Abstract

A protein according to one embodiment of the present invention has a photoactivated adenylate cyclase activity and has an amino acid sequence of SEQ ID NO: 1 in which 1-18 amino acid residues are deleted from the C-terminal or an amino acid sequence having a sequence identity of 90% therewith. The present invention provides a novel photoactivated adenylate cyclase having a higher photoactivation efficiency than wild-type OaPAC proteins.

Abstract

Provided are a device for quantum beam generation capable of continuously generating a quantum beam automatically, a method for quantum beam generation, and a device for laser fusion. A quantum beam generating device comprises a target supplying device (4a) to supply a target (2a) to a chamber (3a), a target monitoring device (5a) to monitor the target (2a) in the chamber (3a), a laser beam emitting device (6a) to expose the target (2a) in the chamber (3a) to a laser beam (8a), and a control device (7a). The target supplying device (4a) emits the target (2a) in a preset emission direction (3d) in the chamber (3a) for which the emission timing is controlled by the control device (7a). The control device (7a) calculates an exposure point (4d) for the laser beam (8a), calculates when the target (2a) arrives at the exposure point (4d), and causes the laser beam emitting device (6a) to emit a laser beam on the basis of the exposure point (4d) and the arrival timing.

Abstract

The purpose of the present invention is to allow comparatively easy control of energy supplied to plasma at the center of a target. A laser fusion device comprises: a target shell supplying device (3) for supplying a target shell (Tg1) to a chamber (2); a target shell monitoring device (4) for monitoring the orientation and position of the target shell (Tg1); a compressing laser output device (5a) and the like for irradiating the target shell (Tg1) with a compressing laser beam (LS1); and a heating laser output device (6) for irradiating the target shell (Tg1), after the compressing laser beam (LS1), with a heating laser beam (LS3). The target shell (Tg1) has a hollow spherical shape, the interior thereof is provided with a substantially spherical cavity (Sp), at least one through-hole (H1) is provided to connect the exterior and the cavity (Sp), and the outer surface (Sf1) of the target shell (Tg1) includes an irradiation region (Ar1, Ar2) where the compressing laser beam irradiation is expected to hit.

Abstract

[PROBLEMS] To provide a skull cut-off device capable of performing craniotomy operation easily in safety while reducing burden on the patient and closing the head only with a bone flap without relying upon a fixing tool. [MEANS OR SOLVING PROBLEMS] A skull cut-off device for cutting off a skull by means of laser comprises a body (1) for emitting laser (R) introduced from a laser oscillator (200) through an optical fiber (300) from an exit opening (1a) provided at the distal end, a contact portion (2) provided in the body (1) to determine the posture of the body (1) such that a predetermined distance is set between the surface of the skull (P) and the exit opening (1a) by touching the surface of the skull in a predetermined mode, a supporting lever (31) of a predetermined length extending from the body (1) toward the emitting direction of the laser (R) while avoiding the optical path of the laser (R), and a light interception board (32) provided at the distal end of the supporting lever (31) to block farther advance of the laser (R) by interfering with the laser beam path.
