Title: Carbon dioxide gas detection indicator
Inventor: SATO HISASHI
IPC: G01N21/78
Filed: 1987-09-11
Abstract: PURPOSE:To make it possible to detect carbon dioxide gas, which is included in gas or liquid simply at a low cost without collecting the carbon dioxide, by dissolving a basic compound, impregnating phenolphthalein reagent, which is made to be basic and colored, into a base material, and adjusting moisture activity. CONSTITUTION:A basic compound is dissolved and phenolphthalein reagent is made to be basic and colored. The reagent is impregnated into a base material, and moisture activity is adjusted. Thereafter, a part of or the entire part of the base material is covered with a transparent plastic thin film, which is characterized by substantial moisture impermeability and high carbon dioxide permeability. The base material is completed screened from the outside. The concentration of the discoloring carbon dioxide is adjusted by adjusting the quantity of the dissolving basic compound, i.e., by adjusting pH. Thus, the carbon dioxide gas, which is included in gas or liquid, can be detected simply at a low cost.

Title: Method for formation of floating gate member of nonvolatile memory cell and floating gate member
Inventor: BIINNYON UU
IPC: H01L29/792
Filed: 1991-08-15
Abstract: PURPOSE: To reduce the number of tail bits by providing small and uniform particles within a boundary area between a floating gate and tunnel oxide. CONSTITUTION: P<31> is injected into a strip 38a up to a level of about (1 to 8)×10<14> /cm<2> . A thin polysilicon layer 45 is lightly doped, making polysilicon particles in the thin polysilicon layer to be smaller in size. Therefore, a part formed of the thin polysilicon layer 45 of the strip 38a, that is, the particle size of a part closest to a tunnel oxide 39 becomes small because the layer 45 is thin and it is lightly doped. As a result, the change in threshold voltage between the gates after deletion is reduced greatly and the distribution of deleted voltage becomes dense. Therefore the number of tail bits having a lower threshold voltage than the desired value or the number of tail bits which intend to fail after cycling can be reduced to the most extent.

Title: Method for evaluating degree of deterioration in steel material surface by using image processing
Inventor: HIROSE TSUYOSHI
IPC: G01N21/27
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To enable quantitative determination of corroded and deteriorated conditions by correcting the brightness using an image processing based on R, B and G signals of colors from a picture taken for deterioration in the surface of a hot dip galvanized steel material. SOLUTION: The brightness is standardized in a picture of a deteriorated state of a hot dip galvanized steel material taken under varied conditions. To achieve this, the colors of a gray card taken in simultaneously with the photographing of an object to be analyzed are corrected and developed using ordinary R(red), G(green), and B(blue) as three principles of additive color mixture of a Munsell color meter to meet the requirement of R=G=B. Thereafter, a digital image signal is taken into a calculator using a scanner or the like to analyze the deteriorated state of the surface of the steel material into signals R, B and G which are displayed by an image processing.  In this case, the deteriorated state of the steel material is standardized to an arbitrary brightness (vector length) 2<n> -1 (n is arbitrary number) and the resulting values (R', G' and B') are substituted for a formula to obtain the results. This enables evaluation free from photographing conditions.

Title: Multi-target tracking device
Inventor: MORITA YASUTOSHI
IPC: G01S7/02
Filed: 1988-09-13
Abstract: PURPOSE:To prevent occurrence of a tracking impossible state of the title device when the movement of a target is large and, at the same time, to maintain the tracking accuracy of the device at a fixed level by calculating the transmitting beam width corresponding to an inferred target distance. CONSTITUTION:Signals received through a phased array antenna 1 are inputted through a receiver 3 and a distance measurement circuit 5 measures the distance to a target from the signals. A transmitting beam width calculation circuit 8 calculates a beam width suitable for tracking the target from the distance information of the circuit 5 and inputs the beam width to a beam directivity controller 7. The controller 7 produces phase data corresponding to the beam width and outputs the data to the antenna 1. As a result, the target is irradiated with a beam and the reflected wave of the beam from the target is received. Since the target is tracked in such way, occurrence of tracking impossible state can be prevented even when the movement of the target is large or the error in the angle measurement made to the target is large. In addition. the tracking accuracy can be maintained at a fixed level by controlling the gain of the antenna by changing the beam width.
