摘要:
A rare earth metal-iron group metal target for a magneto-optical disk is produced by mixing power (a) produced by the rapid quenching treatment of an alloy composed of at least one rare earth metal and at least one iron group metal in a composition range which permits the formation of an eutectic structure, with powder (b) from at least one iron group metal in an amount necessary for meeting the composition requirements of the target; and subjecting the resulting mixture to pressure sintering in vacuum or in an inert gas atmosphere at a temperature lower than a liquid phase-appearing temperature of the mixture to produce a rare earth metal-iron group metal intermetallic bonding layer betwen the particles.

Provided is an agent for treating or preventing urinary frequency, urinary urgency and urinary, incontinence which are associated with overactive bladder, a lower urinary tract disease such as interstitial cystitis and chronic prostatitis accompanied by lower urinary tract pain, and various diseases accompanied by pain. A novel azolecarboxamide derivative in which an azole ring such as thioazole or oxazole is bonded to a benzene ring, pyridine ring or pyrimidine ring through carboxamide was confirmed to have a potent trkA receptor-inhibitory activity and found to be an agent for treating or preventing lower urinary tract disease and various diseases accompanied by pain, which is excellent in efficacy and safety, and thus the present invention was accomplished.
摘要:
It is intended to provide a compound useful as a GnRH receptor antagonist. The inventors further investigated propane-1,3-dione derivatives. As a result, they confirmed that a compound having a benzene ring or a thiophene ring substituted with a group represented by —SO2—R3 in a propane-1,3-dione derivative having 2-(1,3-dihydro-2H-benzimidazol-2-ylidene) has an excellent GnRH receptor antagonistic effect and accomplished the present invention. Because the compound of the present invention has a potent GnRH receptor antagonistic effect, it is useful for the treatment of sex hormone-dependent diseases, particularly GnRH-related diseases. Further, because the compound of the present invention has an excellent metabolic stability in human and few drug interactions, therefore it has preferable characteristics as a pharmaceutical used for the above-mentioned diseases.

A wiring board includes a structure in which a plurality of wiring layers are stacked with insulating layers interposed therebetween, a plurality of pads for mounting an electronic component, the pads being formed on an outermost insulating layer on one surface side of the structure and exposed to the surface of the outermost insulating layer, and a recessed portion formed at a place corresponding to a mounting area for the electronic component. The recessed portion is formed in the outermost insulating layer at an area between the pads to which electrode terminals of the electronic component to be mounted are to be connected, respectively.
摘要:
Compounds useful as GnRH receptor antagonists are provided. The present inventors have further examined propane-1,3-dione derivatives and confirmed as a result that a propane-1,3-dione having 2-(1,3-dihydro-2H-benzimidazol-2-ylidene), or a compound which has benzene or thiophene ring substituted with a group derived from 1-hydroxymethyl, shows excellent availability, in addition to its excellent GnRH receptor antagonism, thereby accomplishing the invention. Since the compound of the invention shows excellent availability, in addition to its strong GnRH receptor antagonism, it can be expected that it exerts superior drug effect in the living body, and it is useful for the treatment of sex hormone dependent diseases such as prostate cancer, breast cancer, endometriosis, uterine leiomyoma, benign prostatic hypertrophy and the like. In addition, since the compound of the invention is excellent in metabolic stability in human and also is less in drug interaction, it has more desirable properties as a medicament to be used for the aforementioned diseases.

In a wiring board, a plurality of wiring layers and a plurality of insulating layers are alternately stacked. The wiring layers are electrically connected to one another through via holes formed in the insulating layers. The wiring board includes: a connection pad which is disposed on one of the wiring layers that is on the inner side of an outermost wiring layer; and an external connection terminal which is disposed on the connection pad, and which is projected from the surface of the wiring board. The external connection terminal is passed through the outermost wiring layer.
摘要:
To prevent or alleviate the occurrence of stress in the junction portion between the semiconductor element and the semiconductor package for mounting the semiconductor element, so that cracks will not occur even when there is mounted a semiconductor element having a low strength. A package for semiconductor devices is formed as a laminate of many layers including a plurality of conducting layers and insulating resin layers that are alternately laminated one upon the other and having, on one surface of the laminate, a portion for mounting a semiconductor element. The whole region or some region(s) of the insulating resin layers of the laminate, including at least the portion for mounting the semiconductor element and the peripheries thereof, are constituted by a prepreg obtained by impregnating a woven fabric of a liquid crystal polymer with an insulating resin.
