摘要:
A method for preparation of a cycloheptimidazole compound having formula (5), wherein: R4 is a lower alkyl group, comprising reacting a compound of formula (1), with an alkylamidine hydrochloride.
摘要:
The present invention relates to compounds of formula (1). wherein: R1 is hydrogen atom or lower alkyl group, X is bromine atom or chlorine atom; and which are useful for the preparation of the cycloheptanoides such as cycloheptimidazole derivatives. The compound having formula (1) is obtained in a single pot by the reaction of a trialkylsilylether compound with a dihalocarbene which, in turn, is prepared from the reaction of chloroform or bromoform in the presence of base.

A probing test device is provided for contacting a plurality of probes with pads on a semiconductor wafer to be tested and supplying a test signal to a tester comprising a CPU for previously storing, as a reference image, the image signal obtained when the probes are correctly contacted with the electrode pads. The probing test device includes a mechanism for positioning these probes to be contacted with the pads on the wafer by moving the tested wafer relative to the probes, an optical system for image sensing those portions at which the probes are contacted with the pads, and a mechanism for positioning the optical system near to the pads by moving the optical system relative to the wafer. The CPU performs a comparison of the reference image signal with that image signal sensed for those portions at which the probes are contacted with the pads. which is picked up by the optical system to confirm whether or not both of these images coincide with each other, wherein the wafer is moved relative to the probes by the wafer positioning mechanism responsive to the result confirmed by the CPU.
摘要:
The present invention relates to heat-resisting layer-constructions consisting of base substrates such as plates, boards and sheets, and silicone polymers having high contents of aryl radicals painted and thermally cured to adhere on the surfaces of the base substrates, and the method of preparing the same.
摘要:
An article with multi-layer protective coatings, comprising a substrate and two protective coating layers, in which said protective coating layers consist of a vacuum-coated ceramic layer and a resin layer, coated in any desired order.
摘要:
A device for narrowing the breadth of a sheet spring material in an apparatus for manufacturing a taper leaf spring by which the sheet spring is previously subjected to breadth narrowing operation with edge rollers before taper rolling.A shape for narrowing the breadth of a sheet spring material is calculated so that a product after rolling may be within the tolerance. Then, a shape of template thus obtained is detected by a pair of detecting rollers to regulate the interval between the work rollers automatically before taper rolling.
摘要:
The present invention provides a broadleaf perennial weed control agent for grass, which has a powerful herbicide effect on weeds that have proven difficult to control with conventional herbicides for grass and/or on weeds having resistance to conventional herbicides, and yet is safe for use on grasses; and a method for controlling broadleaf perennial weeds in grass by applying the control agent to the soil or the foliage.The present invention provides a broadleaf perennial weed control agent for grass, including a 1,5-diphenyl-1H-1,2,4-triazole-3-carboxamide derivative represented by a formula (1) as an active ingredient, and a method for controlling broadleaf perennial weeds in grass that includes applying the control agent to the soil or foliage: wherein R represents an alkyl group of 1 to 10 carbon atoms that may be substituted with a fluorine atom and the like, X1 represents a halogen atom or an alkyl group of 1 to 3 carbon atoms, X2 represents a hydrogen atom or a halogen atom, and Y1 and Y2 each independently represents a hydrogen atom or a fluorine atom.
摘要:
It is an object of the present invention to provide an electronic circuit apparatus in which mounting efficiency and connection stability of an electrolytic capacitor are compatible. An electronic circuit apparatus 5 of the present invention includes a board 60 with a circuit element 70 mounted thereto, a case 80 holding and surrounding the board 60, and a board mount connector (connector for mounting the electrolytic capacitor onto the board) 1 mounted onto the board 60 and holding the electrolytic capacitor 20. The board mount connector 1 includes a board connector 30 to be mounted onto the board and a holder 10 connected to the board connector 30 and holding the electrolytic capacitor 20 as an insulating holding body. The electrolytic capacitor 20 is mounted onto the board 60 via the board mount connector 1 by mounting the board connector 30 onto the board 60.
