Abstract: Disclosed is a laser device including: a laser light source configured to emit laser light; a phase control unit configured to receive the laser light emitted from the laser light source, to control a spatial phase of a portion of the laser light, to emit the portion of the light as control light, and to emit another portion of the laser light as non-control light; a first optical system configured to irradiate an object with the control light emitted from the phase control unit; a detector configured to detect the non-control light emitted from the phase control unit; a second optical system configured to cause the non-control light emitted from the phase control unit to converge toward a detection surface of the detector.

Abstract: A microparticle trapping device includes: a fluid channel configured to be injected with a fluid including a microparticle; first and second electrodes configured to generate an electric field in the fluid channel; and an electrical insulator formed with at least one opening between the first and second electrodes in the fluid channel. The electrical insulator is disposed between the first and second electrodes so that an inhomogeneous electric field is made through the at least one opening between the first and second electrodes in the fluid channel, and the still other aspect is configured to trap the microparticle through dielectrophoresis.

Abstract: A computer sets a first timing condition for plural registers included in first design information of a semiconductor integrated circuit, and executes first logic synthesis to generate second design information. The computer sets, for the registers, a second timing condition having a smaller timing margin than the first timing condition, and executes second logic synthesis to generate third design information. The computer calculates an area change rate caused by a difference between the timing conditions, on the basis of the second and third design information with respect to each logic cone including a register at its end point, and categorizes the registers into a first group and a second group having smaller change rates than the first group, according to the change rate. The computer executes third logic synthesis with the second timing condition set for the first group and the first timing condition set for the second group.
