A quantum device includes a quantum chip and an interposer on which the quantum chip is located. The interposer includes an interposer substrate and an interposer wiring layer. The interposer wiring layer is disposed on a surface of the interposer substrate on a side on which the quantum chip is located.

Abstract: In producing a mono-cell, the mono-cell is formed from separator, positive electrode, separator and negative electrode which are joined to each other. Negative electrode is joined, one by one, to one surface of strip of continuously conveyed separator. Positive electrode having different size from negative electrode is joined, one by one, to the other surface of separator. Strip of continuously conveyed second separator is joined to one of negative and positive electrodes. Position of negative electrode joined to separator is detected by negative electrode joining position detection cameras, and joining position of positive electrode is corrected by positive electrode alignment mechanism with this detected position of negative electrode being a reference during conveyance of positive electrode along positive electrode conveyance direction.

Abstract: A mono-cell is formed of a separator, a positive electrode, a separator and a negative electrode bonded to one another. Each separator includes a ceramic layer facing the positive electrode. On a lower surface and an upper surface of the positive electrode, an adhesive is applied at points lined up on a straight line along a width direction orthogonal to a conveyance direction. When an application length is defined as the product of the number of application points of the adhesive lined up in the width direction and the application diameter of each adhesive, the number of application points and the application diameter are set such that a value obtained by dividing, by the application length, a force applied to each ceramic layer based on acceleration and the weight of the separator during suction and conveyance becomes smaller than the necessary peeling strength per unit length of the ceramic layer.

Abstract: An optical fiber cable unit has an optical fiber cable obtained by binding a plurality of optical fibers and transmits a laser beam using transmission paths having the optical fibers, respectively. The optical fiber cable unit includes: an input-side connection unit that inputs the laser beam to the optical fibers; a one-end-side connection unit fixed to one end of the optical fiber cable and connected to the input-side connection unit; an other-end-side connection unit fixed to the other end of the optical fiber cable; and an output-side connection unit to which the other-end-side connection unit is connected and in which the laser beam from the optical fibers is output. The input-side connection unit has a switching mechanism that switches the transmission paths for transmitting the laser beam.

Abstract: Since an investigation apparatus is connected through a cable and is remotely operated, the cable may be caught by an obstacle, thereby limiting a movement range of the investigation apparatus. An investigation system 15 includes an investigation apparatus 50 which moves to a position where an investigation target is investigated, by using a traveling section 51 and a support apparatus 30 which moves to a position where letting-off and winding of a cable 14 for an investigation apparatus which is connected to the investigation apparatus 50 are performed, by using a traveling section 31. The investigation apparatus 50 outputs an image of the investigation target which is captured by a camera section 53, to an investigation apparatus controller 40 via the cable 14 for an investigation apparatus.

Abstract: A continuously cast slab with a rectangular cross section, and made of high alloy containing Cr of 20 to 30 mass %, Ni of 30 to 50 mass %, and at least one of Mo and W as Mo+0.5W of 1.5 mass % or more is subjected to blooming and billet-making to yield a round bar having a diameter of 150 to 400 mm as a starting material of the seamless tube. The blooming and billet-making process is performed under a condition satisfying a relation of 1.3?H/D?1.8 where a short side length of the cross section of the cast slab is defined as H (mm), and the diameter of the round bar is defined as D (mm). The round bar is pierced-rolled to make a hollow blank; the hollow blank tube is elongation-rolled, and then diameter-adjusting-rolled to make the seamless tube, thereby preventing end cracking during piercing-rolling, and increasing yield.

Abstract: A distributor for an internal combustion engine includes a housing in which a distributor rotor is supported on a shaft for distributing a generated high voltage to ignition plugs through electrodes, and a distributor cap covers electrical devices of the distributor. The distributor cap of an insulating material is composed of an inner distributor cap and outer distributor cap of a high strength material space is formed between the walls of outer distributor cap and inner distributor cap for preventing dewing. A number of T-shaped projections may be provided along an inner surface of the outer distributor cap for defining the space, with the projections being fixed to the inner distributor cap or a spacer may be sandwiched between the inner and outer distributor caps.
