  • Publication number: 20240101804
    Abstract: This bolus, which is for radiation therapy, can be deformed to match the shape of a human body surface, and has little deformation during therapy. The bolus forming material is a rubber composition containing ethylene-propylene rubber and a temperature-sensitive material. The bolus forming material has a JIS type A hardness of 20 or higher at 30° C., and thus is not susceptible to deformation. The bolus forming material has a JIS type E hardness of 10 to 60 at 70° C., and thus easily deforms. The bolus forming material shifts the peak of the percentage depth dose for electron beams and X-rays in the beam source direction at 0.8 to 1.2 times the thickness thereof. Therefore, the bolus forming material has dose characteristics in the depth direction that are substantially the same as a human body. After a sheet of the bolus forming material is heated to around 70° C., the sheet deforms.

  • Publication number: 20240106265
    Abstract: A backup power supply control system includes: a first semiconductor switch that switches a main power supply line to an electrically conductive state or an electrically non-conductive state; and an auxiliary power supply switch that switches an auxiliary power supply line to the electrically conductive state or the electrically non-conductive state. A first driving unit controls, in a non-failure state, a second semiconductor switch, connected between a gate and source of a first semiconductor switch, OFF and thereby controls the first semiconductor switch ON. The first driving unit ensures, in the failure state, at least a gate-plateau voltage of the first semiconductor switch as a drive voltage for the second semiconductor switch. When a failure detection unit detects the failure state, the first driving unit controls the first semiconductor switch OFF by controlling the second semiconductor switch ON and a second driving unit controls the auxiliary power supply switch ON.

  • Patent number: 11938931
    Abstract: A stop assist system for moving a moving body to a stop position and making the moving body stop at the stop position includes: an external environment recognizing unit that recognizes an external environment of the moving body; and a moving body control unit that executes a driving process to make the moving body travel to the stop position based on a recognition result of the external environment recognizing unit. The moving body control unit suspends the driving process when, while the moving body is traveling to the stop position, the moving body control unit determines, based on the recognition result, that there is an object within a range of a prescribed lateral threshold value on a lateral outside of the moving body and the object extends over a prescribed longitudinal threshold value or more along a travel direction within the range.
