Abstract: The present invention aims to provide a method for producing a trans-polyisoprenoid which can increase trans rubber production. The present invention is directed to a method for producing a trans-polyisoprenoid in vitro, which involves the use of a gene coding for a trans-prenyltransferase (tPT) family protein and further involves the use of rubber particles bound to a protein encoded by the gene, or a method for producing a trans-polyisoprenoid, which includes introducing into a plant a vector including a promoter having a promoter activity that drives laticifer-specific gene expression and a gene coding for a tPT family protein linked to the promoter to express a protein encoded by the gene specifically in laticifers.

Abstract: A linear guide device including an actuator including: a base section; a slider slidably provided to the base section; and guide sections disposed between the base section and the slider in a state that the guide sections are extending in the sliding direction of the slider. DLC films are formed on the guide sections, and the guide sections are locked to the slider such that the guide section can slide in a state that the DLC films are applying a predetermined preload with respect to the base section.

Abstract: Provided is a method for producing a polyisoprenoid, which can increase natural rubber production by enhancing the rubber synthesis activity of rubber particles. The present invention provides methods for producing a polyisoprenoid using a gene coding for a cis-prenyltransferase (CPT) family protein, a gene coding for a Nogo-B receptor (NgBR) family protein and a gene coding for a rubber elongation factor (REF) family protein, specifically a method for producing a polyisoprenoid in vitro using rubber particles bound to proteins coded for by these genes, and a method for producing a polyisoprenoid in vivo using a recombinant organism (plant) having these genes introduced therein.

[Solution] A cell includes a solid oxide electrolyte layer 9, a fuel electrode layer 8 on one of the main surfaces of the electrolyte layer 9, and an oxygen electrode layer 10 on the other. The oxygen electrode layer 10 contains a plurality of pores, and the pore size distribution observed at a section of the oxygen electrode layer has at least three peaks (a first peak p1, a second peak p2 and a third peak p3). This structure leads to a cell, a cell stack, an electrochemical module and an electrochemical apparatus that can suppress decrease in output power.

Abstract: An electric actuator such that a nut threadedly engaged with a sliding screw shaft is displaced along an axial direction under the operation of a motor, the sliding screw shaft being made of a light metal or light metal alloy. A diamond-like carbon film is formed on at least either a portion of screw threads of the nut that is located at least within three threads from a starting end in the axial direction, or screw threads of the sliding screw shaft.

Abstract: A vacuum pad suctions a workpiece by utilizing a vacuum pressure, and includes a support member having a vacuum passage inside, a bellows secured to the support member, and a restriction member attached to an inner side of the bellows. When the bellows is contracted, the restriction member comes into the vacuum passage.

Abstract: A layered nut (10) comprises a plurality of thin nuts (12) formed with through-holes (16) having almost the same diameter. On the inner peripheral surface of each thin nut (12), a plurality of screw threads (18, 38) are formed at predetermined angular spacing so as to protrude toward the inside of the through-hole (16). In this case, the thin nuts (12) are layered along the direction of the central axis (14) so that the through-holes (16) become approximately coaxial. The outer peripheral surfaces of the layered thin nuts (12) are subjected to laser welding or the like, thereby joining the thin nuts (12) and completing the layered nut (10).

Abstract: A developer housing container includes a container main body, a moving wall, a sealing member, and at least one communicating mechanism. The container main body has an inner circumference surface which defines an internal space tubularly extending, and is provided with a developer discharge port. The moving wall has an outer circumference surface arranged to be opposed to the inner circumference surface, and a transport surface which defines a housing space. The moving wall moves in a first direction while transporting the developer toward the developer discharge port. At least one communicating mechanism is arranged at a predetermined position in the first direction in the container main body and allows the housing space and the internal space positioned more upstream of the moving wall in the first direction to communicate with each other by partly deforming the sealing member.
