Title: Sustained-release underwater antifouling agent
Inventor: ARIMOTO YASUTAKA
IPC: C09D5/14
Filed: 1988-07-29
Abstract: PURPOSE:To obtain an underwater antifouling agent which, when applied to fishnets, ship bottoms or underwater structures, can prevent marine life from depositing on them for a long time, by mixing a higher aliphatic amine with a specified film-forming copolymer. CONSTITUTION:This sustained-release underwater antifouling agent comprises a higher aliphatic amine (A) of the formula [wherein R<1> is a 12-20C (unsaturated) aliphatic hydrocarbon group (its beta position may be substituted with an OH group), R<2> is H or a 1-3C alkyl, R<3> is H or a 1-3C alkyl (which may be substituted with an amino group), provided that when R<2> is a 1-3C alkyl, R<3> is the same as R<2>] (e.g., dimethylstearyalmine or didodecylmethylamine) and a copolymer (B) composed of 5-60wt.% polymerizable monobasic unsaturated carboxylic acid (a) [e.g., (meth)acrylic acid] and 95-40wt.% hydrophobic polymerizable unsaturated compound [e.g., (meth)acrylate)] and being capable of forming a film on the object to be prevented from fouling. By using copolymer B as a film-forming material, this antifouling agent can exhibit an antifouling activity for a long period of time because of its function of forming a salt of a free carboxyl group with the amine or the suitable hydrophobicity of the polymer.

Abstract: PURPOSE: To prevent the tear and/or damage of a web by equipping a variable speed motor which changes its speed according to change of the web in the extension part of a passage. CONSTITUTION: The motor of an additional driving device 9 reduces the possibility of the tear of the web between driving devices 6 and 8 rotates a central pulley 3' at a specified speed or the speed changing as a function of the advancing speed of the web 10 past the extension part of the web route extending between the driving devices 6 and 8, i.e., between the first infiltration position of the web to the liquid 2 and the final retreat position of the web from the liquid 2. In such a case, pulleys 4 merely lean on the adjacent part of the web 10 and pulls the respective six looped web parts. The respective looped web parts extend downward to the pulleys 4 from the pulleys 3(3') or the driving device 6 or upward from the pulleys 4 to the next pulleys 3(3') or the driving device 8. The weight of a support 5 contributes to the pulling effect of the pulleys 4.

IPC: H03K19/0175
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a back plane bus which transmits respective digital bits by making good use of a voltage difference between signal paths. SOLUTION: A current source is connected to one of bus drivers 110 and 120 of respective bus masters and a current sink is connected to the other in response to an input digital signal of a different binary type to vary the voltage difference on the bus. In response to an input digital signal of a binary type, the current source and current sink are insulated from the bus and then they are connected. The bus drivers 110 and 120 are selectively switched by a MOSFET switch. As a buffer driver circuit, a combination of a MOSFET and an NPN transistor for driving respective MOSFET switches with a high- peak current is used and speedy switching is performed. As the current source and sink of the bus drivers 110 and 120, a combination of a MOSFET and a NPN transistor is used so that the bus can operates at a low voltage level.

Title: Shear cutter and method in preparing for cutting of strip of sheet using the same
Inventor: KATAOKA AKIRA
IPC: B26D5/08
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce cutting preparation time by driving and rotating an upper blade for the required time at a high speed such that its speed difference to the travel speed of a strip of sheet attains time required value or higher. SOLUTION: As a strip of sheet S is fed, a hydraulic pressure cylinder device 33 is operated to flip a rocking arm 27 down to advance an upper blade 2 toward a lower blade 1. Also, as the upper blade 2 starts to advance, a motor is actuated so that the upper blade 2 is driven and rotated for a predetermined time at a speed such that its speed difference to the travel speed of the strip of sheet becomes not less than the required value. In this case, a clearance exists between the upper blade 2 and the lower blade 1 along the cross direction of the strip of sheet S. The edge of the upper blade 2 which rotates when advancing to a position indicated by the solid line is pressed against the strip S of sheet to bore a hole. Therefore, even if the strip of sheet S is thick, the hole can be bored by the upper rotating blade 2 just before the upper blade 2 meshes with the lower blade 1, so that the need for an operator to perform boring work is eliminated. Moreover, the upper and lower blades can be made to mesh with each other in a short time.

Abstract: PURPOSE:To detect the element concn. in a sample with high accuracy by subjecting the characteristic X-ray detected by irradiation of electron rays to the sample to the correction by the correction factor to be determined by an X-ray taking-out angle, electron ray accelerating voltage and the physical constant of the element. CONSTITUTION:The electron rays 1 are applied to the sample 2 and are two- dimensionally scanned. The characteristic X-ray radiated therefrom is detected by a detector 5. the X-ray intensity Is of the standard sample consisting of, for example, an element A alone and the X-ray intensity Iu of the measuring sample are detected and the relative intensity Ka=Iu/Is is determined. The correction factor is determined from the X-ray taking-out angle, electron ray accelerating voltage and the physical constant intrinsic to the element incorporated into the sample. The relative intensity and correction factor are similarly determined with the respective elements even if >=3 kinds of the elements are contained in the sample. The element concn. in the sample is detected by the arithmetic processing 7 from the relative intensity and the correction factor. Since the correction factor is determined, the detection of the elements with high accuracy is made possible even if >=3 elements are contained in the sample.

Title: Method and device for detecting pn pattern
Inventor: TAKAHASHI SHINGO
IPC: H04B1/7075
Filed: 1990-07-20
Abstract: PURPOSE:To reduce the burden of an arithmetic processing by reading a PN pattern data corresponding to an initial PN pattern number, for which coincidence is detected, and executing detection and confirmation while comparing this read data with the next received data. CONSTITUTION:The received data to be successively inputted are compared with the plural initial PN patterns held in a storing means 11 by an initial PN pattern detecting means 12. When the received data is a PN pattern sequence, as the result of this comparison, the data is coincident with any initial PN pattern and therefore, it is decided that the PN pattern is detected. For confirming whether this PN pattern detection is true or not, a reading means 13 reads out the PN pattern data from the storage device 11 concerning an initial PN pattern #K for which coincidence is detected, and a detecting and confirming means 14 compares this PN pattern data with the next inputted received data. Since these data are coincident when the above-mentioned PN pattern detection is true, the PN pattern detection can be confirmed. Thus, the burden of the arithmetic processing is reduced.
