Title: Color display method for ph image
Inventor: TAKAMATSU SHUJI
IPC: G01N27/28
Filed: 1996-04-06
Abstract: PROBLEM TO BE SOLVED: To obtain a color display method in which the visual recognition of a pH distribution in a pH range is performed easily and precisely by a method wherein the color of the pH image is matched to the degree of the color development of a pH indicator. SOLUTION: From a two-dimensional pH measurement part 31, pH distribution data (a) in which a two-dimensional address and a pH in a measuring place (i.e., coordinates) are paired is output. The pH distribution data (a) from the two-dimensional pH measurement part 31 and data (b) from an indicator- color-change library 33 are input to a processing unit 32. The indicator-color- change library 33 is composed of a memory such as a ROM or the like, and a reference table in which a pH is contrasted with a color for every pH indicator is stored as the color change data (b). The processing unit 32 outputs a color display control signal (c) for every address on the basis of the pH distribution data (a) and the color change data (b).  In a two-dimensional pH image display device 34, a two-dimensional pH distribution image is displayed on a color display screen on the basis of the color display control signal (c) from the processing unit 32 so as to match the degree of the color development of the pH indicator.

Title: Semiconductor memory device
Inventor: KIMOTO MASAYOSHI
IPC: H01L27/102
Filed: 1986-05-14
Abstract: PURPOSE:To improve the writing speed of a P-N-P cell type ECL RAM, by making the impurity concentration of an epitaxial layer in a cell forming region larger than the impurity concentration of an epitaxial layer in a peripheral- circuit forming region. CONSTITUTION:The impurity concentration of a memory-cell forming part 14a of an epitaxial layer on an ECL RAM substrate is made high. Another pert 14b of the epitaxial layer is a region for forming a peripheral circuit for the RAM and a bonding pad. The concentration of impurities at this part is as usual. In this constitution, since the concentration of the N-type impurities in the epitaxial layer (collector regions of Q3 and Q4) of a memory cell is high, the recombination speed of holes (minority carriers) generated in the current conducting state becomes high (time change dp/dt of holes is proportional to electron concentration (n)). Therefore, increase in collector potential Vc of a transistor on the ON side becomes quick, and a writing time DELTA becomes short.

Filed: 1985-05-24
Abstract: PURPOSE:To form pulsated ion beams of a good controlability, by pulsating a relative potential applied between an ion emitter chip, and a drawing electrode or a control electrode. CONSTITUTION:An accelerating power source 6 and a pulse power source 7 are connected in series between an ion emitter chip 1 and a drawing electrode 4, and the output voltage of the pulse power source 6 is kept at a high DC voltage near the threshold voltage of the ion source property.

Abstract: PURPOSE:To operate the device higly accurately in a suitable sensitivity region regardless of the intensity of the light signal to an image sensor, by detecting the optical state of the device in real time, and performing automatic gain control (AGC). CONSTITUTION:A numeral 8 indicates a horizontal shift register HR, a numeral 9 indicates a driving transistor and a numeral 10 indicates an automatic gain control means having an amplifier. When a light signal is inputted hv to an image sensor, the electric charge generated in a photodiode 2 flows into a potential well in a storage gate 4. The charge is stored once.

The automatic gain control means 10, which detects the decreasing rate of the potential of the storage gate 4, is connected, and the signal is sent to a timing system. The charge storing time is adjusted so that the time is short when the incident light is intense and the time is long when the incident light is weak.
