Filed: 1990-07-04
Abstract: PURPOSE:To miniaturize a tap changer, and to reduce the quantity of heat dissipation by bringing one tap to an OFF state when load currents reach a zero point by utilizing the OFF state of a thyristor and bringing other taps to an ON state. CONSTITUTION:The 'ON' and 'OFF' states of first and second TRIACs 11, 13 are changed in response to the state of the changeover of a TRIAC changeover switch 23 in a tap changer 1, thus tap-changing the A-tap 9a and B-tap 9b of a transformer 7.

Title: Optical filter for display
Inventor: YAMAZAKI FUMIHARU
IPC: H01J11/44
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a filter and occurrence of abnormality caused by the deterioration due to heat generation of a screen during lighting for long time by installing a filter having a heat resistance value within a specified region on a display screen. SOLUTION: Thermal resistance (m2.K/W) of an optical filter 10 provided on a display screen 21 of a plasma display panel 20 is set in the range of 0.005 to 0.1. The optical filter 10 is obtained by forming transparent high polymer such as acryl or polycarbonate, where near infrared ray absorbing pigment is mixed like a plate or reflecting near-infrared rays on the screen side of the transparent plate-like formed body to be intercepted, thereby forming a silver thin film effective for electromagnetic wave interception. Both methods may be used concurrently. A silver thin film may be formed on a transparent high polymer film as need, and then stuck to a plate-like formed body by a pressure-sensitive adhesive material. The sheet resistance value of the silver thin film is 10 Θ/square or less, and the transmissivity for near-infrared rays or visible light rays is controlled by regulating the quantity of near-infrared ray absorbing pigment mixed and the thickness of the silver thin film.

Title: Cornea protecting agent and production thereof
Inventor: SERUGEI NIKORAEBICHI BAGUROFU
IPC: C08L1/00
Filed: 1990-07-09
Abstract: PURPOSE: To obtain a cornea-protective agent consisting of a mixture composed of tylose solution with the size of the maximum microsphere within a specific range, aqueous sodium chloride solution and buffer solution with a specific pH range, capable of mitigating the extent of cornea damage and complication in cornea operation and rapidly excludable through natural route. CONSTITUTION: This cornea-protective agent is obtained by the following process: a 0.7-0.8% solution of tylose as a cellulose derivative is prepared, being mixed with an aqueous 0.85% sodium chloride solution and a buffer solution with pH7.2-7.4, the resultant solution is subjected to centrifugal separation followed by separating the resultant supernatant, which is then filtered to obtain a tylose fraction as the objective cornea-protective agent with the size of the maximum microsphere of 0.4μm. Being low in tylose concentration, this cornea- protective agent can be promoted in exclusion from the eye within an appropriate period after operation; furthermore, because the size of the microspheres is smaller than the physiological pore size, this agent can also be promoted in exclusion through natural route.

Title: Picture retrieving device
Inventor: MORIYAMA HIROFUMI
IPC: H04N5/76
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To make accelerable the speed of the rotating retrieval of a picture by obtaining a rotating angle maximum in the normalizing correlation value between a rotation template picture and an inputted picture, and outputting the rotating angle and positional information in the video of the inputted picture. SOLUTION: The angular interval of the rotating angle of a rotation template picture is made to be 45 deg. e.g. to obtain a normalizing correlation value at each rotating angle. Since the normalizing correlation value is maximized at a rotating angle where an inputted picture matches with a rotation template picture, the rotating angle close to the maximum value is searched by roughly varying the rotating angle. When the maximum normalizing correlation value becomes equal to or larger than a threshold value, a normalizing correlation value at a rotating angle obtained by adding a step angle, such as 1 deg., to the rotating angle is obtained. When the rotating angle moves away from a coinciding angle by the fine increase of the rotating angle, whether it becomes closer by fine reduction is investigated.  At the time of becoming smaller than the maximum normalizing correlation value by a little larger or smaller rotating angle, the maximum normalizing correlation value is extremely close to a peak value and the rotating angle is close to the coinciding angle, thereby the coincidence of both of the pictures is detected.
