Title: Etching damage preventing method
IPC: H01L21/3065
Filed: 1992-03-27
Abstract: PURPOSE:To prevent an etched surface from being affected by ion or plasma emission which is leaked out from a plasma chamber by isolating a substrate from the plasma chamber so that the etched surface of the substrate is not exposed to the plasma chamber except when ions are applied thereto. CONSTITUTION:An etched surface 17 is arranged to be at a right angle to an extraction electrode 4 and at the same time a chlorine gas which makes etchant is supplied thereto within argon plasma at the time of supplying the etchant. Chlorine is exhausted outside a system by an exhaust device 11 at the time of purging the etchant. A substrate 16 is arranged so that the etched surface 17 is brought into being at a right angle to the extraction electrode 4 throughout the time of supplying the etchant and purging the etchant by function of a direction change over switch. Therefore, the etched surface 17 is not exposed to the plasma chamber 3. Then, the direction change over switch is controlled by a control section to be able to change the arrangement of the substrate 16 so that the etched surface 17 faces against the extraction electrode 4.

Title: Method of manufacturing radially corrugated spacer expander
Inventor: KOUROGI TAKEO
IPC: F02F5/00
Filed: 1984-04-12
Abstract: PURPOSE:To facilitate bonding even for those which have a narrow axial width by filling thermosetting resin in the opening of the inner circumferential corrugation of a spacer expander, which is then heated for hardening and bonding. CONSTITUTION:Thermosetting resin 5 which has a bonding capability with metal is filled in the opening 21 of inner circumferential waves 2 of both sides of the mating ends 41, which is then heated for hardening to be bonded tightly on the both sides of a spacer expander. In this manner, even a spacer expander having a narrow axial width can easily be bonded, and because the bonding strength is very high, it is unnecessary to provide a valve to prevent pieces from falling off.

Abstract: PURPOSE:To obtain a tape deck having the capacity for erasure of unnecessary recording part easily and accurately by fitting an erase head at a prescribed position on a tape contacted with a delay when the position is in contact with a reproducer head and applying an erase signal to the erase head in response to an erasure command. CONSTITUTION:The 2nd erase circuit 8 is provided to apply the erase signal to the 2nd erase head 3. This erase circuit 8 is activated by an output of a 2-input AND gate 9. When an erase command switch 10 is depressed during the reproduction of tape, since a high level is impressed to one input of the gate 9 during the operation, a high level signal is led to the output of the gate 9 so as to activate the erase circuit 8 for this time. Then, the erase signal is applied to the 2nd erase head 3 during this time so as to attain erasure of tape. In setting the distance between the reproducer head and the 2nd erase head 3 to a short value (in case of a compact cassette, the distance is selected as nearly 13mm. because of the structure of the cassette half), the erasure is attained almost the same time as the reproduction of the signal.
