Title: Rotor spider shaft
Inventor: KANZAKI HIDETOSHI
IPC: H02K1/22
Filed: 1986-08-11
Abstract: PURPOSE:To reduce stress convergence produced to a welded part, by enlarging the radius of curvature of build-up welded parts as its surface on both ends in the axial direction of a projected streak segment welded to the outside circumference of a shaft approaches the outside circumferential surface of the shaft. CONSTITUTION:Multiple pieces of projected streak segment 12 are radially arranged along the axis of a shaft 11 to the outside circumference of the shaft. The whole girth of a projected streak segment 12 is welded. The surface of the build-up welded parts 13 of both ends in the axial direction of the projected streak segment 12 is formed into a circular arc of which the radius of curvature grows larger and larger in sequence from the end face of the projected streak segment 12 to the outside circumferential surface of the shaft 11. In this way, no stress convergence will be produced from the tip point A of the projected streak segment 12 to the point B of the outside circumference of the shaft 11 along the surface of the build-up welded part 13. As a result, the strength increases.

Filed: 1983-10-11
Abstract: PURPOSE:To keep a member for regulating a toner layer damage-free for a long period of time and to prevent toner filming on the surface of the regulating member and a carrying body on which the uniform non-magnetic one-component toner layer is formed by specifying the coefft. of friction of said carrying body at a prescribed value. CONSTITUTION:A non-magnetic one-component toner layer controlled to a uniform layer thickness by a regulating member 34 is formed on the surface of a carrying body 31. If the body 31 is formed to have the coefft. of friction ranging 0.02-0.3, the coefft. of friction between the body 31 and the member 34 decreases and the member 1 is kept damage-free for a long period of time. Less friction heat is generated on account of the decreased coefft. of friction and the carrying body and regulating member are prevented from having the toner film which is the cause for uneven development.

Filed: 1989-07-24
Abstract: PURPOSE:To prevent the wall of a working chamber from being melted by providing a deviation detecting circuit for monitoring a variation of a level of a detection waveform of an electron beam detecting device and detecting a fact that an electron beam is deviated from an object to be worked. CONSTITUTION:In the case an electron beam 3 is welding an object 4 to be welded, a large quantity of reflected electrons or secondary electrons are generat ed, therefore, a DC level of a detection waveform of an oscilloscope 13 is high. When an electron beam 3' deviates from an object 4' to be welded, the secon dary electron 9 decreases suddenly being in inverse proportion to the square of a distance, therefore, the DC level of the detection waveform becomes low. By detecting the time 17 of the instant of this deviation by a deviation detecting circuit 15, the generation of the electron beam 3 can be stopped before melting a wall of a welding chamber 16. In such a way, melting of the wall of the working chamber is prevented, and it can also be detected that the electron beam deviates from the object 4' to be worked.

Abstract: PURPOSE:To improve the accuracy of proximity effect by providing a drawing pattern for detecting that the accumulated energy by the electron beam at the position of arrangement has reached a certain value, having such a size as not to affect the drawing area density and being arranged approximately at the center of a pattern. CONSTITUTION:An electron beam drawing pattern is composed of a pattern 1, which decides drawing area density, and a pattern 2 for detection, which does not affect the drawing area density but detects that the accumulated energy of an electron beam at the point has reached a certain value from the pattern after development. The area pattern 1 is a uniform pattern where the lines of drawing parts L in width are arranged intervals S apart. Accordingly, defining that the drawing area density is A, A=L/(L+S). For the amount of irradiation given to the area pattern 1, the accumulated energy at the center of the detection pattern is sought by the specified formula. Hereby, the drawing pattern can be selected larger enough than the range of rear scattering, and reflection coefficient can be sought independent of other proximity effect pattern.

Abstract: PROBLEM TO BE SOLVED: To provide a rolling bearing provided with ceramic rolling elements, the production costs of which are lowered down though its performance is nearly as high as that of a bearing provided with ceramic rolling elements high in grade as shown by a conventional example. SOLUTION: It is discontinued that each ceramic rolling element 3 is formed into a conventional configuration high in grade in such a way that there exists almost no pore, on the contrary, it is formed into a configuration that there exist at least 100 pores of 3 μm to 30 μm per 1 mm2 on the surface and the inside of the rolling element 3, or into the other configuration classified as a middle class in grade permitting the number of pores to exist therein. Thus, the manufacturing process of each ceramic rolling element 3 can be simplified in process as compared with a conventional one, and its pressure withstanding strength can be sufficiently increased even though processing pressure is dropped down in a sintering process.

Abstract: PURPOSE:To permit dealing with the case of changing the raw material and changing  the characteristics of produced gases in the stage of adding a gas for carburetion to a  gas produced by denaturing hydrocarbon with O2 rich air and steam by changing the  concn. of O2 in the O2 rich air within a specific range. CONSTITUTION:The water and hydrocarbon from supply sources 1, 3 are preheated  with a preheater 9. Part of the preheated water is heated together with the O2 rich air  of 30-90% concn. of O2 from a line 19 further in a preheater 15 and is supplied as a  mixture of the O2 rich air and steam to a modifying furnace 23. Here if the concn. of O2 is <30%, the calorific value of the modified gas is low, the rate of combustion is  low and the thermal efficiency during production is low. On the other hand, in excess  of 90%, the gas is easy to fire prior to arrival at the catalyst beds. Even if the raw  materials are changed by the change of the concn. of O2 in the above-mentioned range,  the gas of approximately the same characteristic is obtained and further with the  same raw materials, the gases of different characteristics are obtained. On the other  hand, the hydrocarbon out from the preheater 9 is modified in the furnace 23, and  flows through a water replenisher 29, a CO converter 35, and preheaters 15, 9, by  which a gas for carburetion is mixed therewith. This gas is cooled in a water sealed  scrubber 47 and is discharged to the outside of the system.
