Abstract: There is provided a rotary electric shaver which can easily prevent an outer blade which is undesirable to be brought into contact with a skin from coming into contact with the skin, by reducing the number of contact times of the outer blades in a head with the skin, even when the shaver is used in a state where the head is substantially parallel to the skin. A rotary electric shaver includes a main body having a drive shaft, and a head connected to the main body. At least one of a plurality of blade units has a fulcrum plate, a turning plate, a spring, and a fixing plate, and has a lock mechanism capable of changing a height position of at least one of outer blades corresponding one-to-one to the blade units.

Abstract: A medical image processing device according to an embodiment includes a region-of-interest acquirer, a treatment plan acquirer, a degree-of-influence calculator, and a display controller. The region-of-interest acquirer is configured to acquire a partial region within a body of a patient as a region of interest. The treatment plan acquirer is configured to acquire treatment plan information determined in a planning stage of radiation treatment to be performed on the patient. The degree-of-influence calculator is configured to calculate a degree of influence representing an influence on the region of interest up to a range until radiation with which the patient is irradiated reaches a target portion to be treated within the body of the patient. The display controller is configured to generate a display image in which information regarding the degree of influence is superimposed on a current fluoroscopic image of the patient and causes a display to display the display image.

Abstract: There are described a process for electric discharge machining of a work, which uses deionized water containing no rust preventing agent, as working liquid, and an apparatus therefor. The electric discharge machining apparatus additionally has a high-frequency AC applying device, a grounding electrode and a pair of applying electrodes in which are immersed in the deionized water to alternatively apply high-frequency AC voltage to the applying electrodes for decreasing oxidation-reduction potential of the deionized water.
