摘要:
A wheel comprises a main body, a tread making a contact with a top face of the rail head of a rail, and a flange. At least at a portion of the wheel tread which is in contact with the rail, there is provided a tread-forming component formed of a ceramic-particle-dispersion reinforced aluminum composite material, which has ceramic particles mixed in an aluminum alloy. The tread-forming component is formed in a ring shape, fitted into a tread-forming component receiving portion and fixed to the main body by a fixing member.
摘要:
A surface acoustic device is formed by cutting a piezoelectric wafer having a number of input and output electrodes on one surface thereof such that at least one end of the device has a bevel adjacent the upper surface. The bevel suppresses the reflection of surface waves. The bevel may be formed by a rotating cutter having a central disc and opposite frustoconical cutters.
摘要:
An attenuated feline recombinant herpesvirus 1 (FHV-1), which is prepared by identifying gene regions in the genome wherein inserted foreign genes can be expressed without affecting the replication of FHV-1 and has least two types of foreign nucleic acid sequences inserted thereinto, usable as a vector virus or a vaccine. In this attenuated recombinant FHV-1, at least two types of foreign genes are inserted in such a manner as allowing the expression into two different gene regions exerting no lethal effect on the proliferation of the virus in the feline herpesvirus 1 genome.
摘要:
Through inhibition of the multiplication of pathogenic bacteria and inactivation of bacterial self-induced factors, the balance of intestinal flora is improved to thereby promote regulation of animal intestinal functions and enable prevention/treatment of infection disease caused by such pathogenic bacteria. Accordingly, a pharmaceutical containing Bacillus thuringiensis is administered to animals, and animals are allowed to ingest food or feed containing Bacillus thuringiensis.
摘要:
A surface acoustic wave resonator comprising at least two interdigital electro-acoustic transducers found between two sets of reflective gratings on a crystalline substrate. The period of the electrodes of the transducers is selected to be less than the period of the reflective gratings.

Problem to be Solved: The present invention provides a novel mucosal adjuvant.Solution: The present invention provides a mucosal adjuvant composition containing at least a composition comprising molecules having a molecular weight in a range of 100 to 300 kDa obtained from cells or culture fluid of Bordetella bronchiseptica. Administration of the mucosal adjuvant composition to a non-human animal at a surface of the mucous membrane can enhance immunity at the surface of mucous membrane. Therefore preventive effects against trans-mucosal infection can be increased by administering an inactivated vaccine against trans-mucosal infection and the mucosal adjuvant composition to a non-human animal at a surface of mucous membrane. The present invention is effective for preventing trans-mucosal infections, including one or more infections of e.g., canine parainfluenza, canine adenovirus, canine coronavirus, canine parvovirus, canine distemper virus, canine herpesvirus, reovirus and pneumovirus.
摘要:
An object of the present invention is to improve the milk yield and/or milk quality of a ruminant for milk production, to prevent or treat a perinatal disease of a ruminant, and to improve the reproductivity of a ruminant. In order to solve the above-mentioned problem, the following is provided. An agent for improving at least one of milk yield and milk quality of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol. An agent for preventing or treating a perinatal disease of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol. An agent for improving reproductivity of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol.
