20100129253 | OIL PUMP ROTOR - An oil pump rotor includes an inner rotor formed with n (n: a natural number) external teeth, and an outer rotor formed with n+1 internal teeth which are in meshing engagement with each of the external teeth. And the oil pump rotor is used in an oil pump that includes a casing having a suction port for drawing in fluid and a discharge port for discharging fluid and conveys the fluid by drawing in and discharging the fluid due to changes in volumes of cells formed between surfaces of the internal teeth and surfaces of the external teeth during rotations of the rotors under meshing engagement therebetween. And the tooth profile of the external teeth of the inner rotor is formed by a deformation in the circumferential direction and a deformation in the radial direction applied to a profile defined by a mathematical curve with the deformation in the circumferential direction is applied while maintaining the distance between the radius (R | 05-27-2010 |
20110014078 | OIL PUMP - An oil pump includes: an inner rotor rotatable with a drive shaft in a unified manner on a drive-rotation axis; an outer rotor which has inner teeth configured to engage with outer teeth of the inner rotor and is rotatable about a driven axis eccentric to the drive-rotation axis; and an adjustment ring for rotatably supporting the outer rotor. A guide means which allows the adjustment ring to rotate about the driven axis, while allowing the driven axis to revolve about the drive-rotation axis, is formed of: first and second arm portions provided on the adjustment ring; and first and second guide faces with which the first and second arm portions are brought into slidable contact. | 01-20-2011 |

20120057444 | Information Processing Apparatus and Operation Control Method of an Information Processing Apparatus - According to one embodiment, an information processing apparatus includes an optical disc drive, a data processing module which executes data processing using the optical disc drive, and a power supply management module which manages supply of power to the optical disc drive. The data processing module interrogates the power supply management module about the optical disc drive at the time of activation, and waits until an operating system recognizes the optical disc drive when an instruction is received from the power supply management module in response to an interrogation. The instruction instructs to wait until the operating system recognizes the optical disc drive. The power supply management module shifts the optical disc drive to a power supply on state and returns the instruction to the data processing module, if the optical disc drive is in a power supply off state when the interrogation is received. | 03-08-2012 |
20130229337 | ELECTRONIC DEVICE, ELECTRONIC DEVICE CONTROLLING METHOD, COMPUTER PROGRAM PRODUCT - According to one embodiment, an electronic device includes: a display controller; a user presence determination module; a reference elapsed time storage module; an interval time setting module; and a display controller. The display controller causes a display to display various types of information. The user presence determination module determines whether a user is present at a first time interval. The reference elapsed time storage module stores therein a second time for changing an operation mode to a power saving mode based on a time elapsed from when a user operation is ceased to be detected. The interval time setting module sets the first time interval shorter than the second time based on the second time stored in the reference elapsed time storage module. The display controller turns off the display if the user presence determination module determines that the user is absent. | 09-05-2013 |
20130232568 | ELECTRONIC DEVICE, ELECTRONIC DEVICE CONTROLLING METHOD, AND COMPUTER PROGRAM PRODUCT - According to one embodiment, electronic device includes: display controller; user presence determination module; user authentication module; and controller. The user presence determination module determines presence of a user based on image data received from the camera while dominating access to a camera. The user authentication module dominates access to the camera, if the display is put in a screen lock state and to perform a user authentication based on the image data. The controller turns off the display if the user present determination module determines that the user is absent and while the display has not been put in the screen lock state, and to cause the user presence determination module to release the access to the camera and to put the display in the screen lock state before turning on the display if it is determined after the display is turned off that the user is present. | 09-05-2013 |
20140122912 | INFORMATION PROCESSING APPARATUS AND OPERATION CONTROL METHOD - According to one embodiment, an information processing apparatus detects whether or not a person is in front of a screen of a display arranged on a front surface of a second housing. When the second housing is set at a first position where the screen of the display and an upper surface of a first housing are exposed, the apparatus enables a control function for controlling a state of the display to transit from an ON state to an OFF state based on the detection result. When the second housing is set at a second position where the screen of the display is exposed and at least a part of the upper surface is covered with a back surface of the second housing, the apparatus disables the control function. | 05-01-2014 |
