  • Patent number: 7733146
    Abstract: A delay line appropriate for use in a POR circuit or other integrated circuit in a space environment combines three separate circuit techniques to improve performance without unnecessarily increasing circuit area or adding to manufacturing costs when compared to a simple inverter delay line. The delay line of the present invention uses the selective placement of capacitors throughout the delay line, one-sided current starving, and the incorporation of one-sided Schmitt trigger circuits. Performance of the delay line is substantially immune to SEGR events (“Single Event Gate Rupture”) and SET events (“Single Event Transients”). Spurious signals produced by SEGR and SET events are quickly and substantially attenuated.

  • Patent number: 7729932
    Abstract: A computer readable storage medium encoded with a project assessment program for assessing a project including a plurality of processes when executed by a computer computing forecasts of the project based on a set of information. At least one scheme by a user input is selected from a group of schemes including an estimation of mutual-correlation of estimated value pattern. Process planning information, up-to-date actual process information and forecast model information of each process included in the project is retrieved. The forecast model information of each process of the project is defined as probability distribution variations of a plurality of parameters of the processes, wherein the probability distribution variations are quantitative values of the project. Estimated values of variations in at least two parameters of the processes using the process planning information, the up-to-date actual process information and the forecast model information are computed.

  • Patent number: 7729647
    Abstract: An image forming apparatus includes a developer bearing member for transporting developer to an opposing position opposing an image bearing member. Regularly-disposed concave sections are formed on a surface of the developer bearing member. An alternating voltage that includes a first voltage for moving developer from the developer bearing member toward the image bearing member and a second voltage for moving developer from the image bearing member toward the developer bearing member is applied to the developer bearing member. A cycle period of the alternating voltage is smaller than or equal to a minimum width of the concave section in a circumferential direction of the developer bearing member divided by a moving velocity of a surface of the rotating developer bearing member.

  • Patent number: 7730479
    Abstract: In a cell-phone terminal for receiving an event and detecting an application corresponding to the event to notify and manage the event, a conflicting condition and a return priority are set to each of multiple applications in advance. On receiving the event making a request for activation of an application later in a status of having an application running in advance, an application management portion suspends the application based on a conflicting condition about the application, and stores return information on the application necessary to activate it again for each return priority in the case of operating the application. When the application is finished, the application management portion reads the return information in lowering order of the return priority and activates a corresponding application by using the return information.

  • Patent number: 7729430
    Abstract: An autodetect circuit for a router system includes an interface to two bidirectional serial links, an input multiplexer circuit coupled to one side of the link interface for receiving input data signals and clock signals, a receiver coupled to the input multiplexer circuit and to a receive FIFO, a state machine coupled to the receiver, a transmitter coupled to the state machine, a transmit FIFO, and to the other side of the link interface for transmitting output data, and a counter coupled to the state machine for controlling the input multiplexer circuit. The autodetect circuit determines which of the two links “A” or “B” is active and available for transmission. The counter is incremented whenever a link reset occurs. When the count reaches a predetermined maximum count value, a port enable signal is toggled from the default “A” link to the “B” link. When one port is enabled, any activity on the other port is ignored.

  • Patent number: 7724554
    Abstract: A semiconductor switch circuit is connected to a primary winding of a transformer having a secondary winding connected to a load. The semiconductor switch circuit has switches controlled by PWM to provide a controlled constant current. In the inventive inverter, constant current control is performed by PWM operation of the switches of the semiconductor switch circuit. The inverter cuts off electricity to the control circuit when putting the control circuit into a standby state if a run-stop signal gains a logical stop-state. At the same time as the run-stop signal gaining the stop-state, switch drive signals enabling the switches of the semiconductor switch circuit are turned off. Thus, over-current can be prevented from flowing in the load when the control circuit is put into the standby state.

  • Patent number: 7717633
    Abstract: In a sheet bundle printing system, a sheet is fed by peeling an uppermost sheet from a sheet bundle. A printing device has a printing head and a platen roller for printing on the sheet. An ink ribbon is fed through space between the printing head and the platen roller in parallel with the sheet at the time of printing thereon. The platen roller is moved back and forth relative to the printing head between a printing position in which the platen roller is urged into contact with the printing head and a contact-free position in which the platen roller is out of contact with the printing head. Ink-ribbon feeding is suspended in a manner interlocked with the relative movement of the printing head and the platen roller between the printing position and the contact-free position.

  • Patent number: 7719665
    Abstract: The invention is to provide a wavelength dispersion measuring method for an optical fiber capable of measuring a wavelength dispersion in a section extending from an incident end of the optical fiber to an arbitrary point along the way by using a scattering phenomenon in which a scattering coefficient at a local point on the optical fiber is independent of time. Incident light having a known spectral density function S(?) is caused to be incident on the optical waveguide, and a wavelength dispersion of the section extending from the incident end of the optical waveguide to the arbitrary point along the way by a correlational function between a signal being proportional to a scattered light amplitude generated at a first halfway point and a signal being proportional to a scattered light amplitude generated at a second halfway point.
