  • Patent number: 7938704
    Abstract: A hook assembly is arranged to engage with an engaged member to fix a first housing to a second housing of an outboard motor. The hook assembly includes a rotation shaft, a hook member, a lever, and a weight. The rotation shaft is rotatably mounted on the first housing. A recessed portion is provided in the hook member. The recessed portion is arranged to open in first rotation direction. The recessed portion engages with the engaged member. The lever extends from the rotation shaft in a second rotation direction opposite to the first rotation direction of the recessed portion. The weight regulates the rotation of the hook member in the second rotation direction when the hook member and the engaged member are engaged together. The arrangement provides a highly-operable hook assembly for the outboard motor that prevents disengagement even when an obstacle collides with the outboard motor during traveling of a boat.

  • Publication number: 20100234385
    Abstract: It is thought that applications and use of tetrahydrobiopterin (BH4), which is used as a pharmaceutical, will expand due to its superior efficacy. However, in addition to BH4 being extremely expensive, since it is unstable with respect to oxidation, applications other than pharmaceuticals are considered to be difficult. Further, it is difficult for BH4 to permeate through a blood-brain barrier, so that BH4 concentrations in the brain tend not to increase under the present conditions. Biopterins are oxidized form of BH4, stable to oxidation, easy to handle, and can be produced inexpensively. The inventors found that administration of biopterin can be expected to demonstrate effects equal to or greater than those of administration of BH4.

  • Patent number: 7704109
    Abstract: A mounting structure for cables for a boat propulsion unit that enables easy insertion of cables into a pass-through hole, as well as highly reliable water-sealing is provided in a bottom cowling of the boat propulsion unit. The cables are inserted in through-holes in a rubber grommet by opening up a slit in the rubber grommet, and then inserting the rubber grommet in a pass-through hole in the port section. The rubber grommet is fit into the pass-through hole in the pressurized condition to water-seal the pass-through hole. The pass-through hole is molded integrally with the bottom cowling. A retaining plate is wrapped around the rubber grommet to prevent the slit from opening up, and the grommet is accommodated in the pass-through hole together with the retainer plate. Then, the retainer plate is fastened to the port section by mounting bolts. Thus, the rubber grommet is fixed within the pass-through hole, and provides water-sealing by filling the gap around the cables within the pass-through hole.

  • Patent number: 7697025
    Abstract: Positional and elevation data obtained from a camera unit is correlated with coordinates in an entire image display portion, used as a GUI having positional information to select a specified image with a mouse. Which frame this corresponds to in the entire image is calculated, and further, the position within the clicked frame is calculated. The calculated positional information is converted into positional information and elevation data of the frame. The camera unit is controlled with the positional information and elevation data from the camera unit, and an image of a range indicated by a specified image display frame superimposed on the display portion is taken, and stored and/or displayed. This allows confirmation an image of a range to be photographed beforehand, and the user can tell the relation between the range capable of acquiring images and the photography range at a glance, so desired portions can be continuously monitored.

  • Publication number: 20100069713
    Abstract: An electronic endoscope system includes an electronic endoscope having a CMOS image sensor on the tip of an insertion section, a light source device for illuminating the interior of a patient's body, and a processing device for reading out image signals from the CMOS image sensor. The electronic endoscope system can operate with a standard imaging mode and a special imaging mode. When the time taken to read out the image signals from all the pixels in the standard mode is defined as T, the light source device in the special imaging mode emits illumination light in every first half period T/2 while switching a wavelength of the illumination light between two different wavebands. In every second half period T/2, the processing device reads out the image signals from the half of the pixels.

  • Publication number: 20090314518
    Abstract: In a cable insertion structure for an outboard motor, a pawl section and a supporting section of a resinous cap are inserted from the inside of a cowling into a communicating hole of a rubber grommet, and the pawl section is fitted into a recess. Then, the communicating section of the rubber grommet is sandwiched between the pawl section and the pressing section, and thus the resinous cap is fixed to the rubber grommet. In the above-described state, a cable is inserted from an insertion hole of the resinous cap into a cable housing section of the rubber grommet. A clip band is fastened to a groove of the cable housing section to fix the cable housing section to the cable. The cable insertion structure for an outboard motor prevents a rubber grommet from coming off even when an external force that pulls the cable is applied.
