Abstract: A chirality detector of the present invention for detecting chirality of chiral material, includes: a first electrode and a second electrode that are configured to apply a voltage to a subject containing the chiral material; a spin detection layer configured to be in contact with the subject; a power supply; and a control section. The power supply and the control section are configured to generate an electric field at the subject by applying the voltage between the first electrode and the second electrode. The control section is configured to detect a voltage generated in the spin detection layer in a direction that goes across a direction of the electric field or a voltage generated between the spin detection layer and the subject, and also is configured to detect chirality of the chiral material on the basis of the detected voltage.

Abstract: A more practical method for evaluating an inhibitory circuit applicable to a living body, and the use thereof. Herein the action of an inhibitory circuit on an excitatory circuit is evaluated on the basis of attenuation of the brain activity produced by activation of an excitatory circuit by the input of an inhibitory circuit by performing a step for inputting an inhibitory circuit by applying a second trigger in advance of a first trigger to an excitatory circuit activated by a first trigger which is a stimulus or challenge.

Abstract: A phase contrast transmission electron microscope apparatus has a long-life phase modulator, enabling changes in quantity of phase modulation, barely absorbing the electron beams, and not being influenced by irradiation of the electron beams. An electron microscope comprises an electron gun, a first laser beam irradiating process, being positioned between the electron source and an object lens, for irradiating laser beams onto the electron beams radiated from the electron gun, a second laser beam irradiating process, being positioned on a focal plane behind the object lens, for focusing and irradiating the laser beams upon the focus of the electron beams penetrating through a specimen, and a screen or a 2D electron sensor for detecting a specimen image in the form of distribution of intensity of the electron beams by an optical system.

Abstract: A method for manufacturing an optical element includes a bonding step of bonding a first and a second element portion to each other without interposing an adhesive therebetween. The bonding step includes: a first step of fixing the first and the second element portion with an intermediate layer disposed between these portion, the intermediate layer containing an element substitutable for a constituent element of a bonded portion in the first and the second element portion, the intermediate layer being colored; and a second step of integrating a part of the intermediate layer with the first and the second element portion, and making a part of the intermediate layer transparent to laser light by irradiating the intermediate layer with giant pulse laser light and causing it to be absorbed into the intermediate layer after the first step.

Abstract: A laser component is provided, including a laser medium and a transparent heat transmitting member, at least one of which is oxide. Bonding surfaces of the laser medium and the transparent heat transmitting member are exposed to oxygen plasma, and thereafter the bonding surfaces are brought into contact without heating. The laser medium and the transparent heat transmitting member are bonded at atomic levels, their thermal resistance is low, and no large residual stress is generated due to the bonding taking place under normal temperature. The process of oxygen plasma exposure ensures transparency of their bonding interface. The laser medium and the transparent heat transmitting member are stably bond via an amorphous layer.
