Patent JP-H05102095-A (JP)
Title: Dry etching method
Inventor: SATO JUNICHI
IPC: H01L21/3065
Filed: 1991-10-08
Abstract: PURPOSE:To anisotropically etch an Al group material layer excellent in resist and base material selectivity without using BCl3. CONSTITUTION:After removing natural oxide film 7 on the surface of Al-1%Si layer 6, Al-1%Si layer 6 and barrier-metal 5 are etched using S2F2/Cl2 mixed gas. Cl* generated dissociation from Cl2 acts as main etching seed and S generated from S2F2 acts as a component for a side wall protective film 9, anisotropic working possible even under low bias. Since above stated mixed gas does not contain reducing substances such as BCl3, etc., the selectivity against a SiO2 interlayer insulating film 1 which is a base material improves. The deposited S can be easily removed through sublimation when a wafer is heated, thus can not be the cause for particle pollution. Only in the removal process of natural SiO2 film 7, reducing substances may be used.

Title: Thermal battery
Inventor: TERASAKI MASANAO
IPC: H01M6/36
Filed: 1989-11-06
Abstract: PURPOSE:To allow discharging for a long period without increasing a heat insulator for heat insulation by making the number of laminated cells of power generating blocks on both ends larger than the number of laminated cells of power generating blocks on the inside. CONSTITUTION:The number of cells of power generating blocks 1 and 4 on both ends is larger than the number of cells of power generating blocks 2 and 3 on the inside, and power generating blocks 1-4 are electrically connected in parallel. Since the number of laminated cells of power generating blocks 1 and 4 on both ends is larger, the discharge voltage is higher, power generating blocks 1 and 4 are more preferentially discharged than power generating blocks 2 and 3 on the inside, and the discharge is completed earlier. The discharge rate of power generating blocks 2 and 3 on the inside is small at the initial stage, but the rate of the discharging current is increased as the discharge capabilities of power generating blocks 1 and 4 on both ends are reduced and the terminal voltage is reduced. The discharge of power generating blocks 1 and 4 on both ends is completed before the temperature of power generating blocks 1 and 4 on both ends becomes the operating temperature or below, and power generating blocks 2 and 3 on the inside are continuously discharged thereafter. A long life is obtained without increasing the quantity of a heat insulator.

The leading block 1-1 is arranged (2) at the position of a search pointer 2 from an initial state (1), and the pointer 2 is moved for 1/4. In the state (3) of generating two files, the pointer is moved for 1/8 so as to deal with the generation/erase of the file as prescribed. In a state (6), the pointer 2 shows 1/2 in a state (6) but since the block 1-1 is already arranged, the next 1/4 is investigated, the leading block 1-6 is arranged in the empty area, and the pointer is moved for 3/4. When the size of the file is small, continuous areas can be allocated to a lot of files. The files in a big size are allocated to several continuous areas. The number of times for the I/O of files is reduced.

Abstract: PROBLEM TO BE SOLVED: To avoid the wear, degradation and the like of peripheral elements including rollers by composing paper feeding mechanism of a feed pressure roller having a plurality of magnets on a shaft, and a jam release cover provided with a plurality of coils opposedly to a plurality of magnets. SOLUTION: A coil 5 forming a pair with a magnet 4 disposed on a shaft 3a of a feed pressure roller 3 is held to a jam release cover 6. The wound directions of the coils 5 disposed plurally are the same. When voltage is applied to make a current flow to these coils 5, magnetic field is generated from the center of the coils 5. When the surface poles of the coil 5 and magnet 4 are made like poles, resiliency is generated between both of them. With this resiliency, the feed pressure roller 3 presses a feed roller 2 in an opposite direction to the coils 5. Pressure can thereby be applied to the feed pressure roller 3 in a contactless state.
