  • Patent number: 8579668
    Abstract: A vessel propulsion apparatus includes a nozzle, a deflector, and a forward bucket (hereinafter referred to as “F bucket”). In a state in which the F bucket is in a closed position and the deflector is positioned at a left side, water jetted obliquely rearward to the left from the deflector is guided by the F bucket in a left guiding direction that is tilted further to the left than a direction of jetting of water from the deflector. In a state in which the F bucket is in the closed position and the deflector is positioned at a right side, water jetted obliquely rearward to the right from the deflector is guided by the F bucket in a right guiding direction that is tilted further to the right than the direction of jetting of water from the deflector.

  • Patent number: 8553276
    Abstract: An image reading apparatus includes a contact glass having a light control glass part having transmittance changeable by an applied voltage; a scanner part reading an original placed on an original placement surface of the contact glass and outputting image data in a storage part; a projector part projecting image information onto the contact glass from a side opposite to the original placement surface; and a control part controlling the voltage applied to the light controlling glass part. When the scanner part is operated, the control part causes the transmittance of the contact glass to increase and the projector part stops projecting the image information, and when the scanner part is not operated, the control part causes the transmittance of the contact glass to decrease and the projector part projects the image data stored in the storage part onto the contact glass.

  • Patent number: 8513417
    Abstract: The problem to be solved by the present invention is to provide a highly-versatile method for producing a nitroxyl radical derivative, in which position-2 and position-6 in a TEMPO-based compound can be easily substituted, and further, a method for producing a nitroxyl radical derivative, in which a nitrogen nucleus is labeled with 15N. The above-described problem can be solved by reacting a triacetoneamine derivative with ketone or aldehyde in the presence of ammonium salt or a 15N-labeled compound thereof to obtain a 2,6-substituted-4-piperidone derivative.

  • Patent number: 8462393
    Abstract: An image reading apparatus includes a scanner part reading an original on a contact glass, and a projector part projecting image information onto the contact glass as first image displaying. The projector part projects thumbnails or an image to have an image processing operation carried out or be printed. The display part carries out second image displaying obtained from reducing the first image displaying in size. At a time of the scanner part being operated, transmittance of the contact glass is increased and the projector part stops projecting the image information, and at a time of the scanner part not being operated, the transmittance of the contact glass is decreased and the projector part carries out the first image displaying. Setting of the image processing operation for the image data is reflected on the first image displaying and the second image displaying.

  • Patent number: 8347846
    Abstract: A vehicle control system 10 includes a water pump 23 with an electromagnetic clutch, an oil relief device 25, an OCV 26, a water temperature sensor 31, and an ECU 11. The ECU 11 causes the electromagnetic clutch of the water pump 23 to be disengaged on the basis of the detection result detected by the water temperature sensor 31, and stops the coolant circulation. The ECU 11 instructs the OCV 26 to adjust the lubricant pressure to low by an oil relief device 25. The ECU 11 determines whether or not the adjustment of the lubricant pressure to low by the oil relief device 25 is stopped on the basis of the detection result detected by the water temperature sensor 31 when the engagement of the electromagnetic clutch of the water pump 23 continues for a given period.

  • Patent number: 8339358
    Abstract: An input apparatus for enabling a user to enter an instruction into a main apparatus has high durability and offers superior operability. The input apparatus includes a table device having a table with a variable size. An image of plural virtual keys that is adapted to the size of the table is projected by a projector unit onto the table. Position information about a finger of the user that is placed on the table is detected by a position detecting device contactlessly. One of the plural virtual keys that corresponds to the position of the finger of the user detected by the position detecting device is detected by a key detecting device based on information about the image of the plural virtual keys and a result of the detection made by the position detecting device.

  • Publication number: 20120204420
    Abstract: A method for manufacturing a wiring board, which prevents electrostatic destruction generated in a mask pattern, by employing a structured exposure mask at a low cost is provided. The method can comprise the steps of forming a photosensitive resin layer on an insulating layer located underneath a predetermined conductor layer, forming a plating resist by exposing and developing the photosensitive resin layer with an exposure light while an exposure mask is disposed on a surface of the photosensitive resin layer, forming a metal plating layer that has a conductor pattern formed by applying a metal plating to an opening of the plating resist, and removing the plating resist. The exposure mask may have a plurality of graphic patterns, and each corner of the graphic patterns maybe chamfered by 50 micrometers or more so that electrostatic destruction due to electric discharge between the adjacent graphic patterns is prevented.
