Title: Scanning speed reduction region automatic setting method in digitizing device
Inventor: SASAKI SHUNICHI
IPC: B23Q33/00
Filed: 1988-04-30
Abstract: PURPOSE:To shorten scanning time as a whole by setting a prescribed speed reduction region, when a model shape sudden change point is once detected, so that return processing can be eliminated in the subsequent scanning. CONSTITUTION:When a shape sudden change detecting part 3 detects a model shape sudden change point on in the scanning direction via the information of a displacement read part 1 and a present position read part 2, a scanning control part 4 sets and stores a prescribed speed reduction region before and behind thereof. And, based on a scanning information SI, a speed reduction region processing part 8 outputs, to the scanning control part 4, speed commands VID, VII by which when a stylus 8 enters the speed reduction region, the speed is reduced; while when it passes the speed reduction region, scanning speed is returned to the initial speed, and further it checks the presence of a new model shape sudden change point, and based on the result, it continues or releases the speed reduction region. Thus, return processing can be eliminated, and the scanning time as a whole can be shortened.

On receiving the above-mentioned output signal, gate 21 operates to cut off signal 22 to power circuit 23 of strobe flash 13. In this constitution, strobe flash 13 flashes interlocking with the shutter of a camera only when sunshine is insufficient, so that the lifetime of the strobe flash can be prolonged.

IPC: F23J11/00
Filed: 1987-05-01
Abstract: PURPOSE:To send out exhaust gas flowing in a dust without touching an inner wall by a method wherein air is supplied to a circular nozzle for the exhaust gas of a stack, which is placed on the way to a stack, from an air blasting device such as a blower, etc. and air forming straight streams with uniform velocity is ejected to form a fresh gas membrane on the inner surface of an cylinder. CONSTITUTION:A circular nozzle 1 for stack exhaust cylinder has the stack connected to stack connection flanges 6 and the nozzle 1 is used in the condition that the nozzle is placed on the way to the stack. That is, when air is supplied from an air blasting device such as a blower, etc. while the stack is in use, air flowing into an air stream distributor from an air supply port 9 is discharged from a ring-shaped ejecting slits 8 as the air forming straight streams with uniform velocity by an air stream distributing action of each air stream distributing fin 10 and forms a fresh gas membrane on the inner surface of an inner cylinder along the inner wall of the stack. Since negative pressure perpendicular to the inner surface of the stack is generated on the inner surface of the stack by this ejecting flow velocity, exhaust gas flowing in the inner part is sent without touching the inner wall by an air-absorbing action accompanying the negative pressure.
