摘要:
A process for preparing a compound represented by general formulae (5) and (6) in the following reaction scheme or salts thereof, wherein R1 represents a protective group for a nitrogen atom; R2 represents a methanesulfonyl group or p-toluenesulfonyl group; R3 represents a hydrogen atom, an aralkyl group, or an alkyl group having 1 to 6 carbon atoms; and X represents a halogen atom. The above process is useful as an industrial process for preparing intermediates of anticoagulant aromatic amidine derivatives described in Japanese Patent Application Laid-Open (kokai) No. 208946/1993.
摘要:
An anticoagulant agent which comprises, as an active ingredient, an aromatic amidine derivative represented by the following general formula (1) or a salt thereof: ##STR1## wherein the group represented by ##STR2## is a group selected from indolyl, benzofuranyl, benzothienyl, benzimidazolyl, benzoxazolyl, benzothiazolyl, naphthyl, tetrahydronaphthyl and indanyl; X is a single bond, an oxygen atom, a sulfur atom or a carbonyl group; and Y is a saturated or unsaturated 5- or 6-membered heterocyclic moiety or cyclic hydrocarbon moiety optionally having a substituent group, an amino group optionally having a substituent group or an aminoalkyl group optionally having a substituent group.The inventive compound has a high anticoagulant capacity based on its excellent FXa inhibition activity.
摘要:
An antenna mounted on and retractable into a casing of a portable radio communication apparatus. When the antenna is pulled out of the casing, it plays the role of a .lambda./2 whip antenna. Even when the antenna is retracted into the casing, it has substantially the same gain as when pulled out from the casing.

A low and broadband shorted microstrip antenna is disclosed which is mainly applicable to a mobile body in a mobile communication system. A first grounding conductive sheet which faces a radiating conductive sheet is provided at both ends thereof with a second and a third grounding conductive sheets which are perpendicular to the first grounding conductive sheet, whereby a beam tilt characteristic of the antenna is improved. The passive element and a conductive stub are disposed atop the grounding conductive sheet. The passive element and the conductive stub face the radiating conductive element and serve to improve the impedance matching parameter of the microstrip antenna.

Unidirectivity is achieved in an antenna including a microstrip portion and a unipole portion. The microstrip portion includes a ground plane conductor, a radiation plane conductor dielectrically spaced from the ground plane conductor, and a conductive member connecting the radiation plane conductor to the ground plane conductor., The unipole portion of the antenna comprises a unipole coupled to the radiation plane conductor. The radiation fields of the microstrip and unipole portions intensify each other in a single direction to achieve unidirectivity.
摘要:
The present invention provides a stringed instrument capable of corresponding to a preference of a player of the stringed instrument, a purpose of performance, and so on as much as possible. A resonance box portion fabricated by an additive fabrication method and a neck portion protruding from the resonance box portion are included, and material constants at a desired area of the resonance box portion is made different from material constants at an adjacent area adjacent to the desired area step by step or continuously. Vibrational characteristics of the instrument are changed by the partial difference of the material constants, and thereby, the stringed instrument capable of corresponding to the preference of the player, the purpose of the performance, and so on is provided.
摘要:
A cellular phone includes upper casing 2 having a front surface with LCD panel 21 disposed thereon, lower casing 3 having a front surface with key pad 22 disposed thereon, and an antenna, upper and lower casings 2, 3 being openably and closably coupled to each other. First control plate 10 for reflecting electromagnetic waves is disposed in upper casing 2, and second control panel 11 for reflecting electromagnetic waves is disposed in lower casing 3. First control plate 10 and second control plate 11 comprise separate members which are independent of each other. When the cellular phone is in an unfolded state in which the angle formed between the front surface of upper casing 2 and the front surface of the lower casing 3 is maximum, first control plate 10 and second control plate 11 have a maximum projected area on the surfaces of upper and lower casings 2, 3.
摘要:
An image forming apparatus capable of obtaining an image of a desired quality by a simple method is provided with an image forming device for forming a toner image on a recording material, a plurality of pairs of fixing rollers provided to fix the toner image, a glossiness detecting sensor for detecting the state of the image on the recording material on which the toner image has been fixed, and a controller for controlling the fixing conditions of the plurality of pairs of fixing rollers, and has a first image check mode for fixing the toner image by one pair of fixing rollers of the plurality of pairs of fixing rollers, and a second image check mode for fixing the toner image by the plurality of pairs of fixing rollers, and the controller selects whether the second image check mode should be executed, on the basis of the result of the glossiness detecting sensor having detected the state of the image on the recording material on which the formed image has been fixed by the first image check mode.
