Title: Measuring instrument and display method therefor
Inventor: MACHIDA NORIHISA
IPC: A61B5/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To reliably confirm the last time measured value to satisfy the prescribed last time measured value condition regardless of the existence of the occurrence of erroneous measurement by deciding a normal measured value range as the last time measured value condition. SOLUTION: The last time measured value can be confirmed by displaying the last time measured value based on the last time measured value display information being held up to this time measurement. The prescribed last time measured value condition is arranged, and when this time measured value satisfies the prescribed last time measured value condition, this time measured value display information for a display can be displayed as the last time measured value in the next time measurement by holding the information as display information up to the next time measurement. When this time measured value does not satisfy the prescribed last time measured value condition, a measured value before the last time when viewed from the next time can be displayed as the last time measured value in the next time measurement by maintaining the last time measured value display information.  Therefore, when a normal measured value range is decided as the last time measured value condition, even if erroneous measurement is caused in this time measurement, the normally measured final measured value can be displayed as the last time measured value in the next time measurement, and while, when this time measurement is normal, the measured value can be displayed as the last time measured value in the next time measurement. Therefore, the last time measured value to satisfy the prescribed last time measured value condition can be reliably confirmed regardless of the existence of the occurrence of erroneous measurement.

Filed: 1985-04-22
Abstract: PURPOSE:To save power consumption with a reduction in the number of terminals by inputting two kinds of signals different in the voltage value from a common input terminal to set two kinds of modes. CONSTITUTION:An integrated circuit is composed of a terminal Common concurrently serving for normal input logical computation and the generation of test mode, a normal input logic terminal I2, normal input logic getes 11 and 12, a test mode generation circuit 13 and NOR gates 15 and 16. When a signal within the logic amplitude range of 0 - power source voltage (+VCC) is applied to the terminal Common, the output of the test mode generation circuit 13 moves to '0' level, at which terminals T1 and T2 of the NOR gates 15 and 16 transmit the normal input logic. Then, when a signal exceeding the power source voltage (+VCC) is applied, the output of the test mode generation circuit 13 exceeds the input logic threshold of the NOR gates 15 and 16 to enter the test mode. This enables switching between the normal input logical computation and the generation of test mode with one common terminal Common.

Abstract: PROBLEM TO BE SOLVED: To allow a pixel electrode to be positively brought into contact with a drain electrode via the contact hole of an interlayer insulation which is made of transparent resin by treating the surface of a substrate containing the surface of the drain electrode of a lower part exposed to the contact hole for cleaning the surface of a contact part. SOLUTION: A TFT is formed, and a photosensitive acryl-family transparent resin is used for forming an insulating film 10 to eliminate a step part for planarization of a surface. Then, a contact hole 11 is formed so that one part of the surface of a drain electrode is exposed through exposure and development treatment. At this time, a foreign object that is in a granular shape or in a uniform thin film state remains as a residue on the surface of the opening part of the contact hole 11. In this case, for almost all the residues, an interlayer insulation 10 is used as a main constituent. After that, the entire surface including the contact hole 11 is removed of the residues by surface treating, thus a pixel electrode 13 is formed.
