Title: Stainless steel plate with antibacterial characteristic, and its production
Inventor: MIYAKUSU KATSUHISA
IPC: A01N59/16
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a stainless steel imported with excellent antibacterial characteristics without deteriorating productivity by utilizing the antibacterial action of Mo. SOLUTION: This stainless steel plate contains, as a steel material, 0.2 to 10 wt.% Mo, and Mo is concentrated, as a simple substance or an oxide, in an amount of >=0.2 atomic % in a surface film or in an amount of >=1.0 atomic % in a surface layer part, and the resultant Mo-concentrated layer is allowed to appear at the surface. The Mo-concentrated surface film or surface layer part can be formed by annealing at 600 to 1250 deg.C. Although it is preferable to adopt bright annealing which causes no deterioration in the Mo-concentrated layer in a descaling stage, antibacterial characteristics can be recovered, even in the case of annealed and acid-picked stainless steel, by allowing the surface layer having the Mo-concentrated layer to appear by means of grinding in the subsequent stage.

Abstract: PURPOSE:To perform adequate injection of NH3 in a noncatalytic denitration method by measuring the temp. of a reaction space as well as the concn. of NOx after denitration and the amt. of waste gas by predicting the amt. of the NOx to be generated and the concn. of leak NH3 and controlling the injecting rate of NH3 according thereto. CONSTITUTION:The past injecting rate of NOx and NH3 is initially set and the temp. of the waste gas in a reaction space and the amt. of the waste gas are measured. The NOx after denitration is measured and the predicted amt. of NOx is calculated. On the other hand, whether the amt. of the NOx at certain time is within the permissible difference of the target value or not is checked from the DELTAt obtd. by dividing specified time by L and the integrated value of the NOx. Whether the incremental amt. of the NOx in the time DELTAt is within the permissible value of the target value or not is checked. Leak NH3 is calculated from the present time T and NH3/NOx ratio and whether said NH3 is smaller than E or not is checked. Whether the injecting rate of the NH3 is smaller than a set value M or not is also checked. When the leak NH3 is larger than E, the NOx target value is set and changed to a slightly higher value.

Filed: 1990-03-08
Abstract: PURPOSE:To prevent unnatural display by providing a predetermined delay time at every change of one cycle with respect to the change on and after the second level when the display of a level meter changes by two or more levels by the first processing. CONSTITUTION:The gas detection part 90 of the computer provided to this apparatus compares the resistance value Rs detected by a gas sensor with the lowermost limit level Ro.I1 of a reference value to detect the presence of gas. AT this time, as the resistance value Rs, the average value 68 of values always detected for 0.5 sec at a 0.5 sec interval is used. When gas whose concn. is the level Ro.I1 or more is detected, the resistance value is compared with refer ence detection levels Ro.I1 - Ro.I5 of five stages to detect concn. levels and the parameter variables K1 - K5 are compared with the previous variables K1 - K5 detected before 5 sec to discriminate whether there are changes of two levels or more and, when there are the changes of two levels or more at the same time, a delay part 92 provides a delay time of a 0.5 sec interval to the change from the second stage. By this method, an LED processing part 96 and a buzzer processing part 98 can display gas concn. in a natural state corresponding to variable K1 - K5 values.

Title: Scanning-type probe microscope
Inventor: HONMA KATSUNORI
IPC: G01N37/00
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain high detection sensitivity without fixing a probe and a piezoelectric body in one piece by flexibly pinching the probe with first and second elastic bodies and allowing the first elastic body to have a piezoelectric body. SOLUTION: In an elastic body 201 for pinching a probe 101 flexibly, a piezoelectric body 202 is formed on a surface, and an elastic body 206 also plays a role of a vibrator. A probe 101 that is excited up and down in the elastic body 206 is bent and vibrated with a part in contact with the elastic body 201 as a support, and at the same time the elastic body 201 causes bending deformation with the contact part as a pressure cone apex since compliance is large. Therefore, at the moment when the probe 101 moves up and down, the elastic body 201 is bent and deformed in a peripheral direction, the piezoelectric body 202 expands and contracts to generate a bipolar voltage. In this case, when the frequency of the elastic body 206 is swept, the vibration amplitude of the probe 101 increases closer to a mechanical, natural frequency.  As the amplitude increases, the expansion and contraction of the piezoelectric body 202 also increases and a generated voltage increases. By monitoring the change in the generated voltage, the resonance characteristics of the probe 101 can be detected.

Abstract: PURPOSE:To enable a sufficient correction of the variations of electron rays to be achieved even when acceleration voltage and current are widely changed by installing detectores for detecting the variations of electron rays in two positions between an electron gun and a sample. CONSTITUTION:In addition to a variation detector 5 for primary electron rays, a detector 8 is installed in a second convergent lens 7. A diaphragm 16 installed between a first and the second convergent lenses 6 and 7, restricts the detection angle of the second detector 8. Signals from the detectors 5 and 8 are amplified with amplifiers 11a and 11b respectively, and the amplified signals are subjected to selection by a signal-selecting circuit 17a. The thus selected amplified signals are subjected to correction of the variations of primary electron rays by a signal-treating circuit 14, and the corrected signals are sent to a displayer 15. Among the primary electron rays, those indicated by solid lines are of low acceleration voltage condition and are detected with the first detector 5. Electron rays 4c indicated by dotted lines are of high acceleration voltage condition and are detected with the second detector 8. Therefore the signal-setecting circuit 17a performs selection according to the acceleration voltage condition.
