Title: Display device
Inventor: TANAKA TOSHIHIKO
IPC: G09G3/36
Filed: 1994-09-01
Abstract: PURPOSE: To make it possible to execute gray level conversion when steps of gray levels are conspicuous to observer, to execute a high-speed processing when these gradations are inconspicuous and to prevent the disturbance in images by switching of the processing in switching of the gray level conversion. CONSTITUTION: This display device is provided with a control means 5 for switching the processing of a gradation processing means 2 to a gray level conversion and gray level non-conversion and selects either thereof by detecting the change-component of image signal in the case the incoming image signals with gradations are displayed on a liquid crystal display device 4. The gray level conversion of the gradation processing means 2 is preferably the gray level conversion based on an erroneous dispersion. The liquid crystal display device 4 is also applicable to the case of making calculation by orthogonal functions. The switching of the gray level conversion and the gray level non- conversion is executed in synchronization with the frames of the image signals.  The device is more preferably provided with an adjusting means 6 for adjusting the timing for supplying the image signals to a driving means 3 at the time the gradation processing means 2 executes the gray level conversion and at the time the means executes the gray level non-conversion.

Title: Controlling method for exciting current of magnetic bearing in vertical shaft electric machine
Inventor: MIYAJIMA TAKEO
IPC: F16C32/04
Filed: 1981-12-23
Abstract: PURPOSE:To bear a load which is always constant and relatively light at a thrust bearing by controlling the exciting current of the magnetic bearing through a control signal which is obtained due to the variation in the thrust load. CONSTITUTION:When a water thrust force is transiently increased due to the variation in the load of a water wheel, the rotary unit of an entire electric machine which includes the water wheel is depressed, and the pressure of an oil film 11 between the thrust runner 1 and the thrust pad 2 increases. The quantity of varied pressure of the film 12 is detected by a hole 12, and is fed through a transmission line 13 to a converter 7, in which the pressure signal is converted into an electric signal. This electric signal is, in turn, fed to a controller 8, thereby controlling the current supplied to the exciting coil 10 of the magnetic bearing 5 from a power source 9 so as to increase the attracting force of the bearing 5 and to absorb the increased component of the thrust load. Accordingly, the load of the thrust bearing is maintained at the prescribed value.

Title: Troubled point identifying system for multiple optical transmission equipment
Inventor: TANIGUCHI KAZUHIKO
IPC: H04B17/00
Filed: 1988-08-24
Abstract: PURPOSE:To attain the identification of a troubled place by deciding that the equipment is troubled when a trouble is continied even after the signal of the output of a transmitting part is folded back to a receiving part directly and deciding that the transmission line is troubled when the trouble is stopped after the signal is folded back. CONSTITUTION:When the trouble is shutoff of a receiving signal an RIN DET (receiving signal shutoff detecting circuit) 34 outputs the alarm (RIN ALM) of the receiving signal shut-off and adds if to a control device (CONT) 36. When the trouble is SYNC (pull out) or ERR (bit error), an alarm (SYNC ALM) of the SYNC of the output of an SYNC ERR DET (trouble detecting part) 35 or the alarm (ERR ALM) of an ERR are added to the CONT 36. A relay driving circuit 37 is operated by the control signal of the CONT 36 and a contact 38 of a relay is switched to a transmitting side. As this result, when the trouble is continued even after the signal at the transmitting side is folded back to a receiving side directly, an LED(light emitting diode) 40 to show the equipment trouble lights up or when the trouble is stopped after the signal is folded back, an LED 39 to show the transmission line trouble lights up. Thus, without a manual maintenance work, the trouble and the optical transmission line trouble can be identified.

Abstract: PURPOSE:To improve easiness to use and a feeling of satisfaction and to emphasize a healthy point by displaying large only a specific digit of numerical values of the weight of one's body displayed and making the display easy to see while being provided with a secret function. CONSTITUTION:When a change of the weight of one's body is considered, it is hardly considered that the weight of one's body is changed suddenly as much as 10kg and the change of a unit of 10-100g is influenced by a measuring condition. Accordingly, in case of the display of kg, a figure 8 of one digit is displayed large with the significant change of 500g-1kg as reference. Then, the figures 9 and 10 of the digit which are not emphasized are diminished in size to an extent that these figures are understood when seen well. In this way, the numerical values of the weight of one's body are made to then display which is easily seen while being provided with the secret function that the numerical values are not desired to be seen by others and besides, the increase of a space and the cost can be controlled to a minimum by exlarging the display.

Title: Address map input method having automatic subdivision processing
Inventor: FUJIWARA HIROAKI
IPC: G09B29/00
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To improve efficiency in the correction of data and to secure the accuracy stability of data. SOLUTION: After electronic data are read onto an address map input system, a paper drawing plotting update conditions is read onto this system as image data. Next, the coordinate systems of vector data and image data are matched, the apexes of a pen polygon for subdivision are made correspondent between both the electronic data and image data like the apex of image data corresponding to an apex A of electronic data as (a) and the apex similarly corresponding to an apex B as (b), these apexes are respectively instructed one by one on the surface of a tube, and the image data are extended/compressed so that the vector data and image data can be overlapped. After image data MD, which are not overlapped with the vector data even after extension/compression, are automatically extracted, these image data MD are converted into vector data VD by raster/vector converting processing.  When subdivision processing is performed later, the electronic data are updated.
