Title: Treatment method for radioactive liquid waste
Inventor: YASUMURA KEIJIRO
IPC: G21F9/12
Filed: 1989-09-22
Abstract: PURPOSE:To enable effective removal of soluble and insoluble substances from a radioactive liquid waste of low radioactivity concentration by feeding radioactive liquid waste through a vessel in which larger particle sized activated carbon is filled at upper layers and smaller sized one is filled at lower layers. CONSTITUTION:A vessel 3 is filled by activated carbon in an order that particle sizes is larger in an upper layer 4a and smaller in a lower layer 4b, and radioactive liquid waste passes through the vessel. As the activated carbon is filled by that method, insoluble substance in the waste water such as a short thread is removed by the upper layer and soluble substances such as a detergent is removed by a highly adsorptive activated carbon in the lower layer. Accordingly, both soluble and insoluble substances can be removed without any clogging and therefore the radioactive liquid waste containing those substances can be very conveniently treated.

Title: Governor drive controller
Inventor: IKEDA TAKAYUKI
IPC: F02D1/08
Filed: 1990-09-14
Abstract: PURPOSE:To prevent any overload from being applied to a motor so as to prolong a lifetime of the motor by stopping the motor as soon as pressing force of a fuel control lever against a stopper exceeds a predetermined value. CONSTITUTION:When a fuel control lever 2 abuts against a stopper 3 or 4, a motor 8 is stopped as soon as pressing force against the stopper 3 or 4 reaches a predetermined value. Accordingly, the fuel control lever 2 always abuts against the stopper 3 or 4 at optimum force even if incorrect positioning of the stoppers 3, 4 occurs at the time of manufacturing. Therefore, it is possible to prevent the motor 8 from being overheated, thus prolonging a lifetime of the motor 8.

Abstract: PURPOSE:To make it possible to simply read out and check a content by a one-touch operation, by defining and storing a desired measurement, together with the title name thereof, in a specified key. CONSTITUTION:A title name is key-inputted from a title input key 4, and a measuring condition thereof is key-inputted from a measuring condition input key 2. These input data are stored temporarily by a control element 9. When a ten-key 3 is operated, subsequently, the control element 9 stores the title and the measuring condition in a function memory 11 so that they correspond to each other. Moreover, an address of the memory 11 is specified by the ten- key 10 and then a function key 8 desired to be designed in correspondence subsequently is operated. By these operations the control element 9 stores paired data in the memory 11. At the time of recall, the control element 9 makes a display element 13 display a corresponding title in a position corresponding to the key 8. When a desired key is set during this display, the control element 9 calls a measuring condition corresponding thereto out of the memory 11 and sets a measuring element 12 and the display element 13 to be controllable according to the condition.

The rectangle of the extracted character line and the area 3 are divided into necessary number of parts. Then each dividing area and extracting row rectangular are area-compared and a part judged to be a row rectangle which is largest in the occupying rate of the extracted row rectangular in each divided area is set to be an effective row judging site in a divided area. By distinguishing the matrix like this, they are cut into groups with attribute to some degree.

Title: Ink jet recording method and device, color filter, display device, device equipped with the display device, ink jet head unit regulating device and method, and ink jet head unit
Inventor: AKAHIRA MAKOTO
IPC: B41J2/05
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To enable image data to be recorded with high image grade and almost without density irregularities by providing a means for detecting the relative positional deviation of plural ink jet heads and a means for detecting an angle of inclination with a scan direction of the ink jet heads. SOLUTION: Each of the nozzle on each of ink jet heads is caused to discharge an ink while moving a head unit for scan relatively with a glass substrate in the X direction to insert an image of line pattern about 50mm long. In addition, a heat pulse of the same pattern is applied to all the heaters of the nozzles and a bit correction is made at an intermediate point (S12). Next, a line sensor camera measures the density of each of the serted images of line pattern while moving for scan relatively with the glass substrate in the Y direction (S13). Further, the ink discharge from each of the nozzles is determined based on the sought density of each of the line patterns (S14).  Thus it is possible to obtain data on the irregularities of the ink discharge of each of the nozzles and prevent a color unevenness in a color filter from being generated and avoid the trouble of regulating the relative positions among three ink jet heads.
