Title: Dry etching
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1991-12-17
Abstract: PURPOSE:To provide a method of etching a GaAs/AlGaAs laminate in a highly anisotropic, highly selective, less contaminating manner without using chlorofluorocarbon. CONSTITUTION:Gate recesses of a HEMT are formed by etching an n<+>-GaAs layer 5 on an n<+>-AlGaAs layer 4 using a vaporized mixture of S2F10 and S2Cl2. The vaporized mixture contains S2F10-xClx produced by halogen exchange. This supplies various etching species that cannot be obtained from only one kind of gas, and the resist selectivity may be improved owing to changes of composition and structure of carbon polymer. Since sulfur is deposited to form a side wall protective film 7, anisotropic etching proceeds and the selectivity of the underlying layer is maintained by the generation of AlFx. If nitrogen is added to the vaporized mixture, it is possible to provide side wall protection by (SN)x.

Title: Device and method for processing image
Inventor: SHIRAHAMA AKIRA
IPC: H04N7/01
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To keep precision in an original signal when line conversion whose expansion rate is not an integer value is performed by a video signal with interlace precision. SOLUTION: An interpolation interval Vdp obtained from an original image and an image size after conversion is stored in a register 13, and is acumulatively added by an adder 14 through a selector 16 from the register 15. By the selector 17, a [0.5] is selected in an ODD field, and a [0] is selected in an EVEN field based on an odd/even field discrimination signal to be supplied to the selector 16. The output of the selector 17 is selected by the selector 16 for a vertical blanking period, and the register 15 is initialized. Then, an offset value [0.5] is added to the cumulated value of the Vdp in the ODD field, and the Vdp is cumulatively added again. A read-out address (n), linear interpolation coefficients qn1 , qn2 of a line are obtained based on this cumulative addition value.  Since the offsets corresponding to the start points of the scanning of the ODD field and EVEN field are added when the Vdp is cumulatively added, the interlace precision is kept.

A through-hole 64 is formed in the blower 28 for feeding air and at a position, where the optical type sensor 60 and the internal part of the combustion chamber 14 are intercoupled. This constitution introduces flame intermittently to the optical type sensor 60 via the through-hole 64 of the blower 28 for feeding air, when flame light is generated in the combustion chamber 14.  Namely, the optical type sensor 60 works to detect ignition, extinction of flame, and flame failure in the combustion chamber 14 and works to output the number of revolutions of the motor 24 as a pulse signal to a control circuit 30. This constitution eliminates sensors which were needed heretofore, to detect the number of revolutions of the motor 24 and reduces the cost and size.
