Title: Gas sensor and gas analyzing method using the same
Inventor: TAKEDA SHIRO
IPC: G01N21/35
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To simply measure a long-term average environment state by exposing a gas sensor having a copper hydroxide thin layer of copper hydroxide provided in the surface thereof to measuring environment for a constant period to measure the change of copper hydroxide. SOLUTION: Since copper hydroxide formed on the surface of metal copper by anodic oxidation has a thin constant thickness of several μm and measurement by a reflection type infrared absorption spectrum is easy and there is reproducibility, the reaction amt. of copper hydroxide with a harmful substance to be measured can be accurately measured different from a molded pellet of a copper hydroxide powder. The thickness of a copper hydroxide surface layer is pref. about 0.5-4 μm. As gas to be measured, nitric acid gas, sulfuric acid gas containing sulfuric acid mist, gas of a chlorine compd. such as hydrochloric acid or the like, chlorine gas, hydrogen sulfide gas, ammonia gas or a mixture of these gases are designated. This gas sensor is allowed to stand at a contaminant measuring place and the copper compd. on the surface of the gas sensor is analyzed after a definite period.  This gas sensor can be fixed to clothing to be used for the purpose of always monitoring a contaminated state.

Title: Ink-jet recorder
Inventor: NUMATA YASUHIRO
IPC: B41J2/18
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To automatically optimize recording after replacing a recording head. SOLUTION: Head replacement is detected by providing a serial number of a recording head (step S308). Since head characteristic information read out from the recording head (color information, shading information, or the like) is stored when the head is replaced (step S310), recording after the recording head replacement can be optimized automatically without the need of operation by a user. Moreover, since the recovery operation of the head is conducted automatically when the head is replaced, recording after the recording head replacement can easily be optimized without the need of operation by a user.

Title: Method and device for evaluating color of colored water
Inventor: URUSHIGAKI KENJI
IPC: G01N21/31
Filed: 1994-10-26
Abstract: PURPOSE: To provide a method and device for evaluating color of colored water to achieve a uniform standard and at the same time, applicable to the color evaluation of industrial drain by performing such a numerical evaluation as evaluating to be low when the maximum absorption wavelength of a light absorption curve obtained from a colored water is long and to be high when the wavelength is short. CONSTITUTION: An operation device 1 obtains light absorption curves A and B for the wavelength of a colored water and at the same time, calculates integral operation values (a') and (b') of the light absorption curves A and B in a wavelength range (d) according to the color characteristics from the light absorption curves A and B. A compensation operator 3 compensates the operation value of the operation device 1 and the output to an evaluation value output device 2 is performed, for example, by a data file. The evaluation output device 2 calculates color evaluation values according to an operation expression which is set in advance from the integral operation values (a') and (b').  As a result, even if, for example, the integral operation values (a') and (b') are equal, the color evaluation value is calculated to be a higher value since it is considered that the colored water with lower maximum absorption wavelengths (a) and (b) is caused by an energetically stable substance even if the integral operation values (a') and (b') are equal to each other.

IPC: G03G15/01
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a mechanism for preventing an operator from adding a toner to a toner hopper which is not empty yet. SOLUTION: An engine controller confirms a magenta toner hopper is empty, rotates a selector shaft 21 to a magenta clutch coupling position, couples a magenta clutch and rotates a magenta cam 100 to its replenishing position. Since the robe of the magenta cam 100 does not exist at a position for holding a cam follower member 102, the member 102 is pushed down, and a lockout member 112 is turned to that replenishing position. When the lockout member 112 temporarily comes to that replenishing position, the operator can engage a toner cartridge 24 at the position of the toner hopper, the base of the toner cartridge 24 can be coupled with a lid interlock latch, and the toner cartridge 24 can be ejected by opening a lid through a lid slider knob.

Title: Projection exposure method and projection aligner
Inventor: KONUMA OSAMU
IPC: G03F7/20
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a method of projection exposure and a projection aligner with a stable focus image which has a large depth of focus by compensating distortion in an image face, that is changed in each illumination mode shifted by an illumination-light deforming means or a distortion of the image face caused by an exposure environment or exposure history.

Title: Numerical control system for high-speed working
Inventor: KAWAMURA HIDEAKI
IPC: G05B19/18
Filed: 1985-11-25
Abstract: PURPOSE:To shorten the pre-processing time and to eliminate the high-speed working stagnation by discriminating the desired pre-processing from the undesired one at the time of high-speed working and carrying out only the desired pre-processing at the time of high-speed working when a high-speed working command is delivered. CONSTITUTION:A CPU of a numerical controller reads an NC command out of an NC tape at the time of pre-processing and decides whether this NC command is equal to an essential instruction code or not. Then the CPU carries out the corresponding processing when an essential command code is confirmed. If not, it is checked whether a high-speed mode is commanded or not. When a high-speed mode is confirmed, the pre-processing is through. If not, it is checked whether the NC command read for the normal processing is equal to a selection command code or not. When a selection command code is confirmed, the processing corresponding to this code is carried out. Then the pre- processing is through after production of the execution data. If no selection command code is decided, the execution data is produced directly and the pre- processing is through. In such a way, the pre-processing quantity is reduced by carrying out the desired processing only.

Title: Metal corrosion inhibitor
Inventor: ITO KENICHI
IPC: C23F11/16
Filed: 1993-10-20
Abstract: PURPOSE:To obtain a metal corrosion inhibitor which generates less foaming at the time of using it in an aqueous system and does not contain any heavy metal, phosphorus and nitrogen and has excellent corrosion inhibition effect by using an S- alkylthiocarboxylic acid having a specified range of number of carbon atoms and not using any halide as a component of the inhibitor. CONSTITUTION:This corrosion inhibitor is a metal corrosion inhibitor which contains an S-alkylthiocarboxylic acid having 12 to 18 carbon atoms as the active component and no halide, and can be used in an aqueous system. The S-alkylthiocarboxylic acid has preferably 12 to 16 carbon atoms and preferably in particular 14 carbon atoms. The alkyl group is optionally either branched or straight chained. However, the S- alkylthiocarboxylic acid having a straight chain alkyl group shows superior corrosion inhibition effect as compared with that having a branched chain alkyl group provided that each of the alkyl groups has the same number of carbon atoms. When the alkyl group has <12 carbon atoms, the corrosion inhibition effect of the inhibitor is reduced since the hydrophobic group that forms a coating film on the surface of a metal is short in length. On the other hand, when the alkyl group has >18 carbon atoms, the corrosion inhibition effect becomes insufficient since the solubility of the inhibitor in water is reduced.
