IPC: F16L11/12
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a high pressure fuel supply system, for reducing tensile stress applied to the corner part of a passage member forming a high pressure fuel passage, to improve the pressure resistance of the passage member. SOLUTION: An accumulator is constituted of the outer and inner peripheral members 10 and 20 of an accumulator type fuel supply system 1, and the outer diameter of the member 20 is slightly larger than the inner diameter of the member 10 in a condition before pressing the member 20 into the member 10. The pressing of the member 20 into the member 10 compresses the whole periphery of the member 20, thereby surely applying compression stress to the corner parts 22 and 23 of the member 20. The accumulation of high pressure fuel in an accumulator chamber 21 applies tensile stress to the corner parts 22 and 23 by fuel pressure in the chamber 21. Compression stress is applied to the corner parts 22 and 23 in a direction opposite to the tensile stress, thereby reducing the tensile stress applied to the corner parts 22 and 23.  Consequently the pressure resistance of the corner parts 22 and 23 can be improved to make the fuel pressure accumulated in the chamber 21 be high pressure.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a rotationally a symmetric aberration in a projection optical system, which occurs due to exposure, by making a luminous flux incident on the projection optical system while a first object and a second object are scanned at a velocity ratio corresponding to the projection magnification of the projection optical system. SOLUTION: A reticle stage is moved before regular shot exposure and a lens illumination mark 103 is brought to a standstill under the rectangular illumination area 125 of an illumination system 101. Then, preliminary exposure for continuously exposing the lens illumination mark 103 for prescribed time is executed. The lens illumination mark 103 is constituted of a luminous flux divergent element, illumination light from the element is set to be divergent luminous flux and it is made incident on the respective lenses of a projection lens PK so that it becomes rotationally symmetric with respect to an optical axis. Thus, the illuminated range 120 of the lens 104 is illuminated so that the lens 104 is set to be rotationally symmetric and the whole lens is made to be a thermally saturated state.  Even if illumination light which is not rotationally symmetric is received at the time of regular shot exposure, the occurrence of asymmetric aberration such as astigmatism is prevented.

Abstract: PURPOSE:To perform turnoff operation uniformly on an entire substrate with a simplified vessel structure and improve assembling reliability and productivity by providing a gate current extracting part at the center of a substrate and forming gate current passages extended from the extracting part isotropically and radially reaching the outer circumference of the substrate. CONSTITUTION:A gate current extracting part 31 with which a collector electrode 4 is in contact is provided at the center of a substrate, and gate current passages 32 without segment emitters 2 are formed isotropically and radially from the extracting part 31. That is, gate current 11 is collected to the gate current extracting part 31 via the gate current passage 32 closest to a gate electrode 3 surrounding the emitter 2 and extracted from the collector electrode 4 to an external terminal 41. On the other hand gate current 12 directly flows to the extracting part 31 from a gate electrode close to the current extracting part 31. Therefore gate current at the time of turnoff is finally extracted outside from the collector electrode 4 at the center so that complicated and highly precise groove processing of a cathode post 6 and a contact electrode plate 8 is not necessary. Thus assembling operativity and reliability can be improved.

Abstract: PURPOSE:To automatically scatter the high frequency components which are easily produced by an A/D converter and to improve the S/N characteristic by providing a signal level detecting part, a clock dither setting part, and a clock dither supply part and feeding the output of a digital filter back to the input side. CONSTITUTION:The digital output Dout of a digital filter FIL is inputted to signal level detecting part SLD and then inputted to a clock dither supply part CDK via a clock dither setting part CDS. The output of the part CDK is fed back to an adder ADD where an analog signal Ain is inputted. If the output of an A/D converter, i.e., the output Dout of the filter FIL contains many noise components, the part CDS selects the clock dither level to be added to the input Ain and informs the part CDK of this selecting instruction. The part CDK outputs the necessary signal to the part ADD to add the signal to the input signal Ain. In such a constitution, the clock dither can be optionally varied and the high frequency components are scattered. Thus the S/N characteristic is improved.
