Abstract: A system and method of generating and acquiring phase contrast microscope images while minimizing interference with the intensity and optical quality of other microscopy modalities employing polarization and attenuation strategies for phase microscopy applications. A plane polarizing objective phase ring may be used in conjunction with a phase microscopy apparatus. Attenuated light may be controlled such that transparency may be selectively provided with respect to light in a predetermined plane. Illumination outside of the predetermined plane may be selected for phase microscopy applications. Accordingly, a polarizing objective phase ring effective for enabling polarized phase microscopy may reduce interfere with normal usage of the microscope for other applications such as, for example, fluorescence microscopy.

Abstract: An ECM apparatus includes a stationary cathode tool having a passage, and a drive mechanism for moving a bar-shaped workpiece through the passage of the cathode tool while simultaneously rotating the workpiece. Electrolyte flows, from a manifold on one end of the cathodic tool to a manifold at the other end, through the passage, between the wall of the passage and the workpiece. An electric current is simultaneously established in the electrolyte, between the wall of the passage and the workpiece. The internal shape of the cathodic tool wall has a gradual transition from a circular entry opening to a lobed exit opening, and lobes formed in the wall of the tool are shaped so that they twist in the direction of workpiece rotation, in order to form helical lobes in the workpiece.

Abstract: The code extraction unit extracts time information from a time signal. The block determination unit determines whether the extracted time information is correct by each kind of the time information. The time information collection unit collects time information determined as correct. The time information determination unit performs logic check of the collected time information, and determines whether correct information is collected for all kinds of the time information, and if not collected, stores time information determined as logically correct in a temporary storage unit. If correct information is not collected for all kinds in the time information collection unit, a time information modification unit updates the time information in the time information collection unit by the time information stored in the temporary storage unit. If correct information is collected for all kinds of the time information, the time information determination unit corrects time information retained in a timekeeping unit.

Abstract: An electromagnetic actuator with a smaller size and an increased strength is provided. In the electromagnetic actuator, a first arm portion and a second arm portion that connect the magnetic poles of a stator extend to the outside of a rotor housing. A first coil and a second coil are wound around the extending portions. In other words, the first coil and the second coil are exposed to the outside of the rotor housing. Accordingly, compared with a case where the rotor housing also houses the first coil and the second coil, the width of the electromagnetic actuator can be reduced by the thickness of the rotor housing. Thus, the electromagnetic actuator can be made compact.
