Title: Light adjusting sheet and liquid crystal display device provided with the sheet
Inventor: YOKOTA TOMOHIRO
IPC: G02B5/02
Filed: 1992-05-07
Abstract: PURPOSE:To improve luminance in the front direction by disposing numerous protrusions with the tip thereof rounded into protruding arc shape in cross section and numerous recessions with the root parts thereof rounded into recessed arc shape in cross section alternately and approximately parallel on one face of a sheet. CONSTITUTION:Numerous protrusi6ns 9 with the top parts 9a thereof rounded into protruding. arc shape in cross section, and numerous recessions 12 with the root parts 12a thereof rounded into recessed arc shape in cross section are disposed alternately and approximately parallel on the light outgoing face of a square sheet. It is desirable that one slant face of the protrusion 9 and recession 12 is curved or bent to some extent within a range of not lowering converging performance, and the approximately parallel state means that the respective top parts 9a of numerous protrusions 9 and the respective root parts 12 of numerous recessions 12 are approximately parallel. The back face of the sheet is formed into the fine irregular face by a mat-rolling method so as to be made into the optically unsmooth face. The luminance in the front direction is thereby improved, and the angle of visibility is enlarged, and that there is no fear of optical adherence to a light guide plate.

Title: Loop network intermittent fault recovery system
Inventor: KIMURA YUKIO
IPC: H04L12/42
Filed: 1989-05-08
Abstract: PURPOSE:To prevent the degradation in the communication quality when an intermittent bit error begins occurring by monitoring whether or not the rate of the number of an error transmission frame with respect to the transmission frame total number exceeds a prescribed value. CONSTITUTION:A reception relay frame number counting circuit 15 counts the number of received and relayed transmission frame and outputs a comparison instructing signal in a comparator 16 when it overflows. When an intermittent fault begins occurring, the bit error of the transmission frame takes place and a bit error is detected from the transmission frame received from an optical module 4 via a changeover switch 6 by a CRC detection circuit 8. When the result of comparison of the comparator 16 is equal to or more than the compared value, it is informed to a control circuit 13, the changeover switch 6 is switched to the position of the B system transmission line and the A system transmission fault is informed to the operator. Thus, the degradation in the communication quality is prevented.

IPC: G03F1/84
Filed: 1982-07-05
Abstract: PURPOSE:To prevent the deterioration of workability of a defect inspection by a method wherein a signal detected from a chip is recorded in a memory to be compared with a signal detected from another chip, and the difference signal thereof is determined as a defect. CONSTITUTION:When a mask 9 is transferred in the direction of a broken line arrow mask, a detector system is transferred in the direction of a solid line arrow mark, a lens 1 and a sensor 3 face with the chip A, and detection of a pattern is performed. At this time, no chip exists to face with a lens 2 and a sensor 4. Then, when an automatic change-over switch 12 is operated to connect the output terminal of an amplifier 7 to the memory 11, the detected signal of the chip A is stored in the memory 11. When the mask 9 is transferred by one pitch, the lens 2 and the sensor 4 face with the chip B, while no chip exists to face with the lens 1 and the sensor 3. Then, a change-over switch 13 is operated automatically, and when the input terminal of a comparator 10 is connected to the memory 11, the memory 11 reads out at any time the detected signal of the chip A following the detection to the chip B of the lens 2 and the sensor 4, and the read out signal is applied to the comparator 10. The comparator 10 compares the presently detected signal of the chip B with the detected signal of the chip A, and determines the difference signal thereof as the defect.

Abstract: PURPOSE:To minimize sheets of paper which are discharged into an overflow box by detecting a full capacity expected condition prior to the complete full capacity condition of a division box and preparing an empty translocating mechanism in the position of said full capacity expected division box in the optimum condition in a paper classifying device. CONSTITUTION:When a full capacity expected condition in any of division boxes with automatic take-out is detected by a full-capacity detecting device 3, an empty translocating mechanism 2 is prepared in the position of the full capacity expected box by means of a translocation control device 5.

Title: Method of treating muddy water
Inventor: KIKUCHI TOSHIYUKI
IPC: C02F1/00
Filed: 1977-09-26
Abstract: PURPOSE: To form condensation bodies for a short time, by adding high concn. sodium silicate solution and high concn. acidic solution.  
     CONSTITUTION: Extremely hard gelled bodies are obtained under a hydrous condition by injecting high concn. sodium silicate solution and high concn. acidic solution to muddy water and by curing after rapid agitation. If slow agitation, gelling becomes imperfect, and created gelled bodies flow out from the meshes of a filter cloth when the bodies are pressurization dehydrated. The Na +  ions of sodium silicate react with heavy metals in muddy water and stay in muddy water, and the surfaces of solids in muddy water are mixed with acidic solution after the surface are covered with sodium silicate solution, thus allowing the prevention of the re- rendering of heavy metals
