Title: Production of welded steel tube excellent in wear resistance
Inventor: KOYUMIBA MOTOFUMI
IPC: B21C37/08
Filed: 1991-10-07
Abstract: PURPOSE:To efficiently obtain a welded steel tube excellent in wear resistance on the internal surface side by applying hot rolling to a double layer slab consisting of an outer layer material and an inner layer material, where steel compositions are respectively specified, subjecting the resulting stock to forming and to welding to form it into a steel tube, and performing heating and cooling under respectively specified conditions. CONSTITUTION:A slab composed of a high carbon low alloy steel containing, by weight, 0.2-0.6% C and 0.1-3.0% Mn is used as an outer layer material. Further, a slab composed of a low alloy steel containing 0.01-0.3% C, 0.1-3.0% Mn, and one or more kinds among 0.01-0.10% Nb, 0.01-0.10% V, 0.05-0.50% Mo, and 0.005-0.10% Ti is used as an inner layer material. A duble layer slab 3 consisting of the above slabs is hot-rolled, and the resulting stock for welded steel tube is formed into circular shape and then formed into a welded steel tube by means of welding. Subsequently, the whole tube is heated up to 800-1000 deg.C and cooled rapidly. By this method, hardening can be done and the high carbon steel layer, as the outer layer, alone can be hardened. Moreover, it is also effective to performing reheating up to 200-600 deg.C after rapid cooling, if necessary.

IPC: B41J2/485
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To improve the image quality by reducing occurrence of a stripe pattern or a false contour with a simple configuration. SOLUTION: An input image signal Si of a 256-value is corrected by an image correction signal at a correction circuit 11 into a corrected image signal Sc and it is fed to a 4-value circuit 12. The 4-value circuit 12 compares the corrected image signal with threshold levels Th1, Th2, Th3 to provide an output of a 4-value image signal So. Furthermore, the corrected image signal and the 4-value image signal So are fed to a 4-value error calculation circuit 13, in which a 4-value processing error of a picture element in question is calculated. Then a 4-value error signal Ser is fed to an error calculation circuit 14 and a threshold level control circuit 15.  The weight error calculation circuit 14 multiplies weight coefficients A-D with the 4-value error signal Ser to calculate a weight error around the picture element in question and the errors are accumulated in an error storage circuit 24. Then accumulated storage values eA-eD of the picture element in question are fed from the error storage circuit 24 to the correction circuit 11 as the image correction signal. Furthermore, the threshold level control circuit 15 generates the fluctuated threshold levels Th1, Th2, Th3 at random through bit arithmetic operation and gives them to the 4-value processing circuit 12.

Title: Output system for controller
Inventor: NOMURA KAZUMASA
IPC: G05B21/02
Filed: 1990-09-27
Abstract: PURPOSE:To prevent output from lowering even when an arithmetic cycle is extended by dividing a first cycle into plural second cycles with length shorter than that of the first cycle, and sample-outputting the same arithmetic result value at every second cycle via a hold circuit. CONSTITUTION:A digital arithmetic circuit 1 computes a controlled variable approaching a target at every cycle T2, and outputs it. However, a voltage goes down to V after the cycle T2 even when a hold value is, for example, V1 by outputting the controlled variable at every cycle T2. Therefore, an arithmetic result V1 of equivalent value is outputted at every cycle T3 that is 1/4 of the arithmetic cycle T2, and it is outputted as being held with the hold circuit 4. Since it is T2=4T3, the voltage drop of output goes to V'=1/4V, and it is enough to select the degree of setting of the cycle T3 for the cycle T2 to the level where the voltage drop V' can be neglected. In such a way, it is possible to suppress an output from going to low level even when the output cycle of arithmetic result is extended.

Abstract: PROBLEM TO BE SOLVED: To prevent a device from being broken owing to the depression of a wrong push-button lever while a push-button lever for stop ejection is pressed so as to take a cassette tape out of the device. SOLUTION: When a user presses a push-button lever 18 down toward an operation position while a push-button lever 20 is at a stop ejection position, a slide projection part 34 is pressed against a cam surface 42 and moves relatively from the start part to the end side of the cam surface 42 and then 1st and 2nd lock plates 26 and 48 move from start positions to unlock positions (right side) along an operation direction. At this time, a gap C is formed between the engagement part 64 of the 2nd lock plate 48 and the slide projection part 60 of the push-button lever 20. Since the 2nd lock plate 48 can rotate, the 1st lock plate 26 can move to a disengagement position.

Abstract: PURPOSE: To block contaminants from entering into a treating chamber and avoid degrading the cleanness therein. CONSTITUTION: A treating gas is fed from a first feed pipe 17 into a treating chamber 1, oxidizing gas is fed from a second feed pipe 18 into a space between this chamber and first outer wall 15, and reducing gas is fed from a third feed pipe 19 into a space between the wall 15 and second outer wall 16. To enter a contaminant such as heavy metal discharged from a heater 10 into the chamber 1, it must pass through the walls 15 and 16. An oxidizable component of the contaminant is oxidized by the oxidizing gas and exhausted from a second exhaust pipe 21 while a reducible component is reduced by the reducing gas and exhausted from a third exhaust pipe 22. Thus, no contaminant enters into the chamber 1.

Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To enable a pot to be placed on a heat plate in s stable state, and even heating is continued, the heat plate and the pot to be kept in good contact. SOLUTION: A top face S of a heat plate 6 provided with a heater 5 near its outer circumference is formed into a recessed face shape, whose center of the top face S is lower than the outer circumference part in a non-conductive normal temperature state. The top face S of the heat plate 6, in a high temperature state during power supply, is deformed into a substantially planar shape, in which the height of the center of the top face of the heat plate 6 is almost equal to that of the outer circumference part due to a difference in thermal expansion. As a result, even if a bottom shape of a pot A is flat or of recessed fade shape, the pot A can be placed in a stable state, and the pan A can be heated properly.

Abstract: PROBLEM TO BE SOLVED: To obtain an image processing and inspection apparatus which prevents an irregularity in an inspection result due to the degree of skill of an operator and whose inspection time can be shortened, by a method wherein a region obtained as a difference image as the difference in a binary image between a nondefective and a defective regarding an inspected object is set as an inspected region. SOLUTION: A nondefective and a defective regarding an inspected object are imaged respectively by an image input device (a CCD camera) 1. An analog image signal is converted into a digital signal by an A/D converter 2, and the digital signal is then binarized by a compactor 3 so as to be stored on an image memory 4. A CPU 5 uses a program retained in a memory 4, it aligns two binary images on a nondefective and a defective which are stored in the memory 4, and they are compared. Then, when the two binary images are aligned, the difference image of both binary images (an image whose pixel in coordinates in which the value of pixels of both images disagrees is used as a black pixel) is estimated to be generated by a defect part in the defective, and a region which is obtained as the difference image is used as a region to be inspected.  As a result, the defect part in the defective regarding the inspected object can be extracted.
