  • Patent number: 9269335
    Abstract: An installation structure for an acoustic transducer configured to push and pull a vibrated body and having a magnetic-path forming portion; a vibrating unit; and a connector having at least one joint portion configured to connect two members such that axes of the two members are inclined relative to each other by bending at the at least one joint portion, the at least one joint portion having an urging portion configured to generate an urging force by which a pushing-side driving portion of a first member connected to one side of the at least one joint portion urges a pushing-side driven portion of a second member connected on another side of the at least one joint portion in a pushing direction and an urging force by which a pulling-side driving portion of the first member urges a pulling-side driven portion of the second member in a pulling direction.

  • Patent number: 9255579
    Abstract: It is intended to provide a vacuum pump so that without upsizing the vacuum pump, noise and vibration are reduced, heat dissipation property is secured, and the casing is downsized. Therefore, at least one turning part is provided in an exhausting path formed in a casing body. The casing body is formed of a material whose thermal conductivity is higher than that of a rotor and vanes, and a cylinder part where the vanes slide is press fitted in the casing body.

  • Publication number: 20150218987
    Abstract: An air dryer includes a supporting base, a drying agent container, and an outer cover. The supporting base includes an inlet for receiving compressed air to be subject to a drying process and an outlet for delivering the processed compressed air that has undergone the drying process. The drying agent container is a container supported on the supporting base, contains a drying agent in the interior, and enables the drying process to be performed by passing the compressed air from the inlet through the drying agent. The outer cover surrounds the outer side of the drying agent container on the supporting base and defines a chamber for storing the compressed air between itself and the drying agent container. The supporting base includes first and second mounting surfaces, which are oriented in different directions, and a plurality of inlets, which are oriented in different directions and receive the compressed air.

  • Publication number: 20150062335
    Abstract: A radio communication apparatus includes a radio transmitting/receiving unit having a directional antenna and a storage unit storing reference image data and captured image data obtained by an imaging unit. The imaging unit has an optical axis oriented in the same direction as the radio wave direction of the directional antenna and captures an image related to a line of sight of the other opposed radio communication apparatus. The radio communication apparatus further includes an image processing unit comparing the reference image data with the captured image data and a control unit detecting, from the comparison result, and informing that an obstacle is traveling toward the aforementioned radio wave direction.

  • Patent number: 8879127
    Abstract: A first light source and a second light source are arranged so that a protrusion direction of a first terminal from a first supporting body and a protrusion direction of a second terminal from a second supporting body are different when viewed in the longitudinal direction of a light guide. The first light source and the second light source are arranged so as to reduce a protrusion direction of the first supporting body and the second supporting body in a predetermined direction from an area where the first light source and the second light source overlap when viewed in the longitudinal direction of the light guide.

  • Patent number: 8681398
    Abstract: A protruding locking pawl is provided at an end of a light guide which corresponds to a first light input surface. A recessed locking portion is formed in a frame so that the locking pawl can be locked in the locking portion. A light blocking member is slidably loosely inserted into a position where the light blocking member covers a longitudinal end of the light guide which corresponds to a second light input surface. Even if expansion and contraction occurs in the longitudinal direction of the light guide, the design dimensions of a first gap A and a second gap B can be maintained; the first gap A is formed between the first light input surface and a first light source, and the second gap B formed between the second light input surface and a second light source. Therefore, possible leakage current can be prevented.
