Abstract: A method for manufacturing a peeled substrate has a laser condensing step for focusing laser light at a prescribed depth from the surface of a substrate and a positioning step for moving and positioning a laser condenser relative to the substrate, the method involving forming a processed layer in the substrate. The laser condensing step includes a laser light adjustment step in which a diffraction optical element is used to branch the laser light into a plurality of branched laser beams, and at least one of the branched laser beams is branched such that the intensity thereof differs from the other branched laser beams. The processed layer is elongated using the branched laser beam having a relatively high intensity among the plurality of branched laser beams to process the substrate, and the elongation of the processed layer is restrained using the branched laser beams having a relatively low intensity.

Abstract: Provided is a linker for both screening assessment of the candidate clones without using enzymes, and to provide an in vitro selection method using thereof. Also, provided is a high-speed photo-crosslinking linker for molecular interaction analysis and in vitro selection comprising a backbone and a side chain. The backbone comprises a solid-phase binding site located at the 5′ terminus for forming a bond with a solid-phase; a solid-phase cleavage site for releasing the entire solid-phase at the site; a side chain linking site for linking a side chain; a high-speed photo-crosslinking site for linking the backbone to mRNA having a sequence complementary thereof via photo-cros slinking; and a reverse transcription initiation region located adjacent to the side chain linking site at the 3′ terminus of the backbone. The side chain comprises a fluorescent label, a protein binding site located at the free terminus thereof; and a binding site with the backbone.

Abstract: An acceleration device can prevent abnormal acceleration of a vehicle even when an accelerator pedal is erroneously abnormally stepped on instead of a brake pedal, and alert a driver of occurrence of erroneously stepping on the accelerator pedal. Assuming that a driver erroneously steps on an accelerator pedal hard instead of a brake pedal, a magnet of a fixation part of a transmission/blocking mechanism and a magnetic opposing surface of a movable part are disengaged and separated from each other. Accordingly, movement of the accelerator pedal with respect to an accelerator lever is blocked, and the accelerator lever is returned to an idling state due to the action of the accelerator mechanism. Also, an impact and sound of the disengagement of the magnet is transmitted to the driver, and the foot takes a position different from a normal position. Accordingly, the driver can notice erroneous stepping on the accelerator pedal.
