IPC: F04D29/30
Filed: 1978-06-12
Abstract: PURPOSE: To reduce stress concentration and increase strength by providing cut lines alternately, each having a circular hole at its ends.  
     CONSTITUTION: Of cut lines 1 provided on flat plate 10, cut lines 1 perpendicular to the shaft are arranged alternately. Joint 4 of vane part 2 and machine part 3, surrounded by cut lines 1, is taken large. Circular holes 11 provided at the ends of cut lines 1 reduce stress concentration at joint 4. Consequently, by providing cut lines 1 alternately, the cross section of the break part, due to the centrifugal force and the impulsive force, is made large compared with conventional devices. By providing circular holes at the ends of the cut lines, stress concentration is reduced compared with conventional devices. By this, it is possible to increase the strength of the joint against the centrifugal force and the impulsive force markedly.

Title: Method and device for inspecting wafer with pattern
Inventor: YAMADA SATORU
IPC: H01L21/66
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To accurately inspect even a wafer which is patterned using different aligners. SOLUTION: Each correction value based on the error to a design coordinate is computed for every combination of aligners A, B and C and photomasks (a) to (i), and when wafers 40 with an actual pattern are inspected, the design coordinate is corrected by the combinational correction value of the aligner A and the photomask (a) which are used when the wafer 40 is patterned. A wafer with correction value setting pattern is formed for every combination of each aligner and each photomask, the error with design coordinate is measured for every wafer with correction value setting pattern, and the correction value for every combination of each aligner and photomask is computed based on the error of measurement. Consequently, as the difference in inspection result between the aligner and the photomask can be prevented, high inspection accuracy can be maintained even under the condition where the photomask is used in plurality of aligners, and the lowering of the yield of production of semiconductor device can be prevented.

Title: Image forming condition control method for image forming device
Inventor: BISAIJI TAKASHI
IPC: G03G15/08
Filed: 1989-03-27
Abstract: PURPOSE:To evade a malfunction in which image forming conditions are mistakenly corrected when not required by detecting a toner concentration in a developing device, and increasing the interval of timing of the correction of image forming condition based on the information. CONSTITUTION:A toner concentration in the casing of the developing device 2 is detected by a toner concentration sensor 6 as a toner concentration detecting means; when a toner concentration is lower than a value set in advance, a replenishment motor 7 is actuated to replenish the toner from a toner replenishing hopper 8. At this time, the interval of timing of the correction of image forming condition is increased based on information from the toner concentration sensor 6. That is, the use of the toner sticking information at a low concentration is not required for the correction of image forming conditions by delaying the timing of the detection. Thus, the setting of image forming conditions which do not meet the condition of an image carrier 1 can be evaded.
