Title: Impregnation-type cathode
Inventor: TSUJIKAWA KENICHI
IPC: H01J1/28
Filed: 1981-08-21
Abstract: PURPOSE:To obtain a long life impregnated-type cathode secular-change of whose electron emission characteristic is small, by a using a tungsten layer of large porosity rate as the lower layer and by using tungsten layer of small porosity rate as the surface layer of the captioned cathode. CONSTITUTION:The figure shows as impregnated-type cathode 10 designed by the present invention, a holding cylinder 3 made of molybdenum, and a cathode structure 11 of a heater 4 buried in sintered alumina 5. The captioned cathode 10 is a laminated structure consisting of two layers, that is, the surface layer 1 with the porosity rate of 20% and the lower layer 2 with the porosity rate of 40%. In the captioned cathode 10, the evaporation amount of Ba can be suppressed and the necessary amount of Ba can be supplied by reducing the porosity rate of the surface layer 1, so that the consumption-time of Ba can be prolonged. On the other hand, by enlarging the porosity rate of the lower layer 2, the supply amount of Ba from the inside of the vacant-hole to the surface layer can be increased, the depreciation of Ba-covering degree necessary for electron emission can be suppressed, and the secular-change of current can be minimized.

Title: Rotor of squirrel-cage electrical rotary machine
Inventor: NARUSE TOMOHIRO
IPC: H02K17/16
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To reduce high tensile stresses produced at a conductor bar and the base of an end ring by varying the shape of slits in the axial direction in order to constrain thermal expansion of the conductor bar in the axial direction, forming a projection or recess on the conductor bar in the axial direction, and securing the conductor bar on a core in the axial direction. SOLUTION: Slits are enlarged in proximity to an end ring, and a projection 9 is formed on a conductor bar. This state of transformation in the conductor bar in the axial direction at this time is constrained by the projection 9, and no gap is produced between the end ring and a core. For the reason, bending deformation does not takes place in the conductor bar, and the bar or the base of the end ring is not brought into tensile state. With respect to stress distribution at this time, tensile stress on the base is reduced. Rather, compressive stress is exerted by flexion in the end ring being restrained. The projection on the conductor bar can be easily formed by only integral molding, using aluminum die casting.

The packet is resolved the communication control part 16 at the side of the information transmitting device 12 and the request speed is given to the encoding part 15.  The encoding part 15 changes the value of encoding speed into the requesting value.

Then, higher components  are eliminated by LPF 1 and 2, and waveforme distortion is eliminated by equalizer  11, and after that, the transmission signal point is decided by decision circuit 12. In  this case, x coordinate value x 1  is temporarily stored in register 13 by a clock pulse  from clock generator 14, and y coordinate value y 1  from equalizer 11 is stored in  register 13 by the next clock pulse, and simultaneously, coordinate value x 1  is transferred to register 15. Then, digital values stored in registers 13 and 15 are converted to analogue values by D/A converters 16 and 17 and are displayed on oscilloscope 10. As a result, the number of coordinate signal lines, etc.,  can be reduced  to simplyfy the circuit.
