Systems and methods are provided for a flexible and scalable operating system achieving a fast boot. A computing system is described that includes a reserved static object memory configured to store predefined static threads, and a secure kernel configured to be executed in a fast boot mode. The secure kernel further may be configured to chain the static threads to a secure kernel thread queue stored in a secure kernel work memory, and to create temporary threads in the secure kernel work memory during the fast boot mode. The computing system may include a main kernel configured to be initialized by creating dynamic threads in a main kernel work memory during the fast boot mode. The main kernel may be configured to chain the static threads to a main kernel thread queue, and to assume control of the static threads from the secure kernel.

A joined article in which a first metal member made of a tungsten carbide base cemented carbide and a second metal member made of a martensitic stainless steel having a carbon equivalent of 2.5 to 3.5 and containing 0.030 mass % or less of sulfur are joined. The martensitic stainless steel having the carbon equivalent of 2.5 to 3.5 is preferably at least one selected from the group consisting of SUS431, SUS420J1, SUS420J2, SUS410, SUS410J1, S-STAR, PROVA-400, HPM38, STAVAX ESR, and SUS403 in the joined article. There is disclosed a joined article in which the lowering of the strength of a second metal member around a joining interface thereof is prevented.

The present invention provides an optical amplifying device which can be easily downsized, increased in output, and stabilized. An optical amplifying device 1A includes an optical amplifier 10A and an energy supplier 30. The optical amplifier 10A includes an optical amplifying medium 11 and a transparent medium 12. The energy supplier 30 supplies excitation energy (for example, excitation light) to the optical amplifying medium 11. The optical amplifying medium 11 is supplied with the excitation light to amplify light and output it. To-be-amplified light passes through the transparent medium 12 in the optical amplifying medium 11 a plurality of times. The transparent medium 12 can propagate the to-be-amplified light, for example, zigzag inside.

A single terahertz wave time-waveform measuring device 1 acquires information on an object to be measured 9 by using a terahertz wave, and includes a light source 11, a beam diameter adjuster 12, a separator 13, a terahertz wave generator 21, a light path length difference adjuster 31, a pulse front tilting unit 32, a polarizer 33, a wave synthesizer 41, an electro-optic crystal 42, an analyzer 43, and a photodetector 44. The terahertz wave generator 21 generates a pulse terahertz wave in response to an input of pump light and outputs the pulse terahertz wave. The pulse front tilting unit 32 makes pulse fronts of the terahertz wave and the probe light when being input into the electro-optic crystal 42 nonparallel to each other by tilting the pulse front of the probe light.

A joining jig 5 is constituted of a pair of flat-plate sandwiching portions 17, 18 including sandwiching faces 15 which sandwich therebetween a platy member laminate 4 prepared by laminating two platy members 2, 3 with providing a solder on a joined face between the platy members. The joining jig has a plurality of vapor inflow ports provided in the sandwiching face 15 so that surplus solder vapor on the joined face flows into the vapor inflow ports in a case where the platy member laminate 4 is heated while sandwiching the platy member laminate between the pair; vapor flow paths provided so that the vapor flow paths communicate with the vapor inflow ports; and vapor discharge ports 42 provided in the side surface of the joining jig so that the vapor discharge ports communicate with the vapor flow paths to discharge the vapor of the solder to the outside.
摘要:
A laser beam emitted from a laser source is projected onto a target set in a vacuum chamber while being focused by a focusing optical system. This results in generating fast particles, such as protons and emitting the particles from the target. A light measuring device measures plasma emission from the target upon in-focus irradiation with the laser beam and an analyzing device analyzes a measurement signal therefrom to assess a generation state of fast particles. Then the focusing optical system and target are controlled through optical system moving mechanism and target moving mechanism on the basis of the result of the analysis and feedback control is performed on the generation state of fast particles in the target. This realizes a fast particle generating apparatus capable of monitoring the generation state of fast particles in real time and thereby efficiently generating the fast particles.

A method for producing a bonded body of different materials of the present invention is a method for producing a bonded body of different materials (1), where two plate members (2 and 3) are bonded to each other, the method including: laminating two plate members (2 and 3) consisting of different materials to obtain a plate-member-laminated-body (4), and heating the plate-member-laminated-body (4). The method includes a step of heating the plate-member-laminated-body (4) while it is sandwiched between a pair of pressing dies (5). The pressing die (5) is made of a material having a heat transfer coefficient 1.5 times or more higher than that of at least one of the plate members (2 and 3) constituting the plate-member-laminated-body (4) and has a tapered part (6) between holding surface (15) which hold the plate-member-laminated-body (4) and a fixing end (16) for securing the pressing die (5). The outer diameter of the tapered part is reduced from the holding surface (15) toward the fixing end (16).

An image forming apparatus includes a fixing section and a guiding section. The guiding section includes first and second guiding members. The first guiding member is in a first conveyance path for a first recording sheet having a first width and contacts the first recording sheet to guide the first recording sheet to a discharging portion. The second guiding member is in an area of a second conveyance path a the second recording sheet having a second width larger than the first width and guides the second recording sheet to the discharge portion at an angle so that a contact length of the second recording sheet with the heating member along a conveyance direction of the second recording sheet is shorter than a contact length of the first recording sheet with the heating member along a conveyance direction of the first recording sheet.
