape are inconspicuous and a feeling of quality is superior. For a display signal, a parallax image which is required before need not be generated by spatial sampling and composition. A continuous three-dimensional visual field is secured and even projection display devices which are wide in interval can be employed.

Abstract: PURPOSE:To simplify the structure and to decrease the cost, by making the fluctuation of the pressure, which is yielded in the vicinities of both side surfaces of a Karman vortex yielding body to act on a mechanical vibrating body, whose resonant frequency is changed in correspondence with the density of fluid. CONSTITUTION:When a detector is arranged in a pipe 1, fluid 2 enters into a first cavity 14 through introducing ports 5a and 5b and a through hole 11c and into a cavity 15 through an opening 43 and a through hole 16. Under this state, a vibrating plate 10 is vibrated by self-excitement. The vibrating plate 10 is vibrated at the resonant frequency of a vibrating system 40 comprising the first cavity 14, the part of the through hole 11c, the inside of a tube body 12 and the vibrating plate 10. When the fluid flows in the pipe 1, pressure change in Karman vortex is yielded in the vicinities of the both side surfaces of the vortex yielding body. The resonant frequency undergoes modulation in synchronization with the change. Therefore, the volume flow rate of the fluid flowing in the pipe 1 can be detected based on the modulation frequency due to the vortex in a pulse train signal 24a.
