Abstract: PURPOSE: To improve the capability of air exhausting as a whole by a method wherein oil smoke, etc. are induced and collected by an air current from a blower before they are diffused sufficiently during a rise from their generating sources, and the oil smoke, etc. can be induced even when they reach a height.  
     CONSTITUTION: When driving the blower 7, air in the upper indoor space of a main body frame 1 is sucked through a suction port 10, ais discharged in the direction along a surface F of a top plate 2 as shown in an arrow 18 from a jet 11, flows in a stratiform condition on a lower surface of the top plate 2 and is discharged from an exhaust port 4. When the oil smoke, etc. rising under this condition reach near the lower surface of the top plate 2, they are induced by the air current 18 discharged from the jet 11 of the blower 7 as shown in an arrow 18a, subject to the  pushing-out action and discharged from the exhaust port 4. Accordingly, the oil  smoke, etc. are positively induced and collected while an ascending current of the  oil smoke, etc. is added to the air current thus improving the capability of exhaustion.

Title: Ion implantation type magnetic bubble element
Inventor: HOSOE YUZURU
IPC: G11C19/08
Filed: 1986-05-06
Abstract: PURPOSE:To eliminate the change in the characteristic of bubble holding region by ion implantation by forming a magnetic garnet film so as to have a partially decreased thickness and subjecting said region to deep ion implantation to form an intra-surface magnetized region. CONSTITUTION:The magnetic garnet film 1 formed on a nonmagnetic garnet substrate 2 is partly thinly formed. The region is thereafter subjected to the deep ion implantation to the extent that the ions arrive at the substrate 2 to form the intra-surface magnetized region 3. A charged wall 4 is generated by impressing an intra-surface magnetic field to said region and a magnetic bubble can be driven by the magnetic pole of the charged wall. Since the ions are not implanted to the region where the magnetic bubble 5 exists according to such element constitution, the instability of the bubble is obviated.
