  • Patent number: 8877813
    Abstract: It is intended to provide an antiinflammatory and analgesic preparation for external use whereby side effects of a nonsteroidal antiinflammatory and analgesic drug on the skin can be regulated, the nonsteroidal antiinflammatory and analgesic drug can be prevented from degeneration with time due to a dibenzoylmethane derivative contained as an UV absorbent therein, the dibenzoylmethane derivative can be prevented from crystallization and sedimentation due to an oily phase component contained therein, and the inherent effects of the nonsteroidal anti-inflammatory and analgesic drug can be fully exerted without showing skin irritation caused by the oily phase component, an emulsifier and a thickener.

  • Patent number: 8109296
    Abstract: A fluid flow passage structure and a manufacturing method therefor are provided, in which fluid flow passages can be easily produced employing a simple structure and process, while also being suitable for reducing the weight thereof. Wire members having a predetermined pattern are disposed between a first block member and a second block member. Airtight and fluidtight hermetic fluid flow passages are formed between such members, by forming the first block member, the second block member, and the wire members together as an integral structure.

  • Patent number: 7923124
    Abstract: A laminated structure is formed by stacking a first block member, an intermediate member, and a second block member together in this order, and then mutually joining each of the members. Further, by setting the elastic constant of the intermediate member to be greater than the elastic constants of the first block member and the second block member, deformation of grooves, which are formed in the first block member, is minimized.

  • Publication number: 20090302695
    Abstract: An object of the present invention is to effectively cool the generation of heat of a resin molding armature, especially to effectively cool the generation of heat of a coil in an electric motor having a resin molding armature and in an electric tool into which the electric motor is incorporated. In order to effectively cool the generation of heat of a resin molding armature 2a, especially in order to effectively cool the generation of heat of a coil 2e, an open groove 2j is provided for each slot 2g on an outer circumferential face of a molding resin filling layer 9a, which is filled into the slot 2g of a core 2f, in which the coil 2e is embedded. A molding die used for forming a molding resin filling layer 9a is made up of four members which can be split in four sliding directions (in the radial direction of the core).

  • Publication number: 20090140196
    Abstract: A manufacturing method for a fluid pressure device and a fluid pressure device are provided, in which joints are diffusion bonded to a valve body. In the fluid pressure device, the joints are inserted into an inlet port and an outlet port formed in the valve body, and heating is performed to generate a temperature difference between the valve body and the joints, whereupon by diffusion bonding of the joints into a wall of the valve body in which the inlet port and the outlet port are formed, both members are bonded.
