IPC: E02B1/00
Filed: 1993-11-18
Abstract: PURPOSE:To provide an elimination sheet which is installed to the surfaces of an off-shore structure in order to eliminate living creatures unavoidably sticking to an underwater area of the off-shore structure. CONSTITUTION:Air-tight tubes 3 covered with a flexible sheet 2 are installed at least to the surface of an under-water area 1a of a marine structure 1 where the air-tight tubes 3 are designed so that compressed air may be fed or exhaustible. The air-tight tubes 3 expanded with the compressed air produce cracks 5 and 6, large and small, on living creatures 4 or the like which stick to the surface of the flexible sheet 2, thereby eliminating the living creatures 4 or the like growing on the surface. The expansion and contraction resultant deformations of the flexible sheet 2 fore the living creatures sticking on the surface to be deformed, thereby forming various-sized cracks so that the deposited living creatures may be easily separated and removed.

Title: Thermal flowmeter
Inventor: TONAMI YOSHIYUKI
IPC: G01F1/698
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a high response thermal flow sensor in which the flow rate can be measured accurately while retarding the saturation of current flowing through a heater even in the region of high flow rate. SOLUTION: A heater, i.e., a first diode 31, and a temperature measuring element, i.e., a second diode 32, are formed on a same substrate 30. Since the first diode 31 is formed on the substrate 30 through a diaphragm (or a cross- linked structure part or a cantilever), it is insulated thermally from the substrate 30 and has low thermal capacity. On the other hand, the second diode 32 is coupled thermally with the substrate 30 and it is not heated easily. Voltage difference is detected across the heater, i.e., the first diode 31, and across the temperature measuring element, i.e., the second diode 32, and a current is fed forward through the first and second diodes 31, 32 at same current density.  Since the current flowing through the first diode 31 is substantially proportional to the root of fluid, the saturation of current is retarded as compared with a conventional thermal flow sensor.

Title: Crt display device
Inventor: TSUZUKI KICHIJI
IPC: H01J31/20
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve contrast together with the arrangement of index elements and to deal with a CRT in large size as well. SOLUTION: 49 pieces of index fluorescent bodies are arranged on a display screen, for example, and an index signal is detected by an index detection amplifier 12 by detecting beam scanning using a photodetector 114. Based on this index signal, a distortion quantity detection circuit 13 detects distortion quantity, it is calculated by an arithmetic circuit 14, and a convergence correction circuit 16 is controlled. The index expectation signal is supplied from a control circuit 15 to the arithmetic circuit 14. When an index expectation signal and a phase are deviated at the position of a specified index fluorescent body, convergence correction is performed by discriminating it that the display screen is distorted at that fluorescent body position.  Since it is not necessary to always perform index detection but it is enough only to perform the index detection at that fluorescent body position, contrast is improved.

Filed: 1987-11-17
Abstract: PURPOSE:To dispense with a compounding tank for a premix product, by carrying out the metering of a powdery feed ray material simultaneous to the metering and compounding of a drug-related minor ingredient, directly charging both components into a main mixer and mixing the components to form the objective assorted feed. CONSTITUTION:A drug-related minor ingredient metered by a micrometering apparatus 35 is mixed with its diluent in a high-speed micrometering mixer 49 or an apparatus performing the same action.

Title: Position controller for self-running vehicle
Inventor: KAMIMURA KENJI
IPC: G05D1/02
Filed: 1989-11-08
Abstract: PURPOSE:To always guide a free running vehicle with a high precision by using position information calculated by a first position arithmetic means at the time when the free running vehicle is placed in a section and using position information calculated by a second position arithmetic means to control the running at the time when it is placed on the outside of this area. CONSTITUTION:When a free running vehicle 1 exists in a section a1 surrounded with lines connecting reference points A to D, position information of the free running vehicle 1 calculated based on position information of reference points A to D and angles alpha to sigma of opening is selected; and when the free running vehicle 1 exists on the outside of the area a1, position information of the free running vehicle 1 calculated based on distances between two reference points and the free running vehicle 1 is selected to control the running. Thus, the free running vehicle 1 is guided up to an objective place with a high precision based on distance data and azimuth angles to two reference points though the free running vehicle 1 goes out of the section surrounded with three or more reference points.

Title: Column selection circuit
Inventor: JANG SEONG JIN
IPC: G11C11/4096
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To minimize a layout chip and to reduce a chip size by sharing a data bus line at a read-out time and a write-in time without constituting separate read-out bus line and write-in bus line. SOLUTION: When a control signal R for read operation and a column selection signal Y become high, the data of a bit line and an inverse bit line are transmitted to a data bus line and an inverse data bus line. When a write-in enable signal WE for write-in operation and the column selection signal Y become high, the data on the data bus line are transmitted to a bit line through transistors TR 39a, 39d, and the data on the inverse data bus line are transmitted to the inverse bit line through the transistors TR 39e, 39h. At this time, since the control signal R for read operation isn't high, the TR 39b, 39e are off as it is, and a path isn't generated between the data bus line and the inverse data bus line.

The aging treatment can be executed after the ward working or after the direct solution treatment. The amt. of it to be cold-worked can be reduced not so as to adversely affect its SCC resistance compared to the material on the same strength level by the conventional reheating solution treating method.

Title: Printing method
Inventor: TANIMOTO MICHIAKI
IPC: B65H35/06
Filed: 1985-12-23
Abstract: PURPOSE:To eliminate a wasteful label, by driving a pasteboard running by a predetermined distance, so that a boundary part between the printed label and unprinted label comes to a cutter position, while the pasteboard, after it is cut, reversely running by the predetermined distance and printing the leading label. CONSTITUTION:In order to position a boundary part between the last printed label 14 and the top unprinted label 16 in the bottom of a cutter 4, a pasteboard 2 is driven running by a distance l to a side of the cutter 4. Since a running distance (k) of the pasteboard 2, when a stepping motor 32 is rotated by one turn, is known, a condition as shown in the drawing is obtained by forwardly rotating the stepping motor 32 by a distance l/k, and if the stepping motor 32 is reversed by the distance l/k after the pasteboard 2 is cut by energizing a solenoid 24 and lowering the cutter 4, the top unprinted label 16 returns to a printing position being printed. These controls are performed by a microcomputer. In this way, the waste of the label can be eliminated by preventing the label from being cut in its center and/or an unprinted label from being generated.

Since the crease of the starting carbon fiber is developed on the metal surface of the metal-coated carbon fiber chopped strand, the bonding area with the resin is increased by the crease to improve the adhesivity to the resin by the anchoring effect and give a molded article having good composite characteristics by molding a thermoplastic resin compounded with the chopped strand.

Filed: 1985-12-26
Abstract: PURPOSE:To form a fine through-hole precisely to an insulating resin film by selectively removing the insulating resin film through oxygen plasma etching, using a CVD film formed onto the insulating resin film as a mask. CONSTITUTION:A polyimide resin film 11 is applied onto an Al electrode film 9 shaped onto a semiconductor body, an SiN film 12 is formed onto the film 11 through a plasma CVD method, and a photo-resist film 13 is shaped selectively onto the film 12. The film 12 is taken away selectively, and the film 11 is gotten rid of selectively through oxygen plasma etching, employing the film 12 as a mask.
