Title: Flat x ray imager with moisture-proof seal structure
Inventor: ROBAATO FUOORESUTO KUASUNITSUK
IPC: H01J31/50
Filed: 1992-08-28
Abstract: PURPOSE: To provide a protective cover which minimizes loss and scattering of light from a scintillator. CONSTITUTION: A radiant ray imager 10 are composed of a scintillator 30 and a light detector arrangement 20 combined together. By arranging a surrounding ring 40 around an outer side wall of the scintillator, and bridging a surrounding ring cover 50, while jointing to the surrounding ring air-tightly, a chamber 55 to air-tightly surround the scintillator is formed. The surrounding ring cover is practically impermeable for water and transmittable for radiant ray, so that scattering of light from scintilator is minimized. By evacuating the compartment and absorbing the cover toward the light detect or arrangement, adhesion between the cover and scintillator and between the scintillator and the light detector arrangement is guaranteed. By putting desiccant 60 in the chamber, protection for water absorbing of the scintillator is enhanced.

Title: Focusing device for zoom lens
Inventor: MARUYAMA TAKAICHI
IPC: G03B13/36
Filed: 1986-09-29
Abstract: PURPOSE:To obtain a simple, precise focusing device by permitting a sampling pulse which changes in response to the position of a zoom ring to maintain an output from a charge/discharge circuit and controlling a drive part in a master lens part by said output. CONSTITUTION:The zoom ring 14 is turned to turn a cam mechanism, which advances and retreats a movable lens in a zoom lens part A. Since the cam mechanism scales the zoom ring 14 in response to the logarithm function of a focus distance in the zoom lens part A, the movable lens in the zoom lens part A advances and retreats by the logarithm function in response to the turn of the zoom ring 14. Together with the advance and retreat of the movable lens in the zoom lens part A, the position of the zoom ring 14 is detected, and a sampling pulse generator circuit 60 outputs a pulse corresponding to the position. The discharge of the charge/discharge circuit 70 in which a printing voltage varies with information about a distance to an object maintains the changing output, which drives the drive part 23. Then the movable lens in the master lens part B is drived to focus the distance. Thus the simple, inexpensive, precise focusing device can be obtained.

Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To disable ciphered data to be reproduced even when the data are copied and also to enable unciphered data to be reproduced. SOLUTION: When an (n)th sector is an area where physical format information are to be recorded and an (n+2)th sector is an area where copyright control information are to be recorded, the (n+2)th sector and an (n+5)th sector become unwrttable areas with an embosment work. Plural sectors are made unwritable so that the copyright control information can not be recovered by an error correction processing. Plural unwritable areas are formed at the interval of the prescribed number of sectors. In this disk, the copyright control information can not be obtained, but the physical information can be obtained. When recorded data are ciphered, since the copyright control information can not be reproduced, the ciphered data can not be decoded. On the other hand, unciphered data can be reproduced by using the physical format information.

Title: Sign mounting and demounting equipment
Inventor: HONMA MOTOAKI
IPC: H02G1/00
Filed: 1994-09-27
Abstract: PURPOSE: To set up a sign on an overhead cable easily from the ground without using a height working car by using an equipment which, having holding sections which open mounting sections when being pressed and a spring which usually holds the mounting sections in a closed condition, is temporarily installed in a temporary installation section with the holding sections being pressed. CONSTITUTION: A sign mounting tool 4 is installed in a temporary installation section 51 with holding sections 42 being pressed. Under this condition, the holding sections 42 are held by pins 54 and therefore the sign mounting tool 4 does not come off easily from an operation tool 5. At the same time, since the holding sections 42 are being pressed, mounting sections 41 are opened by the width which is the same or larger than a diameter of an overhead cable 1. A worker draws the sign mounting tool 4 near to the overhead cable 1 and then gets the overhead cable 1 caught on a recessed section 41B of the mounting sections 41. Under such a condition, the worker inclines an operation pole on which the operation tool 5 is mounted a little bit to the side where there are no pins 54.  As a result, the sign mounting tool 4 comes off from the temporary installation section 51 and a distance between the holding sections 42 is extended and the mounting sections 41 are closed and the sign mounting tool 4 is installed on the overhead cable 1.
