  • Patent number: 7157298
    Abstract: A method of fabricating a surface emitting semiconductor laser includes the following steps. A first laminate of semiconductor layers and a second laminate of semiconductor layers are formed on a substrate. The first laminate includes a first reflection mirror layer of a first conduction type, an active region, a III-V semiconductor layer containing Al, and a second reflection mirror layer of a second conduction type, the second laminate being used for monitoring and having an oxidizable region. The first and second laminates are etched so as to form mesas on the substrate in which side surface of the III-V semiconductor layer contained in the first laminate is exposed. Oxidization of the III-V semiconductor layer from the side surface is started at an oxidization rate.

  • Patent number: 7158732
    Abstract: A method of using toner concentration (TC) as an active actuator in the tonal reproduction curve (TRC) controller, so that not only will the TRC controller maintain the TRC of the output, but also all the electrostatic actuators will not diverge, and the toner concentration will be within the latitude range of the xerographic system. The process ensures that the target of the toner concentration (TC) sensor will be changed properly in direction (up/down) and amplitude to compensate the TRC output of the print engine based on either reflective reactance readings and/or the level of the electrostatic actuators.

  • Patent number: 7159113
    Abstract: Distributors can verify a signature without acquisition of a certificate for each signer from the certificate authority. A signature part calculates a hash value of distribution information and sets it to a variable h (step S412). Signer private information is taken out from a first signer private information storage part and set to the variable d (step S413). A signature key information selection part takes out signature key information corresponding to a product identifier pid from a signature key information storage part and sets it to the variable t, n (step S414). A signature part calculates a first signature value to the variable h by use of signer private information d and sets it to the variable r1 (step S415). A distribution information generating part calculates a second signature value to the variable h by use of a signature key information t according to the variable h (step S416). A signature value to the final variable h is calculated by use of the results r1 and r2.

  • Patent number: 7158245
    Abstract: Disclosed is a printer which performs efficient power save control by keeping track of the condition of each client of the printer without having to send wasteful packets, that is, without affecting the network environment. The printer includes: a unit for monitoring packets flowing on a network, and for updating and storing a client-associated last receive time each time a packet is received from any client of the printer; a unit for determining, by referring to the stored client-associated last receive time, that any client from whose associated last receive time has elapsed a prescribed time is in an idle condition, and for computing a printer usage rate by summing the past average usage rates of the clients that have been determined not to be in an idle condition; and a unit for setting, based on the computed printer usage rate, the length of time allowed before a transition is made to the power save mode.

  • Patent number: 7159172
    Abstract: A display system uses so called rapid sequential visual presentation (RSVP) in which words are presented one after another in time, in a window for reading by a user. To provide context information, a thumbnail view of the document page or the section of text is also generated, and is used to indicate the location in the section of text of the word currently displayed in the RSVP window. In one example, an indicator is generated within the thumbnail view to show the position, and the indicator is moved automatically as the RSVP sequence advances. In another example, the thumbnail view is positioned in a background display pane behind the RSVP window, and the thumbnail view is moved relative to the RSVP window to indicate the current position in the text.

  • Patent number: 7158751
    Abstract: Systems and methods of registering a sheet in an image reproduction, e.g., a xerographic, device use sheet parameters regardless of the tray or bin with which the sheets are associated, separate tallies of sheet registration correction factors for both sides of a sheet, and use registration errors detected on a first side of a sheet to generate correction factors concerning proper registration of the second side of that sheet. In embodiments, the systems and methods average registration errors for one particular side of a plurality of sheets to obtain a damped error signal that is taken into account for registration of subsequent sheets on each respective sheet side. In embodiments, the systems and methods determine variations between actual and target system performance to affect subsequent sheet flow and registration.
