Title: Hydraulic control valve
Inventor: KOSUGI ISAO
IPC: F15B21/045
Filed: 1981-03-30
Abstract: PURPOSE:To permit it indeminification for the temperature of the whole hydraulic apparatus by allowing the position of a spool for setting a variable orifice to be determined by the balance between a rigidity retain force and the pressure in an auxiliary flow passage. CONSTITUTION:When flowing in a hydraulic control valve 22, working oil flows, in one part, in a main flow passage X constituted of an introducing hole 25, intermediate part between piston plates 28 and 29, discharge hole 26 etc., and flows, in the other, in an auxiliary flow passage Z constituted of a narrow hole 34, chamber 33, narrow hole 35 etc. If the viscosity of the working oi reduces because of the rise of temperature, the pressure in the chamber 33 lowers because of the reduction of the flow resistance. Accordingly, balance is lost, and a spool 27 is shifted leftward. Then, the sectional area of the flowing passage in a variable orifice Y is reduced, and the flow resistance of the main flowing passage X incraeses. When the viscosity of the working oil increases, the spool 27 shifts to increase the sectional area of the variable orifice Y and reduce the flow resistance of the main flowing passage X.

Title: Formation of metal layer
Inventor: SUMI HIROBUMI
IPC: H01L21/3205
Filed: 1991-02-21
Abstract: PURPOSE:To enhance barrier performance of Ti series barrier metal. CONSTITUTION:A Ti layer 9 and a TiN layer 10 are laminated sequentially while covering a contact hole 8 bored through a layer insulation film 7 oppositely to the source/drain region 5 of a MOS transistor. Inert substance, e.g. N2, is then ion implanted to destroy pillar crystal structure of the TiN layer 10 and to produce an amorphous TiN layer 10a. Consequently, a grain boundary providing a high speed diffusion path disappears thus suppressing diffusion of Al or Si. Material such as Al-1%Si is subsequently applied onto the entire surface through sputtering. At that time, the contact hole 8 has good burying characteristics. Furthermore, an Al metal layer 11 is patterned. Excellent barrier performance of the amorphous TiN layer 10a is verified based on measurement results of junction leak current.

Abstract: PURPOSE:To obtain a narrow band oscillation excimer laser which stably outputs a spectrum high in purity independent of a width of discharge by a method wherein a light beam emitted from a discharge chamber is turned around toward the discharge chamber to constitute two optical axes in the chamber, and a grating is arranged making the direction of lines provided to the grating nearly parallel with a discharge direction. CONSTITUTION:A grating 30 is so disposed as to enable the direction of lines provided to it to be parallel (coincident) with a discharge direction. Light beams are produced on an introduction optical axis which passes through a discharge chamber 20 from a rear mirror 70 and reaches the grating 30 as enlarged by a beam expander composed of prisms 41 and 42 and on an emission optical axis which passes through the discharge chamber 20 through the intermediary of the prisms 41 and 42 as reflected by the grating 30 and is emitted through a front mirror 10 as an oscillated laser beam L1. Therefore, a discharge width is prevented from expanding in the direction of lines provided to the grating 30 and a discharge beam does not change in divergence angle, so that a spectrum high in purity can be obtained. A cavity is made to become large in virtual length, a beam becomes small in divergent angle, and a spectrum of high purity can be obtained.

Abstract: PURPOSE:To pack a vessel without leaving creases on the lid, by replacing the air in the vessel with a higher gas than the normal temperature, when heat-sealing the opening edge of vessel charged with the contents of normal or lower temperature. CONSTITUTION:The contents of about 5 deg.C are charged in a vessel 11 by a charger 22. And hot air is injected from a hot air nozzle 23 into the vessel 11 and the air within the vessel 11 is replaced by the hot air. In this way, hot air is filled in the vessel 11 and the periphery of the lid 12 is heat-sealed at the opening edge by a sealer 25. In this time, the lid 12 is deformed plastically to cause creases 13 on the lid 12. After sealing, when the vessel 11 covered with the lid 12 is cooled naturally, the air inside the vessel 11 reduces its volume and hence, the inside of the vessel becomes vacuous. As a result, the lid 12 is tensed due to the negative pressure and generated creases 13 are stretched to make the lid clean.
