  • Patent number: 8085242
    Abstract: An input control device and an image forming apparatus capable of providing an easy-to-use operating environment even for a user having difficulties operating such conventional devices and apparatuses due to his/her height, color vision deficiency, weak vision, use of a wheelchair, and the like is disclosed. In the input control device, based on the detected distance between an instruction item on the display and an operation direction element (such as a user's finger), the display mode of the instruction item is changed (by, for example, changing positions, colors, and combinations). Further, as the operation direction element approaches, the size of the instruction item on the display becomes larger, thereby improving the operability especially for a user with color vision deficiency or weak vision.

  • Patent number: 8047165
    Abstract: A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.

  • Patent number: 8037851
    Abstract: A heat accumulator (1) is formed by connecting a first container (4) and a second container (5) using a spring (6). The first container (4) has a wall-shaped inner side wall that corresponds to the shape of a cylinder bore wall (7). Provided on this inner side wall is a flexible structural part (8). The flexible structural part (8) is formed of highly elastic resin. The second container (5) has a similar structure. A heat storage medium within the first container (4) and the second container (5) absorbs heat, which generates a change of phase from a solid to a liquid. When this happens, the volume of the heat storage medium increases. The increase in the heat storage medium projects the flexible structural part (8), and separates the first container (4) and the second container (5) from the cylinder bore wall (7).

  • Publication number: 20110228347
    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.

  • Publication number: 20110126784
    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: 7775196
    Abstract: A fuel supply apparatus that supplies fuel to an internal combustion engine by injecting liquid fuel from a fuel injection valve into a suction port is configured by a microbubble generator that generates microbubbles and an ultrasonic wave generator that generates an ultrasonic wave depending on a gas in the microbubbles generated by the microbubble generator. In the fuel supply apparatus, the generated microbubbles are mixed into the liquid fuel that is supplied to the fuel injection valve, and the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave depending on the driving state of the internal combustion engine. When the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave, a temperature of the liquid fuel is raised instantaneously due to contraction of the microbubbles.
