Title: Dry-etching method
Inventor: HIGUCHI FUMIHIKO
IPC: C23F4/00
Filed: 1992-05-19
Abstract: PURPOSE:To extend the selecting range of etching state by a method wherein the mixed gas containing the first gas containing bromine and the second gas containing halogen excluding bromine is fed to a processed body and then a polysilicon exposed layer is etched away using a plasma comprising the mixed gas turned into plasma state. CONSTITUTION:A silicon oxide film, a polysilicon film are laminated on a silicon substrate and then a wafer W formed on the polysilicon film as the processed body is mounted on a circular lower electrode 2B. Next, HBr gas as the first gas and HCl gas as the second gas are led into a vacuum chamber 1 through a gas leading-in pipe and gas diffused plates 13, 14 to be vacuumized through an exhaust pipe 15. Next, a plasma is produced by impressing the space between an upper electrode 2A and the lower electrode 2B with high-frequency power and simultaneously irradiating the space with ultraviolet rays to etch away the wafer W on the polysilicon film. Through these procedures, a high selection ratio is shown at high etching rate.

IPC: F17D3/12
Filed: 1993-05-27
Abstract: PURPOSE:To provide the liquid addition rate control system which conforms with variation in performance characteristics of a pump and makes disturbance hard to affect a flow rate. CONSTITUTION:An odorization controller 7 outputs stroke signals to diaphragm pumps 3a-3c. Consequently, the odorizing agent stored in a tank 2 is injected into the gas in gas pipes 1a-1c through pipes 8, 8a-8c, and 4a-4c. The flow rates of the odorizing agents sent from the diaphragm pumps 3a-3c are measured by Coriolis force flowmeters 6a-6c. The odorization controller 7 calculates, for example, the tertiary moving means of momentary flow rate signals outputted form the Coriolis force flowmeters 6a-6c at intervals of sampling time to find the mean momentary flow rate. The odorization controller 7 feeds this mean momentary flow rate back, and operates the stroke signals outputted to the diaphragm pumps 3a-3c according to an addition rate set value, the flow rate of the gas, and the mean momentary flow rate to control the flow rates of the odorizing agents sent from the diaphragm pumps 3a-3c to the addition rate set value.

Abstract: PURPOSE:To prevent the pollution of the inside of a recorder by a simple constitution in which an absorber whose volume is increased by absorption of liquid is set in a waste liquid trap, and the amount of waste liquid is electrically detected as the absorber expands in a recorder using a liquid. CONSTITUTION:Ink is directed into a waste ink trap 9 by action of a discharge recovery mechanism, and when the amount of ink to be absorbed by an absorber 10 is increased until a given amount close to fullness is reached, the absorber 10 is expanded and its upside is contacted with a contactor 11a. Whereupon, the contactors 11a and 11b are led to each other through ink absorbed into the absorber 10, and the condition is detected by CPU12.

Filed: 1993-06-23
Abstract: PURPOSE:To prevent peeling of a flange face of a mast rail by specifying carbon content of the mast rail made of carbon steels for machine structural use and Rockwell hardness of an outside diameter surface of an outer ring. CONSTITUTION:As for an outer ring 95 consisting of, for example, S55C, a track face 95a is normalized, and an outside diameter surface 95b is in the range of lower limit of 18-25 by Rockwell hardness C scale even when normalizing of, for example, S33C or S45C, is adopted among carbon steels for machine structural use having 0.30-0.50weight% of carbon content as a mast rail 91. For this reason, in a mast device, there is a difference in HRC of only 0-5 between hardness of the mast rail 91 and hardness of the outside diameter surface 95b of the outer ring 95 in a lift roller 96, and peeling of a flange face 91a of the mast rail 91 is suppressed because there is hardly a difference. As a consequence, a forklift which employs the mast device provides excellent durability.
