  • Patent number: 9206002
    Abstract: A variable speed unit is driven by a drive unit to make a tooth-missing large gear of a sheet feed tooth-missing stage gear mesh with a small gear of an input stage gear rotating at a constant speed, to then rotate a rotating shaft of the feeding roller and a cam at a first speed to lift an intermediate plate. If a sheet stacked on the intermediate plate is pressed against the feeding roller, the variable speed unit makes a large gear of the input stage gear and a tooth-missing small gear of the sheet feed tooth-missing stage gear mesh with each other, so that the rotating shaft of the feeding roller is rotated at a second speed faster than the first speed to rotate the feeding roller at a fast speed.

    Abstract: According to an embodiment, an information processing apparatus includes a storage, an accepting unit, an analyzer, a determination unit, and an output controller. The storage stores therein one or more pieces of first feature information respectively representing features of one or more source codes, and one or more pieces of assistance information representing update situations of the source codes, in a corresponding manner. The accepting unit accepts input of second feature information representing a feature of a source code to be analyzed. The analyzer calculates similarity between the first feature information and the second feature information. The determination unit selects, based on the similarity, assistance information to be output, from the pieces of assistance information stored in the storage.

  • Patent number: 9121475
    Abstract: A drive transmission apparatus in which, when immobilization of a preceding gear (21) by a solenoid (22) is canceled, an urging portion urges the preceding gear (21) to rotate in a direction in which the preceding gear (21) meshes with an input gear (24) which rotates at a constant velocity. An interlocking portion causes an output gear (20) to mesh with the input gear (24) in association with the rotation of the preceding gear (21), to rotate the output gear (20) at a low velocity, and to rotate the output gear (20) at a high velocity when the output gear (20) rotates by a predetermined amount.

  • Publication number: 20150242207
    Abstract: In a system according to any one of embodiments, program structure information may include interval information. Each interval information may include source code position information indicating a successive region on a source code of a target program and parent-child information for specifying a parent-child relationship with respect to the interval information. The program structure information may include a reference interval without a parent. A processing unit may specify the number of parents existing between each interval information and the reference interval as a depth of each interval information from the reference interval, and create display information by arranging the interval information on a coordinate system defined by a first axis representing depth from the reference interval and a second axis representing the parent-child relationship based on the depth from the reference and the parent-child information.

  • Publication number: 20150168894
    Abstract: In a fixing device, an alternating current is caused to flow through a coil so as to causes an electrically conductive layer of a rotating member to generate heat, and an unfixed image on a recording medium is heat fixed onto the recording medium by the heat generated by the electrically conductive layer. A frequency range of the alternating current is from 20.5 kHz to 100 kHz. With respect to a generatrix direction of the rotating member, a magnetic member and a spirally shaped portion of the coil have lengths, with which the magnetic member and the spirally shaped portion extend beyond both end portions of the rotating member.

  • Publication number: 20150090563
    Abstract: Provided is a driving force transmission device including: an actuator (22) that, in a case where one of a first annular gear (11), a second annular gear (14), and a carrier (16) is an input member, another one is an output member, and the remaining one is a rotational member, causes one of the input member and the output member to rotate integrally with the rotational member. When driving force is inputted from the drive source to the input member and input member is rotated unidirectionally, the rotation direction of the output member in the case where one of the input member and the output member rotates integrally with the rotational member is reversed with respect to that in a case where one of the input member and the output member does not rotate integrally with the rotational member.
