Inventor: KIKUCHI KENSHO
IPC: B28D1/14
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of turbulent flow in a dust suction passage by providing first and second dust suction passages so that the side end of the rotary tool of the first dust suction passage communicating with the second dust suction passage is positioned on the side of a core bit from the inner periphery on the side of the rotary tool of the second dust suction passage. SOLUTION: A screw groove 4C to be threaded with a core bit 2 is formed at a fixed dust collection shank 4. Next, as a first process, the second dust collection passage 4b piercing in the diameter direction of the dust collection shank 4 is formed by drilling processing and, thereafter, as a second process, the first dust collection passage 4a is formed in the axial direction of the dust collection shank 4 by drilling processing so as to communicate with the second dust collection passage 4b. By this constitution, the leading end part on the side of the anti-core bit 2 of the first dust collection passage 4a does not protrude into the second dust collection passage. As a result, no turblent flow is generated in the dust collection shank 4 and, therefore, a cut powder can be efficiently sucked.

Abstract: PURPOSE: To lower the specific resistance of the epitaxial-growth semiconductor layer of a semiconductor device, obtained by mounting a normal element and I 2 L element on one chip, only at the I 2 L element part definitely.  
     CONSTITUTION: On p-type Si semiconductor substrate 11, Si oxidized film 12 is formed and patterned through photo lithography to form burying-diffusing openings, through which Sb is vapor-phase-diffused to form n + -type buried layers 13 1  and 13 2 . Next, oxidized film 12 is patterned through photo lithgraphy to form impurity- diffusing openings, through which phosphorus ions are injected to form N + -type impurity layer 14. Then, oxidized film 12 is removed and B ions, for example, are injected to from p + -type impurity layer 15. Finally, n-type Si semoconductor layer 16 is grown through normal vapor-phase epitaxial growth. At this time, since phosphorus diffused from impurity layer 14 to the outside is neutralised by impurity layer 15 of B of the opposite conduction type, the specific resistance of the part except the circumference of impurity layer 14 as the effective emitter part will not decrease down to an undesired value.

Title: Overspeed detector of operatorless vehicle or the like
Inventor: FUJITA KATSUHISA
IPC: G05D1/02
Filed: 1984-07-10
Abstract: PURPOSE:To accurately detect an overspeed by previously calculating the delay time required to arrive at the objective traveling speed, and judging the traveling speed after the delay time at the deceleration time. CONSTITUTION:When a speed command signal SG1 for accelerating to 5.0km/hr is output, for example during traveling at 2.5km/hr, a detection controller 1 forms speed variation data at the acceleration from 2.5km/hr to 5.0km/hr, calculates its delay time T1, and stores it in a memory 5. Then, when a speed command signal SG1 for decelerating to 2.5km/hr is output, the controller 1 forms decelerating speed variation data. Simultaneously, the delay time T1 at the accelerating time corresponding thereto is read out, it is judged as being overspeed when the traveling speed signal SG2 after T1 time is larger than the travelling speed based on the signal SG1 to operate an alarm lamp.
