Title: Evaluation of residual life of heat resistant steel
Inventor: NISHIMURA NOBUHIKO
IPC: G01N33/20
Filed: 1986-04-02
Abstract: PURPOSE:To evaluate residual life certainly in a nondestructive manner within a short time from the change in the structure of heat resistant steel, by analyzing the concn. of the element of a minute area at each analytical point of said area in an arbitrary range and setting the ratio of an entire concn. range to all of analytical points to an areal ratio to calculate a residual life evaluation reference line chart. CONSTITUTION:The concn. of Mo within the 1mm<2>-area of ferrite type heat resistant steel is analyzed and measured at a large number of points by an X-ray microanalyser and the ratio of an entire concn. range to the number of all of analytical points is set to an areal ratio to calculate the max. value of said areal ratio and the half value width of a distribution spectrum. The max. value and the half value width are correlative to a creep breaking life consumption ratio. A residual life evaluation material of a used material of every kind and the measured values of heat resistance steel used for along time is compared with said chart. Therefore, residual life can be certainly evaluated from structural change in a nondestructive manner within a short time.

Title: Programmable controller
Inventor: OZAWA HIROMITSU
IPC: G05B19/05
Filed: 1988-03-31
Abstract: PURPOSE:To eliminate the participation of a buffer program as necessary and to improve the handling performance of a programmable controller PC by using a means which transfers the data of a specific type directly to an output circuit with no intervention of the buffer program. CONSTITUTION:The data are sent to a lower rank PC5 from a higher rank PC1 and then transmitted as they are through an output circuit 52B of the PC5. In this case, the PC1 outputs the corresponding data out of an output circuit 11D allocated as the direct output out of those types of link data. This output data is applied to a link terminal allocated as the direct output of the PC5 via a lower rank transmission line 3. Thus the PC5 transfers the data received from the PC1 as the direct output directly to the circuit 52B with no intervention of a buffer program. As a result, said output data is immediately applied to an object process P.

Filed: 1984-04-18
Abstract: PURPOSE:To prevent the blinding of a screen by suppressing the evaporation of solvents in printing ink by providing a film or sheet to cover the screen for a squeegee device and a scraper. CONSTITUTION:The end of a film or sheet 7a wound around a winder 10 is fixed to a squeegee holder 4a through a presser 4a', and the end of a film or sheet 7b wound around a winder 10' is fixed to a scraper holder 5a through a presser 5a'.

Title: Electron gun
Inventor: NAKANISHI TOSHIO
IPC: H01J29/50
Filed: 1986-04-03
Abstract: PURPOSE:To enable any deflection aberration caused by deflection magnetic field to be corrected electrostatically without deteriorating performances such as acceleration, focusing and convergence that are basic functions of an electron gun, by applying a focusing voltage synchronous with the deflection magnetic field of an electric beam to a quadripole. CONSTITUTION:With regard to a quadripole 6 arranged in a drift space, if a voltage applied to, for example, vertical electrode pieces 6b, 6d is more positive than a voltage applied to horizontal electrode pieces 6a, 6c, the circuit cross-section of an electron beam 7 is deformed in a longitudinal ellipse owing to the effect of static electric field during its passage through the quadripole 6. Thus, such a deflection aberration as causing a cross-sectional form of a lateral ellipse is compensated in advance before such a deflection takes place on a phosphor screen. Since this action is carried out in a drift space, substantial acceleration or decelaration of the electron beam 7 can never take place together with no trend to deteriorate the focusing function of an electron gun.
