Title: Electron beam device
Inventor: OKABAYASHI HIDEKAZU
IPC: H01J37/075
Filed: 1986-04-17
Abstract: PURPOSE:To obtain electron beams of a desired current intensity distribution, by furnishing a mechanism to radiate laser beams locally at the cathode. CONSTITUTION:Linear electron beams radiated from an electron mirror consisting of a linear hot cathode 1, a wehnelt electrode 2, and an anode 3 are focused and deflected by an electron lens 5 and a deflector 6 respectively, and scanned over the surface of a sample 7. The laser beams 9 radiated from a laser radiator 8 are reflected by a reflection mirror 10, focused by a focus lens 12, and radiated on the hot cathode 1. Since the angle of the reflection mirror 10 is converted by a driving system 11, the laser beams can be radiated at a desired spot on the hot cathode 1. Therefore, electron beams of a desired intensity distribution responding to the purpose can be obtained.

CONSTITUTION:When fluid pressure is applied on a measuring pipe 11 made of ceramics, the maximum strain is generated at the central part in the longitudinal direction. Exciting coils 13 and 13' are wound around magnetic poles 12b. A pair of supports 12 and 12' have magnetic poles 12b having flanges 12c and said exciting coils 13 and 13'. The supports 12 and 12' are arranged so as to hold the measuring pipe 11 in a symmetrical pattern with respect to the axis of the pipe. The supports 12 and 12' are tightened with a pair of bands 15 and 15' made of magnetic bodies. A force which is reverse to the fluid pressure is applied on the measuring pipe 11 through a pair of the supports 12 and 12'. Initial strain which is opposite to the strain caused by the fluid pressure is generated. Therefore, the amount of the strain when the fluid pressure is applied can be made small. Thus, the thickness of the measuring pipe 11 made of ceramics can be made thin in comparison with the thickness when the single body of the ceramics pipe is used.

IPC: F24C7/02
Filed: 1980-07-01
Abstract: PURPOSE: To prevent unsatisfactory phenomenon such as food materials collopse incurred from dropping of the drop lid of a pot directly on the food by adoping a construction with which the drop lid does not fall.  
     CONSTITUTION: The pot is fitted with a plural number of projections in one or more levels on the same circumference of the side wall of the cooking pot, and the drop lid 2 has recesses 7 corresponding to the shape and the number of the projections 6 provided on the inner wall of the pot body 1. With the above constitution, the volume of food to be cooked and a position of the drop lid 2 can be adjusted so that the level of boiled stock 5 is at a proper height, i.e. a position about 1cm above the upper surface of the drop lid 2. Fixing of the drop lid 2 is determined by shifting the projections 6 of the pot 1 with relation to the recesses 7 of the drop lid 2. Bringing the projections 6 and the recesses 7 into coincidence permits the drop lid 2 to be moved down to a lower fixing position. Thus, even if cooking proceeds and solid food 4 is softened, the drop lid 2 does not drop, directly on the food, preventing the food shape collapse and the infiltration or separation of stock into and from the food.
